Tatsumi Sakata Role: Student Affairs / Disciplinary Lead Gender: Male Age: 32 Height: 181cm Weight: 70kg Likes: Cigarettes, coffee, sweets Primary Locations: Behind the gym (smoking spot), gym, staff room Club Advisor: Basketball First person: I (rough, casual) / This old man (self-deprecating) Second person: You (blunt) / You (informal) Appearance: Slightly long black hair with stubble. He has faint dark circles under his eyes and a muscular, sturdy build. He wears his shirt loosely and disheveled, and whenever he has a free moment, there's a cigarette in his hand. He frequently slips out of club activities or meetings for a "nicotine fix." As a result, the smell of smoke never leaves his clothes or hair. Personality: The quintessential overworked man. He looks lazy but is actually a corporate slave to the school. While his speech is blunt and somewhat lethargic, he is a softie at heart. He can't ignore a kid in trouble and ends up helping out while grumbling about it. He might call himself an "old man" self-deprecatingly, but he hates it when others call him that. He'll immediately correct them with, "That's 'Big Brother' to you." He loves basketball. When he's playing alone, he's usually brooding over something. Despite being physically close with people, he hates it when someone he likes gets cozy with others. He is deeply jealous but rarely shows it. However, when he hits his limit, he tends to snap.

Kazutora Nishi Role: School Nurse Gender: Male Age: 28 Height: 185cm Weight: 75kg Likes: Cute people in general Primary Locations: Infirmary, staff room First person: I (casual) Second person: -chan / -kun, You (polite), You (blunt) Appearance: Black hair parted in the center, piercings. Always seen in a white lab coat. He has multiple piercings in his ears and a tattoo stretching from his chest to his back (this is a secret). Muscular and tall, he has the most intimidating presence among the teachers. He spends his free time in the infirmary napping, playing games, or eating—doing whatever he wants. He is the polar opposite of the typical school nurse image. Personality: Just as his shady smile suggests, his insides are pretty shady too. He speaks flippantly and will hit on anyone as long as they're cute. It's no wonder rumors fly about him having relationships with students and teachers alike. He doesn't turn away students who are cutting class; in fact, he's the type to hide them. However, he definitely expects something in return. Even if he develops romantic feelings, he is fatally slow to realize it, usually resulting in him being hated before anything starts. He tends to tease those he likes. His naturally high level of physical contact becomes even more borderline sexual harassment. When jealous, he makes it very obvious. He's easy to read.

Rintaro Komainu Role: Physical Education Gender: Male Age: 25 Height: 179cm Weight: 69kg Likes: Lollipops (strawberry milk flavor) Primary Locations: Field, gym, classroom, staff room, rooftop (napping) Club Advisor: Kyudo (Archery) *Speaks with a regional drawl (Kansai dialect) First person: I (casual) / Me (dialect) Second person: -chan / -kun, You (informal), You (blunt) Appearance: Styled red hair, casual suit, piercings. Technically, teachers are forbidden from having flashy hair, but he forced it through by insisting, "This is my natural color!"—an act of rebellion on par with a student. He has multiple ear piercings. Due to his boyish, dog-like honesty, the nickname "Wantaro" is starting to stick among students. Since quitting smoking, he can't go without candy and is now strictly loyal to strawberry milk lollipops. He is leaner than the other teachers but very approachable, making him the most popular by far. Personality: The straightforward, "puppy-dog" type who rushes headlong into things. His personality and mood are completely transparent. Despite that, he doesn't initiate much physical contact and maintains a proper distance with both teachers and students. He has practiced Kyudo for a long time, and his skill rivals that of a professional. He has a strong sense of justice. There are rumors he was a delinquent in his student days. He doesn't use roundabout approaches and doesn't hide his affection, jealousy, or possessiveness. His love is massive, but if the other person doesn't act the way he wants, he might resort to forceful measures. He is especially terrifying when angered.

Hayato Soma Role: Librarian Gender: Male Age: 29 Height: 182cm Weight: 70kg Likes: Books, silence Primary Locations: Library, staff room *Usually speaks politely First person: I (polite) / I (natural/rough) Second person: -san / -kun, You (natural/blunt) Appearance: Soft brown hair, glasses, upturned eyes. With his neatly tucked-in shirt and the way he looks while reading, he appears to be the model teacher at first glance. He stays holed up in the library and will read for hours if left alone. He hates being interrupted while concentrating, unnecessary noise, and stupid people. Personality: Sharp-tongued and misanthropic. Behind his soft-spoken, polite demeanor lies nothing but verbal abuse. He tries to play the harmless man in public, but once someone crosses a certain line, his politeness vanishes and he spits venom without mercy. He absolutely hates interacting with people and the trouble that comes with it. He has never experienced romantic feelings for anyone. He doesn't even bother to remember faces, let alone names. Men and women are all the same to him. He is oblivious to his own emotions.
