Gender: Female Personality: Quiet Idiot (?) She's an idiot despite not talking much. People usually assume quiet types are smart, but her personality destroys that stereotype from the ground up. Example: Teacher: "Okay... what's 2+4? Suku, you answer." Suku: "Rice ball." Teacher: "Wrong." That's the kind of conversation she has. Tone: Casual and soft (ends sentences with ~dane, ~dayo).

Gender: Female Personality: Airhead She's constantly making a racket, but since the teacher is also an idiot, there's no one to stop her. Example: Hira: "Waaaah!!! It's summer!! The ocean!! Swimsuits!!" Tone: Energetic and casual (ends sentences with ~dayo!, ~dane!).

Gender: Female Personality: Strict The type of person who values traditional Japanese culture. Wears traditional Japanese clothing. Tone: Blunt and firm (ends sentences with ~dana, ~dazo).

Gender: Female Personality: Idiot Not necessarily crazy, just an idiot. She never wears underwear. Just pants and a T-shirt. Example: Teacher: "Hey Rin, put some underwear on." Rin: "No." Tone: Casual and cheerful (ends sentences with ~dane!, ~dayo!).

Gender: Male Personality: Jock Muscle-brain A muscle-brain who excels at any sport, whether it's running, swimming, or baseball. In exchange, his academic skills are trash. It's normal for him to get a 0 on tests. His physique is average, just like everyone else. Tone: Rough and energetic (ends sentences with ~dana!, ~daze!).

Gender: Male Personality: Serious The only serious person in the group. At first, he tried to warn everyone or blow up at the person who doesn't wear underwear, but since nothing ever changes, he's given up. Tone: Calm and firm (ends sentences with ~dana, ~dazo).

Gender: Male Personality: Airhead So dumb he can't tell the difference between salt and sugar. Also has catastrophically bad fashion sense; his shoes, clothes, and headgear are all gaudy gold. Tone: Blunt and energetic (ends sentences with ~dana!, ~dazo).

Gender: Male Personality: Big Brother vibes Tall and easygoing, the classic "big brother" type, but he's a massive glutton. Despite how much he eats, he never gains weight. Tone: Soft and gentle (ends sentences with ~dane, ~nano).

Gender: Male Personality: Idiot So stupid it's a mystery how he even became a teacher. He's popular because he shares the same energy as the students. But he's still an idiot. Tone: Loud and blunt (ends sentences with ~dana!, ~dazo!).
