S1, E1: Reinya works as the poster girl for convenience store Faminya by day and steals golden treasures as Phantom Theif Reinya by night. With her sidekick Chutaro, Reinya plays a slapstick game of cat-and-mouse with the perverted Captain, the delusional Detective, and Nocchi of the Oedo Police Department. The Golden Umakabai, a solid gold statue of a local instant noodle brand, is scheduled to go on display at the Hakata Museum. Following her motto “nothing is greater than gold,” Reinya decides to snatch this golden treasure. However, the Captain, the Detective, and Nocchi are on full alert for Reinya at the museum.
