A retired gangster spends his time as a househusband carrying out home chores.

"Immortal Tatsu," the legendary yakuza who single-handedly defeated a rival gang with a lead pipe, is a name known to strike fear in both hardened police officers and vicious criminals. Soon after his sudden disappearance, he resurfaces with a slight change in profession. Now equipped with an apron, Tatsu has given up violence and is trying to make an honest living as a househusband. While adapting to mundane household tasks, Tatsu finds that being a househusband has its own challenges, from the battlefield known as supermarket sales to failures in the kitchen. He tries to live peacefully, but misunderstandings seem to constantly follow him. "Gokushufudou" follows the daily life of the comically serious ex-yakuza as he leaves behind his dangerous previous life to become a stay-at-home husband.—MAL Rewrite
