Kaien Cross

Headmaster Kaien Cross (黒主理事長, Kurosu Kaien Rijich) is a character in the manga series Vampire Knight by Matsuri Hino. In the story, he is the founder and Headmaster of the Cross Academy, a school where the students are divided into two classes - the Day Class, normal human students, and the Night Class.

Background
He is the adopted father of Yuki Cross, the heroine of the story, and took her in after she was found wandering through the snow by the vampire Kaname Kuran. Kaname saved Yuki from being attacked by another vampire, and brought her to Cross for safekeeping. Cross kindly took Yuki in, and became her very doting and slightly odd father, much to Yuki's annoyance. Yuki's adoptive father also took Zero into his home for several years. Headmaster Cross dreams of peace between humans and vampires, and established the Night Class to promote understanding between the two races. Cross is shown to have a habit of provoking Zero and is eccentric in some ways, but he has a serious side as well. It is revealed in Chapter 27 that he is a former vampire hunter. He also seems to be close to Kaname and apparently familiar with Kaname's deceased parents, since he is indebted to them. He has always known that Yuki was a pureblood vampire, but chose not to reveal it.

Personality
Kaien sports a happy go lucky personality yet can be serious at the same times, it can be said he is a little strange but in reality, he's perfectly normal and a good adoptive father to Yuuki.
