Chapter 1: Stars in the Sky

Sora and her twin brother Subaru decide to pursue a life as an idol duet by enrolling in Saotome Academy - with the hope of getting a national debut. While there, they make friendships with the boys who will one day make up STARISH, as well as the shy composer Nanami. While they work hard to make their dreams come true; only one group can debut, but for Sora, losing is unthinkable - and would result in going back to being a bed-ridden hospital patient.
