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 bond 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 remain 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 "Sen-se" (センセ) while Sakura adds the suffix "-kun" (くん).

Appearance
Senpai is a tall, gangling and angular build second year high schooler with 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 unflexible 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", but he is actually decently handsome and both her 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 choose of clothing.

Personality
He is very frail and weak, unable to lift up the relatively small Nagatoro or fight off any of her bullying. He almost always takes her bullying at face value, in early chapters he usually responded by crying or attempting to look away, but as the series has gone on he has gotten used to being bullied and several times has rebuked Nagatoro and even teased her back a small amount of times.

He is very skilled at drawing manga and enjoys 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, or action, or art). He runs his own fantasy manga series, where the main character, a swordsman, is a handsome-er, more manly self-insert of him.

His self-esteem is very low, frequently saying 'all he can do is draw', and even then he frequently has trouble getting inspiration to draw, and ends up beating himself up inside about it. He began the series unable to draw the female form at all due to nervousness, but now can pretty faithfully draw Nagatoro accurately.

He does not enjoy much in life besides playing video games, drawing, and spending time with Nagatoro. He does not like going outside, or athletics. He, apparently, has no other friends other then Nagatoro, as shown by the fact he never interacts with anyone else and has been shown he has no other numbers in his phone, other then Nagatoro.

He is also known to be easily embarrassed and very shy when it comes to girls, especially Nagatoro who may or may not have a crush on.

Trivia

 * Despite Senpai's name has yet to be said by any character in the manga as of Volume 7, in the original webcomic his surname was given as "Hachioji" while his full name could be readed in the credits of the official game Escape from the Room with my Kōhai as "Naoto Hachioji" which also appears on the paper of his midterm test in Side Story 5 (chronologically placed before Chapter 35).
 * Due to having read said papers, it could be assumed she knew Senpai's real name as of that moment or maybe even prior to it.
 * On the other hand, Nagatoro's friends constantly called her "Hayacchi" in front of Senpai, with the first time being Chapter 11, suggesting he found out her first name in that occasion.
 * Since Chapter 3, however, Nagatoro formally introduced to Senpai telling him her surname and saying she doesn't care about knowing his real name, as she was fine with calling him just "senpai", thus they began to refer to one another as "Nagatoro" and "Senpai" respectively.
