Netflix has recently unveiled its latest original anime film, The Ribbon Hero, which serves as a contemporary reimagining of Osamu Tezuka’s 1950s manga Princess Knight. The first promotional poster, featuring a female character (presumably the lead, Sapphire), was crafted by Fate/Grand Order artist Kei Mochizuki alongside Mai Yoneyama, who worked on Cyberpunk: Edgerunners. While intended to build excitement, some anime enthusiasts in Japan are expressing concern that the adaptation appears markedly (even “entirely”) different from the original work.
Despite some viewers placing their confidence in director Yuki Igarashi—known for his work on Mob Psycho 100, Frieren: Beyond Journey’s End, and Star Wars: Visions—many are still doubtful about the artistic direction. The new style has sparked debate among the fan community.
Some speculate that the inclusion of the “Princess Knight” title was a strategic move to draw attention, implying that The Ribbon Hero might struggle to gain traction as a standalone creation without leveraging its heritage. Others would have preferred if Outline and Twin Engine, the studios behind the project, opted for an original intellectual property if the character designs deviate so significantly from their roots.

Although the Ribbon Hero character depicted in the poster (assumed to be Sapphire) isn’t aesthetically displeasing, her more angular and mature appearance bears little resemblance to the softer, rounded features characteristic of Tezuka’s original manga and anime renditions of Sapphire.
The Ribbon Hero is positioned as a “modern interpretation” of Princess Knight, a choice evident in its visual style and character aesthetics. While this approach may appeal to contemporary viewers, long-time fans of Princess Knight are feeling alienated by the alterations. Some have lost enthusiasm for the film, while others have likened the character design to “tasteless gum.”
The Ribbon Hero is scheduled to debut on Netflix in August 2026.
