Toragorō Onigawara, known as "Onitora" (Chief), directs the International Secret Police Agency, spearheading global operations against crime. His commanding presence, accentuated by a striking mustache, mirrors his unwavering dedication to justice—though his missions frequently spiral into chaotic mishaps or dangerous predicaments, forcing the superhero Polymar to intervene. Determined to mold his son Takeshi into an elite investigator, Toragorō’s rigid methods clashed with Takeshi’s unconventional instincts, culminating in their estrangement. Privately, he agonizes over Takeshi’s unexplained absences, oblivious to his son’s double life as Polymar. The revelation of this secret bridges their rift, prompting Toragorō to tacitly endorse Takeshi’s dual existence as both detective aide and masked vigilante. Despite a penchant for blunders, Toragorō exhibits cunning foresight, devising clever tactics to corner foes. His authority over law enforcement remains tenuous, with his teams habitually arriving post-conflict to find Polymar victorious. This blend of hapless misadventures and unyielding integrity cements his role as a paradoxical leader—equally defined by earnest resolve and inadvertent comedy.
