Netflix recently announced production of The Ribbon Hero, a modern anime film adaptation of Osamu Tezuka’s classic manga Princess Knight (Ribbon no Kishi). The worldwide release is scheduled for .
The first promotional image sparked strong criticism. Japanese audiences reacted negatively to the radical departure from Tezuka’s original art style.
It looks like flavorless gum.
The protagonist Sapphire appears with sharp, mature featuresβa stark contrast to the soft, rounded lines that defined the 1950s manga. Many commenters described the new look as completely different from the source material.

Creative Team and Vision
- Director: Yuki Igarashi (feature film debut at Outline studio)
- Character Designer: Kei Mochizuki (known for Fate/Grand Order)
The team defends their approach as a way to introduce Tezuka’s themes to contemporary audiences. Igarashi states the project is made with deep respect for both the author and the Takarazuka Revue, the iconic theater company that originally inspired the mangaka.
A Foundational Legacy
Princess Knight is considered one of the pioneering works of the shoujo genre. The story follows Princess Sapphire, born with both a male and female heart due to a celestial mistake, forcing her to live as a prince while secretly embracing her true identity.
This film marks the first animated version in 27 yearsβnearly three decades of anticipation.
Fan Concerns and Divided Reactions
A significant portion of the audience suspects a tactical bait-and-switch:
- The Princess Knight label may have been added to guarantee attention
- Many would prefer a new franchise rather than an adaptation that discards Tezuka’s visual identity
- Some question whether the legacy brand is merely a veneer for a different product
Others place trust in Igarashi’s technical record, hoping quality will compensate for the aesthetic shift.
The Core Question
As production continues, a delicate balance remains: Can this reinvention honor a historic legacy while meeting modern visual demands? Fans will have to wait for the actual animation to see if the storytelling wins them backβor if the visual departure proves too great a distance to bridge.
