Anime fans, rejoice! The highly anticipated Demon Slayer: Infinity Castle movie is officially set to hit UK and Irish theaters on September 12, 2025. This marks the beginning of an epic trilogy adapting the final arc of Demon Slayer: Kimetsu no Yaiba, bringing fans a breathtaking cinematic experience like never before.
With ufotable once again delivering its signature stunning animation, fans can expect jaw-dropping battles, emotional moments, and a story that will leave a lasting impact. Here’s everything you need to know about the biggest anime movie event of 2025!
What is the Infinity Castle Arc in Demon Slayer?
The Infinity Castle Arc is the final battle between the Demon Slayer Corps and Muzan Kibutsuji, the Demon King. After years of fierce battles against the Lower and Upper Moon demons, Tanjiro Kamado and the surviving Hashira launch an all-out attack on Muzan’s stronghold—an ever-shifting labyrinth known as the Infinity Castle.
Unlike any battlefield seen before in Demon Slayer, the Infinity Castle is a nightmarish domain designed to disorient and destroy its intruders. The arc is packed with high-stakes duels, shocking betrayals, and heart-wrenching moments that lead up to the ultimate showdown.
Where Did the Story Leave Off?
The last installment of Demon Slayer, The Hashira Training Arc, saw Tanjiro and his allies undergoing intense preparation for their inevitable war against Muzan. However, their training is cut short when Muzan invades the Demon Slayer headquarters, forcing the Corps into battle earlier than expected.
This confrontation leads to their dramatic descent into the Infinity Castle, setting the stage for one of the most thrilling arcs in the series.
