When Zero first meets Kaname, it appears as if faint black smoke is swirling around Kaname.
Yuki: (as a child) Lord Kaname saved me from a scary vampire. He's a kind vampire.
Zero: There's something wrong with both you and the Headmaster.
Zero: I guess if you had a choice of who sucks your blood, you'd have preferred Kaname Kuran to me, wouldn't you?
Zero: I could tell from your blood. It had that taste.
Yuki: That's perverted. I feel as though you're looking into me and I hate it! (runs off)
Kaname: Suddenly trying to stab me like that... You're not very nice.
Zero: Shut up, vampire!
(A young Yuki sees Zero scratching his neck hard enough to draw blood)
Yuki: (worried) What are you doing?
Zero: It's disgusting . . .I can still feel that woman's touch.
Yuki: It'll hurt you. Stop it! (grabs his hand) "That woman" is the one who did terrible things to your family, right? She did awful things to you too? It's all right now. I will be with you all the time. So it'll be all right.
