When Wakako (Takeda Rina) asks the depressed Chief Okada (Shiotsuka Kohei) why, he says that his daughter called him old-fashioned for a certain reason. From there, the conversation turns to "Showaism"... Obsessed with the Showa era, Wakako finds a retro izakaya on her way home from work and stops in. She enjoys simple dishes like pickled vegetables and ham cutlets with draft beer, but is captivated by something a nearby customer is eating with relish. Completely engrossed in Showa retro, Wakako goes on a special Showa-era hopping spree in Oimachi, which Okada had told her about, on another day.
