Hanabusa Aido

Hanabusa is a very outgoing and charismatic vampire who is also friendly and cheerful one moment but he can also be cruel the next. He often flirts with the girls, mostly the Day Class students. Hanabusa is careless about keeping the fact that he is a vampire a secret. His actions frequently draw Kaname Kuran's disapproval and he is usually punished for his brashness by the Pureblood. He cares very deeply for his friends and is fiercely loyal to Kaname and Akatsuki Kain. Hanabusa has displayed immense curiosity too, delving deep into the Kuran family's history in an attempt to find out what happened to Kaname's parents ten years ago. In the second season of the manga, he suspects that Kaname is planning something, in which he is hiding from the Night Class students. Reminding Kaname that no matter what, he shall always be on his side, he does not hesitate in finding out more information to the point where the final curtain falls. He is also very observant realizing Zero Kiryu was a vampire and that Kaname did not care to have everyone know. As a child he did not like Kaname, even telling Kaname he hated him. He stated that this was probably because of the attention his siblings were giving him; he thought he was the smartest and most important boy in the entire world. Later, however, he actually confesses his love to Kaname in the midst of what seems to be a party. Hanabusa's intelligence, though often mentioned, is largely downplayed during the story, but appears from time to time. For example, it is Hanabusa who realizes that Maria Kurenai isn't all she seems and who drives his cousin to investigate with him. Hanabusa also guesses that Haruka Kuran and Juri Kuran hadn't committed suicide before Rido Kuran starts to actively move on Cross Academy, and realizes that there is more to Yuki Kuran than Kaname admits in the early part of the story. Hanabusa is also very picky, as shown in the Rido Kuran arc of Vampire Knight.
