Taisou, a superhuman esper within the International Police Organisation’s Experts of Justice, stands among the Big Nine—elite warriors whose power challenges the Magnificent Ten. His body generates electrical energy, channeled into martial arts like the "Funshaken" (Jet Fist) for explosive strikes, and repurposed to power critical systems in emergencies. A gourd strapped to his side doubles as both a sake container and a tool to focus his energy, its contents aiding communication and combat precision.

His history intertwines with Alberto the Impact of the Magnificent Ten, their rivalry ignited when Taisou was accused of causing Alberto’s friend Cervantes’ death and the loss of Alberto’s right eye. Though adversaries, they clash with grudging respect. Beyond battle, Taisou mentors Daisaku Kusama, a young protégé he guides with paternal sternness and idealism, while sharing a brotherly bond with Tetsugyu, a fellow Expert of Justice who reveres him as "aniki."

At Interpol’s Peking base, Taisou endures grave injuries repelling Alberto’s assault, yet channels his waning strength to revive the base’s power grid. Later, in Shanghai, he volunteers to sustain a magnetic web containing the cataclysmic Eye of Volger, aware Alberto seeks vengeance. Their final duel leaves Taisou mortally wounded, but his electrical surge ensures the web holds long enough for allies to flee. He dies in Shanghai’s annihilation, consumed by the Eye’s blast.

His sacrifice galvanizes Daisaku and Tetsugyu, shaping their resolve. Married to Youshi, a blue-skinned warrior and mission partner, their union blends combat synergy and mutual respect, her steady presence tempering his impulsiveness. Spin-offs like *Giant Robo Gaiden Ginrei* reference his legacy, though specifics are sparse. Across narratives, Taisou emerges as a flawed hero: a pillar of raw power and humanity, his choices etching duty and sacrifice into the lives he shaped.
