Yuyu, a first-year high school student, becomes completely fascinated by the ouendan, a Japanese cheering squad, and decides to join the team. She ends up in the same group as a classmate who, for some reason, is always in a bad mood. The story is set in a high school where the ouendan serves as a central activity, with the narrative following Yuyu’s efforts to be part of this spirited world while navigating her tense relationship with her perpetually grumpy peer. The manga began serialization in February 2025 and concluded with three volumes.
