Fog Tunnel Train—regular Platforms

The Kirigakure Tunnel, which has been closed for thirty years, only releases one green train at midnight. When entering the tunnel, you must abide by the five iron rules of survival. Those who violate the rules will be dragged into the boundless rusting dock, and all traces of their existence will be completely erased. Passengers in the carriage disappear out of thin air day after day, and faceless sailor stewards keep wandering between the aisles. I unexpectedly boarded the train carrying a lighter with a special origin, and slowly realized that the train's established rules of survival were themselves a carefully laid fatal trap. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
