Goodbye, Don Glees!

Two boys named Rōma and Toto meet when Rōma moves from Tokyo to the countryside, which he cannot grow accustomed to. But when he meets Toto, they become a duo, naming themselves "Don Glees." Eventually, Toto was supposed to move out to Tokyo for school, but on the summer of their first year of high school, they meet Drop, a new addition to Don Glees, who invites them to "view the world from above." When Rōma and Toto follow Drop, they become involved in a forest fire that gets blamed on them, and go off in search of a missing drone that has evidence of their innocence. A small incident becomes an important, life-changing journey.
