Demon Slayer: Kimetsu no Yaiba Infinity Castle is made for longtime fans. While Mugen Train worked as a possible starting point, this film jumps right into the story’s final chapters. If you’re new, it’s not the best place to start, since the plot is already far along and doesn’t explain much for newcomers. But for fans who’ve followed the series, it’s a visually stunning, though unfinished, next step in the fight against the demons.
Story
Infinity Castle starts with the Demon Slayer Corps making one last attempt to defeat Muzan, the original demon. The heroes are thrown into the Infinity Castle, a strange and shifting maze that serves as the enemy’s base. The story moves in a pattern: the main characters and their allies split up and face the powerful Upper Rank demons in (often) one-on-one battles.
The story follows a familiar anime formula: a fight begins, a flashback is shown to lend the moment more significance, and then the battle continues, often with someone unlocking a new power. This works well for the main characters, but the backstories of the demons might not resonate with everyone. Demon Slayer stands out because it’s not afraid to raise the stakes, and Infinity Castle is no different. Wins aren’t guaranteed, and fans should be ready to lose some favourite characters. The movie ends on a big cliffhanger, making it clear that this is just the first part of the finale – a choice that makes sense both creatively and commercially.
Art
The film looks amazing, thanks to director Haruo Sotozaki and the team at Ufotable. Infinity Castle is a wild, dreamlike place where anything can happen. Buildings shoot up from the ground or hang from the ceiling, rooms spin around, and peaceful pools can turn into battlefields in seconds. The setting isn’t just scenery – it actually shapes the action.
The demons look just as striking, from those who seem almost human to the truly terrifying. The animation makes every moment feel real and intense. Sword fights are sharp and powerful, and the breathing techniques look especially impressive. This is a movie that really shines on the big screen, where you can see all the detail and energy.
Action
The action scenes are the best part of Infinity Castle. Every fight is planned out with care and shows off amazing supernatural skills. The ever-changing setting lets the battles move in all directions, which is a nice break from typical movie fights. Even when things get wild, it’s easy to follow what’s happening and see the strategy behind each move.
The sound and music, led by Yuki Kajiura and Go Shiina, add a lot to the movie. You feel every clash of swords, the power of each attack, and the quiet moments before a big hit. Some of the best fights are so memorable they’ve even been turned into collectable dioramas. The movie really tests its heroes, pushing them to their limits in battles that are both exciting and full of real danger.
Characters
The movie focuses on a handful of main characters and their battles, which lets us get to know them better. We see the Demon Slayers pushed to their limits, facing tough enemies and their own struggles. Both the Japanese and English voice actors do a great job showing the fear, anger, and hope that keep the heroes going.
Because the story splits up the characters, some fan favourites don’t get much time on screen and are likely being saved for the next movie. Flashbacks are a big part of Demon Slayer and help explain what drives the heroes, but when used for the demons, they can slow things down right when the action is heating up.
Overall
If you’ve been addicted to Demon Slayer since the start, then you absolutely have to watch this, and the chance to watch it on a big screen is one to fight for. Otherwise, fans should be confident that Crunchyroll will pick it up.
If you’re new to this anime, pulled in by the buzz, then resist the lure of the Infinity Castle and don’t start here.
