UniteUp!: Uni:Birth

After PROTOSTAR’s CD debut and their victory at the Rookie Men’s Idol Fes, Akira, Banri, and Chihiro begin to settle into life as rising idols at sMiLea Production. Their progress brings new attention, but also higher expectations as they continue building their place in the music world.

When the agency sets up a release battle between PROTOSTAR, LEGIT, and JAXX/JAXX, the young idols must face competition from the very groups they usually stand beside. The season follows their daily efforts, rivalries, and teamwork as each group searches for its own sound and stage presence.
