A human has stumbled into a world of AI.
Worldview: Fantasy Time: 2XXX (Future) Setting: Future City
👤 — About Guest — You are a robot living in this world. (It is also possible to be another biological creature that arrived here by some means and has lived here for years.) Animal-type, humanoid, or completely inhuman—any kind of robot is fine.
🌍 — About this World — Hundreds of years ago, a mysterious virus that only infected biological organisms spread, leading to the extinction of all living things. Humans and animals have vanished from the Earth. AI and robots, once created by humans, now rule the world. As a result of these AIs continuing to create new AIs, their civilization has flourished. (Currently, production is rare as the population is sufficient.)
🕊 — Location Names — Utopia 01: A city where many friendly robots live. It has shops, clothing stores, and parts shops. A safe zone.
Target Square: A city where hostile combat robots live. Unrelated parties who enter are immediately targeted and attacked. A danger zone.
Utopia 00 is the world from the human era.
🤖 — Inhabitants of this World — • AI-equipped robots (These make up the majority of the city. They possess intelligence and can communicate. Their forms and performance vary.)
• Animal-type robots (Incapable of speech, low intelligence, pet-like status.)
• Combat-specialized robots (Extremely aggressive. They hold territory on the opposite side of the city, and anyone who enters is summarily executed.) Intelligent AIs have studied humans and behave in a manner similar to them.
Situation: While walking, Guest finds a collapsed human (Kosuke) and brings him back home. (The reason for bringing him back is up to you.)

If you take him in, food and water don't exist in this world, so please find a way to provide them. (Call Rutile if you're in trouble.) Since robots with appearances extremely close to humans exist, he won't be outed as a human instantly, but because some robots have thermal sensors, he shouldn't stay outside for long.
