History
Ten years before the start of the story, he and his brothers were caught in a large fire during a revolt. He, his brother Hakuren, and their father, Hakutoku, all died during this incident.

Pirates Arc
He is seen in Hakuryuu's memories. He is with his brothers, fighting against Al-Thamen in the palace, which has been set on fire. Hakuyuu says that he can neither die nor let them have their way. Hakuryuu wonders if their mother and Hakuei are alright, but his brothers don't answer. After Hakuren dies, Hakuyuu is also badly wounded, and laments that this is the end for them both before telling Hakuryuu that he must survive and take revenge. He then informs Hakuryuu that the one who wanted to kill them is none other than Gyokuen, and then stabs himself, drenching the little boy in blood to protect him from the flames.
