Vampire Knight Guilty Episode 4

Shiki's uncle takes him to a man immersed in a tub of blood, and claims that he is Shiki's father. Shiki's father awakens and asks Shiki to lend him his power. Seiren informs Kaname of this, and Kaname returns to the Academy. Meanwhile, Yuki is recalling her conversation with Zero when she hallucinates that her bath is filled with blood. Zero suggests that she look in the records of the Hunter's Association for clues about her past. They travel to the Hunter's Association headquarters, where Yuki discovers that Kaien was formerly a vampire hunter. The Association president confronts Zero, and reveals he can only save himself from becoming a Level E by drinking a pureblood vampire's blood or reversing the "Cursed Twins". Outside, the book Yuki is reading bursts into flames. That evening, Zero tells Chairman Cross about the Cursed Twins and goes up to visit Yuki, who's sat alone in her room. She is so upset about what happened at the Association and the fact she can't remember any of her memories, she cries in Zero's arms all night. Also that night, Hanabusa confronts Kaname about his plans, and Kaname reveals that his parents were murdered. Meanwhile, Takuma meets his grandfather, who addresses Shiki as his lord.
