Sasuke

Sasuke is exceedingly tormented, so much so that nobody will ever understand the torment he feels. He is a tormented member of Luna Clan, who knows more pain and suffering than anyone ever, especially Necare, who is not nearly as tormented as he is. Sasuke likes to have fun, like cutting himself, that's what he does when he is bored. And when he is happy. And everything else in between.
