Ishimaru

As a member of a bandit group involved in human trafficking, he was pursuing the children who had been freed by Tauemon. He followed them all the way to Ama-no-ukihashi, but at the beginning of the story, he was kicked off the bridge by Sakuna-hime and went missing. However, he later reappears as a central figure among the Oni forces, becoming an enemy to Sakuna-hime and her companions. He is extremely prideful, unwilling to trust or rely on others, and does not hesitate to sacrifice his subordinates if it serves his own goals.
