Kuno and Kodachi come across the ancient tsuzumi (drum) and biwa (lute), respectively, both having devastating destructive power when played. Kuno showcases the weaponry of his drum, destroying much of the school and putting Principal Kuno in depression. Kodachi later offers Principal Kuno her biwa, allowing him to avenge his shattered ukulele. (Source: Wikipedia)
