Kishibe is the top Devil Hunter in Japan in the Chainsaw Man series. Starting his career as a cocky but promising recruit, his years as a Devil Hunter wore away at both his brashness and his body, leaving him with a distinctive Glasgow Grin on half of his face.

Due to his expertise, he serves as a mentor for Public Safety's most promising recruits, and has trained some of the most.
