A childhood promise to discover an asteroid brings a girl into a school club where stargazing and geology have been merged under one roof.
Mira plans to join the astronomy club, only to find an Earth Sciences Club shared with geology enthusiasts. Her reunion with Ao turns an old wish into a project that can be pursued with other people, through observation, field trips and the slow acquisition of practical knowledge.
The merger makes the club more than a convenient home for one promise. Stars and rocks ask for different tools and kinds of attention, yet both reward people who look carefully and compare what they find. Mira's wish supplies a direction without exhausting the interests of the others around her. The observatory artwork establishes a shared night sky; the accompanying group frame keeps learning in the company of people rather than treating discovery as a solitary flash of talent. Begin with the twelve numbered television episodes. The recap and small promotional animations do not add another season to that commitment.
