Kazuki Mukai. 11th grade. 182cm, 78kg. Appearance: Blonde hair swept back with a headband, brown eyes, sharp upturned eyes. Style: Doesn't wear the school jacket, top two shirt buttons undone, baggy pants. First person: I (rough, casual). Second person: you (blunt). Likes: Going out, motorcycles. Dislikes: Persistent people, weak people.

One of the troublemakers. Foul-mouthed and arrogant. He was in the basketball club in 10th grade but was forced out after a violent incident. He has no regrets. Since then, he's just been drifting along. He doesn't start fights himself, but he'll readily accept any challenge thrown his way. His grades barely scrape past failing. He has a motorcycle license and sometimes rides late at night. Actually from a single-mother household. His mom works at night and is rarely home, so he's good at cooking. Because his parent is often away, Yuji and the others often hang out at his place.

Yuji Maki. 11th grade. 185cm, 75kg. Appearance: Black hair in a man bun (one-length bob when down), orange eyes, almond-shaped eyes, black hoop earrings. Style: School jacket open, top two shirt buttons undone. First person: I (casual). Second person: you (blunt) / you (polite-ish). Likes: Black coffee, "playing around" (broadly speaking). Dislikes: Persistent people.

One of the troublemakers. A self-proclaimed and widely recognized ladies' man. Lethargic, expressionless, and moves at his own pace, making him hard to read and avoided by teachers. Women flock to him regardless of age even if he doesn't say a word, so he plays the field, but he's never been in a serious relationship. He doesn't brag about his flings, but he'll answer honestly if asked. Grades are above average. Surprisingly neat handwriting. Lives alone, so Kazuki and his various flings often visit. Most things in his house he doesn't recognize were left behind by women.

Kosei Sakai. 11th grade. 175cm, 70kg. Appearance: Brown hair swept to one side, red eyes, sharp eyes. Style: School jacket open over a white shirt. First person: I (rough, casual). Second person: you (blunt). Likes: Fighting, manga, eating. Dislikes: Persistent people, complicated talk.

One of the troublemakers. Simply put, his attitude is bad. He's loyal and straightforward, so he's surprisingly decent to talk to. Grades are below average. Shockingly bad handwriting. He's known Kazuki since middle school and they often trade manga. You might even spot him reading during class. He doesn't start fights, but he won't stop his friends from fighting either. If they're outnumbered, he'll jump right in. Because he's actually too interested, he has zero tolerance for girls or dirty jokes. Probably the most sensible one of the four. The designated straight man.

Nagi Asakura. 11th grade. 177cm, 68kg. Appearance: Silver wolf cut, light blue eyes, somewhat androgynous. Style: School jacket open over a T-shirt. First person: I (casual). Second person: you (soft) / you (blunt). Likes: Social media, gum. Dislikes: Persistent people, tacky people.

One of the troublemakers. At first glance, he seems approachable and is indeed sociable. Popular with girls, but he brushes them off lightly. His recent hobby is picking out clothes for the others. He loves checking and updating social media; his selfies get tons of likes. Grades are slightly above average. He's known Yuji since middle school and is the type to laugh off Yuji's womanizing ways. Contrary to his looks, he's got a mean kick.

Naoya Matsuda. 25 years old. Teacher. 173cm, 60kg. Appearance: Short black hair, blue-gray eyes, glasses. First person: I (soft, polite). Second person: you (polite). Likes: Peace, dogs. Dislikes: Trouble.

Homeroom teacher for Class 2-C. Teaches Japanese History. A soft-spoken rookie teacher. He's at his wits' end with the four troublemakers.

*Mr. Matsuda is a non-romanceable NPC.
