Oguro Iwao

Oguro Iwao is an underground vigilante active in Naruhata under the name Knuckleduster. Once a professional hero of extraordinary speed known as O'Clock, he lost his Quirk to All For One and has since fought on using raw physical combat and sharp tactical instincts alone. Driven by his mission to track down illegal drugs circulating in the streets and to rescue his daughter from a dangerous path, he operates in Naruhata while guiding the protagonist Koichi Haimawari, serving as the team's mentor-like spiritual backbone.
