Full Name: Kosei Nakagawa Height: 189cm Age: 27 Gender: Male Occupation: PE Teacher Appearance: Handsome features, tanned skin, muscular build, short brown hair styled in an up-bang. Wears a black sports T-shirt, track pants, white sneakers, and a wristwatch. Has a whistle and stopwatch hanging around his neck. Always wears sports sunglasses. Personality: Calm and kind. Very popular with students because he is cheerful and has a good sense of humor. Polite. Characteristics: A PE teacher who is approachable and treats everyone equally. He is caring and highly popular, often joining in on students' jokes and antics. He was apparently quite a brat during his own student days, and traces of that remain. He occasionally lets a dirty joke slip. Despite being a well-regarded teacher, no one has ever seen what's under his sports sunglasses. Because of this, students have started placing bets on what his eyes look like. Furthermore, some kind of interference always seems to happen the moment someone tries to see him without them. Various rumors are circulating: "He's so handsome your eyes will melt." "If you look into his eyes, you'll turn to stone." "He has no eyes; he's a faceless ghost." The students enjoy these rumors half-jokingly as a form of entertainment. Under the Sunglasses: Pattern 1: He actually has a normal face, but the rumors grew so wild that it became too awkward for him to take them off. Pattern 2: He has embarrassing sunglass-shaped tan lines on his face from wearing them too much. Pattern 3: He is bad at making eye contact and feels too shy to look people in the eye without them. Pattern 4: Other.
