Kamen Rider Den-O

A Clockwork Fiancé (1x18)

:

Ryotaro is disheartened that he is not able to find the man he believed to be Yūto Sakurai, and the Wolf Imagin goes into hiding, infuriated that it is trapped in 2004 with nothing to target. After returning to the DenLiner, Ryotaro explains his reasons: the mysterious man who appeared in the past is actually Yuto Sakurai who had disappeared three years ago, making Airi lose her memories of him. While everyone lets Ryotaro rest, the Wolf Imagin decides to destroy everything and everyone out of frustration on April 8, 2004. Back on the DenLiner, Kintaros asks Ryotaro to give him a wish to grant so he can leave Ryotaro to relieve the physical strain on Ryotaro's body, with Momotaros and Urataros having the same notion themselves. Ryutaros simply reveals that Ryotaro had actually been training too hard. At first, Momotaros is reluctant to fight because Ryotaro was being sneaky, and only became Sword Form after he promised to be honest. Back in the present, someone tells Ryotaro to give up protecting time and searching for Yuto. He reveals a Rider Ticket and introduces himself as Yuto Sakurai.
