Namiayashi (ナミアヤシ, Namiayashi, 4): Namiayashi is a two-toned Ayakashi who is armed with the Aodake Dankatsusō (青竹断割槍, Green Bamboo Split Spear). Laidback and disturbing in personality, Namiayashi is sent by Shitari Honeno to increase the River by doing what he loves best, making others cry. Appearing in the mortal realm before a boy named Ryota, he accomplish his goal by tricking the boy with a false promise of seeing his grandfather again. His attack is the Tora Tsunami (虎津波, Tiger Harbor Wave), creating a tiger from the right half of his body and a Sanzu River wave from his left to take out two opponents. He is destroyed by ShinkenBlue and ShinkenPink, and then destroyed by ShinkenOh. His physical appearance and special attack make him the base for the Suiko (水虎) myth.
