As preparations begin for Seishou Music Academy's yearly Seishou Festival, the girls of the 99th class are gearing up to perform their very own rendition of Starlight, the tragic tale of two goddesses drawn together by the glow of the heavens but destined to be pulled apart, never to meet again. Created to foster the next generation of theatrical talent, this girls' only school works to improve the singing, acting, and dancing skills of its students.
