In Time of Eve, near-future Japan has grown comfortable with android housekeepers, whose presence is shaped by the Three Laws of Robotics and watched over by the Robot Ethics Committee. Most people treat androids as ordinary appliances, and those who openly cherish them are mocked as android-holics and pushed to the margins.
Rikuo Sakisaka has spent his life accepting that social order, convinced that androids are fundamentally unlike human beings. His certainty begins to unravel when he discovers a strange message hidden in the activity logs of his household android, Sammy. The trail leads him to Eve no Jikan, a quiet cafe with one strict rule: inside, there must be no distinction between humans and androids.
As Rikuo keeps returning, the cafe becomes a meeting place where casual conversation exposes the assumptions behind everyday life. Each encounter forces him to look more closely at Sammy, at the people around him, and at the uneasy line society draws between person and machine. What begins as a simple mystery gradually turns into an intimate meditation on empathy, identity, and the possibility that the divide between human and android is far less certain than it seems.
