History FanFic / FantasyOfUtterRidiculousness

* {{Foreshadowing}}: Throughout the story, a trapped Marissa can be seen struggling to grab her mini-hakkero that's just ''this... much...'' out of reach. No guesses for what happens when she finally reaches it.

* IKnowMortalKombat: Coop learns very quickly the basics of Spell Card duels, mostly because they come off as a game.

* BigDamnHeroes: Marissa is able to accomplish this, although she isn't aware of it.

** ''Z,'' a show discussed later by Coop and Jamie, is meant to be an in-universe take on {{V}}.

** When chewing out Remilia in the final chapter, Patchouli directly quotes MisterT.

** In Chapter 4, Alice is preparing for the unsavory task of dodging attacks from three giant fairies, whose attacks have become massive to match. Cue the sun, literally, as the investigative Patchouli drops her Royal Flare spell card on their heads.

** Coop at one point says [[SledgeHammer "Trust me. I know what I'm doing"]] before attempting to use a sledgehammer against Suika. Patchouli even notes that she doesn't feel that confident in his tactics.

* ArtisticLicenseEngineering: Lampshaded with Megas's Plot Sensitive Button when it reads "Technology does not work this way", just before Coop fires a reverse MacrossMissileMassacre at Suika.

* HilariousInHindsight: After getting trapped inside Megas, Patchouli decides that she's never leaving the Mansion again "for anything short of an earthquake". Fast-forward to the events of ''Scarlet Weather Rhapsody''...

* {{Golem}}: Megas is mistaken as one by the residents of the SDM.

* {{Magitek}}: [[spoiler: In the Alternate Ending, Coop combines Patchouli's "Philosopher's Stone" card with Megas's systems. The resulting multi-element attack KOs Suika and demolishes most of the Scarlet Devil Mansion's library in one go.]]

* IKnowMortalKombat: Coop learns very fast how to use danmaku, mostly because it's a game.

** Part of Flandre's panicked ranting in Chapter Three suggests that she has seen Danny Kaye's ''The Inspector General''.

* CreditsGag: The explanations in the Author's Notes are separated by one-paragraph depictions of events taking place during later visits to Gensokyo.
* DeconstructionCrossover: One common plot in Touhou fanfiction involves one or more characters being dropped into Gensokyo and adjusting to life there, usually because of Yukari (or in this story, because of the Lunarians). The problem here arises when its Coop and the others, with [[HumongousMecha Megas]] in tow, that are warped on in; by the time the battles run their course, Reimu and Yukari are both in agreement that they do ''not'' belong.

* DopeSlap: [[spoiler: In the credits, Koakuma does this to Jamie, so that he stops to hit on Patchouli]].

* IKnowMortalKombat: Coop learns very fast how to use danmaku mostly because it's a game.
* LeaningOnTheFourthWall: The characters notice that there is a music in the background of each battle.
