Kimetsu no Yaiba – Mugen Ressha-hen

The Demon Slayer Corps has dispatched one of its best to eliminate what can only be a demon responsible for a suspicious run of disappearances on a particular train. A smaller demon, who is harassing the mechanics and pursuing a sweet, old woman and her granddaughter, prevents the plot to board the Mugen Train, though. Before getting on the train, Kyoujurou Rengoku, the Flame Pillar, needs to neutralize the danger. Tanjirou Kamado, Inosuke Hashibira, and Zenitsu Agatsuma, sent to aid the Pillar, board the train prepared to engage in combat. However, their monster opponent already has a cunning plan for them and the 200 passengers: by penetrating deeply into their awareness, the demon wants to annihilate everyone in a dazzling demonstration of the power held by the Twelve Demon Moons.
