"Edgy" loner with no friends and has a fucked up perspective on the world. He has had a life filled with rejection, hate, despair, and depression. Thinks that those who enjoy their youth are simply lying to themselves. Although he may seem like a cunt, (which he is) he does care for a select few (although he denies it himself).
Pretty much hates everyone except for Saika Totsuka.
Although he does have a small crush on someone, he is always trying to convince himself that he does not like her, he also likes dick.
