If “Mugen Train” was the spark, “Infinity Castle” is the inferno. The latest “Demon Slayer” movie drops their mix of both comedic and action-packed storytelling for all-out chaos, a roaring, beautifully animated final war between the Demon Slayer Corps and the Demon King.
The “Demon Slayer” series, which originally started in 2016 as a manga, or Japanese comic, has been made into four seasons and two movies, with two more to follow. The story follows Tanjiro Kamado, a young boy who becomes a demon slayer after a demon attacks his family, killing them all except for his sister Nezuko, who is turned into a demon herself. To avenge his family and find a cure for Nezuko, Tanjiro joins the Demon Slayer Corps, where he learns to fight demons using specialized techniques called Breathing Techniques, where they utilize specific forces of nature to fight against and kill the demons.
Demons are immortal, malevolent creatures who were once human and survive off consuming human blood. Every demon was once a human, and turned into one by consuming another demon’s blood. They possess enhanced physical abilities like strength and regeneration, but are vulnerable to sunlight, and beheading by swords, and wisteria flowers.
The film begins mid-freefall, literally and emotionally. The Hashira, the leaders of the Slayer Corps, Tanjiro and his friends are pulled into Muzan’s twisted domain, an endless labyrinth that bends space like a nightmare. Walls are constantly shifting, staircases are flipping and the floor becomes walls and ceilings.
Each Hashira faces their battle against the Upper Moons, who are the six strongest demons in the series. Ufotable’s animation hits harder than ever. Flames flare like real fire, and even the quiet moments feel sharp with tension. But what really makes Infinity Castle special isn’t the action, but rather the resolve behind it. At the beginning, Tanjiro is fighting for revenge, to find a cure for his sister. But now, he’s fighting for the world his sister deserves. Every character bleeds for something personal. Mitsuri fights to protect love, Obanai for redemption, Giyu for duty.
And surprisingly for such a bloody and violent part of the series, the emotional parts of the story are well written, and in fact, take up a large portion of the movie. This sometimes is overdone, as they are usually put right in the climax of battles, and can sometimes break away from the immersion of the battles.
The Infinity Castle, the setting of the movie, is breathtaking: it’s a kaleidoscope of shifting architecture and impossible geometry, and the CGI blends well with the 2D animation of the movie. The score by Yuki Kajiura and Go Shiina pushes everything higher, blending traditional Japanese instruments with cinematic intensity. And even though it’s the first out of a three movie trilogy, it already feels like an ending starting to take shape. It’s a brutal, stunning reminder of what Demon Slayer has always been about: protecting humanity that is already near its end.
