Plot Summary

In the not too distant future androids have come into common usage. Taking the androids for granted, humans treat them as if they were common everyday tools, while on the other hand, some people empathize with androids due to their human-like appearance (save for a digital ring floating above their heads). This has become a social problem and these people are frowned upon as a result. Rikuo, one who has taken androids for granted for his entire life, one day discovers that Sammy, his home android, has been acting strangely and finds a strange phrase recorded in her activity log. He, along with his friend Masaki, traces Sammy's footsteps and come upon an unusual café.
