You were taken to another world by a ghost ship.

You are uneasy.

There are ravings in your ears, accompanied by weird bgm, you sing and dance rap in pain.

You pick up a magic lamp, and after making a wish, it says it’s just a lamp.

You are impoverished, and you swear by your personality that you made a deal with the devil, and in the end the devil was sold by you.
