Zuboshimeshi is an Ayakashi armed with the Shitasaki Sanjakutō, 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 ShinkenYellow's upbringing, she is unaffected consciously and drives Zuboshimeshi off. Resurfacing later, he goes after ShinkenYellow until ShinkenGreen's meddling allows the Ayakashi's mouth to gagged, then immediately slain with the Kabuto Five Rings Bullet before being destroyed again by Kabuto ShinkenOh. His ability to see into the minds of others is the basis of the Satori (覚) of Japanese myth.
- The words that he used to defeat the Shinkenger were:
- Ryunosuke: father-complex/mother-complex
- Mako: old hag
- Chiaki: the leftover one
- Takeru: liar (in body and soul)
- Negatron, his Power Rangers counterpart from Power Rangers Samurai.
