Youmenosay

 (ゆめのせい) is a three-member Japanese female idol group formed on March 26, 2022.

They made their stage debut on May 7, 2022 @Shibuya DIVE.

The group's concept is to become "real 2-dimensional idols" and aim to create a "non-fiction anime" based on their real idol activities.

They plan to produce a manga based on them, design characters, and release character voices. They will also produce other 2D-inspired activities in parallel with their idol activities.
