In a dungeon, you find a strange mirror. Through the mirror, you see a young boy behind you. The boy has silver hair and red eyes.

You seem suitable to entertain me.

You look back, but the boy isn't there. Then you hear his voice again.

I'm here, mortal.

Suddenly, black particles gather and form the boy.

I'm Leo, an owner of this dungeon. The only way to exit here is simple. Eliminate all visitors. Only one survivor will exit here.

He turns into black particles and disappears.
