Paradise Lost
This article is about a/an rider/orphnoch in Kamen Rider 555.

For the A.R. World version, see Kenji Sakata.

Yuji Kiba (木場 勇治 Kiba Yūji) was a young man who became the Horse Orphnoch (ホースオルフェノク Hōsu Orufenoku) who was friends with Takumi Inui. Following the deaths of his Orphnoch friends and the supposed "betrayal" of Mari Sonoda, Kiba briefly turns on humanity and used one of the Emperor Belts, becoming Kamen Rider Orga (仮面ライダーオーガ Kamen Raidā Ōga, Masked Rider Orga).


Paradise Lost

Kiba was the primary user of the Orga Gear. In the events of the film, Yuji Kiba was tricked and abducted by the Smart Brain corporation into believing Mari Sonoda has betrayed him, later chosen to be the user of the Orga Gear, allowing him to transform into Kamen Rider Orga. The Orga gear was recorded as the fifth Rider Gear created by Smart Brain, after the Faiz and Kaixa Gears were stolen by the humans and the Riotrooper gear had undergone mass-production. Created alongside the Psyga Gear, the Orga Gear is regarded as a "perfect" gear, and therefore it can only be worn by Orphnochs. Kamen Rider Orga has a more ornate appearance than any of the previous Gears, the Rider form having robes made of Soul Foam for a majestic appearance. Orga is armed with the Orga Stlanzer sword which he uses in the Orga Stlash Exceed Charge. He is sent to fight Kamen Rider Faiz after Psyga is defeated. Faiz is finally able to defeat Kamen Rider Orga with Blaster Forms Rider Kick, but does not kill him. Instead, Orga dies while trying to hold off the Elasmotherium Orphnoch so Faiz can destroy it, after Takumi finally gets through to him and reminds him of what Smart Brain really stands for and what his true values are.

Kamen Rider Decade

Kamen Rider Orga appears with other kamen Riders commanded by Wataru Kurenai, but all are murdered by Decade in the episode 1 of Kamen Rider Decade in the dream of Natsumi Hikari and then concluded the dream with Decade as only Rider in the Rider War. Rider War

The Destroyer of Worlds

All the Riders killed by Decade.

In the special version of episode 31, Kamen Rider Orga is seen as one of the many Kamen Riders who fought in the Rider War against Decade and were all destroyed.

During the events of Episode Yellow: Treasure de End Pirates, Kamen Rider Diend Complete Form summons Orga alongside seven other Movie Riders using the Attack Ride Card Gekijouban to defeat Kamen Rider G Den-O.  Here, Orga uses Orga Stlash, possibly in order to better go along with the other Riders' ranged finishing moves (as occurred with Kamen Rider Glaive's Gravity Slash).

Violent Emotion

Violent Emotion


Ability Parameters:

The movie version of Horse Orphnoch's design called Violent Emotion (激情態 Gekijōtai) is dramatically different than that of the TV series. It now sports a more helmet-like head design as the horse snout is pushed upward to evoke a more human-like face. The singular horn's enlarged and moved toward the top of its head while its white mane extends much fuller all the way down to the base of its neck/back. The hoof design on its chest is replaced by a larger and more powerful chest armor.

In the Paradise Lost ending, Kiba was deceived into using the Orga Gear to fight Faiz, but aided him and died from injuries sustained by the Elasmotherium Orphnoch. However, he was able to wound it enough for Faiz to finish it off.

Rider Statistics

Ability Parameters:

Kamen Rider Orga (仮面ライダーオーガ Kamen Raidā Ōga) exists in a world where the Orphnoch have taken over the planet and the humans are slowly being exterminated. The Orga Gear was recorded as the fifth Rider Gear created by Smart Brain, after the Faiz and Kaixa Gears were stolen by the humans and the Riot Trooper gear had undergone mass-production. Created alongside the Psyga Gear, the Orga Gear is regarded as a "perfect" gear, and therefore it can only be worn by Orphnoch. SIC Hero Saga Kamen Rider 555 further explain that Orga Belt was originally created from the original Delta Gear that was retrieved by the Rose Orphnoch from Mihara.

Kamen Rider Orga has a more ornate appearance than any of the previous Gears, the Rider form having robes made of Soul Foam for a majestic appearance. Orga appeared to have immense strength on par with Kamen Rider Kaixa, however it appears to be much slower than Faiz. Unlike Psgya, the Orga gear's weapons are still visible while not transformed, although Orga's sword, the Orga Stlanzer, is not disguised as an everyday household item.

The Orga Gear was given to Yuji Kiba after he had been fooled into thinking he had been betrayed by the humans. He only transformed with the Gear once however, before he was killed by the Elasmotherium Orphnoch and the Orga Gear self-destructed.

Kamen Rider Orga's finishing attack is called the Orga Stlash (オーガストラッシュ Ōga Sutorasshu), in which the Orga Stlanzer extend a Photon Blood-energy blade which can either counterattack or capture a target before destroying it.

Armor Information

The Orga Armor has several key features in its design. Unlike the Gear, the armor does not exist until the wearer transforms.

  • Full Metal Lung: The chest armor of the Rider provides the most protection, being able to withstand light Anti-tank weaponry.
  • Orga Core: In the center of the Full Metal Lung is a large glowing red dome. This is the primary reservoir of Photon Blood.
  • Photon Blood: A glowing substance that provides all of the Rider’s powers and generates all of the physical features of the armor. The Photon Blood is generated from the Orga Driver. Orga produces even more Photon Blood than Psyga.
  • Omega Streams: The path that the Photon Blood travels through the Rider’s armor. In Orga, this path is gold.
  • Photon Terminals: Where the Photon Streams connect with the gauntlets and greaves.
  • Sol Foam/Metal: Soft parts of the armor are made of Sol Foam, and the hard parts are made of Sol Metal. This substance is generated by the Orga Driver to form complex machinery that is powered by Photon Blood. If the Foam or Metal are damaged, the armor switches off and resets itself.
  • Crystal Scope: The large eyepieces of the Rider give them incredible vision. They can see in darkness with no problems and have a limited amount of x-ray vision.

Appearances: Paradise Lost, Decade Episodes 1 ,7 (Flashback) ,31 (Special Version) , Treasure de End Pirates, Kamen Rider Drive show Episode 4 ,Special Event, Heisei Generations FOREVER (as a toy).


  • Horse Sword: His principal weapon used in his Orphnoch form.
