|Season:||Samurai Sentai Shinkenger|
Narisumashi (ナリスマシ, Narisumashi?, 15): Narisumashi is an happy go-lucky Ayakashi with the ability to assume the guise of another, armed with the Urizane Fukusōtō (瓜実複相刀?, Melon Diploid Sword) that can split into two. He assumed Chiaki's form to cause trouble among the team, intending to kill the confused and depressed Chiaki once he complete his plan. However, seeing his reflection, Chiaki tricks him in order to expose him to the others. He was first destroyed by the Kabuto Five Rings Bullet and then destroyed by Tenku Shinken-Oh. His featureless face and shapeshifting powers are the basis of the faceless Noppera-bō (野箆坊?) of Japanese myth.
