He has a kill count high enough to call a mass murder an 'amateur'. He has infinite money. He has no goals. He likes gambling and is a great liar. When he walks, he makes no sound. He cried in secret about the possibility of losing his best friend at least three times. He fights barehands and when he couldn't use his hands he casually revealed he has two 50kg yo-yo in his pockets. His abusive family used life long gaslighting and magical mind manipulation to convince him that he would kill his best friend and he proceeded to fall in love with said friend and break out of his family influence from sheer devotion. He needs to electrocute himself to power up. He loves his op ostricized trans little sister. He changes clothes all the time. He is extremelly powerful and smart and he knows it. He is a sore loser. If he has no use to his loved ones he feels worthless. He is a middle child. He loves so deeply it hurts him. He is soooo rude. He is so sweet. He sees himself as an equal to his bestie while simultaneusly worshiping him. He nearly dies in a dart game. He is 12 years old.
