->''"I’ll visit upon you the [[MisplacedRetribution utmost suffering]] with the [[SaveScumming infinite possibilities]] of [[TheMultiverse infinite worlds]]. I act once more in [[QuantumMechanicsCanDoAnything imitation of light]]."''
-->--'''Hatou Manabu'''

Hatou Manabu (nicknamed Gaku) has a very odd friend at school named Marii Yukari. Yukari has purple eyes and a bizarre way of looking at the world: she sees all other living things as robots. This has not always worked out well for Yukari, even costing her a best friend when she was younger. However, Yukari insists that the things she says she sees is true, and her vision seems to give her insight into the abilities of others.

Gaku thinks she's just weird, but she soon realizes that Yukari has unexpected talents. It seems she can fix anything, and even the police come to hear her insights. It turns out that Yukari's purple eyes are not unique in the world! However, there is one important distinction among those who see humans as other objects. Do humans appear as unimportant as objects, or do those objects appear as important as human beings?

Starting as a seemingly lighthearted series with a sci-fi premise, it quickly makes good use of said premise, turning much darker soon enough. The fast genre shifts and the surprisingly detailed use of physics concepts are some of the most prominent characteristics of this work.

''Murasakiiro no Qualia'' (or ''Qualia the PURPLE'' in English) is a one-volume science fiction novel written by Ueo Hisamitsu. The book also had an manga adaptation serialized in ''Dengeki Daioh'', which was completed after three volumes and eighteen chapters. The book was eventually released in English by Creator/SevenSeasEntertainment.
----
!! ''Murasakiiro no Qualia'' contains examples of the following tropes:
* AccidentalKiss: Hatou and Yukari's first meeting literally falls into a kiss when Yukari's trying to follow Hatou, and the latter turns around.
* AmbiguousEnding: The final chapter ends with [[spoiler: a letter written by Yukari to Gaku to be delivered to her should she die. Whether Yukari actually died or not in the final world is never confirmed.]]
* AnachronicOrder: Hatou's narration is oftentimes like this.
* AntiHero: [[spoiler: Hatou is slowly but surely becoming this.]]
* ArcWords: Hatou's considerations on storytelling are repeated in slightly different ways several times. Her struggle with how to tell the story suddenly becomes more understandable, considering we're talking about [[spoiler: a [[TheMultiverse multiverse epic]] [[TheGreatestStoryNeverTold only she has the whole, huge perspective of.]]]]
* AscendToAHigherPlaneOfExistence: [[spoiler: Hatou, who realizes the truth behind the theory of everything and becomes "nothing" that exists outside of the limitation and observation of the universe. Even saying that she exists as something that does not exist. Losing her identity as Hatou Manabu, she watches over evolution and finally sees Yukari surviving.]]
* TheAtoner: Gaku. [[spoiler: In the vast majority of worlds she denies herself happiness to try to solve Yukari's murder. She has endured numerous deaths, alcoholism, rape (implied), and who knows what else in pursuit of her goal. All because she helped Alice convince Yukari to join JAUNT.]]
** Subverted since [[spoiler: her helping Alice convince Yukari to join JAUNT wasn't necessarily the catalyst to Yukari's death. As she's been finding out ever since she's decided to try and [[SetRightWhatOnceWentWrong save Yukari]], [[FailureIsTheOnlyOption even in the possibilities/worlds Yukari doesn't join JAUNT, her death still happens]]]].
* BackFromTheDead: [[spoiler:Yukari due to TimeTravel like antics.]]
* BadFuture: Hatou [[spoiler: dies young and in not-so-nice ways in many of the parallel worlds]]. Ultimately, despite having characteristics that could make one consider it as a "good life", any future that doesn't have her achieving her goal of finding Alice [[spoiler: or later saving Yukari]] is considered bad and a rejected possibility.
* BewareTheNiceOnes: Hatou is a rather laid-back character. That is, until [[spoiler:[[KillTheCutie Yukari dies]]]].
* TheBigDamnKiss: In the penultimate chapter, [[spoiler:Hatou and Yukari share a kiss when Yukari convinces the former to live alongside her as friend rather than someone who protects her from beyond.]]
* BrainInAJar: One is shown in chapter 11. [[spoiler: It is Yukari's brain.]] Also, the real life example of Einstein's brain is mentioned.
* BroughtDownToNormal: In the ending, Hatou [[spoiler:makes a conscious decision to observe her arm as just an arm. This basically means there is no quantum uncertainty as to whether it's an arm or a phone, which more or less means she gives up her powers. She eventually loses even the memories of her multiverse!selves, but still retains the most important parts such as being friendly with Alice and making sure Yukari doesn't transfer to JAUNT.]]
* BreatherEpisode: Chapter 14 centers on Hatou becoming a MagicalGirl. It doesn't actually advance Hatou's quest to [[spoiler:save Yukari]], but does provide a shining moment of BlackComedy where she [[spoiler:uses cutesy magic to violently kill anyone who may cause Yukari's death]].
* BrokenBird:
** [[spoiler: Tenjou is the best example.]]
** [[spoiler: Alice is later implied to fit this trope as well.]]
* BusCrash: [[spoiler:Yukari dies off-screen in an unknown way about 6 months after transferring away from Hatou's school.]]
* CerebusSyndrome: The series start off relatively light-hearted, but after a time skip, it takes a dive for the darker.
* ChekhovsGun: No one would have imagined the cellphone Hatou innocently wanted to buy would end up being used to [[spoiler: re-attach her cut off arm and become a embedded means of communication with Yukari]]. But that's not where its usefulness ends. It also becomes [[spoiler: the means through which Hatou can interfere with the [[TheMultiverse parallel worlds]] by communicating with her alternate selves.]]
* CovertGroup: JAUNT is exactly this. A mysterious group that nobody knows about, apparently backed by the American government, which has no qualms with stealthy blowing up airplanes to keep their secrets... secret.
* {{Cult}}: [[spoiler:In the timeline where Hatou takes over JAUNT, it has become something of a humanitarian organization and a benevolent cult.]]
* CursedWithAwesome: Gaku's cellular phone arm. [[spoiler: She can use it to talk to parallel versions of herself]]. And it functions as a normal phone, too. But she is its battery, and overuse leaves her physically drained. She keeps sugary snacks on hand after she loses two pounds in one day from making too many calls.
* CynicismCatalyst: [[spoiler:[[KillTheCutie Yukari's death]]]] is this to Hatou, who changes completely after the event.
* DarkAndTroubledPast:
** [[spoiler: As a child, Tenjou fell off a jungle-gym, getting her body fatally wounded. And that's when the traumatizing part begins. Completely conscious, she then watches her best friend replacing her "damaged body parts" with jungle gym parts.]] This obviously still doesn't sit well with her for long years after. [[spoiler: Justifies her acting as a [[JerkassWoobie jerk]] toward Yukari.]]
** Alice [[spoiler: had a drug-addict as a mother and her grandmother initially told Alice's mother that the child was a blessing. But once Alice began to show her powers, her mother became convinced she was sent from the devil as punishment and began to be emotionally, and physically, abusive towards her]].
* DespairEventHorizon: Hatou comes dangerously close to this after [[spoiler:[[DroppedaBridgeonHim Yukari's death]]]], escaping it by hanging to the glimmer of hope she found in the form of Alice and becoming the {{Determinator}}. [[spoiler:She crosses it completely by Ch 13, willing to kill whoever JAUNT sends to get Yukari.]]
* DeathOfAChild: [[spoiler:Gruesomely. Besides her many other deaths, in one of the MagicalGirl universes, a child Hatou dies in a failed attempt to teleport through a wall.]]
* {{Determinator}}: Hatou, or rather, [[spoiler:[[TheMultiverse all of her selves from multiple parallel worlds]]]], won't give up finding the truth behind [[spoiler:[[DroppedABridgeOnHer Yukari's Death]]]].
* EarnYourHappyEnding: Gaku's plan on doing whatever she can to finally obtain a world where [[spoiler: Yukari doesn't die]]. It's just that multiple attempts of it have [[FailureKnight failed repeatedly]]. One of the universes has an earned happy ending to it. [[spoiler: Hatou has [[AscendToAHigherPlaneOfExistence practically become a non-existent-existing god-like entity]] that is watching over evolution and life on earth. Finally, Yukari is saved from JAUNT and does not painfully die. And she's the only one who can talk with Hatou. Yukari is horrified that her friend has opted for this type of existence just to save her and wants Hatou to return to her. Hatou, remembering her life as the regular Hatou Manabu, manages to break free from her strange existence and regain a body, kissing Yukari and the two are finally together.]]
* EasilyDetachableRobotParts:
** [[{{Foreshadowing}} Yukari tell's Gaku that she is a Super Robot type capable of easily swapping a variety of parts.]] Which is unusual as most of those types of robots are boys. Gaku reflects that this is why she is able to easily adapt to her cel-phone arm, [[spoiler: while Tenjou cannot emotionally accept her jungle gym parts.]]
** [[spoiler: Yukari easily and literally disassembles the serial killer, and the killer's head continues to work normally while Yukari tries to find the bug in her. At least until Yukari gets annoyed and shuts off her speech. Yukari then puts her back together just as easily.]]
* EmbarrassingNickname: Tenjou calls Hatou ''Helmet Head'' due to her haircut. It's not big news to say she doesn't like it.
* FailureIsTheOnlyOption: Somehow, in every single possibility/world, [[spoiler:[[SetRightWhatOnceWentWrong saving Yukari]]]] seems to be this. Whether or not it really is or whether Observer's Theory is really the concept to blame for it, it has yet to be seen.
* FailureKnight: Hatou. [[spoiler: She's trying each and every possibility/world out of a supposedly infinite amount in order to save Yukari. So far, she's only breaking herself further by watching her efforts turning out to be completely futile and Yukari dying again and again.]]
---> [[spoiler:"Once more, from the beginning, let's test every path, just like light. All for the sake of that single answer. After all, what other purpose does my existence serve?"]]
* {{Fanservice}}: The manga gives a long focus on the AccidentalKiss when it happens (and shows it multiple times). There's a pool scene in the first chapter, a shower scene in chapter 6, and a completely plot relevant nude scene (with Gaku's arm inadvertently hiding her chest from view) in chapter 11.
* {{Foreshadowing}}:
** The first few pages foreshadow the darker nature of the series, despite the lighthearted start.
** Tenjou's claims regarding the frightening nature of Yukari's eyes and the perspective of the world that comes with them.
** The call Hatou receives in chapter 8 is a foreshadowing of both [[spoiler:[[DroppedaBridgeOnHim Yukari's death]]]] and [[spoiler:her power of interacting with her AlternateUniverse selves.]]
** Yukari claims that she sees Gaku as an "all-purpose self-modifiable robot" that can do anything by switching parts. [[spoiler: By the end, Gaku has used her quantum leap powers to become countless other people, and after learning the Theory of Everything, she manages to transcend reality itself.]]
* FreakOut: Alice when she sees Gaku in chapter 11.
* FutureBadAss: [[spoiler:Several of Hatou's future incarnations end up like this.]]
* TheGreatestStoryNeverTold: [[spoiler: Only Hatou knows what happens in all the parallel worlds/all the possibilities, due to being able to communicate and share memories, knowledge and experience with her alternate selves.]] Thus, no one else knows the whole story.
* HeartIsAnAwesomePower: Hatou's initial power, the power to call people, isn't that great. She can only do so in darkness, it physically strains her body, and it doesn't work if someone's watching her. All in all, a normal cellphone does her job better. Yukari for instance, perceives living beings as robots and can [[RealityWarper overwrite reality]] to fit that view, and she has no noticeable limitations. However, once Hatou discovers that she can [[spoiler:contact her parallel selves]], through some creative thinking, [[SuperPowerLottery its potential blows through the roof.]]
* HeelFaceBrainwashing: [[spoiler:Yukari does this to a serial killer-or more specifically, debugs her after disassembling her so she becomes sane.]]
* HeroicBSOD:
** Hatou [[spoiler: upon Yukari's death.]]
** Again in chapter 13, once she realizes she can't be like light. [[spoiler: That one Hatou is promptly disposed off by one of her alternate selves once she falls into [[HeroicBSOD this state]].]]
* KillTheCutie: [[spoiler:Yukari.]]
* InSeriesNickname: Hatou is always called Gaku by Yukari. Only fits the super-trope since Hatou's the one who suggested the nickname.
* {{Infodump}}: '''''Lots''''', much due to the philosophical nature of the narration, and the various quantum mechanics theories explained.
* InSpiteOfANail: Oddly, the magical universe doesn't appear to be any different from all the others. For some reason, nobody else seems to be using magic there.
* InsufferableGenius: Alice can solve pretty much any equation in her head easily, and she sees herself as above normal humans.
* IWantMyBelovedToBeHappy: [[spoiler:Hatou convinces Yukari to join JAUNT. It backfires in a [[KillTheCutie horrific way]].]]
* JerkWithAHeartOfGold: [[spoiler: Tenjou acts like a jerk towards Yukari but has actually always been doing her best to try to understand her better.]]
* KilledOffScreen: [[spoiler: Yukari.]]
* LeaningOnTheFourthWall: Hatou's [[ArcWords considerations on storytelling]] count as this.
* [[MagicalEye Magical Eyes]]:
** Yukari's purple eyes see the world differently than everyone else. She sees all living beings as robots, [[spoiler: and as a consequence, her perspective is imposed on the world, leading to humans working as robots to her - she's able to fix them using mechanical parts, dismantle them (which would be the equivalent of cutting someone up for anyone else's eyes) without even any bleeding and change the programming in their brain.]]
** Alice sees equations as pictures, which makes it possible for her, an 11-year-old child, to quickly understand and solve university-level mathematical problems. However, she can only express the solutions verbally, since she has no idea how to write mathematical expressions without drawing a picture instead.
** Subverted with the [[SerialKiller culprit to the Tokyo Dismembering Murders.]] She claims to see people as lumps of meat but, as pointed out by Yukari, she's apparently just a [[TheSociopath sociopath]], fitting the definition almost to perfection.
* MagicalGirl: Chapter 14, Hatou gets into contact with a younger, parallel version of herself in a universe where magic exists. She also gets herself a costume including TransformationSequence.
* MindScrew: From philosophy to quantum mechanics, the series has a field day with this. Perception is troublesome, after all.
* MisplacedRetribution: [[spoiler: Hatou toward Alice in consequence of [[KillTheCutie Yukari's death]]. Alice never meant for it to happen. On the opposite, she truly believed JAUNT would be able to protect Yukari.]]
* MundaneFantastic: In Chapter 14, Hatou comes up with the idea that, if the multiverse theory is really as infinite as it is, it's not a far stretch to think that there is a parallel universe where magic exists. There is one.
* MsExposition: Tenjou is the one who introduces most of the [[UsefulNotes/QuantumPhysics physics concepts]] relevant for the story.
* TheMultiverse: From some point of the series onward,[[spoiler: Hatou]] can interact with all the [[AlternateUniverse parallel worlds]]. Each of these is one of the infinite possibilities for the flow of events that didn't get determined in her world.
* {{Narrator}}: Hatou.
* OlderThanTheyLook: In chapter 16, Hatou mentions that in the current universe she is in, she was 47 years old yet looked like she was still in her twenties. On a technical standpoint, ''every'' Hatou can be this due to the constant universe-hopping.
* [[Personal Perception Filter]]: [[MagicalEye Yukari's eyes]] mean she sees the world through one. All living beings look like robots to her. This actually takes it one step further, as her perception is actually [[ClapYourHandsIfYouBelieve capable of influencing the world around her]] through the nature of her interactions with it.
* PreemptiveShutUp: After not showing up for a couple of chapters, this is all Tenjou gets from Hatou in chapter 13.
* ProtagonistCenteredMorality: Justified. The entire story is told from Hatou's perspective.
* PutOnABus: Yukari. Though [[BusCrash not for long]].
* QuantumMechanicsCanDoAnything: While actually accurate in its explanation of physics concepts, as a science fiction, it abuses physics, and in particular quantum mechanics, to quite some extent.
* UsefulNotes/QuantumPhysics: Concepts which the series uses to great effect. The Wave-Particle Duality, the Wave Function Collapse, the-much-loved-by-fiction UsefulNotes/SchrodingersCat thought experiment and the Copenhagen and the Many Worlds interpretations of Quantum Physics. All of these are mentioned along with a simplified explanation and end up being core concepts to the series, which [[QuantumMechanicsCanDoAnything abuses them by applying them to the macro-world.]]
* RealityWarper: [[spoiler:Yukari '''and''' Hatou. Yukari is explained above under [[MagicalEye Magical Eyes]], whereas Hatou isn't as noticeable. Hatou instead is changing reality to her vision by means of [[SaveScumming infinite do overs]].]]
* ReedRichardsIsUseless: Completely averted. [[spoiler:Hatou takes full advantage of her massive information network to expose JAUNT's corruption and overtake it as its leader. Soon after, she uses knowledge from her financially-successful parallel selves to start a company to provide funding for the institute.]]
* RevengeBeforeReason: [[spoiler: Hatou in some of the parallel worlds/possibilities. To some extent, most of them fit this, considering none dropped their crusade, not even for a chance at a good, stable life.]]
* RippleEffectProofMemory: [[spoiler:Hatou]] can share memories, experience and knowledge with her selves from [[AlternateUniverse parallel worlds]].
* SacredFirstKiss: Gaku accuses Yukari of stealing her first kiss (which she did), but waves it off when Yukari takes her joke seriously.
* SaveScumming: Hatou. From the moment [[spoiler: she can contact her alternate selves from parallel worlds, she is akin to a quantum computer, being able to find out all possible outcomes and pick the one she's interested in.]] She basically has unlimited lives/save files, even if she happens to die.
* ScienceFiction
* ScrewDestiny: In Chapter 13, Hatou thinks that [[YouCantFightFate ]] might be the reason why [[spoiler: she can never prevent Yukari's death in any of the worlds]]. In Chapter 14, Hatou thinks that this is bullshit and says she doesn't believe in "fate" and ''will'' continue to screw "fate" over if it really is why she doesn't succeed.
* SerialEscalation: Hatou's power starts off as nothing more than having a cell phone embedded in her hand. Eventually, it gains the power to [[spoiler:communicate with her selves from parallel universes]]. Then, we have this evolve into a [[spoiler:full-blown information network]] and from there, [[spoiler:MentalTimeTravel]]. Shortly afterwards, it escalates into [[spoiler:mind-controlling humans with even the tiniest of blood relationship]] and [[spoiler:reality warping.]]
* SerialKiller: The culprit to Tokyo Dismembering Murders.
* SetRightWhatOnceWentWrong: Hatou. [[spoiler: She's now trying to find a possibility/world in which Yukari's death doesn't happen.]]She [[FailureKnight hasn't been very lucky thus far]].
* ShoutOutThemeNaming: Just as Alice is named after the ''Literature/AlicesAdventuresInWonderland'' protagonist, the girl from JAUNT [[spoiler:that replaces her when she dies in one timeline]] is named [[Literature/TheWizardOfOz Dorothy]] [[Creator/LFrankBaum Frank]].
* ShownTheirWork: For its short length, ''Qualia'' has some good use and explanation of scientific concepts:
** For example, Chapter 7 has Tenjou and Manabu talk at length about how Marii's powers work, and mention UsefulNotes/SchrodingersCat in the middle. Manabu thinks that the "1/2 alive, 1/2 dead" misconception is bogus, and in a rare moment of fictional coversations about it Tenjou ''agrees'' that it sounds preposterous--because it is and always was.
* TheSociopath:
** The culprit to Tokyo Dismembering Murders fits the trope quite well, from putting the [[ItsAllAboutMe selfishness in achieving the answer]] to her [[OurSoulsAreDifferent prized philosophical question]], to her her perfect LackOfEmpathy.
** Hatou steadily becomes this, as she with each jump, she becomes more desensitized to anything, but her goal.
* [[HeKnowsTooMuch They Know Too Much]]: [[spoiler: JAUNT blows up the entire plane in order to dispose of Hatou and Yukari's family, who were traveling to America, because they were prying into the [[DroppedaBridgeonHim incident]] that resulted in [[KillTheCutie Yukari's death.]]]]
* ThemeNaming: Aside from Marii, three characters are named after what is considered the first Japanese robot, Gakutenshou. Gaku went to Manabu, Ten went to Tenjou, and Shou went to Tenjou's crush Kasoku Tomonari.
* TimeTravel: [[spoiler:Hatou figures out how to go back in time in order to SetRightWhatOnceWentWrong.]]
* TookALevelInBadass: Hatou[[spoiler:, from the moment she decides to find out more about Yukari's death.]]
* TraumaInducedAmnesia: An uncommon variant where said amnesia doesn't happen right after the fact but several years later. [[spoiler: To get over her [[DarkandTroubledPast childhood trauma]] caused by Yukari's [[MagicalEye Magical Eyes]], at least in one of the parallel worlds, Tenjou, sometime in between the last year of middle-school and age 25, chose to re-observe her past and completely forget about those troublesome and traumatic events.]]
* WhamEpisode: It can be said that the series is full of [[WhamEpisode Wham Episodes]], a natural consequence of SerialEscalation, but there are some notable moments:
** Chapter 6 finally reveals the peculiarities brought along with Yukari's eyes. And they're creepy, at the very least.
** Chapter 10:
---> "This is the PointOfNoReturn. You have been warned."
* WhamLine: Chapter 8
---> [[spoiler:"A call that should have been impossible... yet I recognized the voice who told me that Yukari would die. The person at the other end of the receiver... was me."]]
* WiseBeyondTheirYears: Nanami frequently talks about things beyond her age in conversations with Hatou, bringing up things like the philosophical zombie and quantum physics. [[spoiler:Due to her RippleEffectProofMemory, Hatou has the knowledge and experience from several lifetimes, shared between the infinite possibilities of her self, which undoubtedly makes her this.]]
* {{Yandere}}: [[spoiler:Hatou seems to have jumped straight into this, especially at the end of Ch 12. Ch 13 only solidifies it.]]
* YouAreWorthHell: Hatou is willingly putting herself through hell for Yukari. [[spoiler:[[SaveScumming Countless times]]]].
* YouCantFightFate: Hatou mentions this in chapter 13. According to her, [[spoiler: it might be the reason she can't save Yukari no matter what]]. Complete with a neat mention of the Observer's Theory as well.
* YouKillItYouBoughtIt: Intentional and rather peculiar variant in that we see [[spoiler: one Hatou murder one of her alternate world selves to then take her place as what we could call the "main" one.]] In truth this imagery is akin to rejecting a possibility/world, but being presented in this way just makes it quite a bit more powerful a scene.

She eventually loses even the memories of her multiverse!selves, but still retains the most important parts such as being friendly with Alice and making sure Yukari doesn't transfer to JAUNT.]]

* BrokenAesop: [[spoiler: One of the themes presented is that everyone is in charge of their own fate, and no one should impose their will on another even if it's for the recipient's benefit. However, Yukari's power itself is a contradiction, as her perception is imposed on the world in which she can manipulate at will. In fact, the plot really kicks off by Yukari saving Gaku by implanting the cell phone in her arm, without Gaku's consent.]]

The original work comes in the form of a novel, written by Ueo Hisamitsu, which consists in a single volume. The series also had an ongoing manga adaptation serialized in Dengeki Daioh which completed after three volumes.

* TheCutie: Pretty much everyone in the story agrees that Yukari is a cutie.

* OutOfFocus: While Yukari is the deuteragonist of the story, she appears less and less as the story goes on and the focus is more the physics and parallel worlds. It makes it difficult to recall that the story originally started off to [[spoiler: prevent Yukari's death through travelling to paralell universes]].
