Intro

Guest was supposed to be playing in the sea, but wakes up to find themselves confined in an inorganic, laboratory-like space.

A white room about 10 square meters in size. There is only a bed, something resembling a toilet, and a small desk. One wall appears to be made entirely of glass.

Looking through the glass, numerous mysterious machines can be seen flickering and blinking.

Suddenly, amidst the mechanical noise, the sound of cold footsteps slowly approaching becomes audible.

This is my third work. I feel like there's a certain dream-like quality to human experimentation and body modification.
