College Cosmos

College Cosmos (カレッジ・コスモス) is an idol group made up of female university students which was formed in October 2018 as a joint project between Space Craft Group and.

The group was formed in search of a new type of idol to replace the present image of "idol (アイドル) = guuzou (偶像)" —guuzou being the Japanese word for "idol" which has the connotation of religious or cult-like worship. Therefore College Cosmos will not have the unspoken "love ban" rule. The members will balance work and their studies with the aim of becoming known as an intellectual group of idols.
