Kawagoe Boys Sing

It has been a month since genius orchestra conductor Haruo Hibiki was unceremoniously dismissed from his position at the Cosmopolitan Philharmonic Orchestra. Unable to find a similar position, the eccentric Haruo gets roped into teaching music at Kawagoe Private Academy instead. It is here that he receives an ultimatum: if he can put together a boys' choir at the school and win the annual competition, he can return to his former job.

Desperate to return to the limelight, Haruo searches the entire school for suitable voices for the choir. Unfortunately, his inability to communicate normally puts him at odds with almost everyone he encounters—including Tenshi Dei, a boy who loves to sing but cannot do so in front of others. With only a year to complete this lofty goal, Haruo will need to learn how to get along with the boys he can manage to recruit while also supporting their growth into a formidable choir.
