Mari Sonoda/Zi-O

Mari Sonoda (園田 真理) is Takumi Inui's partner who was attacked by the Elephant Orphnoch before Faiz's history was erased.

Kamen Rider Zi-O
In an alteration to history brought about by Time Jacker Ora transforming Ryuichi Sakuma into Another Faiz on October 25th, 2003, just as Takumi was about to save Mari from the Elephant Orphnoch, the Orphnoch were evidently erased from history while Takumi lost his identity as Kamen Rider Faiz.
