Rock is a Lady's Modesty

Following her mother's marriage into high society, Lilisa Suzunomiya is compelled to leave her commoner life behind. Now enrolled at an elite all-girls academy, she is expected to carry herself with flawless grace—smiling politely, taking tea, and setting aside her beloved guitar in favor of, much to her dismay, a violin. But when the sound of drums echoes from the old school building, Lilisa finds herself pulled into a jam session with Otoha Kurogane, a young lady who hides a rebellious streak beneath her impeccable manners, and her passion for music is rekindled. High society had better take notice: the academy's most demure young ladies are joining forces to form an elegant rock band unlike anything the world has ever seen!
