Series / Kamen Rider Ryuki
"Those who do not fight will not survive!"
The 2002-2003 entry in the Kamen Rider
franchise, and third in the Heisei Era.
Shinji Kido is a young, highly excitable Intrepid Reporter
for the online news website ORE Journal. Whilst investigating a series of seemingly random disappearances, he stumbles across a mysterious card deck
at the home of one of the victims. After picking it up, he finds that he is able to see hostile monsters living inside of reflective surfaces
, and is soon sucked through into the Mirror World: a parallel universe
that serves as their home.
He soon meets up with two people involved with this strange otherworld: Yui Kanzaki, a young girl looking for her missing brother, and her partner Ren Akiyama, a longcoat-wearing
, Harley-riding stoic Badass
who has a card deck of his own and can use it to transform into Kamen Rider Knight. Despite the warnings of Ren and Yui, Shinji decides to make a contract with one of the Mirror Monsters to gain its power and fight as Kamen Rider Ryuki to protect the innocent. However, he has unwittingly entered into something far greater: the Rider War.
Thirteen Advent Card decks have been created for thirteen Kamen Riders, and There Can Be Only One
. The mastermind behind the Rider War is Shirou Kanzaki, Yui's missing brother, and he offers to grant a single wish to the last Rider standing. Shinji is determined to stop the in-fighting between the Riders and concentrate on eliminating the threat of the Mirror Monsters, but Ren is equally determined to have his wish granted, and he isn't the only one. Ideals and friendships clash on and off the battlefield as the pressure of the war grows and the Riders are eliminated one by one.
The series consists of the following installments:
Partnered with the Super Sentai
show Ninpuu Sentai Hurricaneger
after initially airing alongside the final episodes of Hyakujuu Sentai Gaoranger
in what would later be known as the Super Hero Time
The series was adapted for Western audiences in 2009 as Kamen Rider Dragon Knight
This series contains examples of:
- Abusive Parents: Yui and Shiro had parents who locked them up in the attic for extended periods of time and were neglectful to notice that Yui got sick and died. They'd eventually become the reason why The Rider War began.
- All Just a Dream - The Hyper Battle Video.
- Alternate Timeline - The TV series, the 13 Riders special and The Movie all exist in their own timelines. This is a result of Shirou Kanzaki's overuse of the Reset Button. The TV series is actually his final attempt to do it again.
- Animal Motifs: The contracted Mirror Monsters, and by extension, the Riders they contract with.
- Antagonist in Mourning: When Asakura discovers that he has failed to kill his nemesis, Kitaoka, it prompts him to charge out in a suicidal rage and get killed by the police.
- Anyone Can Die. And does.
- Awesome, but Impractical: Zolda and Tiger's Final Vents. For the former, it's Game Breaker status is mitigated by a long build-up time that leaves him wide open to attack, and the fact that despite being able to wipe out large numbers in one go, he never manages to kill anyone with it. The one character who takes it head on is badly injured, but survives... and is killed by another rider moments later. For the latter, it's demonstrated that the gap between when Destwilder attacks and Tiger finishes the enemy off is a wide enough period of time for an aware rider to escape and survive (as both Asakura and Kitaoka managed to do).
- Some of the Visors used by the Riders. While some are dual purpose weapons and card scanners or are easily accessed, Ouja and Odin have large staffs that look cool but they don't use at all in combat and must we pulled out of Hammerspace just to be used. By contrast, Ryuki just slides a card into a gauntlet on his arm and done.
- Ouja's use of multiple Monsters gives him both impressive power and a more varied arsenal than most other Riders... but it means he has three monsters to feed whereas everyone else only has to take care of one—-on top of which, two of those monsters kinda hate him because he stole them after having killed their original Riders.
- Back from the Dead - Yui Kanzaki, and this is the driving force behind the entire story.
- Bad Guys Do the Dirty Work - In a show where There Can Only Be One and you have someone who doesn't wish to fight the other Riders as your main character, that's when the resident Anti-Hero comes in, though when it comes to killing them, then you have the psychopathic Blood Knight and a Heroic Wannabe to fall upon.
- Big Damn Heroes - Shinji gets a few, including one in the first few episodes where he saves Ren from Volcancer after it turns on and consumes Scissors.
- BFG - Zolda loves these, as he has two: two shoulder-mounted rocket launchers and an artillery cannon that's three times as long as he is high◊.
- BFS - Kamen Rider Knight's Wing Lancer is almost six feet long.
- Alternative's sword also qualifies.
- Bittersweet Ending - The real ending has Shirou Kanzaki pressing the Reset Button again, only this time, he and Yui die in that reality
- Blessed with Suck - Becoming a Kamen Rider means you gain cool powers, but you're also bound to fighting the other Riders and monsters, and if you stop fighting, your contract monster eventually eats you.
- "Blind Idiot" Translation: See Reverse Funny Aneurysm below. A full list about halfway down this page.
- Bolivian Army Ending - The ending of The Movie, and one of the possible endings of the Special.
- Bond Creatures - The Mirror Monsters that are neither monsters of the week nor under Kanzaki's direct control.
- Boring but Practical: Ryuki's Advent Deck. Unlike Knight, Raia, and Odin, it has no special cards at first, making it seem a bit dull. However, it's got shields, a long range fire blaster, a sword, and can let him summon a dragon, meaning that he's got weaponry for any sitiuation.
- Brainwashed - The Odin Advent Deck turns the user into Kanzaki's puppet.
- Breakable Weapons - Shinji's weapon in his "Blank" form (before he becomes Ryuki) is a pathetic thing that breaks after one hit.
- Captain Ersatz - Ren Akiyama/Kamen Rider Knight bears more than a few thematic resemblances to a certain other Dark Knight. Not that we're complaining.
- Cameo - Several members of Kamen Rider Agito's cast, including three of the Riders, appear in Episode Final.
- Canon Foreigner - Kamen Rider Abyss, who is exclusive to Kamen Rider Decade.
- Card Battle Game - Each Rider uses Advent Cards to activate his/her powers.
- Cardboard Prison - Asakura breaks out of jail multiple times for one reason or another, the first by traveling the through the Mirror World, the second by hiding the Contract Card for Metalgelas under his shirt when Kitoaka had the police take the rest, and the third by taking advantage of the sympathy a Genre Blind lawyer had for him.
- Cassandra Truth - Episode 28 has Shinji reappearing in past episodes, and all his attempts to warn everybody of the future are promptly ignored.
- Chronic Backstabbing Disorder - Toujou, Sano.
- Clothes Make the Superman: The wielders of the Rider Decks were chosen by Kanzaki Shiro, but they can be actually be used by anyone, as noted in the following examples:
- Shinji and Miyuki were not the original owners of their Rider Decks (which is actually an important plot point in Shinji's case). Shinji found the Ryuki deck after its original owner disappeared (presumably killed), whereas Miyuki inherited the Raia deck from his friend Yuichi after Yuichi was eaten by his contract beast. We see the original Ryuki in the 13 Riders TV special.
- After Kitaoka dies from a terminal illness in the finale, his servant Goro inherits the Zolda deck and challenges Asakura instead.
- The 13 Riders special ends with Ren dying and Shinji becoming the new Knight.
- Cool Sword - Ryuki, Knight, Ohja, Odin, Femme, Ryuga and Alternative each have one of these.
- Cosmic Horror Story: Averted. It looks very much like one at a glance, but the Rider War happened because a human, Kanzaki, made it happen. And for all the power he has, controlling the Mirror Beasts and the strongest Rider, his desires are just as much out of his reach as the rest of the casts.
- Covers Always Lie: In a combination of Bait and Switch and Never Trust a Trailer, the ending of episode 6 shows a shadowed figure wearing gloves taking out a Card Deck and transforming into Zolda, and the next-episode preview showing an unkempt bearded man wearing gloves doing a transformation pose. And at the start of the next episode, said man is shown walking away after Zolda fights a Monster... only for the next time that Zolda's Card Deck appears on-screen be when Kitoaka takes it out of his pocket.
- Darker and Edgier - Even within the Kamen Rider franchise as a whole, Ryuki is one of the darker entries, holding the highest body count of major characters in the whole franchise.
- And though fairly passe now, it was the first series that featured officially recognized 'evil' Kamen Riders (as opposed to Rider-like villains, such as the Shocker Riders and Shadow Moon, that didn't carry the "Kamen Rider" title).
- Deadly Game - Jun Shibaura/Kamen Rider Gai, who creates a video game based on the Rider War that soon spills over into real life.
- Deconstruction - of the ensemble Henshin Hero genre. See Five-Man Band below for one example.
- The series also deconstructs competitive fighting games and fighting game tournaments. Competitive Balance can get shot down real quick through dirty tactics and said game is fixed, with the host of the tournament having full control of the resident Game Breaker.
- It also deconstructs the Mons. Let's say you form a contract with one of them. Great! Now you can use their body parts as weapons to fight people who also use their monster's body parts to fight. You also have to fight other monsters to give your monster something to eat, unless you come to the conclusion that you can simply feed people to your monster (as Scissors and Ohja prove). If you don't fight the monsters? Then your monster gets hungry and decides to eat you. It also happens if you don't even want to fight or you're forced not to. Or even if your Advent Card (the one you use to sic your monster on other people) or Deck (the thing you use to transform) get broken. And it's not like there's a good chance your monster will even be loyal to you anyways. Especially if you have two other monsters working for you that you snagged off their dead masters, or you just happened to luck out and contract a monster that comes in herds. Wow.
- There's also a deconstruction of the Let's You and Him Fight and Conflict Ball tropes. Whereas in other Kamen Rider shows, they fight each other for different reasons or misunderstandings, here they have no choice but to fight each other. The entire point of the show is to stop the fighting. This might be an Unbuilt Trope though, since the two tropes didn't have a massive occurrence until right after this show.
- Phlebotinum Rebel, one of the central tropes of the Kamen Rider franchise, is also deconstructed, as attempting to use the Advent Decks against Shirou and his aims is doomed from the outset due to the fact that he reserved the most powerful Advent Deck for his own use by perfectly brainwashed drones. Not to mention that he can just time travel if things get too hairy.
- Thirteen Riders took this trope to hell. Not everyone supports Shinji's attempts to stop the fighting and it resulted in all the remaining riders (about 9 of them) teaming up to kill him and Ren. And in the alternate ending, where he did stop the fighting, Shiro simply resets time and has the fight happen all over again.
- Since Kazuya Taki from the first series, up until Makoto Hikawa, most audiences would assume that cop is our hero's best friend. Then Masashi Sudoh reminds us that bad cops exist.
- Then there's the deconstruction of the Secret Identity and Living a Double Life, but only for poor Shinji. His time as a Rider constantly interferes with his work when he has to go off save people instead of investigate cases or write articles, and because his coworkers have no idea his pay is docked and he's only saved from being fired due to his enthusiasm and his friendship with his boss. He moans that he'll never become a journalist, though fortunately before the only time his Rider powers actually DO help his job in episodes 18 and 19.
- Deflector Shields - The Seal Advent Card, which protects the wielder from the attacks of a Mirror Monster in the real world.
- Diving Save - Satoru Toujou meets his end in this way to save a father and son.
- Doppelgänger Spin - Knight's Trick Vent. Jumps between this and Doppelgänger Attack; sometimes the clones physically existed and would attack, but other times they were just distractions that would vanish when hit.
- Dramatic Gun Cock: Justified with Zolda's Magna Visor. He can fire it without cocking the gun, but he has to cock it to slot Advent Cards.
- Dynamic Entry: Femme's first appearance in the movie is her crashing through the ceiling and cutting up some Mirror Monsters before landing on her feet.
- Elemental Powers - Some of the Riders have one.
- The End of the World as We Know It - What happens if the Rider War runs on for too long.
- Everybody Lives - The true ending of the series.
- Eureka Moment: Megumi unknowingly gives Reiko one that leads her to realizing the connection between the disappearances and mirrors, and ultimately to the truth about the Rider War. Comically enough, while doing so, Megumi actually missed the opportunity to learn the truth much sooner.
- Everything Fades - Riders' corpses evaporate after a short while.
- Or, in a slightly more horrifying example, a Rider who reverts to human form in the Mirror World is stuck. For about five minutes until their body dissolves.
- Evil Twin - Kamen Rider Ryuga and his Contract Monster, Dragblacker.
- Extreme Omnivore - Asakura claims to have developed this trait to survive on the streets. Later on we see him take Kitaoka's seafood spaghetti and finish it, oyster shells and all.
- Eyepatch of Power - Reiko gains one out of nowhere in episode 5; a possible case of Written-In Infirmity, as she mentions in-show that she contracted pinkeye.
- Fanservice - Megumi. That is all.
- Five-Man Band
- A very rare case of the supporting characters (ORE Journal) instead of the actual 'heroes' (Kamen Riders) fitting this trope:
- Play straight in Hyper Battle Video, where four riders plus Agito team-up, Super Sentai style. This is only possible because it's Dream Sequence.
- Flash Step - One of Odin's abilities, which is part what made him nearly unbeatable, his opponents couldn't touch him. Also, Femme gains this with her Guard Vent.
- Generic Doomsday Villain: The Mirror Beasts not allied with any specific Kamen Rider. They mostly show up to battled in a Monster of the Week fashion, and like the Contract Beasts, they never speak and display so little personality that they appear to be around the level of hungry animals.
- Giant Enemy Crab - Scissors' contract monster, Volcancer.
- Gratuitous English: Okubo spouts this on occasion, but not as much as the Riders' Visors do.
- Heroic Sacrifice: Tezuka, Toujou, Shinji and Gorou.
- Heroic B.S.O.D. - Both Shinji and Ren go through these at various points in the story. Asakura has a Villainous B.S.O.D. of sorts at the end.
- I Call It "Vera" - Shimada names her iMac 'Amaryllis' and her laptop 'White Milky'.
- Megumi tries to rename the laptop "Gosaku". Shimada does not approve.
- I Coulda Been a Contender! - The original holder of the Raia Advent Deck was Yuichi Saito, a pianist who had suffered a career-ending injury; his wish would have been to repair the damage to his hands, but he refused the call.
- I Surrender, Suckers: Asakura does this frequently. Whenever he is caught by police, he always finds a way to get his deck back and/or get Venosnaker to help him out. Highlight to his escape from a heavily escorted police wagon.
- Identity Impersonator - Two fake decks were made for Kamen Rider Tiger so no-one would know who was behind the mask. In a later example, Gorou takes Kitaoka's place as Zolda when the latter finally succumbs to his cancer.
- Improbable Weapon User - Most notably Raia, Imperer and Verde.
- Irony - Despite the fact that Raia's Contract Monster, card visor and weapon all contain the word "Evil", he is actually one of the few genuinely good Riders.
- Incurable Cough of Death: Kitaoka has the bloody variant.
- In Spite of a Nail: Shinji when trying to change the past after Odin used his Time Vent, nothing he does manages to have an effect. The closest he came was warning Kitoako that Asakura would become a Rider and break out of jail. Kitoaka believed him, but decided against preventing Asakura from becoming a Rider because there had to 13 Riders in the battle the winner to get the prize.
- No matter the timeline, Shiro Kanzaki can never stop Yui's death or prevent Shinji from becoming a Rider.
- Ironic Echo: In the very first episode, Yui walks right up to Shinji and asks: "Are you a Kamen Rider?" (He wasn't one yet, but he had found the deck) Flashforward 48 episodes later, and after Yui has faded away, Reiko, who has seen Shinji transform and enter a mirror, and learned who the Riders are, as well as nearly everything important about the rider war, asking him the exact same question.
- It's All My Fault: Shinji, in the movie, realizes that because he couldn't keep his promise to meet Yui again when he was a child, the entire Rider War happened.
- Jigsaw Puzzle Plot: The main series itself is pretty easy to decipher (There Can Only Be One Kamen Rider, the Big Bad wants to win the war for himself with OP powers so he can save his sister) but the metaplot (This isn't the first Rider War, as the Big Bad keeps time travelling so he can find a way to save his sister, but Shinji becomes Ryuki and delays the killing) is a little harder to see. It's only implied in any way in the movies.
- Kick the Dog - Kitaoka faking his own death (well, Zolda's death) at the hands of Technical Pacifist Shinji (which sends him straight into a Heroic B.S.O.D.) was the moment that really established him as a total dick.
- Even Asakura feels the need to hammer this one home, about halfway into the series; he asks Reiko to help him meet with and reconcile with his brother Akira, his only surviving family after a fire claimed the lives of their parents - then announces that he was the one who started the fire in the first place, and proceeds to finish the job by feeding his brother to Venosnaker.
- Kagawa's personal policy, which he tries to teach Shinji - to be a hero, kick one dog if it means saving ten. Shinji believes otherwise.
- Non-human example: Darkwing put Eri into a coma before the start of the series, and after she regained consciousness, it went after her again.
- Laser-Guided Amnesia - Ren Akiyama undergoes a spot of this, which serves as helpful exposition into his backstory.
- Licensed Game: Obtained one, in which the game is played on a Playstation even though it was released in 2002... Though if it's good or not depends.
- Lovecraft Lite: So you've got a Mirror World which kills people that stay there too long, Monsters that can appear pretty much anywhere and pull them into it, and a shady antagonist who has nigh-godlike powers to control these monsters and even time.
- Loyal Phlebotinum: In one episode Kitoaka's injured and can't load his cards, and Shinji as expected agrees to be a pal and loads them into his own visor. Shinji expects to get to wield another Rider's weapons, but finds out for a Rider to activate a weapon they only have to be loaded into a visor, it doesn't matter whose, and Kitoaka gets his own weapons even though Shinji's using them in his gear.
- Meaningful Name: The Survive cards are handed out to riders so they can survive most of the fights. Shinji REALLY lives up to this, as he used the card for the first time, not to kill Mirror Monsters or Riders, but to survive so Ren won't go insane.
- Morality Pet - Goro acts as the foil to Shuichi's Jerk Ass behavior, never attempting to hide it once. Yui is this to Ren.
- Multiform Balance
- Joke Character: Blank Form, when a Rider does not posses a Contract Monster. The only Riders to have assumed this form are Ryuki and Ouja.
- Jack-of-All-Stats: All of the Rider's default form, as well as the only only one to most of them. Ryuki himself, for his adaptive deck, is this among the Riders.
- Super Mode: Ryuki and Knight's Survive Forms. In the SIC saga stories, Ouja and Raia get them too.
- Multiple Endings - The 13 Riders TV special that allowed viewers to phone in and choose one of two endings. The Bolivian Army Ending where Shinji decides to fight won.
- Mundane MacGuffin Person: Yui, who has been Dead All Along and is actually the centerpiece of the Rider War, as the person who runs it is her Knight Templar Big Brother is trying to rig in his favor so that he may save her life.
- Mundane Made Awesome:
- Watch as Shimada sets up her laptop in the cafe like an assassin assembling a sniper rifle. "Click...on...Send!"
- Also, Megumi and Gorou's "standoff" in Episode 30.
- Mythology Gag - Most Kamen Rider series feature a spider monster in the first episode; Ryuki raises the bar with a Giant Spider that comes back to life once.
- Also, the second encounter is often a bat. Guess which Rider Shinji meets first.
- Goro sometimes does Rider 1's and Agito's henshin poses as part of his Red Herring routine.
- The Double Rider Kick appears a few times - once at the end of the Hyper Battle Video (Ryuki and Agito), and once when Shinji and Ren have to fend off a Mirror Monster unmorphed.
- A minor design gag - Ryuki's eyes, Knight's mouthpiece, and Zolda's antennae all evoke the original Rider.
- Though the whole routine isn't the same, Shinji and Ren's henshin poses incorporate those of Rider 1 and Rider 2, respectively.
- Names to Run Away from Really Fast - Ouja's fusion monster is called Genocider.
- Subverted with Evildiver, who belongs to one of the good guys at first.
- When you deal with a final attack called End of World, you know that it's in your best interest to keep out of the area.
- No Body Left Behind - Those who die in the Mirror World disintegrate into nothing.
- No Good Deed Goes Unpunished: Shinji makes his debut fight after entering a contract with Drageder and saves Ren, and Ren replies by trying to kill him, nearly succeeding until Yui threatens Ren into stopping.
- Not Me This Time: Shinji and Ren hear about a ship where all the occupants disappeared and realized it was done by Mirror Beasts, and when they investigate they find Asakura and naturally assume it was his doing, and obviously don't believe him when he denies it, but he turns out to have been telling the truth and a trio of Mirror Beasts not connected to him were the real culprits.
- No Plans, No Prototype, No Backup - Used straight and averted; Kanzaki keeps the blueprints of the Advent Decks to himself but before he could do so, Kagawa read his work and used his Photographic Memory to reproduce it.
- Not Quite Dead - Kamen Rider Odin, three times.
- Note to Self: After Odin's Time Vent has caused him to relive the entire Rider War up to that point, including the deaths, Shinji uses this tropes. Hundred of Postit notes in both his room and his office (to the frustration of Yui and Ookubo) all with the same words: Punch where there's Golden Feathers. It lets him score the first hit on Odin at that point...... And has no effect.
- The punch may not have caused damage, but it proved to Shinji that he could fight against Odin and the time loops, even if the only real change he could make was landing a punch where he couldn't before. This is important as only Shinji, not being chosen by Kanzaki Shiro, can fight against the loops. He will always become a Rider, no matter what Kanzaki does.
- Oddball in the Series: How different Ryuki was when it was new is something that goes over the heads of many because many of its ideas remained in the franchise. Non-insectoid Riders? Only Agito ever changed that. Carrying around a Transformation Trinket in their pockets like it's Super Sentai? That was out of the blue. Highlander-like plot? That's the one part that wasn't touched again until Gaim. Grey and Black Morality was also new to the series. Even the Theme Song being less 'root for the hero' and more 'J-pop song that sorta touches on the series' themes' was new. Today this series is a lot less idiosyncratic because the aforementioned elements stuck, to the point of being quite passé. But when Ryuki was new, it was very much Kamen Rider In-Name-Only, with nothing but the main duo having the Rider 1 and 2 poses to suggest that it was supposed to be a KR series.
- In fact, the reason The Movie is an alternate ending without going into a full-on Elseworld (like the other KR movies of the decade) or an extra-long episode (like most Toku films) is because they didn't know they were going to get a full season at that point.
- "On the Next Episode of..." Catch Phrase: The quote atop the page (or in Japanese, tatakawanakereba, ikinokorenai!).
- Ontological Inertia - Shinji discovers this the hard way, and later Shiro Kanzaki comes to realise it too.
- Out of Character - Played for comedy in the Ryuki VS Agito special. Ryuki, Knight, Zolda and Ouja team up against an evil Agito. The latter 3 act like stereotypical heroes of justice, despite the fact they act very selfish in the real series. Lampshaded by Shinji when even Ouja, an axe crazy murderer, proclaims he is a fighter of justice. In the end, the whole sequence is revealed to have been a dream, much to Shinji's dismay.
- Pet the Dog - Even Asakura of all people gets a chance, when he saves a small girl from 3 bug-like Mirror Monsters. Admittedly it was just so he could destroy them himself, but still. It's worth noting that the initial rumors only mentioned 'three monsters', making Asakura a prime suspect of sorts (because he had contracted Jun's and Tezuka's monsters as well after killing them), but Shinji and Ren gave him the benefit of the doubt.
- An offscreen version takes place earlier in the series, when Kitaoka helps out another little girl by paying for her mother's surgery. There's some kind of pattern here...
- Sort of a pattern. See Diving Save above for an example with a little boy.
- Phantom Zone - Mirror World.
- Police Are Useless: AND HOW. Justified with the Mirror Beasts, they have almost no way of finding or fighting them, but even when Asakura is in a position where his Mirror Beasts can't help him, half the time they still fail to slow him down.
- Power Copying - Ryuki Survive's Strange Vent card always transforms into a copy of the next card his opponent will use.
- Power Levels: Each Advent Card has a listed Attack rating in multiples of 1000. These seem very unreliable since a clash between Knight and Scissors' Final Vents left Knight taking more damage.
- Real Men Wear Pink: Raia.
- Recap Episode: Episode 28, sort of. Time Vent's use effectively recaps the story to that point.
- Red Oni, Blue Oni: Shinji and Ren.
- Redemption Equals Death: Toujou.
- Reset Button: Time Vent.
- Reset Button Ending: Happens at least five times, probably more.
- Ripple Effect-Proof Memory: Because he was never chosen by Shirou Kanzaki, Shinji is the only one who can resist the memory-erasing effects of Odin's Time Vent.
- Running Gag: In the second episode, Shinji racks up a 50,000 yen debt to Ren after Yui smashes a store window to save his life, and Ren volunteers to pay for it. This debt is constantly increasing throughout the series: Ren's itemised bill includes charges such as "Keeping Me Awake Fee" and "General Annoyance Fee".
- Save the Villain: Shinji attempts this twice, once when Odin used his Time Vent, and having some memory of how things occurred with Suuichi, tries to prevent his death, but fails. Later does this for Asakura of all people, because a girl his saved, abit for less then heroic reasons, seeing him would encourage her to get better, he makes sure that he can feed his Contract Beasts on a trio of Mirror Beasts he was hunting.
- Say My Name: "Yui."
- Miho/Femme's "ASAKURA!!!" in Episode Final.
- A hilarious example by Shinji: "RON!!"
- Set Right What Once Went Wrong: Shirou Kanzaki attempts to do this multiple times to get the ending that he wants. While he is successful in altering inconsequential details, he never manages to save Yui or prevent Shinji from becoming a Rider.
- Shout-Out: Ren's first memory on recovering from his Laser-Guided Amnesia (see above) is an image on a woman in a white dress on a beach, just like Shoichi (they were actually Ren's girlfriend and Shoichi's sister respectively).
- Shiro Kanzaki went by the name Shiro Takami when he studied overseas - both names allude to Shiro Kazami, better known as Kamen Rider V3.
- The transporting of Asakura in ep 36, to Silence of the Lambs - only they didn't put a muzzle on him till ep 40. And just to hammer it home, he stages another jailbreak by swapping places with his victim, strapping the victim into his Hannibal chair while he himself gets carted out on a stretcher.
- And the effect of Freeze Vent on CGI monsters like Genocider looked an awful lot like Duke Org Loki's freezing-and-capturing of the Power Animals in Hyakujuu Sentai Gaoranger.
- One way to distinguish between the two Alternative Riders is the silver stripes on Alternative Zero, a reference to the primary difference between the first two Kamen Riders (Hayato Ichimonji's suit had the silver stripes).
- Shinji and Ren have Rider #1 and Rider #2's poses, respectively.
- Stepford Smiler - Mitsuru Sano (Kamen Rider Imperer).
- Summon Magic - The Advent Advent Card summons that Rider's Contract monster.
- Super-Persistent Predator: Mirror Beasts. Any time a human catches they attention, they will chase it relentlessly until either they kill and eat it, only pausing if they need to fight to defend themselves or, if it's a Contract Beast, threatened by a Sealing Card or their respective Rider entering a Contract. Over the series Shinji and Ren end up guarding people from Monsters that failed to eat them.
- Superpower Lottery - You've got Zolda with the Game Breaker Final Vent, you've got Ouja who gets three monsters, you've got Imperer who has a herd of monsters, you've got Odin who was designed to win the Rider War and then you've got Ryuki, who needs to use up one card to summon a serviceable hand weapon. Lampshaded when Raia chooses to use Copy Vent to 'borrow' one of Ryuki's weapons rather than use his own.
- Swiss Army Weapon - Ryuki Survive's Drag Visor-Zwei and Knight Survive's Dark Visor-Zwei.
- There Is No Kill Like Overkill - Zolda's Final Vent, aptly named "End of World"
- These Hands Have Killed - Ren does this after he kills Kamen Rider Odin in self-defense.
- Shinji, after he thinks he's killed Zolda.
- This Is a Drill - Knight's Final Vent.
- Time Travel - Scads of it. It was only used twice in the series, once in attempting to remove Shinji from the war and the second time to make sure it never happened in the first place, but the entire metaplot is that Shiro Kanzaki obssessively reset time again and again to find a way to save Yui. The TV series is his final attempt, with Yui finally convincing him to end it all.
- Transforming Mecha - Dragreder and Darkwing evolve into Dragranzer and Darkraider, which transform into Cool Bikes.
- Transformation Is a Free Action: Justified, since none of the real combat takes place in the normal world, and the Riders have to go into the Mirror World to fight. Since most of the Riders want their beasts to get stronger by absorbing the energy of enemy Monsters (Aside from Kitaoka) and the monsters only attack in the Mirror World, they have all the time they need to transform. Survive form also justifies this, as anyone who activates it is protected by auras of Wind or Fire (depending on the card used) while they transform.
- Trope Codifier: Ryuki influenced later Rider shows A LOT. Collectible devices, talking Transformation Trinket (Though that was actually for their weapons) and rival Riders? Ryuki was the one that started the trends that would be present in every show afterward.
- It also popularised many of the tropes established with Battle-Royale style anime in Japan, being the first to present combatants fighting alongside supernatural entities, and the idea of the battles being fought for the sake of a wish being granted.
- Upgrade Artifact - Played straight and subverted. When Shinji becomes Ryuki he suddenly gains the knowledge of how to hold a sword properly, how all his new abilities work and how to perform one hell of a flying side kick. However, as far as his general combat technique goes he's useless when he first becomes a Rider and only marginally improves when he upgrades to Ryuki. He slowly gets better as the series progresses; by the end his fighting skills are up there with the best of them.
- Played even straighter with the other Riders. Kitaoka is a terminally ill, golf-playing lawyer. Shibaura is a computer nerd. Kagawa is a mild-mannered middle-aged academic. Only Ren (bar room brawler), Sudou (hardened cop) and Asakura (psycho outlaw) have plausible fighting skills.
- Then again, those Riders are never shown to have good hand-to-hand skills. Kitaoka sticks to ranged combat and is woeful at hand-to-hand. Shibaura and Kagawa's deficiencies are made up by the sheer power of their armour.
- Surive Cards play this even straighter: Shinji and Ren become much more powerful, and barring Shinji justifiably being mystified by the aptly named Strange Vent, they immediately knew how to use all of their new weapons and powers.
- Villainous Rescue: Ryuga makes his appearance in Episode Final by entering the fight between Femme and Ouja, then saving Miho from getting killed by Asakura and proceeds to curbstomp Asakura.
- Well-Intentioned Extremist - While this may apply to some of the Riders, Shiro Kanzaki is the biggest example in the series. All he wants to do is save Yui's life, and it could even be argued that by recruiting people such as Shibaura, Asakura and Takamizawa, he'd be doing the world a favor by ridding the world of such deranged criminals through having them kill each other off.
- What If? - Miyuki/Kamen Rider Raia was the original owner of the Survive Shippu card, but willingly gave it to Ren. Since then, Toei has released art and figures of what Raia Survive◊ and Exodiver, the Survive version of Evildiver◊, would have looked like.
- Woobie, Destroyer of Worlds: Shiro Kanzaki. He and his sister are raised by abusive parents, and he's forced to watch Yui die while being unable to save her. Even once the Rider War begins, he has to watch her die over and over again due to repeatedly failing to save her.
- The Worf Effect - Played straight with most of the Riders' debuts, such as when Zolda breaks out his Final Vent for the first time against both Ryuki and Knight. Subverted when the maggot monsters' first battle after evolving into a more powerful form is with Ouja - and he tears through a whole mob of them to start with.
- X Meets Y - Simple, it's Kamen Rider meets Highlander meets Neon Genesis Evangelion.
- Zerg Rush - Imperer's Final Vent. Also the swarms of maggot monsters towards the series finale.
