STARMYU 3

"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.

The story starts when Yuuta Hoshiya enters Ayana Academy, a school focusing on show business activities, specifically music. The academy has a group of the three students with the highest grades in the musical department, and they are known as the Kao Kai (Cherry Blossom Flower Association). This organization stands at the top of the pecking order within the academy. The shortcut to entering the musical department is to enter the Star Frame class, which is directly taught by the members, and to be recognized by them. Unfortunately, due to their own problems, students Tōru, Kaito, Shou, Shuu, and Yuuta are all struggling to even remain candidates for the musical department. By a stroke of luck, however, the five are spotted by Kao Kai member Ootori, and they pique his interest.

A new year arrives as the school festival ends. The season has come as Kaou-kai members leave their jobs at the Kaou building. Each musical team prepares for the final stage, Graduation Ceremony, to show their thankfulness. After the incident at the school festival, the now-disbanded Team Ootori is disqualified from participating. In the midst of these events, Yuuta Hoshitani and the others make a decision…

As the two meet after school, they bond through songs and begin to harmonize as their hearts beat together. It starts out slowly but soon their feelings for one another grow and suddenly they both realize that they are in love. Kusakabe's emotions are frivolous, pure and direct causing Sajou to hesitate at first, but he gradually opens his heart. The boys learn about each other, as well as themselves, as they support one another during this difficult time in their youth. As the time to start thinking about their futures approaches, what do these young men find as they try to move forward...
