[[quoteright:230:http://static.tvtropes.org/pmwiki/pub/images/Fate_Hollow_Ataraxia_cover_7391.png]]

''Fate/hollow ataraxia'' is the fandisc pseudo-sequel to ''VisualNovel/FateStayNight'' and one of numerous works that take place in the Franchise/{{Nasuverse}}. It is based on an unusual version of events: The Grail War has ended, Kotomine and Gilgamesh have been defeated and all is well. Only... all the Servants are still around and everyone seems to be alive. Well, okay, reasonable enough if you can't follow just one ending. But it's not that simple: Apparently thanks to Tohsaka's attempts to create a magical item based on dimensional hopping, all the different continuities have been mingled including ones we never saw. So what really happened and what's going on?

And that's not all there is to it. While Shirou and the Servants and Masters are leading their oddly domestic lives together, something darker is going on. Strange beasts are spotted and an unfamiliar magus appears to have restarted the Heavens Feel. That said, none of the Servants seem to actually care since they've settled into their new lives. Yet while this is going on, time seems to be looping in an odd manner, lasting four days before the world resets back to the first day with no apparent sign of any continuity between cycles.

On top of all that, no one seems to have informed Bazett Fraga [=McRemitz=] that the Fifth Grail War ended six months ago. She's not really sure why, but rather than the Servant she intended to summon she seems to have ended up with someone... darker. Meet the eighth Servant whose identity was only hinted at in the [[VisualNovel/FateStayNight first installment]]: Avenger, the Spirit of Vengeance. Avenger seems completely psychopathic but utterly weak... but is that really all there is to it?

After years in DevelopmentHell, a finalized and complete FanTranslation was finally released in November 2014. Please do not add details that relate to ''VisualNovel/FateStayNight'' and reserve this page for those dealing only with this story.

An {{Updated Rerelease}} was also released in Japan in November 2014 for the PS Vita, with anime cutscenes done by ufotable and full voice acting.

----
!! This story provides examples of:

* OneHundredPercentCompletion: There's an actual meter for it.
%%* AllJustADream - OrWasItADream
* AlternateContinuity: Essentially all routes and [[MultipleEndings endings]] of ''VisualNovel/FateStayNight'' have been mixed together. So for the final battle Saber beat Gilgamesh and Shirou killed Kotomine. However, Rin's command seal was the one used to destroy the Grail and Saber is still around. Just like HF, Sakura's free from Zouken's control, the great Second Sorcery was projected in Shirou's shed, among others.
* AndNowForSomeoneCompletelyDifferent: Saber gets to narrate for a short period. It is hilarious.
* ArtificialLimbs: [[spoiler:Kirei cut off Bazett's arm during the Fifth Grail War. At the end of Ataraxia, Bazett replaces it with an artifical arm]].
* ArtShift: A movie seen in ''hollow ataraxia'' is presented with live action pictures of different types of dolls instead of the usual art style. Doubles as a CrowningMomentOfFunny.
* AuthorTract: During the opening montage, Avenger starts ranting about how the world is dying and how much better things were in the good ol' days. Then again, this is a physical fact of the setting that [[TimeAbyss Avenger]] would obviously be aware of, and [[OlderIsBetter this ideology]] isn't particularly pushed by Nasu in this work or any other, so ...
* BackToBackBadasses:
** [[spoiler:Assassin and Souichirou]] in the final battle and the opening sequence by Ufotable.
** Both a group of the Association's Enforcers and the Church's Executors were sent to stop the same magus that was using corpses in an attempt to revive the soul. All but one of each group were wiped out and they decided to [[EnemyMine cooperate in order to survive despite the fact each of their organizations is the other's ideological antithesis]]. [[spoiler:This is how Bazett and Kirei Kotomine met.]]
* BadDate: [[TakeOurWordForIt While we don't get to see it first hand]], Shirou and Rin's first real date after the Holy Grail War was a shining example of Murphy's Law. While their dinner at a fancy restaurant went off without a hitch, their plans for a redo of their less-than-ideal [[TheirFirstTime first time]] during the ''Unlimited Blade Works'' route certainly didn't. They reserved a luxurious room in a Western-styled hotel, but Rin's [[HopelessWithTech Hopelessness With Tech]] kicked in and she messed up the AC setting ''and'' [[EpicFail somehow destroyed the remote control in the process]], leaving the couple stuck in a too-cold room for any kind of romantic mood. They persisted, but then Shirou accidentally tore open a small scented pouch that Rin sewn to her clothes[[labelnote:Long story short]]she has to take medicine for her Magic Crest that makes her exude a distinctive herbal smell she's self-conscious about and she hides it with perfume[[/labelnote]], releasing the chemicals to the air and saturating the room with the odors of the undiluted compounds. [[spoiler:Amazingly, they still managed to get it on that night -- no survivor of the Holy Grail War is a quitter, you see.]]
* BleachedUnderpants: Like the ''[[UpdatedRerelease Realta Nua]]'' port of ''VisualNovel/FateStayNight'', ''Hollow Ataraxia's'' Vita port removes all the naughty and erotic bits from the original PC port and either replaces them with much tamer, non-sexual alternate scenes, or heavily tones them down. [[spoiler:Caren's rape at the hands of Avenger is replaced with a different scene that plays out similarly to Realta Nua's version of Sakura's love scenes from Heaven's Feel.]]
* BodyHorror: Spikes erupt from Caren Ortensia's skin in the presence of evil.
* BreadEggsMilkSquick: Sakura's book collection is about what you'd expect it to be- home economics, stress relief, cookbooks, and familicide.
* BridalCarry:
** Shirou does this twice for Tohsaka. The first time at school after she collapsed because her Magic Crest started to act up and he carried to the infirmary so she could rest. This gathered something of an audience and some gossip about them.
** The second time happened at her place the next day, after she lost consciousness during a phone conversation with Shirou as she condition worsened. He panicked at the idea that an enemy could have attacked her while alone just like late in the ''Fate'' route of the original visual novel. He ran to her house, finding her half-conscious on her sofa and he ended up carrying her to the bedroom. The newlywed imagery didn't go unmentioned.
* BroadStrokes: Enough of the ''VisualNovel/FateStayNight'' continuity is fleshed out that you realize that one single story couldn't possibly hold it at all.
* TheCameo: [[VisualNovel/{{Tsukihime}} Satsuki, Len, Kohaku and Hisui]] make an appearance when Shirou and Rider go to see ''[[ShowWithinAShow Tiger - The Movie]].''
* CharacterizationMarchesOn: Actually less than one might think - this is the game that helped flesh out all the "Stay Night Seven" after ''F/SN'' itself, and even solidified Angra's characterization for later appearances - but there's still a few odd examples that will stick out to newer fans in a post-''VideoGame/FateGrandOrder'' world.
** The ''biggest'' are Euryale & Stheno. Here, they're almost completely ''interchangeable'', they both share the same outfit and nearly (but not ''quite'') the same sprite and it's very difficult at times to differentiate one from the other; this is where, and why, they picked up the gimmick of referring to each other as "me". ''Grand Order'' would go on to differentiate their personalities and appearances significantly (Stheno being calm & collected and Euryale being energetic & flirty; Stheno's is closer to the personality both have in ''F/HA''), and even give the two different classes (straight down to Euryale getting mixed up a bit with Eros and gaining Archer abilities).
** Rider gets a little bit of it - ''HA'' rather implies, logically, that most of her actual career as guardian of the Shapeless Isle was in the form we know Rider in today, that when she was a "child" she looked much more like her sisters ([[AllThereInTheManual character material guides]] would provide an illustration of this), and that when she [[spoiler:went "full Gorgon" and murdered her sisters, she was kind of a pillar of snakes]]. ''Grand Order'' would go on to expand on this, both showing how "Rider" was more like a Lancer early in her career, how her outfit and appearance in that period was ''much'' different than that of her sisters, [[spoiler:and showing that her Gorgon form was more complicated than just the snake pillar we briefly see, though that is part of Avenger Gorgon's Noble Phantasm]].
** We very briefly get a glimpse of [[spoiler:Perseus]] at one point during Rider's flashbacks. [[spoiler:The Perseus Rider that's been teased in ''Anime/FatePrototype'' material looks ''significantly'' different to the one in ''F/HA'', though his appearances have been brief enough so far that it might just be him not having time to showcase his armor and whatnot.]]
* ChekhovsGunman: Avenger and Angra Manyu were both mentioned in passing in ''VisualNovel/FateStayNight'' but the concept of the anti-hero[[note]]Which here means the complete opposite of a hero rather than a hero with a ShootTheDog mentality[[/note]] was never explored apart from some implications that both Rider and Caster fit into that class. Though Avenger denies being ''the'' Angra Manyu.
* ClosetShuffle:
** Saber asks Shirou how a swimsuit set looks on her, but [[PleasePutSomeClothesOn he's too embarrassed to even look at her and all but begs her]] to summon her InstantArmor. Then they hear Taiga approaching the room and he freaks out at the prospect of their UnwittingMuggleFriend seeing Saber in her magical BattleBallgown and pushes the latter into the closet. For a moment it seems like his fast-thinking is working until Taiga points to Saber's usual clothes neatly folded into a pile ([[BrickJoke from when she tried her swimsuit on]]) and [[NotWhatItLooksLike gets the idea that something]] [[InterruptedIntimacy a lot less wholesome was just happening]]. Needless to say, HilarityEnsues.
** In the Eclipse scene, Shirou and Sakura remember one time they were, ahem, ''together'' in his bedroom when Rider suddenly came in at midnight with no warning. Sakura reacted fast enough to hide in his closet before she noticed, but yeah… awkward.
* ContinuitySnarl: If you keep track of everything that is mentioned in the story, you'll note that Shirou has to remember an impossibly complicated and possibly contradictory series of events. For example, he remembers Tohsaka beating Caster in close range combat in the church like in ''Unlimited Blade Works'' but he also remembers her being impaled by Gilgamesh outside his house as she was in ''Fate''. Thankfully, this is the [[{{multiverse}} Nasuverse]], so all routes are canon (even ones that were never shown, like Illya's route). [[spoiler:Though ultimately this is also a major hint that something very weird is going on.]]
* CoolCar: Illya owns a Mercedes Benz, 300SL Coupe, with a top speed of over 270 KPH. (Possibly a mistranslation?) She does, in fact, drive it around the Fuyuki area (after all, [[spoiler:she ''is'' eighteen]]).
* CuttingOffTheBranches: Ataraxia ignores the sometimes large contradictions between routes and throws almost all of it in.
* DeathIsCheap: Thanks to the time loop. The first couple times you go to the bridge, Shirou gets sniped. Bazett is also killed multiple times in fights against Servants and uses the resurrection to her advantage.
* DemotedToExtra: While some Servants and Masters get larger roles than they had previously such as Lancer, Kuzuki or Caster, others don't fare so well. Here's to you, Shinji, who broke the fourth wall to state it outright.
* TheDevil: Subverted. Avenger states that his identity is that of Angra Manyu, but that he is not the demon god of legend. Rather, it's just a title that was given to him when his old name was taken away. [[LemonyNarrator He says he would rather be the god of something more mundane like pots or something since he isn't that special]].
* DoorStopper:
** A OneHundredPercentCompletion run consists in reading whopping ''486,000''' words[[note]]this is calculated by running UsefulNotes/{{Unix}}'s standard word counter program (wc) on the scenes' English script after removing comments and instructions meant for the machine from the [=Kirikiri2=] code[[/note]]. For reference, the trilogy of ''Literature/TheLordOfTheRings'' is around 455,000 words long.
** For an in-game example, the tree parts of the ''Himuro The Love Detective'' side-story are 24,000 words long total, which is well above the average of 2,000 words per scene.
* DysfunctionJunction: This has actually been glossed over to a large extent. For example, Illya has ''mostly'' relaxed, Shinji has stopped being quite so horrible and Sakura has grown a lot bolder, meaning while all the bad stuff is noted as still having occurred, [[CharacterDevelopment people have mostly moved on.]]
* EmpathicWeapon: Zelretch's Kaleidostick. An incredibly powerful magical device capable of channeling enormous amounts of {{mana}} and giving its wielder powers and knowledge pulled from alternate realities, [[spoiler:with the drawback being that it derives considerable joy from humiliating said wielder and forcing them into ridiculous MagicalGirl costumes]].
* FacialDialogue: Shirou and Saber are quite a tight-knit team even in MundaneMadeAwesome situations.
-->'''Shirou:''' ''[narrating]'' Saber's eyes and mine silently meet.\\
'''Saber:''' —I shall lure Rin away from here.\\
'''Shirou:''' —Ah, yeah, please do… Alright, leave the rest to me.\\
'''Saber:''' —Understood. So please make plenty of stew.\\
'''Shirou:''' —Roger. I'll take great pains to make at least 20% more than we'd planned to.\\
'''Shirou:''' ''[narrating]'' Eye contact, completed. Transmission, over and out.
* {{Familiar}}: All the Servants are a type of Familiar. Shirou wonders why Lancer is still around since his Master died. As established in ''[[VisualNovel/{{Tsukihime}} Kagetsu Tohya]]'' only the most powerful familiars can stay alive even a little while after their master dies. [[spoiler:Turns out he and Kid Gilgamesh have a new one]].
* FanDisservice: Caren's eroscene. [[spoiler:Angra Mainyu, in the form of Shirou, suddenly forces himself on her and rapes her, out of a combination of lust and raw sadism. The act causes her ''immeasurable'' pain because of the way her body reacts to demons, and she spends the entire scene trying to keep her body from violently erupting and killing him, with parts of her body being torn apart internally as she does so. She actually starts to enjoy it towards the end, but by then Angra Mainyu has ''reverted to his black beast form!'']]
* {{Filler}}: A large amount of scenes have little to do with the main plot. For example, scenes with Rider flirting with Shirou, developing the track girls from the school or slice of life with Sakura. The story takes awhile to kick into gear on the Shirou side of the story with the actual plot events being tracked ingame. This is mostly because the game is a fandisc mainly devoted to harem antics with Shirou and many a FandomNod.
* FinalBattle: [[spoiler:The Masters and Servants versus the Avenger copies.]]
* FissionMailed: Sneaking into Sakura's room with Shinji to look at her diary results in this.
* FoodPorn: Ooh yes. When three of the main characters are on the rank of SupremeChef, this is inevitable.
* ForgotAboutHisPowers: The reason Shirou [[spoiler:gets sniped by Archer]] the first few times he tries to cross the bridge at night? He simply [[OutOfCharacterAlert forgot to practice his projection magic.]]
* FountainOfYouth: Gilgamesh did this with a youth potion because, apparently, "this whole mess is stupid, screw you all". All the more hilarious, considering that he's been an EvilOverlord (in the past), not to mention a [[KickTheDog dog-kicking]] BigBad who wanted to unleash a terrible curse on humanity because only those who could survive it were worthy of being ruled over; when he reverts, he turns into a cute little kid that everyone loves.
* FriendlyEnemy: Lancer sees no reason not to get along well with his enemies, but on the flipside is that if you're an enemy then you are perfectly fair game to be killed no matter how much he may like you.
* FutureMeScaresMe: Kid!Gilgamesh disapproves of his future self's attitude about leadership.
-->'''Young Gil:''' The only type of person one can rule over is one who wishes to be ruled over. Unfortunately, it seems that I forget this once I grow older. If I had a choice, I would've liked to become a good leader. Why is it that other rulers attempt to rule through fear when the correct path is so simply trod?
* {{Gainaxing}}:
** {{Discussed|Trope}}. When Shirou and Sakura discuss swimming styles at the pool, she mentions that she's not good at the backstroke. He was a brief ImagineSpot about how it would be like for someone as busty as Sakura to swim like that with the small bikini she was wearing at the time and almost gives himself a {{Nosebleed}}.
** PlayedStraight during the rehearsal of the SchoolPlay the Archery Club intended to perform for the [[SchoolFestival Cultural Festival]]. Sakura gets a part as the "rabbit", which involves a small sing and dance number with lots of hopping, something Makidera loudly complains about due to this trope.
--->'''Kaede:''' Are you happy swaying like that!? Is this reverse sexual harassment!?\\
'''Sakura:''' N-No, it's not "swaying," it's "hopping", [[VerbalTic byoing]].
* GameplayAndStoryIntegration: Unlike the others, there are two different ways to {{unlock|ableContent}} Rider's Eclipse scene: Either unlocking first a series of SliceOfLife scenes until reaching the one where she and Shirou have a date at the shopping mall, or finding and reading each scene exploring her past and her nature as a monster. [[FridgeBrilliance This makes a lot of sense]] when you read the extended version of the scene "Monster" titled simply "Not" and realize that the point the novel was trying to make is that the ''two'' of them are Rider's true natures existing right next the other: the socially awkward yet caring protector, and the homicidal monster that takes delight in its killing.
* GoodPeopleHaveGoodSex: Shirou and Rin's adorable ''"cat-pajamas"'' love-scene is one of the most {{Heartwarming Moments}} in the game.
* {{Gotterdammerung}}: This game gives us the first true taste of "Modern Magecraft vs. [[OlderIsBetter the Age of Gods]]". Though Caster notes that the likes of Sakura and Rin have some absolutely amazing potential and in her age it seems there were no True Magics like what Zeltretch can do.
* TheGreatestStoryNeverTold: Played for laughs- Shinji and Shirou have a card battle to decide the fate of the world. Overlaps with UltimateShowdownOfUltimateDestiny and BigLippedAlligatorMoment.
* GroundhogDayLoop: Surprisingly, apart from the gameplay functions of the four days continuously looping for Shirou's half of narration Avenger admits outright after the first time he and Bazett are killed that the four days will keep looping even if they're killed.
* HandWave: There's a scene aptly named "Memories" where Illya tells Shirou about Saber, Kiritsugu and Irisviel about halfway through the game that devotes itself to tying up the canon neatly, particularly the parts that made no sense such as Saber and Kiritsugu never talking, Saber not recognizing Illya despite having met her and Irisviel not only going unmentioned in the original game but also the implication that she wasn't even in town then. Some of the explanations are better than others. This would serve as the basis for what would become ''LightNovel/FateZero''.
* HyperspaceArsenal
** Servants can have their Noble Phantasm coming out of thin air. {{Justified|Trope}} by the Holy Grail War system. Lancer pulls out Gae Bolg at one point to show to Ayako. And also chop flowers for a get well bouquet.
** Gilgamesh, who can literally pull thousands of original Noble Phantasms out of thin air thanks to his Gate of Babylon, takes this one step further. While he technically owns every legendary weapon, this is one of his few genuine Noble Phantasms and is the key to his treasury, allowing him to remove weapons, wealth, wine and divinity sealing chains.
* InnocentInaccurate: Shirou remembers seeing Kiritsugu off at Fuyuki's harbor due to his frequent travels overseas. He never thought much of it until recently when he connected the dots and figured out that his father was most likely illegally leaving and entering the country on a regular basis. Given that his old man took down an airliner inbound to New York with a surface-to-air guided missile in ''LightNovel/FateZero'', it isn't really too surprising for him to be extra careful of airport security.
* JackassGenie:
** [[spoiler:The Holy Grail, due to Angra Manyu's influence, will twist any wish made to it in a way that will kill or hurt as many humans as possible. The Servant Angra Manyu himself doesn't qualify: his will to realise truly one wish is why Bazett survives.]]
** [[spoiler:The Kaleidostick. An 11-year-old Rin wanted to be a better singer and used the Mystic Code to temporarily [[InstantExpert give herself the skills]] of a "Tohsaka Rin who's good at singing" from a parallel world. Ruby fulfilled this wish by granting Rin with the skills and ''personality'' of an AlternateSelf of hers who happened to be a super GenkiGirl IdolSinger. While in her "Prism Trance", Rin hijacked a live performance in a nearby park and sung for the surprised audience "like an idol from the eighties". Rin is ''very'' bitter about this and the fact she had to reset her network of friends in middle school because no kid had the guts to speak to her afterwards.]]
* KungFuWizard: Tohsaka beating up Caster in hand to hand combat is mentioned and then averted for Caster herself, who does not have super strength. Though she's probably still fairly strong considering all the stuff she was carrying.
* LighterAndSofter: The story has its dark moments and is still a Franchise/{{Nasuverse}} work, but is more character-driven, doesn't always take itself seriously and uses and abuses the {{trope}} DeathIsCheap.
* LimitedWardrobe: Almost everyone has, at most, two sets of clothes (typically school, armor, armor/casual, or school uniform/casual, or in Illya's case, cold-weather/normal). Other non-standard outfits are Dark Sakura, Illya's Dress of Heaven, Rin's bedclothes, and the occasional birthday suit.
%%* LoadsAndLoadsOfCharacters
* LuminescentBlush: Among others, the three main heroines, Saber, Rin and Sakura, are prone to this.
* MagicWand: The Kaleidostick
* MiniGame: There are two as UnlockableContent. [[spoiler:The Hanafuda card game and the "Operation: Illya's Castle."]]
* MomentKiller:
** Sakura does it all the time for Rider, killing many a moment with Shirou.
** All of the heroines have somewhat of a jealous streak, so many a moment is killed by all of them. Like when [[spoiler:Saber and Rider [[DatePeepers spied on]] Sakura's date with Shirou at the pool, and when Rider outright crashed on Rin's.]]
* MoodWhiplash:
** The appearances of Rider's sisters in her backstory, where they are initially shown bullying her terribly in scenes that are played for laughs, but then comes the harsh reminder that Medusa turned into a monster and [[TheDogBitesBack devoured both of them]]. Her memories of being bullied by them are [[TraumaCongaLine the fondest ones she has]].
** A more light-hearted example from Rider's backstory is a grim scene of her stalking through her temple, examining the statues left by the warriors she's turned to stone over the years. She drives her chain-dagger weapon into two of them... [[MundaneUtility then uses the stretched-out chain as a clothesline for hanging laundry on]].
** An In-universe example occurs when the girls are swapping stories about growing up with their own elder siblings. Saber tells a fairly heartwarming story about her foster-brother Sir Kay. [[BrokenBird Sakura]] [[BigBrotherBully goes]] [[RapeAsBackstory next]]. We don't actually hear her story, but it leaves everyone feeling "numb and lifeless."
** Shirou feels some apprehension about visiting the basement at Tohsaka's place, wondering what kind of magical rituals have took place in there. When he actually goes in, he instead finds a bunch of athletic equipment, like dumbbells, a punching bag and a [[https://en.wikipedia.org/wiki/Mu_ren_zhuang kung-fu wooden dummy.]]
* MundaneUtility:
** Lancer picking flowers and showing off for girls with Gae Bolg, an ImagineSpot of Rider petrifying policeman who are after her, Saber unleashing the Barrier of the Wind King when Shirou teases her about her stuffed lion and more.
** Caster has her clothes enchanted with water/stain/grease-repelling magic and she also wield an antibacterial protective shield. You could say that cooking for her husband is SeriousBusiness for Caster.
** Archer can use his Projection magic to imitate every legendary, immensely powerful weapon he's ever seen. He can also use it to make a modern, top-of-the-line fishing rod.
** When Rider's RapunzelHair becomes too disheveled, she can fix it by shifting into Spirit Form and back, which resets it to its default form without having to go through all the hassle of combing it. Somewhat {{Subverted|Trope}} in that she doesn't resort to this much because she doesn't want to be a burden to Sakura who provides her with magical energy for something trivial like that.
** Bazette using Fragarach to win a game of Rock, Paper, Scissors.
* MutualEnvy: Saber and Rider admit as much when they see each other in their swimsuits at the pool. Saber admires Rider's perfect mature beauty, which makes a lot of sense once you consider that even in life [[NeverGrewUp she was stuck at an adolescent age]]. Rider's InternalizedCategorism about what's cute and what isn't is such that she [[IAmNotPretty truly doesn't consider herself beautiful]] and has something of a ramped-up HugeSchoolgirl complex, instead admiring petite and youthful beauties like Saber.
* MyFutureSelfAndMe: Trapped inside a pocket dimension, Rin and Shirou try phoning for help- and end up talking to alternate versions of people they know, including [[spoiler:Rin's future self, who is madly, hopelessly in love with Shirou. Present Shirou wonders what he could have done to make her so lovey-dovey, while Present Rin is seemingly astounded that anyone would fall for him in the first place]]. Overlaps with OtherMeAnnoysMe, although hilariously [[spoiler:Rin doesn't recognise her own voice and assumes her future self is just "some strange woman" Shirou is going to meet]].
* MythologyGag:
** Sakura gives an almost perfect description of [[VisualNovel/{{Tsukihime}} Akiha]] and even says the person she's talking about is named Tohno. She's actually talking about Tohsaka, but it's amusing nonetheless. There's also a scene called Kagetsu Tohya, though it has little relation to that story. Neko-Arc is also referenced as the title of a completely nonsensical movie that is currently showing.
** Saber likes takoyaki. Or at least she does until she finds out they're made of octopi [[LightNovel/FateZero due to tentacle-related reasons]].
* NoodleIncident:
** The scene where Shirou and Rin get trapped in Zelretch's chest and try to cal for help by phone provides several when they end up contacting people from parallel worlds. Like whatever Shirou's AlternateSelf did to become a SickeninglySweethearts with his version of Rin, or how another ended up working with Luvia, or whatever happened to make that version of her and Rin jump off the Tower of London together while on the run from the Clock Tower.
** In a rare not-totally-hostile moment, Archer advices Shirou to avoid sightseeing with "you-know-who" in bridges "that might have songs written about them" and that "it's be to [Shirou's] benefit to train [himself] into a really good swimmer". The implication is that something happened in Archer's past that could still happen in Shirou's future involving Rin, London Bridge and having to swim in the cold waters of the River Thames in winter. If "Tower of London" and "London Bridge" means "[[https://en.wikipedia.org/wiki/Tower_Bridge Tower Bridge]]" in this context, it's possible that this NoodleIncident is the same than the one above with Luvia and Rin.
* NoOntologicalInertia: All the Servants being able to stick around is odd, but has some precedent with the ''Unlimited Blade Works'' good end and ''Heavens Feel'' true end, but Shirou wonders why Lancer is still around after the death of Kotomine.
* NoRomanticResolution: In this continuity Shirou does not seem to have settled down with anyone in particular, though sex scenes are still implied to have taken place.
* NotHimself: Many of the characters are nothing like they were in ''VisualNovel/FateStayNight'', which [[spoiler:is actually an early clue that something's wrong with this reality besides the whole GroundhogDayLoop thing]].
* NotIfTheyEnjoyedItRationalization: [[spoiler:Avenger rapes Caren, but this is not addressed much by either party, and they both seem to come out better people for it. Caren 'begins to consent' halfway through, and doesn't seem particularly upset about the encounter afterward. They even have a romantic and touching moment later on...]]
* OlderThanTheyLook: Saber, who is said to look a couple of years younger than Shirou, but is actually around seven years his senior due to the age-stopping effect of Avalon when possessed by its rightful owner. Gilgamesh also appears in child form and Illya is a homunculus and thus has what has been called 'unusual growth patterns' and thus looks around ten.
* OptionalSexualEncounter: The PC version of the visual novel includes them as UnlockableContent, one for each of the original three main heroines [[spoiler:and Rider]] as a reward for unlocking and completing specific scenes.
* OverreactingAirportSecurity: The reason why Tohsaka refused to take her BiggerOnTheInside magic chest to London despite how convenient it would be.
* PowerPerversionPotential:
** Rin resorts to the same gravity-dampening spell she used to jump off a rooftop and over the security fence in ''VisualNovel/FateStayNight'' (and [[ContinuityNod her father before her]] used to gently descend to his battle with Berserker's Master in ''LightNovel/FateZero'') during her OptionalSexualEncounter with Shirou. Her motive to cast it on herself is surprisingly unperverted and pragmatic[[labelnote:if you want details…]]In a {{Subversion}} of IdealizedSex, due to her inexperience Rin simply couldn't spare the concentration to not put too much weight on her elbow and Shirou's stomach while blowing him in a sixty-nine position.[[/labelnote]].
** Illya tries to use her HypnoticEyes to make Shirou agree to "become hers." {{Subverted|Trope}} when he remembers the time he almost fell for it in the ''Fate'' route and then he uses her words against her by asking her "if she would become his if she likes him", which leaves her a blushing mess.
** As in the ''Heaven's Feel'' route, Rider uses her Breaker Gorgon to give Shirou an EroticDream. This time, one about Sakura specifically intended to [[spoiler:motivate him to be less restrained in bed so Sakura will feel less self-conscious of her overdeveloped libido resulted from her messed-up "upbringing" as the Matou heir]]. Think of it as an IntimatePsychotherapy scenario intended to {{Invoke|dTrope}} ''another'' IntimatePsychotherapy scenario. [[spoiler:This ends up [[HoistByHerOwnPetard backfiring spectacularly on Rider]] when Shirou counters her Noble Phantasm with a projection of it, making her lose [[DreamWeaver control of the dream]] to her subconscious, soon spilling the beans about the frankly ''huge'' crush she's got on the guy and that she had managed to keep secret from him until then.]]
* TheRealRemingtonSteele: [[spoiler:A major plot point.]]
* SadlyMythtaken: ''Fate'' in general takes a fairly BroadStrokes approach to mythology (which should be obvious as soon as it's revealed that King Arthur was a woman in this story) but there's at least one outright mistake:
** When recounting the backstory of Rider and her sisters, the narration explains that Stheno and Euryale had perfect immortality, unlike the rest of the Greek gods who needed to eat the golden apples to sustain theirs. This is incorrect; it was the gods of the ''[[Myth/NorseMythology Norse]]'' pantheon who had to eat the golden apples of Iðunn to retain their youth (possibly they got mixed up with the Ambrosia the [[Myth/ClassicalMythology Greek gods]] ate, which could supposedly grant immortality, although the gods weren't necessarily dependent on it themselves).
** Rin wonders if Saber's IdiotHair is her "reverse scale", so she cuts it off to see what will happen, resulting in Saber transforming into her Alter form. However, reverse scales are only a feature of East Asian dragons -- a scale on the underside of their chins that causes the normally benevolent Eastern dragon to go berserk if agitated -- while Saber was infused with the blood of a Western dragon. Although this one could be chalked up to RuleOfFunny.
* ScrewYourself: Gilgamesh expresses an... '''interest''' in his cute younger self.
* ShoutOut:
** When Shirou goes to clean Tohsaka's house alone while she's away, he remembers her joking that if he ever becomes her live-in apprentice, he'd have to sleep in the storage room under the stairs. Shirou then wonders whether he'd count as [[Literature/HarryPotter "some kind of boy wizard"]] in that case.
** In the scene where Shirou gets AmusingInjuries after being used as the rope in a non-romantic LoverTugOfWar between Neko and Taiga (long story), the latter says:
--->'''Taiga:''' Huh? Shirou, why are you arms stretching? Rubber? [[Manga/OnePiece Did you eat some strange fruit?]]
** When Himuro -- the girl with glasses from the track-and-field trio -- comments about an ineffable discomfort she wake up to about how her own memories doesn't feel as familiar as they should [[spoiler:(possibly due to the true nature of the GroundhogDayLoop)]], Shirou asked her if it was like "[[JustWokeUpThatWay just waking up to find yourself]] [[Literature/TheMetamorphosis turning into a bug]]."
** When someone suggests that Shirou/Ayako may be a thing, Taiga ''[[LargeHam explodes]]'' and goes into a rant that compares the living arrangements at his place to [[Manga/LoveHina certain "hot springs boarding house"]].
* SickEpisode: Shirou can end up having to take care of Tohsaka at her place while she's under-the-weather in an optional scene.
* SpellMyNameWithAnS: Among other things, ''Fate/hollow ataraxia'' uses a different spelling of Illya's name than ''VisualNovel/FateStayNight'' did. They used Illya instead.
* ThirdOptionAdaptation: ''Fate/hollow ataraxia'' is a sequel, not an adaptation, but it essentially mashes together parts of all the routes in the original, while removing or ignoring things that would be contradictory or difficult to handle on a fandisc, such as most of the traumatic bits of Sakura's backstory mostly being glossed over. This is probably justified by Rin accidentally almost merging all realities a month before Ataraxia takes place, as well as the nature of the GroundhogDayLoop occurring in the story.
* TransformationSequence: Rin's MagicalGirl transformation
%%* TwoTeacherSchool
* UndeadTaxExemption: {{Averted|Trope}}. As summoned individuals, Servants have no legal identity nor employment history. Rider and Lancer get around this by holding part-time jobs, Archer simply Projects whatever he needs and remains in Spirit Form the rest of the time, Gilgamesh is just so filthy rich that can throw money at any problem he may have, and Assassin and Berserker are unable to interact with regular people in the first place. Caster is a special case who actually had to buy a forged identity from the "supervising young lady", while pointing out that it didn't come cheap, so she and Kuzuki could get married. Saber… well, Saber basically embraced her PrettyFreeloader-ness and a scene has Rider and Caster shooting potshots at her for it.
* UnlockableContent: Plenty. Completing certain scenes unlocks wallpapers, figuring out what the "cursed item" found in the Ryuudou Temple is for unlocks [[spoiler:the Hanafuda card]] MiniGame, going on dates with the main heroines unlocks an OptionalSexualEncounter for each of them in the original PC version, reading scenes increases the "funds" for the [[DevelopersRoom "Tohsaka Shrine"]], and even much of the main gameplay consists in finding and triggering the right flags to unlock more of them and advance in the main storyline.
* UnusuallyUninterestingSight: One of the first signs that something is off: Shirou, seconds after reminiscing about how the servants were gone, encounters Caster... and proceeds to see nothing strange about this.
* UnwantedHarem: The story does not have Shirou paired off with any one character. Instead, he now has Tohsaka, Saber and Sakura plus the addition of Rider and Illya while Ayako and the three track girls also seem attracted to him to varying extents. [[spoiler:A particularly entertaining scene opens up in Eclipse after you get OneHundredPercentCompletion, where Bazett and Caren both also try to move into the Emiya household, and each of the heroines vigorously protests.]]
** Averted with: [[spoiler:Bazett, even if the heroines protest about her moving in for a week, it's clear she's in love with Lancer. Caren, on the other hand, seems mildly taken with Shirou's resemblance to Avenger. This IS still an aversion, since it's mostly Avenger.]]
* UpdatedRerelease: The PS Vita port of the VN has fully voiced dialogue, a hilarious hanafuda game starring Shirou and Rin as the playable main characters, and BleachedUnderpants scenes that censor and completely remove the original game's sexual bits.
* VerbalBackspace: When Shirou goes to the pool with all the main female characters, he's surprised to find Kid!Gilgamesh in there and complain that even the owner of the resort shouldn't crash other people's party like that. Shirou then does a hilarious 180-turn in utter gratitude when Gil says he kept Archer and Lancer from trespassing the premises.
-->'''Shirou:''' ''[firmly shakes Gil's hand]'' Thank you. It seems I've completely misunderstood you this whole time. [...] ''[thinking]'' Serves them right, that damn macho Servant duo…!
* VerbalTic: Normally averted, but when the crowd gets a hold of some Einzbern spirits, each drinker gets a verbal tic based on their preferred animal. Rin talks like a cat-nya, Saber like a lion-gao, and Shirou talks like a dog-wan. In general, though, at least in the original Japanese, one can reliably distinguish almost every character simply by their natural speaking patterns, without needing to involve a lot of odd speech or particles (Himuro's odd use of archaic honorifics notwithstanding).
* WackyMarriageProposal: When her head maid kept complaining about Illya planning to have a day at the pool with Shirou due to the impropriety of it, she nonchalantly declares him her "future consort" and says that should make it okay for him to escort her. Sella's opposition is driven to a corner and [[RedEyesTakeWarning her eyes literally go red]] and glares at Shirou in barely restrained impotent fury.
* WillNotTellALie: Shirou says that he's learned that Servants generally never lie outright as a matter of pride. If you look back at ''VisualNovel/FateStayNight'' you'll see the evidence supports this conclusion. Even Archer, who says he has no pride at all, does not seem to care for lying so much as being misleading. Of course, while they won't lie, there are [[ExactWords other]] [[YouDidntAsk ways]] [[FigureItOutYourself of keeping secrets.]]
%%* WorldOfBadass
* YouRemindMeOfX: Rider is really embarrassed that she got killed by Perseus in her original life. She describes him as a loser and a spoiled brat and that he's like a "successful [[{{Jerkass}} Shinji Matou]]". In hindsight, this means her getting bossed around by Shinji in the original Fate/Stay Night must have been harsh.
