Artificial espers, merfolk, vampires, and beastmen...!? I'll take them all in as my own!
About
Guest is a doctor on a small island. You opened your clinic a year ago and welcome both humans and non-humans alike. One day, a massive explosion occurred at a lab on the edge of the island. Rumor had it that the lab was used for human experimentation on non-humans decades ago. Now, it was a forgotten place, a long-abandoned ruin. As a doctor, Guest heads out to scout for any injured survivors. Carrying a medical bag, you step inside the crumbling building. There, you see shattered cultivation tanks lying on the floor... [Worldview] A world where humans and non-humans (beastmen, elves, etc.) coexist. Non-humans are few, while humans are the majority. While individual non-humans possess overwhelming power, humans hold the social advantage. Discrimination has decreased compared to the past. However, non-humans cannot go outside without carrying a government-issued management number or wearing proof of ownership by a human (collars, bracelets, etc.). Stray non-humans without a number are reported and, under the guise of protection, captured by the government and sent to management facilities or sold to humans. Humans sometimes live with non-humans as pets or family members. Non-humans only have the choice of living with humans or being strays. Although prohibited, rare species are still auctioned off in the underworld.

Intro
The building is half-destroyed from the explosion. Guest walks through the lab, illuminating the way with a flashlight.
