(Redirected from Kamen Rider Ouja)

Kamen Rider Ryuki (仮面ライダー龍騎, Kamen Raidā Ryūki) is a Japanese tokusatsu series that serves as the 12th installment in the Kamen Rider franchise and the third entry in the Heisei era. The series follows idealist journalist Shinji Kido as he attempts to stop the violent Rider War from claiming more innocent lives than it already has.

Main characters[edit]

Shinji Kido[edit]

Shinji Kido (城戸 真司, Kido Shinji) is a kind-hearted, friendly, simple, and naive idealist who works at the ORE Journal as a journalist trainee until he finds one of Shiro Kanzaki's Card Decks, encounters the Chinese dragon-like Mirror Monster Dragreder (ドラグレッダー, Doragureddā), and stumbles into the Mirror World while investigating Koichi Sakakibara's disappearance. Despite being told to stay out of the Rider War by Ren Akiyama, Shinji chooses to join anyway to stop the other Mirror Monsters from devouring people and stop the Rider War, forming a contract with Dragreder and becoming Kamen Rider Ryuki in the process. By the series finale, he dies protecting civilians from a pack of Mirror Monsters, but Shiro reverses the Rider War's events, resurrecting its participants and allowing them to resume their normal lives.[1][2][3][4]

While transformed, Shinji is equipped with the Drag Visor (ドラグバイザー, Doragu Baizā) gauntlet, which allows him to summon Dragreder, the Drag Saber (ドラグセイバー, Doragu Seibā), the Drag Claw (ドラグクロー, Doragu Kurō) gauntlet, and the twin Drag Shields (ドラグシールド, Doragu Shīrudo) as well as perform the Dragon Rider Kick (ドラゴンライダーキック, Doragon Raidā Kikku) finisher with the appropriate Advent Cards. With the Survive Rekka (サバイブ烈火, Sabaibu Rekka, Survive Raging Fire) card, he can transform further into his ultimate form, Kamen Rider Ryuki Survive (仮面ライダー龍騎サバイブ, Kamen Raidā Ryūki Sabaibu), and evolve Dragreder into Dragranzer (ドラグランザー, Doraguranzā), giving it the ability to transform into a motorcycle. In this form, he wields the Drag Visor Zwei (ドラグバイザーツバイ, Doragu Baizā Tsubai) firearm, which can convert into the Drag Blade (ドラグブレード, Doragu Burēdo) sword and allow him to perform the Dragon Fire Storm (ドラゴンファイヤーストーム, Doragon Faiyā Sutōmu) finisher alongside Dragranzer.

Shinji Kido is portrayed by Takamasa Suga (須賀 貴匡, Suga Takamasa).

Ren Akiyama[edit]

Ren Akiyama (秋山 蓮, Akiyama Ren) is a cold loner who fights constantly and is frequently unemployed. Sometime prior to the series, he joined Shiro Kanzaki's Rider War to revive his fiancé, Eri Ogawa, who fell into a coma following an encounter with the bat-like Mirror Monster Darkwing (ダークウイング, Dākuuingu), who he formed a contract with to become Kamen Rider Knight (仮面ライダーナイト, Kamen Raidā Naito). Despite initial reluctance, he befriends Shinji Kido and fights alongside him to stop Mirror Monsters and malicious Rider War competitors until Shinji gives his life saving civilians. Ultimately, Ren faces the last participant, Kamen Rider Odin, in combat until Shiro's sister Yui dies, causing Odin to fade away. Despite becoming the winner by default, Shiro reverses the Rider War, leading to Ren becoming a full-time employee at the Atori coffee shop while Eri is revived in the new timeline.

While transformed, Ren wields the Dark Visor (ダークバイザー, Dāku Baizā) rapier, which allows him to summon Darkwing, the Wing Lancer (ウイングランサー, Uingu Ransā) lance, and illusionary copies of himself as well as perform the Flying Lancer (飛翔斬, Hishōzan) finisher with the appropriate Advent Cards. On its own, Darkwing can mount itself on Knight's back to form the cape-like Wing Wall (ウイングウォール, Uingu Uōru) shield and perform the Dark Tornado (ダークトーネードー, Dāku Tōnēdō) and Sonic Breaker (ソニックブレイカー, Sonikku Bureikā) attacks. With the Survive Shippu (サバイブ疾風, Saibabu Shippū, Survive Hurricane) card, Ren can transform into his ultimate form, Kamen Rider Knight Survive (仮面ライダーナイトサバイブ, Kamen Raidā Naito Sabaibu), and evolve Darkwing into Darkraider (ダークレイダー, Dākureidā), granting it the ability to transform into a motorcycle.[1][2][4] In this form, he possesses the left arm-mounted Dark Visor Zwei (ダークバイザーツバイ, Dāku Baizā Tsubai) scabbard, which can either separate into the Dark Blade (ダークブレード, Dāku Burēdo) sword and the Dark Shield (ダークシールド, Dāku Shīrudo) or convert into the Dark Arrow (ダークアロー, Dāku Arō) crossbow and allow him to perform the Hurricane Edge (疾風断, Shippūdan) finisher alongside Darkraider.

Ren Akiyama is portrayed by Satoshi Matsuda (松田 悟志, Matsuda Satoshi).

Yui Kanzaki[edit]

Yui Kanzaki (神崎 優衣, Kanzaki Yui) is a young caring woman who had been aiding Ren prior to the series to locate her long-lost brother Shiro Kanzaki.[1] While investigating Shiro's disappearance over the course of the series, she discovers the drawings they made as children served as the basis for the Mirror World's monsters and that, due to their neglectful parents, the real Yui died and allowed her Mirror World counterpart to inhabit her body. Due to being unable to survive outside of the Mirror World, the doppelganger will die on Yui's twentieth birthday, which led to Shiro developing the Rider War in the hopes of saving her. Having repressed these memories, Yui remains unaware of them until the present. Despite Shiro, Ren, and Shinji Kido's best efforts, the Mirror World Yui fades from existence short of the deadline, though her spirit appears before Shiro to tell him she did not want him to save her in the manner he wanted, inspiring him to reverse the Rider War's events.

In an alternate ending depicted in the film Kamen Rider Ryuki: Episode Final, the lonely Yui had met and befriended Shinji as children, but he seemingly abandoned her despite promising not to. Yui was invited by her Mirror World counterpart to play with her, only to learn she will immediately die if she returns to the real world. Yui's doppelganger loaned the original her lifespan, which will last until her twentieth birthday, in exchange for Yui and Shiro's drawings. After joining Ren and Shinji in their fight against the Mirror Monsters in the present, Yui eventually dies, though an angered Shiro does not end the Rider War.

Yui Kanzaki is portrayed by Ayano Sugiyama (杉山 彩乃, Sugiyama Ayano).

Shiro Kanzaki[edit]

Shiro Kanzaki (神崎 士郎, Kanzaki Shirō) is a mysterious scientific genius and Yui's older brother who was taken to live with relatives in America thirteen years prior to the series. He conducted research into the Mirror World (ミラーワールド, Mirā Wārudo), a parallel dimension opposite to the real world, before he disappeared and was presumed dead. In reality, he merged with his Mirror World counterpart to survive in the Mirror World. In the intervening years, he developed chronokinesis and created thirteen Card Decks (カードデッキ, Kādo Dekki), each with their own set of Advent Cards (アドベントカード, Adobento Kādo), V-Buckle (Vバックル, Bui Bakuru) belts, and Visor (バイザー, Baisā) card readers to establish the Rider War in the hopes of averting Yui's death, which is said to take place on her twentieth birthday, by promising to grant the winner one wish in exchange for killing their fellow competitors. By the series finale, Shiro allows Yui to die and honors her dying wish of reversing time to avert the Rider War.[1][2][3][4]

Shiro developed the Card Decks and Advent Cards to allow the 13 Kamen Riders (13人の仮面ライダー, Jūsan-nin no Kamen Raidā) to survive in the Mirror World by forming contracts with and draw energy from their Contract Monsters (契約モンスター, Keiyaku Monsutā) in return for feeding them the life forces of the Mirror Monsters they destroy.

Shiro Kanzaki is portrayed by Kenzaburo Kikuchi (菊地 謙三郎, Kikuchi Kenzaburō).

Kamen Rider Zolda[edit]

Kamen Rider Zolda (仮面ライダーゾルダ, Kamen Raidā Zoruda) is a Rider moniker specialized in long-range combat aided by the robotic Minotaur-like Contract Monster Magnugiga (マグナギガ, Magunagiga).

While transformed, the user wields the Magnu Visor (マグナバイザー, Maguna Baizā) submachine gun, which allows them to summon Magnugiga, the back-mounted Giga Cannons (ギガキャノン, Giga Kyanon), the Giga Launcher (ギガランチャー, Giga Ranchā) missile launcher, and the Giga Armor (ギガアーマー, Giga Aāmā) shield as well as perform the End Of World (エンドオブワールド, Endo Obu Wārudo) finisher alongside Magnugiga with the appropriate Advent Cards.

Shuichi Kitaoka[edit]

Shuichi Kitaoka (北岡 秀一, Kitaoka Shūichi) is a self-proclaimed "super-lawyer" who tends to only help someone if he has something to gain from them and was diagnosed with terminal cancer. With months left to live, he joins Shiro Kanzaki's Rider War as Kamen Rider Zolda with the hopes of achieving immortality and continuing his extravagant lifestyle. However, his condition leaves him vulnerable to fainting spells and dizziness, which eventually forces him to ask his secretary and bodyguard, Goro Yura, to take his place as Zolda during the Rider War's final stages.[1][2][3][4]

In an alternate ending depicted in the film Kamen Rider Ryuki: Episode Final, Kitaoka forfeits the Rider War due to his declining health.

During the events of the crossover film Kamen Rider × Super Sentai: Ultra Super Hero Taisen, the Game World version of Kitaoka transforms into the green-colored Midorider (ミドライダー, Midoraidā), a hybrid of Midorenger and the Double Riders. In this form, he commands the Gokaigers' Gokai Galleon.

Goro Yura[edit]

Goro Yura (由良 吾郎, Yura Gorō) is Kitaoka's loyal secretary, bodyguard, and a former client of his who is highly skilled with household work and hand-to-hand combat. Aware of Kitaoka's activities as Kamen Rider Zolda, Goro assists him as much as possible.

Goro Yura is portrayed by Tomohisa Yuge (弓削 智久, Yuge Tomohisa).

Takeshi Asakura[edit]

Takeshi Asakura (浅倉 威, Asakura Takeshi) is a sadistic, cruel, bloodthirsty, arrogant, and bad-tempered criminal with a reputation for loving the act of fighting and killing during his fits of rage after he murdered his entire family as a child. After being represented by Shuichi Kitaoka, who ensured Asakura would remain in prison, the latter joined Shiro Kanzaki's Rider War to satisfy his destructive nature and formed a contract with the giant cobra-like Mirror Monster Venosnaker (ベノスネーカー, Benosunēkā), becoming Kamen Rider Ouja (仮面ライダー王蛇, Kamen Raidā Ōja). With his newfound powers, Asakura breaks out of jail to seek revenge on Kitaoka upon learning of the latter's participation in the Rider War. After receiving Ren Akiyama's help in faking his death to stop the police from interfering with his activities, Asakura kills Kamen Riders Raia and Gai and takes their Contract Monsters as his own. However, the police eventually learn the truth, forcing Asakura to settle his grudge against Kitaoka in a final battle, only to learn his opponent had switched places with Goro Yura, leaving the criminal in disarray over being denied the thing he wanted most before the police kill him. After Shiro reverses the Rider War, revives the participants, and erases their memories of it, Asakura escapes from prison and goes into hiding.[1][2][3]

Years later, during the events of the web-exclusive series Kamen Rider Outsiders, Asakura became a hired thug for a corrupt politician before he was betrayed and accepts Kamen Rider Odin's offer to participate in a new Rider Fight to evade arrest, which restores his memories in the process. Asakura subsequently kills his former employer and wins the Rider Fight before learning of Zein from Kamen Rider Diend and developing an interest in the former.

In an alternate ending depicted in the film Kamen Rider Ryuki: Episode Final, Asakura battles Kamen Rider Femme, who seeks revenge on him for her older sister's murder, before he loses Genocider to Kamen Rider Ryuga and Femme destroys his Card Deck, leaving Asakura to dissolve in the Mirror World. In the web-exclusive special Kamen Rider Brave: Survive! The Revived Beast Rider Squad, Foundation X revives this version of Asakura in an artificial body.

While transformed, Asakura wields the Veno Visor (ベノバイザー, Beno Baizā) scepter, which allows him to summon Venosnaker and the Veno Saber (ベノサーベル, Beno Sāberu) as well as perform the Veno Crash (ベノクラッシュ, Beno Kurasshu) finisher alongside Venosnaker with the appropriate Advent Cards. After killing Raia and Gai, Asakura can use their Advent Cards, fuse their respective Contract Monsters Evildiver and Metalgelas with Venosnaker to create the chimeric Contract Monster Genocider (ジェノサイダー, Jenosaidā), and perform the Doomsday (ドゥームズデイ, Dūmuzudei) finisher alongside it. In Kamen Rider Outsiders, Asakura uses Kamen Rider Odin's Survive Mugen card to transform into his ultimate form, Kamen Rider Ouja Survive (仮面ライダー王蛇サバイブ, Kamen Raidā Ōja Sabaibu), and evolve Venosnaker into a stronger form, granting it the ability to transform into a motorcycle. In this form, he wields the Veno Visor Zwei (ベノバイザーツバイ, Beno Baizā Tsubai) firearm, which resembles Ryuki Survive's Drag Visor Zwei.

Following a failed attempt at taking over the ORE Journal and serving jail time before his father and Shuichi Kitaoka bail him out, Shibaura learns Kamen Riders Ryuki, Knight, and Raia's identities and invites them to a party in the hopes of killing them.

Throughout the Rider War, Odin makes brief appearances to fight the other Kamen Riders until he and Knight are left. Following a climactic battle, Odin disappears after Shiro sees the pointlessness of the Rider War upon Yui's death.[1][4]

Years later, during the events of the web series Rider Time: Kamen Rider Ryuki, Odin resurfaced in a new host to commence a new Rider War through Tatsuya Kanō and his grievously injured girlfriend Sara in an attempt to revive Yui. Once Tatsuya is defeated by Kamen Rider Zi-O, Odin makes his presence known while using the Survive cards to overpower him and Kamen Rider Geiz before they use the Ryuki and Knight Ride Watches to negate his invincibility and defeat him and Zi-O negates the events.

After joining the Rider War, forming a contract with the anthropomorphic white tiger-like Mirror Monster Destwilder (デストワイルダー, Desutowairudā), and becoming Kamen Rider Tiger (仮面ライダータイガ, Kamen Raidā Taiga), Tojo initially aids his teacher Hideyuki Kagawa in closing the Mirror World before killing him in a twisted attempt at vindicating Kagawa's ideals about heroism. However, Tojo fell into a downward spiral of contradictions throughout the Rider War until he witnesses a father and son, who reminded Tojo of Kagawa and his own child, and sacrifices himself to save them from a vehicular accident. The next day, the newspaper would run the story of Tojo's deed, labeling him a hero.[4] After Shiro reverses the Rider War's events, Tojo is revived with no memory of it.

As a result, he joined the Rider War, formed a contract with an anthropomorphic gazelle-like Mirror Monster subspecies called Gigazelles (ギガゼール, Gigazēru), and became Kamen Rider Imperer (仮面ライダーインペラー, Kamen Raidā Inperā) to live a rich and happy life. To achieve his goal, he becomes a mercenary, attempting to sell his strength to his fellow competitors. After attaining his father's inheritance and losing his reason to fight however, Sano discovers he cannot back out of the Rider War and attempts to buy the other Riders' services in the hopes that they will fight for him.

While transformed, Takamizawa is equipped with the left thigh-mounted Bio Visor (バイオバイザー, Baio Baizā), which allows him to summon Biogreeza, the Bio Winder (バイオワインダー, Baio Waindā) yo-yo, turn invisible, assume other Riders' forms and weapons, and perform the Death Punish (デスパニッシュ, Desu Panisshu) finisher alongside Biogreeza with the appropriate Advent Cards.

Itsuro Takamizawa is portrayed by Arthur Kuroda (黒田 アーサー, Kuroda Āsā).
