Amane Kurihara

Amane Kurihara is Haruka's nine year-old daughter (10 in episode 13) and Kotaro's niece. She is a rude girl who treats only Hajime nicely. She also treats her own uncle, Kotaro, as a small idiot, even calls him by name. She is the reason that Hajime discovers what it means to be human.

In the Missing Ace ending, a heart-broken Amane became a sukeban at age thirteen. Albino Joker uses her for the Vanity Card but then she is saved by Hajime, who sacrifices himself in order to defeat Jashin-14.

She returns in Kamen Rider Zi-O.
