Kouhei Makino is the manager of the idols at Hoshimi Production and is the same age as [Mana Nagase](https://anilist.co/character/164062/). He is a good-natured person who doesn't know when to say no. He doesn't have any particular skills, but he supports the idols with honest work.

He went to high school with Mana Nagase and was close friends with her.

After a successful audition, high school student Kotono Nagase and her best friend move into a dorm with eight other aspiring idols. They quickly realize it takes more than cute choreography and cute outfits to reach the top—it will take blood, sweat, and tears to advance in the idol-ranking VENUS program, where the top spot is held by superstar Mana Nagase…who happens to be Kotono’s older sister.
