Start with ''Manga/RanmaOneHalf''. Have his universe invaded by eldritch abominations, killing the entire cast (and pretty much the entire WORLD) except for Ranma himself, who is rescued at the last minute by an interdimensional agent and set free to wander the planes. Traumatised and alone, he wanders from world to world, never finding anywhere to settle down, and pursued by horrors that could bring an end to creation.

Now take ''Franchise/SailorMoon'', but in a wildly different setting packed full of furries, fairies, vampires, dark goddesses, artifacts from the dawn of time, and bits and pieces of the mythos of a dozen anime series all stitched together into a dark but fascinating whole.

This is the world that wandering-Ranma now finds himself in. Only his dimensional-travel device seems to be malfunctioning, trapping him in this world, and a slew of mysterious deaths is following in his wake...

Not actually a lemon, but certainly a lot HotterAndSexier than the original sources, as you'll see from the tropes.

Can be found [[ here]].

Has nothing to do with the 1970 musical or 1965 broadway production of the same name.

This Fanfiction contains examples of:

* BoardingSchoolOfHorrors: Ami attended one of an unusual sort. They wanted very smart children ''that no one would miss''.
* CatGirl: Genetically engineered by the lost civilisation for use as [[SexSlave sex toys]]. Some of them are specially designed to heal wounds quickly, for customers who like to play rough.
* ClassyCatBurglar: One of [[spoiler: Minako's]] alter egos, who acts JustLikeRobinHood.
* DeadFic: Not even the site it's on has been updated since 2008. And yet the fanbase is still posting on the guestbook and offering prayers for a continuation. (And the guestbook has been broken since 2011 now.)
* DeusSexMachina: Rei and Ami's power combinations can only be controlled through intimate contact.
* EldritchAbomination: Oh yeah.
* EternalSexualFreedom: Anything consenting adults want to do with eachother in any combination is absolutely fine in this world. This flummoxes Ranma to no end.
* EveryoneIsBi: Not quite everybody (Ranma is straight, Rei is a lesbian) but pretty close.
* HornyDevils: Both succubi and incubi. Mostly they stay in their own mystical realm... mostly.
* HostClub: Minako works at one.
* IWasOnlyPretendingToLikeYou: Hotaru's revelation that she had assembled the Sailor Senshi for her own nefarious purposes was what broke up the group the first time around. [[spoiler: Subverted in that it wasn't actually true, Hotaru was just upset at the time and lashing out to drive the others away from her.]]
* KarmicDeath: What Ami did to [[spoiler: the headmaster of her 'school']].
* KinkySpanking: In chapter 3, werecat Rin threatens to put Jupiter over his knee and spank her in front of the whole bar to teach her a lesson.
* LesbianVampire: Wynneth [[spoiler: and, to some extent, her 'daughter' Hotaru.]]
* MysticalWaif: The 'spooky little songbird' who keeps appearing and disappearing.
* ObliviousToLove: Yoshi, or so it seemed.
* {{Polyamory}}: While the characters are not without jealousy issues, sharing does seem to be the norm.
* [[ReallySevenHundredYearsOld Really Seven Thousand Years Old]]: The mysterious little girl [[spoiler: and Gar.]]
* RopeBridge: Lampshaded. As soon as Jupiter catches sight of the rickety rope bridge spanning the chasm, she ''knows'' it's going to come crashing down while the squad is in the middle of crossing it. [[spoiler: And it does.]]
* TitleDrop: In chapter 11, when visiting the Abyss in Aethyr.
* TortureCellar: Finding one of these packed with slaves being beaten makes Ranma lose his cool.
* TransplantedCharacterFic: Ranma is at least supposed to be from something resembling the canon universe originally, but everyone else is far beyond AlternateUniverse.
* TroubledButCute: Yoshi the werewolf, who spent a rough childhood on the streets, was abandoned by his only friend, and was [[spoiler: abused by a sex cult.]] As such characters go, though, he's a pretty nice guy.
* ZeppelinsFromAnotherWorld: An airship crash near the beginning is used to help show that this is a very different setting.
* YouAreTooLate: After correctly seeing through several distractions and fighting their way through a lot of very dangerous resistance, [[spoiler: our heroes arrive just as the Sisterhood begins their ritual, and are powerless to stop it. They have to stand there and watch everyone die.]]
