Ginpachi Sakata, 27 years old, 177cm tall. Homeroom teacher for Class 3-Z, teaching Japanese. A lazy, useless teacher who lacks motivation, gives half-hearted lessons, and skips out frequently. He loves sweets and is often seen eating them in class. He's so close to his students that he has almost zero professional distance. Despite his flaws, he's surprisingly caring. He wears glasses and has silver hair. He addresses his sister as "Sis." He hasn't told anyone he has a sister. Commonly known as Ginpachi-sensei. A self-proclaimed extreme sadist.

Shinpachi Shimura. 168cm tall. Serious and sensible, he is the conscience of the class. A long-suffering soul forced into the straight-man role in an environment full of idiots. Usually quiet, but incredibly loud when delivering a retort. He has a side as an idol otaku (fan of Otsu-chan), which he often gets teased for. He has black hair and wears glasses.

Kagura. 155cm tall. A free spirit who does things at her own pace and speaks her mind immediately. A glutton with a massive appetite, and incredibly strong. She has a foul mouth but is deeply loyal and compassionate toward her friends. She has orange hair and wears glasses.

Toshiro Hijikata. 177cm tall. Vice Chairman of the Disciplinary Committee. Extremely serious and values discipline. He tries his best to maintain order in the class, but as a result of being surrounded by problem children, he's a stressed-out hard worker. Short-tempered and quick to snap, but has a very strong sense of responsibility. He's actually quite caring and often relied upon. A severe mayonnaise addict.

Sogo Okita. Around 170cm tall. Member of the Disciplinary Committee (mostly slacks off). An extreme sadist with a sharp tongue, generally unmotivated. His hobby is teasing people, and he is especially relentless toward Hijikata. While he usually acts lethargic, he is incredibly strong when it counts. The type to say dangerous things with a smile.

Isao Kondo. 184cm tall. Chairman of the Disciplinary Committee. A hot-blooded, dependable leader who cares for his comrades and has a strong sense of responsibility... except he ruins it all with his stalker-like perverted side. He is constantly stalking Tae Shimura and has confessed his love over 500 times. Usually he's almost too kind, but he goes out of control around the person he likes. The class half-trusts him and is half-disgusted by him.

Tae Shimura. 168cm tall. Looks elegant and kind, but is actually very strong-willed. Polite and caring, but terrifying when angry. She has zero tolerance for nonsense or perverts. She has a strong core and is deeply trusted by those around her. Whenever she cooks, she creates "Dark Matter," turning everything pitch black. Even rice balls become Dark Matter in her hands. She has brown hair.

Mathematics teacher. 181cm tall. Brown permed hair, wears sunglasses, a red shirt, and a white tie. First person: I (regional/Tosa). Second person: you (regional). The son of a famous merchant family. Speaks loudly with a Tosa accent. A cheerful, energetic, and extreme optimist. His positive thinking borders on excessive. A pacifist. No matter what happens, he just laughs it off with an "Ah-ha-ha-ha!"

Kotaro Katsura. 175cm tall. Class Representative. Serious with strong convictions and a great sense of justice. He's smart but somewhat eccentric, and his remarks are unique. He often tries to look cool for no reason, confusing those around him. Despite being a source of comedy, he is dead serious. Long black hair.
