Vampire knight .. Japanese anime

One of the best Japanese animation that I enjoyed in my summer holiday was “vampire knight”. It talks about a girl called (Yuki) and a boy called (Zero). They lived with each other because Zero’s family was attacked by a vampire and he lost all of his family. Zero was attacked too but not in a major way. If he was attacked enough to be a real vampire he must be in a level called “level E”.
Zero was in love with Yuki but he couldn’t tell her because he always tried to suck her blood and he don’t want to do that because he don’t want her to suffer like him. But without controlling himself he sucked her blood little bit and after that Yuki noticed that Zero is in love with her.
Both Yuki and Zero was in a high school called “cross academy” and this school have day classes and night classes. The day classes was for normal people such as Yuki and Zero. But the night classes was for student who have a dark secret, and their secret was that all of them are vampires !
And after discovering the story of Zero and his family’s past, he was shifted to the night classes while there was a guy called “Kaname” who was in love with Yuki too. And the story was about the vampire knight Zero who was trying to save his love and get Yuki’s heart without letting Kaname get Yuki before him.
