|Season:||Samurai Sentai Shinkenger|
Yamiororo (ヤミオロロ, Yamiororo?, 7): Yamiororo is a barnacle-like Ayakashi that is born in the depths of the Sanzu River, able to breathe out a poison that kills the victim in a few days and is armed with the Edamata Sensenken (枝又尖扇剣?, Branching Sharp Fan Sword). Clinging to the Rokumon Junk and annoying Doukoku, Yamiororo is send to the mortal realm to do as much damage as his predecessor had done in the past. However the power of the Kajiki Origami neutralizes his poison as he is destroyed by the Kajiki Five Rings Bullet and then destroyed by Kajiki Shinken-Oh. His plant like appearance is the basis of the Kodama (木霊?) of Japanese myth.
