Hayase Nagatoro/Biography

Early life
Hayase was born on April 1 in, , the third child of the Nagatoro family. She has a close relationship with both her older brother Ichirō and her older sister, while her parents are middle class that often work late. She grew up in a house in the suburbs right in front of a park, under a. Hayase had been a until at least the age of 7; as a child she went every year to the summer festival with her family, enjoying the fireworks contest at the beach, also she often visited the zoo. Her brother Ichirō was the first person who taught her how to fight and defend herself, then, at some point in her early youth, she also started to study martial arts at GAMOU Fighting Gym, winning several kid championships and making friend with both the owner's daughter Gamo-chan and her childhood friend Yoshi. In the juvenile judo circuits she became known and feared as "The Tororoimo of Kaze Junior High" due to her flexibile joints and slippery style. Somewhat at this point of her life, she met Shikki and fought her during a championship, defeating her with ease and gaining her silent respect due to this.

However, after in the very first dojo she attended Nagatoro met Orihara - a girl with whom she never really get along despite the latter started to consider her a friend - everything changed since the initially talentless Orihara, that at first was always defeated by her, started training harder and harder until one day she managed to overwhelm Nagatoro in a single move, unintentionally causing her to lose all her passion and ultimately quit. The event was very traumatic to the girl and apparently shattered her self-esteem leading Nagatoro to become convinced that Orihara is someone she "simply couldn't beat".

After beginning to attend Kazehaya High School, Nagatoro, Gamo-chan and Yoshi were all placed in the same class, 1-C where they became friend with Sakura, who eventually joined their group.

Ever since they reach teenhood, her friend Yoshi tried to be the matchmaker for Nagatoro, introducing her to various boys, however she cannot bring herself to like any of them, never ever having a boyfriend nor any significant relationships with the opposite sex.

She joined the swimming club under their request and was given the president's old swimsuit, however she also often help the track and field club.

Meeting Senpai
One afternoon, while chatting with her friends on the school's library a second year student walked in trying to stay unnoticed, until the pages of a manga he drew fell on the floor and are immediately spotted by the girls who started to mercilessly criticize it and making fun on him. Nagatoro was the only one who remained after her friends left the room and then mock her Senpai, noticing the manga protagonist was a self-insert of him, but acted more manly than he could ever do. Crushed, the boy started to cry and she gently wiped his tears away with her handkerchief, cheerfully apologizing for having bullied him and run away.

The following day she approached the boy in the school corridor right out of the art club room, discovering he was it's only member. He gave her back her handkerchief and told her to go away but, instead she proposed model for him as an apology for having bullied him the previous day, sexily told him that if he made a good paint of her she would give him a "reward". However, due to the final result being more similar to a sketch since he was too embarrassed to look at her for more than a second, she started to mock him again and reduced him to tears for the second time.

The following day Nagatoro met Senpai on the street and started to tease him once more, then she asked him why he never got mad with her, despite the fact she did lot of messed up things to him, to whom he answered that he doesn't dislike talking with her. After this, she formally introduced to him, despite preventing him for doing the same, saying that she preferred to call him just "Senpai". After this, the two formed a weird friendship-like relationship and quickly became inseparable. Nagatoro started hanging out in the art club room daily after class in one occasion she mocked the manga Senpai read calling it "lewd" and causing an incident after which they both tumble down and her right hand accidentally landed on the boy's groin, embarrassing them both, while in another occasion she tried to re-enact a vampire movie they saw on TV and bite his neck, pinning Senpai to the ground but backing off at the last time due to the garlic in his breath from the yakisoba he previously ate.

Despite her usual coldness toward boys, Nagatoro visibly started to enjoy Senpai's company sexily teasing him at every occasion, even for the simplest thing, like washing their hands together. She also kept forcing him to draw her, even bringing a sofa in the art club room so she could do many different poses; due to Senpai having difficulties in drawing her, after a while, Nagatoro felt sleepy and shifted position one more time to lie down for a moment, remembering him he would get a reward if he painted her well enough. After she woke up, the girl discovered he managed to paint her and, keeping her promise, kissed him on the cheek.

Over time she even start to get concerned about hurting his feelings and tried to help Senpai respond to his disses by improvising a manzai sketch (Japanese cabaret) to make a retort to her insults. However Nagatoro went too far insulting him and he eventually get offended. Realizing her error, Nagatoro apologized and tried to cheer him up, telling him to hit her shoulder to make a comeback, however as he did it, due to the tears in his eyes and the anger, he accidentally hit Nagatoro's chest instead of the shoulder, making them both embarrassed but resolving the tension.

Introducing Senpai to her friends
One day Nagatoro invited Senpai to have lunch with her, Yoshi and Gamo-chan at the school cafeteria, introducing him as his boyfriend. Getting jealous, her two friends started to tease him and calling him names, causing the girl to get angry and eventually taking his defenses, prompting Senpai to admit he wasn't actually her boyfriend. The two girls burst out laughing at the futility of his statement and apologizing to him, admitting he was a very funny guy. Afterwards, Nagatoro has a "nipple-poke game" with Senpai using as a prize a special ticket that would have forced the loser to do anything the winner would have ordered; she won and told him that one day, once he forgotten about it, she would have used the ticket, warning him to be prepared.

The day nagatoro pierced again her lobe to prevent it for completely heal, she pranked him suggesting to pierce his ear too so they could have a matching pair of earrings, but instead barely poked his ear, asking if he was disappointed that she hadn’t "made a hole in his body". Also, she found out he has inserted a character with her likeness in his manga, being quite amused about it, and, when the students have started to wear the summer uniform, thus allowing her to see how skinny Senpai's arms were, she offered to train him. However due to his laziness, Senpai stated that he would have do a training only if it was possible to do it without moving, prompting Nagatoro to order him to get on all four and riding him like a horse for muscle training until two girls passed by the corridor and saw them making her very self-aware, leading her to jump off while Senpai collapsed to the ground.

Sometime later, noticing his hair has gotten too long, Nagatoro proposed to Senpai to cut them like she often did for her brother, however after she exited the art club room to borrow a comb, Yoshi and Gamo-chan entered and, seeing the electric razor that Nagatoro left behind, decide to try shave Senpai, however he opposed to them, shouting that he already promised to Nagatoro he would have his hair cut by her. In that moment she went back, causing her friends to run off, then Nagatoro cut Senpai's hair and they shared a sweet moment as he thanked her.

The following day, after being caught in a storm Nagatoro and Senpai seeks refuge under a gazebo in the park, then after it get worse, the girl asked him if he wanted to stop by at her house, where they clean off, changed clothes, took a cup of tea and enjoyed at afternoon playing video games together. While departing, Nagatoro told Senpai that they should did it again sometime.

After her friends pranked Senpai by making him touch Gamo-chan's breasts and Nagatoro saw it, she was utterly mortified but Senpai quickly explained the girl has actually stuffed anpan under her shirt, causing Nagatoro to cheer up and laugh it off as an hilarious prank. Relieved, the girl offered him to try pinching her upper arm, revealing only after he did it that the upper arm's texture was the same of boobs.

Summer break
At the beginning of summer, Nagatoro and Senpai went to a place she knew to get some shaved ice, however they discovered a massive crowd of people lined in front of it. The girl stubbornly decided that they would have waited their turn in line, prompting Senpai to protect her twice as from people who ogled at her due to her uniform getting transparent and from getting an heatstroke, eventually he dragged her out of the line to a vending machine and bought her some water to prevent her for getting dehydrated, impressing and deeply moving the girl, who o buy some convenience store ice cream just like Senpai previously told her to do, composed an haiku to celebrate the moment and offered an embarrassed Senpai to feed him.

The day before summer break began, Nagatoro asked Senpai to exchange mail contacts and was overjoyed after he accepted. When he told her there was nothing special in having his line ID, she sweeten up and tenderly saying that she believed otherwise. Then, after parting ways, she sent him some cat-sticker for being a "pervert" as he was about to drink from the water bottle from which Nagatoro stole him some sips.

The next day, Nagatoro invited Senpai to join her and her friends at the beach for the following afternoon. After arriving, she became quite jealous that the boy briefly ogled her friends more buxom physiques, and was visibly upset when, after Gamo-chan proposed to go swim all together, he refused, taking a sketchbook out of his bag to begin drawing. Then, albeit unable to fully enjoy it due to feeling bad about Senpai, Nagatoro has a swimming competition with her friend/rival, who also tried to cheer her up saying that if he didn't wanted to swim they couldn't force him. However, Nagatoro went to him and asked what was going on, prompting him to confess he couldn't swim and had huge fear of getting sunburned. The girl offered him the 50+ sunscreen, stripped him and said she would rub it on him, embarrassed Senpai replied that that would have been something boyfriend and girlfriend would do, pointing out that they weren't. Feeling irrationally offended by his words, Nagatoro pinned him to the ground and started to rub the lotion on him with her foot in retaliation. However both of her friend soon joined her in giving Senpai said treatment, prompting Nagatoro to stop after using the whole bottle and fully covering him on sunscreen. Then, the whole group ended up having a good time, making another swimming competition together, playing with sand and eating ramen at the beachside. The next morning, she asked Senpai at the phone how did he felt about having come to the beach with them and he admitted that it was actually fun.

The night of the summer festival, Nagatoro was forced to go to school due to having a special club practice; thus she informed her friends about it. That evening, however, after she finished her duties and was in the locker room with the club president, she apologized for having make her stay up until that late and asked if she planned to go at the festival with someone. Nagatoro blushed and thought to Senpai, prior to receiving a notification at her smartphone and saw that Gamo-chan has sent her a picture of her and Yoshi at the festival with Senpai. The plan set by her friend to made her jealous, thus prompting her to come, worked and Nagatoro ran from the swimming club's lockers to the temple where Senpai was held "prisoner" by her friends, lying that she finished earlier and only came there since she was free. Wanting to tease her friend/rival about her feelings for Senpai, Gamo-chan told her that if she wanted to free him she had to defeat them in some games at the festival. Competitive as always, Nagatoro accepted the challenge but not without insisting that she didn't care for Senpai at all. They began with a shooting game, splitting for a 2 vs 2 team battle in which the winner would have been the pair who managed to get the most decent prizes. Paired in the same team with Senpai, Nagatoro asked him why he was at the festival, to which he lied that he wanted a change of pace, Nagatoro replied asking if he was waiting for her to invite him, making him blush as it was the truth. The girl then pointed out that if there was a place he wanted to go with someone, he had to invite that person himself. After playing some other games, Nagatoro and Senpai managed to win a big Squiddy plushe and, knowing Yoshi collected them, Nagatoro gave it to her, thus "bribing" her and winning the contest. Gamo-chan immediately freed Senpai from the collar and left together with Yoshi in order to let the pair enjoy some time alone at the festival. Then, Nagatoro and Senpai decided to wander around the festival together, eating takoyaki and cotton candy, after a while Nagatoro expressed out loud her thought that if felt like being on a date, before quickly correcting herself adding she was just joking. Nagatoro suggested though that she could play pretend and gave him a taste of what dating feel like, so she asked if he wanted to try hold hands, before he could answer the fireworks started causing the girl to getting anxious as she loved their town's fireworks, despite Senpai admitting he only saw them once in primary school. Since they found the fireworks contest on the beach too crowded, Senpai grab her by the hand to prevent that she was caught between the crowd due to her short stature, and drag her to a spot in the woods from which they had a great view on the fireworks. Feeling uncomfortable for the romantic situation, Nagatoro started teasing Senpai asking what was he thinking bringing a girl on a dark spot like that and calling him a "perverted virgin". Realizing from his past experience that Nagatoro got embarrassed pretty easily herself, Senpai decided to gave her a taste of her own medicine asking her what she meant for "lewd stuff". Too ashamed to answer, Nagatoro started to stutter something regarding embracing and kissing, claiming that anyway there wasn't a chance he could do something like that, causing Senpai to ask her if she believe she could. Despite stating she totally could, after the fireworks lighten the place, showing lot of couples kissing all around them, they both got embarrassed and ran away to see the fireworks quietly in a more hidden place.

New semester
The first day of the new semester, after class, Nagatoro sat at the gazebo in the park close to her home chatting with Gamo-chan, Yoshi and Sakura when they were approached by a couple of boys who started to hitting on them, she tried to ignore them annoyed as always, until Senpai, who was looking at them from a distance too embarrassed to come any closer, was greeted by Gamo-chan who ask him to sit with them, giving Senpai enough confidence to propose Nagatoro to walk home with him. The girl accepted and was soon joined by her friends, who then leave the two guys behind; after Senpai asked if it was okay for the girls not staying with them, they told him those two were "annoying" and started to jokingly tease him. All five of them smiled heartily.

The next day, while passing by the corridor, Nagatoro saw her friends dragging Senpai inside their classroom closing the door behind and eavesdropped from behind it, hearing Sakura intended to "jerk off" the boy she gets jealous and storms into the room angered only to discovered she misunderstood the situation and she was trying to "yank off" a splinter that went inside his finger; frustrated yet too prideful to admit it, she simply took the tweezers from Sakura and yanked off Senpai's splinter herself as her friends applauded.

Few days after this, while they were walking home together, Nagatoro challenged Senpai to a game of 'rock, paper, scissors' in which the loser would have to carry the winner's luggage until they reached the following crossroads. After losing the first match a sulking Nagatoro found herself forced to carry Senpai's bag, then, winning the second the boy carried hers and, after she won the third the girl forced him to give her a piggy ride; however while doing it, Senpai's hands started to slip to Nagatoro's upper thigh, causing the girl to jump off and, with minimal explanation, run away with a nervous and terrified expression on her face.

After seeing Senpai's poor performance at the school marathon, Nagatoro playfully told him that, as his kōhai, she was embarrassed for him, however when he replied that "all he can do was draw" she was greatly bothered, getting so motivated and angered by his lack of self confidence to begin personally train him. The following day, despite being a weekend, she forced the introverted boy to join her in a marathon training, turning him on due to her attire and causing him to stare at her sweaty and barely covered behind while running their 5Km route, thus he augmented his pace in order to stay in front of Nagatoro and don't risk to be accused of perverted thoughts. However, after covering half of the route, Senpai collapsed and asked to stop, causing Nagatoro to insult him to provoke him, going as far as to slap her own butt telling him to try to catch her if he was angry. Senpai reprised the run angrily, causing the girl to smile and sweetly told him to do his best.

Sometime after this, while hanging out in the art class room with him, Nagatoro criticized Senpai for never exiting his comfort zone nor taking some risks, suggesting for example that instead of drinking every day the same standard flavored orange juice, he should try taking the "mystery juice" in the vending machine close to the school, however he noticed that Nagatoro herself has that same orange juice, prompting him to tell her that she was the same as him regarding taking risks. Sulking, the girl replied that she usually didn't drink that kind of juice, so it was risky enough for her. After taking a few sips, Nagatoro sat back on the sofa while Senpai continued drawing, then he took a sip for his orange juice and placed the bottle on the same stool over which Nagatoro placed hers. The collision made both bottles fall but Senpai was quick to getting them back, however he couldn't recognize anymore which one was his and which Nagatoro's. Noticing the girl was silently watching, and not wanting to be mocked for an accidental indirect kiss, Senpai tried to watch her reaction as he moved his hands from a bottle to the other but Nagatoro had an impassive expression. It was unclear if she saw which one was her bottle or was unable to tell it so, feeling thirsty, he decided to take the risk drinking from one of them. Seeing this, the girl blushed and, without saying anything, drank from the other bottle. If they actually do indirectly kissed was left ambiguous.

After the school cafeteria where Nagatoro and her friends usually chat has been invaded by a group of boys they deemed as "loud and annoying" the girls turned to the teachers but they told 'em to solve it on their own, prompting them to decide to hang out in the art club room instead, while Sakura is working on seducing them one by one in order to sow seeds of jealousy in the group and making it collapse as they all began to compete for her attention. After they explained the situation to Senpai, complaining on how all men are driven primarily by their sexual desires, Gamo-chan teased Nagatoro stating that Senpai instead doesn't have any libido, prompting the girl to made a bet with her friend that if she find a lewd book hidden in the room by him she would have proved he was actually a quiet pervert. Nagatoro turned the room upside down, Senpai yelled he's not hiding anything, to which both Yoshi and Gamo-chan agreed despite Nagatoro stating that he was losing his cool since she was about to find his porn. After a while he began to feel bad about Nagatoro losing the bet since she was, in a certain way, doing it for him and taking advantage of a moment of distraction from the girls, he sneaked inside the prep room, where he hid Yagamirin Tarou's "Paradise Harem", took it and allow Nagatoro to find it. The girl was overjoyed and started to playfully tease him, while her friends watched the scene perplexed.

One day, Nagatoro noticed Senpai is having a bento and he explained it was due to not having lots of money that month, however, seeing how messed up it is, she began to make fun of him. That evening, Nagatoro prepared a homemade bento with the intention to share it with him the next day and confide it to Gamo-chan; however her plan backfired since, feeling offended for her comments the previous day, Senpai has prepared an exceptionally well-made bento in order to teach Nagatoro a lesson. Slightly upset of this, even after both of her friends exchanged a piece of their lunch with a bite of Senpai's bento, explaining her how amazingly good it was, Nagatoro pridefully refused to do it as well and started to eat her bento. Wanting to help her friend, Gamo-chan suggested Senpai to swap a dish with Nagatoro, yet they are both too stubborn to ask for the swap. In order to resolve the stalemate, Gamo-chan revealed that she was surprised he made chicken that spicy as he wasn't good with spicy food while Nagatoro loved it, prompting the boy to admit it was actually too spicy for him, this granted Nagatoro the chance to ask for a swap making it seem like she was doing a favor to him; she gave Senpai the homemade dish she knew was his favorite (despite it contained spicy mustard too) while Nagatoro ate Senpai's chicken and has a "foodgasm" just like her friends had.

After Sakura began getting stalked by one of the many boys who compete for her attention and asked Senpai to pretend to be her boyfriend in order to discouraged him from continuing. Jealous, Nagatoro tried to convince her friend to change her mind, calling Senpai "dangerous as a vermin", but she was ignored and caused the opposite effect convincing Senpai to play along with the gal's plan. The following day, being Saturday, Senpai and Sakura went on their fake date while Nagatoro, Gamo-chan and Yoshi followed them recording everything with their smartphones. Gamo-chan teased Nagatoro saying it was like an anime plot when "two people went on a fake date but real feeling start to blossom" thus getting her friend frustrated despite firmly refusing to admit it. Before Senpai and Sakura could get too close, Nagatoro captured the stalker and forced him to promise that he would never do it again. Having put an end to the charade, the girl began to mock Senpai for ruining "his first date" by telling him that it was probably too soon for him to do such things, however he smiled and agreed.

While they were all on the art club room, Nagatoro told Gamo-chan and Yoshi how she scared Senpai with the idea of repeat one year and be in their same class, thus making him frantically study to pass the exam. Amused the three girls started to toy with the idea of what would they do if he failed the grade two times thus making them "his senpais". However, as the boy started to fear the three girls would have enslaved him if that ever happened, Sakura reassured Senpai that it won't happen because other than Nagatoro both she and the other two girls will have to take supplementary lessons due to their low academic results. Embarrassed, both Gamo-chan and Yoshi asked Senpai to tutor them, making Nagatoro jealous.

Culture Festival
Overhearing that Senpai has been dumped by a guy to which he has asked to model for his exhibition at the school's Culture Festival, Nagatoro proposed to be his model instead, if he begged her. Nagatoro's intention to be prayed, however, faded as the boy refused the offer since he considered too hard to draw the female figure, especially hers. Due to the girl insistence, Senpai eventually decided to tell her he would have used her as a model only if she posed cosplaying in her infamous Nekotoro version, sure that she would have refused. The following week, much to his surprise, an utterly ashamed Nagatoro shown herself into the art club room wearing a perfect Nekotoro costume that she asked the handicrafts club to made her and insisted for him to say something getting really mad when he simply complimented how the outfit was well made.

Later, posing for him, Nagatoro teases Senpai on making her look sexy while her friends laughed at his embarrassment. Then, the girls started to chat regarding what they planned to do with their clubs or class for the Cultural Festival, with Nagatoro explaining she would have helped her club in organizing a yakisoba stand as per it's 20 years tradition. When she asked to Senpai what would be the art club exhibition he stared into space and began remembering the previous year; then, after Nagatoro woke him up from his memories, he answered that he would probably make an art display, causing the girls to said it would be boring and that they would give him an hand to fire it pu a little. Nagatoro ironically suggested it would be fun to have games in which torturing him or a kitty-themed maid café while Sakura suggested a cross-dressing café featuring Senpai dressed like a female maid, which a secretly amused Nagatoro refused, fearing the boy could get too much attention. In that exact moment, Senpai heard some familiar footsteps and asked the girls to hid in the prep room right before the President entered with a stern expression. While the President told Senpai she was disappointed for him inviting people and being rowdy, eavesdropping on their conversation hidden in the prep room, Sakura, Yoshi and especially Gamo-chan all teased Nagatoro saying that beautiful older girl is probably Senpai's ex. After the President informed Senpai that she was thinking about disbanding the club leaving him unable to reply, Nagatoro came out of the prep room with her friends and face the girl herself accusing her of being selfish and unreasonable as she was the one who abandoned the club. The President dismissed said accuse stating that if the only club member lacked motivation there were no reason for the club to continue, thus angering Nagatoro who finally lashed out making her feelings for Senpai transpiring and yelling that even by himself he has always worked really damn hard. Hearing this, the President suggested that Senpai held his own art display independently from the club and, if he defeated hers in the school's popularity contest she would have rescinded the club's disbandment. Although Senpai was not very confident about it, Nagatoro immediately accepted the challenge in his stead.

After the President left Nagatoro started to do a mocking impression of her with her friends, prompting Senpai to stop them saying that they were the ones at fault and that they had zero chances of victory against her. To cheer him up the four girls all offered to lend him an hand, suggesting to make his display a "kitty-kitty cosplay art café", but Senpai began praising the President's talent telling them of the many awards she won and that the previous year the art club display ranked 6th in the popularity contest on over 50-60 exhibits. Hearing this all four of the girls realized Senpai has quite a crush for the President, much to Nagatoro dismay; however after Gamo-chan asked how could it be that an high schooler's painting ranked that high in a popularity contest Senpai shown them the President's picture that gathered so much attention: a nude self-portrait. The shocked girls all realized how it could have been that popular, prompting Nagatoro to said it was a lewd pornographic painting and asking Senpai what it was his opinion, getting really mad when he answered he thought it was amazing explaining the several reason why he believed it. Gamo-chan told everything the boy has to do was painting something equally amazing, to which Nagatoro replied she would have modeled for him, even wearing a swimsuit if he really begged her. Senpai replied that he wasn't confident enough to being able to match the President's talent, while Gamo-chan pointed out he was actually already losing a lot in term of "material of work", referring the President's massive boobs compared with Nagatoro's petite chest.

Nagatoro sulk at Gamo-chan for having dissed her, despite the latter explaining it wasn't her intention since she only meant a big-breasted model usually gathered a bigger crowd, also she told her that being a little cute is nothing paragoned to a body like the President's, however Senpai claimed that both Nagatoro and the President are charming in their own way, finally prompting Gamo-chan to apologize to her friend. Heartened, the girl asked Senpai how she preferred to paint her, however he told her that he didn't want to use her as his model since if he dragged her into that match and lose it would be embarrassing for her. Offended, Nagatoro stormed off the room, soon followed by her friends, all of whom lightly scolded him for hurting Nagatoro's feelings. The next day, Nagatoro entered the room to visit Senpai and, seeing the President half-naked with him (she was doing another nude self-portrait), she run away deeply saddened. Senpai chase after Nagatoro but was unsure regarding what to tell her and how, so he stay silent thus, when a pair of her classmates reach them she told them that he was a stalker and run away again. Senpai chased her for the second time and after they reached an impasse, she climbed a tree in order not to listen to the boy, causing him to yell at her from below begging her to be his model. Blushing, yet remaining mad, Nagatoro told him that he can ask the President to be his model if she rather her, thus getting distracted and falling from the tree right on top of him, since he tried to catch her. Quickly awakening from the impact, Senpai told her he didn't wanted to draw the President but her; Nagatoro, pleased but determined to kept the tough façade, asked him why he finally admitted that Nagatoro was the most stimulating person for him. In the moment the two classmate of Nagatoro they previously run into passed by and, seeing them one on top of the other giggled, making them both embarrassed.

Over the next days, Senpai started doing some sketches of Nagatoro, causing her to mock him for how fishy it looked; although she often asked him if it isn't better to do something more daring even going as far as joking about fighting lewd with lewd and thus taking her clothes off, he answered her that he wanted to try creating a slice-of-life on Nagatoro. Later, while Senpai admitted to her that he didn't knew what would he do if he lose the match and thus the art club, Nagatoro said she would have felt sorry for him and might helped him joining the swimming club with her, making him slightly blush despite declaring he wouldn't have done it as he had no skills nor interest in said sport. Walking home that afternoon, Nagatoro admitted she didn't understand the sense of his slice-of-life work, to which Senpai answered it's show "how cute she was". Realizing what he had said, the boy blushed as vividly as Nagatoro then, to make the tension disappear, she started to tease him over the term he used.

After he shown his painting of Nagatoro's slice-of-life to Yoshi, Sakura and Gamo-chan, they were all impressed by them and the latter told him is like he looked at her as a lover, embarrassing both Nagatoro and Senpai. Then, Gamo-chan suggested to sneak a peek at the President's work, convincing all the gang to do it except for Senpai; however after seeing it the girls came back shocked and Nagatoro fainted. Thus, Gamo-chan and Sakura planned to be "cunning" as the President and began to make a plan to fight back against her new work and, although Senpai claimed they didn't needed to do anything weird as it was a problem between Nagatoro and him, the girls thrown him out of the room telling they would do their best to ready her up. Then they choreographed a dance featuring Nagatoro in her cat costume, together with Yoshi and Sakura wearing mascot costumes, the "I'll Bully You Dance" and uploaded it on YouTube making it the talk of the school also selling some related straps, that became amazingly popular.

The day of the Cultural Festival, the girls entered Senpai's display and Nagatoro performed said dance, prompting people who have seen the video began gathering all around the display to be willingly bullied by the so-called "Toro-Cat". A boy complimented the paintings and asked her out, making Senpai jealous, then, although she seemed not interested as always, under her friends pressures she started to act with the boy like she always do with Senpai, causing more and more people to came in order to be treated in the same way. As the hours passed lots of people also went to see the President's new nude self-portrait, however Senpai's exhibition seemed to gathered more interest. However, after a pair of girls went to compliment Senpai for what an exceptional artist he was Nagatoro get visibly jealous.

At 12:10 Gamo-chan made Senpai and Nagatoro to go get some food so that they can spent some time together. When Nagatoro try o make an excuse saying she couldn't just leave the exhibition as she was sulking at Senpai, Gamo-chan replied that Yoshi and Sakura could work harder to fill the void. While going to get food with Senpai, Nagatoro tried to act cool and asked him if he wasn't happy for having girls fawning over him, however she ultimately couldn't continue the charade showing how mad she really was for it. To cheer her up, Senpai told her that all the compliments he received were thanks to her for being his model, making her blush, smile again and sweeten up despite all her attempt to stay mad at him. She then asked him to treat her to something to eat if he really was thankful, joking about buying 100 takoyaki and 100 yakisoba to bring them home and freeze them so to have them everyday. The two shared a meal cheerfully and then returned to the exhibition, discovering that the President's display had been shut down by the student council as they has given her permission only depending on what they would have seen on the actual day.

While the President is escorted away due to her painting being deemed as "too immoral for a school" by the student council, Nagatoro and Gamo-chan forced her to admit they have won the match as she lose due to disqualification and, after exulting with Yoshi and Sakura, in order to further humiliate her the girls forced the President to wear a skimpy bunny suit and sell their straps all over the school. After getting a sold out the girls allowed her to go and Nagatoro told her friends she would have taken a little walk around too, although they all cheerfully realized she was actually planning to go to Senpai. Reaching him right at the moment in which the shameless President was about to strip in front of Senpai and prevent her from doing it, prompting her to lie saying she was just joking despite Nagatoro didn't believed her at all. Then looking at Senpai's paintings of Nagatoro, she told him that there was "love" in it, thus making both Nagatoro and Senpai blush. Then she smiled and tore the disbandment form into pieces overjoying the two. In that moment the speaker announced that the live concert would have been started at 4pm and Nagatoro told Senpai she was there for that, indirectly asking him if he wanted to go with her; he accepted and was immediately dragged to the auditorium.

The following day, after they met on the street and Senpai confessed that he didn't knew how to approach her and say "hello", Nagatoro offered to give him a lecture about how approaching people. However her various pattern of greetings consisted in painful pats on the neck, tripping, pricking and even kicking until, finally, she hugged him from behind. Feeling Nagatoro's boobs against his beck and her breath on his neck Senpai got quite embarrassed, while the girl licked her lips and told him to do the same with her or she would spread to school the rumor that she hugged him and he got an erection. Later, while they have reprised to walk quietly, a distracted Senpai stumbled and hugged her, groping her right breast in the process. Blushing, Nagatoro hitted him powerfully and made him fall against Gamo-chan and Yoshi who were coming from the alley in that moment and greeted themselves normally, proving every form of greetings illustrated by Nagatoro were lies.

Sometimes later, Nagatoro and her friends invited Senpai to a sushi all you can eat restaurant to have a Culture Festival wrap up party with them since they sincerely intended to celebrate him and the success they had. After all of her friends offered Senpai special recipe that they composed or improvised, feeling jealous, Nagatoro tried to make her own special dish, overdoing it and taking half of the rao for a tarako gunkan and placing in it half of the milt from a shirako gunkan to create, in her words: "a miraculous meeting between and milt that could get someone's stomach pregnant". This shocked the whole gang, prompting even Yoshi to describe it as "disgusting". While her friends scolded Nagatoro for playing with food like that, however, feeling bad for her Senpai decided to try it, finding it surprisingly "delicious".

Date at the zoo
Few days after the end of the Culture Festival, Nagatoro approached the art club room while the President was exiting it and eavesdropped only her last words, understanding that she just ordered Senpai to "ejaculate". Suspicious, she peered into the room and, seeing he has two zoo tickets, she get excited and immediately check on her phone some recommended advises for a zoo date, then, feigning indifference, she entered the room and sat on the sofa. After Senpai managed to take courage and asked her if she liked animals, Nagatoro eagerly answered positively, then he asked her if she likes to draw, to which the girl replied she only did it in class, admitting she was a terrible artist and would like for him to teach her. Finally he managed to ask her if she wanted to go at the zoo with him the following sunday, which the girl accept smiling heartily. On that weekend, a dressed up Nagatoro met with Senpai at the zoo and, after the boy gave her a sketchbook, she realized her misunderstanding, getting her a little upset, implying that she expected something sexy from the date. At the zoo, the girl's attention was absorbed by Koujirou-kun the red panda and, after he finally stood up, she tried to call Senpai, pouting after noticing he was too absorbed by his sketches to enjoy their "date". The boy immediately apologized guessing she was getting bored and told her they can simply walk around if she preferred it, however Nagatoro replied that she was fine and would play along with it, asking him to "take her hand and teach her everything" in return. Despite some initial embarrassment and the girl teasing him all the time, Senpai accepted and, taking Nagatoro by the hand, show her how to drew the general outline of a subject. The pair spent the afternoon drawing various animals and, although Senpai doesn't notice, the girl actually looked him with a sweet expression every now and then. Later they relaxed at the bar and, confronting their sketches, Nagatoro felt like hers were quite bad, however the boy reassured her that they were actually good for a beginner, yet, noticing Senpai's drawing were almost alive, she asked him what was her secret to which he replied is simply having an interest or liking what you draw (in order not to said "love"). Thinking about all the time he drew her, Nagatoro smile. Then, she went on the restroom leaving him alone for a bit. After she returned, the girl saw Senpai stood up to defend her drawing from a pair of schoolmates who were also there, so she scolded them for criticizing her work and harassing Senpai, making them apologize out of fear and then leaving. Senpai thanked her for saving him and she jokingly mocked his weakness thus making him admitting that it was really pathetic of him being bailed out by a kōhai. However having actually saw him yell at the two to take her defenses and she was deeply impressed prompting her to smile and reply that level was just about right for him. As it was getting late, Senpai proposed Nagatoro to draw her favorite animal as their last one. She chose the cage with the sloth and, as they began drawing she positioned way behind the boy, then, after they finished the girl revealed that she was actually drawing him: a "five-toed sloth, so slothful and weak that risk extinction and with such a weak presence that can rarely be noticed". Although annoyed, he noticed it was actually very well drawn and realistic, blushing a little while remembering that the secret of drawing is "love". Seeing him staring silently into the void, Nagatoro asked Senpai what he was looking at and, as he refused to answer, she started to tease him again.

Coming of winter
One day of the following week, Nagatoro was chatting in the cafeteria with Senpai and her friends about a group of boys from session 1-A having been suspended for drinking alcohol at the party after the Culture Festival. Although the girls criticized those boys for having been "stupid and cocky", Senpai can't help but believe they were habitual alcohol drinker too; he didn't expressed those thought out loud but they guessed it and scolded him for being rude. Then Nagatoro imagined what would have Senpai looked like drinking in a not so far off future, resulting in the group's hilarity. To cheer him up Nagatoro told him she would have brought him to a nice grown-up bar to drink together when they became adults, yet Senpai claimed he didn't plan to drink alcohol ever as he didn't understand what was so fun in staggering around drunk. The following day, the girl transformed the art club room into a bar-like setting and ordered insistently that he made an order, until he told her to give him what she recommended out of annoyance. The girl then made a Bloody Mary leaving out the vodka. The boy commented that is then just tomato juice, to which she told him to just drink it and, as he did it, he found it really good, then Nagatoro sit with him and told him to enjoy their "adult drink" yet, after a few sips, she got drunk due to having eaten whisky bonbons chocolate as snacks, which make him smile reflecting that maybe when they grew up, drinking together could be fun.

After the weather started to get cooler, Nagatoro bought a pair of black tights to keep her legs warm and, after Senpai let out a sigh commenting that it can't be helped, realizing only afterward that he talked his thoughts out loud, she asked him to put the tights on her in order to prove he is not "obsessed with her bare legs". To further embarrass him, Nagatoro asked Senpai to do it smoothly, however, as despite this, the boy managed to ascend from Nagatoro's foot to her calf right up to her thigh, getting closer to her inner thigh and thus her groin, she freaked out and told him that was enough, proceeding in putting on the rest herself with the excuse that his hands were "way too lewd". After she finished putting on her tights Nagatoro asked Senpai how do she looked and, when he complimented her, she asked if he had a fetish for it.

After discovering Senpai with the first volume of a shoujo manga she also read (whose plot mirrored that of their story), she admitted that she felt a connection to the female protagonist and found hilarious how she reduced the male lead to tears, yet when Senpai claimed that what was depicted in the manga was nothing compared to what "a certain someone" does to him, Nagatoro felt offended and shows him some rows from the following chapters in order to prove she was not as mean as the female lead. Senpai remained shocking for seeing that, in one of the last chapter published online the heroine forced the male protagonist to lick her loafer after he accidentally spilled some water on it, Nagatoro joked on doing the same if he ever spilled water on hers. However while she messed around the water actually spill on it, causing Senpai to bend down and, as the girl blushed and became nervous over the idea of him actually licking her foot, cleaning it with an handkerchief. Later, walking home on a cold day, they decided to eat ice-cream inside a warm place, however as he got a little aroused for seeing her lick it and she noticed how he was staring at her, Nagatoro messed up with him first proposing a bite of her cone and then asking one of his to make him admit he was worried for the possible indirect kiss, however while doing this, she stumbled and, although Senpai managed to catch her before she fell to the ground, in the heat of the gesture their ice-cream toppings come into contact, mixing an thus causing them to sat back and proceed licking their ice-creams, very much aware that it's an indirect kiss.

During the school wide marathon, Nagatoro and her friends approached Senpai and proposed him a race. He tried to refuse saying he'd rather run at his own pace but the group try to persuade him telling that it could be like in the fable of "The Tortoise and the Hare", thus they won't let their guard down, to which he joke that they're more like cats than hares. Right at that time they saw the President overrun them all dressed in her bunny suit since cosplaying was allowed. Thus, the girls get motivated into "beating the hare" and, after Senpai wished them good luck as the President was one of her class top athlete, Nagatoro reminded him that is the tortoise who should beat the hare, thus meaning he was the one who must race her. Although he was skeptical, the girls supported him saying they would have poured their power on him, forming a line to push one another in order to booster his speed, however after arriving a crosswalk Nagatoro and Senpai are separated from the other girls due to a traffic light. After Gamo-chan, Yoshi and Sakura told them that they should keep going and would definitely catch up with them, Nagatoro and Senpai proceed noticing that they should be around the halfway point. The girl noticed and complimented how much Senpai had trained for the race, though not without mocking his style of run. Then, the boy sprain his ankle and explain to a worried Nagatoro that he twisted it the previous day while running, prompting her to take him under her arm in order not to let him behind, saying they would have kept going until they reach the school. Nagatoro compared their situation to a war movie scene, when two soldier gets separated from their unit, one of them is wounded and the other refused to leave him, saying they would go home together. After a while, noticing how in pain Senpai really is, she asked him to get on her back. Embarrassed the boy told her that she don't need to feel responsible for his ankle, to which she replied that they'll go faster that way stating that she would be able to carry him with ease, eventually managing to convince him. Despite feeling a little guilty for riding a girl's back, Senpai described Nagatoro as amazing for managing to carry him with such a small body. Then however he noticed that she was actually struggling and asked her to stop stating that he doesn't want to go on if there's even a possibility that she might get hurt. As Nagatoro blushed, Gamo-chan reached them, complimenting his line, and, together with Yoshi and Sakura, help carrying Senpai in a sort of human cart quoting that "a tortoise might be slow, but if you give it a booster, then it can fly". Racing all together in said formation, they managed to reach the President however, as she was still faster than them, Gamo-chan told Yoshi to run in front of them using her almost superhuman speed to act as a windbreak and increasing their speed, narrowly managing to beat the President, albeit getting disqualified by the teachers because of their formation.

First name arc
Sometime after this, after having taken a nap in the art class room, Nagatoro received a text from Sakura and went to her friends in order to have a "dazzling girl talk", however while exiting the room she accidentally forgot her smartphone behind. The girl took a tomato juice along the way and reached Sakura and two classmates and start to talk about one of them having recently started dating someone in the baseball club. The conversation quickly switch over what types of boys each of them are into and, when they urged the reluctant Nagatoro to answer said question too, she answered that her type of boy is simply "someone who's fun to be with". Then, Nagatoro noticed her smartphone was missing and Sakura suggested she probably left it in "the club room", causing their classmates to ask if the reason she attended that place so much lately was a boy; both Nagatoro and Senpai - who had previously hid inside the closet - blushed and the latter panicked causing a noise that drag the girl's attention to it. When Nagatoro went opening the closet she found Senpai inside and, despite at first visibly mad at him, the girl invented and excuse to distract Sakura and her classmates dragging Senpai out of her class. Despite mocking him for how creepy he was hiding in the closet, she sweetly thank him for bringing her the smartphone and then asked if he heard what she said. Ashamed, Senpai replied he had no idea what she was talking about and run off, leaving her red faced.

The following day, Nagatoro get a flu and, despite recovering quickly, she had to take a leave from school for two days. While at home, she asked her sister to get her a pudding, then went to sleep and, after awakening, entered the kitchen yawning, with messy hair and a comfy pj, blushing in embarrassment after discovering that Senpai was there to visit her.

Embarrassed, Nagatoro immediately went to dress and do her hairs, scolding Senpai for not having called nor warned her before coming to her house, to which he replied that he sent her a text, although she yelled back at him that she was sleeping. Then Nagatoro's sister prepared her a special marlowe pudding with fruit and cream to calm her down, saying that they should all sit and chat a little. However feeling ashamed, Nagatoro asked Senpai to came to her room and forbid her sister from entering. While in her room, Nagatoro blushed a little and thanked Senpai for coming to visit her, to which the embarrassed boy replied he simply wanted to bring her printout. Then, they started eating pudding and, at some point, the girl teased him by offering to feed him. Due to being alone with her, Senpai decided to play along with it and opened his mouth, right in that moment Nagatoro's sister enter and caught them in said compromising position commenting the boy does indeed seem interested in "every little detail" of her little sister. Blushing vividly, Nagatoro sent her sister out of her room and then asked Senpai what does she meant by her last sentence.

After Nagatoro's sister's statement an awkward silence descended on Senpai and Nagatoro, prompting the boy to trying to leave right after finishing his pudding, however Nagatoro prevented him from doing it asking him to play a match with a videogame with her like they did the last time he went to her home. While playing the game, Senpai noticed that Nagatoro have probably practiced with it, since she has gotten better. Then, the girl asked him what did he talked about with her sister, worried that he asked her about her secrets while she was sleeping, however he quickly reassured that he wouldn't have poked his nose into someone else's business without asking. Hearing this, after winning a match, Nagatoro offered to reveal him one of her secrets of his choice if he managed to defeat her. At first Senpai pretended not to be interested, slightly offending Nagatoro, then he accepted said offert saying he was simply "taking her up on that". After the match started, Nagatoro playfully teased him asking if the secret he wanted to know was her measurements or something "even lewder", to which Senpai replied he would have liked to know her first name, leaving her speechless.

A bit embarrassed after realizing that she never told her name to Senpai, Nagatoro blushed but then tried to act nonchalantly saying that she didn't mind to tell it to him but provocatively asking him why he wanted to know it. The boy lied telling her that it was simply because it would be easier to call her, to which she replied that how she called her didn't really mattered, however, while they were talking the game's time runs out resulting in Nagatoro's loss. The girl played it coolly - despite being visibly happy of the circumstances - and, using their previous bet as an excuse, get ready to tell her name to Senpai; however the boy he stopped her at the last minute saying that he didn't want to know her name due to having won a game but rather after finding the courage to asking it to her directly. Both Nagatoro and Senpai blushed and agreed on waiting for that day to come. Right at that moment, Nagatoro's sister stormed into the room calling her "Hayase" and bringing the photo album of her primary school years in order to show it to Senpai. Regardless of Nagatoro yelling her to getting out of her room, her sister continued to show embarrassing pictures of "little Hayase" to Senpai. That evening, after they said goodbye to one another, Nagatoro told Senpai that she would have been back to school the following day and suggested him to "prepare himself", causing the boy to smile heartily.

The following morning, Senpai and Nagatoro met while walking to school. At first it's awkward to both of them, then the girl start pulling him by the sleeve, showing on her smartphone that is at the first place on a ranking of moves girls can do to instantly excite men. Senpai stated that it didn't excite him at all, prompting the girl to sulk and try repeatedly. Annoyed, the boy decided to grab Nagatoro's sleeve to prevent her from keep going, but he didn't get the timing right, ending up to grab her hand instead. Right at that moment Gamo-chan, Yoshi and Sakura appeared, commenting on how bold they were for holding hands in public. Embarrassed, Nagatoro quickly tried to deny that they were holding hands, saying to her friends that she was merely trying a judo move on him, without sounding believable to anyone.

Few days later since she didn't find him at the art club, Nagatoro called Senpai wondering why he wasn't there and, after discovering he catch the flu and was all by himself at home due to his parents jobs, she felt deeply sorry for him, especially knowing that she was the one who spread it to him, thus she "wrung his address out of the President", reached his home and - despite firmly denying being worried for him - became very protective, put him on bed, took his temperature using her own forehead, placed a wet blanket over his head and stayed at his side nursing him the whole afternoon, even calling her family to inform that she would have been at home later than usual due to wanting to watch over him. After the boy's mother texted him that she wouldn't make it home until very late in the evening, Nagatoro cook Senpai some porridge and feed it directly to him, causing the boy to start to hallucinate about being married to the girl whom, caught in the euphoria, he thanked for assisting him by calling her "Hayase", which leave her utterly shocked and, deep down, very pleased, thus leading her to try to get rid of her own discomfort by teasing the boy and daring him to repeat it; however since he was still too dazed to react in any manner and fell asleep, Nagatoro simply watch over him asking again to repeat her name, even going so far as to ask him please. Sweeten up by the situation, she asked the sleeping boy if it would be okay for him that she kissed him and, taking his obvious silence as a yes, leaned forward to do it; right at that moment Senpai's mother came back home.

Embarrassed, the girl run out of Senpai's room and ran into the woman on the living room, being too nervous to say anything Nagatoro leave the woman's home with minimal explanation without even introducing and asking forgiveness for her intrusion. The following morning, when Senpai and Nagatoro meet on their way to school there was a moment of mutual embarrassment, then the boy thanked her for what she did and Nagatoro replied it was nothing since he did the same for her, right before starting to kick him as a "punishment" for "having been so cocky", referencing having called her by her given name.

Christmas
Few days later, while she was hanging out in the art club room, Senpai asked her to be his model. At first the girl pretended to be busy in order to be prayed to, but in the end she accepted and asked him what pose he wanted her to take, leading him to tell her to assume the one in which she felt "more natural". Hearing so, Nagatoro assumed a series of stance from muay thai, boxing, capoeira and a fourth one that she assumed without thinking but seemingly made her uncomfortable. After seeing the latter, Senpai deemed it as the one on which she was "more natural" and asked her to pose in that stance, which the girl eventually accept blushing a little. While the painting was being done, Senpai and Nagatoro exchanged several glances, the first asking himself what kind of stance was that while the latter staring at him with sweetness. After finishing it, Senpai asked Nagatoro about the stance, leading the embarrassed girl to choke him in a submission move stating it was her own personal martial art style in a clear attempt not to answer him. Right in that moment Yoshi, Sakura and Gamo-chan entered the room and, while the first two simply told playfully Senpai to surrender in order to get freed from Nagatoro's move, seeing the painting Gamo-chan got quite emotional, saying heartwhelmingly to Nagatoro that "it has been a while since the last time" and asking with evident nostalgia if she wanted to give it another try. Senpai asked what they were talking about, but Nagatoro stormed out of the room saying she won't tell him. That afternoon, while going back to home, Senpai noticed that Nagatoro seemed a little down, and she confirmed that the "cold windy winter days disturbed her heart". Noticing that seeing the girl depressed made him feel weird too, he found the courage to invite her to a restaurant specialized in wagyu and croquette and treat her to a meal. Nagatoro simply took a special croquette, which she describe as "super juicy" and, while walking home, in order to tease the boy as well as prove him it was better than the regular one he took, dared him to take a bite from hers. Senpai ultimately choose to simply grab a piece with his fingers and ate it, resulting in Nagatoro making fun of him anyway telling him that, differently from that time in which they took ice cream together, it wouldn't have been an indirect kiss. Then she took a bite from his croquette nonchalantly. Later, while almost home, Senpai finally asked her if there was something that worried her, prompting Nagatoro to admit she was feeling a little down due to not knowing what to write on her future plan survey form, so she was planning to leaving it white, resulting in Senpai telling her it won't be good.

The following day, during snack time, Nagatoro meekly asked her sister for advice regarding what to buy to someone for Christmas and, after teasing her a little with embarrassing questions about if it was intended to be for "someone special", her older sister ultimately suggested to take something "he" would use everyday.

Christmas Eve, right after the principal speech to the students, they all get ready to came back home and Nagatoro approached Senpai asking him if he would have been alone on Christmas, however the girl's friends interrupted them and drag them both into the library, where an argument had ensue: Gamo-chan was planning to invite everyone at the karaoke and is upset because Sakura and Rabi-chan had other plans with boys; thus leaving only Yoshi and Nekoba to join her. As a fight ensue between the "girls with boys" and the "girls without boys" and they start bickering, Senpai noticed that Nagatoro had a present in her bag, and in turn she noticed the boy had one too, leading them to exchange an embarrassed glance. After a few minutes Gamo-chan asked Nagatoro if she would have came to the karaoke, leading Nekoba to ask her if she and Senpai were dating or not, which caused both of them to blush. Out of embarrassment, Nagatoro quickly denied it saying she simply like to toy with the boy, thus Gamo-chan told both her and the boy to join them at the karaoke, however the latter refused making up an excuse to remain alone with Nagatoro and saying he had to take something in the art club room; understanding what he was doing, the girl seized the opportunity and quickly joined him copying his excuse and dragging him out of the room saying she would have met with the gang later. Once arrived in the art club room, Senpai and Nagatoro pretend to take some objects to fuel their mutual lie while try to find the right words to exchange their respective gifts; however before they can do it the President enter the room completely naked as she wanted to "feel its atmosphere on her skin" being her last time in it before graduation. Angered, Nagatoro called her an "horny bunny" and told her to "graduate already", then the President asked if they were on a tryst, causing both of them to blush and storm out of the room right as the school's broadcast informed the students to leave the institute as quickly as possible. In order not to be caught by professor Yamaguchi - who's very strict about the rules - the duo hid in the nurse's office. Once again they tried to exchange their gifts, but at the last minute freaked out due to hearing Sakura making out with her date on one of the bed. Having managed to sneak away remaining unnoticed by the two lovers, Senpai and Nagatoro went to the rooftop hoping to get some privacy, only to find out dozen of other couples on it watching the sunset. Downcast by all those setbacks, the two decided to simply go home, however, after seeing Nagatoro shiver, Senpai found the courage to give her his Christmas gift, which is revealed to be a muffler. Overjoyed, the girl gave him her own gift in return: a scarf. Later, while they walk back home, Nagatoro jumped happily and joked on the fact that they got the same gift to each other.

New Year
On New Year's Eve, she called Senpai and manipulated him into visiting the Ishido Shrine the following day. Once he visited said place, Nagatoro revealed she picked up a part-time job there as a due to a desire to wear their traditional  and. Sulking due to not receiving compliments for her look from the boy, she started to insult him as always, getting scolded by him from saying certain things while dressed in such a sacred attire. Then, Nagatoro accompanied him to wash his hand and rinse his mouth in order to purify his body as per rite, before taking him to take an and bragging about hers. After realizing she did all of that just to show off, since her fortune slip read "great fortune", Senpai open his discovering it read "misfortune". Then more visitors came to the shrine, prompting Senpai to leave in order not to be in-between the slightly disappointed girl's job. Later, Nagatoro complained to a colleague that life never went the way someone wanted, just at that moment Senpai appeared, asked for an amulet and managed to say that he would have waited for her at the end of her shift. Although she made fun of the boy calling him a "stalker", Nagatoro was overjoyed and reached for him after twenty minutes asking him what he planned to do. Senpai managed to said that he wished to visit the shrin with her, realizing right at that moment that the place was a matchmaking shrine. Promptly Nagatoro began teasing him that he hoped the two of them would have made "a good couple", leading Senpai to deny it out of embarrassment and reply that if he would have "just hypothetically" wished to ask her out one day he shouldn't have prayed to a god but rather work at himself. Moved, the girl wished for him to work hard at it, then they went praying at the shrine together. While leaving the place together, Nagatoro asked Senpai what he wished for, to which he answered his family's health, leading the girl to reply her wish was to become his bride, right before adding she was "just kidding".

Few days later Nagatoro entered the art club room, saw a box of contact lenses on the table and teased a mortified Senpai asking if he intended to "change his four eyes look in order to look hot", after the boy replied that he simply wanted to give contact lenses a try, Nagatoro dared him to wear them right at that moment, prompting him to admit he was too scared to put them in his eyes. Due to having previously helped her brother putting his, Nagatoro offered to help Senpai put the lenses and, albeit a little skeptical at first, the boy eventually accepted and sit at her side while the girl crawled on his lap to place the lenses inside his eyes. Nevertheless of Senpai's embarrassment, Nagatoro put both lenses in and, after he asked her how does he looked, the latter replied that he was fine but without his glasses couldn't do "his trick", then she put on Senpai's glasses and mimicked his signature gesture of adjusting them by the bridge while embarrassed. Seeing Nagatoro with his glasses, Senpai blushed, causing the girl to ask him if he thought that she looked cute in glasses.

Somewhat later, during a ski trip with their school, Senpai and his classmates remain impressed by Nagatoro, Gamo-chan, Yoshi and Sakura's talent as they managed effortlessy to ski down the pro course, leading the boy to daydream about skiing together with her down that slope. After she spotted him in the crowd, Nagatoro invited Senpai to ski with her, leading two of his classmates to assume they were dating. Due to Senpai's clumsiness, the girl offered to give him some training, however he didn't managed to gain any result, which result in him getting sad about weighing her down. That night, at the hotel, Senpai and his classmates saw Nagatoro and Sakura in the night skiing group; once again, she invited him to ski with her, however he refused saying he was tired, to which Nagatoro simply walk away telling him to "train a bit more". Later she saved Senpai at the last minute from a collision course with a guy who was bragging with his girlfriend, having her take a video while skiing on one leg, furiously scold both the boy and his girlfriend, even complimenting with him for how he skied to save the child, leading him to ask her for additional tutoring. Nagatoro sweetly smiled and told him to stop looking at his own feet and instead, try looking at her. The next morning, she watched as Senpai's classmates ask him to show what he learned for "his private instructor", however, after he eventually accept, all he managed to do is fall on the snow causing the whole gang to burst out laughing.

Judo Tournament
Sometime later, with the school year nearing its end, she observed from a window in the corridor Senpai performin poorly during a judo class in the school gym, however she quickly escape when the boy's teacher began distributing flyers about the school's judo tournament to all of his student. After having been told by Gamo-chan to visit her family's gym that Saturday, Senpai went there while the former was boxing with Nagatoro, thus distracting the her and leading to her being knocked out with a single punch. Embarassed, the girl accused him to having followed her there calling him a stalker, only to be scolded by Gamo-chan not to "rough up" her costumers, thus prompting Nagatoro to reply she invited him only to prank her. Later, Senpai told Nagatoro that he performed badly at the school's last judo tournament, thus asking her to teach him judo, Nagatoro blushed vividly and then sweeten up, shyly accepting his offer. After the two have changed into and done a little, Gamo-chan went to her lunch break with the other trainers leaving the pair alone and leading Nagatoro to propose  to a frightened Senpai. Then, Nagatoro quickly overpowered Senpai pinning him to the ground, where he found himself unable to get free from her grip and is forced to surrender to her calling her "too heavy" for him to move, thus offending Nagatoro, who angrily explained that even a light little girl like her could pin someone to the ground by controlling her own center of gravity. Later, Nagatoro has a second match with Gamo-chan while Senpai watched. Afterwards, while walking back home together, Senpai finally asked Nagatoro if she did judo, to which she replied that she used to practice it in the past but stopped as she realised that there are "people she simply couldn't beat". Seeing her so sad, after parting her goodbye, Senpai yelled to Nagatoro that he thought her moves were "really beautiful" leading her to blush and smile at the same time before quickly run off. Few days later the school's judo tournament began and while Senpai and his classmates watch, Nagatoro won her first round against a girl named Yamashita while Gamo-chan faced Olympic judo team candidate Orihara, being effortlessly overpowered. Afterward, the girl commented with her friend that Nagatoro would have to face Orihara in the following round, referencing their past together. Despite Orihara being friendly and telling Nagatoro she hoped to have "another exciting match" with her, the latter leaves the judo hall disconsolate and was joined by Senpai who tried to comfort her. This promped Nagatoro to explain to him what happened between her and Orihara in the past, concluding that she didn't even feel like it was worth to fight anymore. Hearing that, Senpai scolded Nagatoro, telling her that this behaviour doesn't feel like her, thus upsetting her and leading her to told him not to talk like if he knew her, to which he replied quoting what the girl herself once told to him about not knowing what would happen until trying pointing out that even if her advercary is an Olympic candidate Nagatoro herself was quite strong. Blushing, the girl told him that she would have given it a try if he won at least one match; also teasing the boy that in that case she would have also kissed him. Later during his match, while cheered by both of his classmates, Sakura, Gamo-chan and Yoshi, Senpai managed to remember the stuff Nagatoro had taught him, putting up a good fight and eventually leading the girl to gleefully cheer for him, out of herfelf for the joy, which surprised both, the boy, her friends and Nagatoro herself. Eventually the boy lose his match by points but is complimented by both his opponent and his classmates; thus despite the his defeat, Nagatoro decided to keep her promise anyway and fight against Orihara. Although the two girls were equal in terms of skills, Orihara was given as favorite and thus everyone in the hall except for Nagatoro's friends started to cheer for her, which leaded Senpai to cheer for Nagatoro as she previously did for him. Despite blushing for it, the girl was quite pleased and gained enough confidence to slam Orihara on the floor getting a waza-ari, but eventually she lose by points just like Senpai. The match however does restored Nagatoro's passion for judo, leading her to shaking Orihara's hand after losing and promising her that she would have definitely "get her" next time. Walking home with Senpai, Nagatoro tought back at it and asked him to give her a kiss as a prize when she would have managed to if defeated Orihara, causing the boy to blush telling her not to tease him, to which she replied she wasn't, just a moment before running home with a smile on her face.

Second year of high school
After the new school year officially begun, she joined the judo club alongside Gamo-chan and then stormed into the art club room, which Senpai has taken over exposing a poster to recruit new members, while doing a painting in order to calm down since he was trying to downplay what she told him about wanting to have a kiss from him as a mere joke, Nagatoro complimented him for being a third year and ask if he still want her to be his model. The boy quickly accept and thus Nagatoro change into her swimsuit explaining that she hid it into the prep room in order to be always ready for a sketch. Senpai started to draw Nagatoro despite the latter kept teasing him on how red he was and gawking at her. During their first ten minutes pause from the drawing, Nagatoro sweetly revealed to Senpai that she finally joined the judo club, since she really wanted to receive a kiss from him. Seeing the boy's embarrassed reaction, she get frustrated and eventually asked him directly if he wanted to kiss her or not. Before Senpai can answer the question however, a new girl very similar to the former President entered the room, acting as if she knew the boy, calling him "Hachioji-senpai" and saying she wanted to join the art club. After having introduced Sunomiya and Nagatoro to one another, the girl get unnerved both due to the kōhai huge respect for Senpai and to be introduced only by her surname, grade and sometimes harsh manners, while Sunomiya, having heard the word "kiss" while in the hallway and seeing how they interacted with one another, asked if they were dating, which Senpai quickly denied much to Nagatoro's chagrin; then the boy explained to Sunomiya that sometimes Nagatoro modeled for him the previous year, but now she won't have that much time as she has club activity. Hearing this, Sunomiya realized that the club doesn't have any other member and thus she and Senpai would have been alone into the club room; despite Nagatoro tried to have the girl change her mind from joining the club telling her she would have catched Senpai's wriggly motions, Sunomiya stated to be able to find beauty into all eccentric things. Right at that moment Gamo-chan entered the room to go at judo practice with her friend and, seeing the girl saddened, teased her asking Senpai if he was "switching girl"; embarassed the boy explained her that he and Nagatoro were simply trying their best separately. Then Sunomiya reassured Nagatoro to leave Senpai in her care and stripped down saying she was ready to pose for him in the nude rather than a simple swimsuit. Outraged, Nagatoro told Sunomiya to put her clothes on again commenting that she's just like the former President, to which Senpai pointed out that she's actually the President's cousin. Later, after performing badly at practice Nagatoro and Gamo-chan chatted about how rusty they are due to not practicing it properly for years; the girls are soon joined by Orihara who told Gamo-chan not to worry that much as she need time being still a white belt, however she also pointed out that Nagatoro seemed distracted and asked her if something was wrong; Gamo-chan immediately told Orihara that Nagatoro was "worried her boyfriend would be stealed by a rival" now that she was buisy with club practice and can't hang out in his club room as much as before. Nagatoro was visibly embarrassed by the chat between her best friend and her rival; however, despite firmly denying the boy in question being her boyfriend, when Orihara suggested her to choose between love and judo, she indirectly state she would have both.

First date arc
That evening, after finishing practice, Nagatoro found Senpai outside the judo hall and asked if he was waiting for her, which the boy denied despite evidently doing it. Later, as they were walking home together, Nagatoro asked him if he felt alone without her around and admitted she wished there was a place in which they could have been together outside the club room. Hearing this, Senpai found the courage to ask her out on her day off, leaving Nagatoro speechless. When she asked Senpai what he meant and he replied it was only a question, she started to teas him by suggesting impossible places such as Mount Everest, the African Savannah, Antartica, the Jungle or Space. Discouraged, Senpai told her to forget about his question, leading the girl to say that even something closer might be good, pointing out that he should be the one to figure it out where. Puzzled, the boy suggested the cinema, which Nagatoro described as not bad but a bit too normal; then realizing how much she enjoyed places related to animals the boy clumsily followed said pattern suggesting at first the racetrack and then dog fighting. After they came to the fork and get ready to part ways to their respective houses, feeling down for not having managed to invite the girl, Senpai got a last idea and called back Nagatoro asking her out for a date at the aquarium on the following day off, which Nagatoro happily accepted. The morning after, an overjoyed Nagatoro slightly annoyed her friends with her behavior, going as far as to force Yoshi to sing a song with her. Then, after Gamo-chan suggested to visit Senpai due to having finished club practice earlier than usual, Nagatoro refused, causing Gamo-chan to panick and realize she was "leaving the best for last". The following day, as Nagatoro and Senpai met at the aquarium for their date, Gamo-chan, Yoshi, Sunomiya and her cousin all followed them, the first two to "protect Senpai's virginity" while the latter pair to "protect his romance". After boarding a train to go to the aquarium, Nagatoro noticed how nervous Senpai was and thus told him that that would have been just "practice" for him if he ever go on a real date, and that she would have graded with point everything he would have done. Later the pair saw the, , , and took a selfie together; however after seeing all of the other couples holding hands, Nagatoro started to ask Senpai if there wasn't something he should have done. While thinking, the boy noticed Gamo-chan, Yoshi and the Sunomiya cousins, so he took Nagatoro by the hand and drag her away, making the girl both blush and smile. After managing to escape their pursuers, Senpai went seeing the show with Nagatoro, shielding the latter from a splash of water. During the rest of their date, the girl teased him for all the minus point he had got, then, while watching the sunset at the beach, the girl told him he got 300 minus point, however due to grabbing her hand and shielding her from the splash, he then got 350 points getting a final score of 50. Nagatoro joyfully told Senpai that she would love to tag along again with him on a practice date; hearing this Senpai asked her if it was "practice" for her as well, to which Nagatoro replied that for her it was a real date the whole time. After this, Senpai told Nagatoro that he didn't considered their date mere practice either, leading the girl to suggest him doing something more "worthy of an actual date" giving him two options: hugging or kissing. Out of embarassement the boy choose hugging, however before they could even touch one another, Gamo-chan and Yoshi stormed the scene followed by the angered Sunomiya cousins, thus ruining the moment. Despite all four of the intruders told them to continue like they weren't there, out of shame Nagatoro lied saying she was merely practicing a judo move on the boy.

Out of anger for having got in the way of her date, Nagatoro sulk at both Gamo-chan and Yoshi, starting to ignore them both at school; however Sakura act as the peacemaker explaining the two girls didn't mean anything bad with their action and merely felt lonely as Nagatoro spent less and less time with them. Sweetened, Nagatoro forgave her friends and the four of them went to have lunch at the art club room. There, they discovered that Sunomiya was feeding Senpai a bento she made by herself as a way to apologize for what happened at the date. Upon hearing Sunomiya's plan to make bento for Senpai the whole week, Nagatoro got jealous and offered Senpai to prepare a bento for him the following day, however the boy refused stating that she would have morning training the following day and it would be too much trouble if she would have spent the evening cooking for him. Disheartened Nagatoro agreed, while all of the girls watch Senpai cooly due to having "made a mess again"; then Gamo-chan convinced him not to be stubborn and accept Nagatoro's offer. Hearing this, Senpai told Nagatoro that he would love to have her bento if she accept to have one from him, wich she joyfully accepted. The following morning Nagatoro woke up early in order to make bento for Senpai and has a videocall with Gamo-chan, Yoshi and Sakura telling them she planned to prepare a special with spicy curry in order to surprise him, however she accidentally burned it and thus got very upset. Right at that moment her older sister walked in, getting happily greeted by her friends despite the girl being slightly embarassed, and suggested her to make salmon filled instead, stating they're the base of every bento. Saddened by said suggestion, Nagatoro protested that it will have be too banal and won't have surprise him, yet she was convinced when her sister told her it will made her feel better to see him happy rather than surprised. After exchanging bento, both Senpai and Nagatoro are surprised by how good them were, the girl enjoyed especially a with lemon sauce that the boy admitted to have cooked thinking how much the training could exhaust her - as lemon is good to reduce fatigue - while Senpai praised it for how normal it was - since he expected something weird as always - and especially enjoyed the onigiri, thus making the girl as happy as her sister had expected. After finishing eating, Nagatoro and Senpai agreed to make bento to one another everyday by taking turns, and the girl joked it will make them seem like a newlywed couple.

Trouble at the Judo club arc
Thw following day, Nagatoro made bento for Senpai and herself as agreed and they ate it together, then the boy asked her if she wanted something particular for the day after since it would be his turn to cook, leading Nagatoro to tease him saying she would have loved to ate something that increase stamina; making fun of him after he wrongly guessed she meant something lewd rather than her club activity. After this, the girl went out of the room, saying she would have been busy after club activity (as her brother asked her to help him chose some clothes to buy) and thus they would have seen each other directly the following day. Later that day, walking home from school, Senpai saw Nagatoro talking to her brother and panicked, thinking that guy to be her ex; however he decide to approach them, greeting both casually and waiting for Nagatoro's reaction to decide if starting a conversation or run off. The girl greeted him happily and Senpai stop to talk with them. Before she could introduce him to Senpai, her brother stopped her and begin to inquire the boy about his relationship with her. Senpai, not knowing how to describe it, stated that the girl was his junior at school, prompting Ichirō to further asking him how much he knew about her, implying that he is aware of her sleeping posture and saw it several times, which lead Senpai to convince himself that the boy was her ex. Angered and embarrassed, Nagatoro attacked her brother, who demonstrated to be a superior fighter and told her not to forget that he taught her how to fight. Shocked at the developement, Senpai jumped in between them ordering him not to put Nagatoro in any more danger as, despite not knowing much about her, he knew what made her appy or sad. Pleased, Ichirō complimented Senpai and then leave the scene stating that it would have been gross to see his little sister "acting all flirty". Later, walking back home, Nagatoro guessed that Sempai was jealous due to believing her brother to be her ex-boyfriend and thus began teasing him. Few days later, during one of their usual lunches together Nagatoro admitted to Senpai that she actually tought having late practice every night to be hard but also fun since she aimed at receiving a kiss from him after defeating Orihara, making the boy blush. Later that evening, Nagatoro got challenged to a match by Shikki, who has a grudge with her for having left the sport and considered her to be "a quitter who half-assed her life"; during the match Shikki eventually hurt Nagatoro's right arm while Senpai was watching. Both, Gamo-chan and Orihara got worried due to Nagatoro having injuried her wrist in the match, however the latter dismissed it as nothing serious, while Shikki mocked her saying that getting injuried so easily meant she "didn't even tried". Angered by this, Senpai stormed into the room and confronted Shikki - pleasently surprising Gamo-chan, Orihara and Nagatoro herself - telling her that what she had said was wrong due to Nagatoro actualy trying very hard everyday; to which the girl got surprisingly meeker and shy. Seeing their friend in trouble, the other two girls of Shikki's group accused Senpai of being a stalker and spying on them, however Nagatoro intervened saying that the boy always waited for her when she had judo practice; later the girl let herself be taken to the infirmary and discovered that her wrist was broken and would have needed two weeks in order to fully recover. The following morning while walking to school together, Senpai apologized to Nagatoro for having intervened, but she instead thanked him saying he acted "kinda like a boyfriend"; then, just as the boy replied that he hoped Shikki's group won't take a revenge on Nagatoro, the trio appeared before them to apologize.

Shower arc
Being unable to go to judo practice due to her broken wrist, Nagatoro spent the saturday in the art club with Senpai and later decided to have basic training albeit sad to do it alone; which promped the boy to join her and have a run around the city together with her, passing in front of the judo hall to greet Orihara and Gamo-chan. After coming back to school, feeling cold due to the sweat, Nagatoro proposed Senpai to have a quick shower in her club's new showers room. There, the two "showered together" albeit separated from the thin wall that divided the boys' from the girls' section and had an heart-to-heart chat in which Senpai praised Nagatoro for how positively she faced her injury, leading her to admit she can do it only because he was there to cheer for her. Right at that moment the boy heard some voices and Shikki and her friends entered the showers room in wich the boy was discussing on how, after the place was renewed, the positions of the male's and female's room were swapped. Overhearing this, Senpai and Nagatoro realized they were into the wrong rooms, however despite at first the boy planned to stay hidden and sneak out after the trio left, Fujimin quickly detected "a boy scent" and angrily start looking for him with the other girl, while Shikki managed to hear Nagatoro's voice and, thinking she was having a shower where Senpai was hidden, approached said box in order to ask about her well-being and - opening it - found him. Understanding the situation quickly, Shikki cover for the boy and offer to help him sneaking outside by covering him with her body, however feeling bad at the idea of being that close to a girl while both half-naked, Senpai politely refused, prompting Shikki to promise she would have therefore hurried herself and her friends out of the showers in order to "be even" with Nagatoro but, right at that moment, more girls entered the shower room, forcing Shikki to enter the box with Senpai in order to keep him hidden and even open the shower head - thus starting showering - to avoid suspicion. Panicking, Nagatoro tried to reach for him but, being in the boy's section, as two guys enter the showers room she remained stuck as well, thus she overheard Shikki opening up about her feelings with Senpai and confessing her admired for his brevery and - indirectly - that, deep down, she missed "the old Nagatoro". The girl was quite moved from hearing this but the momnent was ruined when Senpai noticed that, due to the cramped space, Shikki's ass was rubbing against his; being unable to move back without opening the front door, the girl decided to turn the other side, ending up touching the boy's back with her bosom. Out of herself for the jelousy, Nagatoro jumped in the gap dividing the male and female shower boxes, squished herself into it and reached the other side, impressing Shikki with the flexibility she remembered and landing right in Senpai's arms after losing her grip. Later, Shikki exited the showers joining her friends and advising the pair to wait few more minutes before getting out of the showers; meanwhile Nagatoro teased Senpai for having felt up her naked body.

Field Trip arc
After talking with Senpai and discovering that their field trip in would have been together with the 3nd years with him being appointed as a group leader, Nagatoro informed her friends about it and started to hope being in his same group - albeit lying that she was only interested in bullying Senpai during the trip - then Sakura told her that every 2nd year student would have been free to choosen which group join. Due to Senpai's plan being boring and revolving around visiting Buddhist art locations, Nagatoro was the first one to sign up, followed by Gamo-chan, Yoshi and Sakura, out of simpathy for the boy and mutch for the joy of the only other applicants: his two male friends. However, after joining it, they also started to change the program radically: Nagatoro added a trip to Kyoto's aquarium, Gamo-chan added a visit to the base, Sakura an excursion to  and finally Yoshi a jaunt to  in order to feed deer. Senpai tried to convince the girls that there wouldn't be enough time for everything they wanted to do in the field trip's schedule, to which they asked him to remove some of the buddhist temples from the program, prompting the boy to oppose the idea and try to explain the beauty of each statue. Despite impressed by his passion, the girls confessed that they weren't intrested in the statues, prompting Takao, one of Senpai's friend, to suggest splitting the group so everyone would be happy. Albeit a bit saddened, Senpai agreed to said proposal, causing Nagatoro to get angry and storm out of the room. Later that night, Nagatoro had a videocall with her friends but was gloomy due to what happened, although Yoshi and Sakura tried to cheer her up and Gamo-chan told her not to pout due to this being her first and last opportunity to have a field trip with Senpai; prompting the girl to admit she felt confused about what to do. Then, she received a message from the boy, asking her to meet him outside of her house, where he gave her a new program he have made with Sunomiya's helf managing to decrease the amount of location to visit and have the afternoon of the second day as free time. Thus, he asked the girl if she wanted to go visiting Kyoto's aquarium with him, which she accepted right before offering to help him visit everyone's house to distribute the new program.

Webcomic
In the original webcomic, Hayase Nagatoro is often the only character seen by the reader due to the issues being mostly narrated by Hachioji senpai's point of view. In said iteration she is a malicious sadist whom evidently gains pleasure by hurting others, is violently abusive both physically and emotionally towards the male protagonist and rarely apologized to him or shows any signs of caring. At the beginning of the story she and Hachioji apparently knew each other for a while and, the day after having cheered for her at a sport competition, he invited her at the park in order to try asking her out; anticipating his intention, the girl started to insult him stating that he was unworthy of her affection and calling him "gross", "embarrassing", a "maggot", "human garbage", a "pig" and a "cockroach", until he finally confessed his love to her and asked her out, which she accepted telling him that she was doing it only to make him her own toy to play with and that she would have made fun in breaking him. Since then, Nagatoro and Hachioji started to date, however she kept torturing him, though he reached breaking point when the girl made him believe her brother Ichirō was her real boyfriend and she was merely toying with him; although eventually he takes her back. Nagatoro went as far as to proposing Hachioji that if he allowed her to use his butt as a sandbag for practicing kicks she would have go to the ocean with him. Despite promising to kick him very lightly, during said practice she got visibly aroused over the pain she was inflicting to him and started to hit with powerful muay thai kicks. However, when the last bow sent him to the ground motionless she got worried, apologized and told him to be prepared as she would "train him like an animal" when they would go to the ocean. Gradually, over the years, Nagatoro seemingly sweeten up a bit over Hachioji and on the Christmas night of her (presumably) last year before graduation, they went on a date, sharing a dinner at a ramen kiosk since she deemed more "christmassy" stuff "too lover-like" for them. Walking home they take two can of hot coffee while sitting on the park and talked about their dreams for the future before exchanging Christmas gift: Hachioji gave her a muffler while the girl, showing she wasn't completely changed, gave him a choker, saying it has been hard for her finding one of the right size and that she hoped it suits him properly.

Sometime after (or maybe a little before) this, the couple sat on a park bench looking at a dead cicada that was eaten by ants while they were eating ice lollys. Saying the bug came out the safety of underground, eventually facing death in order to do "lewd things", Nagatoro started to tease Hachioji senpai with some sexual remarks, before to showing him that the stick of her ice lolly has a sign that marked she has won another one as a prize and went to claim it alongside him.
