Modern Japan. Imperial Heavy Industries has established a near-total monopoly on Automata — androids that have found their way into industry and ordinary households alike. High school student Yuto gets caught in an Automata runaway incident and nearly dies. He is saved by Nova, a third-generation Automata who brings him to her hideout. What Nova asks of him from there is serious enough that it changes the shape of what his days are going to look like.
