Shu’s had a rough start to life, and doesn’t think he has much of a future—until fate brings him together with talented young pianist and fellow student Akari Yuzuki, the “left-handed angel,” for one high-flying adventure. But when tragedy cuts their relationship short, Shu realizes he must find a way to live for them both…and realizes that something is no longer quite right with his own left hand…
It's only been a short time since tragedy struck and genius pianist Akari Yuzuki passed away…but unknown to most, she lives on as the left hand of rough voiced and rough mannered delinquent, Shusuke Matoba! In an attempt to save Akari's best friend Neri Kuon, he frantically practices the piano, and though he only first touched the keys a month ago, thanks to instruction from Akari's father Mikage and his own natural ear, he's finally ready to surprise her at a piano competition! But can his awkward melody—and Akari's gentle accompaniment—save Kuon from despair?
