Akatsuki Kain

Akatsuk'i Kain ('カイン 暁, Kain Akatsuki) is Hanabusa Aido's cousin and one of "Kaname-sama's right hands." His nickname is "Wild," despite his mellow personality.

Appearance
Kain has a muscular build and a formidable height of 188cm, the tallest vampire of the Night Class bunch. He seemingly lacks the classically pale vampire complexion. He has strawberry blond short wavy hair and amber eyes. Kain also wears one silver earring in his left ear and always wears his shirt unbuttoned, contributing to his reputation as "Wild". He has a tattoo in the pattern of a flame on his left hip..

Personality
Akatsuki Kain is a calm person who rarely loses his cool, and often needs to reign in impulsive Hanabusa and Ruka. He is incredibly perceptive and is frequently sensitive to others' feelings. His association with Aido frequently sees him getting into trouble, despite not being directly responsible. He refers to Kaname Kuran as their "gang leader." He is also loyal and protective; the type who would never betray his friends. In 48th Night, he reveals that he believes in Kaname because Ruka does, but someday hopes to believe in himself.

Background
Akatsuki grew up within a noble family, the Kain family, which was pro-monarchy. 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 cousins, Hanabusa Aido, 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 meet again until years later. Not much is known about his parentage. His original intent in attending Cross Academy was to take care of Hanabusa and Ruka. In the Moon Dorm, he is roommates with Hanabusa Aido.

Story summary
He first suspected Zero of killing Shizuka and reported the facts to Kaname as he knew them. During the attack on the night class, he accompanies Ruka and protects the day class students. When they question what the Night Class are, he promises to tell them later. When Hanabusa fails to get Kaname's location after the attack, he heads back home with Ruka and Hanbusa. During the following year, he appears to now act as Kaname's messenger and remains one of his right-hand men.

Ruka Souen
Kain holds an unrequited love for Ruka Souen and loyally follows her in whatever path she chooses. His strong love for her stops him from having a complete loyalty to Kaname Kuran, as Kain once told him that he would never forgive Kaname if he hurt Ruka.

Powers
Like all aristocrat vampires, Akatsuki has accelerated healing. Akatsuki possesses the opposite power to his cousin with the ability to conjure and control fire.
