->''"I... did it... for the lawls."''

In the ending moments of the [[LightNovel/FateZero Fourth Holy Grail War]], certain people took a different tack to resolve the problem of the tainted grail. As a result, there was no fire that consumed Fuyuki City.

Ten years later, Shirou Urobuchi finds himself having the most harrowing day of his life. He is chased by a blue haired spearman for no reason, and his attempt to counterattack gets the school burnt down. After his life was saved by a white haired man dual wielding swords, he manages to get home, only to find Illyasviel von Einzbern nee Emiya waiting for him. She's giving him an early birthday present, her virginity. The red-haired, Internet-savvy, hungry-for-Sakura-Matou teenaged boy accepts, and soon finds his fate tied to the Emiya family, just as the Fifth Holy Grail War begins...

''[[http://www.fanfiction.net/s/6859461/1/I_Put_On_My_Robe_And_Wizard_Hat I Put On My Robe And Wizard Hat]]'' is a ''VisualNovel/FateStayNight'' FanFic written by Ol'Velsper. It is an attempt to reimagine the Fifth Holy Grail War [[FollowTheLeader in the same vein]] as the [[FanFic/TheKeyToASuccessfulInterview Interview-verse]] [[FanFic/BeautifulDestroyerSailorMoon fics]] of The Sage of Toads. That means making people GenreSavvy, OneOfUs, and, most importantly, CrazyAwesome.

The {{sequel}}, ''[[http://www.fanfiction.net/s/7083560/1/ Apostles in Leather Pants]]'', takes place not long after the first story and reimagines ''VisualNovel/{{Tsukihime}}''. There is also a side story, ''[[http://www.fanfiction.net/s/6931474/1/Reflections_of_the_Kaleidoscope Reflection of the Kaleidoscope]]'', that contains some what-ifs and some crossovers.

* BrainBleach: This is Lancer's response to the information provided to him by the Grail when Shirou asks his last question.
* BrokeYourArmPunchingOutCthulhu: Type 1. [[spoiler:Shirou Urobuchi (The Younger)]] [[HeroicSacrifice sacrifices]] himself to stop Angra Mainyu's manifestation, but ends up [[spoiler:trapped in the Holy Grail and finding out he only delayed the Evil Divine Spirit.]]

* CarFu: Rider and Saber duel on motorbikes, and then later, Rider tries to run Shirou and Saber down with a train.
--> '''Shirou:''' [[MultiTrackDrifting MULTI-TRACK DRIFTING!]]
* ClapYourHandsIfYouBelieve:
** Rin believes that [[VideoGame/{{Slayers}} Lina Inverse]] is real. Thus, when she finds the info on TheOtherWiki, she can't help but laugh as she finds the MagicalIncantation to the [[FantasticNuke Dragon Slave]] spell. She then uses the spell to blow up the Matou household after Archer rescues Sakura.
** When Shirou is fighting Myrddin, Shirou realizes that because they're in his mind he can do anything he imagines and screw the rules of reality. Acting on that belief allows him to win.
** Invoked by Ren Urobuchi. He tells Herakles to answer his prayer if there's any part of him that's really a god, and save the girl with them. This empowers Herakles enough for him to break his paralysis.
* CombinationAttack: Medea and Cú Chulainn combine their powers to use the [[VideoGame/{{Suikoden}} True Sun Rune]] on a horde of zombies.
* {{Crossover}}: Half of the Franchise/{{Nasuverse}}. Also, [[Anime/PuellaMagiMadokaMagica Homura Akemi]] cameos in the epilogue. Ol'Velsper says this is a prequel to her appearance in his other work, ''Lyrical Chronicles''.

%%* DeconstructionFic.
* DelayingAction

* DyingDeclarationOfLove: [[spoiler:Saber]] declares her love to Shirou as she's about to [[spoiler:hit him and Angra Mainyu with a blast from Excalibur]].
* EnemyMine: Like with Caster in ''Fate/Zero'', the Grail War is put on hold and everyone teams up to deal with Zouken.
* EquivalentExchange: Archer's ability seems limited to exchanging artifacts with similar histories. He can trade up for more potent Noble Phantasms by offering his personal Noble Phantasm: [[spoiler:The Jewel Sword Kischur Zelretch Schweinorg]].
* EvilTwin: The Einzberns send in a [[Manga/FateKaleidLinerPrismaIllya dark-skinned version of Ilya]] as their representative in the Fifth Holy Grail War.

* ForWantOfANail: Archer-Urobuchi picks up the slack when Rin Tohsaka misplaces the gem stone that would serve as the catalyst to call Archer-Emiya.
* FromBadToWorse: Zouken's familiars have started a zombie apocalypse in Fuyuki and Zouken is making his play for the Greater Grail. Everyone fighting together are barely holding him off. Then, [[spoiler:Angra Mainyu successfully fully manifests]]. Which results in Alaya sending in a Counter Guardian in [[KillEmAll full-combat mode]].
* FusionDance: Power Booster-type. Caster temporarily absorbs Saber, whose part-dragon nature upgrades Caster's Colchis Dragon spell from a drake to a full-blown dragon.
* {{Geas}}: Gilgamesh uses a couple of Zouken's crest worms to put him under a self-contract geas.
* GirlOnGirlIsHot: Archer decides it's been a fantastic Grail War, and makes no move to separate them, when he sees Rin and Sakura fall into a compromising position.

* HappilyMarried: Kirutsugu and Taiga.
* HeroicSacrifice:
** [[spoiler:Caster]] pins down [[spoiler:Angra Mainyu]] so he'll be hit by what's apparently a falling holy mountain, and gets hit as well. She releases Saber from their Fusion Dance and sends her away with some appropriately dramatic final words.
** Soon after, [[spoiler:Shirou]] grabs [[spoiler:Angra Mainyu]] in a grapple lock so Saber can hit them with Excalibur.
%%** [[spoiler:Lancer]]
%%** [[spoiler:Berserker]]
* HiveMind: Zouken's worms are connected this way.
* HoldTheLine: A company of [[spoiler:Iskandar's soldiers]] distract the Counter Guardian long enough for Archer to close the hole the CG just blew in the Reality Marble and take him away from the fight. Overlaps with Delaying Action.
* IdiosyncraticEpisodeNaming: All chapters except for the first and the last three are named after ''TabletopGame/DungeonsAndDragons'' spells; specifically, Wizard or Sorcerer spells.
* InSpiteOfANail: Despite no fire, Avalon is inserted into Shirou [[spoiler:in order to keep him from being overwhelmed by the awakening of his magic circuits.]]
* InstantExpert: The Noble Phantasms Archer creates give anyone who wields them the knowledge of how to use them properly.
* InvisibilityCloak: One of the functions of Tarnhelm is to allow the wearer to become invisible.
* {{Irony}}: Kuro-Ilya believes the Urobuchis to be nobility and calls Shirou "Sir Urobuchi," to which Shirou protests, "I'm not a Sir." Later, Saber knights Shirou under the authority of King Arthur, meaning he now is, in fact, a Sir.
* ItAmusedMe: Shirou tells Lancer he asked about Rei Ayanami "for the lawls," though it's really more a matter of his thoughts going haywire at the time. Later, Myrddin claims to be sending giant rocks at Shirou "for the lulz"; in actuality it's a combination of this and to test the worth of the man Arturia is serving.
* JustInTime:
** Kuro-Illya and Herakles arrive just in time to save Ren Urobuchi, Saber, and Illya from a horde of zombies.
** Miyu accidentally triggers a Servant summoning spell, just in time to call forth a replacement Rider-class who takes down the zombies chasing her. [[spoiler:Not just any Rider class, either, but Iskander from the Fourth Grail War.]]
** [[spoiler:Iskandar]] arrives just in time to save Saber from being squeezed to death.
* LaughingMad: Shinji in a moment of lucidity after he's been [[spoiler:turned into a zombie]].
* MafiaPrincess: As per canon, Taiga Emiya nee Fujimura is the granddaughter of a Yakuza boss.
* ManaDrain: The Matou magecraft is based around absorption, so Sakura and each of Zouken's worms can drain od and prana from people nearby. Enough worms in one place can even paralyze a Heroic Spirit.
* MurderTheHypotenuse: When Ilya dumps him, Shinji orders Rider to kill Shirou. Unfortunately for him, he doesn't know that Shirou is a Master or that Archer makes use of Medusa for his own plans.
* MySkullRunnethOver: Because all of the worms are connected through the Hive Mind, when one gets shot with an Origin bullet they all die. Shinji is also connected and experiences all of their deaths simultaneously. It's more information than he can handle and drives him insane. Shirou later specifically compares it to a [[http://www.webopedia.com/TERM/D/DDoS_attack.html DDoS attack]].
* NiceJobBreakingItHero: Kiritsugu sabotaged Fuyuki's ley lines to prevent the Greater Grail from manifesting. Unfortunately, he neglected to tell anyone else he did. So, when Archer enacts his plan to ascend Medusa and exorcise Zouken from Sakura, the damaged ley lines overload, causing the [[ApocalypseHow earthquake]] that nearly levels Fuyuki and [[ZombieApocalypse unleashing Zouken's familiars]] into the populace.
* OhCrap: Shirou's reaction to the opening move of Myrddin's training.
* PersonOfMassDestruction: Counter Guardian EMIYA completely destroys around 250 copies of Rho Aias in the first shot, then breaks through the rest more gradually once he's slowed down.
* RemovingTheHeadOrDestroyingTheBrain: The zombies have to be killed this way.
* RousingSpeech: Shirou adapts the [[http://www.youtube.com/watch?v=d6wRkzCW5qI 40 Inspirational Speeches in 2 Minutes video]] to convince Kuro-Ilya to fight against Zouken's plot. It captivates Saber, as well, to the exasperation of those who know what Shirou's doing.
* RuleOfFunny: {{Discussed|Trope}} by Archer and Rider, and mentioned by name by the former, when Rin defies physics to end up with her head in Sakura's cleavage under Sakura's already too-tight shirt when they fall.
* SealedEvilInADuel: Implied to be [[spoiler:Shirou Urobuchi]]'s fate in the epilogue.
* SelectiveMagnetism: Shirou's first command spell to "get over here," strengthened by Ilya having somehow cut off Saber's magic resistance at the time, forces Saber to remain wihin a certain distance of Shirou. Initially PlayedForLaughs, but {{exploited|Trope}} during their first battle to get Shirou safely onto the motorcycle from the sidecar.
* SetRightWhatOnceWentWrong: [[spoiler:Heroic Spirit UROBUCHI]]'s goal, even though his original timeline would still exist. Apparently [[spoiler:Fuyuki City was totally destroyed in his Fifth Holy Grail War and Rin died at the hands of Zouken]].
* SheIsAllGrownUp: Ilya has a teenage body in this storyline.
* ShoutOut: The other main ingredient besides RuleOfCool.
** The third chapter starts right out with Archer saying [[LightNovel/{{Oreimo}} "My little Master can't be this lame!"]]
** Archer demonstrating his Reality Marble to Rin has him adapting the [[Advertising/TheManYourManCouldSmellLike Isaiah Mustafa Old Spice commercials]].
** Shirou's family name is from Gen Urobuchi, the writer from Creator/{{Nitroplus}} responsible for ''LightNovel/FateZero''.
** To ''Anime/PuellaMagiMadokaMagica'': Shirou's father Ren often mutters something about heat death for some reason. Myrddin says he won't make Shirou wear a Magical Girl outfit and save the Universe from heat death.
** Rider stumbles upon a [[Anime/{{FLCL}} yellow Vespa]] in her search for a motorbike.
** While executing his plan to rescue Sakura, Archer uses [[Franchise/MetalGear the codename Snake and has a cardboard box with him]]. He also tells her, [[Franchise/{{Terminator}} "Come with me if you want to live."]]
** ''[[FanFic/MyImmortal What the hell are you doing, you motherfuckers?!]]'' Used twice.
** Shirou's mindscape experience is evocative of a situation in ''Manga/{{Bleach}}'': In a cave, a trolltastic figure is helping the hero in the frame of three "lessons." Lesson Three is basically a "Try not to die" test. The hero is losing badly when the setting changes arund him and a vision of a helpful third party appears in front of him. The new figure gives him the mindset to properly use his power, the setting returns, and the hero defeats the teacher.
** Myrddin makes a reference while testing Shirou. He uses the lyrics to [[Music/{{Queen}} "We Will Rock You"]], ending with "Queen Sign" and the chorus, as an aria for a spell that [[{{Pun}} sends rocks]] of all sizes at Shirou.
** Shirou responds in kind when he comes back from the "Tiger Dojo." He starts ignoring physics (see Clap Your Hands If You Believe above) and Myrddin gleefully asks what's going on:
--->'''Shirou:''' ''[[VideoGame/{{Touhou}} Hax Sign]]: [[Webcomic/TouhouNekokayou You Just Plain]] [[PrecisionFStrike Fucking]] [[Webcomic/TouhouNekokayou Lose]]''.
** Lancer appears and interrupts Kuzuki in the style of Music/KanyeWest's interruption of Taylor Swift at the Grammys.
** [[LeeroyJenkins “LEEEEEERRRROOOY JEEEEEEENNNKKKIINNS!”]]
** While defending his reasons for holding back on his Reality Marble, Archer laments on how some of his friends would react. [[VideoGame/{{Touhou}} The Witch]] would flay him alive, [[Literature/{{Discworld}} The Librarian]] would sic the worms on him, and the last would [[Anime/ReadOrDie slice him to pieces with paper]].
** To ''Manga/RanmaOneHalf'':
--->"I'm...um...Shirou Urobuchi," The white haired man nervously chuckled. He closed his eyes as he dipped his head. [[TheStationsOfTheCanon "Sorry about this?"]]
** To convince Saber to fight with him (and not stab him in the back), Shirou says that Saber shouldn't believe in Kititsugu, but [[Anime/TengenToppaGurrenLagann "Believe in me that believes in Kiritsugu!"]] To emphasize the shout out, Shirou then copies what Simon says when he declares that he isn't Kamina.
--->"Who the hell do you think I am? My name is Shirou Urobuchi!" His hands lashed out and grabbed onto the king's own, causing a spark to run up Arturia's hands. Only Irisviel had really been touchy with her during the Fourth War. "Not Kiritsugu Emiya! I'm me! Shirou the Wizard!"
** After Shirou tells Caren about his life, Caren asks what answer Shirou got from it. His answer is [[Franchise/TheHitchhikersGuideToTheGalaxy forty-]][[JustForFun/FortyTwo two]].
** After Kuro-Iliya mentions to Miyu that her water magic hasn't developed enough to heal people, Miyu asks if Kuro-Ilya [[Manga/FullmetalAlchemist "ever thought of clapping and then slamming your palms into the gro-"]]
--->'''Kuro-Illya:''' Alchemy. Does. Not. Work. That. Way.
** When Taiga and Kiritsugu are riding in [[spoiler:Gordius Wheel with Iskandar]], Taiga says, "Bring me closer so I can hit the with my sword!", a reference to ''TabletopGame/{{Warhammer 40000}}'s'' "Drive me closer, I want to hit them with my sword!"
** "[[Webcomic/{{Hiimdaisy}} And no one ate dinner that night]]."
** To ''[[VideoGame/TheLegendOfZeldaI The Legend of Zelda]]'': As they're preparing to charge on Zouken's army at dawn for the final battle, Archer comes up to Shirou and says, "Hey, it's dangerous to go alone. Here, take this," referencing a meme that arose from the game.
** To ''VisualNovel/FateStayNight'': Lancer says he refuses to die when he's killed.[[labelnote:*]]"People die when they are killed" is an [[MemeticMutation infamous]] mistranslation of one of Shirou's lines in ''Fate/stay night''[[/labelnote]] His Battle Continuation skill backs up his claim.
** The epilogue contains a "score card" of Shirou's and Archer's achievements, and half of them are references:

** Waver notices Miyu is carrying a copy of ''VideoGame/BattleMoonWars'' and offers to play with her after things settle down. Later, after [[spoiler:Iskander]] leaves Waver in charge to make sure things run smoothly, Waver says "...well, I'll be over here trying to get us a Battle Mastery." Then, in the epilogue:
--->"Super Servant Wars" stage – Battle Mastery attained!
:: :It should be noted that ''VideoGame/BattleMoonWars'' is a fan-made ''Fate/Stay Night'' game, based on ''VideoGame/SuperRobotWars'', among other things, so this is a double reference.
* ShownTheirWork: The author gives appropriate nods throughout the FanFic to the Servants' respective legends, as well as [[AllInTheManual Nasu's data books]].
* SomethingOnlyTheyWouldSay: Kuro-Ilya and Herakles test Shirou's claim that he's Ren Urobuchi's son by asking him what weapon his father uses. Shirou guesses his dad made the [[AwesomeButImpractical chainsaw naginata]] they always talk about, which is the right answer.
* SparedByTheAdaptation: Implied for all the innocents who would've died in the great fire that didn't happen in the current timeline. Played straight for Kiritsugu and Bazett, who are also alive.
* SuspiciouslySpecificDenial: Shirou finds Myrddin's claim of what he won't do to Shirou to be suspiciously specific.
* SwordPlant: Saber plants her sword in the floor after her initial strike at Kiritsugu.
* TakingYouWithMe: [[spoiler:Shirou]] gets stabbed by [[spoiler:Angra Mainyu]] and is going to die anyway, so he grabs his attacker so Saber can hit them with Excalibur.
* ThisWasHisTrueForm: Turns out [[spoiler:Heroic Spirit UROBUCHI]] was using the Jeweled Sword of Zelretch in order to take the form of [[spoiler:Counter Guardian EMIYA]]. When it [[spoiler:becomes a Broken Phantasm due to the overflow of mana]], he reverts to his natural form and loses access to numerous abilities.
* ThreeLinesSomeWaiting: In the first stage of the final battle, there are three groups of protagonists: Rin, Sakura, Archer, and Medusa-Saver; Ilya, Taiga, Bazett, Lancer, Caster, and Kuzuki; and Shirou, Saber, Kiritsugu, and Caren. While the third group are convincing Kuro-Illyasviel and Herakles to join them, the second group enlist the help of 15 yakuza men from Taiga's grandfather. The first and second groups meet up at the final battle site, but then Lancer and Archer split off from the group to act as a vanguard, so there are still three lines at that point. There is some waiting between scenes for each group, and some crossover between the first and second's points of view.
* TitleDrop: In the final chapter.
* TrainingFromHell: Shirou endures some from Myrddin in his mind while he's unconscious.
* {{Tsundere}}: Lampshaded in Rin by Rider.
* UpgradeArtifact: The Noble Phantasms Archer creates can give whoever's wielding them [[InstantExpert the knowledge of how to use them properly, with minimal experience required]] to physically get used to using them.
* VoluntaryShapeshifting: One of the functions of Tarnhelm is to allow the wearer to shapeshift.
* WhatTheHellHero: Rin's reaction to finding out Archer's backup plan is to [[spoiler:use Medusa-Saver to purify the Grail by killing her and letting her cancel out Angra Mainyu]].
* ZettaiRyouiki: Shirou lampshades Rin's zettai ryouiki outfit the first time they meet in-story.
* ZombieApocalypse: The result of Zouken's familiars spreading across Fuyuki through the sewer system.
