The manga is based on THE iDOLM@STER, a music-oriented game franchise in which the player guides 13 idol singers as their producer.
The spinoff manga centers on the character Kotori Otonashi, an office clerk at 765 Production, during her high school days.
The story follows the new third-year students who are aiming for the vacated top spot at Suzuran High School, and the newcomers who appear in their midst: the third-year transfer student Kazeo Kaburagi and the new first-year student Ryōhei Kagami.
