The iDOLM@STER Shiny Colors (2023)

There is a lot of excitement among the newly formed idol groups on the 283 Productions label: the newcomer idol competition W.I.N.G. starts in a few months, and many young, talented female artists fancy their chances of winning the coveted title. Both the already-established girls from L’Antica, who want to tell exciting stories with their songs and the three-piece group Alstroemeria, who are currently still trying to figure out what they want to achieve as idols, are planning to take part in the competition, as are the Houkago Climax Girls, who have so far mainly made a name for themselves in the local shopping centre.

The two newly recruited idols, Hiori Kazano and Meguru Hachimiya, would also like to try their luck, but their producer thinks their unit still lacks that certain something. But then, one evening, he sees Mano Sakuragi sitting alone on a bench in the park, singing a beautiful song. He tries to convince the shy girl to become an idol, too, and supports the two other girls on stage. Thus, the idol group Illumination STARS is born, and the competition for first place begins.
