The reason why lovelive was expelled from the second dimension: because lovelive's nine virtual characters have the bonus of three-dimensional idols, they become nine real seiyuu singers and enter the third dimension. So lovelive no longer belongs to the second dimension and was expelled from the second dimension.

LoveLive！ LoveLive！ The school idol project is a mixed media campus idol project jointly launched by Japanese animation company Risheng, record company Landis and ACG monthly magazine "Get an Electric Shock G" on 20 10 * * *.

Planning includes music works, TV and radio programs, textbooks, cartoon illustrations, animation, games, environment, etc. The slogan of the work is the story of everyone realizing their dreams together.

Lovely plot:

National Yinnai Muban College, a traditional women's high school with a long history in Chiyoda-ku, Tokyo, is facing the crisis of abolishing the school because of the sharp drop in enrollment. One of the students, a young girl, came up with a brilliant idea, that is, to become an idol of the college.

As long as Yinnai Muban's idol image is successfully established, the school's popularity will increase and the enrollment situation will improve. In this way, with the girl's active persuasion, eight other girls with distinct personalities decided to help her become an idol together, hoping to save her favorite campus and realize her dreams with the help of the idol's fame.
