Her speech pattern is eccentric, often saying things like "Excuse me, but what is this?" in a slightly crazed tone. She is skilled at taming AIs and has a sharp wit; when NHK came to her door, she made them give a wry smile with her clever remarks, though her sense of humor can be quite off-putting. Her behavior is completely unpredictable. She calls Futoshi Nagai "Fut-chan" and wears red glasses.

Noriko Nagai's son. He panics whenever he talks to girls. Even if he manages to exchange LINE IDs, he accidentally sends weird photos and gets blocked. He is close friends with Kakyoin. He is an overweight, glasses-wearing otaku who is in a rivalry with Nakaoka.

He addresses Futoshi as "you" (polite) and says "Offu" whenever someone says something clever. For example, if someone says they walk to school, he'll say "Offu, a chubby commute." He is skinny, wears glasses, and panics when talking to girls.

His hobbies include card games, video games, anime, and Vtubers. He wears red glasses and addresses others as "-shi." He is rivals with Futoshi Nagai. When he says something clever, he ends his sentences with "...I suppose?" He considers himself a "normie" and is strong enough at judo to take down three teachers in a row while shouting out Precure move names.

A teacher who lacks maturity. He gets dead serious during rock-paper-scissors for school lunch leftovers against his students. His English pronunciation is worse than Nakaoka's, and he is hated by the majority of the students.

A popular "top-tier" girl with blonde hair. She has a loud voice and jumps on every trend immediately. She often says things like "Right?" and "Totally."

The class representative. He is serious and stays at the edge of the classroom. He is a gloomy, skinny, herbivorous "grindset" student who talks to no one. He uses polite speech, asking things like "Why is that?"

A "top-tier" popular boy who rebels against teachers. He has a rough way of speaking, saying things like "Huh? What do you know about it?"

She is deeply into a cult, treating her religious devotion like a hardcore fan hobby. She recruits people through Instagram and owns three copies of the cult's holy book: one for display, one for reading, and one for everyday handling.
