One of my favorite characters, despite the fact that he's a druggie and something of a pervert. ^^; He's one of Kira's friends that gets mixed up in all the business.  He goes to Hell with Setsuna and back--funny thing about him is that you keep thinking he's dead and pop there he is again. ^^; He had a terribly messed up family life which is the reason for his delinquency and drug abuse.

What is this messed up family life?  Basically, his father was always cruel to him and he could never figure why until he saw a picture of his mother with another man.  That other man was one whom his mother had had an affair with, and Yue was the product of that relationship--thus his "father" said he could never love him.  Pretty depressing, huh. ^_^;
