On the cusp of fame, rock band the JoKers mysteriously splits up. One year later, vocalist Jyo Kodukai has débuted in the U.S. while guitarist Jyo Kaieda is a miserable, entitled, handsome university student with only a purple sports car to show for his former glory days.
To reignite Jyo Kaieda’s musical passion, former JoKers members and their eccentric café owner friend hatch a plan – get Jyo Kaieda to mentor the new, all-girl high-schooler rock band, Drop Doll!
Despite his strict standards, the out-of-synch rookies easily find the passion for rock that Jyo Kaieda has lost. While begrudgingly following his coaching, feisty Drop Doll drummer Sakura isn’t falling for his pretty-boy charm and grows more and more determined to prove her worth as a musician. As they master their sound, bandmates Sakura, Mao and Rina start to love playing together – and their passion for rock is simply infectious!
‘JK’ in the title refers to joshi kōsei, meaning high school girls.
