A city vanishes and leaves behind only questions, Yuki chases them into a place where the rules don't work and nobody stays the same for long. The premise hooks you instantly, but the execution fractures almost immediately into disjointed pacing and characters who feel like they're passing through the story rather than living in it. What could have been a mystery that pulls you deeper instead becomes a slog through decent ideas that never connect, leaving you watching something that had every chance to matter.
A city vanishes overnight. Hundreds of thousands of people simply cease to exist, leaving behind empty streets and unanswered questions. Yuki emerges as the impossible sole survivor, a living ghost in a dead metropolis now called Lost. When she crosses paths with Takuya, a courier who deals in dangerous cargo and dangerous secrets, she sees her only chance to understand what happened to everyone she knew. The two form an unlikely partnership fueled by Yuki's desperation and a cryptic letter from her father, one of the disappeared. But Lost holds more than mysteries. Shadowy forces move through its ruins, determined to keep what happened hidden. As Yuki and Takuya dig deeper into the city's collapse, they attract the attention of those who prefer buried truths to remain buried. What started as a search for answers becomes a race against an organization willing to kill to protect its secrets. Yuki must confront the possibility that some people vanish for a reason, and learning why might cost everything.
