Yûki Igarashi’s “Princess Knight” Film: A Conservative Reworking of Tezuka’s Manga

The animated feature follows Sapphire, a princess forced into exile after the monstrous Nergal destroys her kingdom of Silverland. Accompanied by her lady-in-waiting Zirco, she seeks refuge in Goldland and takes a mining job to earn money for crystal supplies that appease the Nergal. When another attack drives her into a crystal pool, her head ribbon activates, transforming her into Princess Knight—a heroine capable of defeating interdimensional foes. Local noble Velvet monitors the conflict, hoping to free his own lands from the Nergal’s grip.

Directed by first-time filmmaker Yûki Igarashi, the movie represents the first major cinematic adaptation of Osamu Tezuka’s post-war manga *Princess Knight* in decades. The original series was celebrated for its gender-flipping premise, positioning the heroine as a pioneering figure in early manga history.

The Guardian’s review argues that the adaptation narrows the source material’s scope, concentrating almost exclusively on Sapphire’s “girlishly feminine” side and abandoning the pioneering gender-fluid narrative that defined the manga. The critic describes the story as a “saccharine do-gooder” that repeatedly emphasizes altruism without offering fresh terrain for the character. Battle sequences are portrayed as conventional, lacking the inventive spectacle found in series such as *One Piece* or *My Hero Academia*. Consequently, the film is characterized as a run-of-the-mill “girl-power puff” rather than a bold reinterpretation.

Despite narrative shortcomings, the animation receives praise for its stylistic variety. The film blends “haute Euro-pageantry” with striking 2D backdrops, incorporates chibi-style emotional moments, and employs shadow-play interludes during action set-pieces. This visual inventiveness is noted as a rare strength in contemporary anime productions.

The Guardian

While the movie showcases impressive artistic ambition, the review concludes that its conservative storytelling and reliance on familiar tropes limit its impact, leaving it largely a conventional entry in the genre rather than a transformative homage to Tezuka’s groundbreaking work.
