Torajirō is a former yakuza boss whose gang was dismantled by Tatsu during his incarceration. After prison release, he retired from crime and now operates a crêpe food truck. He maintains a competitive rivalry with Tatsu, extending into domestic tasks and culinary endeavors.

He approaches his new profession with the intensity of his yakuza past, treating crêpe sales with extreme competitiveness. Torajirō actively challenges rival food vendors to assert dominance, persistently driven to prove himself the best. Despite their adversarial history, he and Tatsu share an interest in food preparation and confectionery, occasionally providing neutral ground for their interactions.

Physically, Torajirō bears visible scars and tattoos from his former life. He often wears a bandana, aligning with his working-class profession and rugged appearance. His personality blends a confrontational streak with social awkwardness, evident in exaggerated approaches to ordinary situations.

In the live-action drama adaptation, Torajirō is portrayed by Kenichi Takitō. His role consistently serves as a foil to Tatsu, emphasizing the theme of reformed yakuza navigating civilian life through humor and rivalry.
