The anime features an ensemble voice cast for several male idol units in the series, with the actors for the Protostar unit consisting of Kikunosuke Toya as Akira Kiyose, Ryotaro Yamaguchi as Banri Naoe, and Amon Hirai as Chihiro Isuzugawa.
UniteUp! is part of the male idol multimedia project by Sony Music Entertainment Japan, which was described as a “next dimensional idol project” that was initially launched in December 2021. An anime series was announced at Aniplex Online Fest 2022.


Crunchyroll is currently streaming the anime, describing the synopsis as:
“I’m going to be an idol…?” Akira Kiyose is a high school student who loves to sing. His songs were published to a video sharing site as the internet singer “KIKUNOYU”. One day, he is scouted by the entertainment agency “sMiLea Production” after they hear his singing voice. The agency was established to nurture up-and-coming idols by the legendary idol duo “Anela” after they suddenly retired. Akira forms a group with Banri Naoe and Chihiro Isuzugawa, who were also scouted. The three online singers are inspired by the idols “LEGIT” and “JAXX/JAXX”, also belonging to the same agency, and aim to make their idol debut with their own thoughts and feelings in mind…!
