THE RIBBON HERO Reveals Final Trailer and More Cast Ahead of Next Week’s Global Premiere

THE RIBBON HERO, the new film based on Osamu Tezuka’s Ribbon no Kishi (Princess Knight) has revealed its final trailer and more voice cast. This is the franchise’s first anime project in 27 years, and it will premiere globally exclusively on Netflix on August 8, 2026.

The original Ribbon no Kishi manga debuted in 1953 and follows Sapphire, a princess born with both a boy’s and a girl’s heart, who takes on the role of a masked hero. The series later received a TV anime adaptation in 1967-1968, with the most recent animated project being a short film shown in 1999. The official synopsis:

Sapphire is the princess of a kingdom that no longer exists. Having lost everything in her homeland of Silverland to the calamity known as “Nergal,” she wanders in despair until she finally arrives in Goldland.

Though burdened by her past, she begins to find a glimmer of hope as she encounters the kindness of the people there. But as if to sneer at her peaceful new life, the calamity Nergal appears once more. The very despair that once reduced her homeland to ashes now threatens to steal the light from this land as well.

“I won’t lose anything ever again. And I won’t let anyone else lose anything either.” Brushing away her tears of sorrow, the girl takes up her sword. This is the story of a lone hero who ties her ribbon and resolves to defy her fate.

Saya (Lalande) voices the main character Sapphire, while the full voice cast includes:
