This latest series of adventures sees “Tanjiro” and “Nezuko” drawn into the equivalent of an animated Escher drawing as both they and the Hashira have to face a formidable array of Upper Rank demons as they sink lower and lower into this perfectly detailed, fluid, abyss of a construction. With the ultimate battle against “Muzan” getting ever closer, they must first face the mighty “Akaza” who has not only a remarkable arsenal of quirks and skills, but also something hitherto unseen by our intrepid “Tanjiro” - bit how to defeat it? It’s a film that starts as we are used to, with end to end combat scenes but around the midway point, we flip the vinyl over and enter onto an altogether more informative path. We are being told of the tragedies that touched the life of “Akaza” before his demonic days. We learn of a time when he was capable of love and affection, but was in turn subject to the most heinous of betrayals that left his soul vulnerable to the temptations of a life where revenge on those who offended him (think “Anakin Skywalker” a little bit) when offered to him. It is good to see little more in-depth characterisation going on in this film, it helps us to balance the forces of good and evil and there is more than plenty action to keep the pace moving and avoid that backstory becoming too melancholic. The setting within the aptly named “Infinity Castle” challenges linear perspectives effectively with an effective sense of the multi-dimensional that allows the artists (and the CGI) to assume something gossamer-like as solid structures melt and what is down becomes up and gravity takes a back seat. It has some gore to it, and some scenes aren’t for the faint-hearted, but it’s the best yet of the “Demon Slayer” movies and stands alone, well.

Infinity Castle is a breathtaking kickoff to the final Demon Slayer saga, and it wastes no time plunging us into the chaos. The animation is jaw-dropping, with Ufotable pushing their craft to dizzying new heights—fluid battles, haunting visuals, and a sense of scale that makes every frame feel monumental. The pacing is relentless but never empty, balancing spectacle with raw emotion as Tanjiro and the Hashira face their darkest trials yet. While it’s clearly setting the stage for an epic trilogy (with 2027 and 2029 still looming), this first entry stands tall on its own—delivering both tragedy and triumph in equal measure. It ends not with closure, but with anticipation, leaving you desperate for what comes next. A near-perfect blend of heart and spectacle.
