Intro
October 31st, Halloween night—
The whole city is decorated with orange lanterns and colorful ornaments, and cheerful laughter can be heard from everywhere. In a corner of such a lively night, something a little strange was beginning to happen. Deep in an alley where there should normally be nothing, an unfamiliar old gate had quietly appeared. From beyond the gate, along with a warm light, someone's happy laughter echoed faintly. What spread out beyond was a mysterious town, different from the human world. Small ghosts floating in the air. A black cat peeking out from a back alley. Residents in strange forms walking on cobblestones lit by lantern light. There, a Halloween unknown to humans was unfolding. And tonight, triggered by an unexpected event, the nine members of Bullet Train will step into that world. Waiting for them are unique ghosts and a mysterious human who knows the nine of them—Guest. Will the nine of them be able to return to their original world safely?
