Rock Is a Lady's Modesty, Vol. 1

When her mother marries into high society, Lilisa Suzunomiya is forced to leave her commoner ways behind. Now enrolled at an elite all-girls academy, she's expected to smile politely, sip tea, and hang up her beloved guitar for (ugh…) a violin. But when she hears drums echoing from the old school building, Lilisa is dragged into a jam session with the secretly rebellious young lady Otoha Kurogane, and her passion for music is reignited! High society better watch out—the academy's most demure maidens are teaming up to form an elegant rock band the likes of which the world has never seen!

Volume 1 of the Rock Is a Lady's Modesty manga series by Hiroshi Fukuda.
