In the Japan of tomorrow, using androids for many tasks is completely normal. Yet considering them equal to people is discouraged, and constant worry lingers about the chance that machines might rebel against their owners. Those who trust their androids too much are scolded and called "dori‑kei," meaning android‑addicts.
High schooler Rikuo Sakisaka notices his home robot, Sammy, acting oddly—she has been leaving the house without his orders. Checking her movement records, a mysterious entry catches his eye: "Are you enjoying the time of EVE?" With his friend Masakazu Masaki, Rikuo follows Sammy to a café named Time of Eve, where patrons are forbidden from showing bias toward each other. He realizes the place is visited by both humans and robots, indistinguishable from one another.
Every guest—from the lively Akiko to a bot on the brink of failure—carries their own tale and obstacles. While Rikuo seeks to uncover Sammy"s motives, he starts doubting the rationality of the fear that pushes people to view androids merely as tools. He wonders whether society"s fear is justified or merely a reflection of its own insecurities, and he resolves to investigate further, hoping to bridge the divide between creator and creation for a future.
