It's a day in the life of your average househusband--if your average househusband is the legendary yakuza "the Immortal Dragon"! 
A former yakuza legend leaves it all behind to become your everyday househusband. But it's not easy to walk away from the gangster life, and what should be mundane household tasks are anything but! 
On what begins as just another shopping trip, Tatsu has a run-in with a thief--of the feline persuasion! When the gangster-turned-homemaker gives chase, yakuza are quickly drawn into the fray, and chaos erupts in the streets of the shopping district. Even everyday errands can turn treacherous when you're the Immortal Dragon!
