Mizuki is the female "prince" of her all-girls school and the lead guitarist in an all-girl rock band. Akira is the male "princess" of his all-boys school and wants to join her band. Love may be on his mind, but romance is difficult when everyone keeps mistaking Mizuki for a boy and Akira for a girl!

The members of Blaue Rosen and Akira's schoolmates have found themselves at the same beachside resort for summer vacation. Akira wants some alone time with Mizuki, but will he ever be able to shake off Ran and Rui?
