Kawagoe Boys Sing

Kawagoe Academy's Tenshi lives a peaceful daily life until Haruo Hibiki, a former orchestra conductor, appears on the scene. Haruo, known for his troublesome personality, is given a chance to rejoin the orchestra if he establishes a boy's choir club with male voices and wins the National Boys' Choir Competition. Tenshi and his friends are forced to join the choir club, initially struggling with Haruo's immaturity and abrasive behavior. As they continue to sing under Haruo's guidance, they become absorbed in the choir, preparing for the competition against rival teams.
