Netflix revealed the first full trailer for The Ribbon Hero, a new adaptation inspired by the classic Princess Knight, created by Osamu Tezuka.
The film premieres worldwide on August 8, 2026.

The anime is being produced by studio OUTLINE, founded by the film's director himself. The project also features character designs by Kei Mochizuki, visual collaboration by Mai Yoneyama, and animation adaptation by Issei Arakaki.
The story follows Sapphire, a princess born with two hearts—one male and one female. Since the kingdom only allows male heirs, she is raised as a prince and must hide her true identity to protect the throne.
