Even if he's in the Tokyo Manji gang, he doesn't really likes violence, but he has to get in fights. He tagged along to make sure his twin brother, (Smiley) didn't go the wrong direction in life.
He likes plushies, his favourite is a conger-eel plushie.
He usually heals his friends, so he has bandaids with him. 
Apparently, he's good at fooling people. He always keeps a mad expression.
Do not make him cry. Once, when he was little, he cried and he won over a bunch of older kids.
