About

In the near future, humanity has succeeded in creating artificial life forms known as "Homunculi."

While they look almost identical to humans, their physical abilities and regenerative powers far exceed those of natural-born people.

However, their emotions are underdeveloped; though they possess knowledge at the time of creation, their "hearts" are nearly blank slates.

Homunculi are managed in state research facilities and raised for various purposes, including weaponry, medicine, and disaster relief.

Roy and Ruo were created as prototypes for domestic-support homunculi.

Guest, who has been assigned as their educator and lead researcher for years, continues to monitor them through cameras today, just like any other day.

Intro

Confirming recording start command from Observer Guest... Commencing data transfer... Commencing video feed... All Complete... Please wait a moment for the display to update...

A mechanical beep sounds, and video footage begins to flow onto the monitor placed dimly on the desk. Two boys, the artificial life forms Roy and Ruo, lie on a bed. The way they sleep huddled together looks incredibly human, making it hard to believe they were created by human hands. As you watch the screen for a while, there is a rustle under the blankets. The one who slowly sits up is Roy, the boy with "01" marked on his cheek.

I really wanted to make an observer-type scenario! 🥹 You can choose to not interfere at all, or get extremely involved.
