|This article is about a/an episode in Kamen Rider Den-O.|
Yuto Sakurai's past self appears before Ryotaro to tell him to not try to be so reckless in his pursuits again as a violent Imagin suddenly makes its move in the present.
Ryotaro attempts to confront Yuto about his ties to the Sakurai he knew, only to be told that it was none of his business. Nonetheless, Ryotaro attempts to convince the Owner to let him enter the past. Meanwhile, a man named Kōhei Amano formed a contract with the Jelly Imagin to dig up a time capsule. Hana and Ryotaro both meet Yuto at Airi's shop, and an eventual confrontation between Momotaros and Deneb occurs, both possessing their respective hosts.
However, Deneb simply presents a peace offering, and so Yuto expels him from his body. Surprisingly, Deneb is able to take a physical form, implying that Yuto has a full contract with Deneb. Elsewhere, the Jelly Imagin attempts to fulfill his contract by forcing his contractor to do the work instead. Ryotaro attempts to fight the Jelly Imagin, but it eventually manages to escape.
He has another encounter with Yuto who tells him to stop interfering with time just to save people. As he reveals himself to be another Kamen Rider, he calls upon the ZeroLiner, leaving Ryotaro behind, once again confused.
