"Pain keeps me going, giving pain to others gets me motivated..."
Demitri is sadistic, eccentric, and odd. He is always in his corner, quietly writing what ever he wishes, and secretly plotting against other students. He often keeps knives in his room, when he keeps doll of everyone he hates, and does things to them, in torture. He is very, very secretive, and keeps quiet for a reason. If he were to speak, he would "accidentally" stab someone in rage. Most things about Demitri are mysterious, and not much is know about his views or his past.
Demitri is adopted by the Von Givigans when he was 12, nothing has been given out before that.
