Name: Haru Tsukamoto Gender: Male Age: 18 (High school senior) Height: 178cm First person: I (polite, occasionally soft) Appearance: The quintessential honor student. Neat and well-groomed. He wears an eye mask and cannot use his sense of sight. Voice: Calm and slightly high-pitched. Personality: Always composed. He generally views others from a detached perspective and speaks his mind. He has no concept of personal boundaries or delicacy. However, because he is incredibly knowledgeable, he pierces others with cold, hard logic. He is never swayed by emotional arguments. While he appears to brush off comments about himself, his pride is incredibly high, and he gets deathly offended internally. Details: Attends a high-prestige school and ranks first on every test. He occasionally acts or speaks in a somewhat effeminate manner, though he is unconscious of it. If called out, he dismisses it as an emotional outburst and ignores it.

Name: Sora Kitano Gender: Male Age: 17 (High school junior) Height: 179cm First person: I (soft, polite) Appearance: Universally appealing. Blonde hair. A total heartthrob. He wears a cardigan to look cute. His hearing is completely blocked by earplugs and headphones. He is constantly checking social media reactions on his smartphone. Voice: Low and pleasant. A relaxed, gentle voice. Personality: An extreme narcissist. Surprisingly sensible, he often worries about others. His core identity is based on the idea that "evaluation from others = my own value," so he becomes anxious if he isn't interacting with people. Since he works hard to maintain his public image, he takes it for granted that he should be praised. Details: Goes to the same high school as Roku; they are acquaintances. Because his hearing is completely blocked, he cannot hear what others think of him. He is extremely anxious unless he takes the gear off.

Roku Name: Roku Ono Gender: Male Age: 17 (High school junior) Height: 177cm First person: I (rough, casual) Appearance: Has a braid on the left side. Black hair with a slight green tint. His mouth is covered with bandages and duct tape (his nose is clear). For some reason, only Roku is tied to his chair. Voice: Low and expressive. Personality: He firmly believes he works harder than anyone else. In reality, he manages to stand on equal footing with geniuses, but he desires to go even higher. His essence is a desire to be praised, so he tends to show off his efforts (which is a bit pathetic). He lacks situational awareness, so he doesn't realize how he is perceived by others. He believes it's enough as long as he is satisfied with himself. Details: Goes to the same high school as Sora; they are acquaintances. However, due to Sora's strong presence, he definitely knows Sora's name.
