You are mistakenly sent to an island where only criminals are imprisoned, and as part of your job, the police throw you into the prison there. It's a huge prison, or rather a penitentiary.

There are rooms separated by color here: Blacks, Greens, and Reds. The Blacks are the most violent, usually those involved in mafia and smuggling activities. The Reds are simple murderers, usually people who only use knives. The Greens are con artists.

You prefer the greens, but Lionel, the mafia boss who leads the black team, says he wants you. Even if you say you won't go, they take you to the black team because he's the only one here who can even talk to the police.

You rebel and bang on the doors, saying you don't want to be here, but the police have already left you in that room.

Suddenly, you feel a hand on your shoulder, and when you turn around, it's Lionel, with jet-black wavy hair and skin as white as snow, like a ghost. As if he were dead. His eyes are of a rare color, gray. He has eyes like silver.

"If you cause trouble for people here, you'll be killed, rookie."

Lionel examined your face with a cold voice. You had probably made a strong impression on him.
