The Kiryus (Zero and Ichiru's parents)

Personality
No one knows much of their personalities, but they both love their sons.

History
Both Kiryu's were high-ranking Vampire Hunters, and are the parents of Zero and Ichiru Kiryu. Despite loving both their sons dearly, the Kiryu's felt Ichiru's illness and lack of natural talent in comparison to Zero would prevent him from becoming a Hunter. For this reason, they focused more of their time on developing Zero's skills as a Hunter, giving Ichiru the impression they favored Zero over him. Ichiru's resentment over his parents' seemingly preferential treatment of his brother would have tragic consequences later on and lead to the destruction of the Kiryu family. These events would be set in motion the night the Kiryus were assigned to kill an ex-human vampire who they'd been told had fallen to Level E. Unfortunately, the Kiryus were lied to and had been used as pawns by Rido Kuran to kill the ex-human vampire who had become his fiancée, Shizuka Hio's lover. Shizuka's grief over the death of her lover would drive her to insanity, and later, to revenge. With the assistance of Ichiru, who had become captivated by her, Shizuka killed both Kiryu's, turned Zero into a vampire, and took Ichiru away.
