Ai Ore (Manga) Vol 01

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! Viz Media Llc
