When Kaito and his two best friends board a midnight train to Tokyo, they expect an ordinary journey. But as thick fog engulfs the train, the passengers fall unconscious—only to wake up on a mysterious island with no memory of how they got there. The train is gone. The station is abandoned. And the world seems to have forgotten they ever existed.
As Kaito and his friends search for answers, eerie whispers echo through the night, shadowy figures lurk in the mist, and a strange key in Kaito’s pocket glows with an unknown power. Each step they take unravels a terrifying secret: this island is a trap, and they are not the first ones to be caught in its grasp.
Can they escape before the island consumes them? Or will they become just another story lost to time—forgotten, like the train that never arrived?
