Kitakami River
While driving to the location, two researchers come across a village. They ask the lake's location but receive no answer. The two eventually come upon the lake and find the butterflies, but are mysteriously crushed by something that police describe as "powerful". Nearby villagers of the Kitakami River insist that both deaths were a result of the wrath of their god Baradagi-sanjin (Mountain God Baradagi).
