Shortly after the Japanese airing of Episode Three of the UniteUp! anime, the official accounts for the series revealed that it will be going on hiatus starting with the next episode. According to the official website, this delay on the fourth episode and beyond is due to COVID-19 affecting the production schedule. As of this writing, the series will air two special episodes on January 28, 2023 and February 4, 2023, and Episode Four is scheduled to air on February 11, 2023.
The anime’s story centers on Akira Kiyose, who sings on a video streaming site under the singer name “KIKUNOYU.” One day the talent agency sMiLea Production scouts him. sMiLea is an agency founded by the retired legendary idol pair AneLa to train new budding idols. Akira then forms an idol group with Banri Naoe and Chihiro Isuzugawa, who were also scouted. Their new group, Protostar, will have their debut alongside other new idol groups with sMiLea Production: Legit and Jaxx Jaxx.
