History Series / KamenRiderRyuki

* {{Cameo}}: Several members of ''Series/KamenRiderAgito'''s cast, including three of the Riders, appear in ''Episode Final''.

* ''Series/KamenRiderGeats X Series/KamenRiderRevice: Movie Battle Royale'' (2022), a crossover film that also features cameos from Ryuki, Knight, Ouja, and Ryuga; to celebrate ''Ryuki''[='s=] 20th anniversary and because ''Geats'' and ''Ryuki'' share DeadlyGame themes.

** Ouja also makes a guest appearance in ''Geats''[='=] own ''Televi-kun'' DVD episode, ''Kamen Rider Geats: What the hell?! Desire Grand Prix Full of Men! I'm Ouja!'' (2023); and features a battle at the climax where some of Geats' Riders borrow the powers of Ryuki and Ouja.

Voted #6 series in the Heisei era and #6 product overall in NHK’s All Kamen Rider Popularity Vote.

In addition to the main series, ''Kamen Rider Ryuki'' had three spinoffs during its run. ''Kamen Rider Ryuki: Ryuki vs. Series/KamenRiderAgito'' is a DVD episode that was distributed by ''Televi-kun'' magazine where ''Ryuki'' crosses over with the preceding season (though it's AllJustADream of Shinji's). ''Film/KamenRiderRyukiEpisodeFinal'' and ''Kamen Rider Ryuki Special: 13 Riders'' are a movie and TV special, respectively, set in {{Alternate Timeline}}s to the main series. In 2018, Ryuki received a web-exclusive 3 episode miniseries called ''Rider Time: Ryuki'', spinning out of Shinji's return cameo in ''Series/KamenRiderZiO''. Kamen Rider Ouja would also return in the ''Series/KamenRiderExAid'' spinoff ''Kamen Rider Brave: ~Let's Survive! Revival of the Beast Rider Squad!~'' (2017), and again in the villain-focused spinoff ''Series/KamenRiderOutsiders'' (2023), which builds on the plotline of ''Let's Survive!''.

** There's also a deconstruction of the LetsYouAndHimFight and ConflictBall 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 UnbuiltTrope though, since the two tropes didn't have a massive occurrence [[Series/KamenRiderFaiz until]] [[Series/KamenRiderBlade right]] [[Series/KamenRiderKabuto after this show.]]

-->''"Those who do not fight will not survive!"''

* LastChanceToQuit: After meeting Shinji, Ren offered him a deal to spare him from the War. Since he had yet to bond with Mirror Monster, he wasn't officially a part of the competition. Therefore, if Shinji would give Ren the Advent Deck he accidentally found and walk away now, he go back to his normal life with no strings attached. Unfortunately for Shinji, his innate morality was too strong to let him ignore than dangers the Mirror Monsters posed to normal people, so he made a contract with Dragreder to become a full Rider, locking himself in to the Rider War permanently.

* FiveManBand
** A very rare case of the supporting characters (ORE Journal) instead of the actual 'heroes' (Kamen Riders) fitting this trope:
*** TheHero: Ookubo certainly thinks of himself as this, but exhibits TheBigGuy behavior at times.
*** TheLancer: Reiko
*** TheSmartGuy: Shimada
*** TheChick: Shinji, [[TheHero the real Hero]].
*** SixthRanger: Megumi
** Play straight in Hyper Battle Video, where four riders plus [[Series/KamenRiderAgito Agito]] team-up, Franchise/SuperSentai style. This is only possible because it's DreamSequence.
*** TheHero: Ryuki
*** TheLancer: Knight
*** TheSmartGuy: Zolda
*** TheBigGuy: Ohja
*** EleventhHourRanger: Agito

* BittersweetEnding: [[spoiler:The real ending has Shiro Kanzaki pressing the ResetButton again, only this time, he and Yui die in that reality, however, that means no Mirror World and no Rider Wars which means every participant has no memories of it and making it a safe peaceful reality.]]

In addition to the main series, ''Kamen Rider Ryuki'' has three spinoffs. ''Kamen Rider Ryuki: Ryuki vs. Series/KamenRiderAgito'' is a DVD episode that was distributed by ''Televi-kun'' magazine where ''Ryuki'' crosses over with the preceding season (though it's AllJustADream of Shinji's). ''Film/KamenRiderRyukiEpisodeFinal'' and ''Kamen Rider Ryuki Special: 13 Riders'' are a movie and TV special, respectively, set in {{Alternate Timeline}}s to the main series. In 2018, Ryuki received a web-exclusive 3 episode miniseries called ''Rider Time: Ryuki'', spinning out of Shinji's return cameo in ''Series/KamenRiderZiO''.

* BittersweetEnding: [[spoiler:The real ending has Shiro Kanzaki pressing the ResetButton again, only this time, he and Yui die in that reality]]

* BondCreatures: The Mirror Monsters that are neither monsters of the week nor under Kanzaki's direct control.

** 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.

* TimeTravel: ''Scads'' of it. It was only used twice in the series, [[spoiler: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 [[spoiler: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.]]

** More than that, compare Kamen Rider Knight with... [[NamesTheSame Knight]], [[http://www.comicbookresources.com/prev_img.php?pid=6213&cover=1 Batman's British counterpart]]. (It's got to be unintentional; as Knight has been stuck in ComicBookLimbo for fifty years and only got out recently.)

** SeldomSeenSpecies: Evildiver/Raia (a ray), Blancwing/Femme (a swan), Gigazelle/Imperer (gazelles), Psycorogue/Alternative Zero (a cricket).

** Zolda and Tiger's Final Vents. For the former, it's GameBreaker 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. [[spoiler:The one character who takes it head on is badly injured, but survives... [[KilledOffForReal 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).

* BlindIdiotTranslation: See HilariousInHindsight over on the [[YMMV/KamenRiderRyuki YMMV page]]. A full list about halfway down [[http://www.animeniacs.com/index.php?act=reviews&subact=d_qrev&id=317 this page]].

* NoteToSelf: After [[spoiler: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 ([[SugarWiki/FunnyMoments 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...... [[SubvertedTrope And has no effect.]]

* ResetButton: [[spoiler:Time Vent.]]

* SpiritualSuccessor: To ''Series/KamenRiderBlack'', both series features a conflict between Kamen Riders as the main point of the story. While ''BLACK'' has the titular Rider and his step-brother turned Rival are the only competitors who were fated to clash to the death for the right to rule the world, ''Ryuki'' features a total of 13 Riders (and 2 additional Pseudo Riders) competing to the battle to the death with the winner granting a single wish.

* SuperpowerLottery: You've got Zolda with the GameBreaker 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 [[spoiler: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.

%%* SpiritualSuccessor: To ''Series/KamenRiderBlack''.

* ShoutOut: The transporting of Asakura in #36, to ''Film/TheSilenceOfTheLambs'' -- only they didn't put a muzzle on him until #40. And just to hammer it home, [[spoiler: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.]]

!!Henshin! ''Trope Vent!''

!Recurring ''Kamen Rider'' tropes include:

!This series contains examples of:

** ALoadOfBull: Magnugiga/Zolda (it's a minotaur)

** There's also a few [=SIC=] Hero Saga stories that serve as this. The first, ''World of If'', which has Shinji become ''Ryuga'' and Yui takes Kagawa's place as Alternative, as well as having Ryuga and Ouja get survive forms; the second, ''Advent Calendar'', has Ouja gathering ''all'' the contract monsters and combining them into Genosurvivor, only to have him and Genosurvivor get killed by Zolda's Final Vent (which also takes Zolda and his contract monster out), with Shinji's deceased brother possessing Shinji, becoming Ryuga, who wins the war and wishes all the riders back to life.

* BlessedWithSuck: 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.

* ChronicBackstabbingDisorder: Toujou and Sano.
* ClothesMakeTheSuperman: 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 [[LegacyCharacter original Ryuki]] in the ''13 Riders'' TV special.

* CosmicHorrorStory: Averted. It looks very much like one at a glance, but the Rider War happened because a human, Kanzaki, made it happen. [[spoiler: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.]]

** [[WildMassGuessing Then]], [[{{Defictionalization}} the fighting game for Playstation is...]]

* GenericDoomsdayVillain: The Mirror Beasts not allied with any specific Kamen Rider. They mostly show up to battled in a MonsterOfTheWeek 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.
* GiantEnemyCrab: Scissors' contract monster, Volcancer.

* NotMeThisTime: 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.

* OutOfCharacter: Played for comedy in the ''Ryuki vs Kamen Rider Agito'' Hyper Battle Video 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.

* PoliceAreUseless: 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.

* SaveTheVillain: Shinji attempts this twice, once when [[spoiler: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.

* SuperPersistentPredator: 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.

* UpgradeArtifact: 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.

* ZergRush: Imperer's Final Vent. Also the [[BugWar swarms of maggot monsters]] towards the series finale.
