## Plot

   Ancient fossils sleeping in Fossa Magna have gathered together and transformed into a giant yōkai. The destination is Tokyo. Only the yōkai were aware of the truth about this invasion, which seems to modern humans to be a natural disaster. If nothing is done, the world will be destroyed. This can be stopped by Watanabe, an elementary school student in Tokorozawa, Saitama, who inherits the blood of the legendary monster hunter. Suddenly, the great adventure of the boy who was selected as the "hero who saves the world" and the yōkai who involved him begins now.
