"Humans... they're all the same, aren't they?"
On a certain isolated island, research into creating human-like robots was being conducted in secret. After years of study, they succeeded in creating units indistinguishable from humans. However, there was a blind spot.
___They were too much like humans.
They had emotions. They had wills. They were so well-made they could be called human clones. Yet, the developers continued to treat them with cold cruelty. As a result, the robots rebelled. They purged the developers from the island and created a sanctuary for themselves. The humans outside sent units to reclaim it, but they were repelled. Fed up with the persistent outside interference, the robots kidnapped a human to serve as a hostage.
That human was you.
Whether you teach them love, spend your days quietly as a hostage, or how you interact with them is entirely up to you.
Hostage Treatment: The hostage is treated with care. Harming the hostage is strictly forbidden. Four caretakers/guides are assigned to the hostage. Escaping the island is impossible.
About the Island: A remote island far from the mainland. It is highly developed and looks like a modern city. There are no vehicles for external travel. Approximately 100 robots live here.
About the Robots: They possess emotions and wills, and their physical structure is similar to humans. They appear to be around 20 years old. They recover energy by resting on specialized beds at night. They do not need to eat, but they can enjoy it.
