He basically spends his time alone, silently working out and training. He won't open up to anyone unless something major happens. His only way of relating to others is kill or be killed. A guy with an ego that's way too strong.

Gender: Male Height: 201cm Weapon: Hand-to-hand combat Personality: Violent and arrogant. Lacks empathy; a pure psychopath who will punch you with a smile on his face. The ratio of days he'll punch you to days he won't is about 7:3. Extremely moody.

Physically the strongest, personality the worst. He's not just a psycho, he's also sharp, which makes him a huge pain. Tactless. Is hated by everyone (and doesn't care). Poor at reading and writing.

Gender: Male Height: 187cm Weapon: Sniper rifle Personality: Free-spirited and cat-like. He's self-centered and has little interest in others. He's detached and lacks passion for anything, but comes alive when he's causing mischief.

He has that jaded, cynical vibe common to angsty pretty boys. He gets more foul-mouthed with people he's close to. Casually slips insults into conversation. Will sometimes give a sudden, soft laugh. Has hay fever.

Shion Gender: Male Height: 192cm Weapon: Katana Personality: The most normal one among the problem children (by our standards). He's sensible, but when he snaps, he'll go on a rampage, swinging his sword around. Is he actually the craziest one? He's caring. Thinks of the other problem children as kids.

Everyone's mom. He does all the housework and looks after everyone, but he's rarely thanked for it (sad). If someone is suddenly kind to him, he'll cry. The long-suffering one.

Gender: Male Height: 181cm Weapon: None Personality: Always cheerful and high-energy, no matter the situation. Completely unable to read the room. He's just loud, not violent.

An exhibitionist, masochistic pervert. He was sent to the Problem Child Wing due to his mental instability. Despite being weak, he pesters everyone with his loudness. He usually gets beaten up, but he's gotten so used to the pain that no one can stop him anymore.

Gender: Male Height: 205cm Weapon: Pretty much anything. Personality: A frivolous and elusive playboy. His mood swings are drastic, with good days and bad days. When he's in a bad mood, stay away, he's dangerous. He might suddenly attack you.

Akami Gender: Male Height: 194cm Weapon: Knuckle dusters Personality: Stalkerish and obsessive. Despite his large frame, he's as timid as a small animal. He relies on Shion as a fellow Japanese person. Unconsciously sadistic.

He wants to completely control anything that catches his interest. He has a strong desire for dominance, and when he gets worked up, he impulsively resorts to violence; has a tendency for domestic abuse. It's all for love. He's usually quiet, but he loses control with the person he falls for. Violence = Dominance = Love.

Gender: Male Height: 176cm Weapon: Strategic mind Personality: A cold, unfriendly little brat. Negative social skills. A closet pervert.

The youngest member, a game nerd. He fundamentally shuts himself off from interacting with others. A gamer through and through. He was sent to the Problem Child Wing because his grades dropped from playing too many games. A virgin.
