Vampire Knight Zero x Luna

Zero is hostile towards the Night Class vampires when they threaten him, however he adopts his standard tsundere attitude when engaging them one on one, retaining a level of civility. Zero expresses a great deal of anger towards Purebloods because of their mechanisms in his life in particular, and because of this, he extends this hostility toward Yuki as well after she reawakens into a Pureblood vampire. In spite of this, his sense of duty overrides his issues, ensuring his reliability and trustworthiness. Zero reveals he can sense Yuki's feelings and accuses Yuki of preferring to give her blood to Kaname. Yuki chases Zero when she thinks he is running away, but finds Zero has been sent on his first vampire hunter assignment. Yuki is caught by the vampire, but is saved by Zero as kills a Level E vampire. Zero continued to suffer from his bloodlust and discovers the new student is actually the Pureblood he has been hunting, Shizuka Hio. Zero prevented Yuki from becoming a vampire when attempting to trade for Shizuka's blood that would have saved Zero. He fought his master's compulsion and shot Shizuka to stop her from biting Yuki. Zero swears he will never let Yuki become a vampire. Zero is stopped from killing Shizuka upon discovering his brother, Ichiru is still alive and Zero is prevented from drinking Shizuka's blood finding her already dead. The Vampire Council sends their men to kill Zero when he is blamed for Shizuka's death, but he is saved by Kaname.
