After the ending of the last Demon Slayer season, I had no idea what was going to be awaiting Tanjiro and the Demon Slayer Corps in the Infinity Castle. I also did NOT want to know what would happen because I just knew it was not going to be good for my mental health. Of course, as the masochist fan I am, I had to carry on and go forth.
Demon Slayer: Kimetsu no Yaiba Infinity Castle picks up right where we last left off. Tanjiro, Zenitsu, Inosuke, and the Hashira are falling into Muzan’s maze. At last, the ball is in Muzan’s court, and he has the advantage in this infinite night. Hiding in this endless playground, he has upper-rank demons waiting for their chance to prove their undying loyalty.
I’ve attended every single Demon Slayer theatrical event, from the Mugen Train movie to the special premieres of the Swordsmith and Hashira Training arcs. While many criticize the decision to animate the ending of the story as a movie instead of the traditional episodic anime format, I fully support the movie decision. It’s undeniable that Demon Slayer is made for the big screen, and Infinity Castle only furthers the case.
Not a minute of the over two-hour run time is wasted visually. From the high-intensity fights to the slow and emotional scenes, the animation is consistently stunning. Add to that the incredible score overlaying every moment so carefully. At times, it felt like the music was coming from my heart; it felt so perfectly suited.
The movie does not stray from Demon Slayer’s typical storytelling style, juxtaposing high-action moments with slower-paced, emotional flashbacks. While a newbie may be thrown off by this, the fandom already knows this is what to be expected. It is not Demon Slayer without these important perspectives.
Each member of the Demon Slayer Corps has a story on why this final battle is so important. At the same time, each Upper Rank demon has a mirroring story of their path to losing their humanity. These stories are a necessity in Demon Slayer and are especially crucial in Infinity Castle. They serve to up the ante and further prove this story is so much more complicated than good vs evil. (More on this in a later, spoiler-filled review to come.)
If there is something else that Demon Slayer Infinity Castle proves, it is that the English dubbing performances are insane and worthy of awards. The English cast has always been fantastic, but Infinity Castle lets two actors voicing supporting characters, demons at that, steal the spotlight. And managing that after announcing Channing Tatum is no easy feat.
First, we have Alejandro Saab as Kaigaku, a demon who faces off with Zenitsu. His performance alongside Aleks Le as Zenitsu had me awestruck; I almost switched who I was rooting for. The way he perfectly captured a cocky demon, too consumed with pain to see his failures, was mesmerizing. Saab brings out a desperate anger in Kaigaku that, in contrast to Zenitsu’s calm demeanor, drives home what truly has been lost throughout this saga.
Then we have Lucien Dodge as Akaza. Infinity Castle isn’t the first time Dodge portrays Akaza in a big way, but it is the most dynamic we’ve seen Akaza so far. Without giving too much away, I can say Dodge’s performance elevates Akaza’s arc. He gives Akaza’s story so much heart and passion. I’m going to be thinking about it for a long time to come.
Whether you watch Demon Slayer: Kimetsu no Yaiba Infinity Castle in English dubbed or subbed (or both), you are in for the experience of a lifetime. This installment plays out beautifully on the big screen and makes the wait absolutely worth it. The bar continues to rise yet again, and I can’t wait to see it surpassed in the next part.
Demon Slayer: Kimetsu no Yaiba Infinity Castle premieres in theaters, including IMAX® and premium large formats, in the United States and Canada on September 12, 2025, distributed by Crunchyroll and Sony Pictures Entertainment. You can get tickets here.
