"Do you know? A dream is the same as a curse. Those who fail are forever cursed. Or so I hear..."
―Kiba when explaining to another Orphnoch about dreams right before attacking him[src]

Yuji Kiba (木場 勇治 Kiba Yūji) was one of the primary characters that appeared in Kamen Rider 555. He mostly served as one of the antagonists and occasional protagonists in the series. He was a young man who became the Horse Orphnoch (ホースオルフェノク Hōsu Orufenoku) after dying as a result of a car crash, although he lived in a comatose state for two years. He has assumed a total of three Rider forms: two in the main series (Faiz and Kaixa) and one in the film Paradise Lost (Orga).


Kamen Rider Faiz

Originally human, Kiba became a Natural Orphnoch after dying within two years when he was in a coma as a result of horrific car crash which killed his parents. Once revived, Kiba was astonished by the horrific changes from his parents' death to overhearing that his uncle forsaken him and sold his family's company. Though it got worse when Kiba learns that his girlfriend Chie Morishita left him for his cousin named Kazuaki Kiba, he lost control when he confronts the new boyfriend as he assumes his Orphnoch form to kill him in a maddened rage before realizing what he had done and attempts suicide, finding himself in a Smart Brain owned mansion and meeting Smart Lady, explaining his current status. When he is called by Chie later, he is heartbroken when she names him the culprit in Kazuaki's murder, outrunning the police before he murders Chie out of scorn. After finding Yuka, Kiba meets with Smart Brain's temporary CEO Eiichi Toda, who reveals more information of the Orphnoch and Smart Brain's goal. After hearing the genocidal intent, Kiba quickly comes to deplore the organization's tactics and resolved to become an Orphnoch who will protect humans and fight Smart Brain. However, Kiba becomes a rival of Faiz, fighting him every time they encountered one another until they learned each others' true identity and intent.

Unfortunately, Kusaka uses the Faiz Gear to trick Kiba to think that Takumi is a bad guy. He also lies to Takumi that Kiba is the one who stole the Faiz Gear, making both Kiba and Takumi become rivals once again. However, after knowing that Takumi is Wolf Orphnoch, Kiba starts to reconcile with Takumi. Unfortunately, Takumi loses his confidence and gives the Faiz Gear to Kiba for a short time. Kiba becomes Faiz for some time until he saves Takumi from his near death from Kyoji Murakami. He later gives back the Faiz Gear to Takumi.

Kaixa holds Arc

Kiba as Kaixa holds Arc Orphnoch.

After he believed Yuka to have been killed by the police, Kiba turns against his ideals and eventually replaces Murakami as the chairman of Smart Brain. He later kills Kusaka and claims his Kaixa Driver. Kiba eventually fought Takumi, and Kiba was defeated. However, Takumi didn't finish him, since Kiba was still a human. Kiba then revived his faith in humanity again and helps Takumi and Mihara fight the Arch Orphnoch. In the end, Kiba was mortally wounded by the Arch Orphnoch, grabbing the monster to allow Faiz to kill them both, though only the Arch Orphnoch barely survived.

Kamen Rider 555: Hyper Battle Video

Yuji, Yuka and Naoya are given a boom box by a rapping Smart Lady who reveals that it's part of a new plan by Smart Brain to invoke people into singing all over Japan. The reason: To get the three Rider Belts back.

Takumi and Mari are suddenly transported to another dimension of sorts with Yuji, Yuka and Noya now in flashy outfits and Smart Lady still rapping with three revived Orphenoch.

Mari then reveals the Faiz Sounder, the boom box that Smart Lady had been using as part of the plan and hands it to Faiz. After inserting the Mission Memory, the boom box converts into two cannons which Faiz uses to finish off the Orphenochs. Smart Lady begs to be with the winning side as they did the closing number without her. In the end, it turns out that the whole ordeal was nothing more than a dream.

Paradise Lost

In the film, Kiba was the primary user of the Orga Gear. In the events of the film, Yuji Kiba is brainwashed by the Smart Brain corporation and is 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 Slash Extreme 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

Rider War

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. They were presumably restored after the destruction (and subsequent revival) of Decade at the end of the Rider War and the worlds were restored. The Destroyer of Worlds

Episode Yellow: Treasure de End Pirates

AR Gekijyouban

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).

Kamen Rider Taisen


Kiba appears as the Horse Orphnoch in a flashback fighting Kaixa while Faiz fought the Arch Orphnoch in a Takumi's flashback in Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai. Kusaka died after being defeated by the Horse Orphnoch.

Kiba is a close to polar opposite of Takumi. While Takumi is aloof and actually prefer to be alone and rude, Kiba is friendly and polite. Being an Orphnoch didn't change his personality much, like Takumi. Initially had a great hatred to Takumi but only as Faiz because he thought that Faiz is a being that will destroy all Orphnoch coldly, he would later become the most trusted friend to Takumi, so does he.

However, Kiba is not a man without flaws. As Kiba would kill humans if they vexed his heart deeply, such as killing his ex-girlfriend and his cousin, who stole his girlfriend, because they loathed him badly and would later killed special police force for torturing Yuka (which had been done on the killing by a Lucky Clover). He would even dare to throw his humanity, shall he lost faith on it, the very different thing which not even Takumi will do.


Fight Form

Horse Orphnoch


  • Height: 210 cm.[1]
  • Weight: 137 kg.[1]


  • Hearing: 5 km.[2]

Fight Form (格闘態 Kakutō-tai) is the main form of Horse Orphnoch, carrying a sword named simply "Horse Sword" (ホースソード Hōsu Sōdo). He is an extremely powerful Orphnoch, at least as strong as members of the Lucky Clover group, if not more so.

Dash Form

Dash Form


  • Height: 365 cm.[1]
  • Weight: 510 kg.[1]

Ability Parameters:

  • Maximum Jump Height: 30 m.[1]
  • Maximum Running Speed: 360 km/h.[1] (100 m. per 1 sec.)

Fight Form is able to assume a centaur-like Dash Form (疾走態 Shissō-tai)

Violent Emotion

Violent Emotion


  • Height: 220 cm.[3]
  • Weight: 147 kg.[3]

Ability Parameters:

  • Punching Power: 3 t.[3]
  • Maximum Jump Height: 70 m.[3] (35 m. with one leg[3])
  • Maximum Running Speed: 350 km/h.[3] (approx. 100 m. per 1 sec.)

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. Gone is the hoof design on its chest and replaced by a larger and more powerful chest armor. During the last episode of the TV series, Horse Orphnoch evolved into the film version during his final battle with Faiz Blaster Form, but reverted back to his regular TV version prior to his demise.

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 bad enough for Faiz to finish it off.

Rider Statistics

  • Rider Height: 202 cm.[4]
  • Rider Weight: 101 kg.[4]

Ability Parameters:

  • Punching Power: 4.5 t.[4]
  • Kicking Power: 9 t.[4]

  • Maximum Running Speed: 100 m. per 5.6 sec.[4]

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 Beast Orphnoch and the Orga Gear self-destructed.

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.

Kamen Rider Faiz

―Transformation announcement[src]
  • Rider Height: 186 cm.[5]
  • Rider Weight: 91 kg.[5]

Rider Senses:

  • Hearing: 5 km.[2]

Ability Parameters:

  • Punching Power: 2.5 t.[5]
  • Kicking Power: 5 t.[5]
  • Maximum Jump Height: 35 m.[5]
  • Maximum Running Speed: 100 m. per 5.8 sec.[5]

Special Attacks:

When Takumi was revealed to be the Wolf Orphnoch and declared himself unworthy of the title, he asked Kiba to become Kamen Rider Faiz in his place.

Once transformation is completed, the Faiz Armor has several key features in its design to offer protection to the user. Like all Rider gears, the Faiz armor manifests when the Faiz Driver generates Photon Blood, a glowing substance generates the soft Sol Foam suit, Sol Metal armor, and Fullmetal Lung chest armor via traveling through the red Photon Streams that ends at the Photon Terminals at the gauntlets and Power Anklet greaves, the right Anklet having a Energy Holster that the Faiz Pointer can be connected to. The helmet is unique due to its Global Feeler antenna to link up to Smart Brain's networks and Ultimate Finder visor that gives Faiz incredible vision to see in darkness, giving the illusion of a glowing eye, and a limited amount of x-ray vision.

Rider Statistics

  • Rider Height: 186 cm.[7]
  • Rider Weight: 91 kg.[7]

Ability Parameters:

  • Punching Power: 3.75 t.[7]
  • Kicking Power: 7.5 t.[7]
  • Maximum Jump Height: 52.5 m.[7]
  • Maximum Running Speed: 100 m. per 0.0058 sec.[7]

Special Attacks:

  • Grand Impact: 7.8 t.[7]
  • Strengthened Crimson Smash: 25.5 t.[7]

Axel Form (アクセルフォーム Akuseru Fōmu) is a form where Faiz can now move at the speed of sound for usually 10 seconds, his physical attacks also becomes 1.5 times stronger and he can perform a new variety of his regular finishing techniques.

The wearer must be in Faiz’s basic form to transform, with the Faiz Axel watch attached, transferring the Axel Memory from it to the Faiz Driver. When this is complete, the Full Metal Lung chest plates will rise out of their recesses and rotate from the scapula to form shoulder pads and reveal the Faiz Core in the center of the chest.

The Sol Foam remains black, while the Photon Streams turn silver and the Ultimate Finder turns red and "Start Up" begins. Once Faiz has reverted after "Time Out", the Mission Memory keys are returned to their respective holders. The transformation usually fatigues Faiz and has never been done 2 times in the same scene. This ability was used mainly by Takumi, the suit's predominant user, though Yuji used it once when he took over temporarily as Faiz.

After losing his love for humans and deciding he was purely an Orphnoch, Kiba killed Kusaka and took the Kaixa Gear, fighting for Smart Brain, and, by extension, against Faiz and Delta. However, after losing to Takumi, he used the Kaixa Gear to help him defeat the Orphnoch King.

Once transformation is completed, the Kaixa Armor has several key features in its design to protect protection to the user. Like all gear, the Kaixa armor manifests when the Kaixa Driver generates Photon Blood, a glowing substance generates the soft Sol Foam suit, Sol Metal armor, and Fullmetal Lung chest armor via traveling through the two yellow Photon Streams lines that gives Kaixa greater strength at the cost of speed. The steams end at the Photon Terminals at the gauntlets and Power Anklet greaves, the right Anklet having a Energy Holster that the Kaixa Pointer can be connected it. The helmet is unique due to its Global Feeler antenna to link up to Smart Brain's networks and the X Finder visor that gives Kaixa incredible vision to see in darkness, giving the illusion of a glowing eye, and a limited amount of x-ray vision.
