Tatsu, The Immortal Dragon is back at his antics.  He's brandishing a bottle of bug spray against The Black Bullet - a cockroach - who has been sent by an unknown enemy group.  Later, he takes a gig serving food in a restaurant to some really jumpy gentlemen who are probably still in the business.  Bargain hunting at the supermarket is made even more entertaining when a down-and-out mob boss' wife takes a job as a checker and double charges Tatsu for an item.  Tatsu tries to help his wife Miku relax after several long days at work, and he of course takes it to the Nth degree.  A touching reunion with his former boss allows The Immortal Dragon to show his domestic side to the fearsome former head of the Yakuza Crime family.
