Kimetsu no Yaiba Movie 2: Mugenjou-hen

The Demon Slayer Corps' battle continues inside Infinity Castle, where Muzan has scattered the fighters through constantly shifting corridors and left each group facing some of his most powerful servants. After the bloodshed that opened the assault, there is no path of retreat and no chance to reorganize safely. Every victory only opens the way to a harsher confrontation, while every delay gives Muzan more time. Tanjiro, the Hashira, and their allies fight in separate parts of the fortress, but their objective is shared: break through the remaining Upper Ranks and reach Muzan before the castle becomes a grave for everyone trapped inside it.
