Hanabusa Aido

Aido Hanabusa (藍堂 花房, Hanabusa Aidō?), nicknamed "Idol" by the Day Class girls, he along with his cousin Kain, Aidou is known among the Night Class as "Kaname-sama's right hand" and has a fierce admiration for Kaname that borders on zealousness. Aidou is a noble-class vampire and possesses the ability to conjure and control ice.

Personality
Though he appears cheerful and friendly one moment, he can quickly become vindictive and cruel the next and tends to be outspoken, stubborn, reckless, hot-headed and out of line. Though very loyal to Kaname, he has a tendency to overstep his boundaries, which results in Kaname punishing him, if discovered. Aidou was the one that figured out Zero is a vampire, though he keeps this information to himself without any hidden agenda. He is very cunning to uncover many things, like the reason why Kaname's parents were murdered.

Appearance
Aidō, possesses wavy blonde hair and eyes that are remotely close to turquoise. His height is 177 cm and has pale skin like most of the vampires.

Background
Aidō is not overtly fond of Yuki and dislikes the attention that Kaname gives her. He is temporarily troubled when he witnesses Kaname's killing of a fellow pureblood and runs away from the Moon Dormitory and imposes himself on Yuki and Zero. Agreeing with Yuki's assertion that he would remain loyal to Kaname even if betrayed by Kaname, he returns to the vampire's side. Aido has difficulty adjusting himself to referring to Yuki in a formal manner following the revelation of her true nature when he is appointed as one of her protectors.

Plot Summary
Because of Aidou's stubbornness, he tends to go out of line. 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 Yuuki 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 bites her hand, and drinks her blood. He was going to bite her neck but is stopped by Zero Kiryuu. Luckily, the two girls fainted and were taken to the chairman to have their memories modified.

Currently riding on a train, he, Ruka and Akatsuki are on their way home to see their families for a little while, after deciding that they would search for Kaname and Yuuki after their short visit.

After the one year time skip, Aidō is seen to be Yuuki's personal teacher.
