How Kairi joined the Tourney
Kairi was born to the main house of the Mizukami family and was trained in the family's ancient art of hand-to-hand combat. However, Kairi lost his memories when he fought his own father to a fight to the death and for several years he has wandered the world, fighting without rhyme or reason. Only the words "you must challenge your limits" remained in his memories. Led by these words, Kairi thought that the only way to recover his memories was to follow the way of the Shura (修羅?) and fight, replacing his lost memories with the nature of a demon. As he continued fighting, Kairi's hair was turned from black to white and his body began to be covered in scars. Eventually Kairi fought his younger sister Hokuto on several occasions. Despite the attempts of Nanase, the youngest of siblings to stop them, this has been unavoidable fate for Kairi and Hokuto.
With Hokuto under the Seal of Blood, Kairi prepares for his final battle against his sister. Suddenly, another woman named Aoi Umenokoji steps in his path to try and stop the blood from being spilled.
