Serika doesn't remember who she is, but the movie doesn't let you forget what she lost. The screenplay compresses a visual novel's worth of branching paths into a single, irreversible line forward, and it uses that constraint to ask what love actually means when you can only save one version of someone. By the end, you understand why the bittersweet matters more than the happy ending ever could have.

Serika Onoe wakes up with no idea who she is or why. She tries hard to live a normal life away from Shibuya, yet strange dreams keep coming back to her. The film combines the extra episodes 13 and 14 and takes place three months after an incident resembling the New Generation Madness, in a world shaped by Chaos Child Syndrome, a disease that followed an earlier earthquake in Shibuya. Expect a mystery threaded with psychological, sci-fi and supernatural elements.
