魂を懸けろ！(Kajiri Kamui Kagura)

It was said that long ago, horrifying spider-like creatures known as the tsuchigumo roamed the land. Although they have been mostly wiped out by humans, there is one single piece of land that still belongs to the creatures of the olden times. The land we know as Japan is split in two by an ocean that runs down the middle, and on the eastern side of the island country is uncharted territory that is, to this day, still home to the tsuchigumo. Expeditions were made 300 years ago to acquire the eastern land and erase these creatures deemed as “outsiders,” yet none were successful. Worse yet, survivors of the expeditions seemed to have brought back “filth” and gave birth to “distorted” humans. No further expeditions were made, until recent political situations pressure for subjugation of the land.
