Venus Project (HASEGAWA Kouji)

From [MangaHelpers](https://www.mangaupdates.com/groups.html?id=1011): This manga is based on the idol-training battle game (which has also become an anime) of the same name. In the near future, a new form of entertainment called "Formula Venus (FV)" becomes popular. On FV, top idols battle it out in live performances using their strength, skills, and experience. This story begins with a fledgling idol named Takano Karen, who wants to become the top of FV! [tethysdust]
