History YMMV / FateKaleidLinerPrismaIllya

** Chloe. She needs mana to live and isn't fussed about how she gets it, serving as a constant banging reminder that SexMagic exists even in a parody of the {{Franchise/Nasuverse}}... which wouldn't be so bad if she weren't ''ten years old'', making her the walking incarnation of FilleFatale. While she isn't the only case of questionable lewdness in the {{Franchise/Nasuverse}} or even ''PRISMA☆ILLYA'' itself, she's definitely the worst offender, and her antics have gotten the series an unfortunate reputation as "that lolicon fanservice show" when they were meant to be PlayedForLaughs.

All instances are PlayedForLaughs of course, but only half of the fanbase sees it as such while the other half thinks it's pushing the envelope too hard.

* TakeThatScrappy: In the third arc: for those who didn't like [[spoiler:Sakura's]] actions in the Heaven's Feel route of ''stay Night'', Miyu's flashback nips that in the bud by [[spoiler:killing her Miyuverse counterpart off and using Miyu as a more innocent Sakura analogue.]]

** The FoeYay between Rin and Luvia borders on BelligerentSexualTension. This is especially obvious in the manga, and in places like the special where Rin is made to be Luvia's {{Meido}}. Also, [[http://st.cdjapan.co.jp/pictures/l/03/30/LACM-14288.jpg?v=1 official art like this.]]

* FoeYay: The pair of [[spoiler:Miyu's Shirou]] and [[spoiler:Angelica]] has become popular during their fight. The former has some [[ShippingGoggles ambiguously flirty]] dialogue along with directly calling her ''cute''. The latter seems to be continually trying to talk him down from fighting and seemed hesitant to kill him.
** [[spoiler: Even more so now that Angelica is revealed to be somewhat similar to the Shirou from Miyu's world. Some are even finding similarity between them and F/Z Kiritsugu and Irisviel.]]
** [[spoiler: As of Chapter 48 of ''[=3rei=]'', it's become so blatant on Shirou's part that EveryoneCanSeeIt.]]

--> '''Sakura''': By the way, the movie is supposedly about a MagicalGirl... but where exactly ''was'' the Magical Girl? I feel sorry for the person whose name is in the title.

* SophomoreSlump: 2wei is seen as the weakest in the anime adaptation, due to ramping up the fanservice (which, as seen below, is unnerving at best) and having the weakest plot of all three arcs that were adapted.
* {{Squick}}: The fact that Illya and Miyu are 10 years old in this continuity rather than being OlderThanTheyLook -- not to mention [[LoveableSexManiac Chloe]] -- and are regularly shown in some rather adult situations has grossed out a lot of western viewers and reviewers, and even gotten the show banned as child porn in some countries.

** Still others are [[DarknessInducedAudienceApathy simply tired]] of ''3rei's'' [[ToneShift considerably more serious tone]] regardless of the characters involved, which the Miyu arc has only [[DarkerAndEdgier exacerbated further]]. Previously, ''3rei'' had paced its more serious drama and action with a plentiful sprinkling of comedy and Fanservice in between, even showing [[spoiler:the Ainsworths']] ([[FauxAffablyEvil Faux]]) AffablyEvil side, and if pacing didn't allow for such breaks there were often [[BreatherEpisode purely comedic side-chapters]] to give the reader a break. In contrast, this story has seen CerebusSyndrome in full effect, being a nonstop TraumaCongaLine for [[spoiler:Shirou]] approaching levels of bleakness that wouldn't be out of place in ''[[VisualNovel/FateStayNight Heaven's Feel]]'' or ''LightNovel/FateZero'', and [[ShooOutTheClowns without a single side chapter and hardly any appearances by the regular cast to break the tension]]. You'd find it hard to believe the series started as a lighthearted love letter to the MagicalGirl genre. Thankfully, the flashback doesn't last ''too'' long, and [[spoiler:Shirou]] even [[LampshadeHanging lampshaded]] how long it was. If that wasn't enough, the 5 minute short released with the ''Oath Under Snow'' Blu-Ray disc throws in even more lampshading.

** Chloe. She needs mana to live and isn't fussed about how she gets it, serving as a constant banging reminder that SexMagic exists even in a parody of the Franchise/Nasuverse... which wouldn't be so bad if she weren't ''ten years old'', making her the walking incarnation of FilleFatale. All instances are PlayedForLaughs of course, but only half of the fanbase sees it as such while the other half thinks it's pushing the envelope too hard.

* BaseBreakingCharacter: [[spoiler:Miyu's brother]]. While general opinion is positive compared to [[spoiler: his counterparts in Illya's world and the original ''stay Night'' visual novel]], you'll find some folks saying he [[spoiler: merely upgraded to StockLightNovelHero]] given his circumstances.

** [[spoiler:Miyu's brother]] being thrown in an AlternateUniverse right after ''Oath Under the Snow''. Usually he ends up in the world of ''VisualNovel/FateStayNight'', but it's not unheard of to use this setup for crossovers.

* FandomSpecificPlot: There's a surprisingly high amount of fandom ideas where [[Videogame/FateGrandOrder the Fujimarus]] get similar powers to Illya and start collecting their own class cards. Strangely, it's ''male'' Ritsuka that is treated as the counterpart in these plots, though just as often they'll use Mash as the Illya stand-in.

* SomeAnvilsNeedToBeDropped: The third episode of season 3 had Mimi becoming a YaoiFangirl, which weirds Illya out. Suzuka's sister intervenes and tests Illya by saying that if they can't reach an understanding, they might as well stop being friends. A guilty-feeling Illya realizes that while she may not be into yaoi herself, that's no reason to break a friendship. It's especially poignant given that the show has a lot of older male Fate fans that are into yuri themselves, and see that aspect as an appeal of this show, but are otherwise aversive to yaoi.

* IKnewIt: Many readers familiar with the {{Franchise/Nasuverse}} at large had slated Tanaka as having something to do with [[spoiler:the Counter Force within minutes of Illya meeting her. The twist that shocked them was that she was born of ''Gaia''[[labelnote:*]]the planet's will to survive[[/labelnote]] rather than Alaya[[labelnote:*]]humanity's will to avoid extinction[[/labelnote]], let alone actually '''[[AnthromorphicPersonification being Gaia's Counter Force itself]]'''. Gaia is remembered as an [[GaiasVengeance antagonistic force]] in ''Literature/AngelNotes'', but in ''PRISMA☆ILLYA'', Illya's unwavering desire to save both the world and humanity has [[AdaptationalHeroism placed Gaia's avatar firmly on the heroes' side]].]]

* AdaptationDisplacement: Rare example of this happening on a character scale: the ''Prisma'' version of Illya has gotten popular enough to lock horns with the ''stay Night'' version.

* LikeYouWouldReallyDoIt: The death of [[spoiler:Chloe, one of Illya's co-heroines,]] was foreshadowed all over the place, but was handled believably and even included a DyingMomentOfAwesome. That's not this trope. What ''is'' this trope is the events that followed in the ''very next chapter'', turning it into a NegatedMomentOfAwesome resulting in the SurprisinglySuddenDeath of [[spoiler:Illya's ''other'' co-heroine]] and a very abrupt [[spoiler:ApocalypseWow]]. It quickly became clear that much of this wouldn't stick, with even Hiroyama himself [[LampshadeHanging hanging an obvious lampshade]] in an author's note. [[spoiler:Sure enough, SetRightWhatOnceWentWrong was on the table a couple of chapters later.]]

** From ''3rei'', [[spoiler:Tanaka]] is widely hated for being as stupid as one could possibly get without forgetting how to breathe. It hurts that [[spoiler:for her desire to get rid of the Ainsworths, ''which is the only defining characteristic of her personality'', she does almost nothing during the FinalBattle, only giving Illya a long distance power-up]].
* SomeAnvilsNeedToBeDropped: The third episode of season 3 had Mimi becoming a YaoiFangirl, which weirds Ilya out. Suzuka's sister intervenes and tests Ilya by saying that if they can't reach an understanding, they might as well stop being friends. A guilty-feeling Ilya realizes that while she may not be into yaoi herself, that's no reason to break a friendship. It's especially poignant given that the show has a lot of older male Fate fans that are into yuri themselves, and see that aspect as an appeal of this show, but are otherwise aversive to yaoi.

** Illya's maid {{Fetish}} results in her ''mounting'' Miyu (''twice!'') before she can compose herself. Miyu didn't mind.

** [[spoiler:Chloe]] in general with both Miyu. In 2wei she managed to make the former unconscious with a French kiss.

The readers were only too quick to realize that most of this, if not all of it, was not going to stick, with even Hiroyama himself [[LampshadeHanging hanging an obvious lampshade]] in an author's note.

** Shirou is already a major BaseBreakingCharacter as a whole in ''VisualNovel/FateStayNight'' for BrokenBase reasons, but a lot of fans consider this version of him to be even worse than his DEEN and Ufotable versions, mainly because he's bland and completely superfluous, and don't find the RunningGag of [[ChickMagnet women falling for him]] to be that funny. In addition, there's DieForOurShip at play, as most of the {{Yuri Fan}}s in the fanbase will raise their hackles at any ShipTease he gets with girls, as he's a possible canon threat to ''either side'' of ''both'' [[FanPreferredCouple Fan-Preferred Couples]] Illya/Miyu and Rin/Luvia. [[spoiler:The Shirou from Miyu's world, however, is a MemeticBadass]].

*** [[spoiler: Then comes Chapter 8 of 3rei where the BigDamnKiss happened between Chloe and Illya]].
