Naoto Hachiouji

Naoto Hachioji (八王子 直人) is one of the two main characters of the Don't Toy With Me, Miss Nagatoro manga series. He is a second year high school student who constantly gets teased by Nagatoro, the other main character, whom always refers to him only as "Senpai" (センパイ). He is an introvert, twitchy, loner, nerdy and shy aspiring artist, who tries to avoid social interaction with other people and doesn't seem to have any friends although, as the story progresses, he bonds with Gamo-chan, Yoshi, Sakura and Nagatoro herself, for whom he also harbors feelings. Senpai is the only remaining member of the art club beside the semi-retired President.

In the manga Senpai is unnamed and, In addition to the pet name used by Nagatoro, all the characters call him with a different nickname: to Gamo-chan he is "Paisen" (パイセン), to Yoshi he's "Sense" (センセ), while Sakura adds the suffix "-kun" (くん).

Appearance
Senpai is a very tall, gangling and angular build second year high schooler with a well-defined chin and curly, "fluff like" brown hair, often compared to a sheep's fleece. He has an extremely pale and delicate complexion - so much that he gets sunburnt easily - and sharp, twitching-prone brown eyes. He is short-sighted and always wears a pair of horn-rimmed glasses, although he can see somewhat decently even without them. Often described as a "bean sprout", Senpai is slender, incredibly weak and has a bony, dry, skinny, and very inflexible physique with his arms being so thin that could be contained in a girl's grip, but relatively defined pecs. Nagatoro frequently call him "gross", yet he is actually decently handsome and both the girl and her friends  has shown to find him quite attractive.

He typically wears his school uniform consisting of a white button up shirt (whose sleeves and collar he always keeps tightly buttoned) and black trousers completed with a pair of sneakers. However, in summer he wears a short-sleeved shirt in her uniform, while in winter he is shown to wear a cardigan.

When not at school he usually sports a plain, practical or classic choice of clothing.

Personality
Senpai was - at the beginning of the manga - an extremely frail, weak, introverted, shy and somewhat doormat individual with a bit of masochistic tendencies. Despite being pestered and bullied on a daily basis by Nagatoro, he never fought off any of her antics and put up with it, even after being put through a wide range of embarrassing situations. Having been bullied most of his life by lots of people, he adopted the philosophy that indifference is safety, thus he usually respond at bullying by trying to stay calm, avoiding his tormentors gaze, closing his heart, and letting it pass; doing so he developed a defense mechanism that made him unable to even remember the faces of the people who bullied him. Despite his emotional frailty, he apparently never cried before meeting Nagatoro, who succeeded in this twice. At first he took Nagatoro's bullying at face value, usually remaining deeply affected by her words and attempting to look away but, as the story progressed, her teasing mellowed out, and their relationship became outwardly friendly, despite she keeps calling him "gross". As time passes, he has become able to talk more naturally to her and in some occasions he has rebuked her and even teased her back.

Senpai tends to blush quite easily, and usually gets as red as a cherry in a significant part of his interactions with Nagatoro, as he is somewhat shy when it comes to girls. Fundamentally he is a sweet and kind young man in spite of his antisociality and, deep inside, he is more than aware of the fact that Nagatoro is so insistent in keeping him company, proving to be more than willing to dispense kindness towards Nagatoro regardless of how she treats him as well as becoming very determined and assertive when protecting her; an example of this is when he gets behind her in order to cover her back, as some guys were trying to ogle at her while in line due to her sweat having made her shirt transparent. Some other examples of this is when he intentionally grabbed her wrist, dragging her out of the line to a vending machine to save her from an heatstroke, or when dragging her out of a moving crowd when she risked being overwhelmed due to her short stature, and standing up for her when a couple of classmates criticized her drawings. Moreover, he is a real gentleman and, despite his not-so-well-hidden love for fanservice-heavy media, Senpai never attempts to do anything remotely lewd or rude towards either Nagatoro or her friends, not even once. This happens to be one of the reasons they enjoy his presence and feel comfortable around him, along with the perception that, unlike most of the boys that approach them, he is unpretentious and intellectual, if markedly wimpy and twitchy. They take a liking to him because, among other things, he's not a superfluous person like most of their boy classmates, and doesn't have the heart to be duplicitous, thus making him a better person than he thinks he is.

As the manga goes on, Senpai gradually establishes a good relationship with Nagatoro's clique of friends: Sakura is always very kind and respectful toward him, Yoshi found him quite amusing and has a fond for the fluffiness of his hair while Gamo-chan, despite often being rude to him, has actually shown to consider him a friend and that her taunts directed at him are meant to rouse Nagatoro as she's the couple's first supporter.

He is, overall, a very skilled artist, especially at drawing manga and runs his own fantasy manga series, where the main character is Siegfried, a skilled swordsman who's bad at getting on in the world that is actually a handsome-er and more manly self-insert of him, while the female lead is a beautiful knight named Elizabeth bears a striking resemblance to the President, even the events depicted in the story are mirroring his life as evidenced by the fact that at some point the two main characters have to part way as happened when she was forced to leave the club activities to go to cram school. Later, Senpai began to insert new characters like Nekotoro, a cat version of Nagatoro, a whip-holding bandit with the likeness of Gamo-chan and a furry-like bunny girl inspired to Yoshi.

Despite this, his self-esteem seems to be low as a consequence for suffering constant bullying throughout his whole life. He frequently said that "all he can do is draw", and even then he frequently stated he had trouble getting inspiration to draw, and thus ended up beating himself up inside about it, although he admits that he would like to be praised, but at the same time says that he could never get complimented by anyone because he has no talents. He began in the series unable to draw any female form at all due to nervousness, however, he eventually overcame such problem. One of the things Nagatoro prods him about the most is the fact that he tends to give up on things before even trying despite of the fact that the girl has displayed actual faith in him.

Senpai seems to enjoy shonen manga, typically those with large amounts of fan service, though he is very defensive about it when called out by Nagatoro, saying he only likes it for either the comedy, the action, or the art. Nagatoro describes him as a "quiet pervert" and, despite he often denies it, he has often shown to have frequent "lewd" thoughts, even to the point of imagining the President stark naked while she was talking to him about the nature, also he can't help admiring Nagatoro's occasional fanservice or that of her equally attractive friends.

Apparently, Senpai has some sort of social anxiety disorder, stating to not like crowded places due to the "normalfag aura" they had. In the beginning, he seemingly had no friends other than Nagatoro's clique, as shown by the fact that he never interacted with anyone else and has been shown to not having any other numbers in his phone, other than Nagatoro's, but later on his kouhai-senpai relationship with the President is revealed.

He doesn't enjoy many things in his life beside of playing video games, drawing, and spending time with Nagatoro and her friends. He doesn't like to go outside, or athletics or engaging in any form of physical activities, although he later starts to feel some joy in these activities due to his interactions with his kouhai, even admitting that "it's okay every once in a while".

He has the habit to adjusts his glasses by the bridge in reaction of his embarrasing.

Early life
Naoto was born on May 10 in, , an only child; both his parents are managers who often leave him alone due to their job, making him a. He grew up in a house in the suburbs right after a tunnel at the left of the first intersection past the public park; as a child he developed an interest for arts and began drawing.

An introverted and awkward individual, he was bullied since early childhood, eventually maturing a philosophy of indifference for safety: avoiding bullies' gaze, closing his heart, and let it pass; doing this he developed a defense mechanism that made him unable to even remember the faces of the people who bullied him. Despite being a victim of bullying for years, he never cried in front to anyone.

After beginning to attend Kazehaya High School, he was placed in class 1-B and joined the art club, developing a huge crush for its President; however, on the last day of the school's Cultural Festival, in which he helped her organize their club's display resulting in a huge success, she thanked him for having allowed her to have some good memories before having to go to cram school like all the second years, thus becoming unable to join club activities anymore and leaving the art club and its activities to him.

Since then he was left as the only club member.

Meeting Nagatoro
One afternoon, during his second year, walked into the library expecting to find it empty as usual, only to discover a group of four girls actually went there to chat. He sat quietly a few tables afar from them trying to finish his homework, 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. Only one of them remained after her friends left the room and, despite calling him her "Senpai", she started to mock him 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 he was approached in the school corridor right out of the art club room by the girl, 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 the girl 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 as Nagatoro, 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.

Once he watched her from afar as she took part at a date combined by a friend of hers, noticing how she acted coldly toward every other boys but him, realizing she kinda enjoy his company and likes to 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. Watching how cute and innocent she seemed while seeping, he finally managed to do an extremely accurate painting of her. At first Senpai felt proud of himself for finally managing to draw the human female figure, however he then started to feel embarrassed hoping Nagatoro never saw it, without realizing that the girl was actually already up and right behind him; keeping her promise, the girl kissed him on the cheek.

After said event, the introverted boy even began to have Freudian dreams about Nagatoro.

Over time Nagatoro 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 she 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.

Introduced to Nagatoro's friends
One day Senpai was invited by Nagatoro 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 Senpai 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", which he secretly was. Also, he ended up inserting a character with Nagatoro's likeness in his manga and she found out about it. Then, when the students have started to wear the summer uniform, thus allowing the girl 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, Senpai admitted that it was fun and Nagatoro told him that they should did it again sometime.

One day, Nagatoro's friends pranked Senpai by making him touch Gamo-chan's breasts and Nagatoro saw it. The girl was utterly mortified but Senpai quickly explained to her that Gamo-chan 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, when he told her there was nothing special in having his line ID, she sweeten up and tenderly saying that she believed otherwise, leaving him quite moved. 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; then, after Gamo-chan proposed to go swim all together, he refused, taking a sketchbook out of his bag to begin drawing. Later, 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.

As the night of the summer festival came closer, Senpai secretly wanted to invite Nagatoro - even imagining her in a yukata - but, lacking the courage to do it, he convinced himself that she would have probably forced him to go with her as she always did and that he could have accepted it saying it was out of annoyance. However as evening came, he didn't receive any call, disappointed he start to consider he should have the gut to invite her himself, but deemed it pointless since he believed Nagatoro was only interest in bullying him. Senpai ended up going at the festival alone, secretly hoping to meet the girl there. Saddened, after a while he decided to go back home, however he was approached by Gamo-chan and Yoshi, whom correctly guessed why he was there, informed him that she couldn't come to the festival because she had club practice, quickly caught him with a dog collar and forced him to accompany them around the festival, then Gamo-chan sent Nagatoro a picture of all three of them together. The plan set by the girl to made her friend jealous, thus prompting her to came, worked and Nagatoro run from the swimmin club's lockers to the temple where Senpai was held "prisoner", 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, while walking home, Senpai spotted Nagatoro under a gazebo in the park chatting with Gamo-chan, Yoshi and another girl he didn't know, Sakura. Watching them from a distance he felt them as very hard to approach and reasoned that they lived in completely different worlds, however when they were approached by a couple of boys who started to hitting on them, he came out from his hiding spot and 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 helping Sakura bringing some boxes to her classroom, Senpai got a splinter inside his finger and the gal offered to yank it off for him, while Gamo-chan and Yoshi immediately dragged him inside their classroom closing the door behind. Passing by the corridor, Nagatoro saw it and eavesdropped from behind the door, misunderstood that Sakura intended to "jerk off" the boy instead of "yank off" the splinter, get jealous and storm into the room angered only to discovered about her error; frustrated yet too prideful to admit it, Nagatoro 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 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, while Senpai was left puzzled.

After he made a poor performance at the school marathon, Senpai was approached by Nagatoro, who 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 "mistery 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 Nagatoro 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 decide to hang out in the art club room instead and, 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 insid 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 upsetted 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 franatically 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
After he was dumped by a guy to which he has asked to model for his exhibition at the school's Culture Festival, Nagatoro overheard it and proposed him 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, while 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 and, when Nagatoro 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 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 scolded Senpai for some rumors she heard about the club room having become a hangout for a bunch good-for-nothing, telling him was disappointed for him inviting people and being rowdy, she informed him that she was thinking about disbanding the club leaving him unable to reply. Then 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, Senpai went to the art club room in order to work on his painting, discovering that the President has taken possession of it in order to work on hers, leaving him the prep room. While he was doing a still life, the President approached him, wearing just a towel since she was doing another nude self-portrait, and told him it was a boring job since in order to be art a painting had to have love in it. Nagatoro entered the room to visit Senpai and, seeing the President half-naked with him, run away deeply saddened. The President ordered Senpai to chase her, saying that was also what art was about; which he immediately does. 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 Nagatoro 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 shows 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. Later, as the only members of the art club, Senpai and the President were both asked to help decorating the panels for the entrance of the Cultural Festival, then walking back together after having finished it, they talked about how their respective submission was coming along and the President said she won't hold back. Then, passing by the corridor they listen some voices of Nagatoro and her friends inside the art room and the President told him he mustn't eavesdrop on them and that regardless what they were planning the match was between the two of them, despite Senpai believed it doesn't seemed like that anymore. Right at that moment, a group of girls looked inside the room and sawing Nagatoro and her friends started to mumble about "Toro Cat" and some related straps, puzzling Senpai who, looking at a strap on the President's bag asked her about it prompting the latter to tell him it was very popular in her class in that period, prior to showing him it was actually a caricature of Nagatoro in her cat costume.

The day of the Cultural Festival, while the President has no problem in talking smoothly in front of the cameras when the school journal interview her, Senpai on the other hand felt uneasy and stammered, however right before the troupe finished their service, the girls entered Senpai's diplay and Nagatoro performed said dance, prompting people who have seen the video they have uploaded on YouTube to began gathering all around the display to be willingly bullied by the co-called "Toro Cat". A boy complimented the paintings and asked her out, making Senpai jealous, then, although she seemed not interest 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, 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 she went back to Senpai's exposition, where the boy suggested her to take off the bunny costume before risking other trouble with the student council. Nagatoro entered right at the moment in which the shameless girl was about to strip in front of Senpai, preventing her from doing it and prompting her to lie that she was just joking. Then looking at Senpai's paintings of Nagatoro, the President 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, Senpai confessed to Nagatoro that he didn't knew how to approach her and say "hello", thus she 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 hit 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, seeing Senpai seemingly having problem getting in the mood to do a good painting, the President gave him two tickets to the zoo so he could sketch while in the outdoors, ordering him to try invite the one she called the "cat girl", since if an outsider like her kept barging into the club she should at least draw something every now and then. Right as the President exited the room, Nagatoro approached it and, peering inside, saw him with the tickets, getting quite excited but then feigning indifference and entering the room to sat on the sofa. Initially too nervous about the idea of ​​inviting the girl and going at the zoo with her, Senpai remained in silence then, reminding Nagatoro's words at the summer festival, he took courage and asked her if she liked animals and after she answered she did he asked her if she likes to draw, to which Nagatoro replied she only did it in class. Senpai thought about saying she could teach her, however he dismissed that idea believing it would have sound too pushy, however it was the girl herself 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 they met at the zoo as programmed, although Nagatoro realized only then that it was for sketching. 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, while the girl was on the restroom, Senpai was approached by a schoolmate and his girlfriend; they recognize the boy and immediately started to mock him for drawing at the zoo. Senpai endured everything in silence as always until they criticized Nagatoro's drawing, then he lost his temper and yelled them both not to dare make fun of other people's hard work. Right at that moment Nagatoro came back and scolded the two for criticizing her drawing and harassing Senpai, making them apologize out of fear and then leaving. Senpai thanked Nagatoro 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 being deeply impressed by it, Nagatoro smiled, replying 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, Senpai was chatting in the cafeteria with Nagatoro 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", he 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, causing him to start imagining he was putting a radish into a plastic bag with a smooth motion in order not to blush too much; doing so, despite noting the girl's legs were way smoother, softer, firmer and suppler than a radish, he managed to ascend from Nagatoro's foot to her calf right up to her thigh, however as he got closer to her inner thigh and thus her groin Nagatoro 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 sorry), Nagatoro 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.

As the school wide marathon get closer, Senpai trained harder in order not to perform badly in front of Nagatoro, however during said training he accidentally twisted his ankle a little. The following day while running, he was soon approached by Nagatoro, Gamo-chan, Yoshi and Sakura who 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. Smiling, Senpai noticed how kind Nagatoro could be despite always messing with him, desribing her as a mystery. 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.

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, prompting Senpai to go looking for her to return it. Once he reached the first year's floor, Senpai realized he didn't knew what section Nagatoro is in, however a girl helped him asking who he was looking for and, due to not knowing her by surname, what was her first name. Embarrassed Senpai admitted to himself that he didn't knew, then however he remembered that her friends called her "Hayacchi", causing the girl to realize who she is and told him to look for her in section C. Along the way, Senpai saw Gamo-chan and Yoshi coming out of their class and wenting to the cafeteria for lunch. Not wanting to be caught, the boy hid in a closet inside section C, just in time for Sakura and Nagatoro to return in it alongside two classmates and starting 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". Eavesdropping that, Senpai suddently remember of all the fun times he and Nagatoro shared and remained speechless. Just 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 blushed and the latter panicked causing a noise that drag the girl's attention to the closet. When Nagatoro went opening it 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.

Two days after this, Senpai became worried of having offended Nagatoro because she stopped to came to the club room and hadn't texted him either. The boy went asking Yoshi and Gamo-chan about it, prompting the latter to reveal him that she simply got a cold but had recovered pretty quickly and would return to school the following day; then Gamo-chan asked Senpai if he knew where Nagatoro lived and when he replied affermatively, ask him to visit her and bring her some printout in her place. In the afternoon, Senpai went to Nagatoro's house and was approached by a young woman who, after mistaking him for a thief, introduced herself as Nagatoro's sister and invited him inside, offering him some snacks and revealing him that her little sister talked a lot about him. She also asked if there's anything he wanted to know about her, stating that she would reveal him whatever he want regarding her sister. Before Senpai could make his question, Nagatoro entered the kitchen yawning, with messy hair and a comfy pj, blushing in embarrassment after discovering that he was there.

Embarassed, 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 elses 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 embarassed 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 cooly - despite being visibly happy of the circustances - 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 embarassing 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 akward to both of them and the boy has difficulties in deciding wheter to calling her Hayase or not; then however 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 he caught a flu, took a day off from school and, due to his mother having an important business trip, he told her not to worry as it was "nothing serious" and convinced her to go remaining home alone. In the afternoon, Nagatoro called him wondering why he wasn't at the art club and, after discovering he catch the flu and was all by himself, she felt deeply sorry for him, 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, cooking him some porridge after his mother texted him that she wouldn't make it home until very late in the evening, feeding it directly to him and causing him to start to hallucinate about being married to the girl whom, caught in the euphoria, he thanked for assisting him by calling her "Hayase". Then he collapsed and fell asleep while the girl, nervous and deep down very pleased for what he said, got carried away by the situation and, after daring him to do it again, sweeten up and try to kiss him in his sleep; however, right in that moment his mother came back home leading the embarrassed Nagatoro to leave the home with minimal explanation.

The following morning, Senpai felt better and woke up asking why he had such a weird dream, then his mother asked him who was the "adorable girl" who took care of him the previous day and if she was his girlfriend, leading the boy to blush and reply that she was simply a kōhai of his. Later, while walking to school, Senpai realized that it wasn't a dream and Nagatoro really came to his house and took care of him while he was sick. After they meet along the way there was a moment of mutual embarassement, then he 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 name.

Webcomic
In the original webcomic, Hachioji senpai is mostly an unseen character and the stories is often narrated in a first-person perspective through his point of view. In said iteration he is even more of a doormat for the highly sadistic Hayase Nagatoro.

At the beginning of the story he and Nagatoro apparently knew each other for a while and, the day after having cheered for her at a sport competition, Hachioji 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. Once Nagatoro proposed 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. Despite the pain, even the same Hachioji seemingly gained some sexual pleasure from the treatment. 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. Over the years, the girl 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. 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 wenting to take it alongside him.

In neither of his physical appearance the character wear his trademark horn-rimmed glasses, looking less of a stereotypical nerd.

Trivia
