[[http://www.fanfiction.net/u/676659/Kamen-Rider-Chrome Kamen Rider Chrome]], the one behind ''[[Fanfic/LoveHinaDoubleTrouble Love Hina Double Trouble]]'', ''[[Fanfic/KamenRiderOOOTheMetalsOfIkkiTousen Kamen Rider OOO: The Medals of Ikki Tousen]]'', ''[[Fanfic/KamenRiderDays Kamen Rider Days]]'', the ZKDTrilogy and ''[[FanFic/RosarioToKiva Rosario to Kiva]]'', has done it once again. This time he has taken two very different tales an mixed them up together. And the result is this ''RosarioToVampire'' MegaCrossover and unofficial ''Manga/KamenRiderSpirits'' spin-off known as ''[[http://www.fanfiction.net/s/7182250/1/Showa_Vampire Showa & Vampire]]''.

[[TheFuture The year is 23XX A.D.]] On her first day to Yokai Academy, FriendlyNeighborhoodVampire Moka Akashiya finds a mysterious boy named Shinichi Sanban (later Banabara), who is unable to remember anything about himself. As the day goes by, he learns from Kamen Rider Ichigo himself that he is a super cyborg known as a Franchise/KamenRider. Shincihi and Moka soon go on adventures that span from the monster world to the human world and beyond to discover the secrets of his past, making new friends and enemies as they go.

The character, Shinichi Banabara, is basically the Showa Era counterpart to ''Series/KamenRiderDecade'', and fittingly, he's called Kamen Rider Showa. On another note, this is really a [[ContinuityReboot reboot]] fanfic to another MegaCrossover ''KamenRiderShowa''. You can find it [[http://www.fanfiction.net/s/4816951/1/HIGURASHI_NO_NAKU_KORO_NI_KAMEN_RIDER_SHOWA here]], but beware of major spoilers unless you've already read it.

This being a MegaCrossover, the story features several plots and characters from other franchises, both supernatural and science fiction. The list goes as follows; ''{{Halo}}, RedVsBlue, Anime/YuGiOh5Ds, GhostInTheShellStandAloneComplex, Manga/{{Bleach}}, ZoidsNewCentury, FrankenFran, PrincessResurrection, {{Karin}}, VideoGame/MegaManX, TenchiMuyo, Manga/KatekyoHitmanReborn, SoulEater, Anime/YuGiOhZexal, {{Mai-Otome}}, {{Pokemon}}, Manga/FairyTail, VideoGame/{{Darkstalkers}}, HighSchoolDXD, VideoGame/MegaManStarForce, [[Anime/MobileFighterGGundam G Gundam]], {{Hellsing}}, {{Trigun}}, VideoGame/{{Xenosaga}}''... and there's still more to come.

''Showa & Vampire'' was published from July 15, 2011 to December 14, 2012, spanning 69 chapters (68 + epilogue) over seven story arcs. A sequel, called ''[[http://www.fanfiction.net/s/8856310/1/Showa-Vampire-II-Chronicles-of-the-Kamen-Riders Showa & Vampire II: Chronicles of the Kamen Riders]]'', is currently ongoing with the first two chapters (prologue + chapter 1) published on December 31, 2012.

Even though Chrome is the main author of this fanfic, there are other authors that contributed as well, including Tailsmo4ever, Kamen Rider Bushido, Kamen Rider Goji, Shadow Element 13, and [=GuyverGenesis=].[[note]]According to Chrome in his post-Season 1 comment and some post-chapter comments.[[/note]]

This fic also has two {{spinoff}}s, one called ''[[http://www.fanfiction.net/s/7639449/1/Showa_Vampire_GAIDEN_Tails_of_the_Liger Showa & Vampire GAIDEN: Tails of the Liger]]'', which centers on Yuji,[[note]]''Tails of the Liger'' takes place after the New Term Arc but before the Sports Fest arc.[[/note]] and another called ''[[http://www.fanfiction.net/s/8408979/1/Showa-Vampire-GAIDEN-Breaker-s-Lyrics Showa & Vampire GAIDEN: Breaker's Lyrics]]'', which centers on Goemon.[[note]]''Breaker's Lyrics'' is set after chapter 28. It is currently on an indefinite hiatus[[/note]] There is also a one-shot {{Prequel}} called ''[[http://www.fanfiction.net/s/7555153/1/Project-NUMBERS Project NUMBERS]]''.

On April 2, 2014, Chrome announced the series had been cancelled and was going through a reboot. The sequel has been taken down and chapters from the sequel have been moved to Volume 1.

Now has a [[Characters/ShowaAndVampire character sheet]] in need of some attention.

[[foldercontrol]]
----
!This fanfiction series contains examples of:

[[folder: ABC]]
* AbsurdlyYouthfulMother: Yuji's mom has the excuse of being an immortal dragon demigod like him, but we're told about how both Shinichi and Ren's moms are both really young and hot-looking.
* AcePilot: Played straight and subverted. Michiru is one of the best pilots GIN-SHOCKER has produced. However, according to the NUMBERS, she always crashes when attempting a landing. Misato even claimed that she crashed a ''simulator''.
* AdaptationNameChange: Daichi's Rider form in ''Showa'' was Kamen Rider Musician. Here, he is renamed Sonix. Also doubles as a MeaningfulRename and a MythologyGag.
* [[spoiler:AdaptiveArmor: As of Tail 8 of ''Tails of the Liger'', the Liger System turns out to be one, as it activated Torrent Form as soon as it recognized Yuji was in the ocean.]]
* [[spoiler:AbusiveDad: The FreudianExcuse of Goemon.]]
** [[spoiler:Michiru's handler, Dr. Montesinos, is implied to have sexually abused her.]]
* TheAlliance: As of season 2, the former NUMBERS, ex-GIN-SHOCKER members (Dr. Magi and Dr. Washam), [[spoiler:Jagers]], and Youkai all team up to fight against GIN-SHOCKER.
* AllWomenAreLustful
* AllYourPowersCombined: The [[color:gold:Legacy]] Mode, which combines the powers of all 13 Riders. [[spoiler:Fourteen now that Kamen Rider Shin is included]].
* AlternateUniverse: ''Showa'' took place in the ''Higurashi'' universe. ''Showa & Vampire'', being a [[ContinuityReboot reboot]] of the former, takes place in the ''[=RosaVam=]'' universe.
* AmericanAccents: General Nagazawa has a Texas Drawl, while Ren speaks with an urban accent.
* AmnesiacDissonance: [[spoiler:Shinichi, after learning everything about his past.]]
* AnimalMotifs: So far, the Kamen Riders seen here are based on some animals:
** '''Kamen Rider Showa''' and Kamen Rider Phantom: A cicada. Possable shout out to ''{{Higurashi}}''.
** '''Kamen Rider Liger''': [[ExactlyWhatItSaysOnTheTin Take a guess]].
** '''Kamen Rider Necros''': An Anubis. Or more accurately, a jackal.
** '''Kamen Rider Mega''': A firefly.[[note]]His motifs become a lion, a pegasus and a Chinese dragon when he enters Inferno Leo, Diamond Pegasus, and Storm Dragon forms receptively.[[/note]]
** '''Kamen Rider Carmen''': An orchid mantis.
** '''Kamen Rider Arachnea''': A tarantula.
** '''Kamen Rider Seras''': A mosquito.
** '''Kamen Rider Parasyte''': A tick
** '''Kamen Rider Scanner''': A leech.
** '''Kamen Rider Breaker''': A centipede
** '''Kamen Rider Bomber''': A gold-ringed dragonfly.
** '''Kamen Rider King''': A dobsonfly.
** '''Kamen Rider Slasher''': A soilder termite.
** '''Kamen Rider Zero''': A wasp.
** '''Kamen Rider Armadillo''': A pillbug.
** '''Kamen Rider Sonix''': A cricket.
** '''Kamen Rider Petrifier''': A jewel beetle.
** '''Kamen Rider Whirligig''': A whirligig beetle.
** '''Kamen Rider Whiplash''': A scorpion.
** '''Kamen Rider Inferna''': A fire ant.
** '''Kamen Rider Atlas''': An atlas moth.
** '''Kamen Rider Storm''': A stag beetle.
** '''Kamen Rider Dynamo''': A rhinoceros beetle.
* AnimeHair: Yuji is the primary source of this.
* [[spoiler:AntiAntiChrist: Shinichi Banabara]]
* AntiVillain: Lina fits the bill, as the only reason she worked for GIN-SHOCKER was because she was still in love with Shinichi. [[spoiler: Thankfully she's convinced to switch sides.]] Dr. Magi and Dr. Washam to a lesser extent.
** [[spoiler:And then there's Celeste, a.k.a. Acid Snake. Sure she was ordered by Gebok to attack (and later spy on) Leon and wanted no part in his scheme, but she got along well with Leon and Tamao and even saved Tamao's life near the end.]]
** [[spoiler:[[Anime/MobileFighterGGundam Dr. Rain Mikamura]], as well. She was forced to work for GIN-SHOCKER and wanted nothing to do with their schemes. And when TheAlliance came to rescue Shinichi, she saw this as an opportunity to escape their clutches.]]
* ArbitraryScepticism: During the Sports Fest, Shinichi asks if they might run into a real minotaur. While going out with a vampire, a witch, a yuki onna, and a succubus, being a cyborg, etc.
* ArcNumber: 13
* ArchEnemy: Gebok for Shinichi, General Nagazawa for Yuji, Warden Anju for Netto, and Admiral Ankokou for Leon.
* [[UpToEleven Astonishingly]] OpenMindedParent: Shiori in a nutshell. While Shiori does worry for Shinichi's mental state and physical well-being in light of his experiences as a Kamen Rider, she is not only perfectly all right with Shinichi having a sex life, she ''encourages'' it! Fodder for her erotica novels, mind you, but still... Well, she's either this or an astonishingly rare example of the [[PervertDad Pervert Mom]]... although she is just as [[ChivalrousPervert chivalrous about her perversion]] as Shinichi is about his. [[LikeFatherLikeSon Like mother, like son]], after all.
** This also applies to Yuji's parents, Yusei and Aki. Yusei learned of GIN-SHOCKER through Carl Washam and was brought up to speed when his son returned home. Also, Aki was able to figure out that three cyborg assassins and a DarkMagicalGirl were her son's girlfriends, just by meeting them! She even accepted that Yuji had developed a harem with said girls, and is actually proud of him.
** Then there's Xianglian Xang, Qiao's birth mother and Netto's surrogate mother. As an [[TheEmpath empath]], she was able to quickly tell that Netto was getting a harem of his own. And she supports it!
* AttackAnimal: Essentially, this is what the NUMBERS were supposed to be. Taken literally with #13 (Shinichi) who had his memories, emotions and free will stripped from him by Dr. Gebok to make him the perfect weapon. Considering the powers and weapons the NUMBERS have been equipped with, which make them very lethal in their own individual ways, it makes a lot of sense they'd be classed as cyborg weapons at the same time they are considered soldiers of GIN-SHOCKER.
* BackFromTheDead: The NUMBERS.
** [[spoiler:Lina Shishigami.]]
* [[spoiler:TheBadGuyWins: Implied with GIN-SHOCKER already taken over the world according to Gebok in chapter 65 and justified in the season 1 finale when Shinichi and Yuji turn themselves over.]]
* BadPowersGoodPeople: Shinichi and Leon. The former [[spoiler:was made to be the [[UpToEleven Ultimate]] PersonOfMassDestruction]], and the latter has abilities that revolve around death, not to mention that he also has the powers of every Dark Kamen Rider to exist. In spite of this, both are very nice boys and many girls keep falling for them.
* BadassAdorable: Oh, ye who trifle with Hana or Yuji shall incur the wrath of Michiru, as she cares a great deal for them both.
* BadassBiker: All Kamen Riders have to have motorbikes and Shinichi is no different. He just gets his bike (Cyclone-X3) a little later from his debut appearance. Yuji is also one with his transforming D-Wheel "White Blaze".
* BadassNormal: Out of the NUMBERS revealed so far, Kamen Rider King is the only one who isn't heavily modified and his swords don't possess any powers, yet [[spoiler:before the Cicadroid knocked him off]] was able to fight and defeat Kamen Rider Showa.
** And Shinichi himself was showed to capable of fending off Sonix, Zero, and Armadillo without his armor. He does this again with the rival monsters he scorned when he returns to Youkai Academy.
* BadassPrincess: Elle Jacqueline de la Fortescue, Princess of the Sky Dragon Clan. And we can't forget Hime and Rias, of course.
* BareYourMidriff: Riza Wildman
* BarrierWarrior: Sora Matsuoka possesses a mutant ability to create hexagonal-shaped barriers of energy. [[spoiler:She used it to protect Necros from an attack from Scorpio-Borg. Also, one of Kage no Shi's abilities is to create a impenetrable shadow barrier.]]
* BattleThemeMusic: Whenever Shinichi unlocks a new Rider in the middle of a fight, that Rider's theme song plays. Theme music is also applied during every major battle. Listening to the songs whenever the specific scene is read enhances the experience.
* BeachEpisode: ''Tails of the Liger'' - "The Surging Torrent"
* BedmateReveal: Daichi gets one with Haruhi in chapter 62, complete with a variation of WhatDidIDoLastNight.
-->"WHAT THE HELL HAPPENED LAST NIGHT!?"
* BerserkButton: All four main Riders share the same button, and it's labeled "HARM THOSE WHO THEY CARE ABOUT".
** And (as of chapter 62) DON'T mention Siria's engagement. Kiko almost learned this the hard way had it not been for Qiao at the last moment.
** Shogo's [[UnfortunateName name]] is also a touchy subject.
* TheBerserker: BLACK 13, [[spoiler:or at least the Anti-Rider program chip used to make him act that way before Kurumu fried it]]. Shinichi becomes like a relentless beast whose only purpose is to destroy other Riders. Shinichi also ends up like this when pushed too far by an imminent threat to either himself or those he cares about.
* BettyAndVeronica: Michiru and Hana, respectively.
** Another example, Reiri and Hime.
* BewareTheNiceOnes: Just about anyone in the story you can think of, but this one has to go to Reiri. A well mannered and flirtatious Vampire who likes to tease and drink the blood of cute boys, she's the last person you'd expect to blow her top. In the cannon anime where she's from, she's only seen getting mildly annoyed, and not outright angry. But the moment she meets her surrogate brother's kidnapper face to face...
-->''"[[Film/TheRunningMan I hope you have enough room for my fist, because I'm going to ram it into your stomach and break your goddamned spine!]]''"
* {{BFS}}: Shiroha wields one out of a stone slab in season 2. Leon also wields one. See WeaponTropes below.
* BiTheWay: Yuki, though she prefers women more.
** Aki and Shiori are implied to be this way too, if their flirting towards one another says anything.
** Hana and Michiru make out in the beach orgy in Tails of the Liger, and during the Halloween festival arc Qiao's said to be helping Elle with being in "dragon heat" at one point.
* BigBad: GIN-SHOCKER.
** BiggerBad: [[spoiler: JUDO, the Great Leader of GIN-SHOCKER.]]
* [[spoiler:BigBadDuumvirate: Gebok and Ishigami/Madame Medusa towards the end of the first season.]]
* BigBrotherMentor: Yuji is this to Shinichi and Netto.
* BigDamnHeroes: The Yokai Academy girls, the other Riders, and even Bast-Sora and Aphrodite arrive in the nick of time to save Yukari and provide Shinichi with very valuable backup, ending with a vicious curb-stomping of the GIN-SHOCKER NUMBERS.
* TheBigDamnKiss: Chapter 7.
-->[[spoiler:'''Inner Moka:''' "How's ''that'' for a down payment?"]]
* BirdsOfAFeather: Goemon and Ren seem to be this, as they quickly bonded over a common interest --- break-dancing.
* {{Bishounen}}: Netto is described to be this. Most likely takes after his mother.
* BlackComedy: Plenty. A prominent example is this little gem Michiru delivered.
-->'''Michiru:''' "OK, everyone. We'll be departing for Baghdad pretty soon. Make sure your harnesses are on tight. Oh, and this might be a good time to use the bathroom because there is none on this flight. We don't even have inflight movies or snacks. Oh, and if you feel nauseous then too bad because we don't include barf bags either. And in case of a water landing, your fellow passenger may be used as a floatation device. In case of a crash landing, pray to whatever deity or divine being you worship and brace for impact."
* BlackEyesOfEvil: Not exactly evil per se, but Shinichi's eyes do occasionally turn black when he's starting to get seriously angry.
** [[spoiler:Yuji's eyes get like this whenever his alter ego, Abyss, takes over.]]
** [[spoiler:Qiao's sclera and iris turn black and her pupils narrowed and silver when her dark side manifests.]]
* BlackSheep: Yuri Fudo, Yuji's older brother, is rarely seen or heard aside from stories from Yuji's past.
* BlondesAreEvil: Dr. Gebok
* BloodKnight: Riza loves to fight. It's in her nature. Lampshaded by Ruby in ''Tails of the Liger''.
-->'''Riza:''' "I love mismatched fights. Makes it that much sweeter when I win!"
-->'''Ruby:''' "You're a battle-crazy maniac."
-->'''Riza:''' [[InsultBackfire "I'll take that as a compliment!"]]
* BondageIsBad: Kurumu has Ruby put in handcuffs and puts a ball gag on her. She also has a supply of vibrators to be used for "interrogating" the prisoner. Yuji was not amused.
* BondOneLiner: Showa's "Game Over!"
** Also, Mega's "You are deleted!"
* BreakingTheFourthWall: There has been some cases of this. For example, Nekonome in chapter 59:
-->"Minna-san~! I know I've been absent for several chapters but your teacher is back again to see how you're doing!"
** Gebok does this in chapter 65 during his interrogation with Leon after [[CurseCutShort cutting his curse short]].
--> "Uh-uh, temper, temper, kid. Children could be reading this as we speak you know. Even if this is rated M, [[WhatDoYouMeanItsForKids hardly anyone cares about that these days]]."
** Goemon does this later in chapter 67 during his fight with Kamen Rider Storm.
--> "OK, seriously! [[PutOnABus I've been gone for like, about 35 chapters]] and in this [[TheBusCameBack first team fight after my long absence]] I'm getting shocked for my troubles! That is seriously fucking bullshit!"
* BrickJoke: In the fifth chapter of ''Tails of the Liger'', Misato asks Hana if it's silly of her to be jealous of a cat (referring to [[SoulEater Blair]]). Hana simply tells her that it's only a cat and that it's not going to change into a woman, with Misato claiming that it will. Two scenes later, we see Blair in her human form sleeping with Yuji. Cue Misato screaming.
* TheBusCameBack: Goemon in chapter 67. Also [[spoiler:Sting Chameleon in season 2, chapter 1.]]
* TheCameo: [[Series/KamenRiderFourze Tomoko Nozama]] in chapter 3 of ''Tails of the Liger''.
* CatGirl: [[http://en.wikipedia.org/wiki/Bastet Bast]], the Egyptian Goddess of Joy, obviously. Don't forget Ms. Nekonome and [[SoulEater Blair]]. [[spoiler:And [[HighSchoolDxD Koneko]], too.]]
* CallingTheOldManOut: Pretty much the point of chapter 6 in season 2.
* CallingYourAttacks: Obviously. This was a standard in the Showa Era when the Rider calls out any of their special techniques.
* CannotTellAJoke: Invoked with Leon after listening to Yuji's plan in season 2.
-->'''Leon:''' "Alright, now we have to save them...so I can kick Yuji's ass for underestimating me."
-->'''Daichi:''' "If I were you, I'd take it as a compliment. Blowing shit up is all he ever sees you do."
-->'''Leon:''' "I was joking."
-->'''Hana:''' "[[LampshadeHanging You suck at comedy.]]"
* CantHoldHisLiquor: Yuji, full stop. Fortunately for him, he becomes a DrunkenMaster.
* TheCasanova: Shinichi is a mild example. Whenever he complements a lady, he does so with honesty.
* CentralTheme: ''Showa & Vampire'' has many of them, but these four are the main ones:
** Your past isn't the key influence on your life; it's the now the counts.
** Love comes in many kind of forms: romantic love, familial love, a brotherhood-based love, and one based around sacrifice (usually of life) for the other person.
** Once you start the CycleOfRevenge, you must continue that course until your enemies are defeated - or you are.
** Humanity is defined as being able to emphasize with one another - the prime example being the vampire Moka being much more human(e) than the cyborg Dr. Gebok.
** In other words, this fanfiction has a lot of themes correlating with [[UsefulNotes Existentialism]] (intentional or not is unknown) - it's what you make of yourself that counts, and only you can choose your own path, whether that be the path of justice (Leon), family (Yuji or Shinichi), or revenge (Shinichi (for a time) and the NUMBERS).
* TheChessmaster: Aside from Rias? [[spoiler:Gebok proves to be one as he deliberately allowed himself to be captured in order to send a signal from within the dungeons to weaken the Lilith Mirror's barrier, allowing the staff and students to run rampant when no one realized it. He even says himself that in Chess, sacrifices are needed for victory]].
** [[spoiler:Youkai Academy's headmaster, Tenmei Mikogami, is also this as he is the one who brought Shinichi to his school in the first place. Everything Shinichi has become up to this point was partly his doing.]]
* ChekhovsGun: [[spoiler:While Kurumu's Charm is strong enough to enslave all boys in school at once, it's also apparently strong enough to fry mind control chips embedded in cybernetic brains.]]
* ChekhovsGunman: Shogo reveals in chapter 31 that there was a penthouse on top of the girls' dorms, hinting someone of high class might be living there. Kurumu has also seen it before while flying, while Yukari claims it's "Possibly someone rich who thinks she's too good enough to rough it like the rest of us". One chapter later, Kiko was introduced, and it turns out the penthouse is actually hers.
** Remember Topper, the man in the top hat and bright clothes and owner of a local pawn shop? [[spoiler:Turns out in the season 2 prologue that ''he'' was the one responsible for [[MindWipe wiping Shinichi's memory of GIN-SHOCKER]] and making him who he was by the time the story kicks off.]]
* ChickMagnet: All four main Riders are, ending up with multiple girlfriends each.
* ChildrenForcedToKill: One of GIN-SHOCKER's major policies is absolutely ''no'' witnesses. The NUMBERS are often the ones being forced to take care of those loose ends, despite some of them not being happy to do it.
* ChildhoodFriends: [[PrincessResurrection Hime and Reiri]]. These two girls were Shinichi's kindergarten friends before he was kidnapped by Gebok so they haven't seen him for ten years. Hime even states that the last time they saw him was on the day before his sixth birthday, February [[ArcNumber 13th]], when Shiori was planing a party. Upon hearing he has returned they go to see him and discover he's a cyborg and a Kamen Rider as a result.
** And ''much'' later, [[HighSchoolDxD Rias and Akeno]] arrive during the Halloween Festival to reunite with Shinichi as well.
* ChildhoodFriendRomance: Netto and Qiao.
** Shinichi's harem believe that Hime and Reiri might become this for Shinichi. Subverted as they don't have romantic feelings for him, but still care a great deal for him.
* ChildSoldiers: The NUMBERS. Also the Jager Unit and Weapon D.
* ChineseGirl: Netto's girlfriend, Qiao Xang.
* ChivalrousPervert: Shinichi respects the females he's with even if he does appreciate the view.
* ClothesMakeTheSuperman: Showa changes forms into the other Riders, gaining their appearance and also their abilities. Applies to his friends when he uses the "Form Ride" on them as well. Necros can do the same thing as well.
* CombinationAttack: An old-time favorite.
** Liger Zero Phoenix w/Ruby: "''Crimson Mystic Inferno''"[[note]]Ruby and Liger Zero Phoenix create a red circle of magic runes and launch a dragon-shaped fireball at the target.[[/note]]
** Liger Zero]] w/Inferno Leo Mega: "''Wrath of the Beast King''"[[note]]Liger Zero and Inferno Leo Mega launch a wave of fire together that forms into a rushing lion and pounces on the target.[[/note]]
** Arachnea, Carmen, and Seras: "''Triple Rider Otome Attack''"[[note]]Arachnea spins a web trampoline and she, Carmen, and Seras jump off it, then perform flying kicks as their Spark Cores manifest a energy drill around their bodies.[[/note]]
** Showa Legacy w/Inner Moka: "''Double Legacy Cyclone''"[[note]]Both Showa Legacy and Inner Moka go through 14 golden rings, each one increasing their power with Inner Moka's aura surrounding them before performing a double kick.[[/note]]
** Showa as BLACK w/Necros as Shadow Moon: "''Twin Kingstone Flash''"[[note]]With the powers of BLACK and Shadow Moon, Showa and Necros release piercing light blasts from the Kingstones.[[/note]]
* ContinuityReboot: ''Showa & Vampire'' is considered this for ''KamenRiderShowa''.
** This story itself got one later on with ''Kamen Rider Kai'', mainly ditching the "Kamen Rider Decade of the Showa Era" gimmick for a set of original powers.
* CoolBigSis: Bast is this to Leon.
** Despite always treating him as the older one, Yuki is actually this for Yuji. No pun intended.
** Hime, Reiri, Rias and Akeno are, and always has been, this way with Shinichi.
* CrazyPrepared: Shinichi suspected that he would wind up recaptured, so he created a log of plans for his friends to follow just in case, which he gave to Inner Moka. Also Yuji in a similar fashion.
* CreepyGood: Leon is stated to be the most intimidating protaganist in the story, and most of the time doesn't mean to be scary. Shinichi, a somewhat lesser example, has his moments too. And of course, we can't forget Inner Moka.
* CrossDresser: Shinichi, when he was a little kid. His mom thought he looked adorable in dresses so his mom dressed him up in frilly dresses. He was embarrassed to see this included in the DVD.
* CurbstompBattle: Necros vs King.
** Saizou thought by gathering those with a grudge against Shinichi would overwhelm him. He thought wrong.
** [[spoiler:And in season 2, Qiao's SuperpoweredEvilSide vs. Kuyou/Blazing Fox. What makes it more shocking is that Kuyou, a ''cybernetically-enhanced cyborg youkai'', was actually ''frightened'' by Qiao actually keeping up with him.]]
** [[spoiler:Mega vs Metal Ravenborg. The cyborg beast was defeated in no time flat.]]
* CuteLittleFangs: Too many [[CuteMonsterGirl Cute Monster Girls]] to count.
* CuteMute: The "cute" part is debatable, but Chiaki can't talk due to the scientist who converted him into a cyborg taking away his speech organs. He instead communicates with signs that he pulls out of the air. Even the cast doesn't know how he does it.
** Uh [[YouFailBiologyForever vocal cords are membranes attached to the throat]] that vibrate at different speeds to facilitate tone, volume and pitch.
** What's your point? They say it was taken away.
* {{Cyborg}}: Shinichi is one, like the Showa Era Kamen Riders before him. Netto Kusanagi is also a cyborg, as is the rest of the NUMBERS.
** Implied with Dr.Gebok. Later justified when he transformed to Satan Roach.
*** [[spoiler:GIN-SHOCKER appears to be collecting some Youkai to turn into cyborgs now. It is later revealed in chapter 67 that it was Ishigami who [[UnwillingRoboticisation forcefully converted them into cyborg Youkai]].]]
[[/folder]]

[[folder: DEF]]
* [[DangerousSixteenthBirthday Dangerous Seventeenth Birthday]]: Sort of. The last few chapters of the first volume takes place on Halloween, which happened to be Misato's seventeenth birthday. During that, [[spoiler:GIN-SHOCKER unleashes its final assault on Youkai Academy, which results in the school being destroyed and Shinichi and Yuji captured]].
* [[spoiler:DarkAndTroubledPast: It's implied that a lot of the main characters are cursed with this.]]
* DarkIsEvil: BLACK 13, as he was created to [[spoiler:kill all other Kamen Riders]].
* DarkIsNotEvil: Kamen Rider Necros, whose Rider System is based on death and who has the ability to mimic the forms and abilities of various "Dark Kamen Riders," but who is most pointedly one of the good guys.
* DarkerAndEdgier: Than the previous fanfic it spun off from. Sure, it still has plenty of the humor borrowed from ''RosarioToVampire'' and a few BlackComedy and DoubleEntendre here and there, but it focuses more on Shinichi's revelations on his past sins and how he is coming into terms with them, [[spoiler:not to mention that GIN-SHOCKER has pretty much already taken over the world with several scholars, politicians, and ambassadors being some of their members. And the heroes don't even have ARMOR to back them up]]. There's a lot of swearing too, most of it from [[SirSwearsALot Yuji]].
* DatePeepers: Michiru, Misato and Ruby peeped on Hana and Yuji's date in the first chapter of ''Tails of the Liger'' via the [[Series/KamenRiderDouble Bat Shot]]. Later, Misato, Hana, and Ruby (all in disguise) were peeping on Michiru's date with Yuji, which later gets discussed and justified.
-->'''Ruby:''' "Why are we spying on them?"
-->'''Misato:''' "There's a pattern with our dates, remember? What always happens?"
-->'''Ruby:''' "[[MomentKiller GIN-SHOCKER]] [[BadDate attacks.]]"
* [[spoiler:DeathSeeker: Leon Smith.]]
* [[spoiler:DeaderThanDead: As of Tail 4 of ''Tails of the Liger'', King, Bomber, Petrifier, and Parasyte. Abyss showed them '''NO''' Mercy.]]
* DemonicPossession: [[spoiler:Or rather, Godly Possession, as Bast, the Egyptian Cat Goddess of Joy, can possess Sora due to a pact she made with her.]]
** [[spoiler:Yuji may be going through this as of Season 2-Chapter 7.]]
* DiedInYourArmsTonight: [[spoiler:Jude in Lina's.]]
* DirtyCoward: Jin, AKA Petrifier, "is considered a greedy thief among the NUMBERS, often looking out for the rewards he stands to gain. It is this behavior which does not make him well-liked or trusted. Given the chance, he'd sell his own mother."
* DirtyOldMan: Anubis. Yes, the Egyptian God of Death, Anubis.
* DidYouJustHaveSex: In Chapter 26, Yuki congratulates Netto for "finally becoming a man".
* DistaffCounterpart: [[spoiler:Kamen Rider She-Liger is this to Kamen Rider Liger. Also Kamen Rider Phantom to Kamen Rider Showa as they share the same armor.]]
* {{Dominatrix}}: Warden Anju, who has a habit of [[WhipItGood whipping her prisoners]] and keeping some of the most handsome ones as part of her harem. She is even implied to have sex with them!
* [[DoNotCallMePaul Do Not Call Me Shinji]]: See ThatManIsDead below.
* {{Doppelganger}}: After the fiasco with the mermaids, Shinichi is assumed to be one.
* DoppelgangerSpin: Storm Dragon Mega can move fast enough that he can create an "Accelerated Decoy" to take attacks while he attacks from somewhere else.
** Kamen Rider Storm can create a large number of lightning clones.
* DoesNotLikeWomen: Daichi. [[spoiler:Though he improves with his relationship with Haruhi.]]
* DontSneakUpOnMeLikeThat: Bianca does this a lot. Leon less so.
* [[spoiler:DoomedHometown: Hana's ninja village.]]
* DoubleEntendre: D takes this UpToEleven in chapter 66 when she explains to the Jager Unit what she is planning to do with Shinichi and Yuji. She doesn't even understand the Jager's reactions as she kept going.
-->"BLACK 13 should not be a problem, because my sword is bigger than his."

-->"My essence is also greater than 13's."

-->"Once I find BLACK 13, I will blast my full essence into his face."

-->"He will be on his knees as I blow him."

-->"Once I finish having my way with him, I will thrust my sword in and out of Yūji Fudō's hole. Then I will keep doing it until he submits under me, screaming as I refuse to stop doing him."

** She also does this again in the Season 1 finale during her fight with Yuji/Liger, with Dynamo [[LampshadeHanging berating her afterwards]].
--->'''D''': "Very well. It looks like I am going to have to plough you then!"
--->'''Yuji''': "Yeah, well-" ({{Beat}}) "Wait, what?!"
--->'''Dynamo''': "D, what did I say about saying something awkward in the middle of a fight?!"
* [[spoiler:DownerEnding: Shinichi and Yuji get captured by GIN-SHOCKER in the season 1 finale, the former because Ishigami/Madame Medusa [[IHaveYourWife has his]] [[TakenForGranite petrified]] [[IHaveYourWife mother]] and was on the verge of killing her, and the latter because he [[YouAreNotAlone didn't want his cousin to suffer alone]].]]
* TheDragon: General Nagazawa, being second only to the Great Leader.
* DreamSequence: During the First Term arc, Shinichi unlocked a new Rider each chapter by having a daydream (usually in the middle of battle) where he meets the Rider whose power he was going to unlock.
* [[spoiler:DreamWalker: The Great Leader of GIN-SHOCKER, JUDO, has this ability, as mentioned from Shinichi and the surviving NUMBERS. It gets confirmed during his first appearance when he visits Inner Moka in her sleep.]]
* DrunkenMaster: Yuji becomes this when [[InVinoVeritas under the influence of alcohol]], first shown in ''Tails of the Liger'' near the climax of his date with Hana. Luckily Shinichi can sober him up by striking his pressure points, as shown during their duel in the Sports Fest tournament.
* DumbMuscle: Yokoshima, given that he is a human wrecking ball and has suffered the most blows to the head while doing so.
-->"[[LampshadeHanging Why is it that everyone thinks all I'm ever good for is breaking things? Seriously, why?]]"
* ElectricTorture: D was subjected to this by Kyofu in the season 1 epilogue after failing him.
* ElegantGothicLolita: Weapon D, a.k.a. Reiko Serizawa.
* ElementalPowers: The new youkai featured in the story can manipulate an elemental power.
** BlowYouAway: Elle, a dragon, can control wind currents. Yusei's Manakyte powers allow him to control wind as well, gearing more towards speed rather than offense or defense.

** AnIcePerson: Yuki can generate and control ice, granted from her Manakyte heritage.

** PlayingWithFire: Yuji and Aki's Manakyte Blood grants them control over fire.
** PoisonousPerson: This is shown to be Mephisto's element, and [[DarkIsEdgy darkness]] being his Manakyte type.
** Also, Shinichi gains a elemental power depending on what Rider he changes to:
*** BlowYouAway: As Ichigo, Nigo, V3, and Skyrider.
*** ShockAndAwe: As V3 and Stronger.
*** PlayingWithFire[=/=]AnIcePerson: As Super-1 using the Hot/Cold Hands.
*** ThePowerOfTheSun: As BLACK and BLACK RX.
*** [[spoiler:TimeMaster: Implied to be Showa's power.]]
** Mega also has element abilities based on what form he changes into.
*** AnIcePerson: His Diamond Pegasus form grants him ice based attacks.
*** BlowYouAway: His Storm Dragon form grants him wind based attacks.
*** PlayingWithFire: His Inferno Leo form grants him fire based attacks.
*** ShockAndAwe: He can [[RideTheLightning turn into lightning to avoid attacks]] and also attack without risking damage a-la [[Series/KamenRiderBlackRX Biorider.]]
* ElementalRockPaperScissors: Showa [[spoiler:becomes Super-1 to fend off Mizore using the Hot[[note]]*:Mostly Hot[[/note]][=/=]Cold Hands during her introductory chapter.]]
* EmbarrassingNickname: "Ero-senpai" for Gin, coined by Shinichi. He even used it as a [[IShallTauntYou taunt]] to beat Gin during the Sports Fest tournament.
* EmotionlessGirl: D clams to be this, though evidence shows that it's not completely true.
* {{EMP}}: Shown with [[spoiler:Dr.Gebok]], they can harm Shinichi, and at higher frequencies, possibly kill him. Also, the Stasis Cuffs can emit EMP to paralyses cyborgs. [[JustifiedTrope Justified]], as Shinichi is a cyborg, so it can affect him.
* ElectronicEyes: A lot of the teen cyborgs have these, but Netto really shows them off whenever he uses his powers.
* EleventhHourSuperpower: [[spoiler:Shinichi acquiring the Mana Stone, a gem that has the essence of a Supreme Manakyte, during his battle with Hokuto, briefly transforming into a human/Manakyte hybrid.]]
* EquippableAlly: Bianca's chameleon, Camille, can morph into various weapons. It can even change into an [[{{BFG}} RPG]] launcher!
* EroticEating: Misato does this with a banana to tease Yuji.
* EvenEvilHasStandards: General Nagazawa berates Dr. Kyofu in chapter 65 for having D [[CurbStompBattle curb stomp]] [[KickTheDog Scanner]] and broadcasting his humiliation during a Shocker Ball game. This shows that even within GIN-SHOCKER's ranks, there are some "tamer" members.
** And earlier in the intro chapter of the ANTI-THESIS saga, Nagazawa was actually disgusted with how Gebok was manipulating Lina's feelings for Shinichi to bring him back to GIN-SHOCKER, going as far to call Gebok "a sick man".
* EveryoneGetInHere: Just about all of Shinichi and Moka's friends in Youkai Academy show up to face Phantom/Lina on their behalf.
* EverythingIsOnline: Even in the Youkai world.
* EverythingSoundsSexierInFrench: Elle Jacqueline de la Fortescue.
* EverythingsBetterWithMotorcycles: Not just better, but it just ''has'' to be included. He's a Kamen Rider; he needs it.
* EvilMinions: GIN-SHOCKER Soldiers and Cyborg Mutants.
* ExpressiveHair: Shinichi's HairAntennae can twitch around whenever his DangerSense kicks in. They can also move on their own whenever he feels embarrassed or flustered.
* {{Expy}}: D is based on Sekai Saionji from ''VisualNovel/SchoolDays'' according to Kamen Rider Bushido in her introductory chapter, albeit younger and being an (sort of) EmotionlessGirl. Oh, and not an AxCrazy {{Yandere}}.
** [[VideoGame/MegaManStarForce Gemini Spark]] in season 2 is based on Kotonoha Katsura, also from ''School Days'', according to Talismo4ever in her introductory chapter. To put it in his words: "If Bushido can make Weapon D look like a shorter Sekai Saionji, I can make Gemini Spark look like a taller Kotonoha Katsura."
** Lina Shishigami is based on Rena Ryugu from ''[[{{VisualNovel/HigurashiNoNakuKoroNi}} Higurashi]]'', despite being tomboyish and not at all girly.
** Siria Kirishima, Kiko's {{Jerkass}} older sister, is a curvier version of Eleanore la Valliere from ''TheFamiliarOfZero''.
*** It is hinted that Mimi, Kiko's other older sister, is a copy of Cattleya given [[NiceGirl how Kiko describes her]].
* FaceFault: Some characters do this a few times, mostly during the first season.
* FacePalm: Shinichi does this after Yukari announces her intentions towards Shinichi and Moka to his fellow NUMBERS.
** He later does it again chapter 50 after learning that Morrigan, Yokai Academy's guidance counselor, has the hots for Yuji.
* FalseFriend: Daichi sees Shinichi as this. He was unaware of his [[EmotionSuppression condition]] at the time, but did consider him as his only friend. Today, he doesn't even accept his apology, refuses to believe that he has changed, and even wonders why he has girls after him even after all he's done. Justified that a lot has happened in Daichi's life that caused him to be like that. But at least he's forgiven him now.
* {{Fanboy}}[=/=]{{Fangirl}}: Kurumu, Yuji, Aphrodite, and Yokoshima are fans of Shiori's works, with Yuji being the biggest. Leon is also revealed to be a fan in chapter 31, though he keeps it discreet from everyone. [[YuGiOh5Ds Crow]] is also revealed to be a fan in ''Tails of the Liger''. Ageha, Xianglian, and Tsurara are also revealed to be fans at the beginning of the Sports Fest arc. Ren Rakusa, Goemon's lover, is also revealed to be a fan in chapter 65.
** And let's not forget the Kamen Rider Fanclub for Shinichi.
* FantasyKitchenSink: This is what you get when you pair up a cyborg with a vampire.
* FinishingMove: Like his [[Series/KamenRiderDecade Heisei Counterpart]], Showa can use any of the finishing moves of the riders he transforms to. Necros possibly can use the finishers of the Dark Riders he assumes as well.

* {{Foreshadowing}}: "You can't beat me when it comes to the air, BLACK 13! Dead or alive, you will return to GIN-SHOCKER!"
** [[spoiler:"Seriously, he thinks I'm a secret agent? Next thing you know he's gonna say I was kidnapped at a young age and was brainwashed! …Why does that sound familiar?"]]
** When Sonix asks if Inner Moka is a {{Mutant}}, she retorts, "You're suggesting I'm ''human.''"
** [[spoiler:When Yuji's girls have their fantasies about Yuji's being a mob boss, Hana imagines him having ninja bodyguards. It's later revealed that she comes from a long line of ninjas.]]
* ForScience: Gebok's reason for doing what he does. Moka wasn't amused.
* ForTheEvulz: Regardless of what was done to them as children to transform them into the killing machines they are today, the remaining NUMBERS on GIN-SHOCKER's side are now doing it just for the thrill of bloodshed and the power they've been given.
* {{Flashback}}: The Family Arc has flashbacks in it, focused on the NUMBERS during their pre-BLACK 13 days. It shows they were a pretty close-knitted and organized group, with the exception of King who is still a douchebag. Also, it's another ShoutOut to RedVsBlue Season 9 since all the scenes were based on the Project Freelancer flashbacks.
* FlatWhat: Misato's reaction when Yukari loudly announces her intentions towards Shinichi and Moka. Yuki get's this reaction as well.
* FlippingTheBird: Sting Chameleon does this to Rias after she demanded the location for Shinichi and Yuji's whereabouts, telling her to "flock off".

** TheMcCoy: Misato, rambunctious and reckless party animal, always one of the first to start fights (Id).
** TheKirk: Michiru, the perky voice of reason, but easy to anger (Ego).
* FriendlyNeighborhoodVampire: Outer Moka. Let's not forget {{Karin}}, too.
* FunbagAirbag: Done with Ruby walking into Aki's cleavage in ''Tails of the Liger.''
* FunWithAcronyms: NUMBERS: Neo-Underworld Multi-Bionically Enhanced Revenge Squad. And BLACK 13: Black Legion Assault Chaos Killer 13.
** War Hunter Initiative Terminal Executioner 14, or WHITE 14 for short.

[[folder: GHI]]
* GenderFlip: Gemini Spark was originally male in ''VideoGame/MegaManStarForce''. Here he is female. See {{Expy}} above.
* GenreBusting: Action, comedy, romance, thriller, fantasy, gothic horror, sci-fi, drama, slice of life, mystery, and ecchi (with a hint of {{Hentai}} in some chapters), all rolled up in a single package.
* GentleGiant: Chiaki in a nutshell.
* GigglingVillain: [[spoiler:Qiao's SuperpoweredEvilSide.]]
* GoldenSuperMode: Legacy Mode.
** And at the finale, [[spoiler:[[InfinityPlusOneSword Higurashi]] Legacy Mode.]]
* GoodScarsEvilScars: Shinichi has a very distinctive scar over his left eyebrow. It looks like the Roman numeral for 13; XIII. The other NUMBERS also have similar scars over other parts of their flesh depending on their rank.
* GratuitousForeignLanguage: Plenty of it.
** GratuitousEnglish: Yuji and Ren. Shinichi displays a feat of speaking SurprisinglyGoodEnglish in one chapter.
** GratuitousFrench: Elle.
** GratuitousItalian: Aphrodite. Also Bianca with her ''"Ciaossu!"'', a catchphrase/greeting taken from [[Manga/KatekyoHitmanReborn Reborn]].
** GratuitousSpanish: Flannery. Yuji in one instance.
** Also, Qiao speaks Gratuitous Chinese on occasion.
* {{Goth}}: Hana is discribed as a gothic-looking girl with deathly pale skin.
* GrandmaWhatMassiveHotnessYouHave: Yuji's reaction upon seeing his great-grandmother's photo in ''Tails of the Liger''.

** Daichi and Shinichi later get this in chapter 65, the former by D and the latter by Ren.
* GunAndSword: D's weapons, the Psychic Sword and the Psychic Trigger.
* HairAntennae: Both Shinichi and Shiori sport these. They even serve as [[DangerSense warning systems]].
* HalfIdenticalTwins: Yuji and Yuki. Yuki's cool temperament matches in contrast to Yuji's more fiery nature.
* HarmfulToMinors: This is why Yukari was tricked into going out when the recording mentioned in MoralEventHorizon was shown; nobody wanted to scar another child for life.
* HavingABlast: [[spoiler:From explosive nanites]] to making toy bombs, Parasyte is this trope.
** Bomber isn't afraid to let go of the bombs in his chestplate.
* HeelFaceTurn: [[spoiler:Lina does this to the Jager Unit in the season 1 finale. As does Whriligig, since he only listens to her. The remaining Jagers follow suit after they were captured. Celeste also conducts this while defending Tamao at the Halloween Fest.]]
** [[spoiler:Rain, [[VideoGame/{{Xenosaga}} KOS-MOS, and T-elos]] also switched sides, Mikamura by her own volition and the latter two after being freed from GIN-SHOCKER's control by Mega. Though to be fair, they were never evil to begin with.]]
* HeWhoFightsMonsters: [[spoiler:How Leon views himself.]]
* HenshinHero: Self-explanatory.
* HeroicBSOD: [[spoiler:Shinichi falls into a coma after seeing the face of his first love, Lina, a psychic girl who he was tricked into killing, now revived as a cyborg and the Jager Unit commander. His mind couldn't bare the information.]]
* HeroicRROD: The Kage no Chidori left Leon incredibly weak following his fight with Mephisto. It didn't stop him from going into battle against King though.
* HeroicSafeMode: Under intense stress from what he senses as an imminent threat to his life or to that of someone he cares for, Shinichi lapses into a kind of fugue state where his fighting instincts completely dominate his body and mind and he becomes a much more brutally efficient combatant, as there is nothing else on his mind except for vanquishing the immediate threat.
* HiddenDepths: [[spoiler:Leon considers himself as a monster, considering that all of his past friends had died and he may have been factor. Yuji hadn't been with another girl, other than his sister, since the death of his first girlfriend. And Netto was previously angry at Daichi for blaming Shinichi for the actions of Gebok, which somehow reminded him of some "close-mind bigots" who scared his then-innocent mind.]]
* HomeschooledKids: Netto and Qiao where both home-schooled before meeting Shinichi. Though they aren't socially inept, perhaps due to interacting with Yuji and Yuki, both high school graduates, regularly.
* HomeMovies: For most of his life, Shinichi has been tortured and manipulated by GIN-SHOCKER, especially by Gebok. But, there was a time before that when he was happy with his family. In Chapter 31 he found a DVD his mother snuck into his bag. Discovering that it was his family's home movies he decided to share these moments with his friends during a club meeting. It shows Shinichi's time before GIN-SHOCKER, a happier time.
* HornyDevils: Kurumu, of course. Don't forget [[{{VideoGame/Darkstalkers}} Morrigan]], too.
** Shiroha is an Amazoness, a Succubus with SuperStrength.
* HospitalHottie: Hana and Michiru always have nurse costumes ready for the right time.
* HourOfPower: The NUMBERS's Spark Burst, as first demonstrated by Petrifier, can increase a NUMBER's physical and special abilities ten-fold for a minute, then it forcibly deactivates the armor and prevents transforming for one hour.
** [[spoiler:Leon, being a vizard, can create a hollow mask while increasing his abilities, but only for the maximum of seven minutes.]]
* HugeSchoolgirl: Elle stands about four inches taller than most of the male characters. Of course, Qiao, Yuki, and Aphrodite could be considered this, too.
* HulkSpeak: Implied with Whirligig in the season 1 finale.
* HumiliationConga: Todoriko has been killed, revived, curb-stomped repeatedly, had to watch his remaining teammates get killed, reduced to a janitor, repeatedly dissed by even the low-ranking grunts, and was promised a position back to the elites, only to have that snatched away when he was beaten down by D. [[spoiler:And now he's pissed and wants retribution.]]
* [[spoiler:IAmNotLeftHanded: Inner Moka believed that disarming Sonix would prevent him from using his powers, then Sonix got up and opened up his [[OhCrap chest plate.]] [[KryptoniteFactor Being a vampire with super hearing, this had a huge effect on her]].]]
* IAmAMonster: What [[spoiler:Leon]] thinks of himself. Hana, due to her additional arms, also refers to herself as a freak but Yuji denies this. Shinichi also thinks of himself as this due to the crimes he committed as BLACK 13, but [[spoiler:Leon]] makes it clear to him that ThereCanOnlyBeOne monster. Shinichi later retorts to Leon to never call himself a monster again, or else he'll kick his ass.
* IAmWho: Shinichi goes through this for the first several arcs.
* IdentityAmnesia: Shinichi is unable to remember anything about himself except for his name. [[spoiler:It later turns out it was Topper's handiwork.]]
* IdiotHair: Weapon D
* [[spoiler:[[IHaveYourWife I Have Your Mother]]: Ishigami does this to Shinichi in the Season 1 finale by holding a petrified Shiori hostage, forcing the latter to surrender for her sake.]]
* IllKillYou: Yuji does this, roaring out in outrage the name of Michiru's handler [[spoiler:Montesinos]] and describes gruesome means of ending his life.
* [[spoiler:IWillPunishYourFriendForYourFailure: Gebok once ordered BLACK 13 to abandon his team in a [[NoodleIncident particular mission]], an order which BLACK 13 disobeyed and went out of his way to rescue his comrades. Gebok saw the act as a discipline problem and decided to fix it by forcing BLACK 13 to kill his team by his own hands.]]
* ImprobableHairstyle: Yuji's hairstyle is inherited from his father, Yusei Fudo.
* ImTakingHerHomeWithMe: Aphrodite does this with anything and anyone that strikes her fancy, a la [[TropeNamer Rena]] [[{{Higurashi}} Ryugu]].
* InASingleBound
* IncrediblyLamePun: ''Tails'' of the Liger.
** Although to be completely fair, one has to wonder if it's part of the RougeAnglesOfSatin the gaiden's rife with.
* [[spoiler:InfinityPlusOneSword: Showa's Higurashi Legacy Mode[[note]]Involves Showa combining with his Cicadroid for an additional power boost. The form also includes Kamen Rider Shin's logo from when Shinichi assumed it in chapter 67[[/note]]. WordOfGod claims it to be his true final form in his post-season 1 comment.]]
* InstantExpert: Whenever Showa unlocks a new Rider, he instantly knows how to use their powers without any practice. He knows all their techniques, skills and abilities.
* InSeriesNickname: Yuji is called "Spiky-kun" by Michiru [[spoiler:and "Aniki" by Shinichi upon learning their relation]], while Netto is called "Airen" by Qiao. Rias and Akeno are called "Ri-chan" and "Ake-chan" by Shinichi. Inner Moka, as with Chrome's previous ''RosaVam'' works, gets referred to as "Moka-sama".
* InTheBlood: Yuji and Yuki both have psychic powers and draconic lineage, courtesy of their mother and father, [[Anime/YuGiOh5Ds Aki Izayoi-Fudo and Yusei Fudo]].
* InTheHood: Weapon D
* InTheNameOfTheMoon: When Showa first turned into Legacy Mode he said, "Piercing the Darkness! The Heir of the 13 Kamen Riders of Legend! Kamen Rider Showa… Legacy Mode!"
** [[spoiler:And when he reassumed it (albeit upgraded) in the season one finale, he says, "Piercing the Darkness and Cutting Through the Skies! The Heir of the Kamen Riders of Legend! Kamen Rider Showa…Higurashi Legacy Mode...! ON STAGE!"]]
* {{Irony}}: Like in canon, Moka is ranked number 13 in the midterm results, which is the same number that Shinichi is apparently designated as. This didn't slip by her.
** Another example is when Moka, a Vampire, calls Gebok, a human, a monster. Even the latter lampshades on this.
* IronicEchoCut: When Michru asks Kurumu if Shinichi is a lolicon...
---> '''Yukari''': (pointing to a [[spoiler:love hotel]]) "Let's go there."
---> '''Shinichi''': "Yukari-chan!"
---> '''Yukari''': "Just kidding."
* IronicName: Why would an eerie, pale-skinned {{Goth}} {{Cyborg}} with spider arms growing out of her back have a name that means "flower"?
* IShallTauntYou: D does this to Daichi in chapter 65 by mentioning his past of betrayal. Inverted when Lina later states that she just doesn't know when to shut the hell up.
* IsThisAJoke: Shori asks if she is being punk'd [[spoiler:after Yuji reveals that he is her nephew and that his dad is her twin brother in ''Tails of the Liger''.]]
* ItIsPronouncedTroPAY: Qiao's name is pronounced "Chee-OW" in traditional Mandarin.
* ItsAllMyFault: The FreudianTrio (look above for more info) feels this way as Yuji is targeted by GIN-SHOCKER, due to the girls defecting for his sake.
* ItRunsInTheFamily: See WouldntHitAGirl below.
[[/folder]]

[[folder: JKL]]
* JapaneseBeetleBrothers: Kamen Riders Storm and Dynamo, being a fitting Type A. [[spoiler:Bonus points for their civilian identities being ''actual'' brothers.]]
* JustInTime: Yuji shows up to save Ruby from being "interrogated" by Kurumu.
* KarmicTrickster: [[spoiler:Youkai Academy's headmaster is apparently this, as he stated that he plans to use GIN-SHOCKER's greatest weapon (Shinichi) to destroy them.]]
* KickThemWhileTheyAreDown: [[spoiler:After Shinichi falls in a coma after his encounter with Lina, Dr. Kyofu sends Weapon D after him while he's defenseless.]]
* KnightTemplar LoveInterest: Intersecting with the KnightTemplarParent and KnightTemplarBigBrother and a more unisex version of ViolentlyProtectiveGirlfriend, this love interest responds to any and all threats to their beloved's well-being with levels of violence even a SociopathicHero would appreciate or be horrified by. If the KnightTemplar LoveInterest is themselves a SociopathicHero... well, you know what to expect, but the point is that like the KnightTemplarParent and the KnightTemplarBigBrother, hurting the person this lovesick badass holds most dear is a ticket to your own painful defeat, if not death. The worse ones won't even be so merciful as to kill you quickly or even let you expire at all.
* KillerRabbit: Michiru. While she's cute and perky most of the time, remember that she's murdered hundreds of people in the past ten years of her life.
* KillTheOnesYouLove: [[spoiler:Well, not exactly "love", but #13 did think fondly of his fellow NUMBERS. When he realized what he was made to do, he went ''[[RoaringRampageOfRevenge insane]].'']]
** [[spoiler:Taken to an even higher level after being tricked into killing Lina. [[UnstoppableRage And then he began killing everything else]].]]
** Also implied with [[spoiler:Leon]].
* KissOfTheVampire: It just wouldn't be a ''RosarioToVampire'' fic without this.
* {{Kitsune}}: Aside from [[RosarioToVampire Kuyou]], of course, Qiao is a five-tailed huli jing.
** Tamao is a kitsune cub. [[spoiler:It's later revealed that she is the current incarnation of Tamamo-no-Mae, one of the strongest of all kitsune.]]
** Xianglian too. Netto stated that she is a full fledged nine-tails. [[spoiler:It is later revealed in chapter 6 of season 2 that her real name is [[http://en.wikipedia.org/wiki/Daji Daji]], a wicked fox spirit who brought an entire Chinese dynasty to its demise. This also explains her daughter's SuperpoweredEvilSide when she fought and killed Kuyou in an earlier chapter.]]
* [[spoiler:LargeHam: "I AM…THE AMAZING AND STUPENDOUS, SUPREME GENIUS OF THIS WORLD… DR. GEBOK! MY GENIUS LIGHTS UP THE SKY!"]]
* [[spoiler:LaserGuidedTykebomb: Apparently, Shinichi was designed from the very beginning to destroy all orignal Kamen Riders.]]
* LegacyHero: Shinichi has inherited the powers of the Legendary (Showa Era) Kamen Riders.
* LegoGenetics: The NUMBERS were implanted with their respective insect DNA, with Hana and Misato being the most prominent examples. [[spoiler:Celeste is also revealed to have her DNA altered, transforming her into an artificial lamia.]]
* {{Lemon}}: Rarely happens in the main series, but later chapters of ''Tails of the Liger'' have these. Justified due to FF.net's sudden crack down on lemon fics.
* LethalChef: BLACK 13. He doesn't care about flavor; only nutrients matter. His cooking could taste like sewer water for all he cares as long as it was healthy. That being said, at least Inner Moka ''tries'' to make her cooking edible.
* LightningBruiser: In a literal example, Kamen Rider Mega.
** Also Yokoshima in chapter 54 [[spoiler:when under the influence of the Dying Will Sun Flame]].
* LikeBrotherAndSister: Shinichi is this to Hime, Reiri, Rias, and Akeno.
* {{Lipstick Lesbian}}s: Natsuki Krueger and Shizuru Viola in ''Tails of the Liger''.
* [[spoiler:LivingBattery: Netto. Gebok reveals to him that his Cyber Core has unlimited power, and can destroy planets.]]
* ALoadOfBull: Genma Ishikawa, whose true monster form is a Minotaur.
* LoadsAndLoadsOfCharacters: This being a MegaCrossover, it's to be expected.
* {{Lolicon}}: In some ways, it seems Yukari is trying to manipulate Shinichi into becoming one, at least if her teasing about making him take her to a love hotel is anything to go by.
* LoopholeAbuse: Daichi finds one in his hatred for Shinichi; it's #13 he's mad at, and Shinichi, despite looking like #13, is very much not the same as the emotionless weapon that killed him and the other NUMBERS without hesitation. So Daichi tries to give Shinichi a chance based on that logic.
* LovableSexManiac: Aside from Kurumu, Misato definitely qualifies. When Yuji asked what she wanted to do on their day together, she answers "I wanna have sex with you for an entire day."
** Aphrodite and Elle have shades of this too. Xianglian also.
* LoveHotel: Yukari tries to take Shinichi to one in one chapter, and Yuji and Michiru end up in one during their date in ''Tails of the Liger''.
* LukeIAmYourFather: [[spoiler:Shiori is revealed to be Yuji and Yuki's aunt, and that in turn means that Shinichi is their cousin.]]
** [[spoiler:Also, Yuji succeeds in reuniting Shiori with her long-lost twin brother, Yusei.]]

* MachineMonotone: [[spoiler:BLACK 13/Kuro Juusan.]]

* MarshmallowHell: How Aphrodite greets people.
* [[MadeOfAir Made of Electricity]]: Kamen Rider Mega can shift into electricity to evade attacks.
* MadScientist: Dr. Gebok certinaly has the look. As does the much saner mad scientist [[FrankenFran Fran]].
* MakeMyMonsterGrow[=/=]AttackOfThe50FootWhatever: The GIN-SHOCKER Soldiers dog-pile on each other to form one GIANT GIN-SHOCKER SOLDIER. This applies to J too.
* MeaningfulEcho: When the threat of the Student Police makes itself known, Shinchi recites this to Gin, which were one of the first words he said to him: "We are the Newspaper Club. It is our job to seek out news and report it to the student body, regardless of the danger to our lives. We must be willing to risk all for the sake of our craft, because this isn't gonna be a walk in the park."
* MeaningfulName: The NUMBERS are full with these.
** Guess the color of [[ExactlyWhatItSaysOnTheTin BLACK 13's armor]].
** Bomber just loves to [[MadBomber blow stuff up]].
** The NUMBER with [[MakeMeWannaShout sound powers]] is named Sonix.
** Fitting that the [[{{Jerkass}} most arrogent NUMBER]] declare his alias as King.
** Arachnea the [[AnimalMotif spider]] NUMBER.
** Armadillo being able to curl himself into a indestructible ball.
** Petrifier gets his name from being able to conjure crystals, which he can use to trap his targets, hence petrifying them in crystal.
** Other {{Meaningful Name}}s include Yuji, which means "courageous second son"; Yuki, meaning "snow" and Netto, which is [[GratuitousGerman German]] for Internet.
** The new generation of NUMBERS called referred to as the "Jäger Unit." [[GratuitousGerman Jager]] is German for "Hunter." It is also the name of one of Liger's forms.
** WHITE 14's Rider name is Phantom, [[spoiler:as she is a ghost from Shinichi's bloody past]].
* MegaManning: As Showa, Shinichi as the ability to transform into any one of the Showa Era Riders (minus [[Film/ShinKamenRiderPrologue Shin Kamen Rider]], [[spoiler:though it's later subverted when he attained him in chapter 67. Even Shinichi doesn't know how he acquired him.]]). Showa also has an ability called "Form Ride" that allows him to let anyone use the body and powers of any Showa Era Rider of his choosing (a-la Final Form Ride from ''Decade''). The first time he used it was on Inner Moka, and she became Kamen Rider Ichigo. For Mizore, she became Denpa Ningen Tackle.
** The new Rider, Necros, also possesses this ability, but with Dark Riders.
** Kamen Rider Scanner can use the powers of those he drains, [[spoiler:as shown when he drained Mizore and was able to use her ice abilities.]]
* MidnightSnack: Shinichi went down to get something from the fridge and ends up sharing it with Mizore.
* MidSeasonUpgrade: [[spoiler:Scanner gets this in chapter 64 when he is exposed to deadly nanobots, turning him into an EldritchAbomination.]]
** Sonix also has one in Season 2-Chapter 6.
* {{Miko}}: Sora Matsuoka is one.
* MindWipe: In the season 1 epilogue [[spoiler:after recapturing Shinichi, Gebok talks to Nagazawa about "reconditioning and re-educating" him, which, when explained to Ishigami, involves [[FateWorseThanDeath wiping all of Shinichi's memories and emotions save for his training and combat experience]].]]
** [[spoiler:Also in the season 2 prologue we learn that it was Topper, an old friend of Mikogami's, that wiped Shinichi's memories of GIN-SHOCKER and made him who he was at the beginning of season 1.]]
* MissingMom: Netto's mother, [[GhostInTheShellStandAloneComplex Motoko Kusanagi]].
* {{Mook}}: GIN-SHOCKER grunts. The [[Manga/{{Bleach}} Hollows]] appear here too.
* MoralDilemma: D is hit with this in chapter 65, whether or not to keep Yuji's promise after witnessing the birthday concert he arranged for Misato, hinting she may have developed feelings for him.
* MoralMyopia: Goemon accuses Ruby of being one when she calls him out on his past deeds, reminding her that she at one point tried to destroy a city of humans. She didn't deny it, but states that she changed for the better.
* MrFixit: Yuji owns his own bike shop, "The Dragon's Den", where he fixes automobiles and builds custom bikes.
* MrsRobinson: Xianglian and Ageha, much to their daughters' chagrin. Also Warden Anju for Netto, driving it into FoeYay territory.
* MultiArmedAndDangerous: Hana’s extra arms grow from her body when her emotions aren’t kept in check or if she wills them out herself.
* MultiformBalance:
** Kamen Rider Liger:
*** JackOfAllStats: ''Zero Form''
*** FragileSpeedster: ''Jager Form''
*** GlassCannon: ''Schneider Form''
*** MightyGlacier: ''Panzer Form''
*** AdaptiveArmor: ''Torrent Form''
*** MechaExpansionPack: Zero Phoenix Mode

*** JackOfAllStats[[note]]Also a literal LightningBruiser[[/note]]: Mega Form
*** GlassCannon: ''Diamond Pegasus'' Form
*** FragileSpeedster: ''Storm Dragon'' Form
*** MightyGlacier: ''Inferno Leo'' Form
* MusicalAssassin: Daichi’s codenamed "Sonix" for a reason, you know. That reason just happens to be this trope.
* {{Mutant}}: Sora Matsuoka.
* MyGodWhatHaveIDone: PlayedForLaughs when Ren realized that she [[GroinAttack kicked the son of her favorite idol in the balls]], complete with CornerOfWoe.
* MyGreatestFailure: [[spoiler:Other than what happened with her previous Blood Warriors,]] Hime feels that she could have stayed with Shinichi on the day before his sixth birthday and might have prevented that fateful kidnapping.
* MyHeroZero: Shogo's codename is Zero.
* MythologyGag:
---> '''Saizou''': [[Series/KamenRiderDecade "You bastard! Who do you think you are?"]]
---> '''Shinichi''': "You can call me... a Kamen Rider! [[Series/KamenRiderKuuga Now watch... my... Henshin!]] Let's Ride: Showa!"
** The first Mutant Cyborgs that Showa, Inner Moka and Kurumu face are based off a spider and a bat, which are the first monsters to appear in a Kamen Rider show.
** The detective outfit that Shinichi wears when he, Moka and Kurumu confront Gin is very similar to what [[Series/KamenRiderDouble Shotaro Hidari]] would wear.
*** Later in ''Tails of the Liger'', Michiru, Misato and Ruby [[DatePeepers peeped on Yuji and Hana's date]] using the Bat Shot, a gadget used by Shotaro in ''Double''.
** Inferno Leo Mega's Overheat finisher mimics Double [=HeatMetal=]'s Metal Branding.
** Yukari's chapter is a CallBack to a ''Manga/KamenRiderSpirits'' chapter where Series/KamenRiderAmazon befriends another lonely child genius.
** In the chapter were Riderman was unlocked, a crab cyborg appeared and came for Shinichi. Now if you remember correctly, a crab cyborg was how Joji Yuki became Riderman in the first place.
** Film/KamenRiderZO mentions how Keito reminds him of another Spider Woman that he fought.
** The name of Chapter 14, "Raising Your Power to Gold", is taken from one of the songs of ''Series/KamenRiderKuuga''.
** Shinichi's bike, the Cyclone-X3 is named after the Cyclone bikes used by Kamen Rider Ichigo and Kamen Rider Nigo.
** The Liger Belt and the CAS Cards are based on [[Series/KamenRiderDenO Zeronos's]] Up Set System and Zeronos Cards.
** Netto explains in his backstory that he was turned into a cyborg by [[Series/KamenRiderFaiz Smart Brain]].
** Ren Rakusa, the female dancer who challenges Goemon, is pretty much a humanoid [[RuleSixtyThree Gender-Flipped version of]] Ryutaros, the Dragon Imagin. She even says "Kotae wa kiitenai!" word for word.
** One of the mechanics from the Dragon's Den's main branch in ''Tails of the Liger'' is named Toby Tachibana, whose "many times great-grandfather" is Tobei Tachibana, the man who supplied Kamen Riders Ichigo-Stronger their bikes.
*** Toby actually [[NamesTheSame shares the same name as his ancestor]], but prefers to be called Toby for simplicity.
** This witty exchange between Shinichi and Yuji in chapter 67 after the former gained Kamen Rider Shin.
--->'''Yuji:''' (After accidentally knocking down Shinichi) "Shin, is that you?"
--->'''Shinichi:''' "[[DeadpanSnarker No,]] [[Film/KamenRiderZO I'm Doras the Ultimate Lifeform.]] [[DeadpanSnarker Of course it's me!]]"
** Showa's pose when he assumed [[InfinityPlusOneSword Higurashi]] [[SuperMode Legacy Mode]] in the season 1 finale is a nod to Series/KamenRiderFourze's post-transformation pose, complete with [[LargeHam shouting]] [[ChewingTheScenery at the end]].
** Sera's finishing move mimics that of the Flame Kick Strike finisher of Series/KamenRiderWizard.
** Arachnea's finishing move mimics the Sparkle Cut/Xeno Clash finishers of [[Series/KamenRiderFaiz Kamen Riders Faiz and Kaixa]].
** There are also mythology gags to Chrome's previous works as well.
*** Moka cosplaying as Series/KamenRiderKiva during the Halloween Fest is a nod to ''Fanfic/RosarioToKiva''. [[spoiler:Now if you remember the plot well, Moka's inner half became Kamen Rider Dark Lady Kiva near the end.]]
* NamesToRunAwayFromReallyFast: BLACK 13
** The Black Rose Witch, if Ruby and Lady Oyakata's reactions said anything.
** For someone to be called the Fox Deity from Heaven and Hell, they must be quite scary.
** The Jager Unit, no doubt.
** [[spoiler:JUDO, the Great Leader of GIN-SHOCKER. Even ''Inner'' Moka was terrified of him during their first encounter, which says something of his power.]]
* {{Nanobots}}: Parasyte can produce tick-like nanobots that can inflict pain, explode on command or repair damage to his armor.
* NebulousEvilOrganisation: GIN-SHOCKER
* [[spoiler:NeighbourhoodFriendlyGangsters: Yuji, the heir to the [[Manga/KatekyoHitmanReborn Vongola Mafia Family]].]]
* NiceJobBreakingItHero: A villainous example. General Nagazawa explains to Kyofu in chapter 65 that it was his [[SmallNameBigEgo over-inflated ego]] and [[DudeWheresMyRespect desire for resspect among GIN-SHOCKER's ranks]] that caused an already-humiliated Scanner to [[spoiler:be (accidentally) exposed to Gebok's nanobots (which were uncontrollable to begin with, hence why he cancelled the project) and transforming him into an EldritchAbomination.]]
* NotSoDifferent: Gebok tells [[spoiler:Inner Moka]] that as much as Youkai like to look at humans as beneth them, the truth is that both humans and demons can be equally cruel, and would be willing to kill their own kind to get what they want. And from what we've seen in the resent ''RosarioToVampire'' chapters so far... he's absolutly right.
* NoblewomansLaugh: Akeno does this as she electrocutes [[VideoGame/MegaManX8 Burn Rooster]], indicating her the sadist side of her for the first time.
* NoHoldsBarredBeatdown: Compared to Inner Moka, who normally sends people of with a kick or two, Shinichi was completely merciless to the fanboys.
* NoSenseOfPersonalSpace: A lot of the girls seem to enjoy getting into the guy's personal space bubble, not that the guys mind one bit. Shinichi actually enjoys their closeness and affection to him. Leon tries, but fails, to discourage Aphrodite and Sora. Yuji and Netto, however, get pretty nervous around their girls. Doesn't really help for Netto that Qiao would like "playmates" of their own too.
* NoKillLikeOverkill: [[spoiler:What Abyss does to the four NUMBERS that attacked him and Misato/Seras. To quote, King has his body burned by {{Hellfire}} and his Spark Core destroyed and Petrifier was devoured in one gulp by Red-Eyes Darkness Metal Dragon. Specially noted to Bomber and Parasyte, whose limbs are torn apart by the Red-Eyes Black Hydra and heads eaten by said creature. [[KickTheSonOfABitch They will NOT be missed.]]]]
* [[spoiler:OffWithHisHead: Mephisto's declaration after [[MySensorsIndicateYouWantToTapThat sensing that Leon and Aphrodite have already mated]]. [[ThreatBackfire Leon repiles he'll do the same thing to him.]]]]
* OhCrap: Inner Moka gets this expression when [[spoiler:Sonix show's that he doesn't just use his WeaponOfChoice to control sound]].
** Also in season 2 when Netto accidentally blurted out his plans in the proximity of the Valkyrie Strikers.
* {{Ojou}}: Kiko and Elle.
* OjouRinglets: Kiko again.
* OlderThanTheyLook: Bianca is over 200 years old despite appearing in her twenties.
** Also, Yuji and Yuki are 20 (Hana claims that they'll turn 21 next summer) but they appear to be in their mid-late teens. Justified due to their Manakyte heritage.
* OneSteveLimit: There's an evil mermaid in the first arc named Tamao, and then Leon's adopted daughter later on.
* OurDragonsAreDifferent: Manakytes are a unique mix of human and dragons that are capable of controlling an [[ElementalPowers elemental power]], and eventually become [[PhysicalGod Supremes]], which can live for eons.
* OurElvesAreBetter: Kiko is a [[{{Warcraft}} Night Elf]].
* OurOgresAreHungrier: Haruhi, though she's pretty girly for one.
* OurVampiresAreDifferent: Misato is a cyborg based on a mosquito, so she can drain blood very much the same way Moka can. She even has her own fangs.
[[/folder]]

[[folder: PQRS]]
* [[spoiler:PaletteSwap: The Cicadroid can grant Shinichi/Kamen Rider Showa green versions of BLACK 13's energy weapons.]]
* PantheraAwesome: Kamen Rider Liger and Inferno Leo Mega
* PalsWithJesus: Leon is able to converse evenly with Anubis, and is actually embarrassed by Bast.
* [[spoiler:ParentalAbandonment: Daichi's elder sister, who actually [[{{Jerkass}} SOLD]] him to GIN-SHOCKER.]]
* PassingTheTorch: Not official since it happens in a dream sequence when the Riders pass their powers onto Shinichi.
* PervertedDrooling: Shiori does this whenever a new idea for her erotica novels passes her by.
* PhlebotinumRebel: Shinichi becomes one after [[spoiler:Gebok forced him to kill his own comrades and his first lover.]] Most of the remaining NUMBERS slowly follow suit as the series progresses, followed by the [[spoiler:Lina and the Jager Unit in season 2.]]
* PintSizedPowerhouse: Mia may be a cute little cabbit, but she can fire laser blasts that can knock General Nagazawa, GIN-SHOCKER's ''[[TheDragon Dragon]]'', '''[[{{HSQ}} across the street!]]''' Needless to say, she is now a target for Gebok's experiments.
* PlayfulHacker: Netto, despite being a {{Technopath}}. Also Yuji to a lesser extent.
* PostMortemOneLiner: From Hana: "Disappear...into the darkness".
* PowerupLetdown: In the fight where Shinichi gets Kamen Rider J's powers, they actually aren't much help at all and he ends up defeating his giant enemy with Black RX's powers.
* PreAsskickingOneLiner: From Leon: "You call yourself 'King'. Let's see how you fare against a God of Death."
* PreMortemOneLiner: From Mega: "Time for immediate de-resoultion!"
* PrideBeforeAFall: Kuyou is a [[DefiedTrope defied version]] of this. From being curb-stomped by Showa during the First Term Arc to being beaten by Leon near the end, he still refuses to admit his defeat. [[spoiler:Even after being converted into a powerful cyborg youkai, he was curb-stomped ''again'' by Qiao's [[SuperpoweredEvilSide dark side]] in season 2, yet he continues to defy it (though to be fair, he was doing a strategic retreat but Qiao followed him).]] Ishigami even lampshades this beforehand.
-->'''Ishigami:''' "Kuyou-san, you are going to find yourself in an early grave with that attitude."
* PsychicPowers: Like their mother, Yuji and Yuki are Psychic Duelists. Qiao also has usage of telekinesis. Phantom and Reiko also has access to psychic powers.
* PsychoExGirlfriend: A few of the characters, notably Daichi and Michiru, seem fond of calling Lina this. She isn't crazy though, just very determined.
* RedOniBlueOni: Hana is the Blue Oni to Michiru and Misato's Red.
** Yuji is the Red Oni to Yuki's Blue. See SiblingYinYang below.
* [[RagtagBunchOfMisfits Ragtag Army of Misfits]]: It's even pointed out several times in the story.
* RescueArc: Season 2 starts off as this, coupled with RoaringRampageOfRevenge from the former NUMBERS. As Yokoshima puts it in season 1's epilogue:
-->"GS has messed with us our whole lives. We were taken from our families, corrupted and made into weapons. Well, we're going to show them what happens when they mistreat their weapons."
* RescueRomance
* {{Revenge}}: Shinichi wants to get back at GIN-SHOCKER for what they did to him and the other NUMBERS. His friends, Yuji and Inner Moka especially, are willing to back him up.
* RichBitch: Siria, Kiko's eldest sister, in sharp contrast to Kiko's SpoiledSweet. In fact, she even managed to ''scare'' Kiko when she was introduced. Netto even explains that her personality is what caused ''her own'' fiancee to flee for his life, and the whole trope gets lampshaded afterwards.
* [[MechaExpansionPack Rider Expansion Pack]]: Suzaku, a phoenix-like mecha, can combine with Liger Zero to form Liger Zero Phoenix Mode.
** [[spoiler:Breaker possesses a large Centipedroid Unit that can unite with with from the waist-down, also Showa possesses a Cicadroid that gives him [[PowerGivesYouWings energy wings]] and [[PaletteSwap green version]]s of BLACK 13's weapons.]]
* RidiculouslyCuteCritter: Mia, the [[TenchiMuyo Cabbit]].
* SacredFirstKiss: As early as Chapter 7, this happens between [[spoiler:Shinichi and Inner Moka. She later explains [[BreakingTheFourthWall to the reader]] that she was impressed with Shinichi's powers so far that she kissed him as a reward, and is waiting to see what else he can do before decides to clam him for her own]]. Later, Outer Moka has her own first kiss with Shinichi. And Bast tricks Sora into giving her's to an unconscious Leon. And Kurumu and Mizore finally get theirs in chapter 30.
* SayMyName: [[spoiler:Moka and Yuki in the finale, after Shinichi and Yuji surrender themselves to GIN-SHOCKER.]]
** [[spoiler:Also in the finale, Lina/Phantom does this after Jude/Atlas defends her from Whiplash's sword.]]
* SelfMadeOrphan: [[spoiler:Goemon slited his father's throat after suffering from too many beatings.]]
* SexySaxMan: This is Yuji as he’s played the saxophone piece of the song "Brick Ballades" from ''Anime/TheBigO''.
* ShellShockedVeteran: Some of the renegade NUMBERS show this. Shinichi most of all.
* ShapingYourAttacks: Both of Yuji/Liger's [[CombinationAttack combination attacks]] involved shaping the attack into a Dragon and Lion, in that order.
* SheIsAllGrownUp: Well, not really "she". This is how Hime and Reiri react to how much Shinichi has changed. He's not a crybaby anymore and he can fight monsters with immense skill and strength. Clearly, pretty shocking, even after ten years of not seeing each other. They saw someone who cried a lot when he was six crush the skull of a monster. Reiri even suggested to Hime that they make him into a Blood Warrior.
* SheIsNotMyGirlfriend: What Daichi says about Haruhi. Justified due to his girl problems.
* {{Shinigami}}: Kamen Rider Necros' appearance is based on Anubis, the Egyptian God of the Dead. It also turns out that Leon is literally a Shinigami himself.
* ShoutOut: [[ShoutOut/ShowaAndVampire Now has its own page.]]
* ShownTheirWork: At every end of the chapter, one of the main characters explain the history and powers of the Kamen Riders featured in the fic, as well as the arsenal, as an {{omake}}.
* SingingInTheShower: Yuji does this when bathing alone.
* SinisterScythe: Leon Smith's Zanpakuto, Kage no Shi, takes the form of one.
* SirSwearsALot: Yuji, full stop. Lampshaded and discussed by Shiroha and Kurumu in season 2, chapter 2.
* SixthRanger: Yuji Fudo, a.k.a. Kamen Rider Liger; Leon Smith, a.k.a. Kamen Rider Necros; and Netto Kusanagi, a.k.a. Kamen Rider Mega. Most of the NUMBERS soon follow suit.
** [[spoiler:And we have two new sixth rangers in the season one finale in the form of Lina/Phantom and Whirligig, followed by the rest of the Jagers come season 2.]]
** [[spoiler:And speaking of season 2, we now have Yuki Fudo, a.k.a. Kamen Rider She-Liger, taking her brother's mantle.]]
* SlasherSmile:
--> ''Moka-sama stared back at the Soldier with one of her normal stoic stares. Suddenly, she started to grin, showing her frighteningly sharp canines, "Hello."''
* SmallNameBigEgo: Professor Kyofu, who is egotistical enough to mock those he looks down on when he believe they've failed at something... even when they really didn't. Then it suddenly comes back to bite him in chapter 65 by Nagazawa.
* SnakePeople: Ms. Ririko, being a lamia, of course. [[spoiler:Celeste is also one as well, though through [[LegoGenetics artificial means]].]]
* SneezeCut: [[VisualNovel/SchoolDays Makoto Ito]] gets one in chapter 62 by Shinichi after he called him "some asshole who cheats on his girlfriend to sleep with other girls". Also doubles as a TakeThat.
** Yuki also gets one during the Sports Fest arc after Shinichi questioned who was the "genius" that designed the elimination race in the first place.
** Gin also gets one in an earlier chapter.
* SpiderTank: [[GhostInTheShellStandAloneComplex Tachikoma-kun]], but he's cute.
* SplitPersonality: Aside from Moka, the Abyss King to Yuji.
** [[spoiler:BLACK 13/Kuro Juusan to Shinichi.]]
* SpoiledSweet: Kiko Kirishima seems like your typical RichBitch, being the Big Diva on Campus before Moka's arrival and having many boys wrapped around her fingers. She even has a penthouse suite at the top of the girls' dorm. There is, however, a nicer side to her, shown when she defends {{Karin}} from bullies, and then from [[VideoGame/MegaManX1 Sting Chameleon]]. Her eldest sister... [[RichBitch not so much.]]
* StalkerWithACrush: All four main Riders have at least one. Mizore for Shinichi, Sora for Leon, Elle for Netto (though she is a subversion as she is seeking a worthy mate, whom she later finds in Netto), and [[spoiler:later [[Manga/FairyTail Juvia]] for Yuji.]]
* TheStationsOfTheCanon: This story takes some of the original parts of the manga, tears them up, and makes something new out of them. For example, during Kurumu's intro chapter, a Spider-Borg and Bat-Borg come to retrieve Shinichi, and both girls attempt to escape them. In Gin's chapter, Shinichi was apparently three steps ahead of him when the werewolf attempted to make him look like a shameless pervert. In another chapter, the fanboys from the anime were shown in spite of part of the plot being based on the manga.
* StatuesqueStunner: Elle.
* StealthHiBye: Leon does this often.
* StepfordSmiler: To an extent, as Michiru tries to stay positive despite her internal pain. But her cheerfulness is justified and reinforced, thanks to the effort Yuji puts in to always making her happy.
** [[spoiler:Netto is hinted to be in the same boat as Michiru.]]
* TheStoic: In the ''Showa & Vampire'' {{prequel}}, Project NUMBERS, #13 (Shinichi's former self) was depicted as cold, logical and rational. He never could express emotions. Leon himself is already stoic, but unlike #13, he is capable of showing emotions.

* SuperpoweredEvilSide: [[spoiler:When in the presence of another Kamen Rider, Shinichi's "Anti-Rider" protocols activate, transforming him into a black-armored berserker mode called BLACK 13, which will stop at nothing to kill the other Rider and will even tear apart anything or anyone perceived to be in his way. But Kurmuru's Charm ablilty seemed to disable that programing. Well, not anymore.]]
** [[spoiler: When one of Yuji's loved ones is harmed, an alternate personaility named Abyss takes control, using the powers of the Red-Eyes Black Dragon to destroy those responsible before giving Yuji back the reins.]]
** [[spoiler:Qiao is also hinted to have one, as shown in chapter 4 of season 2 during her fight with Kuyou.]]
* SuperEmpowering: As a side effect of his MegaManning ability with the Showa-era Kamen Riders, Shinichi can temporarily transfer the powers of one Showa Rider into another person, creating a "Form Ride" that transforms said person into a replica of the Rider in question. As he's so far only done it with the members of his harem, this has created plenty of [[RuleSixtyThree Gender-Flipped Kamen Riders]] to fight alongside Showa.
* SuperMode: Aside from Showa's Legacy Form, [[spoiler:Kuyou, as Blazing Fox, also has a super mode where he generates four additional artificial tails for a total of nine.]]
* SuperSpeed: BLACK 13. He's so fast he's like a blur of motion. [[spoiler:Leon Smith also has this, leading the girls to wonder if he is a werewolf]]. Then we have [[ZoidsNewCentury Lightning Saix]] who's really fast, but Liger's Jager form counteracts this. Zero, according to Inner Moka, can move at bullet speeds. Then there's Mega's Storm Dragon form, who can move so fast he can be at two places at once. Elle, being a Sky Dragon, can break the sound barrier. Yusei can also move at blurring speeds.

* ThanksForTheMammary: Yokoshima did this to Kurumu once during the Sports Fest. [[ArmorPiercingSlap She didn't appreciate that]].
* {{Technopath}}: Netto has the abliity to manipulate any type of machine.
* TemptingFate: Yukari and Shinichi seem to have made it through their "date" perfectly all right. Just as they start celebrating... the NUMBERS that didn't defect to Shinichi's side attack.
* ThatCameOutWrong: Happens every once in a while, mostly with Shinichi.
** For example, in Yukari's chapter:
--> "I don't like to be attacked. Now, if you don't behave I might be forced to give you a spanking...({{Beat}}) And I just realized how dirty that sounded once I said it out loud."

--> "You little...you used magic on me, didn't you? Alright, I am so gonna get a thick stick and pound your ass with it! ({{Beat}}) OK...Now people are so gonna think I'm a lolicon pervert."

--> "I'll always cover the back of a sweet, little girl. And yeah, I know how it sounded. Lay off."

** Happens again in Chapter 15, with LampshadeHanging:
--->"Now I think this will be my one and only ride. I just love the feeling of something big and hard vibrating between my legs."({{Beat}}) [[LampshadeHanging 'What's wrong with me?' Shinichi thought. Did he just not have a language filter?]]
** Another example is in Chapter 16 when he meets Ruby:
--->"Well, I’ll just have to take a big pole and shove it up your ass!" ({{Beat}}) "O…kay…That sounded a lot dirtier than I intended."
* ThatManIsDead: Shinichi claims this as the reason why he won't use his birth name (Shinji), as GIN-SHOCKER already robbed him of his humanity (and by extension, his life as a human being). Though he lets this slide with his mother and his childhood friends.
* ThirdPersonPerson: Juvia.
* ThirteenIsUnlucky: Shinichi, ''big time''.
* ThisIsUnforgivable: Moka and the others' reaction when they find out what GIN-SHOCKER has been doing to children.
** They didn't say it outright, but it's clear that Ageha and Tsurara also feel this way after Shinichi confirms to them about being a cyborg.
** Also how the ex-NUMBERS react upon learning about Kuyou and how he ran the school.
* TimeToUnlockMoreTruePotential: Shinichi getting his Rider powers unlocked and awakened.
* TinyGuyHugeGirl: Netto is the Tiny Guy to Qiao, Kiko and Elle's Huge Girl. Also Leon and Aphrodite to a lesser extent.
* TomboyAndGirlyGirl: Lina is the tomboy to Inner and Outer Moka's girly girl, despite Inner Moka being an ActionGirl.
* TooLongDidntDub: Some basic Japanese phrases didn't get translated into full English and the [[JapaneseHonorifics honorifics]] are into full play in this fic.
** [[JustifiedTrope Though it makes sense since the story takes place in Japan]], [[FridgeBrilliance and it wouldn't sound like they're in Japan without them.]]
* TookALevelInBadass: [[spoiler:Yuki becoming Kamen Rider She-Liger in season 2.]]

** "You should try getting shot at by your own father, slashed at by one of your uncles, and being blown up by one of your other uncles' rocket launcher as training. That'll really make you piss your pants for a while."
** Also justified with the NUMBERS and Jager Unit.
* TransformationTrinket: Necros' Rider Keys and Mobirider. Let's not forget the Legacy Driver that lets Showa become Legacy Mode. Then we have Yuji's Liger Belt, Netto's belt and the NUMBERS' Spark Cores which is the source of their power and what they use to transform.
* TranshumanTreachery: By Kamiyami, Kamen Rider King, who claims that he chose to become what he is now because he desired power above all else. If that meant becoming a cyborg and effectively selling out the human race... so be it.
** Jack Cisco, a.k.a. Lightning Saix, is another example as he is willing to sacrifice his humanity just to walk again.
** [[spoiler:Kuyou is starting to walk down this path as well after losing to Shinichi.]]
* TriggerHappy: Bomber just LOVES unleashing lead from his machine guns.
* TronLines: Appears on Netto's eyes when ever he uses his technopathic powers.
** And Kamen Rider Mega sports these on his chest armor.

* UnexpectedSuccessor: [[spoiler:A motorbike mechanic like Yuji would be the last person people would expect to become a mafia boss.]]

* UnwillingRoboticisation: The NUMBERS and the Jager Unit in general. Also, it is revealed in chapter 67 that [[spoiler:Ishigami (now Madame Medusa) forcefully converted Shinichi's past enemies into cyborg Youkai.]]
* VaginaDentata: What Snap Trap, General Nagazawa's cyborg beast form, looks like.
* VoluntaryShapeshifting: For Qiao, being a huli jing, this is her specialty, being able to completely mimic Misato and Yuji.
[[/folder]]

[[folder: WXYZ]]
* WakeUpGoToSchoolSaveTheWorld: Since the main characters all go to school and are going up against an evil terrorist organization that seeks to take over the world, this trope fits the bill. It explains Shinichi's resolve after he discovers much of his past in GIN-SHOCKER, and being completely aware of what they had done.
* WallCrawl: Kamen Rider Mega can cling to walls and ceilings. Arachnea can do the same, considering that she is based on a spider. Ironically, he does this more often than she does.

* WholesomeCrossdresser: In Shinichi's defense, people can barely tell the difference between boys and girls at very young ages.

** To an extent, Yuji with his mild hydrophobia as he always refuses to go in a pool or oceans.
