The protagonist of the tale is Hinano, a mild-mannered and quite typical 17-year-old girl. Hinano had liked visiting the planetarium her grandmother ran since she was a tiny child, but one day she learned that the planetarium would be closed. Hinano was concerned about what she could do to help her grandma and the planetarium until, by chance, she happens to see a woman dancing on a pole under a starry sky one day. She collects her pals, and the group erects a stage for performances in the planetarium. They then dive into the world of pole dancing.
