Formerly a fearsome yakuza, "Immortal Dragon" Tatsu now tackles the trials of everyday existence. While his cherished wife Miku is at work, Tatsu dons his reliable apron, manages their household budget, tracks down the best retail deals, and masters the art of being a househusband with guidance from the neighborhood wives. Even though Tatsu has left his violent past behind, his old associates and foes keep popping up around every corner—though now they serve merely as competitors in domestic pursuits. Amidst a sea of chores to keep him busy, it appears that no matter how difficult things become, Tatsu's relentless determination holds firm as he pours his utmost effort into his duties.
