Manga version
A pervert and a highly dishonorable fighter but still one of the Four Devas. He specialises in using a pair of tonfas with hidden blades. Myosai used a pressure point move on him that would kill him in ten days. She promised to remove the effect if Kannei would kill Hakufu but he has failed to do this so far. He interrupts the Seito group's attack during the battle, having been possessed by Ryofu's magatama. He shows none of her personality, but has her vicious will to fight. He is finally stopped by Taishiji.
Anime version
He is crazier in the anime than in the manga and can be best described as a deranged chimpanzee. Saji drives him insane by making him kill Enjutsu. He then hypnotizes Kannei into believing Enjutsu is still alive and gives him orders which he suicidally follows. He is confined to an asylum at the end of the first season where he still remains. However, after Bashoku's framing of Kannei for the death of Kakuka, he mysteriously vanished from this confinement, which lead Koukin and Gakushuu into suspecting Seito may have been involved.
