A phantom thief who clocks out at the convenience store to plan heists in a basement hideout. The joke writes itself, over and over, because the show never stops finding new angles on the same premise. Every episode is a short, sharp comedy loop: incompetent cops bumbling next door while Reinya's plans either work too well or fall apart in ways that shouldn't be funny but absolutely are.
By day, Reinya stocks shelves at a convenience store like any other teenage employee. By night, she transforms into a master thief orchestrating elaborate heists from her underground hideout, complete with her loyal assistant Chuutarou plotting schemes to pilfer golden treasures across the city. What makes her job easier is the sheer incompetence of her would-be captors: a pervert police inspector more interested in inappropriate behavior than actual police work, a ditzy female officer who couldn't catch a criminal if they walked straight into her arms, and a detective so hopelessly smitten with Reinya that his investigations crumble into lovesick fantasies. Operating right under the noses of the police station next door creates a comic collision course between Reinya's double life and the bumbling trio's failed attempts at law enforcement. The show thrives on slapstick humor and absurdist comedy as this mismatched police force repeatedly blunders their investigations while Reinya executes her gold-stealing schemes. Quick-paced and lighthearted, this short series delivers comedy through the gap between criminal ambition and comedic incompetence.
