Demon Slayer: Infinity Castle interview: Inside the the creative process and stunning success of 2025’s biggest anime

Ufotable is renowned as one of the best contemporary anime studios in the world, producing such works as Fate/Zero and the Fate/stay night: Heaven’s Feel film trilogy. The Tokyo-based studio is also known for its seamless fusion of hand-drawn 2D and 3D animation, elevating CG in a medium that traditionally looks down on its use. While visiting the United States for the Golden Globes (they were nominated for Best Animated Feature but lost to Kpop Demon Hunters), Ufotable co-founder and Infinity Castle writer/chief director Hikaru Kondo, along with producer Yuma Takahashi, spoke with Polygon via translator about the film’s box office success and their approach to adapting the manga arc into a trilogy of films.
