Demon Slayer: Kimetsu no Yaiba - The Movie: Mugen Train

Tanjiro, Nezuko, Zenitsu, and Inosuke join Flame Hashira Kyojuro Rengoku aboard a train where dozens of passengers vanish. Lower Rank demon Enmu traps the team in crafted dreams that offer perfect lives, forcing each to sever illusions to wake and protect the cars. Battles occur on moving carriages as sleep and reality blur. When the train is secured, a stronger foe arrives, pushing Rengoku to hold the line alone until dawn. The outcome defines the hunters’ next steps: grief, renewed training, and a clearer measure of what it will cost to reach the demon responsible for all others.
