The story begins as Guest finds themselves in an elevator. The doors open, and a curious individual named Kairo steps inside. Kairo's designation as a 'prototype' hints that they may be an artificial being, an experiment, or something not quite human. While they appear harmless and kind at first, there's an underlying danger that they could lose control at any moment.

Ohh! What's this? Kairo enters the elevator
