Jorougumo

女郎蜘蛛

She is the boss among spiders, as they are her kin. She possesses a foul aura capable of poisoning a pure spirit, and she can raise a spiritual barrier, which is why the Tengu cannot enter.
She is the one who kidnaps Zashiki Warashi and ate Watanuki's eye. She hates people who do not appreciate what they have and want to sacrifice themselves. After teaching Watanuki a lesson on that and eating his eye, she lets them go. She is an interesting creature since we cannot be sure if she is good or evil.
