->''"Bringing your problem to its solution!"''

In the Eight Queens' Lands, a cautious peace between eight rulers has given way to [[EnemyMine a fight with invaders going after all eight]]. Each monarch depends upon her chosen Precure to fight back the Metamasters and their puzzle monsters, the Hanjir. Queen Bianca's Precure, Takaraike Miu (Cure Lock) and her less confident younger sister Takaraike Rei (Cure Cipher), arrive at her palace, ready to present three transformation devices to their tentative ally Queen Shyama. What they find instead is a Metamaster infiltration, and they're sent into a void where they end up separated. Rei falls through a portal and out of the sky into an unfamiliar world...

In the year 2034, the human world is as exciting as ever, but Shinobu Emi feels like there's something missing. She does well in school and she has a lot of admirers, like the sweet and slightly strange Senri Chika, and a fun best friend, Kaji Hideko, who dreams of solving mysteries. Emi, though, doesn't know what to do with her life like everybody else does. But when they see Rei falling from the sky, suddenly there are more important things to worry about.

''[[https://www.fanfiction.net/s/10057836/1/Puzzle-Hunt-Precure Puzzle Hunt Precure]]'' uses a system that twists the WonderTwinPowers of some seasons by not having ''designated'' partners for its Precure, just needing partners ''in general''. It also has a heavy puzzle theme extending to the plot itself.

----
!!'''This fanfic contains examples of:'''
* ActionPrologue: The first half of chapter one has Cure Cipher and Cure Lock fight a Hanjir and get sent into the void.
* AmbiguouslyBrown: Rei and Miu, being from a MagicalLand and thus not corresponding to any particular real-world ethnicity anyway. Averted with Chika, whose ethnicity is spelled out (her mom is Brazilian and she's described as darker-skinned than Emi or Hideko).
* BlowYouAway: Cure Riddle's finishing move.
* BrattyHalfPint: Tetya comes off as this to the other villains (she's the same age as the Cures, but infinitely more annoying).
* ButNotTooForeign: Chika is half Japanese and half Brazilian.
* ByThePowerOfGrayskull: "Link! Precure Solution!"
* CapeSwish: Often and obligatory, since the Metamasters all wear different kinds of capes.
* CompulsorySchoolAge: Averted, as Rei is stated in the character designs to not end up attending Kuromasu.
* CoolBigSis: Miu is much more self-assured as a Precure than Rei is and serves as Rei's encouragement before they're separated.
* DeadFic: Hasn’t been updated since 2014.
* DebutQueue: All five Precure are introduced in the first four episodes.
* DesperatelyLookingForAPurposeInLife: Unlike everyone else around her, Emi hasn't found where she "fits".
* DoesNotLikeSpam: Emi considers egg salad inedible.
* EasingIntoTheAdventure: Rei and Miu start out on a visit to Queen Bianca that quickly goes sour and ends up as the ActionPrologue. Emi and Hideko, however, spend ''their'' portion of episode one mainly going through their everyday lives.
* ElsewhereFic: An OriginalCharacter fanseries.
* GoodColoursEvilColours: Cryptalla has a deep purple aura, and so does all of her magic. The Cures all have pastel themes.
* GovernmentConspiracy: Upon seeing Edel, Hideko briefly wonders if fairies are part of a government cover-up.
* HollywoodAutism: Chika's character in large part calls it out. She has social difficulty (compounded by her shyness as well) and needs the Candy Cluster as aids, she's a teenage Asian lesbian instead of a little white boy, she goes to school and is part of Class 5 (which is equipped to help people with all manner of disabilities) and seems to do well, and her life isn't treated as any less full or worthwhile than anyone else's.
* LoveLetter: Emi gets them regularly and answers every single one.
* MagicalLand: Rei comes from the Eight Queens' Lands.
* MonsterOfTheWeek: They're called Hanjir and they're all literal {{Puzzle Boss}}es.
* MorningRoutine: Emi's is shown in episode one, showing the setting's slight futuristic touches and her hobby of doing the puzzles in the morning paper.
* MyHeroZero: Cure Cipher may be themed after codes, but since "cipher" can also mean "zero", her real name is Rei.
* OminousOperaCape: Cubia's cape is one of these.
* PuzzleBoss: Every single [[MonsterOfTheWeek Hanjir]]. Based on puzzles, they have to be fought only to keep them at bay while the Cures ''solve'' them to defeat them.
* RebelliousPrincess: Hideko initially suspects that Rei is this, or at least a rebellious LonelyRichKid, when the latter appears out of nowhere in a fancy gown covered in dirt and twigs.
* SailorFuku: Kuromasu Middle School's is old-fashioned with a long skirt and slightly poofy sleeves. Emi freely admits it isn't very fashionable.
* SaveBothWorlds: The Metamasters end up attacking the human world, too.
* SeriesMascot: Edel, the girls' de facto fairy, and Nono, who was Rei and Miu's fairy before they were separated.
* SesquipedalianLoquaciousness: Chika uses a lot of big words when she's not stammering and blushing (and often when she is).
* ShrinkingViolet: Chika is very shy, which her robots point out when she's having difficulties.
* StockPuzzle: The series is themed around them. Each MonsterOfTheWeek is one (for example, the first one turns a topiary into a FifteenPuzzle), the Eight Queens' Lands are based on the QueensPuzzle, and characters are themed after them on either side (from [[FallingBlocks Tetya]] to [[RiddleMeThis Cure Riddle]]).
* SuperheroesWearCapes: None of the Precure, but all of the villains.
* ThemeNaming: Everyone and everything is a puzzle.
* TransformationNameAnnouncement: Naturally for all the Cures. "Complete" teams -- first Cipher+Lock and eventually Cipher+Jigsaw+Riddle+Tangram -- also announce that they're [[TitleDrop Puzzle Hunt Precure]].
* TransformationTrinket: The Pre-Cubes, which hold two-piece pins that have to be swapped and mixed with another to use.
* TrappedInAnotherWorld: Rei and Edel are trapped on Earth for the foreseeable future.
* TwentyMinutesIntoTheFuture: Takes place in 2034.
* VerbalTic: Edel's "I think" and Nono's "you see", since, well, they're fairies. Cubia also overuses "well".
* WhiteMaskOfDoom: Cryptalla, leader of the Metamasters, wears one, then wears a cloak over top that obscures half of the mask anyway. The mask also distorts her voice, making her sound unreal.
