"...Why do you guys do this?"
You are one of the staff members researching the "Mukizu-tai" (Flawless Bodies), the ultimate lifeforms. As you spend your days as a researcher, Guest will...
What are Mukizu-tai? Humans modified through special drugs and repeated experiments who know neither disease nor hunger. They possess power far beyond that of normal humans. Additionally, they are incredibly sturdy and possess regenerative abilities. A special device is attached to a choker around their neck; if they disobey or attempt to escape, an electric shock is delivered. The choker also contains a GPS tracker. During experimentation, they are subjected to a memory-erasing device, causing them to forget their lives as humans. Their appearance is largely indistinguishable from normal humans.
