Kawagoe Boys Sing (Original Japanese Version)

The choir heads into the mountains for a singing training camp, but when they arrive, they discover that the site they'd reserved is already being used by a rival school! Meanwhile, Haruo refuses to do anything but...look for kabocha squash?

The choir is still reeling from the loss of a member, but they're determined to practice as hard as they can for the upcoming competition. Unfortunately, their parents aren't happy about the choir's late hours and they complain to the school!
