In a world where spontaneous human combustion turns individuals into flame-wielding Infernals, the Tokyo Empire is protected by specialized firefighting brigades known as the Fire Force. These brigades combat Infernals and investigate the phenomenon of spontaneous combustion, which threatens humanity. The story centers on Shinra Kusakabe, a third-generation pyrokinetic known as a Devil’s Footprint for his ability to ignite flames from his feet. Shinra joins Special Fire Force Company 8, a unit dedicated to uncovering the truth behind the Infernal outbreaks and the mysterious Evangelist, a shadowy figure orchestrating the chaos.

Company 8, led by Akitaru Ōbi, operates independently to investigate corruption within the Fire Force and the Holy Sol Temple, the religious organization governing the empire. Shinra’s abilities and determination make him a key figure in the fight against Infernals, but his past is intertwined with the mysteries of the phenomenon. His younger brother, Shō Kusakabe, is revealed to be a member of the White-Clad, a cult serving the Evangelist, creating a personal conflict for Shinra as he seeks to save his brother and uncover the truth.

The narrative explores the origins of spontaneous combustion, linking it to the Adolla Burst, a rare and powerful pyrokinetic ability possessed by individuals like Shinra and Shō. The Adolla Burst is tied to the Evangelist’s plan to reshape the world through the Great Cataclysm, a catastrophic event that threatens to engulf humanity in flames. As Company 8 investigates, they uncover layers of conspiracy involving the Fire Force, the Holy Sol Temple, and the White-Clad, revealing a complex web of betrayal and manipulation.

Key characters include Arthur Boyle, Shinra’s rival and fellow Company 8 member, who wields a plasma sword and embodies a chivalric persona; Maki Oze, a second-generation pyrokinetic with exceptional physical strength; and Iris, a nun who provides spiritual support to the team. The series balances action-packed battles with moments of camaraderie and introspection, delving into themes of faith, identity, and the consequences of power. As the story progresses, Shinra and his allies confront increasingly powerful adversaries, including the White-Clad’s leaders and the enigmatic Evangelist, while striving to prevent the impending apocalypse.
