リボンの騎士
At various times in his career, Tezuka worked on short original animation films, or "theater anime", which included some of the "Princess Knight" story. Samples of this work were shown in the "300 Inch Theater", which was held at Tezuka Osamu World in the Kyoto Station Building from July 1999. In this film, the Phoenix (from the eponymous Tezuka manga) plays the role of storyteller, and introduces two pictures. The first part tells the story of "Princess Knight", and the second part talks about Minamoto Yoshitsune, who made his mark in the history of Kyoto as a person who became entangled in a struggle by another's wicked design in spite of his desire for peace just like Sapphire.
