This article is about a/an rider system/rider form used by several identities in Kamen Rider Den-O.
For the Hibiki rider with a similar name, see Yūki.

The movie Saraba Kamen Rider Den-O: Final Countdown introduces a new system, Kamen Rider Yuuki (仮面ライダー幽汽 Kamen Raidā Yūki, lit. "Miasma"), an evil Kamen Rider system used by those who have control over the Ghost Train (幽霊列車 Yūrei Ressha), a skull-faced steam-engine that transcends the world of the dead and the flow of time.


  • Shiro - user of the Hijack form.
  • Ghost Imagin - user of the Skull form. Has a physical form, but chooses to taunt the Tarōs with Ryotaro's body.
  • Ryotaro Nogami - captured and possessed by the Ghost Imagin to act as a shield as well as for the 'poetic justice' of having him wipe out his entire ancestry.
  • Kamen Rider Yuuki (Another World) - Another World counterpart

Plat Form (プラットフォーム Puratto Fōmu) is Yuuki's most basic default form undersuit, which is briefly seen during Yuuki`s transformation sequence before the Aura Armor and the Denkamen facemask attaches.

Skull Form (スカルフォーム Sukaru Fōmu) is the form of Yuuki that is accessed when Ryotaro Nogami is possessed by the Ghost Imagin. In Skull Form, Yuuki's Full Charge is the Terminate Flash (ターミネイトフラッシュ Tāmineito Furasshu) using the sword of the Ghost Imagin. As the name and design implies, Skull Form's motif is the skeleton.

Hijack Form (ハイジャックフォーム Haijakku Fōmu) is the form of Kamen Rider Yuuki that Shiro accesses on his own. Hijack Form has a black and red color scheme, compared to Skull Form's black and gold color scheme, lacking the skull-theme. Hijack Form also performs the Terminate Flash, but does so with his SavageGasher (サヴェジガッシャー Saveji Gasshā) sword, which is a reconfigured DenGasher.


Yuuki Belt

Like Den-O, by using the Rider Pass (ライダーパス Raidā Pasu) and the Yuuki Belt (ユウキベルト Yūki Beruto), A-Ryotaro and Shiro are able to transform into Yuuki.

Ghost Train (幽霊列車 Yūrei Ressha) is a skull-faced steam-engine that transcends the world of the dead and the flow of time.


  • Though identified as one Kamen Rider, like Kamen Rider Den-O, Yuuki is actually more than one character.
  • The Yuuki Rider suit is composed of recycled parts from Kamen Rider Gaoh.
