Hayase Nagatoro

"Will you keep running away from your weakness? Well, it's fun looking at someone as awful as you, but don't you want to get better? Do you want to stay awful like this? Awful Senpai ♥ Hey, hey; What will you do?"

- Nagatoro

Hayase Nagatoro (長瀞 早瀬) is one of the two main characters of the Don't Toy With Me, Miss Nagatoro manga series. She is a first year high school student who likes to tease and bully her Senpai, the other main character, although she secretly harbors feelings for him. Nagatoro is an energetic, athletic, popular and rather sadistic - but deep down very sweet - girl, often referred to as a "sadodere". She is part of a 'cool kids' clique together with her friends Gamo-chan, Yoshi and Sakura, and is a member of the swimming club, despite also having a liking for martial arts.

Her friends affictionally calls her with the pet name "Hayacchi" (ハヤっち), although this sometimes seems to annoy her.

Appearance
Nagatoro is an attractive, petite and short stature, first year high schooler with long, straight back hair pinned to the right side with a pair of white hair clips. She has brown skin with noticeable - though sometimes inconsistent - tan lines in the shape of her swimsuit, and large, expressive amber-maroon eyes. She has a metallic piercing on her upper right ear and both of her lobes are pierced, despite she rarely wears earrings. Compared to other characters, she is exceptionally small, although it has been hinted that she may have a late growth spurt, and has a lean, athletic, slender and very flexible physique with a modest bust size which she is often ashamed about despite being, considering her size and built, pretty average sized. Nagatoro is rarely seen without a sadistic, cocky smirk that often displays her very prominent canines, also, she has the tendency to widen the pupil of just an eye whenever she grins.

She typically wears her school uniform consisting of a white button up shirt (whose sleeves and collar she never keeps buttoned) and a navy blue skirt completed with a pair of sneakers and no socks. However, in summer she wears a short-sleeved shirt in her uniform, while in winter she is shown to wear a light brown sweater, black tights and loafers. She is also often seen wearing the light blue and white swimsuit of her club.

When not at school she usually sports a simple, practical or tomboyish choose of clothing unlike most of her friends; however she has proven to know how to relatively dress up if needed.

Personality
Nagatoro come off as energetic, cheerful, sarcastic, flirtatious, prone to fast-talking and moving individual with a sadistic streak. She likes to bully Senpai and finds joy in teasing him, however, although it appears that she just wants to torture him, it seems that there's more to it than that. In early chapters her antics could easily be described as "sadistic", frequently making Senpai cry, but soon she began to gain feelings for the boy and even apologized for "doing messed up stuff" to him, and asked him why he didn't stand up to her. Since then her bullying has mellowed out, and she even frequently acts outwardly friendly to Senpai, despite she keeps calling him "gross". As time passes, she is also occasionally defend Senpai's dignity and even shows to be very concern about Senpai getting angry at her as well as sincerely sorry while going too far. Nagatoro is very much a tsundere, despite denying her crush for Senpai and frequently mocking him, she is very possessive of him and doesn't tolerate her friends to bully him. Despite frequently belittling him, she does cares greatly for Senpai, being quite bothered when he says that "all he can do is draw" and getting motivated/angered enough by his lack of self confidence to begin personally training him. She also enjoys Senpai's company very much, but rarely outwardly shows it. Albeit when she invited him to the beach or to her house, she shows her intentions to enjoy it and wanting to do it again sometime. However she reacts with extreme flustered nervousness whenever he does the same, for example her face wearing an expression with extreme shock once senpai joked about failing a grade to spend more time with her, though she was angry when he did not fail, saying "Do you hate spending time with me that much..?".

She is very good friends with Yoshi, Sakura and especially Gamo-chan, whom could be considered her best friend, despite their similar and often competitive personalities sometimes put them at odds in a sort of friendly rivalry. Also, Gamo-chan loves to tease her in order to made Nagatoro admit her feelings for Senpai and bring them closer, causing pranks that sometimes led the two to resorted to near-physical violence despite they seemingly always made peace rather quickly every time they fight. Also, judging by their friends' reactions whenever Nagatoro and Gamo-chan butt heads, it's not wise to make them mad, implying that they both has a temper warranting fear.

Although very popular among boys, with several of them often attempting to hit on her or her friends, she always rejects them and showing herself bored, contrarian and standoffish while talking to them, even to the point of saying to Yoshi that "boys are boring", despite her obvious growing crush on Senpai. Her occasional coyness seems to be for Senpai alone. It's implied that Nagatoro uses casual rudeness towards Senpai in order to deflect her real intentions, taking three steps in with her suggestions ("let's wear matching yukatas for next year's festival"), and two out with her teasing ("I'm joking, that would be gross"), inching herself gradually closer to him, thus defusing the situation for the moment while leaving a kernel of hope for Senpai.

It's also shown that Nagatoro is a sweeter and more empathetic person than she lets on, and that she's more susceptible to Senpai's kindness than he realizes, even tenderly hinting to him - when he gives her his mail contact, all while telling her that he's not a person worth talking to - that his declarations of self-deprecation affect her too. Also, she has a deep sensitiveness toward the arts, whether is movies, paintings, dance, poetry or music. She seems to genuinely enjoy Senpai's art, frequently encouraging him to draw more and forcing him to use her as a model for his art. Though whether or not it's to train him to draw the female body, get him to draw her specifically, or is just an excuse to spend time and tease him more, is unknown. Nagatoro herself also occasionally draws.

Despite very frequently making sexual jokes to Senpai, mocking him for being a virgin and calling him a pervert, she is very nervous and sensitive about sexuality. For example: when Senpai was giving her a piggy back ride and his hand slipped to her upper thigh, she proceeded to jump off and ran away with minimal explanation and a nervous and terrified expression on her face, when Senpai meant to push her in the elbow and instead hit her breasts, she was very outwardly shocked and embarrassed for a couple of seconds, she had no problem in riding senpai like a horse for "muscle training" until when two unnamed girls saw it, making her very self-aware and causing her to immediately jump off, when she accidentally facetimed Senpai in the bath, she screamed in terror, when she and Senpai were trapped under a gazebo during the rain and he saw her drenched clothes and bra, she instantly blushed in frustration. Almost all those times, however, Nagatoro recovered after a couple of seconds and started again to accuse Senpai of grossness and sexual perversion, though he eventually realized that Nagatoro would be at a loss if he actually respond to her taunts and, romantically, Nagatoro is all bark and no bite, especially due to the fact that she can get as embarrassed as he does. The hypocritical humor of Nagatoro constantly teasing Senpai about being a virgin is that she's obviously as inexperienced with physical intimacy with the opposite sex as he is.

Nagatoro has a complex for her bust size and appears to be very self-conscious as well as jealous and possessive. In the beach chapter, when Gamo-chan and Yoshi were harassing Senpai with their large boobs, Nagatoro get frustrated, took off her clothes as well, stood in a bikini in front of him and demand Senpai to go buy drinks. She also was mortified when learning of Gamo-chan's prank to have Senpai "molest" her boobs - due to her jealously since she is the less buxom among her friends - but nervously laughed it off as an hilarious prank once learned that she had stuffed anpan in her breasts and Senpai never actually touched 'em. It also appears her teasing is somewhat just a front, a coping mechanism to mask her insecurities and inner nervousness.

She is also very athletic, loves the beach, and is a fantastic swimmer as well as having a huge passion and proficiency in various styles of martial arts; she shows her willingness to train Senpai after his poor performance at a marathon and easily outpaces him during their training run.

Apparently Nagatoro doesn't like shoes, as she almost never wears socks and is frequently barefoot when she can get away with it.

Early life
Hayase was born in, the second child of the Nagatoro family. She has a close relationship with her older brother, Ichirō, and 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 7-eleven; 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, at least until the end of primary school.

Nagatoro made friend with Gamo-chan and Yoshi around their middle school years, yet after beginning to attend Kazehaya High School, they were placed in different classes as her two friends were in 1-B while Nagatoro was in 1-C, there she became friend with Sakura, who then joined the rest of her 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, having no significant relationships with the opposite sex.

She joined the swimming club under their request and was given the president's old swimsuit.

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 didn'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 came, worked and Nagatoro run 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 she 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 peluches 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 pretending 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 run 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 came 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 get jealous and storm 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, simply took the tweezers from Sakura and yank 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 carried 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 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 risk, suggesting for example that instead of drinking every day the same standard flavoured 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 told her 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 sip, Nagatoro sat back on the sofa while Senpai continue 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 sew 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 prepare an 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 favourite (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 exibition 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 attentions. 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 facade, 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 diplay 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 exibition 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 intrest 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 classmates who were also there, so she scolded her 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 favourite 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 raws 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 skeptycal, 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 paragon their situation to a war movie scene, when two soldier gets separed 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 donesn'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, togheter with Yoshi and Sakura, help carrying Senpai in a sort of human cart quoting that "a turtoise 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, managing to easily beat the President, albeit getting disqualified by the teachers because of their formation.

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 muffer 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 on a park bench looking at a dead cicada that was eaten by ants while eating ice lolly. 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 wanting to take it alongside him.
