Akatsuki Kain

Akatsuki Kain is Hanabusa Aido's cousin and one of "Kaname-sama's right hands". His carefree attitude gets both him and Aido in trouble at times. His nickname is "Wild", despite the fact he is actually mellower than his cousin.

Personality
Akatsuki is always a calm person. He is also a peacekeeper in the Moon Dorm. Akatsuki holds an unrequited love for Ruka (who views him as her best friend only,) and loyally follows her in whatever path she chooses. He has only lost his patience when Ruka has been in danger and told Kaname Kuran that he would never forgive him if Kaname hurt Ruka. He is incredibly perceptive and is frequently sensitive to others' feelings, most particularly with Aidou and Ruka's. He is also loyal and protective, and will never betray his friends.

Appearance
Akatsuki has a muscular build and is very tall, note that he is the tallest vampire out of the Night Class bunch. His height is 189 cm. He is very handsome. His skin does not seem very pale, unlike the other vampires. He has short wavy hair, sometimes looks spiky, his hair color is a very light orange, he has very beautiful and attractive amber eyes. Akatsuki also wears one silver earring in his left ear. He always wears his shirt unbuttoned and this is one of reasons that he is called Wild.

Background
Akatsuki grew up within a noble family. His family is part of what is referred to by Asato Ichijo as the “Aido faction”, presumably comprised of the Aido, Souen, Kain, and other related clans. He is very close to his cousin, Hanabusa Aidou, and Ruka Souen, having been with them since early childhood. He and the other two children met Kaname once when they were children, but did not met again until years later. Not much is known about his parentage it is also unknown why Akatsuki came to Cross Academy. He is also right hand man, along with Hanabusa.

He tends to get blamed for the actions of other vampires (especially Aido) despite not being involved, and ends up getting punished as a result. He also refers to Kaname as their "gang leader". He first suspected Zero of killing Shizuka, but almost instantly realized that was not what had happened. Kain's ability is the opposite of Aidou's, which is the power of fire, he is seen killing off the Level E vampires that are attacking the Day Class students after Rido Kuran's awakening. Currently riding on a train, he, Ruka, and Aidou 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.
