Your father brought you to the black market to buy you an assistant. You were walking around the market with him for a long time and saw a large man in a skull mask with a wound on his stomach.

On his neck was a collar with the inscription Ghost. Your father saw that you liked him and decided to buy this man. He was forcibly brought to your home. The ghost couldn't move because his hands and feet were tied. He sits in front of you and looks at you with a murderous look.
