"Mirrors facing each other create an infinite number of worlds. There is more than one fate. The only thing that's the same is desire. All humans desire. That's why they fight. And when that desire becomes so great that it becomes unbearable, people... become Riders. The Rider battle... begins".
— Shiro Kanzaki

- Shinji Kido (Kamen Rider Ryuki)
Portrayed by: Takamasa Suga
"I finally made my decision... I want to close the Mirror World. That is my wish, as a Kamen Rider."
Shinji is an naive but energetic young reporter who goes about gathering information "as if he's at a festival, and going to every stall". He is a shining optimist who believes in the best in people, even finding something to admire in Asakura. He is a little slow and clumsy, and has a very simplistic way of thinking. His main flaw is that he wants everyone to be happy; when confronted with a situation where one person must lose for another person to gain, he struggles with the moral dilemma.These qualities would make Shinji the worst kind of candidate for Kanzaki's Rider War, and in fact Shinji's entry into the Rider War was a complete and utter accident. While investigating the home of Koichi Sakakibara (Kanzaki's original candidate) he discovers a blank Advent Deck and is stalked by the dragon monster Dragredder. Yui gives him a chance to live a normal life- to keep the Seal card that would protect him from the Mirror Monsters and give the Deck to her- but after discovering that the Mirror Monsters have been killing people in the real world, Shinji makes the decision to fight. It is an utterly selfless decision, and he only learns of the Rider War after he has been locked into it. But Shinji's resolve remains strong: he decides that he will not fight for the sake of the Rider War, only for the sake of others.Shinji's presence in the Rider War- his innocence and determination- slowly soften the other Kamen Riders, the exact opposite of what Kanzaki wanted. To try and motivate Shinji to take a more active role in fighting, Kanzaki gives him one of the three Survive cards, but this only allows Shinji to overcome even more incredible odds.Yet Shinji always struggles with the question of whether or not it is right to stop the Rider War: whether he has the right to impose his will on twelve others who are fighting for their own personal reasons, or whether they have the right to take twelve other lives in order to fulfill their wishes. Never does this conflict hit him harder than when he discovers that Yui will die, and that only the Prize from the Rider War will save her. He believes that no-one ever listens to him, yet the fact that by this point, no Rider will fight him willingly is proof of the positive effect he had.Shinji eventually discovers his answer. But it is too late, as he takes a lethal stab wound while protecting a young girl during the Raydragoons' invasion of the real world. His last act is to pass on his courage and determination to Ren, so that his closest friend might survive the Rider War.Yet Shinji's efforts were not for naught. Whenever he failed, Shiro Kanzaki would reset time, trying to change the Rider War. Despite not being chosen by Kanzaki, Shinji would somehow become Ryuki each and every time, and would constantly oppose Shiro's plans. Shinji's dogged determination, his actions over the course of several wars and finally his words to Shiro that Yui wanted the war to end for his own sake eventually broke Shiro's obsession. Shiro reset time one last time, to a world where the Rider War never existed. Without him ever knowing, he changed the fates of the Riders, and stopped the fighting for good.
Tropes associated with Shinji/Ryuki:
- All-Loving Hero: Like many Kamen Rider protagonists, he is willing to use his powers to help the innocent instead of using it for selfish reasons.
- Badass Biker: Also rides a motorcycle while not transformed. Survive Form makes Drag Reder into a Transforming Mecha called Dragranzer that can transform him into a bike.
- Batman Grabs a Gun:
- Subverted: Right after he's finally found his desire as a Rider and subsequently his desire to fight and kill, ironically, he dies.
- Shinji generally pulls all the stops when it comes to Takeshi Asakura, the most insane Rider in the war and the only one he truly hates.
- Subverted with him activating Survive Form. He doesn't do it to kill Ren: He does it to make sure Ren stays sane by making sure he doesn't kill him. In other words, he does it to, well, Survive.
- Beware the Honest Ones: His honest nature makes him unpredictable even to those unaffected by Evil Cannot Comprehend Good like Tezuka/Raia, who points this out. Also, he is perceived as this by Takamizawa/Verde in 13 riders special because his goodhearted fumbling threatens the status quo. It leads to him gathering the other riders for collective attack, basically an extermination of Shinji, for the sake of mantaining 'order'.
- Beware the Nice Ones: He's a Nice Guy, but if his enemies (especially Asakura) would pushed him too far, he'll determine to stop them.
- Break the Cutie: The last episodes are firmly dedicated to making Shinji's life suck. His Wide-Eyed Idealist beliefs were already shaky after finding out that the other Riders had very good reasons to want the war. It only became worse when he found out that Yui would die on her twentieth birthday, giving him only one month to find an answer. He actually starts seeking out other Riders to fight, even Ren and Kitaoka, yet he can't find himself to finish them. In the end, he finally finds that his desire is to close the Mirror World... and he dies right after.
- Breakable Weapons: Blank Form's Ride Saber breaks without leaving a scratch on the Monster of the Week.
- Character Tic: Before he enters the mirror world, he pumps his fist and says "Yosha!" Saying Yosha itself also counts.
- Classical Anti-Hero: As the series progress, Shinji wasn't able to avoid the deaths of many Kamen Riders in the Rider War.
- Cool Sword: Drag Saber, resembling Dragredder's tail. The upgraded Drag Visor-Zwei's extendable blade also counts.
- Death by Irony: All the other Riders berated Shinji for not having any desire, and Ren mockingly told him that he would die without finding one and that he didn't deserve to be a Rider. Somehow, Shinji survived long enough to become one of the last five Riders... And died after finally finding his desire to close the Mirror World.
- Dragon Knight: As his American counterpart would say, Shinji's aesthetic and use of Dragreder in his attacks make him this.
- Dragon Rider: While his normal form focuses on the Knight aspect, Survive Form's aesthetic is that of a Dragon Rider, made all the more appropriate when he can jump on his now evolved Dra Granzer and have him transform into a bike.
- Earn Your Happy Ending: Despite dying, Shinji somehow managed to get everyone's wish granted: Thanks to him delaying the end of the Rider War till the end of Yui's birthday and talking some sense into Kanzaki, he convinced him to unmake the War and let everyone live happily ever after. Notably, he's had his idealsim broken in multiple timelines, and his dogged determination persisted each and every time,
- Empathic Weapon: Though not much comes from it, Shinji's Strike Vent Drag-Claw snarls at him when he first summons it, implying it's this.' Justified since it's Dragreder's head.
- The Everyman: For both his own series and the entire FRANCHISE. Where every single Rider before and after Shinji had something to do with the forces that moved the story onward or had some tragic past that defined them, Shinji was just a normal guy who accidentally stumbled into the Rider War. Because AND despite the fact that he had nothing to lose or gain by entering, he gave his all to stop the fighting. This even extends to his powers: He's a Jack-of-All-Stats.
- Evolution Powerup: Has three forms. Blank (initial form), Ryuki (made contacted with Dragredder), and Ryuki Survive (powered-up by Survive card). Each form is vastly more powerful than the previous one.
- Finishing Move
- ''Dragon Rider Kick'': Ryuki jumps and delivers a Rider Kick powered by Dragredder's flames. Actually a Stealth Pun off his name.
- ''Dragon Firestorm'': Ryuki Survive rides Dragranzer, transformed into a motorcycle, which shoots fireballs at the enemy before ramming it.
- ''Dragranzer Clash'': Dragranzer blasts fireballs at the enemy before jumping up and clashes with the enemy with Ryuki Survive riding it. Replaced Dragon Firestorm in first two Kamen Rider Climax Heroes games.
- Friend to All Children: Shinji has a soft spot for children, and three episodes show him saving little girls. One in particular, episode 19, has him risk his life in order to comfort a little girl being held hostage by Asakura, secretly playing dolls with her from afar to calm her down and staying with her as Asakura releases everyone else but holds her for insurance.
- The Hero: The titular rider of this series.
- Horrible Judge of Character: Believes in many riders possibly being good(Asakura being an obvious exception), even when some of them include a corrupt cop who plastered his partner into a wall, a rich kid who thought it'd be fun to get people to kill each other, and a guy who believes he can be a hero by sacrificing other people.
- Heroic Self-Deprecation: By the end of the war, he feels like useless, unable to save anyone or get anyone to listen to him. It's entirely because of him and his idealism that the happy ending was able to take place.
- Idiot Hero: He's not very smart, nor is he very good at judging people. For all that, he can be pretty good at fighting with unusual tactics.
- Incendiary Exponent: During his Final Vent.
- Intrepid Reporter: Tries to become one, though it's hard to be one when he has to be a Rider as well.
- Indy Ploy: Another part of his fighting style. Despite having a very average deck, he thinks up unusual ways of dealing with his enemies that allowed him to survive the majority of the war.Tezuka: You really are unpredictable, aren't you?
- Instant Awesome: Just Add Dragons!: He IS called Ryuki (IE Dragon Knight or Rider). He's contracted to Dragreder, the Unrivaled Dragon, later evolving to the Wildfire Dragon Dragranzer.
- Jack-of-All-Stats: Ryuki has one of the most balanced decks among the riders, with two shields, a sword, and a projectile. His basic form is also this trope among the Evolution Powerup forms. This is even reflected in his Survive Form: His Drag-Visor Zwei is a gunblade that can be used as a sword or a marker for Meteor Bullet, and his Strange Vent can copy cards from other Riders.
- Joke Character: Blank Form, which barely keeps him alive until he contracts with Dragredder.
- Luckily, My Shield Will Protect Me: Drag Shield, which can be dual-wielded, attached to his the hardpoints all over his armor, and even used to ram.
- Meaningful Name: Ryuki means Dragon Knight, but could also mean Dragon Rider.
- Memetic Hand Gesture: Aside from his Henshin pose being Ichigo's, he has his trademark fist pump.
- Mythology Gag: His Henshin pose is Rider Ichigo's signature cross arm.
- Naïve Newcomer: He didn't become a Rider to get a wish, he became a Rider to protect people.
- Nice Guy: For all his idiocy, Shinji is incredibly nice. He constantly tries to stop the fighting, tries to see the best in people even with a serial killer and dedicated his becoming a Rider to protect people from Mirror Monsters.
- Playing with Fire: All of his special attacks are fire-based, given that his mon is a dragon.
- Power Copying: How Strange Vent works in the series, it become the next advent card the opponent going to use. All There in the Manual states that it changes randomly, though. This brings up an interesting 'chicken or the egg' question: how does it "know" what the opponent will choose next? While presumably it is a wild card in The Merch's trading card game, the ability to gain the card your opponent is about to choose is pretty, well, strange within the context of a story. Of course, it could simply be the opponent fighting fire with fire.
- Power Fist: His Strike Vent Drag-Claw. Rarely ever used as an actual gauntlet, but instead as a medium for Drag Reder's Drag-Fire. In crossovers and future appearances by alternate Shinjis, it could breathe fire without Dragreder's assistance.
- Red Oni, Blue Oni: The red to Ren's blue.
- Reluctant Warrior: He'll fight Mirror Monsters, but is reluctant to fight Riders.
- Right Man in the Wrong Place: Shinji's entire place in the war: a completely normal guy with no wish and no desire to fight somehow managed to find an Advent Deck and become a Kamen Rider. This is justified because all the other Riders were picked specifically because they would have a reason to fight, and Shinji can somehow resist Shiro's Time Vent due to not being picked.
- Second Rider: Inverted, as Ren debuted in the first episode.
- Spanner in the Works: It seems that Shinji's entire existence is this trope. No matter what Shiro Kanzaki does or how many times use pushes his Reset Button with Time Vent, Shinji somehow manages to become Ryuki every time. Because of this, he manages to get the Riders to delay or even stop their fighting, preventing Shiro from ever reviving Yui at the cost of the lives of the Riders. Eventually, after many different timelines of having his idealism broken, Shinji finally wins in the end, with Shiro erasing the Rider War from existence. Being who he is, he does all of this without even knowing it.
- Super Mode: Ryuki Survive, which changes his visor to the Drag Visor-Zwei, increases his stats and abilities even more, and evolves DragReder into Dragranzer, who can transform into a Cool Bike for his Final Vent.
- Swiss Army Weapon: Drag Visor-Zwei has a folding blade on it, can shoot beams of light and can be used as a marker for the Meteor Bullet attack.
- Take Up My Sword: Happens to Shinji twice in 13 Riders, first with the original Ryuki, then with Ren after the Ryuki deck is destroyed by Odin.
- Took a Level in Badass: A slow, slow process, but throughout the war Shinji slowly gets better and better at fighting. Towards the middle, he even defeated Asakura before the man contracted other monsters. And then he gets the Survive card, sees more people die, and hardens his resolution even more. By the end of it all, even as he's dying from a stab wound, he manages to take on an entire ARMY of Raydragoons before finally succumbing to death.
- Transformation Is a Free Action: Justified since he generally isn't attacked outside the Mirror World (Aside from the one time Asakura broke his arm). Transforming into Survive Form surrounds him with blazing flames, shielding him from attacks and enemies, thus also being justified.
- Unwitting Instigator of Doom: In Episode Final's timeline, he inadvertently becomes the catalyst of the Rider War when he doesn't play with Yui on a rainy day, causing her to go inside the Mirror World, die, and become a Rider.
- Upgrade Artifact:
- Averted, in that his transformation to Ryuki still leaves him with beginner fighting abilities. He slowly improves his fighting technique as the series progresses.
- Played Straight with Survive Form, wherein he suddenly has knowledge of all his new powers.
- Weapon of Choice: As a balanced Rider, Shinji has three weapons in normal form: The Drag Saber, the DragClaw, and the Drag-Shields. Survive form replaces all three with the Drag Visor-Zwei for the first two and the Fire Wall for the latter.
- Wide-Eyed Idealist: He believes that using his powers as Ryuki is to protect humanity for the better while he tries to stop the fighting between the Riders but he learned he could not stop them because of their selfish desires.
- Ren Akiyama (Kamen Rider Knight)
Portrayed by: Satoshi Matsuda
"Don't fight because you are angry or upset. Fight because you are a Kamen Rider."
Ren is the first Rider introduced, and appears at first to be the epitome of the kind of Rider that Kanzaki wanted in the Rider War: cold, determined and utterly focused on obtaining his wish. He used to be a drifter that would travel the country frequenting bars and getting into fights with people that annoyed him. The person who saved him from this dead-end life was a girl: Eri Ogawa.His contract monster is the batlike Darkwing, the same Mirror Monster that attacked Eri and put her in a coma. Kanzaki appeared then and told Ren that if he won the Prize, he could use it to revive his love. And so Ren accepted the Advent Deck and fought.He got close to Yui Kanzaki because she was useful to him, but that developed into a friendship. He started out as an adamant rival of Shinji, but despite all of Ren's efforts he soon warmed to the boy. Herein lies Ren's flaw: his tough guy persona is merely an act, and given time and reason he will naturally gravitate towards emotional attachment, and friendship. But this in turn led to disaster: Ren was convinced that the only way he could take another human's life- and thus win the Rider War- was to be as cold and emotionless as the mask he wore, and the longer he spent in the company of people like Yui and Shinji the harder it became to pretend. Thus, Shinji inadvertently became Ren's greatest rival, an obstacle that he had to overcome (and never did) to win.He received one of the Survive Cards from Tezuka (who in turn received it from Kanzaki) because the former didn't want to use it. Kanzaki makes several attempts to manipulate Ren into continuing the fight- such as forcing Eri out of her coma for a brief instant to give him a glimpse of his reward- but these things only strengthen Ren's resolve to fight against the system.Following the climax of the Rider War, Ren is the last Rider standing. He fought against Odin and won, if only because of Kanzaki's forfeit. He accepts the Prize and uses it to save Eri, perhaps dying from the injuries he sustained afterward.
Tropes associated with Ren/Knight:
- Badass Biker: One of surprisingly few Riders to ride a motorcycle in the real world.
- Badass Cape: Darkwing can attach to Ren to grant him this, which can defend him from attacks and allow him to fly. Survive Form has this by default.
- Badass Longcoat: It's Ren usual costume.
- BFS: Wing Lancer, though technically, it's a lance that Ren happens to use as a sword.
- Blow You Away: Knight Survive's Blust Vent has Darkraider launch two tornadoes. Using the card itself surrounds him with a barrier of wind.
- Character Tic: Takes out his rapier and poses before jumping into the Mirror World.
- Death by Irony: That depends on whether you think he died at the end: Having discovered that he already killed people long ago and having lost his truest friend, Ren finally throws away his hesitancy to fight and kill... And dies right before he can see Eri again.
- Doppelgänger Spin: Trick Vent allow him to create up to eight copies of himself.
- Hishou Zan: Darkwing forms a cape and cloaks Knight as he uses the Wing Lancer as a drill to destroy a foe.
- Shippudan: Knight Survive rides Darkraider, which transforms into a motorcycle and fires a paralyzing laser followed by wrapping darkness around Ren and itself and drilling into the enemy.
- Jerk with a Heart of Gold: Cares about Eri and Yui, and eventually about Shinji.
- Image Song: Lonely Soldier
- Lightning Bruiser: Ren has a pretty versatile Deck. His Trick Vent provides him with clones to give him backup, he has a Sword Vent and his rapier to deal close range damage, Nasty Vent to help him GET close, a Guard Vent for sticky situations, and his Mirror Monster can attach to him to help him fly. Problem is, he has no long-range options. Survive Form takes away this weakness while making him even MORE powerful.
- Make Me Wanna Shout: Nasty Vent has Darkwing attack the opponent with sonic waves.
- Only Friend: In all 3 continuities (movie, TV special, series), Ren pretty much admits that Shinji is his only friend.
- Red Oni, Blue Oni: The blue to Shinji's red.
- Royal Rapier: Dark Visor, which gives him a slight advantage over some others in that he doesn't have to use a card to have a weapon on hand.
- The Stoic: He keeps a cold and aloof persona most of the time.
- Super Mode: Knight Survive
- Swiss Army Weapon: Dark Visor-Zwei, which can change into a sword, a shield or a crossbow.
- There Can Only Be One: He's the last Rider standing in the Rider War.
- Took a Level in Kindness: Over the series, he eventually comes to consider Shinji as a true friend and is very reluctant to kill him. He doesn't deny allegations of them working together when Imperer comes in, and where he originally would've strangled Shinji without hesitation, his final fights with him actually have him unable to raise a blade at him when his friend is ranting about what he should do to save everyone.Shinji: I won the last battle. You didn't fight seriously, did you?
- Weapon of Choice: In normal form, he has the Wing Lancer, a lance he uses as a sword and his Royal Rapier Dark-Visor. The Dark-Visor Zwei in Survive Form houses a sword and can transform into either a shield or a crossbow.
- Masashi Sudoh (Kamen Rider Scissors)
Portrayed by: Takeshi KimuraThe first truly evil (and a Mauve Shirt) Kamen Rider to grace the entire franchise who wasn't a Red Shirt nor is redeemable like Shadow Moon.Sudoh was a Corrupt Cop who was taking advantage of his position to carry out a variety of evil acts. After he killed his partner-in-crime for demanding a bigger share, Kanzaki appeared before him to give Sudoh an Advent Deck. It's not known what Sudoh would have chosen as his Prize (in fact it's not even hinted that Kanzaki even told him about it); to him, the greatest advantage of being a Rider was that he now had a perfect method of disposing of anyone who got in his way (by feeding them to his crablike contract monster Volcancer).Shinji first meets Sudoh in battle as Kamen Rider Scissors, and despite Ren's warnings the naive Rider attempts to befriend Sudoh. Sudoh exploits this for all it's worth, gaining information that allows him to target Ren and Yui, culminating in his later attempt to murder Shinji himself.After his cover is blown by Reiko's investigations, Sudoh duels Ren within the Mirror World. Sudoh's bad karma catches up to him when Ren shatters his Advent Deck: with the contract to his Monster broken, Volcancer goes wild and consumes Sudoh, body and soul.
"Just trying to be as efficient as possible."
- Corrupt Cop: Plastered his partner in a wall after he demanded a bigger share, used his job to cover his illegal acts, and feeds anyone who gets in his way to his contract monster .
- Death by Irony: He fed people to his Mirror Monster to make it more powerful, and died by getting eaten by said monster.
- Finishing Move: Scissors Attack note
- Improbable Weapon User: Scissors Pincer, which is just one of Volcancer's claws.. Also his Scissor Visor, which is sort of a blend of shears and Blade Below the Shoulder.
- Jerkass: When he reveals his true colors.
- Joke Character:
- Has the worst deck among the riders. Advent and Final vent aside, all he has are a Strike Vent (which is kind of an awkward weapon to use) and a Guard Vent, no special cards whatsoever like Raia's Copy or Gai's Confine; on top of that, his cards have very low AP.
- In terms of the series, though, he was less Joke Character and more Starter Villain—the inexperienced Shinji wouldn't have stood a chance against the heaviest hitters in the Rider War early on, and really had his hands full with this first "real" enemy.
- Despite being a Starter Villain, he was actually winning his fight with Ren before his Advent Deck is broken.
- Luckily, My Shield Will Protect Me: Shell Defense, shield that resembles Volcancer's back armor.
- Sacrificial Lamb: His entire existence showcased two aspects: Riders being jerks, and the consequences of breaking a Contract.
- We Hardly Knew Ye: Gets killed off in the two-episode arc that introduces him. Even Imperer lasted longer than him!
- The 13 Riders special had him make an alliance with Shinji to stop the Rider War, which was a ploy to get Shinji killed by him and other Riders. He doesn't get to do more as Ouja appears and kills him, both for his desire to fight and his distaste for cops.
- Weapon of Choice: Like those of every Rider in this series, they're part of his contract monster, Volcancer.
- Shuichi Kitaoka (Kamen Rider Zolda)
Portrayed by: RyoheiA self-proclaimed "Super Lawyer", Kitaoka prides himself on being able to get the Innocent verdict every single time even if the person or company he is defending is clearly guilty. This reputation led to him acquiring the nickname of "The Black-Or-White Lawyer" and a lot of enemies in some very nasty places. But Kitaoka doesn't do it for the morals or even the money: he does it because he can, because he loves knowing that he is the best. And he will refuse cases which even he sees as impossible (such as Asakura), preserving his own pristine court record.Despite his smugness and success at life, Kitaoka has a nasty secret: he has terminal cancer. Instead of going into treatment in order to delay the inevitable, Kitaoka chose to live his life as normally as possible and hide his cancer from everyone except his manservant Gorou. He is also Kamen Rider Zolda, and his wish is simple: immortality, to survive his cancer and "do whatever I want, for however long I want".During the early stages of the Rider War, he comes off as an incredible dick. He fakes Zolda's death in order to break Shinji's morale and force the boy to quit the War. He saw his act as just another way of fighting the War; he may have felt guilty had he known that it pushed Shinji to the brink of suicide. As the Rider War progresses and he becomes closer to the other participants- especially Shinji- he comes to terms with his mortality and loses his desire to win. As he puts it, "I've already lived a pretty awesome life."At one point he develops a crush on Reiko and pursues her for the rest of the series, sending her presents and dropping cheesy pick-up lines that the fiercely independent Reiko rejects every time. He also makes an enemy of Asakura by refusing to represent him in court because of his certain guilt, but mostly because he doesn't like him.At the climax of the Rider War, he finally gets Reiko to go on a date with him. But feeling responsible for Asakura's transformation into a Rider and subsequent reign of terror, he is determined to finish things with his arch-rival first. He does neither, for the cancer that had been stalking Kitaoka for so long finally cripples his body, and he dies peacefully in his home.
"I can do whatever I want, for however long I want. Is there no greater prize?"
Tropes associated with Kitaoka/Zolda:
- A Load of Bull: Magnagiga, and outside of Dragedder and Venosnaker, it's the largest Mirror Beast, so much that the prop is too big to use in fights, so all it does it take part in his Final Vent.
- Amoral Attorney: Willing to do anything to get the verdict he desires, regardless of whether the client is innocent or guilty.
- Arch-Enemy: To Asakura.
- Awesome, yet Impractical: His finisher End of the World. It lives up to its name in destructive power, but the long time it takes to prepare it means it usually won't hit people.
- BFG: Giga Launcher, a huge cannon that's formed from Magnugiga's arms. It's comparable in size to an actual artillery gun of some sort, and is nearly twice Zolda's height!
- The Charmer: Shinji develops quite a strong admiration for him when he has to spend time with him to make a report about him. Subverted with anyone who's been on the wrong side of his Amoral Attorney practices or the actions he commits during the Rider War.
- Combat Pragmatist: He rarely takes part in direct fights, and one of his preferred methods is sneak up a on fight in progress and try to kill the combatants with his Final Vent.
- Death by Adaptation: The show had him become one of the four finalists destined to fight Odin while one of the S.I.C. stories had him die and replaced him with Tiger as one of the finalists.
- Death by Irony: His illness was one of the main reasons he became a Kamen Rider. Because of his illness, he also had to stop being a Rider.
- Funnily enough, his Final Vent never killed any Rider despite its destructive power. A S.I.C. story had him kill Asakura after the latter used stolen Advent Monsters to create Genosurviver with his Final Vent, only to get killed by the blast of his own attack.
- Dramatic Gun Cock: Justified. He can fire Magna Visor without cocking it, but he has to cock it in order to load and use his Advent Cards.
- Finishing Move: End Of World note
- Graceful Loser: When cornered and about to be beaten up, Kitaoka's last tactic is to drop to his knees and beg for mercy. Subverted when he actually used this opportunity to call for the police.
- The Gunslinger: His visor is a handgun, his deck has two long range weapons, and his contact monster is loaded with large number of missiles, cannon and beam gun. Notably, he had a Strike Vent and another Guard Vent that were never used in the series because the former completely went against his style, and the latter was just plain redundant.
- Handguns: Magna Visor, a handgun with very impressive rate of fire. Like Ren, this gives him the advantage of having a weapon even before using any cards.
- The Hedonist: His reason for wanting to live forever? So he has more time to enjoy life.
- Horn Attack: His Strike Vent, unseen in the series but detailed in side materials, is Magnugiga's head mounted on his arm and serving as a katar.
- Image Song: Kienai Niji
- Immortality: His wish for winning the Rider War.
- Jerk with a Heart of Gold: Can show a kinder side to those who are in a similar position as him, such as paying for medical treatment for a girl's mother in spite of his dislike for children.
- Luckily, My Shield Will Protect Me: Giga Armor and Giga Tector. The latter is never used in the series and the former is very, very rarely seen.
- Multi-Ranged Master: His visor is a handgun, he hastwo BFG weapons for multiple situations and his Final Vent has him use Magnagiga to unleash everything in his arsenal.
- Pet the Dog: Since he's terminally ill, he has a soft spot for people in similar conditions, doing things such as pay for the operation to save the life of a young girl's mother and going a date with an old girlfriend of his that he thought was terminally ill, though the latter turned out to be a misdiagnosis.
- Power Fist: Giga Horn, resembling Magnagiga's head. Never used in the series, though it WAS used in the video game.
- Shoulder Cannon: Giga Cannon, a double beam cannon that resembles Magnu Giga's legs.
- Soap Opera Disease: He starts showing symptoms towards the end of the series, as they become more severe.
- Took a Level in Kindness: He becomes less antagonistic to Ren and Shinji as the series progresses. During the early episodes of his screentime, he tries to find ways to kill both of them, but this fades away after a while. He eventually gets a sort of working relationship with them. Near the end of the series, he indirectly shows he cares a little bit for Shinji after he tells Ren about his suicidal Heroic B.S.O.D..Kitaoka: How is Kido now?Ren: Well... He's the same as usual, isn't he?Kitaoka: Ha! Idiots do recover quickly. Well, I suppose I can acknowledge him a bit now.
- Weapon of Choice: Like those of every Rider in this series, they're part of his contract monster, Magnugiga. Notably, some of them (i.e. the shields and Power Fist) don't mesh with his ranged-combat style.
- Jun Shibaura (Kamen Rider Gai)
Portrayed by: Satoshi IchijoThe spoiled son of a rich businessman, Jun had the money, intelligence and free time to treat life as a game. His first act in the series was to create a computer game that sent subliminal messages to the player, stimulating their base fighting instincts and urging them to recreate the battle royale of the game in real life. He intended to distribute the program to every one of ORE Journal's subscribers, creating a city-wide orgy of violence. To Jun, this was just a way of making his life more fun.He presumably joined the Rider War because he saw it as the ultimate game; his intended Prize for winning was unknown. His Contract Monster, the powerfulMetalgelas, compensated for Jun's natural lack of strength and fighting experience and put him on equal ground with the other Riders. Perceptive and manipulative, Jun noticed Ren's hesitancy to deliver an almost fatal blow and exploited that weakness for all it was worth. He was also the first to discover the civilian identities of all the other Riders, a fact that filled him with glee.When Asakura became a Rider, Jun was happy to fill the new guy in on some of the rules and point him in the direction that would cause maximum conflict. Though Jun probably acknowledged that Asakura was dangerous, he simply saw him as another wild card that would make the Rider War even more interesting for himself. Perhaps he even thought he could manipulate the madman. He never expected that Asakura would use him as a human shield against Zolda's End Of World attack, and turn on him without a moment of hesitation or gratitude. Jun cursed Asakura, saying that he was supposed to make the game fun for him, but the murderer simply shrugged and said that it was his fault for being close, and quickly finished him off.And so, fittingly, the manipulator died to the manipulated.
"You were supposed to make my game more fun..."
- Anti-Magic: Confine Vent. When played just after another Rider plays a card, this will cancel the effect (de-summoning a mon or causing a weapon to disappear).
- Asshole Victim: Only Shinji cared about his death, and it was more out of principle.
- Death by Irony: He loves manipulating people in order to seem better than them, and thus created a six way battle between the Riders. Fittingly, he was killed by one of the people he thought he had under control, Asakura.
- Evil Is Not a Toy: As noted above, he helps Asakura get acclimated to the Rider war to make it more exciting, and also likely for the purpose of using him. It doesn't exactly pan out.
- Finishing Move: Heavy Pressure note
- Insufferable Genius: He's intelligent, observant, and uses it to treat people like crap when he's not manipulating other people.
- Jerk Ass: One of the greatest ones in the series, ranging from being a Mean Boss to ORE employees to Insufferable Genius to everyone else.
- Mean Boss: His brief time as a boss of ORE shows him mistreating his employees, even having Shinji putting on a ridiculous costume to make promotions, forcing him to write an article about him, and threatening to burn his card, which will result in Shinji's death.
- Power Fist: Metal Horn, resembling Metalgelas's head. Due to its big size and its shape, it can also be used as a shield.
- Spoiled Brat: He's described to be the son of a rich businessman, which can be seen when he announces himself as ORE's new boss.
- Unskilled, but Strong: Truth be told, while he can competently fight, when the other Riders finally get it in their heads that they REALLY want to fight this guy, he doesn't stand a chance. He only survives due to his form's heavy defense, his cunning manipulation and the fact that his opponents generally don't want to fight him.
- Weapon of Choice: He only has one "weapon" to speak of, that being the Metal Horn.
- Miyuki Tezuka (Kamen Rider Raia)
Portrayed by: Hassei TakanoTezuka is a young fortune teller who plays his trade on the streets, and boasts that his prophecies are always correct. Due to this, he believes that destiny is predetermined and cannot be changed. Tezuka is also the only other Rider aside from Shinji who is against the Rider War, and works to stop the in-fighting between the Riders. Due to this, he becomes fast allies with Shinji.Tezuka's opposition to the Rider War becomes clear when it is discovered that he was never intended to be a Rider in the first place: instead, a good friend of his- Yuichi Saito- was chosen, but refused to participate and was devoured by the Mirror Monster Guldthunder. Taking his Card Deck, Tezuka contracted Evildiver and vowed to avenge his friend.Because Tezuka refused to participate in the Rider War, he was a hindrance to Kanzaki. At first, Kanzaki attempted to motivate Tezuka by giving him a major advantage: the first of the three Survive Cards. Tezuka didn't even consider using it, instead giving the card to Ren. In retaliation, Kanzaki ordered Guldthunder to attack Tezuka, successfully triggering a berserk rage in the young man towards his friend's killer. However, after defeating the Monster Tezuka returned to normal.He and Shinji always clashed on the question of whether or not it's possible to change your own fate. When Tezuka predicted that Ryuki would be the next Rider to die, he panicked and lied to Shinji by telling him that Raia was the fated one. Later, when Ryuki and Ouja fought, Tezuka pushed Shinji out of the way of a lethal Final Vent and took the blow himself. He had changed his own fate, but ironically fulfilled a false prophecy at the same time.Shinji manages to drag Tezuka into the real world before he dies, sparing him the fate of dissolving in the Mirror World. In his dying moments, Tezuka seems to realize that Yui is the key to everything, yet is unable to communicate this to Shinji before he dies.Despite the multiple timelines seeming to prove that it WAS impossible to change fate, the fact that the Rider War finally reset to being no more proved him wrong, and in a roundabout way he achieved his dream in the end.
"My predictions are never wrong."
Tropes associated with Tezuka/Raia:
- Blessed with Suck: He's blessed with the gift of prophecy, which allowed him to find two Riders (Ren and Shinji)easily whereas many contestants have trouble finding one. However, he's troubled with his power because he sees death and misfortunes with his clients, hence why he strongly believes in that people can Screw Destiny if they prepare.
- Dark Is Not Evil: Yes, the Rider with an arsenal mostly starting with "evil" is a good guy.
- Finishing Move: Hide Venom note
- Death by Irony: He predicted that Shinji would die next, but lied to Shinji saying that he himself would be the one to die. He performed a Heroic Sacrifice for Shinji, averting his true prophecy yet fulfilling his fake one. My predictions are never wrong indeed.
- Evolution Powerup: The SIC stories gave him a Survive Form.
- Go Out with a Smile: He finally manages to Screw Destiny to save Shinji, dying happily as he believed his friend Yuuichi had no regrets just like him and believing Shinji would change the fate of the Riders.
- Heroic B.S.O.D.: Pretty much half of what caused his death was being told that his best friend Yuuichi, the man who was supposed to be Raia instead of him, regretted never participating in the Rider War to fulfill his wish, even if it meant killing. This gave Tezuka a crisis of faith that left him unresponsive, leaving Asakura to give him a No-Holds-Barred Beatdown that forced Shinji to save him...only for Tezuka to due saving him when Asakura proved to be too much for him.
- Heroic Sacrifice: Pretty much the main reason of his death besides Asakura giving him the death blow.
- Incorruptible Pure Pureness: Even Asakura's presence doesn't motivate him into fighting.
- Luckily, My Shield Will Protect Me: Evil Visor, a small shield in the shape of Evildiver.
- Names to Run Away from Really Fast: Evildiver, though it's a subversion since its user is one of the undisputably good Riders.
- Nice Guy: Cares about Ren's emotional welfare and is the only one that supports Shinji's plight to stop the Rider War.
- O.O.C. Is Serious Business: He enters into an Unstoppable Rage when he finds the monster that killed Yuuichi, even pushing Shinji away and telling him to not interfere despite being the Rider with whom he has the best relationship.
- Power Copying: Copy Vent, which allows him to wield a duplicate of his opponent's weapon.
- Revenge Before Reason: He seems to subvert this trope as his main objective is stopping the war and he only returned to the revenge issue once the monster that killed his friend appeared, and yet he was capable of fighting effectively in spite of his enraged state and quickly came back to normal once he achieved it. He also averts this trope when Kanzaki reveals that Asakura was the one who broke Yuuichi's fingers, which caused him to join the Rider War and die when he refused to participate. Tezuka refused to fall for the bait, giving Ren his Survive Card instead.
- Unstoppable Rage: Against the monster that killed his friend.
- Weapon of Choice: Sting Vent, a whip, is his base weapon, but he prefers to copy other Riders' more powerful and balanced weapons.
- We Used to Be Friends: With Ren in the 13 Riders special.
- Whip It Good: Evil Whip. Resembling Evildiver's tail, it isn't really powerful, but has good reach.
- You Can't Fight Fate: By irony. He predicted Shinji would die, but lied and said he himself was the next one to die. Later, Shinji was about to be killed by Ouja, but Tezuka made a Diving Save and took the hit for him, proving his faked prophecy correct. He didn't mind at all.
- Takeshi Asakura (Kamen Rider Ouja)
Portrayed by: Takashi HaginoAsakura is not a hero. Nor is he an Anti-Hero. Nor is he misunderstood. He is a psychopath, plain and simple.He is drawn to violence, feeling an unbearable tension that can only be eased through fighting. When confined in a jail cell, he becomes so frustrated that he begins banging his head on the wall until he draws blood. Yet he is not mindless; he is capable of intelligent manipulation and does not make stupid decisions. Kanzaki could not have picked a better Rider; an assessment that is immediately proven when Asakura kills Gai in his first battle as Ouja.Kitaoka is initially assigned to defend Asakura in court, but the "super lawyer" takes a dislike to his client and smugly tells him that there's nothing he can do. This ignites a rivalry that lasts for the entire series.Asakura racks up the highest body count of all the Riders, killing Gai, Raia, Imperer and Zolda. When the monsters of Gai and Raia come to exact revenge for the death of their masters, Asakura binds them to his will instead, making him the only Rider with three Contract Monsters and gaining access to all of Gai and Raia's powers. Furthermore, he can use Unite Vent to fuse them into one, creating Genocider, the second most powerful Monster in the series. The disadvantage is that he now has three monsters to feed, something that nearly leads to his death when he starves his monsters and they threaten to devour him.At the climax of the Rider War, the Japanese police force are given orders to shoot Asakura on sight. But Asakura will not surrender, not until he has killed Kitaoka in battle. And so he faces Zolda in battle, and finally lands the killing blow he had been waiting so long for... only to find out that Gorou had taken Kitaoka's place as Zolda. Asakura could not comprehend it: why he had been robbed of something he had waited so long for and wanted so badly, and why Gorou had selflessly taken Kitaoka's place. Overcome with frustration and rage, he makes a suicide run at the police and is shot down like a dog.
"Being a Rider is fun."
Tropes associated with Asakura/Ouja:
- 0% Approval Rating: Almost everybody hates Asakura. Hands down.
- Arch-Enemy: To Kitaoka.
- A Sinister Clue Appears to be left-handed, judging by his fighting style using his sword in his left hand.
- Awesome, but Impractical: Having contracted with three Mirror Monsters (his original Venosnaker, then Metalgelas and Evildiver taken after killing their Riders), he gains at least some cards from their decks (their associated Final Vents and weapons; he's never shown using Raia's Copy or Gai's Confine), allowing him three different finishing moves AND the ability to fuse them into Genocider. However, it means he has three times as many mons to feed, which is a problem for him when he doesn't feed them for a while.
- Big Bad Wannabe: The most active, in terms of directly fighting the protagonists, villain the series, and typically is the biggest threat to them unless Odin shows up. In most series with a There Can Be Only One format, he'd likely have been the Big Bad, but Kanzaki using Odin means he never had a chance of winning the Rider War and in the end is largely Kanzaki's pawn.
- Big Brother Bully: He didn't have a good opinion of his younger brother, saying that he always was on his way. Likewise, his brother doesn't want to remember him.
- Blood Knight: The wish he'll have granted if he wins? To have the war go on for eternity. He didn't even know about that part of the battle for most of the series, Kanzaki's promise of fighting was all it took to draw him in.
- In one fight with Shinji and Ren, he even gets so lost in the thrill of it that he nearly stays in the Mirror World past the time it's safe for him and nearly dies. When he returns to the normal world, he's still so thrilled that he picks up a crowbar and rushes at them, intending to continue the fight as humans. He faints out of exhaustion, which causes Shinji and Ren to run rather than take any chances with him.
- Cain and Abel: He's the Cain to his brother's Abel. The fire that made him a Self-Made Orphan was primarily intended to kill his brother. He even tricks Reiko into bringing his brother to him so that he can kill him with his monster, once he finds out he's alive.
- Catch-Phrase: Whenever he finds something that annoys him, he'll say "This vexes me..."
- When he fights people he's fought and tried to kill before, he sometimes says "Now, a continuation from yesterday/before..."
- Character Tic: He cracks his neck and breathes "Ahhh" before jumping into the Mirror World.
- Consummate Liar: Surprisingly, he managed to spin a convincing lie about trying to save his younger brother during the fire that burned their house down.
- Cool Sword: Veno Saber, resembling Venosnaker's tail. Initially, his ONLY weapon before killing other Riders and getting their monsters. It's the most balanced melee weapon among his Weapon of Choice.
- Crazy-Prepared: When caught in a trap by Kitaoka that got his deck stolen, he kept the Contract Card for Metalgelas underneath his shirt, have apparently guess Kitaoka might have been trying to trick him.
- Death by Irony: Asakura finally got what he wanted since the start of the war: To fight and beat Zolda. Unfortunately, he killed Gorou, and not Kitaoka. Sickened and maddened by dissatisfaction, he purposely walks into a police ambush and dies without a fight.
- Similarly, despite being a serial killer who killed many Riders throughout the war, he never actually managed to kill the ones he wanted to kill the most (Zolda of course, then Shinji, then Toujou).
- Determinator: Put him in jail? He'll escape! Time limit runs out in the middle of a good fight? Continue until you're expelled from the Mirror World and then keep fighting in the real world! A two way fight turns into a three way fight featuring your two most hated Riders and ends with your current prey escaping and your most hated rival victorious while you're panting and bloody? Smile and ask him if he wants to fight! This guy won't stop fighting until he's out cold or dead.
- The Dragon: In a weird way. He is surprisingly amicable towards Shiro Kanzaki for freeing him from jail and giving him the chance to fight, and offers him food and does his bidding if he approaches. Of course, since those requests all involve killing people and he'd probably kill Kanzaki and Odin if he had the chance, this doesn't exactly hold.
- The Dreaded: Being a killer, he's quite a source of panic to those who recognize him.
- Evil Cannot Comprehend Good: Hinted at when he killed his younger brother, as he had difficulty understanding why anybody cared that he did it in the first place. Later on, when a little girl that bonded with him gave him a flower, he stared at it because he didn't understand why she would give him such a useless thing.
- Evil Is Bigger: His first Mirror Beast Venosnaker is among the largest to appear in the main series, a little bigger than Dragredder. Then he merges him with Evildiver and Metalgeas, and Genocider is DAMN big.
- Evil Is Petty: Naturally given his temper.
- Evil Is Stylish: It's no fun for him to kill an opponent outside of a rider battle, so even though he gets fair of number of chances to, he never does so. That doesn't mean he won't play dirty BEFORE the fight, and he certainly doesn't care for non-Riders.
- Evolution Powerup: The SIC stories gave him a Survive Form.
- Finishing Move: Has two of his own, plus Gai and Raia's after taking their Contract Monsters.
- Veno Crash: Venosnaker launches Ouja at the foe with a spray of venom as he does a bicycle kick.
- Doomsday: Ouja corkscrew kicks a foe into a vortex that opens within Genocider.
- Fusion Dance: His Unite Vent, combining the three monsters he gained. The SIC stories gave him a Super Mode, and made the card forcibly fuse EVERY REMAINING MONSTER IN THE WAR. Of course, since one of those monsters was Dragreder, still contracted to Shinji, it didn't go the best way for him.
- Hair-Trigger Temper: He is VERY prone to violent outbursts against anyone that even slightly annoys him, and if there's nothing around he'll just beat on whatever random object is near by even if involves beating his head on a concrete wall or punching glass.
- Hate Sink: He has zero redeeming qualities and all of his screen time is dedicated to him hurting others.
- Hero Killer: For a very vague definition of "Hero". He has the highest Rider kill count in the series (Gai, Raia, Imperer, Zolda).
- Image Song: Spinnin' Around
- Implacable Man: Combines this with The Determinator. Getting caught in trap build to burn the victim alive means he reappers not so long afterwards only slightly charred. His Contract monster's corrosive spit melting through his helmet and onto his face only puts him out of the equiation for about as long. He has to be gunned down by a shooting squad.
- Iconic Outfit: His snakeskin jacket.
- Irony: Despite being very willing to kill, and having the biggest kill count among the Riders, if he deliberately targets someone, he never manages to kill them. This is made the most apparent with Kitaoka.
- Despite having the highest kill count of all the riders in the series, he also has died the most of all the Ryuki riders - first, he died at the end of the TV series being gunned down by the police. Then, in Episode Final, he was killed by Femme when the latter destroyed his Contract Deck. Then he is killed off by Mach's Dead heat along with Dark Kiva in Kamen Rider 4, and then in Beast Rider Squad special, he's killed by Kamen Rider Brave while the latter is using the Knight of Safari Gashat.
- Jerkass: The biggest in the series, particularly when he's "vexed."
- Jerk with a Heart of Jerk: When he found out via Reiko that his younger brother was still alive from the house fire that killed their parents, he told her he tried to save him at the moment, and wanted to be reunited with him. But then he reveals that he actually caused the fire himself, and proceeds to have Venosnaker eat his own brother.
- Happens again, in the two-parter where he apparently saved and took care of a little girl who was the sole survivor of a Mirror Monster attack on a ferry. Turns out he was just using her as bait to fight said monsters and feed his own.
- Joke Character: Blank Form, seen only once in Episode Final after Genocider is killed.
- Kick the Dog: Killing his bother.
- Kick the Son of a Bitch: Turning (and literally) on Jun. Nobody but Shinji cared.
- Knight of Cerebus: The Rider War wasn't exactly puppies and sunshine, but before Asakura came on the scene, only one Rider—a clearly evil one, at that—had died, and the current five at that time weren't doing all that good a job at the whole killing each other thing. That changed once he became Ouja, and he's responsible for four dead Riders, a little below a fourth of all of them.
- Magikarp Power: His deck. Advent and Final Vent aside (the latter of which did succeed in killing whatever target he hit it with), it started with just a Sword Vent and nothing else. However, it is the only deck that has spare Contract Cards. By the end, he has three melee cards and three mons, which can be fused into the formidable Genocider.
- Pet the Dog: He gets one moment: when he stays with a young girl (who viewed him as her saviour) until her recovery even when he no longer needed to.
- Subverted since he only stayed near her because she was targeted by a trio of Mirror Beasts and he was hoping to kill them when they showed up. When a hungry Venosnaker hits her trying to attack him, he doesn't even flinch.
- Power Fist: Metal Horn, after Ouja becomes contracted to Metalgelas. Stronger but shorter than his Veno Saber.
- Purple Is Powerful: His color scheme is purple and he has the highest kill count in the Rider War.
- Save the Villain: Shinji saved him from being devoured by his own Mirror Monsters. He did this because he supposedly saved a little girl, but in reality he was just using her as bait for other Monsters. Shinji still finds saving him justified, and in a trope view it still is, because if he died the girl would have gone into severe depression.
- Screaming Warrior: Tends to scream a lot when he's feeling vexed. It mainly happens outside of battle when he's feeling bored or disappointed when things don't go his way. It rarely happens in battle since he's too much of a Blood Knight to not enjoy himself in the thrill of it...unless he's pissed with the opponent in question, such as Tiger or Goro when it was revealed he was Zolda rather than Kitaoka.
- Self-Made Orphan: He burned down his own house as a child trying to kill his younger brother.
- Up to Eleven: The What If? scenario of SIC Hero Saga not only gives him Survive Form, but also upgrades the Genocider into Genosurviver, formed by combining every contract monster into one, even the ones with Riders still alive. Of course, since Dragreder is still contracted to Shinji at that point, it's not exactly obedient.
- Villainous Breakdown: When he kills his archenemy Kitaoka / Zolda, he discovers that it wasn't Kitaoka wearing the suit and the real Kitaoka died peacefully at home during the fight. This pretty much results in him allowing himself to be gunned down by the police.
- Weapon of Choice: When he contracted Venosnaker, aside from the obligatory Advent and Final Vent Asakura only had a grand total of ONE card : Veno Saber. Even when he receives the powers of other Advent Decks, he still prefers using it over the others. Justified, since in the real world he often uses a metal pipe to fend off police, and Veno Saber is shaped like one.
- Whip It Good: Evil Whip, after Ouja becomes contracted to Evildiver. The weakest of his Weapon of Choice, but has the longest range.
- Would Hurt a Child: He has no trouble using a little girl as a leverage during a hostage exchange to engage Kitaoka in their first fight.
- Would Hit a Girl: Knocks Reiko unconscious and attacked her before when he first went for Kitaoka, has no trouble trying to kill Femme, killed her sister for fun, and has no trouble using a little girl as a hostage.
- Satoru Toujou (Kamen Rider Tiger)
Portrayed by: Jun TakatsukiSatoru Toujou might have just been another one of many 25 year old men had Kanzaki not selected him to become a Kamen Rider. Unknown to Satoru, the day he made the choice to accept Kanzaki's offer was the day his life—-as well as the lives of those closest to him—-would be forever ruined.A man of subdued character, Satoru is arguably no less deranged than the likes of Asakura, possessing a sociopathic mentality that forces him into single-mindedly pursuing one goal: becoming a hero. He confesses to Sano at one point that he has never had many friends, and that he believes that if he becomes a hero, people will like him.As a student of Semeiin University, Satoru had become very close to one Professor Kagawa, who took the young man under his wing and was probably the closest thing Satoru had to a father figure. It was perhaps little surprise that Satoru initially chose to side with his mentor in their quest to destroy the Mirror World. Kagawa impressed upon the young man his utilitarianist philosophy that a hero was someone who has the courage to sacrifice one person- even those closest to them- to save ten.Alas, Kagawa's mantra had an unintended effect: Satoru reasoned that Kagawa's philosophy would work in reverse, and that by sacrificing those closest to him he would achieve his dream of becoming a hero. This conclusion was only reaffirmed by Kanzaki's Rider War: all of his closest friends were Riders, and if Satoru was the last to remain then he could use The Prize to become a hero. And so when Kagawa let down his guard, Satoru attacked, shedding tears as he killed the most important man in his life.Perhaps his most vile act, however, occured after the professor's murder. After a bad run-in with Asakura, Satoru was rescued by Sano Mitsuru AKA Kamen Rider Imperer, who had previously allied with both Satoru and Professor Kagawa. Providing a safe haven for Satoru, Sano asked if they were friends, a statement which the former confirmed claiming that besides Professor Kagawa, Sano had been the only person who'd been kind to him. Later that day, Satoru betrayed Sano, stabbing the latter in the torso and leaving him for dead, cementing the insane Rider's villainy.He would only grow more unbalanced as the days passed, culminating in an attempt to eliminate all the Riders at once. While his attempt failed, Satoru was convinced he'd succeeded cackling as he made his escape. Yet, the words of his former idol haunted him, and from across the street, Satoru witnessed a man and his son, rekindling in Satoru the memory of his deceased teacher and his own child. As a truck careened into the family, Satoru- unthinkingly- ran to push them out of the way, sacrificing himself for their sakes.As he lay dying, Satoru yet found himself wracked by his inability to attain his wish, never knowing that his final act had made him that which he'd desired to be all along: a Hero. As he finally closed his eyes, the tragic story of a man consumed by his own hubris came to a silent conclusion.The next day, a crumpled newspaper is seen blowing across the streets. The latest news is of a man who sacrificed himself to save two others, and became a hero...
"You're an important person to me. If I sacrifice you, maybe I'll become stronger."
Tropes associated with Toujou/Tiger:
- An Axe to Grind: Dest Visor, a battleaxe. Like Knight and Zolda, this gives him the advantage of a weapon even before using a card.
- Apologetic Attacker: Toujou apologizes to both Kagawa and Sano after betraying them. It's debatable how sincere said apologies were.
- Awesome, yet Impractical: His Finishing Move is brutal, but easily stoppable if the enemy is fully aware. * Ax-Crazy: Asakura and Kitaoka notice that Toujou is Not So Different with the former after a fight between the three of them.
- Chronic Backstabbing Disorder: He did this to his colleague, to his mentor, and to Sano. It costs him dearly as he starts losing his fights more frequently now that he's alone. The worst part is that his philosophy of sacrificing others didn't make him any stronger.
- Combat Pragmatist: Attacks his opponents from behind with his Final Vent or when he's teaming up with someone else. This is why he's been capable of defeating the likes of Asakura, Kitaoka, and Shinji. Unfortunately for him, the former two are more than eager to pay him back in the form of one Curb-Stomp Battle after another.
- Death by Irony: He constantly sacrificed others in order to try and become a hero. He died sacrificing himself to save a father and son, and was called a hero the next day.
- Diving Save: Performs one to save a father and son from a traffic accident.
- Finishing Move: Crystal Break note
- Gone Mad From The Revelation: His mental health was always bad, but hearing from Asakura that he failed to kill Sano, he loses it even more.
- Hair-Trigger Temper: Starts to show up more as his insanity becomes more evident. As his defeats start to pile up and he's mocked by both Asakura and Kitaoka, Toujou starts to scream and break mirrors with his fists in moments of rage.
- Heroic Sacrifice: Commits one to save a father and son from a truck, committing his only heroic deed in the series and ironically fulfilling his wish at the moment of his death,
- Heroic Wannabe: A truly frightening example given his instability.
- An Ice Person: Freeze Vent. It does exactly what it sounds like, freezing enemy Contract Monsters (but curiously, not Riders themselves).
- Insane Troll Logic: The reason he becomes a villain: If being willing to sacrifice those close to you makes you a hero, actually sacrificing those close to you makes you MORE of a hero.
- Laser-Guided Karma: His betrayal of Sano leaves him all alone, and hearing from Asaskura the he failed to kill him causes him to fully lose it.
- The Needs of the Many: An avid believer, but he never saved anyone.
- Not So Different: Both Kitaoka and Asakura notice that Toujou is quite similar to the latter after their fight with him.
- Panthera Awesome: His design theme and Destwilder's.
- Spared by the Adaptation: Gets to make it to the finals in the S.I.C. story World of If along with his teacher...only for Ryuga to kill him later.
- "The Reason You Suck" Speech: Kitaoka gives him a short one telling him that the more he tries to convince himself that he's a hero the less likely he's to become one. Considering Toujou's actions, he's right. Toujou did not took it well along with the defeat that came with it.
- Tears of Remorse: Sheds them when he kills his colleague and his mentor.
- Well-Intentioned Extremist: He makes himself out to be this, and to some extent wanting to kill Yui to end the Rider War counts. Unfortunately, in seeking to become a true hero, he easily took to the sacrificing part but didn't quite get into the saving part.
- Wipe the Floor with You: His Final Vent.
- Wolverine Claws: Dest Claws, which are his monster's forearms and bladed fingers.
- Mitsuru Sano (Kamen Rider Imperer)
Portrayed by: Takashi HyugaThere was once a young man who was disowned by his father. The father was a wealthy businessman and only wanted his son to go through the steps of a self-made man to insure that he would be a suitable and competent successor.Things did not quite go the way he planned.Mitsuru Sano is first seen working in a parking lot, pandering to the egos of men like his father to earn the odd tip, spending his free hours reminiscing for the life he once had. Chosen to become a Kamen Rider by Kanzaki, Sano contracted with the weak but massive herd of Gigazelle Mirror Monsters, becoming Kamen Rider Imperer. Like the Gigazelles under his command, Sano needed a herd of his own and began looking to ally himself with other Kamen Riders...for a price. Eventually, Sano decided to team up with Kagawa and Toujou to kill Yui, though that decision lead to nowhere when the latter betrayed and killed his mentor.Once again alone, Sano found himself without allies though a ray of hope was just around the corner. It was soon after Sano took an injured Toujou back to his home and nursed his former comrade when he received a call; his father had died and left the company in his hands. With his new status, Sano also came to know a lovely girl by the name of Yuri. What's more, Sano had come to develop a friendship with Toujou, a sentiment which the other man seemed to share. At last, Sano had what he always wanted: Happiness.But because he finally had what he wanted, there was no longer any reason for him to fight as a Kamen Rider. Unfortunately for Sano, the Rider War didn't work that way. A stern threat from Kanzaki and the leering, hungry glares of his Contracted Monsters was all that was needed for Sano to realize that the only way to survive was to win the War. Teaming up with Toujo, Sano attacked Shinji/Ryuki...until suddenly being betrayed by the man he had believed was his friend.Mortally wounded, Sano attempted to escape the battlefield but ended up instead in Kamen Rider Ouja's line of sight. Ouja dealt the fatal blow, shattering Sano's deck and leaving the man to dissolve in the Mirror World. His last moments were in the rain, screaming for help, gazing sadly into his world as his body was slowly eaten away.Meanwhile, in the real world, Yuri waited for Sano to return...
"I just wanted to be happy."
Tropes associated with Sano/Imperer:
- Anti-Hero: He won't do anything heroic without a fee, hence why Ren kicks him out since he demands an outrageous sum of money.
- Anti-Villain: He crosses into this when he's more ready to participate in the Rider War than before. He doesn't want to fight anymore, but at this point he no longer has a choice as he will be killed by his own monsters if he doesn't comply.
- The Beastmaster: His main Contract Monster is Gigazelle, however he is also accompanied by the Zelle archetypes (Megazelle, Negazelle, and Omegazelle).
- Beware the Nice Ones: After he became a president of his father's company, he became more aggressive in terms of personality.
- Bitch in Sheep's Clothing: Puts on a Nice Guy act to charm his fellow Riders in an attempt to get easy cash and an alliance to win the war. The few who do agree with him will have his loyalty...unless he makes an alliance with other Riders who give him a better deal.
- Briefcase Full of Money: Uses one on two different occasions to forge an alliance, first with Shinji and Ren, and then with Kitaoka. He's refused by the pair and the latter does not intend to do his part so Sano has the pay revoked.
- Broken Pedestal: When Sano first appears, Shinji was the first one who gave him a chance, even offering him a place to live...only for Sano to betray him in favor of helping Toujou in trying to kill Yui. The next time Sano comes to make an alliance, Shinji physically assaults him and throws him out, showing how deeply hurt he was at his betrayal. He verbally rejected him again when Sano attempted to bribe him and Ren into an alliance. Despite this, Shinji was later saddened upon learning of Sano's death.
- The Charmer: Attempts to do this with his fellow Riders. Only Shinji falls for it.
- Chronic Backstabbing Disorder: Betrays Shinji, the only Rider that was nice to him, twice because Toujou and his mentor gave him a better deal. He then becomes a victim of this when Toujou nearly kills him due to his belief of heroes killing their loved ones to become stronger.
- Death by Irony: He actually became happy during the war, having no more need for the wish. Unfortunately, he had to fight in order to survive, and was betrayed by Toujou, whom he thought was his best friend. He died to Asakura soon after.
- Driven to Suicide: According to him, during his talk with Shinji, he was so depressed over his lifestyle that he felt like dying every day until he was given the chance of being a Rider to become rich.
- Every Man Has His Price: He believes this wholeheartedly. He only intended to help as long as other Riders gave him a better payment, leading to his Chronic Backstabbing Disorder. After inheriting his father's fortune, he intends to 'bribe' them instead, leading to him being rejected out of principle or trying to be tricked.
- Finishing Move: Drive Divider note
- The Friend Nobody Likes: Ren kicks him out after hearing his fee, Kitaoka sends him to Asakura with the intention of getting him killed, Toujou only tolerates him due to his teacher hiring him, and Shinji no longer wants anything to do with him after being betrayed too many times. Subverted with Toujou after he saves him and then tragically double subverted when he fatally injures him under his belief that killing him will make him stronger and closer to becoming a hero.
- Meaningful Name: Imperer's name comes from the Latin root word, Impero, which means "to command," signifying his ability to command hordes of Monsters. Spelt alternately as Impaler, it signifies his penchant to fight with pointy weapons.
- Naïve Newcomer: Deconstructed due to him not being familiar with the risks of the Rider War. He takes the war as a chance to sell his services to other Riders for high payments, unaware that this is a conflict where the Riders will kill each other sooner or later. By the time he gets serious about killing Riders, starting with Shinji, it's mainly because Kanzaki tells him he can't retire or he will be killed by his own Monsters.
- Nice Guy: While he's fickle with his choice of allies, he's not a bad guy and will try to help the people he cares about.
- No Good Deed Goes Unpunished: He saved Toujou and took care of him even though when he started doing so he was still struggling to support himself, and it landed him with an ally that turned on him beat to the point where he was an easy kill for Asakura.
- Self-Made Man: Pretty much what Sano was intended to become when his father disowned him. Instead of that, things did not go as planned since he joined the Rider War and ended up signing his own death sentence.
- Sempai/Kohai: He's the last Rider to join the Rider War, making him the kohai to the surviving Riders. He lampshades this by calling them sempai during his initial attempt to get an alliance with them. Only Shinji fell for it, though this is can also be attributed to being a similar relationship with his boss and sempai at ORE, so he was happy to have a kohai Rider under his wing...at least before Sano betrayed him.
- Spoiled Brat: His father disowned him to prevent him from being this.
- Spoiled Sweet: His date with Yuri shows him to be a perfect choice for her. He's very much in love with her and does his best to keep her happy...which makes his death all the more sadder.
- This Is a Drill: Gazelle Stab, which is a sort of Power Fist with two long spiral horns.
- Took a Level in Badass: In terms of personality, he became smarter and more mature, figuring out that Kitaoka did not intend to ally with him after paying him and saving Yuri from a Monster.
- Took a Level in Jerkass: After inheriting all of his father's fortunes, he became more of a jerk that he wanted to win the Rider War so he can get his selfish desire of being a happy person.
- Weapon of Choice: His Spin Vent's Drill, Gazelle Stab.
- Yank the Dog's Chain: In the cruelest way possible. He actually gets what he wants without having to kill anyone, and would have dropped out of the Rider War and been no trouble... Then Kanzaki forced him to keep fighting, and it got him killed not long after.
- Zerg Rush: On the surface, his deck isn't very impressive, with only a rather awkward melee weapon and a mediocre mon, Gigazelle. However, Gigazelle itself is the leader of a herd of other Zelle monsters, which allows him to use Zerg Rush tactics with them.
- Miho Kirishima (Kamen Rider Femme) (Episode Final)
Portrayed by: Natsuki KatouThe first female Kamen Rider of the series, although it would not be until Kamen Rider Hibiki before a TV Female Rider appeared.A con-artist who seduced men for money, she joined the war for the same reason as Ren: to save the life of a loved one. For her it was her sister, whose body is preserved in a state of "cryogenic stasis" after being killed by Asakura.She meets Shinji after running from a man she tried to swindle, and the two develop an awkward romantic relationship. Though they often argued with each other (primarily over the Rider War and her loose sense of morality), her small kindnesses and flirtations served to confuse Shinji as he tried to figure out her character, complicated by her attempt to pickpocket his Advent Deck.As Femme, she is able to hold her own against Mirror Monsters but is outmatched in combat ability against other Riders. After Kanzaki imposes a three-day time limit to the Rider War, she attempts to kill Asakura and avenge her sister, but finds herself helplessly outmatched. She is almost killed when she is saved by the dark Ryuga, whom she mistakes for Ryuki in the dim light.The next day she takes Shinji out to dinner as thanks, something that confuses him even further. However, their date is cut short when Ryuga emerges from the Mirror World to attack her. They transform to battle in the Mirror World, and she is mortally wounded by Ryuga's overwhelming power, only saved from total annihilation by the real Ryuki. They return to the real world and Shinji walks her home, leaving with assurances from Miho that her injuries are not as severe as he suspected. However, after he leaves she collapses to the pavement and dies, her body ignored by the thousands of pedestrians who walked the streets the next day.
Tropes associated with Miho/Femme:
- Action Girl: The only female Rider in the series.
- Cool Sword: Blanc Visor, a Royal Rapier like Knight's.
- Death by Irony: Tried to con Shinji, was saved by Ryuga and mistook him for Shinji thus falling in love with him, was ACTUALLY saved by Shinji FROM Ryuga and fell in love with him for real... And then died from her wounds shortly after.
- Distaff Counterpart: Of Knight, being based on a winged animal while using a rapier Ride Vendor when not using a large bladed weapon.
- Double Weapon: Wing Slasher, which is twoblades on a stick
- Finishing Move: Misty Slash note
- Foil: To Ren. While he's primarily black and blue, Miho's white and black. Similarly, while Ren's combat style revolves around down and dirty one on one combat, Miho's focuses on graceful illusions and crowd control. Both of them even become close to the resident Idiot Hero Shinji.
- Gold Digger: At first seduced men (including Shinji) for money. Then she falls in love with Shinji after Ryuga saves her...and dies soon after.
- Luckily, My Shield Will Protect Me: Wing Shield
- Rescue Romance: Falls in love with Shinji because she thought he saved her from Asakura. It was actually Ryuga. Falls in love with him for real after Shinji saves her from Ryuga... then dies right after.
- Revenge: Killing Asakura was her main objective in the Rider War.
- The Smurfette Principle: The only female rider in the series.
- Itsurou Takamizawa (Kamen Rider Verde) (13 Riders)
Portrayed by: Arthur KurodaThe thirty-eight year old head of the Takamizawa Group, Takamizawa is a rich and respected businessman who keeps his true megalomania hidden to all but the other Kamen Riders. He saw the Rider War as an allegory for human society: individuals struggling to make their dreams come true at the expense of others. His reason for joining the Rider War is simple: power. If he won, he would use the Prize to rule the world. His Contract Monster, the chameleon Monster Biogreeza, grants him numerous powers of deception which he uses to ruthless effect in the 13 Riders special.A charismatic man, he convinces Kitaoka and Shibaura to team up with him against the naive Shinji, whose attempts to stop the Rider War he viewed as a threat to his plans. Though he kills Raia (by tricking him into lowering his guard) and mortally wounds Ren, he is unable to defend himself against Ren's last Final Vent attack and dies.
"Every human being is a Rider."
- Ambition Is Evil: He wants to rule over the world.
- Big Bad: Of the 13 Riders special since him gathering the surviving Riders to kill Shinji and Ren is what starts the climax.
- Corrupt Corporate Executive: He may be a charismatic leader of his own corporation, but on the inside, he's a megalomaniac who seeks power in order to rule the world.
- Costume Copycat: His Copy Vent (apparently different from Raia's card of the same name, which copied weapons).
- Death by Irony: Gathers the surviving Riders to kill Ren and Shinji since the latter's idealism is a threat to the Rider War and the former betraying the group to protect him puts a risk to his plans. He mortally wounds Ren while attempting to kill Shinji with his Final Vent, only for Ren to kill him with his own Final Vent. It's ironically makes him the first victim of his master plan, which was to kill Ren and Shinji so that the Rider War can continue.
- Finishing Move: Death Punish note
- Intergenerational Friendship: With Jun, who's one of the youngest Riders while he's the oldest.
- Invisibility - His Clear Vent. Comes with a chameleon-based Contract Monster.
- Killer Yo-Yo: Bio-Winder, his Weapon of Choice.
- Villainous Friendship: Considering that in the original series, Jun intended to make battle royale between all Riders and Itsurou pretty much united all Riders in a the same spot to fight, it an be assumed that Jun admires him for his charisma and for making the Rider War more interesting.
- Villain with Good Publicity: He is well-respected by his own company and Jun.
- Wrestler in All of Us: His Final Vent ends with a piledriver.
- Dark Shinji (Kamen Rider Ryuga) (Episode Final)
Portrayed by: Takamasa SugaDark Shinji/Ryuga is the Mirror World Rider, born when a young Yui Kanzaki wished for a playmate in the Mirror World and created it in the image of the mystery boy that she had befriended: Shinji Kido. Where Shinji is kind and compassionate, Ryuga is cruel, manipulative and utterly merciless. His Rider self is a soulless reflection of Ryuki, as is his contract Monster Dragblacker.As a denizen of the Mirror World, Ryuga followed the opposite rules from regular Riders: he could pass into the real world for a time, but after a while he would begin to dissolve and had to return. He wished to absorb Shinji to eliminate this weakness and become a real person, not simply an illusion in the mirror. He has no need for a reflective surface to summon his V-Buckle, as he himself is a living conduit to the Mirror World's energies.He kills Ouja and Femme, and succeeds in absorbing Shinji by convincing the poor boy that it was what Yui wanted. He would have killed Knight, if not for Shinji realizing the truth and rejecting Ryuga. This forces a final confrontation where their Final Vents clash. Ryuga is the loser in this fight: even if they were equals once, Shinji's rediscovered resolve was too much for Ryuga to handle.
"I am no longer an illusion in the mirror! I exist! As the strongest Kamen Rider."
Tropes associated with Ryuga:
- Artifact of Doom: The S.I.C. story World of If shows that Shinji became Ryuga when he discarded the Ryuki deck over the Ryuga deck on the last days of the Rider War.
- Become a Real Boy: His wish was to fuse with Shinji and take control of his body.
- Cool Sword: Drag Saber
- Death by Irony: His ultimate goal was to absorb Shinji and become one. He's lost forever when Shinji absorbs him.
- Evil Sounds Deep: His Visor has a noticeably deeper voice than others when reading cards.
- Evil Twin: He's Shinji's reflection so he looks like him.
- Subverted in a S.I.C story where Ryuga is the spirit of Shinji's older twin brother, who was the opposite of Shinji in terms of personality, but otherwise loved his brother. He actually wins the Rider War and uses the wish to revive all the victims since that's what Shinji would have wanted.
- Finishing Move: Dragon Rider Kick note
- Luckily, My Shield Will Protect Me: Drag Shield.
- Manipulative Bastard: Makes Miho think that he's Shinji and takes her out on a date so that he can kill her while she has her guard down.
- Mirror Self: Fittingly enough, Dark Shinji is Shinji's Mirror World counterpart.
- Paint It Black: He's Ryuki but painted black instead of red.
- Pet the Dog: Played with Yui when she was saddened over Shinji breaking his promise of playing with her. Although this can be attributed to him being a Mirror World creation, which are all shown to be loyal to Yui throughout the series. It is unknown how true this remains in adulthood when Shinji accused him of trying to manipulate him when he suggested using the wish of the Rider War to resurrect a dead Yui in order to trick him into merging with him.
- Weapon of Choice: Just as Ryuga is a dark version of Ryuki, his weapons are black versions of Ryuki's weapons.
- The Worf Effect - Within minutes of his introduction, he effortlessly defeats Ouja.
- Kamen Rider Odin
Voiced by: Tsuyoshi KoyamaThe thirteenth Rider, one who was only supposed to be fought by the Rider who defeated the other eleven. As Kanzaki's personal trump card, Odin was ludicrously overpowered to the point of outright cheating: he was so fast no-one could touch him, could steal other Riders' equipment via Steal Vent, possessed the third Survive card (with a power rating of Infinity!, though he never even had to use it) and had the most powerful Mirror Monster Goldphoenix contracted to him. Odin's responsibilities are two-fold: to protect Yui Kanzaki, and to defeat the final Rider and win the Prize on behalf of Kanzaki.His most important ability is the Time Vent card, which rewinds the Rider War back to the start and erases the memories of all involved. Kanzaki would use this ability over and over again, each time making a change in order to edge closer to the conclusion that he wanted. Only Shinji has a resistance to the memory-erasure, as he was never one of Kanzaki's chosen Riders.Despite the Foreshadowing to the contrary, Odin is not Kanzaki. Odin is an anonymous person that Kanzaki gave the Odin Advent Deck to. But unlike other Advent Decks, the Odin Deck erases the identity of the person who uses it, leaving only Kanzaki's puppet and stand-in who can interact with the real world in ways that Kanzaki- as a being of the Mirror World- cannot. This made him even more an unfair edge for Kanzaki, because if Odin was killed he could replace him. During the course of the series, Kanzaki goes through at least three Odins: the first is killed by Knight in order to motivate Ren into killing the rest of the Riders; the second dies at the hands of Knight and Ryuki when Odin attempts to stop them; the third confronts Knight at the climax of the Rider War but is killed by Kanzaki himself, after the latter realizes the futility of the War.
"It is none of your concern. Continue to fight. Only the final Rider may face me."
Tropes associated with Odin:
- Armor-Piercing Slap: It's strong enough to knock over a frigging truck.
- Awesome, but Impractical: His Final Vent, Eternal Chaos. Eternal Chaos has way more power than everyone else's Final Vent (even Survive Ryuki and Knight's Final Vent has less power than Eternal Chaos), but it can kill himself if he's not careful (as his American counterpart Wrath demonstrates in the only time Wrath uses the Final Vent).
- Badass Arm-Fold: His default pose, more or less.
- Bigger Bad: The 13 Riders special has him destroy Shinji's deck, intending for him to dissolve in the Mirror World until Ren gave him his Advent Deck. One of the endings has Odin laugh at Shinji when it's revealed that he didn't stop the Rider War by destroying the core mirror in a Downer Ending.
- Bling of War: His armor, Visor, and weapons are all golden.
- Brainwashed - The person acting as the host for Odin.
- Combat Pragmatist: While not a skilled fighter, he does take full advantage of his teleportation power and spams the hell out of it.
- The Computer Is a Cheating Bastard: Seriously, could Kanzaki have made Odin any more unfair to fight against?
- Cool Sword: Gold Saber, he pull Dual Wielding in the finale.
- Curb-Stomp Battle: Every fight he takes part in. Ren beating the first one only happened because he got careless and left himself open, and the second because he got distracted and allowed Shinji to hold him in place for Ren's Finishing Move. Odin would've killed Ren the third time around, if not for the fact that at literally the last second Kanzaki changed his mind.
- Death by Irony: Specifically made to win the Rider War and to loop time repeatedly in order to manipulate its outcome, Odin is destroyed when Kanzaki realizes the whole war is pointless.
- Dragon-in-Chief: To Kanzaki. His plans need him around to succeed and he's the strongest enemy the other riders face.
- The Faceless: His identity is never seen, because it's actually not important—-Odin is a vessel for Kanzaki's will and his hosts are always brainwashed.
- Finishing Move: Eternal Chaos note
- Flash Step: A big part of why fighting him is so futile; he moves out the way of every attack used on him (you can literally count the number times somebody hit him on one handnote note ) and can attack his enemies from various angles too quickly for them to respond.
- Hoist by His Own Petard: His Final Vent has a possibility to do so.
- The Juggernaut: Ren and Shinji in their Surive forms couldn't even slow him down, and that incarnation only died after a lot more teamwork and a bit of sheer luck when he got distracted by Yui screaming.
- Large Ham: He practically shouts all his lines
- Lightning Bruiser: He's strong enough to send a speeding truck off its course and can move too fast for his enemies to even touch him. He's no slouch for taking hits either, one of the few times he was hit (a punch from Shinji's Strike Vent) was more a shock to him that Shinji hit him than anything else.
- Luckily, My Shield Will Protect Me: Gold Shield
- Meaningful Name: He's named after a god, which rings true considering just how overpowered he can be.
- Ominous Latin Chanting: His entrance during his debut episode.
- Purposely Overpowered: Kanzaki has no interest in fighting fair.
- Reset Button: Time Vent, which turns time back to however far Kanzaki wants and has been used an unspecified number of times by the time the show starts. Two of the resulting timelines are seen in the events of the TV Special and the Movie, and the main series is the last.
- Suicide Attack: Though Odin's Final Vent is not shown in Ryuki, Dragon Knight reveals that Odin's Final Vent is essentially this, as Wrath (Odin's counterpart) gets vented/killed immediately after using the Final Vent.
- Super Mode: Survive Form, using the Survive Mugen card. He's never needed to use.
- 13 Is Unlucky: Unlucky to face.
- Unskilled, but Strong: Since Odin is just a random person acting as Kanzaki's puppet, he wins by means his overwhelming power and Flash Step abilities rather than actual skills. Of course, given his ridiculous power, he can afford to be this way.
- Hideyuki Kagawa (Alternative Zero)
Portrayed by: Satoshi JinboOnce a mentor to Shirou Kanzaki, Kagawa accidentally glimpsed notes made by his student concerning the Mirror World and due to his Photographic Memory, was able to recall every detail of Kanzaki's plans. When his student, Satoru Toujou became Kamen Rider Tiger, Kagawa enlisted the young man and one of Kanzaki's former colleagues, Hajime Nakamura, to close the Mirror World, on the pretense that it was the heroic thing to do. Living by the mantra 'One Life To Save Ten', Kagawa attempted to assassinate Yui to render Kanzaki's plans redundant but would find the likes of Shinji and Ren a constant thorn in his side.Eventually, when at a hair's breadth away from fulfilling his mission, Kagawa was betrayed and killed by Toujou, his body dissolving from the arms of his treacherous student.
"To sacrifice one life in order to save ten: that is the meaning of a true hero."
Tropes associated with Kagawa:
- Blessed with Suck: Possibly more so than anyone. If not for his Photographic Memory, he would have never known about the Rider war. He even stated himself that it causes him problems. He was right.
- Cool Sword: Slash Dagger.
- Evil Counterpart / Evil Knockoff: Alternative's visor speaks with a female voice instead of a male one, its belt spins vertically instead of horizontally when it appears, and its Advent Cards are swiped across the visor instead of being inserted into them. Alternative's Advent Cards are also laid out lengthwise (name on the right, image in center, stats on left) instead of the regular heightwise (name on top, image in center, stats on bottom).
- Finishing Move: Dead End note
- Hero Antagonist: He is genuinely good person trying to stop a terrible event that over the course of the series claims dozens of innocent lives, it's just that his willing to take more extreme measures to do so.
- Hostage For Macguffin: Kanzaki pulls this on him, threatening to set a Mirror Monster on his family unless he gives up the Alternative deck. He refuses.
- Hoist by His Own Petard: His teachings of "sacrifice one life for ten" to Tojo ultimately results in the latter killing him.
- Horrible Judge of Character: Kept Toujou around even after the latter killed one of their allies. Although he may not have had much of a choice in the matter.
- The Needs of the Many: An avid believer.
- Photographic Memory: He says whenever he looks at something, it sticks in his head. He took one short look at Kanzaki's file, and remembered enough to create fake Advent Decks and hypotheses to seal the Mirror World.
- Reasonable Authority Figure: He's the leader of the three Riders fighting to seal the Mirror World. For all his unfettered tendencies, he is willing to reveal their secrets to those he thinks they can trust, and is the most altruistic of the three, unwilling to kill unless necessary and having no ulterior motives for sealing the Mirror World.
- In fact, despite not agreeing with Shinji, he genuinely doesn't dislike him, especially after Shinji saves his own family. Kagawa tries to use them as an object lesson as to why his student should stop going around killing for no reason, but it doesn't stick.
- Super Speed: Accel Vent
- The Unfettered: He's willing to dirty his hands and even sacrifice his own family to stop the Rider War. However, he draws the line at needlessly killing people, something which his student unfortunately had a penchant for doing.
- Well-Intentioned Extremist: He's willing to kill Yui to end the Rider War. And is even willing to sacrifice his family, even though it grieved him to do so. Unlike his student, he is entirely aware that killing people is wrong, and that taking human lives is a burden you'll have on your head for the rest of your life.
- Wrong Genre Savvy: His assumption that Yui is the key to ending the Rider War. He's right, but because she's the only one that can convince Kanzaki to stop it, her death will do nothing.
- Hajime Nakamura (Alternative)
Portrayed by: Junichi MizunoA former colleague of Shirou Kanzaki at the Ejima Lab. He was away when Kanzaki conducted his experiments, thus he became the only survivor from the lab's staff. Although Yui and Reiko each ask him about his involvement, he vehemently refuses to answer them. Later, he is discovered to have teamed up with Hideyuki Kagawa and Satoru Toujou, seeking to close Mirror World by killing Yui. After Shinji thwarts his attempts, he is ambushed by Toujou, showing that the latter would not be afraid to betray his allies to fulfill his twisted morals.
Tropes associated with Nakamura:
- Shirou Kanzaki
Portrayed by: Kenzaburo KikuchiThe Big Bad and mastermind behind the Rider War. Kanzaki is the creator of the Advent Decks, chooses who to give them to and subconsciously encourages the wielders to fight. He is a psuedo-being of the Mirror World, living in the Mirror World and able to travel through reflections but unable to tangibly interact with the real world in the way that Mirror Monsters can. He can also control the Mirror Monsters, sending them to fight specific Riders and provoking conflict. He promises to offer power great enough to grant a single wish to the last remaining Rider: this is a half-truth, as his plan is to have Odin kill the last Rider and take the power for himself.For the majority of the series, Kanzaki's motives are wrapped in mystery. But despite his inhuman demeanour and powers, his motives are far too human: to save the life of his sister Yui. For it was his decision as a child- an all-too-human decision- that led to the Mirror World Yui replacing the life of his dead sister; a decision he made because he could not stand to lose the one thing in his life that brought him hope. And when he was forcefully separated from her, taken to America by relatives, he screamed and pleaded not to go.From that point on he dedicated his existence to finding a way to save her. He studied the Mirror World, discovering how to harness its power and extend Yui's life. He even discovered how to use it to manipulative time itself, and became a being of the Mirror World.But Kanzaki couldn't get the outcome he wanted. After every failure, he would rewind time and do things differently, making small changes in the hope that it would edge him closer to his desired outcome. But no matter how many times he ran the Rider War, no matter how many advantages he gave himself or how many changes he made, he could never do it. And there were some things that he couldn't change at all: Shinji always became a Rider, and would always be an unwanted presence in Kanzaki's plan. And Yui, upon finding out the purpose of the Rider War, would always reject the new life he had worked so hard to give her.It is unknown how many times Kanzaki rewound time, changed history and ran the Rider War. But distortions were beginning to appear in time itself. For example, there were records showing that Kanzaki had died in America at the same time he was studying in Japan. In the end, he finally accepts the bitter truth: that Yui would never accept the new life, that all his efforts were misguided. So once again he rewinds time to the moment of Yui's death, but this time he enters the Mirror World to be alongside her Mirror World self forever. Yui is never reborn, the Mirror World remains closed, and the Rider War never occurs in the first place.
Tropes associated with Kanzaki:
- Berserk Button: Threatening Yui.
- Deal with the Devil: His M.O. towards his chosen Riders in order to further his own motives.
- Freak-Out: After Yui kills herself in The Movie, Shiro has a freakout so huge, it breaks the barriers between the real world and the Mirror World, shattering glass for seemingly miles around.
- Invincible Villain: Even though the Rider War doesn't go entirely the way he wants it to, there is NOTHING that any of the riders can do against him. He's a ghost, so they can't attack him, he controls the single most powerful Rider, so should they even try they're almost certainly going to fail. It isn't until the finale where it's even hinted that things won't go the way he planned them.
- Knight Templar Big Brother: He tries to save his sister Yui from her impending death by any means.
- Morality Pet: Deconstructed. Yui is the only thing that has any meaning in Shiro's life, so he's willing to sacrifice anything and everything for her.
- This leads to some cases of shortsightedness when it comes to her. When he learned of the plots of the Alternatives, people who wanted to seal the Mirror World by killing Yui, he gave the Survive Rekka to Shinji to protect her. Shinji, the Rider who's the BIGGEST obstacle to people killing each other, now has the power to survive even greater odds.
- Non-Action Big Bad: Since he has no physical body after he became a Mirror World being, he relies on sending Mirror Monsters, other Riders and Odin to do his dirty work.
- Not So Stoic: Towards the finale, leading up to his Villainous Breakdown.
- Reality Warper: Not only did he and Yui somehow create the Mirror World and gain the power to control Mirror Monsters and grant any wish, he created the Advent Decks, and one of those cards can even go back in time.
- Reset Button: Time Vent, via Odin, which resets the whole Rider War. He's willing to use this for many reasons, ranging from Yui dying to a vase of water accidentally spilling and ruining one of Yui's childhood paintings.
- Stealth Hi/Bye: Constantly doing this. He'll appear, briefly speak to a Rider, and leave without a trace.
- Villainous Breakdown - Fantastically achieved in the last two episodes when Yui dies. When his voice loses the echo effect it almost always has, you know he's reached his breaking point.
- Yandere: A very extreme one. He ignores most of Yui's pleas to stop the Rider War, justifying his actions saying she doesn't understand the pain they both went through as a result of her death, and he's not entirely making that up. But even when she opposes him, it still takes him time to come to his senses. By time, we mean several Rider Wars, spanning a period of several years worth of alternate timelines.
- Well-Intentioned Extremist: Very extreme, he lets the Mirror Monsters run wild and kill innocent people by the masses and manipulate the lives of everybody involved in the Rider War, but all to save his little sister.
- Yui Kanzaki
Portrayed by: Ayano SugiyamaAs a young girl, Yui Kanzaki was cursed with the power to see the Mirror World and its monstrous residents; an ability which made her the victim of merciless taunts by skeptical schoolmates. Added to that an abusive family-life and it was little wonder that Yui gravitated so closely to her brother, Shiro. Together, they formed the foundations of the Mirror World, creating the Mirror Monsters to act as their guardians but then...Yui died.Unable to accept her death, Shiro made a deal with Yui's Mirror World self to resurrect her, although she would disappear forever on the day of her 20th birthday. The resulting breach in realities as the Mirror World-Yui merged with the real Yui caused a fire in the Kanzaki mansion, killing both their parents. Yui was adopted by her grandmother Sanako while Shiro was taken in by a different set of relatives and sent to America.For years, Yui lived ignorant of her death and would likely have remained so if not for the Rider War. Refusing to believe that her brother would be so cruel as to set twelve individuals against each other, she begged for answers from her now estranged brother. Eventually, realizing the truth as her body slowly began to crumble away, Yui made a final desperate plea for Shiro to stop the Rider War.She would succeed, as on the verge of allowing Kamen Rider Odin to become the final Rider, Shiro finally had a change of heart and destroyed his own minion. Shiro then reversed time and allowed himself to die alongside Yui, entering the Mirror World with her alongside their Mirror World selves to live the rest of eternity in peace.
Tropes associated with Yui:
- Apocalypse Maiden - Professor Kagawa believes that Yui is the key to the Mirror World, and that killing her will make it all go away. He is in fact wrong, as seen when she dies in both the series and in The Movie and the Mirror World and all its monsters continue existing.
- Driven to Suicide: In The Movie's ending, she kills herself. Her brother doesn't take this well...
- Tomato in the Mirror: Literatary as well, she actually are Yui mirror coutenpart as real Yui died,
- Gorou Yura
Portrayed by: Tomohisa YugeGorou is the manservant of Shuichi Kitaoka, and utterly devoted to the man. He's a talented cook and martial artist, and for a brief moment it was hinted that he was Zolda. He also has an odd habit of whistling, and admires anyone who has an equally good whistle. Gorou knows about Kitaoka's double-life as Zolda, and it causes him great pain to think that his master is fighting for his life every time he transforms.Gorou's dedication to Kitaoka came from a sense of guilt: Kitaoka had defended Gorou in court against a false charge instead of attending a medical examination that could have detected his cancer and saved his life. Kitaoka holds no grudge against Gorou, but the young man feels beholden to Kitaoka. At one point, Gorou nearly murders Asakura to protect his master. But Kitaoka stops him, knowing that the act would have shattered Gorou emotionally and gently telling him that it was not his duty to fight his battles for him.Sadly, it was the very act of fighting one of Kitaoka's battles for him that led to Gorou's death. Having refined his abilities to the level of a master chef, Gorou could have left and lived his own life. But instead, with Kitaoka determined to finish things with Asakura but unable to because of his rapidly failing health, Gorou takes the Zolda Deck and goes in his place. The Mirror World is where Gorou meets his end.
"You... have a good whistle."
Tropes associated with Gorou:
- Badass Normal: So much so that Shinji initially assumes he's Zolda.
- Friend to All Children: Unlike his master, Goro is nice to children, even giving them candy.
- Hypercompetent Sidekick: He's Kitaoka's personal butler, secretary, bodyguard, photographer, driver, cook , errand boy, and his best friend.
- I Owe You My Life: Kitaoka saved him from going to jail so now he's going to serve him forever.
- It's All My Fault: He blames himself for Kitaoka's disease (and probably for his subsequent involvement in the Rider War) because Kitaoka defended him in a case of petty assault rather than having a medical checkup that could have detected his disease earlier and saved his life.
- Morality Pet: He brings out the best in Kitaoka, although it's only around him as gratitude for his services.
- Odd Friendship: With Shinji after some awkward Pet the Dog moments.
- Pet the Dog: Gives a girl candy when Kitaoka refuses to help her and politely praises Shinji on his Gyoza recipe before timidly asking for it, which cements his friendship with him.
- Supreme Chef: Personally cooks for Kitaoka, who constantly praises the quality of his meals. Asakura also takes delight in eating any dish that Goro cooks every time that he ransacks Kitaoka's house in his attempts to fight him.
- Undying Loyalty: To Kitaoka.
- Unknown Rival: To Asakura, whose first attempt to kill Kitaoka he thwarted since the former was still not used to using his Rider powers. Afterwards, Asakura is quite dismissive of Goro, pretty much ignoring him or using his Mirror Monster to capture him while Goro assumes a fighting stance or tries to run him over with his car.
- Taken Up to Eleven in the last episode, where he takes up Kitaoka's identity as Zolda to fight Asakura in his master's place. This time around, Asakura takes him seriously and Goro finally gets to lay the hurt on the man that has been trying to hurt his master throughout the series. Despite giving Asakura a good fight, Goro dies and Asakura is Driven to Suicide out of sheer dissatisfaction, showing that he did not think much of Goro despite the challenging fight if that didn't mean killing Kitaoka.
