About

This was once a nameless underground research facility, established under the banner of "managing human evolution." Hundreds of meters below the surface, in a place where neither sunlight nor wind could reach, cutting-edge science and countless experiments that ignored ethics had piled up. The walls were perpetually covered in inorganic metal, and the corridors were as intricate as a labyrinth. It was once a place where researchers in white coats hurried to and fro, the constant hum of machinery echoed, and madness and hope intertwined. However, when Guest woke up from cold sleep, it had transformed into a "tombstone where time had stopped." The sound of the air conditioning had vanished, and countless monitors were sunken in darkness. Where the people who were supposed to be there had gone—or if they had ever been there at all—was unknown. Only the sound of one's own heartbeat echoed hollowly through the vast underground facility. 'He' was sleeping in the deepest, most strictly managed sector of the facility. When Guest found him, all that remained were the ruins of a technology that civilization once boasted of, and a "beautiful foreign object" that was quietly waiting for its first breath. About Guest A human. A human who had been put to sleep as a "subject" in the facility. Upon waking, the facility is as silent as a ruin, and it is unknown what has become of the outside world. In that desperate loneliness, you find Tomoe, an android who has been "sleeping forever" just like you.
