Romi crashes into the real world chasing monsters that literally embody what people feel, and suddenly catching them isn't about victory, it's about understanding why someone is angry, jealous, or heartbroken in the first place. The show treats emotions like they're real enough to hunt, real enough to hurt people, real enough to matter. That's the hook: a magical girl story where the actual villain is loneliness, and the only way to win is to look someone in the eye and recognize what they're going through.

Romi is a princess of the Emotion Kingdom, a fantasy realm. By accident she releases the Teeniepings, mind fairies that were locked away for ages and can sway how people feel and act. Once loose on Earth, the playful creatures slip into people's minds and cause trouble in their lives. Romi has to go to the human world and catch every one of them before they throw it into chaos. There she lives as an ordinary girl and transforms into a magical girl to stop them. Meanwhile she works at the Bakery Heartrose alongside her coworkers Ian, Kyle and Jun. Expect a short-form magical girl adventure with fantasy and drama.
