Following a series of baffling vanishings that began to afflict a train, the Demon Slayer Corps' repeated efforts to resolve the issue failed. To stop further losses, Flame Pillar Kyoujurou Rengoku decided to confront the menace himself. He is joined by some of the Corps' brightest newcomers—Tanjirou Kamado, Zenitsu Agatsuma, and Inosuke Hashibira—who are eager to see the legendary slayer's blazing prowess up close.
Little do they know that the demonic agents behind the disappearances have already activated their cruel scheme. In this malevolent presence, the party must summon all of its resolve and unsheathe blades to protect every one of the two hundred passengers aboard. As chaos escalates, Tanjirou's determination and sense of duty are severely tested. The platform lights dim, and the train's engines sputter as passengers cling to each other.
