Kaiou

カイオウ

Kaiou is the First Rashou. He declares himself to be the Creator of the New Century and the Demon Kaiou. He is the elder blood brother of Raou and Toki, having stayed in Asura after his brothers left the country during their childhood. He looks very much like Raou, except for an x-shaped scar on his face. Kaiou is depicted as Asura's strongest warrior and is the only character besides Souther to brutally defeat Kenshirou after their first meeting. He wears specially made armor that lets him control his evil aura. He despises the main Hokuto bloodline, from which Ken and Hyou descend, because Jukei forced him into a subordinate role to Hyou despite his superior skills. Kaiou is the last major villain in the manga (though others appear after him) and the final opponent Kenshirou faces in the TV series.
