Chika is an underground idol who lacks the voice, rhythm, and stage presence necessary to succeed in the competitive music industry. Despite her constant failures and clumsy performances, she has one dedicated supporter who remains the only person in the world cheering for her.

In the crowded world of local idols, Chika stands out for all the wrong reasons. Her performances are notoriously off-key and her dancing is perpetually out of sync, leaving her at the very bottom of the industry rankings. While other aspiring stars climb the ladder of fame, Chika struggles to justify her presence on stage in front of mostly empty venues.

The story focuses on the unique bond between this struggling performer and the solitary individual who sees something special in her lack of grace. This devoted fan attends every show and buys every piece of merchandise, providing the unwavering encouragement Chika needs to keep going. Their poignant relationship creates a touching narrative about finding personal worth and the power of singular devotion.

Follow the journey of Chika, an untalented underground idol, and the dedicated supporter who remains her only fan in this complete manga.
