Yuto Sakurai (桜井 侑斗, Sakurai Yūto) is a man who mysteriously disappeared prior to the beginning of the series, Kamen Rider Den-O, but reappears during the show proper as fellow time-travelling Kamen Rider Zeronos, partnered with the Imagin Deneb. As Zeronos, Yuto and Deneb possess formidable strength, but it comes at a price: the green pass cards that enable transformation into Zeronos (and the red ones that allow him to assume Zero Form) erase people's memories of Yuto as they are consumed.
It is eventually revealed that Yuto is exploiting this fault in Zeronos's system, attempting to erase all traces of himself from his and Ryotaro Nogami/Kamen Rider Den-O's present to prevent evil Imagin from hunting his fiancee Airi Nogami and the child they will eventually conceive - Den-O's plucky little girl sidekick Hana.
