Shiro

was a man who attempts to alter time to switch the worlds of the living and the dead through the as Ryotaro Nogami's abduction allows it to traverse time like the DenLiner. He has an obsession with Sora and cannot bring himself to do anything that he perceives would make her cry. However, Shiro is the true who can revive both Imagin and humans alike.
==History==
===Saraba Kamen Rider Den-O: Final Countdown===
Shiro appeared when Teddy discovers Shiro's plan to kill everyone in the village the next day, but is found out and attacked. He struggles back to their base of operations so his friends will know and says how the "elephant" is not really an elephant.
After Owner reveals he summoned Kotaro in response to a threat posed by the Ghost Train and its owner Shiro, who seeks to use the Ghost Train to reverse the worlds of the living and the dead. After Kotaro explains to Momotaros that intends to pick up the slack for his grandfather, whom he has no respect for, he goes after the Ghost Train by himself as New Den-O to fight Yuuki after killing the Phantom Imagin until Shiro arrives and defeats New Den-O personally. Yuuki is about to kill Kotaro when Ryotaro attempts to regain control over his actions as the Taros arrive. Although Shiro and Yuuki escape, the New DenLiner crew get a Rider Ticket and a partial message from Ryotaro to Momotaros about protecting an "elephant" that leads them to where Shiro intends to carry out his plan: May 23, 1729.
Den-O easily takes out the Ghost Imagin as Shiro takes the Yuuki Belt and assumes Yuuki Hijack Form as he uses his necromancy to summon every Imagin the Riders have ever faced back from the dead.
====Battle with Den-O====
Kamen Rider Yuuki Hijack Form is a very powerful Rider. Yuuki summons all of the past Imagins Den-O defeated during the TV show. Momotaros, Urataros, Kintaros, Ryutaros, Sieg, Yuto, and Ryotaro transform into their respective riders. Yuuki retreats by horse as Sword Form and Liner Form give chase. As Yuuki stops at a battlefield, he turns around, knocking the two Den-O forms off their horses. As Yuuki makes his final move, Teddy arrives and stops him from doing that. Kotaro arrives and transforms into Kamen Rider New Den-O Strike Form. After a sword battle, Den-O Sword Form and Liner Form grab onto Yuuki's arms. New Den-O activates Full Charge, and while he does that, Sword Form and Liner Form activate their Full Charges, powering up their swords. The Riders defeat Yuuki and Shiro slowly dies, while Sora stays by him saying her final words as she leaves in the Ghost Train.
It is this point in history that Shiro planned to negate, forcing Ryotaro to kill his ancestors thereby preventing Ryotaro from ever existing would have created a paradox great enough to destroy all of time, thus allowing him to bring Sora and everyone else who had died back to life. With his mission complete, Kotaro gains a new respect for his grandfather as he and Teddy are brought back to their time via the DenLiner, where they meet up with the elderly Ryotaro of their future.
