Rekka Hoshimiya serves as a lieutenant in Special Fire Force Company 1, masquerading as a Holy Sol Temple priest. His striking features—spiky dark-red hair, star-shaped pupils, and a muscular frame—complement his dark cassock and cross pendant. Orphaned early, his fiery energy and rigid moral code drew Sister Sumire’s attention, funneling him into Company 1. There, he forged alliances with Karim Flam and Huo Yan Li, their opposing temperaments clashing yet coalescing into camaraderie. Publicly, his charisma galvanized followers like Tamaki Kotatsu, painting him as a heroic ideal. Secretly, Rekka pledged loyalty to the White-Clad cult, advancing their apocalyptic agenda through covert experiments. He implanted parasitic "bugs" into victims to engineer artificial Infernals, hunting Adolla Burst candidates. His ruthless testing targeted children, including Nataku Son, whose infection left deep psychological scars. In combat, Rekka wielded Third Generation pyrokinesis, flames erupting from his arms to fuel his Star Fist Punch—a martial technique amplified by explosive fire propulsion. Obsession drove him to recklessness during a clash with Shinra Kusakabe, searing his arms beyond use. Karim’s ice manipulation halted his rampage, and Arrow, a White-Clad assassin, silenced him to protect cult secrets. Rekka’s death triggered cascading repercussions. Karim allied with Company 8 to unravel his betrayal, while Nataku battled hallucinations of Rekka prodding him toward destruction—a torment amplified by Haumea’s psychic meddling. Temporal distortions during the Great Cataclysm briefly resurrected Rekka, though this anomaly hinged on reality’s unraveling. A later doppelgänger emerged, mirroring his fanaticism and tactics to manipulate others toward despair, until Karim dismantled the mimic. Rekka’s legacy lingers in Nataku’s trauma, the ethical fractures among former allies, and the shadow he cast over the Fire Force’s struggle, igniting conflicts that ripple through the narrative’s core.
