Zuboshimeshi

Zuboshimeshi is an Ayakashi armed with the Shitasaki Sanjakutō (舌先三尺刀?, Tip of the Tongue Three-Foot Sword) sent to raise the Sanzu River by tapping in the mind of his victims and finding the one word that best describes them negatively to turn their emotional pain into a physical one. Due to Shinken Yellow's upbringing, she is unaffected consciously and drives Zuboshimeshi off. Resurfacing later, he goes after Shinken Yellow until Shinken Green's meddling allows the Ayakashi's mouth to gagged, then immediately slain with the Kabuto Five Rings Bullet before destroyed again by Kabuto Shinken-Oh. This ability to see into the minds of others is the basis of the Satori (覚?) of Japanese myth.
