A househusband who used to run yakuza gangs now obsesses over grocery sales and his wife's lunch box. The comedy lands because every joke lives in Tatsu's face, the way his deadpan yakuza intensity collides with genuinely domestic concerns. This is comfort viewing that doesn't insult your intelligence, where the humor comes from character truth, not forced gags.

The Immortal Dragon has put his life of violence behind him for something far more unpredictable: perfecting the art of homemaking. Tatsu, once a feared yakuza, carries on as a devoted househusband, meeting the challenges of everyday domestic life with the same intensity he once brought to the underworld. A trip to the supermarket becomes a strategic operation as he chases the best sales. While his beloved wife Miku is at work, he puts on his trusted apron, manages the household budget and picks up tips from the neighborhood wives. Former colleagues and old enemies keep turning up, but now only as rivals in homemaking pursuits. The comedy comes from the contrast between his fearsome reputation and the ordinary chores that fill his days, and these five episodes show that however tough things get, Tatsu gives every task his absolute best. Sometimes the hardest battles are not fought with fists at all.
