Fan Casting Yuto Sakurai in Kamen Rider Den-O (English Dub)

Airi's fiance and Ryotaro's future brother-in-law, Sakurai was a gentle, kind-hearted man with a passion for astronomy he shared with Airi. The two were very much in love, and Sakurai treated Ryotaro like the little brother he never had; thus, Ryotaro's surprise when Sakurai disappeared just before the wedding is understandable, as is his confusion at the fact that nobody seems to remember his existence. Several times in the early part of the series, a cloaked man appears watching Den-O's battles in the past and checking a pocketwatch; by accident, Ryotaro bumps into the man and recognizes him as Sakurai. He attempts to track down the man, only to be warned off by Yuto.
