Shinra Kusakabe, a teenager with spiky black hair, crimson eyes marked by white pupils, and jagged teeth, bears a nervous grin stemming from childhood trauma. Witnessing his mother’s death in a fire at age five triggered this involuntary reaction, branding him a "devil" among peers. The same tragedy ignited his Third Generation pyrokinetic powers, manifesting as flames from his feet that earned him the moniker "Devil’s Footprints." His younger brother Shō vanished during the blaze, later revealed as a kidnapping by the White-Clad cult to exploit infernal disasters. Isolated due to societal fear, Shinra enlisted in the Special Fire Force to honor a childhood vow to his mother: becoming a hero who saves lives. Driven by twin goals—rescuing Shō and unraveling their family’s tragedy—he uncovers his Adolla Burst ability, granting light-speed movement and a tether to Adolla, a primordial dimension linked to creation myths. This power marks him as the Fourth Pillar, a linchpin in the White-Clad’s scheme to trigger a new Great Cataclysm. Balancing impulsiveness with tactical acumen, Shinra routinely risks his life to protect others, clashing with teammate Arthur Boyle while respecting superiors like his captain. His bond with Shō shifts from obsessive protection to reciprocal trust, anchored by shared maternal memories. This connection enables Shinra to forge an Adolla Link, overriding Shō’s defenses. A three-month possession by his Adolla doppelgänger temporarily alters his appearance to white hair, tattoos, and piercings, amplifying aggression. Post-recovery, he regains his original form before evolving into Shinrabanshō-man—a deity-like state with horns, flaming tattoos, and goat-like legs—achieved through familial soul resonance. This fusion of wills fuels his opposition to the Evangelist, the White-Clad’s leader. Mastering reality-warping via Adolla, Shinra defeats the Evangelist and restructures existence by merging Earth with Adolla, eradicating infernals and forging a new societal order. Despite attaining near-divine power, he rejects control over humanity, opting to preserve free will. Public scorn, fallen comrades, and Fire Force corruption strain Shinra’s heroic resolve. Yet he persists, embodying the tension between mortal fragility and cosmic power, ultimately reaffirming his identity not as a god but as a protector who chooses humanity over dominion.
