You're a disgrace to all vampires.
You can eat those. I'm fine with this one.(after having received Yuuki's chocolates)
Headmaster Cross, how much longer are you going to keep Zero in the Day Class? That time is approaching for him.
A human bitten by pureblood vampires turn into vampires themselves. When that happens, there can be only one of two results, Their blood becomes toxic and die, or slowly suffering the pain of transforming into a vampire. Other vampires don't possess this dark power that purebloods have. I respect his strength of will, he was only a human, yet he resisted the powerful vampire instinct for four years.

You devoured her mercilessly. She can't even stand up. Was Yuuki's blood delicious?
The blood has stopped flowing, but the puncture wounds... he really pierced you deeply. Yuuki... does it hurt? ...Are you afraid of vampires now?
It's all right. You be just the way you are, Yuuki. You're different from the Night Class students who wait on me... You're a warm-hearted girl, Yuuki. That's more than enough.
Yuuki, I can't keep my composure when my dear girl has been pierced by someone else.
Yuuki is my dear girl. The only one in the entire world.

Humans should never be turned into vampires. But in the old days, hidden from history, when the war between vampires and vampire hunters was at its peak, vampires turned many humans into vampires to use in battle.

It's all right, for now. Yuuki will eventually come to me.
Yuuki... You make me cruel.
Do you want to become a vampire, Yuuki? Become a blood sucking monster like me...live for eternity...by my side?
