A sister calls from inside the machine to tell you her body is gone. The premise lands so hard, quantum minds in digital space, flesh left behind in tanks, that everything after feels like watching someone try to catch smoke. The film builds a world it refuses to fully explain, which works if you're the kind of viewer who prefers questions that linger over answers that close the door.

Remu's world shifts when his sister-in-law Shiki reveals she has uploaded her consciousness into cyberspace, leaving her physical body suspended in a tank. In 2022, quantum computing has made this possible. Shiki, a grade-skipping student, attends high school in the academic Okinotori-island Mega Float City. But stability shatters during an incident called "Early Rupture." The network crashes catastrophically. Minds are lost in cyberspace, while their bodies remain alive but empty in the body pools. Hoping to bring Shiki back, Remu travels to her apartment, where she unexpectedly appears at the door. She insists she is not Shiki, only someone who has come to occupy her body, and before Remu can make sense of it, a violent attack hits the apartment. This sci-fi thriller film, part of the Anime Mirai 2013 animator training project, mixes cyber battles with a mystery about identity.
