On the first day of the intensive course, Haruka met Ichijuki Otoya (voiced by Takuma Terashima) and Seikawa Mato (voiced by Kenichi Suzumura) again. They all lived in the same dormitory for newcomers, and a new life was about to begin. What kind of sparks will Haruka, who aspires to become a composer, create with them? What kind of performance will ST☆RISH have in the debut Live, which was later called the legend? Such a group of dazzling youth idols began to move forward towards their dreams.
