The Most Beautiful Singing Voice in the World

A companion piece to The Castle of Murder, adapted from the first edition of the Grimms' Fairy Tales story of the same name. This children's opera script was written for the 2012 International Children's Day on June 1. It features many songs and takes the style of a musical film rather than a stage opera. Children who receive gifts for Children's Day turn into beasts. The only way to save them is to collect the most beautiful voices in the world, so the characters from The Adaptation of The Castle of Murder set off on an adventure. The whole work is lighthearted and humorous. The "No. 1" in parentheses in the work refers to the author.
