Torajirō, alias Bareknuckle Tiger, is a former yakuza boss and underworld legend. He stood as the sole acknowledged rival to Tatsu, the "Immortal Dragon," matching him in raw power and ferocity. His formidable combat skills earned him the moniker "Steelfist Tiger."

Imprisonment severed his ties to his clan. Released, he discovered Tatsu had dismantled his gang. Choosing not to pursue vengeance, Torajirō abandoned crime. He launched a one-man food truck business, starting with crêpes and later adding bubble tea. He approaches food preparation with the same intense seriousness and meticulousness he once applied to yakuza activities, displaying exceptional dexterity.

Torajirō retains a heavy, tank-like muscular build from his past. His appearance features fair hair and eyebrows, marked by a distinctive long, thin scar crossing the bridge of his nose and both cheeks. Yakuza tattoos cover his pectorals, shoulders, and forearms, enhancing his imposing presence.

While initially resentful toward Tatsu for destroying his clan, Torajirō moved beyond outright hostility. They settled their grudge through a non-violent "food war," transforming their competitive spirit into a culinary rivalry. Torajirō developed a begrudging respect for Tatsu's dedication to domestic life, despite initial incomprehension. Their shared history as ex-yakuza and mutual passion for food and confectionery created unexpected common ground. This forged a complex dynamic blending rivalry with camaraderie, evident when Torajirō sought Tatsu's insights on trends like bubble tea to boost his business.

Across manga, anime, and live-action adaptations, Torajirō remains a reformed ex-gangster dedicated to his food truck. Kenichi Takitō portrays him in the live-action drama. His character arc consistently emphasizes adaptation and resilience, finding contentment in his new life as a small business owner, leaving violence behind.
