Akitaru Oubi is a 31-year-old male standing 189 cm tall and weighing 108 kg, born on March 27 with blood type B. He serves as the founding captain of Special Fire Force Company 8, leading investigations into spontaneous human combustion and corruption within other fire force companies. Though lacking pyrokinetic abilities, he maintains exceptional physical strength through constant training, routinely carrying over 30 kg of specialized equipment during missions. His personality blends approachability with strong principles. He displays a nonchalant attitude toward minor disruptions but exhibits zero tolerance for disrespect toward victims' families or the deceased, viewing infernal purification as necessary yet tragic. This ethical stance drives his deep compassion for bereaved relatives, prioritizing the retrieval of personal mementos for survivors—even risking his life to save a family photograph during a rescue. Physical training serves as both practical preparation and personal routine, often exercising during meetings or conversations. Combat relies on tactical ingenuity and specialized Haijima Industries equipment rather than supernatural powers. Standard tools include the Core Annihilating Pile Bunker, firefighting axes, electromagnetic orbs for ability disruption, and flame-extinguishing grenades. He demonstrates strategic adaptability, improvising with environmental objects like train tracks. Though recognized with two commendations during his Fire Defence Agency service, both were revoked for prioritizing civilian rescue over orders. Benimaru Shinmon describes his capacity for "hysterical strength," enabling feats like breaking metal chains barehanded or hardening muscles against piercing attacks. His motivation stems from witnessing systemic failure as a conventional firefighter. Seeing the Fire Force prioritize infernals via a point system while ignoring victims' families prompted him to steal equipment and eliminate one threat alongside Takehisa Hinawa. This act catalyzed Company 8's establishment, recruiting Hinawa as first officer. His leadership inspires intense loyalty despite members' eccentricities, with adversaries acknowledging his moral integrity. Character development includes significant physical and organizational evolution. Confronting the White-Clad's Assault resulted in near-fatal injuries reversed by allies. During the Great Cataclysm, his death at a doppelgänger's hands triggered Shinra Kusakabe's emotional collapse, though world recreation restored him. Post-cataclysm, he dissolved the Fire Force to establish the World Heroes Force, rising to battalion commander and later president within 25 years, progressing from company captain to global leadership. Physically, he has a muscular build with short, dark hair shaven at the sides. Standard bunker gear includes flame-resistant uniforms with blue insignia, helmets featuring retractable face shields, and Company 8 patches. Off-duty, he wears simple grey jumpsuits. Preferences include favorite foods like ramen (disliking protein supplements), rock music, dogs, and the color beige. Hobbies encompass record collecting, basketball, and DIY projects despite limited proficiency.
