## Ufotable Details How they Brought *Demon Slayer: Infinity Castle’s* Epic Fights to Life
As io9 has thoroughly glazed in detail, 2025 was a definitive year for anime films, thanks in part to the meteoric box-office success of *Demon Slayer: Infinity Castle*. As the film prepares for award season, its directors shared some behind-the-scenes tidbits about how studio Ufotable pushed past their limits (and the laws of physics) to bring the megapopular anime’s bombastic fights to life.
Speaking with Entertainment Weekly, *Infinity Castle* director Haruo Sotozaki, director of photography Yuichi Terao, and Ufotable president Hikaru Kondo reminisced about how the studio’s commitment to making the best anime possible contributed to the film being at the table this award season.
In the movie, hero Tanjiro Kamado and the rest of the Demon Slayer Corps dive straight into enemy territory, battling an onslaught of powerful enemies and overpowered bosses in the ever-shifting maze that is the Infinity Castle. While this isn’t *demon Slayer’s* first rodeo in cinemas, *Infinity Castle* marks the beginning of the end of the banner series as the first of a film trilogy. having the first leg of that trilogy play in IMAX theaters inspired Ufotable to elevate the streamer anime into a cinematic experience. The studio wanted to ensure that every corner of the screen was popping with detail, which required collaboration in its compositing of 2D characters moving through 3D environments in its fluid action sequences.”If you look at a lot of the keyframes, the key animation, the sakuga in this film, we worked really closely with our 3D department to make sure everyone’s in full lockstep because we didn’t want any weird bizarre effects where perhaps these 2D characters are sliding around on the 3D surroundings and environments,” Sotozaki told EW. “So it was very important that the 2D keyframe animators were talking to our 3D team to make sure the compositions were perfect.”

To prevent oopsies during production, he said ufotable would frequently enough test keyframes in their respective 3D environments before finishing key animations. While hero Tanjiro’s secret to success is his impeccable breathing techniques, Terao explained that Ufotable’s animators would hype themselves up with music so that, once pencil hit paper, *Infinity Castle’s* many set pieces and sequencing momentum would pour straight into its animation.
