Infernals (Fire Force)

The Infernals are a species that feature in Fire Force.

History

The Infernals (Japanese: 焰ビト, Hepburn: Homura Bito) were humans that suffered from Spontaneous Human Combustion where they became rabid pyrokinetic beings. The Infernals were first revealed as the tragic consequence of spontaneous human combustion, an unexplained phenomenon in which ordinary people erupted into flames and transformed into monstrous beings. Rather than burning to ash, the afflicted mutated into creatures of living fire, their bodies warped beyond recognition as they lost all traces of their humanity. This event marked the central crisis of the world, with Infernals representing both a natural disaster and a supernatural threat. Unlike ordinary fires, Infernals were immortal until exorcised, continuing to burn endlessly while wreaking destruction upon their surroundings. The first generation of these creatures were not born with control over flames, but rather consumed by them, serving as unwilling engines of chaos. Rather than a singular catastrophic event, their creation was revealed to be ongoing, with new victims combusting unpredictably across the city. These Infernals often retained faint vestiges of their original selves, sometimes staying near loved ones or haunting the places they cherished, though their minds were almost entirely gone. This made their destruction by the Special Fire Force both a rescue and a mercy, as exorcising them was the only way to release their trapped souls. In combat, they showed varying degrees of ferocity—some rampaging uncontrollably through city streets, others standing nearly still as if lost in memory, but all radiating destructive fire that threatened everything nearby.

A passenger on a train carriage suddenly succumbed to the Spontaneous Human Combustion phenomenon, his body erupting in a violent surge of orange and black flames that quickly consumed his humanity. As the fire took hold, he ceased to be a man and became a core of concentrated heat, his skin charring into a brittle, obsidian-like husk while his eyes glowed with a mindless, destructive intensity. He thrashed wildly against the metal walls, his mere presence melting the interior fixtures and sending a wave of searing agony through the trapped crowd. Despite the primal terror he radiated, his movements were erratic and burdened by the weight of his own combustion, leaving a trail of ash and cinders as he roared into the smoke-filled air. He held his position as a living pyre until the Special Fire Force Company 8 breached the scene, at which point he became the focal point of a grim ritual of 'extinguishment', remaining a relentless force of nature until his core was finally silenced and his soul was offered a final, solemn prayer. Another incident occurred at the private sanctuary of a family home, where a devoted husband and father was tragically transformed into a charcoal-laden beast at his own dining table. Unlike the chaotic outburst on the train, this Infernal sat in a haunting, statuesque silence, his body hardened into a jagged silhouette of soot and glowing embers while his wife and daughter watched in paralyzed horror. When Company 8 arrived at the residence, the creature finally stirred, lashing out with elongated, fiery limbs that charred the wooden architecture and sent plumes of thick, black smoke billowing into the neighborhood sky. He moved with a heavy, mournful aggression, his roar sounding less like a monster and more like a distorted echo of human suffering that vibrated through the cramped hallways. As the ceiling began to buckle under the intense thermal pressure he emitted, he swung blindly at the fire soldiers, acting as a tragic barrier between his former life and the inevitable 'cleansing' that awaited him. He struggled against the freezing impact of the matchbox equipment and the physical strikes of the crew, remaining a searing pillar of grief until a decisive blow shattered his core, finally allowing his scorched remains to crumble into a peaceful heap of ash.

During the mission to the Special Fire Cathedral 5, multiple Infernals functioned as a coordinated defensive line within the industrial facility. These entities maintained stationary positions along the corridors, utilizing their heat-convection abilities to raise the ambient temperature and create environmental hazards for the advancing Special Fire Force Company 8. One specific Infernal, formerly a high-ranking member of the priesthood, retained a seated posture while emitting continuous bursts of high-intensity flames from its torso to repel intruders. Unlike the spontaneous combustion cases in the previous sector, these units demonstrated a rudimentary level of tactical positioning, acting as biological sentries to guard the inner sanctum of the cathedral. When engaged in direct combat, the Infernals lashed out with elongated, charred limbs and projected concentrated streams of fire to intercept kinetic projectiles and physical strikes. They sustained a high volume of structural damage from pressurized water and thermal-dampening equipment without retreating, maintaining their defensive perimeter until their core structures were physically pierced and extinguished by the specialized weaponry of the opposing fire soldiers.

During the investigation into the 1st Special Fire Brigade, multiple Infernals were artificially induced within the residential and industrial sectors of the Shinjuku District. These entities functioned as a localized diversion, manifesting spontaneously in public areas to initiate high-intensity thermal expansion and structural fires. One specific Infernal, characterized by a multi-armed physiology, utilized its increased limb count to launch simultaneous kinetic strikes against Special Fire Force personnel while projecting continuous streams of concentrated flame from its torso. This entity demonstrated an elevated level of physical durability, resisting initial cooling measures and physical blunt-force trauma to maintain its offensive. Simultaneously, several smaller Infernals occupied the surrounding rooftops and alleyways, acting as environmental hazards that restricted the movement of emergency responders through the emission of black smoke and high-temperature radiation. When engaged by specialized fire-fighting units, these Infernals maintained a relentless forward advancement, ignoring structural damage to their charred exteriors until their cores were directly targeted and neutralized by high-velocity thermal strikes. The entities remained active within the district, forcing a multi-point containment strategy from the combined Fire Force companies to prevent the total incineration of the urban infrastructure.

Later encounters revealed that Infernals were not simply random tragedies but part of a deeper conspiracy tied to the Evangelist and her followers. The White-Clad cult deliberately induced spontaneous human combustion in targeted individuals, weaponizing Infernals as both soldiers and terror tactics. These man-made Infernals were often stronger than naturally occurring ones, sometimes showing coordinated behavior or monstrous mutations beyond the standard fire-wreathed form. The revelation that Infernals could be artificially created reframed them not as a natural disaster alone but as the result of deliberate manipulation, raising the stakes for the Fire Force’s mission and the victims’ suffering.

Overview

In appearance, Infernals were humanoid creatures enveloped in constant, raging flames, their skin scorched black or red and their features distorted by fire. Many bore glowing cracks across their bodies, as though their human forms had been split apart by the heat within. Their faces were often grotesquely frozen, mouths twisted into screams, with glowing eyes burning like embers in the darkness. Some Infernals retained their basic human shapes, while others twisted into hulking monstrosities with oversized limbs or skeletal appearances, depending on the intensity of their transformation. The most striking feature was the perpetual blaze erupting from their bodies, which burned without consuming them, marking them as walking infernos of both tragedy and destruction.

The process of becoming an Infernal began with spontaneous human combustion, a phenomenon that could occur without warning, transforming an ordinary human into a creature of fire within moments. Victims erupted in flames, their humanity stripped away as their bodies twisted and ignited from the inside out. In the case of artificially created Infernals, the White-Clad triggered this combustion deliberately, converting people into monsters at will through secret rituals and technological means. Once the transformation was complete, the victim was no longer capable of returning to human form, condemned to burn until they were destroyed. Only through exorcism by the Special Fire Force could the souls of Infernals be released, making each combat encounter both a fight and a funeral.

The abilities of Infernals stemmed from their nature as living fire. They were immune to heat and flame, their bodies composed of burning energy that could withstand weapons and physical attacks. Many radiated intense heat waves that could ignite surroundings, while stronger types unleashed direct bursts of fire or explosive power from their bodies. Their durability was extraordinary, as conventional means of extinguishing them proved ineffective, requiring specialized pyrokinetic techniques or divine prayers to put them down. Some Infernals were stationary, burning endlessly in place, while others became aggressive predators, hunting and killing humans without hesitation. At their core, Infernals embodied destruction given form, immortal flames that could only be quelled by force and ritual.
