The narrative focuses on Hinano, a remarkably ordinary and gentle 17-year-old girl. Her grandmother had operated a planetarium that Hinano adored since early childhood, but Hinano eventually learned that the facility would be shutting down. Concerned about what she might do to help her grandmother and the planetarium, Hinano happened to spot a woman pole dancing beneath a starry sky one day. She rallied her friends, and they collectively arranged a stage within the planetarium to put on performances, thereby entering the realm of pole dancing.
