Icon-zi-o.png This article is about a/an rider in Kamen Rider Zi-O.

In 2002, Takeshi Asakura (浅倉 威 Asakura Takeshi) was Kamen Rider Ouja (仮面ライダー王蛇 Kamen Raidā Ōja, lit. "King Snake"). Seventeen years later, a new Rider Fight begins and Takeshi returns as Ouja once more.


Rider Time Ryuki

Advent Again

Takeshi Asakura was among 13 people mysteriously kidnapped into the Mirror World and forced to join a survival battle royale. Unlike the other ones, he still kept his memories and quickly transformed into Kamen Rider Ouja.

On the 4th day, he confronted Kamen Rider Knight, who he claimed to be his archenemy. During their fight, Ouja was ambushed by a monster but it was intercepted by Kamen Rider Zolda. As Knight engaged the monster, Ouja confronted the newly appeared Rider, but Zolda quickly detransformed, revealing himself to be Goro Yura. Realizing him to be the lackey of Shuichi Kitaoka, Takeshi took his leave, but Yura insisted to follow him as a servant, even when Takeshi violently beat him. Later, Takeshi accepted Yura as his servant and had him prepare a meal for him. Appealled by Yura's cooking skill, Takeshi promised that he would spare Yura for the time being.

On the 5th day, when Shinji Kido's group was betrayed by Kamen Rider Raia and attacked by Scissors, Gai and Tiger, Ouja suddenly appeared and used a Final Vent kick to murder Tiger. When Ouja tried to strike a helpless Shinji Kido, he was intercepted by Kamen Rider Knight. Advent Again.

Another Alternative

As Knight blocked the strike, Ouja joined the battle with Gai and Scissors. Zolda activated his Final Vent, causing a huge explosion, with Ouja laughing right beside him.

On the 6th day, Takeshi was seen eating some food prepared by Goro. He was pleased at the food as usual, but he still could not understand why Goro was serving him, as Takeshi was Shuichi's enemy. He thought that Shuichi may "turn in his grave" should he know Goro was his servant. Takeshi admitted he had never actually hated Shuichi, but it was Shuichi who hated him. He then remarked that "hatred is a thing that you can trust".

As Takeshi was the seemingly only participant with memory still intact, Ren and Shinji came to his place to ask him about the past. Takeshi's only response was that their past was fighting and killing each other, and they were destined to keep fighting and killing like that for eternity.

Some time later, an outraged Ouja was looking for Ren and Shinji, telling them to come out and entertain him more. Ouja started to strike random objects in a fit of rage, but the two Riders were still nowhere to be found. A vexed Takeshi later vented his anger on Goro due to having nobody to fight with. He threatened to kill Goro if Goro did not find an opponent for him right away. Just at that moment, Dark Shinji came and offered to "play" with Takeshi. Finally happy with a chance to fight, Takeshi transformed and charged at Dark Shinji. The two fought a brief while before Knight appeared and attacked Ouja, remarking that Kido's opponent was not the madman but him. Ouja was amused, and began fighting Knight. Knight told Ouja that he was merely wanting to die, then used his Final Vent on him right after, fatally wounding Ouja, forcing him to flee. 

As Goro found his "master" on the verge of death due to the attack, he used the Magnuvisor in human form to shoot at Ouja. It was revealed here that Goro's memory about the past was also intact like Takeshi, and that he only agreed to serve and follow Takeshi earlier so that he may have a chance to kill him. He had been loyal to Shuichi Kitaoka all along, and he wanted to fulfill his late master's wishes to end Takeshi once and for all. Goro transformed into Zolda and used his Shoot Vent to attack Ouja, wounding him even more. Engulfed in flames, Ouja still defiantly charged at Zolda and used his Veno Saber to stab him in the chest. The two combatants were subsequently forced out of their transformations. Takeshi was on the ground unconscious. Goro, thinking that he had fulfilled his master's wish, started to disintegrate because of Ouja's inflicted stab wound.

Alive A Life

"NOT YET! More... More..."
―Takeshi's last words before he disintegrated, still wanting to fight even more.[src]

However, Takeshi was revealed to be alive. He grabbed his Veno Saber in his human form to fight Shinji and Ren. As he was about to kill Shinji, Ren shielded him from the attack and received a mortal wound from Takeshi as a result. Takeshi, still wanting to fight and kill more and more, screamed in dissatisfaction as he disintegrated.

After Sougo resets the timeline, his fate is left unknown, but it's presumed that his death was reversed just like the others. 2019: Apocalypse

Special Attacks:

Takeshi 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.

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.
