Kimetsu no Yaiba Movie: Mugen Ressha-hen

After completing their rehabilitation training, Tanjiro, Nezuko, Zenitsu, and Inosuke board the Mugen Train, where dozens of passengers have vanished in a short span of time. Their mission places them alongside Flame Hashira Kyojuro Rengoku, one of the Demon Slayer Corps' most formidable swordsmen. The demon behind the disappearances is already waiting, however, and its attack does not begin with claws or blades. Trapped in an enemy's carefully crafted dream, each fighter is confronted with desires and memories powerful enough to make waking unbearable. With around two hundred passengers caught in the same danger, Tanjiro and his companions must break free before the train carries everyone toward disaster.
