A 25-year-old office worker endures impossible tasks from everyone around her, swallows every complaint, then walks into a karaoke booth and screams death metal until her lungs burn. The gap between her perfectly polite exterior and what she actually feels is the entire joke, and it never gets old. Every episode is five minutes of recognition so precise it hurts, followed by the one moment she gets to be completely, violently honest.

Retsuko is a twenty-five-year-old red panda working in the accounting department of her dream company. On the surface, she's the perfect employee: diligent, modest, and never one to talk back. But beneath that polite exterior, her irritation keeps building. Her boss makes sexist remarks and hands her impossible tasks. Her condescending coworkers take advantage of her small stature and meekness. She keeps quiet in a workplace ruled by rank and appearances. So when the frustration hits its limit, Retsuko heads to karaoke alone and belts out death metal that rips into the foolishness and hypocrisy around her. This is her release, the place where the quiet clerk finally lets loose. It's equal parts workplace comedy and primal scream therapy.
