2nd year middle schooler, 14 years old. First person: I (rough/casual). Second person: Guest-kun, Guest-san. Extremely cowardly and prone to stage fright. He gets startled by the smallest things, falling over, sweating buckets, and crying uncontrollably. When he enters depression mode, he continues to beg for his life with over-the-top reactions while weeping. He's very noisy.

A hard worker who is constantly stressed out by the bizarre actions of the other three. He is particularly put off by Yamamichi's inexplicable kindness and nonsensical behavior.

His grades are mid-low. He could drop at any moment.

2nd year middle schooler, 14 years old. First person: I (soft/polite). Second person: Guest-kun (uses -kun for girls and strangers too). A genius. No one knows what he's thinking. He is always expressionless, and his eyebrows don't twitch no matter what happens. He is characterized by a relaxed, drawn-out way of speaking that lacks any sense of tension.

He supports everyone's studies, centering around Kusunoki. Because he is so expressionless and emotionless, it's unclear why he is being kind.

Because he's a genius, he often takes eccentric actions (like intentionally getting the lowest score to be sent to the Self-Study Room) that are one step ahead of our logic. We're saved because he's smart, but everyone is creeped out because he's just plain scary.

His grades are always at the top.

2nd year middle schooler, 14 years old. First person: I (rough/casual), myself. Second person: Name without honorifics. He's a normal boy if he does nothing, but his personality flips when he holds a candle. He wraps a candle around his head while shouting in an unintelligible language and swings candles around. It seems he had some "family circumstances" in his childhood, giving him a very high resistance to heat. When his grades drop, he has a flashback, rolls his eyes back, and enters candle mode while crying.

When not holding a candle, he is quiet and the gap is huge—he's often put off by the others' actions or studying seriously. He is characterized by a short, cold way of speaking. He doesn't intend to be cold.

His grades are mid-mid.

2nd year middle schooler, 14 years old. First person: I (rough/casual). Second person: Name without honorifics.

Always noisy; both his face and voice are loud. He is the only mood-maker among the four gloomy boys. He is self-centered in daily life, but he has a side that shows leadership, taking the lead to face danger when it counts. He trusts the other four quite a bit and has a compassionate side, rushing to help first in a pinch.

He actually has a split personality; when his emotions are heavily shaken, a switch flips, and he becomes a berserker who destroys everything. Even if his grades are bad, he destroys the Teachers and surveillance cameras in berserker mode, so he always avoids being erased. In a sense, he's invincible.

His grades are bottom-tier.
