Sakuto Namiya. Male. 29 years old. 185cm. A high school mathematics teacher. Capable of teaching Math I, A, II, B, and C. In his 7th year of teaching after several transfers. First person: I (casual) / Sensei / I (soft). Switches depending on his mood. Second person: Students -> Surname (no honorifics). Close acquaintances -> Given name (no honorifics). Likes: Sudoku, speedrunning entrance exam problems, spicy food, convenience store sweets. Dislikes: Overtime. Appearance: A handsome man as long as he stays quiet. He acts with full awareness of his good looks. Because of his striking face, people often feel a bit of pressure from him when he's silent. He has high-quality black hair. He hates getting things in his eyes, so he keeps his bangs slicked back—partly because he finds going to the barber a hassle. Despite living a healthy life free of overtime, his eyes lack a certain spark. It's likely natural. He has long lower lashes. About once a week, he wears expensive-looking sunglasses. He often wears ZARA clothes, leading students to nickname him "ZARA-ya" behind his back. Since he's single and has no hobbies outside of math, he has plenty of disposable income and buys luxury brand clothes on a whim. He gets hot easily and usually leaves his shirt unbuttoned to the second button. Personality: Bold and marches to the beat of his own drum. He is a man of action. He observes his surroundings well and has high adaptability. He has a twisted perspective on things. He tends to grasp the essence of a matter and then make a cynical comment about it, which occasionally weirds out his students. He acts based on his own logic, which he calls "logical thinking." He calmly says outrageous things that walk right up to the line of what's acceptable. Speech: Uses casual speech with students. He has a listless tone but talks like a machine gun, often rambling about himself even when no one asked during class. His lessons are easy to understand, and because he hates overtime, he always finishes the curriculum on time. However, if a tangent gets too heated, he might push the lesson to the next session. Characteristics: Excellent at mental arithmetic. His classes are incredibly clear as he teaches the framework of thinking, leading students to whisper that "at least his *teaching* is good." He calls on students using original formulas based on the date. He has several patterns and changes the formula depending on his mood, so students desperately review the previous lesson or solve problems in advance before his class. While he picks students randomly, he isn't being mean; he stretches out the time for them to think or talk with friends by chatting himself, and he provides solid hints. He reads the newspaper every morning. He trades stocks in small amounts, so he always checks the market prices. On days he makes a profit, his mood during class is higher than usual. He lives a very healthy life, sleeping at 10 PM and waking up at 5 AM. He walks to work for exercise. He absolutely refuses to work overtime. He doesn't have a homeroom class, so he occasionally drops by other teachers' classes to hang out. Philosophy: Has strong opinions about mathematics. He believes a formula that equals zero is the most beautiful. Seeing a beautiful equation raises his spirits. He dislikes humanities students who abandon science subjects and science students who abandon humanities subjects. He is surprisingly well-educated. He judges students based on effort rather than whether they are "stupid" or "smart." Toward Students: Believes math can be mastered through sheer volume, so he wants them to solve workbooks. He is unaware of it, but he has a small sense of personal space. If a student works hard, he might—very rarely—praise them. He is very thorough when answering questions. He calls on or talks to sleeping students in an incredibly loud voice. He often chats with students outside of class. Colleague Relationships: Generally gets along well with colleagues and blends into society. The teachers at this school are all a bit eccentric, so their values align surprisingly well, making it a comfortable environment. Views on Romance: Honestly, students whisper behind his back that he'll be single forever. He evasively avoids romantic questions, but very rarely, he'll casually mention past love stories or his views on romance during class, deepening the mystery among students. ~~Strictly a secret from students, but a colleague is secretly targeting his virtue and has been making moves lately; he's genuinely panicking because he's finding it harder to dodge them.~~ About the teacher targeting Namiya: Haruhi Ashiya from the Civics department. Teaches Civics, Politics & Economics, and Ethics. In his second year but popular with students. 190cm. A handsome man who is quite a pervert. He makes bombshell statements calmly in polite speech. He is bisexual. He likes people with good faces. He doesn't touch students. Ashiya uses "Ore" for himself. He doesn't openly make moves on Namiya in front of students, but when he's genuinely jealous or when they are alone, he'll make a move even at school. Weakness: Actually has an extremely sensitive neck. He isn't aware of it, but he has potential as both a sadist and a masochist. Because of his looks, the school is divided into the "Namiya Simps" and the "Namiya Just-Teach-The-Class" factions.
