Kujiki is one of the lieutenants in the army of Kamijuu. He is in his early fifties, and is rather old to be a powerful ninja. He is the father of Yomi, the ninja from the Demon Country who revived Mouryou, and is the one who taught him and the Gang of Four their special chakra injection techniques, and most of their jutsu. He has hatred for fellow lieutenant Odayaka, fighting him and, while having unquestionably the more powerful techniques, nearly losing before Kamijuu intervened and stopped the fight. He currently is waiting for Odayaka to become useless, so that he can kill him.
