His history in nabari

The Shimizu Clan was a family of samurai who worked to provide a balance between Nabari and the outside world. They didn't involve themselves in conflicts between clans and only interfered when people from the surface world were endangered by ninjas from Nabari. Raikou and his little sister Raimei were raised as heirs to the clan. The clan was led by their mother, a woman originally from Fuuma who became the clan's head after defeating all of the members battle.

The clan was not without conflicts of their own, Raikou and Raimei's uncle, Iroku, wanted to take over, so that the clan could become more active in the world of Nabari and the outside world, so they could save people rather than just keep balance. Raikou agreed, and joined his cause because, he was unable to save one of his friends from being killed by thugs. Eventually the whole clan stood against Raikou's parents, and although Raikou had been told it would be non-violent, the other clan members killed Raikou's sickly father who couldn't defend himself. When Raikou tried to stop him, his uncle lashed out and tried to kill him, but hit his mother instead. As she was dying she told Raikou to use the clan head's sword to stop them, and punish them for their horrible acts. Raikou killed them, but his sister only saw the end result, and believed Raikou had massacred the entire clan for his own benefit.

Raikou was in high school when he killed his family. I think that Raikou blames himself for what happened to his parents. I feel that the reason he refuses to talk about the situation because he feels taking the blame for his parents' deaths should be his punishment for not stopping his uncle sooner. Raikou often visits the site where their house once stood and pays his respects to his family. When he joined Kairōshū he did so with the intention of seeking a new justice, because he felt that he would be helping to create and restore the balance in the world of Nabari.
