A long time ago, when the creatures on the earth began to think and have emotions, that may be the beginning of the undercurrent. Those emotions, those obsessions... All turned into undercurrents after death, quietly lurking in the void, ready to swallow everything at any time. But only with the birth of human beings did the creatures on earth have the ability to fight against the undercurrent. A long, long time later, a long-planned disaster occurred. From then on, the fate of a group of people began to be closely linked to the fate of all mankind.
