Urban legends have come to life, manifesting as phenomena called "Folklore." The mysterious Thompson Agency is dedicated to identifying and capturing these beings to minimize their harm to humanity. Thompson agents Emma and Yuliya are assigned to a sleepy branch in the countryside. While horrific atrocities are committed by Folklore in Tokyo, our heroes clean basements and fix the locals' toilets. However, it is in Folklore's nature to appear wherever humans gather. Myths, rumors, and fairy tales enter the minds of the public, then grow into fears that manifest on the streets, in the dark, and around every corner. When a factory owner calls upon the Thompson Agency to investigate a strange occurrence, he believes his workers are being superstitious. But Emma and Yuliya discover that something dangerous might have arrived to lick its wounds in their sleepy town—and it won't stay weak for long...
