Rīshiki

Rīshiki (理意識, Rīshiki) is the younger brother of Bīshiki and a child hailing from the Cáo Family. Unlike others within his family, Rīshiki bears an unorthodox genetic mutation that causes his chakra to become incredibly unstable. In his childhood, this lead him to be severely isolated within even his own clan, with everyone abandoning him besides his sister. Unlike others of this ilk, Rīshiki learned and understood the logic behind his isolation from the family, and accepted his fate without remorse.

Learning from this experience, Rīshiki began to apply cold, hard logic towards all the decisions in his life. He understood that, in order to be welcomed back into the clan, he had to demonstrate the ability to control the madness of his chakra, and become a valuable asset. So, with his newfound passion, trained earnestly in the arts of and chakra control in order to return to his place within the clan.

At some point, his elder sister had convinced him to follow down the same path of terrorism she had traveled, leading him to become a member of the terrorist organization ???. Among their ranks, he is regarded as the "White Mist Dragon" (白霧竜, Hakumuryū) due to the nature of his abilities.
