The boy (who looks like a girl) meets girl (who looks like a boy) romance!

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!

When the lead singer of Blaue Rosen announces she is moving overseas, Akira does all he can to convince Mizuki and her bandmates to let him join. But will a resistant Mizuki allow him into her band, much less her heart?
