Gashadokuro:

1. Gashadokuro, because it is a skeleton yokai and Halloween is upcoming so I think its suits the Halloween theme.
2. The yokai Gashadokuro’s background story states that during wars, dead bodies weren’t able to be given a proper funeral so the souls from the bodies were not able to pass on so they were stuck as souls. The souls that were full of hatred and anger, that energy stayed on the bones of their corpse. When the bones of 100 people gather into one area an Gashadokuro is born
3. I think Japanese monsters are very different than normal monsters from the west because we over here have things like vampires and frankenstein while Japan has umbrellas with legs and ladies with long necks, and even gigantic skeletons.
4. I do not believe in ghosts or yokai because it is not realistic to me.
