"I don't know how to give up on my dreams…" Yuuta Hoshitani, who enrolled in the prestigious Ayanagi Academy for music entertainment, passed the first-year test to become a musical department student in his second year. However, the new school year immediately presents new trials for the returning students. The first task on the second-year curriculum is supporting the graduation stage performance of Ootori and the other graduating Kaou Council members. There are five roles known as "second-year training roles" in the legendary musical Shadow & Lights. Every year, a team of only five second-year students get to step on stage as performers in the musical. It is a great honor for the musical department students, to co-star with their respected former leaders. To earn a ticket to glory, Hoshitani and 24 other new musical department students take on the training auditions. At that moment, the coming-of-age slapstick musical story raises the curtains once more.
