"Being a Rider really is fun..."
―Takeshi on his involvement in the Rider Battle.[src]

Takeshi Asakura (浅倉 威, Asakura Takeshi) is Kamen Rider Ouja (仮面ライダー王蛇, Kamen Raidā Ōja, lit. "King Snake"), a Rider in the Kamen Rider Series Kamen Rider Ryuki. He is the sixth of the 13 Kamen Riders the story revolves around and serves as one of the main villains in the series.



Takeshi was born in April 10, 1977. In 1990. At age 13, he murdered both of his parents in an act of arson, although his younger brother survived. Since, Takeshi developed a reputation as a sadistic felon with a love for fighting, maiming, and otherwise destroying anything in his random fits of rage. As a result of his sadistic nature, prior to becoming a Rider, Takeshi was personally responsible for ending the piano career of Miyuki Tezuka's friend Yuichi Saito. Eventually, his arrogant personality results with his defense attorney, Shuichi Kitaoka, refusing to represent him and left him to continue to serve jail time. Because Takeshi was in prison and could not feed his destructive nature, he gladly accepted Shiro's offer to join the Rider War and forms a pact with Venosnaker, using his newfound powers as Kamen Rider Ouja in its many forms to break out of jail, avoid the law, and get his revenge on Shuichi.

Ouja and his Mirror Monsters.

Ouja fought only for the sake of fighting and was the first Rider to kill other Riders, killing Kamen Rider Gai and Kamen Rider Raia and taking their Contract Monster afterwards. Ouja also destroyed Kamen Rider Imperer's deck, causing him to die in the Mirror World. While the other Riders had a desire that would be granted if they won the Rider War, Takeshi was simply having fun, and said that if he won, he would wish for the Rider War to start over so he could keep enjoying himself.

Ren helped Takeshi fake his death once so he can fight in the Rider War without police interference. However, when he was publicly revealed to be alive, Takeshi was soon later captured, going in and out of jail for several instances. In one such case, he uses Metalgelas while in a police van to dispose of his police captors before escaping into the Mirror World. After a fight with Kamen Rider Ryuki Survive and Kamen Rider Tiger, he had been seriously injured and handed back to the authorities once again by Shinji. Soon he escaped again, with aid of his lawyer at that time whom he had knocked out and switched clothes with the lawyer to escape.

In the process of learning of Shuichi's identity as a Rider, Takeshi attempted to lure him by staging a hostage situation to get Shuichi. Takeshi had Venosnaker kidnap Goro Yura so Ouja can pressure Zolda into bringing Knight, Ryuki and Raia to a specific meeting place. However, Goro escapes by picking the lock of the handcuffs. Though he lost to Zolda, Ouja survived and senselessly killed Kamen Rider Gai in the process.

Upon learning of Shuichi's identity as a Rider, he formed a personal grudge against him that manifested in many attempts to harm Shuichi. The two would fight many times throughout the series. Miyuki Tezuka (Kamen Rider Raia) also held a personal grudge against Takeshi for ending the piano career of his friend, Yuichi Saito.

During the series, he came under fire from his three monsters when they were hungry for life energy. They came close to devouring Takeshi if not for his strong determination. After hunting down three Mirror Monsters, Ouja was able to feed his contract monsters. Kamen Rider Knight and Zolda tried to prevent his monsters from feeding so that they would turn on him and remove Takeshi from the Rider War. but Kamen Rider Ryuki intervened and allowed the monsters to feed because Takeshi had actually saved a small girl from the three monsters they hunted.


At the end of the series he finally has his showdown with Zolda. Ouja, using his "Doomsday" Final Vent, destroys Magnugiga before fatally injuring Zolda. Though happy with his victory, Ouja finds out seconds later that "Zolda" was actually Goro, as Shuichi gave him his vent deck prior to succumbing to his cancer during the fight. Just as he returned to the real world in utter disarray of being denied the right to kill the man he hated the most, Takeshi finds himself surrounded by the authorities in the warehouse he was in with snipers covering them. Defiant to the end, Takeshi grabs a metal rod and runs at the cops screaming as they gun him down, brought to justice at last.

However, because Shirou restored time to its proper course after Yui's death, Takeshi was given a second chance in life with no memory of being a Rider and keeping a low profile, but still having a rude personality, as he was kicking Shinji's bike because it was in the way.

They apologize for being late; when Ryuki accuses Ouja of being a villain, they all claim that as Kamen Riders they are the protectors of humanity, all completely out of character. They rush in to keep fighting the Monsters as Ryuki stands in confusion, but he eventually joins in. As they fight the monsters down, explosions knock them all back, and the mysterious figure appears, named by Knight as Kamen Rider Agito, and by Zolda as the ruler of the "Miracle World". Burning Agito attacks them with fire before a gold figure jumps in, introducing himself as the real Kamen Rider Agito, saying Burning Form is a Miracle World illusion. The five Riders strike a pose and rush forward to fight the Fake Agito and his Mirror Monsters. the real Agito appears in Ground Form and teams up with Kamen Rider Ryuki, who imitates Agito's Rider Kick to destroy the imposter. In the end, this is revealed to be Shinji's dream.

"I'm vexed..."
―Takeshi whenever he is frustrated.[src]

Takeshi is a violent, bad-tempered, murderous, and sadistic man, finding joy in fighting, maiming, killing, or otherwise destroying anything in his random fits of rage. He is actually so drawn to violence that he feels an unbearable tension which can only be eased through fighting. He has no sympathy or remorse for his actions, and will attack anyone simply because he is "vexed". In fact, when he's "vexed", he would even go as far as to hurt himself, just to ease his tension. This is shown when he is confined in a jail cell, he becomes so frustrated that he begins banging his head on the wall until he draws blood.

His unhinged nature is such that he kills his entire family without any sign of repentance in a fire when he's only 13 years old. Furthermore, upon finding out his brother survives the event, he tracks him down only to feed him to Venosnaker. In fact, Takeshi's wild personality even allows him to tame his three Mirror Monsters (two of which previously belong to the Riders he has killed). Takeshi alone racks up the highest body count of all the Riders in Kamen Rider Ryuki, being directly responsible for the deaths of Gai, Raia, Imperer and Zolda.

His love for fighting is so much it is all it takes for him to join the Rider War. Unlike other Riders who join in order to have their wishes fulfilled, Takeshi is just simply having fun with killing and fighting. In fact, he does not even know there is a "wish" for the winner until near the end-game stages of the War. Even upon learning that fact, he only states his wish is to make the Rider War endless, so that he can continue his destructive routine more and more to feed his urge for violence. However, Takeshi does not always go for the kill if he thinks it is not fun, as he always wants to transform and fight rather than fight in human form. On occassions, he has actually talked with Shuichi right inside his office without fighting him. He even refuses to face Shinji when he is broken, pushing him off and declaring that the Shinji who is not being himself is not the Shinji he wants to fight and kill. However, these sentiments only apply for the 13 Riders. Takeshi has no qualms killing commoners in cold blood without transforming without a moment's hesitation.

Despite his mad and deranged personality, Takeshi is far from being mindless. He is perfectly capable of intelligent manipulation and does not make stupid decisions. This is shown when he uses Gai as a human shield, then kills him in cold blood right after he has served his purpose. He is even perfectly willing to use a young girl as a bait for three Mirror Monsters for his own benefit, and when he does not need her anymore, he leaves her without a word.

Takeshi's utter disragard for human life, the versatility of his Card Deck, along with his murderous and manipulative tendencies make him one of (if not the most) suitable candidates chosen by Shiro Kanzaki for the Rider War.

Fighting Style

Ouja is a melee based Rider like the majority of the Kamen Riders. However, he is extremely sadistic, showing no mercy as well as superior tactics over his opponents. He fights relentlessly, but only if he is sure he will win, and isn't hesitant to use other Riders as factors or pawns, and is even willing to play dirty before fights in his battles. The Sword Vent is his most frequently used weapon. He becomes even more powerful when he forms Contracts with Metalgelas and Evildiver. This grants him access to Gai's Strike Vent and Raia's Swing Vent, making him a more versatile as well as a more deadly force. His Contract Monster Venosnaker frequently participates in his battles, and is often seen as Dragreder's evil equivalent in the series (this has been replaced by Dragblacker). His durability due his wild nature even allows him to keep on fighting despite already being in a near-death stage and no longer a rider. This is shown when he almost kills Miho despite the fact that she is still in her Rider form. Also, he still endures long enough to kill Ren after being fatally wounded by Flyinglancer and MagnuGigalauncher Shoot Vent.

However, Ouja is not without weaknesses. He's more vulnerable towards long-ranged opponents, his own unstable nature outclasses his fighting potential, he rarely uses his special card Steal Vent (possibly because he is comfortable with his choice of weapon, as well as only using it to disarm Riders, which is an ineffective strategy), and he rarely takes advantage of the more powerful Genocider, using the united Contract Monster as a more menacing or intimidating distraction in the battlefield. This may also prove that the united Contract Monster is difficult to control, but is restrainable.

  • Eyesight: 15 km.[1]
  • Hearing: 15 km.[1]

  • Kicking Power: 20 t.[note 2]
  • Maximum Jump Height: 40 m.[1]
  • Maximum Running Speed: 100 m. per 5 sec.[1]

Special Attacks:

Asekura can transform into Kamen Rider Ouja using his Card Deck and V Buckle upon forming a contract with Venosnaker. His Visor is a scepter named the Venovisor (ベノバイザー, Beno Baizā). Ouja's kicking power and running speed are identical to Ryuki's, while his jump punching power and jump height are slightly higher.

Through the use of his Sword Vent Advent Card, Ouja can arm himself with the Venosaber (ベノサーベル, Beno Sāberu), a sword derived from Venosnaker's tail.

Takeshi later forms additional contracts with Evildiver and Metalgelas after the Riders they were previously contracted to, Raia and Gai, are killed. This enables to to use all of Raia and Gai's Advent Cards. Thus, he is able to arm himself with Raia's Evilwhip (エビルウィップ, Ebiru Wippu), a whip derived from Evildiver's tail, and Gai's Metalhorn (メタルホーン, Metaru Hōn), a gauntlet derived from Metalgelas' head. Ouja is also able to perform the Riders' respective finishers.

This form consists of the following parts:

  • O Signal (Oシグナル, O shigunaru): The yellow gem on the forehead. It is a radar sensor that senses the presence of the enemy.
  • Veno Crown (ベノクラウン, Beno Kuraun): The crown. The emblem maximizes the power of Ouja.
  • Solid Face Shield (ソリッドフェイスシールド, Soriddo Feisu Shīrudo): A face protector made of solid Armetal (アーメタル, Āmetaru).
    • Purple Eye (パープルアイ, Pāpuru Ai): The eyes. They allow Ouja to see enemies up to 15km away. Just like the other riders, they also have infrared vision.
  • Veno Chest (ベノチェスト, Beno Chesuto): The chest armor.
  • Granmail (グランメイル, Guranmeiru): A specially strengthened skin that covers the wearer's body, allowing them to stay in the Mirror World for 9 minutes and 55 seconds. If the transformation is cancelled, the user will lose the ability to fight and become monster food.
    • Zippetto Thread (ジペット・スレッド, Jipetto Sureddo): The ports all over the body. They are remote control devices used to control Volcancer. They are located on the back, the shoulders, wrists, sides of the belt, kneepads and back of the legs.
    • Force Bone (フォース・ボーン, Fōsu Bōn): The lines on the suit. They are control organs that are located on the waist, on both arms, and the back of legs. They distribute the power throughout the body in a well-balanced manner.
  • Veno Knuckle (ベノナックル, Beno Nakkuru): The handguards. They are made of Armetal.
  • Purple Armor (パープルアーマー, Pāpuru Āmā): The shin armor. They are made of strong and lightweight Armetal, and are as tough as diamonds.
  • Leg Purple (レッグパープル, Reggu Pāpuru): The shoes. They provide excellent impact resistance and protection.

By using Venosnaker's Final Vent, Ouja can execute his primary finisher, the Veno Crash (ベノクラッシュ, Beno Kurasshu), in which Ouja runs toward the opponent with Venosnaker slithering behind him before jumping into the air. Venosnaker then spits a stream of venom at Ouja, propelling him into a flying bicycle kick that strikes the enemy. By using Evildiver's Final Vent, Ouja can execute Raia's finisher, Hide Venom (ハイドベノン, Haido Benon), in which he rides on Evildiver's back and rams into the enemy. By using Metalgelas' Final Vent, Ouja can execute Gai's finisher, Heavy Pressure (ヘビープレッシャー, Hebī Puresshā), which equips him with the Metalhorn if he does not already possess it. Ouja next grabs onto Metalgelas' head with his legs and points the Metalhorn in front of him. Metalgelas then runs into the enemy, resulting in Ouja striking it with the Metalhorn.

By using the Unite Vent Advent Card, Ouja can combine Venosnaker, Evildiver, and Metalgelas into Genocider. This grants Ouja another Final Vent, which Ouja uses to perform his strongest finisher, Doomsday (ドゥームズデイ, Dūmuzudei): A hole leading to a void opens on Genociders's chest, creating a vortex that begins sucking surrounding objects into it. Ouja then delivers a corkscrew kick to the opponent, pushing them into the vortex and thus into the void, completing destroying the enemy.

Kamen Riders

  • Shuichi Kitaoka/Zolda: Takeshi's enemy who refuses to be his lawyer until he escapes from jail thanks to Shiro Kanzaki. Throughout the series, he is hellbent on killing Kitaoka, seeing it as one of the main reasons why he entered the War. However, in Rider Time: Ryuki, Takeshi admits he has never really hated Shuichi, but it is Shuichi who always hates him instead.
  • Ren Akiyama/Knight: Ren helps Takeshi escape from the police on one occasion just so that he can fight him without interference. However, when Takeshi crosses the line by injuring Shinji's arm in a fight prior to transforming, Ren fights him to claim Ryuki for himself fairly. In Rider Time: Ryuki, Takeshi states that he and Ren are "so close that they have to kill each other". Takeshi finally manages to kill Ren by impaling him with his Sword Vent, but Ren also fatally wounds him with his Final Vent, which ultimately results in his death.
  • Shinji Kido/Ryuki: At first, Takeshi sees Shinji as a bumbling fool. Nevertheless, after learning his identity as a rider and having fought him twice (with the second time resulted in his nearly losing), he feels vexed of his righteousness yet intrigued and sees him as one of his rivals that he has to kill personally. However, Takeshi fails to do so either in the TV Series or In the Movies. In Rider Time: Ryuki, Takeshi himself disintegrates in front of Shinji before inflicting him any harm.
  • Satoru Tojo/Tiger: After Tiger injures him badly in a sneak attack, which results in his being thrown into jail once more, Takeshi takes it upon himself to eliminate Satoru. In fact, on more than one occasion, Takeshi chooses to fight and kill Tiger first even while in the process of battling his archenemy Kitaoka, emphasizing his hate towards the backstabber.
  • Miho Kirishima/Femme: Takeshi murdered Miho's sister when she was young. She wanted revenge on him.


  • Shiro Kanzaki: Despite his destructive nature and love for fighting, Takeshi is surprisingly civil (and even somewhat friendly) towards Shiro. He even offers him food on two occasions. This is possibly because Shiro is the one who gave him his powers in the first place.

Behind the scenes


Takeshi Asakura is portrayed by Takashi Hagino (萩野 崇, Hagino Takashi). As Kamen Rider Ouja, his suit actor was Jiro Okamoto (岡元 次郎, Okamoto Jirō), his sub was Keizo Yabe (矢部 敬三, Yabe Keizō).


  • Ouja's name is variably written as "Oja", "Ohja", and "Ohjya" in media released by TV Asahi, Toei Company, and Bandai.
    • His Rider name, Ouja, could also literally mean "King Evil" (王邪, Ōja), as he is the long standing evil Kamen Rider in this series.

Dub names

In the Korean dub of Kamen Rider Ryuki entitled Masked Rider Dragon, which aired in South Korea, Kamen Rider Ouja is renamed Masked Rider Viper (가면라이더 바이퍼 Gamyeon Raideo Baipeo).

Concept Art

Kamen Rider Ouja Concept Art


  • Kamen Rider Ouja is also based on the Shocker monster, Cobra Man where both individuals share a dominant purple color.
    • Ouja's Contract Monster, Venosnaker also shared this motif to the point where it can also spit dangerous venoms like the said Shocker monster.
    • A homage to Ouja appears in Kamen Rider Den-O in the form of the Cobra Imagin, who not only shares Ouja's cobra motif but is also voiced by Ouja's actor, Takashi Hagino. As pointed out in the design book Imagin: Say Your Wish..., the Cobra Imagin is designed to resemble Ouja.
  • Ouja was seemingly designed as a foil to Ryuki, with similarities between their Sword Vent weapons and Final Vent finishers, as well as both of their Contract Monsters having similar body types. However, this was subverted by the introduction of Kamen Rider Ryuga, a Rider who is a near-identical copy of Ryuki in terms of appearance, arsenal, as well as abilities.
  • Just like the other Kamen Riders, he died an ironic death: he killed the most Riders in the war, but never the ones he wanted to kill the most: Shinji, Satoru and Shuichi. He originally entered the war to kill Shuichi, but when he finally, technically achieved his goal by killing Zolda (who was, in truth, Goro Yura), he went mad with dissatisfaction and was himself killed by the cops. This was still true in Rider Time: Ryuki, Takeshi still had the highest kill count, but he never managed to kill the ones he wanted to kill.
    • While he has killed the most, he has also died the most deaths among the Kamen Riders in Ryuki: he was killed by the authorities after losing his cool in the TV series, impaled by Femme in Episode Final, defeated by Kamen Rider (Deadheat) Mach's finisher in D-Video Special: Kamen Rider 4, killed by Brave's Level 4 form in the Beast Rider Squad special and lastly succumbed to his injuries after receiving Zolda's Shoot Vent and Knight's Final Vent in Rider Time: Kamen Rider Ryuki.
  • Takeshi claims to have developed omnivorous traits to survive on the streets. He is shown eating raw egg yolks and oyster shells (both in Shuichi's house) without showing any signs of frustration.
  • Gen Urobuchi, the head writer of Kamen Rider Gaim, used Ouja to describe Takatora Kureshima (Kamen Rider Zangetsu), referring to him as 'the Ouja' of the series. Although, it was later revealed that Urobuchi refers to the second Zangetsu, Mitsuzane Kureshima, especially in Gaim's second act.
  • The kanabo he used in Kamen Rider Decade is similar to the one used by Tohki.
  • Takeshi is the only Ryuki Rider that does not have an A.R. World counterpart, at least not seen in the Ryuki arc, and that the Ouja that is summoned by Kiva-la in World of Hibiki and later by Diend in World of Decade is Takeshi himself.
  • In the original series and Specials, Ouja is always left-handed. However, in any of his appearances following Ryuki, save for his sole appearance in Decade, he is right-handed. The reason for this is unknown.
