A smartphone crack is the only bridge between the world you know and a Yokohama that shouldn't exist. The photo of yourself you never took is already waiting for you there, proof that something has been documenting your life from a place you can't reach. Escape means answering the question that should terrify you most: if that photo exists, what else has it captured?
Shiori tumbles down a staircase and her phone shatters. When she comes to, the world around her has twisted into something wrong. Yokohama still exists, but it's hollow. Empty. Wrong in ways she can't quite articulate. Then she notices it: a photo on her phone. It's her. She's wearing clothes she doesn't own, standing in places she's never been, posted to an account she recognizes as hers. Except she never took it. The photos keep appearing. Each one pulls her deeper into this fractured reality, each image a breadcrumb leading nowhere. Shiori realizes her smartphone isn't just a device anymore. It's become a map of a labyrinth, and she's trapped inside it. The question isn't what took her here,it's whether the person in those photos is actually her at all, and if finding the source means finding her way home, or losing herself completely.
