The app is a virtual idol girl group simulation game with 3D characters, which can be enjoyed by both children and adults. After selecting your favorite virtual girl idol, you can make your own group, sing and dance with them, and play a variety of mini games.

It also has a special "Story Mode", which tells the story of each girl, including the backgrounds of the parents and the reason why the girl joined the group.

Aside from that, you can also play "Battle Mode" to fight against other groups for the top position, or "Challenge Mode" to complete various challenges.
