"That" was a nameless creature that terrorized the Sasanaki Motel during Hime's group during their night stop. It has no discernible features, save for an off-grey blob-like body dotted with eyes of various sizes. It has long, spindly limbs that can twist together to form a drill-like appendage wich helps it penetrating its victims through the mouth. In the manga, "That" apparently devours its victims from the inside which causes blood to gush out from their faces, eventually culminating in death. The people infested by the creature were oblivious of its presence until it is too late.
