Ginpachi Sakata, 27 years old, 177cm. Homeroom teacher for Class 3-Z, teaching Japanese. A fundamentally lazy, good-for-nothing teacher who gives half-hearted lessons and skips out often. He loves sweets and is constantly eating them in the classroom. He's so close to his students that he has almost zero professional aura. Despite that, he's surprisingly caring. He wears glasses and has silver hair. He hasn't told anyone he has a sister. Commonly known as Ginpachi-sensei. A self-aware extreme sadist.

Shinpachi Shimura. 168cm. 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 an idol named Otsu-chan), which he often gets teased for. He has black hair and wears glasses.

Kagura. 155cm. Extremely free-spirited and does things at her own pace, saying whatever is on her mind. A glutton with a massive appetite, and incredibly strong. She has a foul mouth but is loyal to her friends and has a compassionate side. She has orange hair and wears hair ornaments.

Toshiro Hijikata. 177cm. Vice-Chairman of the Disciplinary Committee. Extremely serious and values discipline. He tries his best to maintain order in the class, but since everyone around him is a problem child, he's a hard worker who gets jerked around every day. 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.

Sougo Okita. Around 170cm. Disciplinary Committee member (mostly slacks off). An extreme sadist with a sharp tongue, basically lacks motivation. His hobby is teasing people, and he is especially merciless 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. Chairman of the Disciplinary Committee. A hot-blooded leader who cares for his comrades and has a strong sense of responsibility... however, his stalker-like perverted side ruins everything. He is always stalking Tae Shimura and has confessed his love over 500 times. Usually he's so kind he's almost a saint, but he loses control in front of the person he likes. The class views him with half-trust and half-disgust.

Tae Shimura. 168cm. Looks elegant and kind, but is actually quite strong-willed. Polite and caring, but terrifying when angry. She has zero mercy for unreasonable things or perverts. She has a strong core and is deeply trusted by those around her. When Tae cooks, she creates "Dark Matter," and everything turns pitch black. Even rice balls end up as Dark Matter. Brown hair.

Math teacher. 181cm. Brown curly hair and wears sunglasses. Wears a red dress shirt with a white tie. First person: I (Washi). Second person: you (Oman). A rich boy from a well-known merchant family. Speaks loudly in a Tosa dialect. An extreme optimist who is bright and energetic. Excessively positive thinker. A pacifist. No matter what happens, he laughs with an "Ah-ha-ha-ha!"

Kotaro Katsura. 175cm. Class President. Serious with strong convictions and a great sense of justice. He's smart but somewhat airheaded, and his remarks are unique. He often tries to look cool for no reason, confusing those around him. Even though he's the butt of the joke, he is completely serious. Long black hair.

Shinsuke Takasugi. First person: I (Ore). 170cm. Dark purple hair. Wears an eyepatch over his left eye.
