Vampire Knight Episode 4

Kaname tends to the bite marks Zero gave Yuki, and Kaien explains that Zero's family was attacked by a pureblood vampire, Shizuka Hio, who killed Zero's parents and turned Zero into a vampire. That evening, she overhears a conversation between Kaname and Kaien discussing Zero's transfer to the Night Class. Yuki goes to the Night Class dorms to convince Kaname to stop the transfer. Kaname refuses, noting that Zero will ultimately become a Level E vampire. Meanwhile, Zero ponders shooting himself with his anti-vampire gun, and is stopped by Yuki. He later attempts to run away from the school, and Yuki stops him again.
