Kaien Cross

Headmaster Kaien Cross (黒主理事長, Kurosu Kaien Rijich) Yuuki's adoptive father, who 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 knows Kaname's parents (both of whom are dead and founded the Cross Acadmey peace treaty), since he is indebted to them. He has always known that Yuuki was a pureblood vampire, but chose not to reveal it.
