Demon Slayer Kimetsu No Yaiba Infinity Castle Review: A Stunning First Step Into The Franchise’s Epic Finale!
Ufotable table delivers yet another masterpiece in all it's shonen glory.
4 / 5
The Demon Slayer anime stands tall as one of the genre’s modern pinnacles. Based on the manga by Koyoharu Gotoge serialised in Weekly Shonen Jump magazine, the anime gained a cult following right after its release. Now, the journey of Tanjiro and the Demon Slayer Corps is gearing up for its grand finale, a movie trilogy promising to tie up every loose end with blood, redemption, and justice. Demon Slayer: Kimetsu no Yaiba Infinity Castle, the first film of the instalment, follows the characters inside the titular Infinity Castle, which is equal parts stunning and haunting. Directed by Haruo Sotozaki, read on to know our thoughts on the film!
Plot Of Demon Slayer: Kimetsu no Yaiba Infinity Castle
The plot for the film picks off right after the end of season 4. Muzan, after recovering from Kagaya Ubuyashiki’s brutal trap and subduing Tamayo. Muzan retreats into his dimensional stronghold, the Infinity Castle. A pocket dimension where gravity bends, rooms collapse endlessly, and every corridor feels like a boss-level dungeon. Within this eerie domain, the Demon Slayer Corps faces wave after wave of Muzan’s most vicious demons. The stakes soar higher than the collapsing castle walls themselves of the Castle.
Visuals And Animation
The greatest strength of Demon Slayer has always been its storytelling and god-tier animation. Ufotable has set a standard, and the bar is only getting higher with this film. 3D has always been a touchy topic in the anime community, with multiple failed attempts that we have all buried in the back of our minds. However, with the infinity castle, the studio blends both 3D and 2D so seamlessly that every scene of Demon Slayer: Kimetsu no Yaiba Infinity Castle is a visual treat that will have your jaw on the floor.
Highlights Of The Film
Demon Slayer is known for turning combat into high art, and this film doubles down. Zenitsu’s face-off with Kaigaku is easily one of the best thunder-breathing showcases of the character yet. The reveal of his surprise Seventh Form had the entire theatre erupting in applause, and rightfully so.
The centrepiece of the film, however, belongs to the showdown between Tanjiro and Giyu versus Akaza, the demon responsible for murdering Renguko in the Mugen train arc. The two give their all to defeat the absurdly powerful demon, but it’s not only the extremely detailed and stunning fight scenes that will stay with you, but also the gut-wrenching backstory. The music pairs perfectly with the oscillating catharsis and carnage of the film. The voice actors from Natsuki Hanae to Kana Hanazawa, as always, do a brilliant job in bringing soul to the characters.
If there’s a misstep in the film, it’s the pacing. This may not be a problem for fans of the franchise since it’s the same classic storytelling formula of the anime, but the constant back and forth and the flashback-heavy plot of the film can get tiring at times. The film also dives straight in after the events of season 4 without offering much exposition, so watching the film with knowledge of the anime’s lore is heavily recommended.
Verdict – A Feast For Fans To Indulge In
Demon Slayer: Kimetsu no Yaiba Infinity Castle is the first blade strike in what promises to be the franchise’s climactic endgame. While much is left unresolved for the next two instalments, this film proves that Ufotable and Gotoge’s world is still unmatched when it comes to worldbuilding and narratives. The film echoes the same sentiment; behind the flashy breathing forms and blood-soaked duels, the heart of Demon Slayer: Kimetsu no Yaiba Infinity Castle asks one haunting question. What does it mean to be human, and at what point do we lose our humanity?
