In order to get Pure Palette's name more well-known, Aine and Mio are to appear on the TV program "Genius Battle Selection". However, Karen Kamishiro reigns as the absolute queen of geniuses on the show. Admiring and aiming to surpass them, Mio comes to face Love Me Tear, and learns the essentials of Aikatsu! from Karen.

Four months have passed since Aine has begun her Aikatsu! However, in comparison to Mio, her reputation and skills aren't quite there yet. Under Mio's instruction, she even uploads "'tried to do' videos" onto AiTube, but the number of views don't increase much. Mio, assessing the situation, seems to have become aware of Aine's greatest talent?
