St. Elmo's Fire and Tears of Andromeda form a two-volume story set in the astronomy club at Kugano High School. The first follows Anzai Elmo as she returns to her hometown and joins the club after being moved by its night sky; the second follows the club's planetarium project and the students' growth as they face questions about their futures.

A two-volume coming-of-age story in which high-school students, drawn together by the stars, consider where they belong and what lies ahead.
