THE END is an opera born from the collaboration between Keiichirou Shibuya, director and screenwriter Toshiki Okada, and illustrator YKBX. This production features no humans; instead of the familiar elements of non-existent singers and orchestras, it presents arias and recitatives by Hatsune Miku and Vocaloid, with a story conveyed through computer-generated music and visuals. This production experiments with the traditional tragic structure of opera, which asks "What is death?" and "What is an end?", by positioning Hatsune Miku as a mediator to reinterpret it in a modern context.
