Takeshi Asakura (浅倉 威 Asakura Takeshi) is one of the participants of the Rider Fight known as Kamen Rider Ouja (仮面ライダー王蛇 Kamen Raidā Ōja, lit. "King Snake").


Kamen Rider Ryuki: Episode Final

Ouja is stabbed by Femme

Asakura's death

Asakura was targeted by Miho Kirishima, who became Kamen Rider Femme to hunt him down for revenge. Though she was outmatched by the stronger opponent, Kamen Rider Ryuga's destroying of Genocider reverted Ouja to Blank Form. Weakened, Femme stabbed right at Ouja's blank deck, destroying it. Shortly, Ouja's armor disintegrated and Asakura dissolved in the Mirror World as he attempted to take Miho down with him.

"Fight! Keep fighting! If you don't fight...you will die..."
―Asakura's last words before fading away once again[src]

Asakura was later revived along with the Beast Rider Squad as part of Foundation X's scheme in researching the Rider Gashats. He attacks Hiiro Kagami's nurse assistants, Mizuki and Satsuki, as well as Emu Hojo. Asakura as Ouja would later be defeated by Brave's Level 4 form, leading to Asakura fading away once again.

Special Attacks:

Asakura can transform into Kamen Rider Ouja using his Advent 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 Veno Saber (ベノサーベル Beno Sāberu), a sword derived from Venosnaker's tail.

Asakura 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 Evil Whip (エビルウィップ Ebiru Wippu), a whip derived from Evildiver's tail, and Gai's Metal Horn (メタルホーン Metaru Hōn), a gauntlet derived from Metalgelas' head. Ouja is also able to perform the Riders' respective finishers.

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 Metal Horn if he does not already possess it. Ouja next grabs onto Metalgelas' head with his legs and points the Metal Horn in front of him. Metalgelas then runs into the enemy, resulting in Ouja striking it with the Metal Horn.

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: 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.

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).


  • It is strongly implied the version of Takeshi Asakura in Kamen Rider Brave: ~Let's Survive! Revival of the Beast Rider Squad!~ is the version from Episode Final since Asakura mentioned his revival as being recent, ignoring the time reset in Ryuki's series' finale and him referencing a certain girl in the special as well.
  • Strangely, Ouja's Blank Form does not lose the Snake motifs as Ryuki's loses his Dragon motifs upon reverting to Blank Form. Ouja's Blank Form instead is his standard form desaturated to gray tones.
