Kain Daisuke (大輔禍因 Great Helper, Cause of Trouble) was a compatriot of Katsumi Scarlet, Chū Mankō and Jiro Kamiko. However; the latter's rebellion had caused Chū's death, creating a situation in which Kain's sanity had been lost, causing him to become a Fallen Reikon Kyuuban. It was not till many weeks later that Kain had returned to sanity and became a new man.
