The American Thugs are three brothers turned contract killers from the United States, dispatched to Japan to capture Denji's chainsaw heart and convinced by a lifetime of close calls that nothing can ever kill them.

The Anti-Makima Squad is a covert task force of soldiers and devil hunters assembled under Kishibe with a single purpose: to bring down Makima by any means, even a suicide pact that banishes her to Hell.

Publicly the Chainsaw Man Church hails Chainsaw Man as the savior destined to hold back a coming age of devils. In secret, its founders mean to feed their own believers to slaughter, stoking the public terror needed to make Chainsaw Man and War strong enough to kill the Death Devil.

Devil Hunters are the people, most of them human but some fiend or hybrid, who take it upon themselves to battle the devils that threaten the world. They typically arm themselves by striking contracts with devils, gaining an edge against monsters that ordinary law enforcement could never hope to match.

The Devil Hunter Club is a high school society at Fourth East where students band together to track and slay devils, doubling as the student council and serving as the springboard that funnels many of its members into the Chainsaw Man Church.

A quartet of devils so formidable that only Chainsaw Man and a handful of Primal Fears can rival them, the Horsemen disguise themselves as human women and regard one another as sisters. Having once warred together against Chainsaw Man in Hell, the four, namely War, Death, Famine, and Control, now chase clashing goals that all loop back to him.

Quanxi and the Fiends is a Chinese assassination team made up of the legendary hunter Quanxi and the four fiends she keeps as her lovers, sent to Japan to claim Denji's heart.

Tokyo Special Division 4 was Makima's experimental Public Safety unit, a deliberately mixed squad of humans, fiends, devils, and hybrids treated as powerful but expendable assets.

Tokyo Special Division 5 was a Public Safety subdivision Makima built from the Weapon Hybrids she controlled, reassembling the old enemies of the Chainsaw Devil for one last attempt to bring him down.

The Weapon Devils were a band of seven devils, each personifying a kind of weapon, that once fought under the Four Horsemen and have since all merged with humans to become the Weapon Hybrids.

Recurring villains in Chainsaw Man, the Yakuza are a web of organized crime syndicates rooted in Japan. Run with rigid discipline and built on illegal trade, they profit by pushing desperate people into hunting Devils on their behalf.
