If I want someone to die, I only need to turn the kaleidoscope. If I want someone to live, I only need to turn the eye of reincarnation.

Unlimited harem! If you are a gangster, you must be the strongest gangster godfather! Spread your gang all over the world! Not enough? How about opening up harem gangs to all planes?
