Akitaru Ōbi commands Special Fire Force Company 8, leading its crusade against spontaneous human combustion and the shadowy forces perpetuating the crisis. A decorated veteran of the Fire Defence Agency, he shifted his career after witnessing the callous disregard of other units toward grieving families of Infernal victims. Driven by this moral awakening, he co-founded Company 8 with Takehisa Hinawa to dismantle systemic corruption, prioritizing empathy and justice over cold protocol. Standing 189 cm tall and weighing 108 kg, his formidable physique masks no pyrokinetic gifts. Instead, he relies on relentless physical training to bridge this gap, honing peak strength and endurance. His combat ingenuity merges specialized weaponry—Core Annihilating Pile Bunker, fire axes—with environmental manipulation, using train tracks or extinguishing foam to destabilize foes. Even Benimaru Shinmon, a pillar of martial prowess, acknowledged his capacity to harness “hysterical strength,” pushing past mortal limits to withstand brutal assaults. He approaches the eradication of Infernals as an ethically fraught duty, demanding respect for survivors’ anguish. This conviction once drove him to brave lethal hazards mid-mission, retrieving a family photograph for a mourning daughter. His leadership cultivates fierce loyalty in Company 8, with subordinates rallying behind his humility and willingness to sacrifice. Allies like Joker and rivals like Hibana commend his unyielding integrity, though Hibana occasionally questions his strategic subtlety. His past reveals a pattern of insubordination for civilian safety, costing him official accolades. A defining moment arose when he encountered a widow whose husband’s Infernal transformation was met with institutional apathy. Partnering with Hinawa to aid her, he cemented Company 8’s dual mandate: halting combustion outbreaks and exposing the rot within their own ranks. In missions, he orchestrates adaptive strategies, from collaborating with engineer Vulcan Joseph to shield Lisa Isaribi using improvised bulletproof armor, to aiding Asakusa’s reconstruction after Benimaru’s clash. Later, he infiltrates the Netherworld to disrupt the White Clad’s combustion conspiracy. Following global upheaval, he ascends to command the World Heroes Force, safeguarding humanity’s rebirth. Beyond duty, he favors ramen, rock anthems, and DIY projects, maintaining a weightlifting regimen. His blood type B and 29-cm foot size round out the trivia of a man as grounded in routine as he is in heroism.
