It's a 30 minute-length opera film, in which you will see no human being acting. It's VOCALOID that provides all the songs for the play. VOCALOID is a technology of singing voice synthesis and the name of application software based on that technology. And all the actresses in the play are Bunraku puppets. Bunraku is one of Japan's traditional performing arts with 300 years of history. The trinity of lifelike puppet play, songs from VOCALOID and techno music using Japanese traditional musical instruments illustrates the complexity of human deep psyche.
