Chinomanako is an Ayakashi who manages to steal the Diendriver from Kamen Rider Diend (who stole the Ika Origami from Genta) and did not need the Sanzu River water. He becomes an "Ayakashi Rider" with his Chinomanako Diend Form, this universe's (the Sentai universe) first ever Kamen Rider, in a world that was supposed to be without riders. With all the crevices in the Diend helmet and armor, he can easily summon Nanashi footsoldiers. He also can use KaijinRide cards. Kamen Rider Decade and Kuuga team up with the Shinkenger to destroy this monster. He did not grow giant.
