Hanabusa Aido

Nicknamed "Idol" by the Day Class girls. Along with his cousin Akatsuki Kain, Hanabusa Aidou is known among the Night Class as "Kaname-sama's right hand" and has a fierce admiration for Kaname. Aidou is a noble-class vampire and possesses the ability to control ice.

Background
Though he appears cheerful and friendly one moment, he can quickly become vindictive and cruel the next. Though loyal to Kaname, he has a tendency to overstep his boundaries, which results in Kaname punishing him if discovered. He has also been aware that Zero is a vampire, though he did not reveal it to anyone else because he felt it would not benefit himself in anyway and because he takes no pleasure in revealing secrets. At one point, while Yuki dealt with two day class girls (one of whom was bleeding) who violated the nighttime curfew, he and Kain suddenly appear and Yuki becomes alert. Yuki was afraid of what they might do to those girls but Aidou tells her that they came especially to see Yuki. Yuki swung down from a tree and scraped open her hands, and the scent of her blood attracted them. Aidou licks the blood off her hand. Luckily, the two girls fainted and were taken to the chairman to have their memories modified. Aidou is not overtly fond of Yuki and dislikes the attention that Kaname gives her, but tolerates her presence because Kaname loves her. He has difficulty showing her respect, often calling her "Yuki Cross" or just "Hey, you", but becomes willing to protect her for Kaname's sake when Kaname announces that she is to be his lover. Aidou eventually develops an understanding for Yuki when she claims that she will remain loyal to Kaname, regardless of what he says or does. When Yuki is revealed to be a pureblood vampire of the Kuran line, Aidou has difficulty adjusting himself to referring to her in a formal manner and frequently corrects himself. While Aidou is the only one to witness Kaname killing Shizuka Hiou, he remains loyal to Kaname and willing to lend Kaname his power in order to help find the killers of Kaname's parents. Though Kaname declines Aidou's help in order to prevent Aidou from putting himself in danger, Aidou continues to investigate behind Kaname's back in order to discover possible enemies of the Kuran family and secrets that Kaname has hidden.
