Devil Hunter Club

Based at Fourth East High School, this student organization gathers pupils eager to hunt devils, sending them out on patrols to cull as many as they can locate. Admission demands an initiation in which a group of three first-years must retrieve a slain devil within a single week. The club overlaps heavily with the school's student council, so much so that its president, Haruka Iseumi, habitually called it the student council slash Devil Hunter Club. It is one of many such clubs that sprang up across schools as public fascination with devils grew.

Asa Mitaka and Yoru signed up hoping to locate the Chainsaw Man, whose host was rumored to attend their school. The pair were paired with Yuko and Hirofumi Yoshida for the initiation ritual. When Yuko later went berserk and tore through the school in her transformed state, several members, Seigi Akoku and Furio among them, moved to stop her. Fami, the Famine Devil hidden within the club, stepped in to heal Yuko after Asa had nearly killed her, having called herself Asa's sister. Following the fight, the president Haruka praised Asa for standing against Yuko and invited her to join, even revealing a pull cord in his chest. Mistaking him for Chainsaw Man, Yoru promptly departed. In time, a great many of the club's members would migrate into the Chainsaw Man Church.

Haruka Iseumi presides over the club and remains alive. Its membership has included Asa Mitaka and Yoru, the disguised Famine Devil Fami, Hirofumi Yoshida, Nobana Higashiyama, and Seigi Akoku, along with the deceased Furio and Yuko, plus several unnamed students.
