Reverse:1999 Global enviroment

For the raindrops that are pouring down the sky Reverse:1999. Pedestrians and walls peeled and melted in the rain, and the world seemed to have entered a new old age. And everyone but you has disappeared after the "storm" of erosion. In a world where humans and occultists co-exist, there is a group known as the "Hands of Regeneration" who are dedicated to restoring the glory of occultism, and they seem to as both heretics and prophets.

What is certain is that their dormancy and dark movements are not unrelated to the birth of the "storm". You are called “Sichen,” and you are appointed by the “Saint Love Foundation,” an organization that specializes in the housing of mystics, as a witness of the times. You will patrol the cycle of time and find other mystical partners from different eras and countries to help them escape the storm.
