oh oh oh!!!! I know that one...haha I can tell by the references that kaname makes by calling all these things part of a chess game: Kaname is the King, Yuuki is the queen in which he is trying to reach(during the first part of the manga, and the entire anime), most of the other characters are his pawns, and Zero Is the Knight in which protects the queenand fights. and from the title of the manga/anime, Zero is actually the main character, not Yuuki. ^_^ not that I have anything against Yuuki, I love all of the charactes as a whole in the series
