Picking up after the intraschool music competition at Seiso Academy, this two-episode special continues the story of Kahoko, a music student still finding her footing. Three new people enter her world: Eto, a boy with a blunt, abrasive manner; Akihiko Kira, the school board's new and youthful director; and Aoi Kaji, an enigmatic student who has just transferred in. The franchise began as a game and an earlier anime series.
