History Characters / ACertainScientificRailgun

* BorrowedCatchphrase: During the last episode of ''Railgun S'', [[spoiler:every single member of Judgment]] uses her CatchPhrase.

* CatchPhrase

* ForgotAboutHerPowers: Despite her often ingenious uses of her power, she sure gets punched in the face a lot for someone who can ''teleport instantly''. Teleportation ''does'' require some very complex mental calculations, though, so it may be difficult to use reflexively.
* FormalCharactersUseKeigo: She uses a highly refined and ladylike speech-pattern. This highlights her haughty attitude, but on the other hand, she's also a perverted lesbian.

* IfItsYouItsOkay: Oddly enough, Kuroko doesn't view herself as a lesbian. When working together with Mikoto to take down an attacker holding hostages, she denies being into girls with complete seriousness. Though she'd had her memories of Mikoto erased at the time, so its also possible Mikoto was her ClosetKey.

* SingleTargetSexuality: She only expressed interest in both Mikoto and later her mother (who is almost the spitting image of her daughter, minus being more well-endowed). When [[spoiler:her memory is wiped by the Queen]] she rejects the idea that she's a lesbian, which makes the situation she's in baffling for her since she can't help fixating over Mikoto. It may be less of a case of being a lesbian and more a case of being a [[IfItsYouItsOkay Misakasexual]].

** Kazari Uiharu: PlayfulHacker

[[quoteright:220:https://static.tvtropes.org/pmwiki/pub/images/shirai_kuroko_7.png]]

* {{Yandere}}: Kuroko obsessively lusts after Mikoto and detests Touma because Mikoto has feelings for him. Her jealous outbursts often come with {{Death Glare}}s and death threats towards Touma, but it's still more light-hearted than most examples since she never presents an actual danger to Touma and Mikoto mainly sees her as a nuisance for her sexual harassment.

[[folder:Ruiko Saten]]
!!Ruiko Saten
[[quoteright:190:https://static.tvtropes.org/pmwiki/pub/images/saten_ruiko.png]]
->'''Voiced by:''' Creator/KanaeIto (Japanese) and Creator/BrinaPalencia (English)

Uiharu's friend and classmate, a Level 0 from Sakugawa Middle School, and another member of Mikoto's quartet.

* AdaptationalCurves: In the anime, her cup size tends to go up a couple grades when her shirt comes off.
* AscendedExtra: While she has a major role in the Level Upper arc of the original manga, she's eventually shifted out of focus once that arc ends. In the anime, she's one of the lead characters, and is even inserted into scenes like ''Railgun'' Episode 1, where she was absent in the manga (she didn't even made her debut until the graviton bombings in Chapter 4). [[spoiler:She comes back in the Daihaseisai arc in the manga, managing to wander into an area she really shouldn't and meeting Xochitl.]]
* AudienceSurrogate: The only unambiguously "normal" human in the entire franchise.
* BatterUp: Occasionally carries an aluminum baseball bat. ''Even to the FinalBattle in S2''.
* BlowYouAway: Normally she's a level 0, but when under the effects of Level Upper, she gains a level 1 version of Aero Hand.
* BornLucky: She has a lot of lucky moments, for example being able to track down the bank cards with ease. [[spoiler:Then she gives [[BornUnlucky Touma]] her good luck charm during the Daihaseisai and it '''''[[BeyondTheImpossible gives him luck]]'''''.]]
* BreakoutCharacter: Popular enough by fans to be turned into one of the Railgun anime's main cast members.
* CanonImmigrant: Finally appeared in the main ''Index'' story in TheMovie, and is introduced to the light novels in ''New Testament'' Volume 9.
* ChekhovsGunman:
** [[spoiler:It's ''because'' she's a Level 0 that she's immune to the paralyzing [[BrownNote "Capacity Down"]] sound wave, allowing her to save her friends from Telestina's clutches in ''Railgun'' Episode 24.]]
** Spends most of Daihaseisai as this, including, perhaps most importantly, [[spoiler:lending Touma her charm. If she had never done that, he would never have been close enough to help out when Gensei attempted a Level 6 Shift on Mikoto.]]
* DespairEventHorizon: [[spoiler:After she uses Level Upper and realizes she'll fall into a coma soon afterwards.]]
* EarlyBirdCameo: Appears in both openings of the first season of ''Index,'' despite having never appeared in the novels.
* TheEveryman: As above, Saten is a mere mortal amongst gods and angels. Unlike most of the other characters in the series, she possesses no special abilities, and for that reason she is the easiest character in the ''To Aru''-verse to relate to, hence her surprising popularity.
* {{Fangirl}}: Of TeenIdol Hajime Hitotsui.
* TheGadfly: She likes to have fun by flipping Uiharu's skirt, which she often fails to notice until Saten brings it up later. She also enjoys messing with people like Kuroko or Mikoto herself about the possibility of Mikoto liking Touma.
* GenkiGirl: Young, cheerful, and always seems full of spirit. Except for the time when she fell into depression after [[spoiler:Frenda's disappearance]].
* HeroicBystander:
** In ''Railgun'' Episode 1, she saves a little boy from being kidnapped by a bank robber who has powers. [[spoiler:Then, in the finale she smashes the PowerNullifier Telestina is using to incapacitate Mikoto, saving the day.]]
** As of the premiere of ''Railgun S'' she may be heading for ChronicHeroSyndrome. As of the finale, she clearly is afflicted with it.
* {{Irony}}: She wanted to know who Mikoto was baking cookies for. In chapter 58 of the Railgun manga (Railgun T, Episode 9), she finally meets Touma [[spoiler: while her memories of Mikoto had been erased]].
* IJustWantToBeSpecial: The poor girl just wants an ability, even if it's only Level 1.
* LaserGuidedAmnesia: Chapter 49 of the Manga (Railgun T, Episode 4).

* LongHairIsFeminine: She has long black hair, and in accordance with that, she has a girly personality.
* LovableSexManiac: She loves to flip Uiharu's skirt just to see her panties, especially if they're in public.
* MoralityChain: Suprisingly (or maybe not), Saten is this to [[spoiler:Uiharu]] in the Jailbreak arc. Saten prevents [[spoiler:her best friend]] from making the wrong decision with a pinch on [[spoiler:her]] cheek and a soft scolding [[spoiler:despite having her own injury to worry about]].
* MyGodWhatHaveIDone: After she and her friends use Level Upper, one of her friends falls into a coma and she feels awful. Worse, she knows that she's going to follow soon as well.
* MsFanservice: The ShowerScene of the PSP game and the BeachEpisode of Season 1 ''loves'' to remind us that anime Saten has the ''best'' proportions of the Railgun quartet.
* MuggleBestFriend: Mostly to Uiharu, but also to Kuruko and Mikoto, since she has no esper abilities herself, something she [[IJustWantToBeSpecial initially hates.]]
* NiceGirl: She is very friendly and outgoing. Her greatest joy in life is sharing happiness with her beloved friends.
* OddFriendship: She seemed to have developed this with [[spoiler:Xochitl and later Frenda.]]
* PluckyGirl: Brave, optimistic and kind, nothing keeps this girl's spirits down for long!

* SeizaSquirm: Does this during the festival episode during a tea ceremony.
* ShipperOnDeck: She decides during the Sisters arc that Mikoto is probably staying out at night because she's gotten a boyfriend. She's wrong, but is apparently never corrected. When she sees Mikoto being tsuntsun around Touma, she faked an injury so that she could get the two to dance together.
* ShutUpHannibal: [[spoiler:Stops Telestina's gloating of humanity's supposed worthlessness by smashing the [[BrownNote Capacity Down device]] paralyzing her esper friends with one mighty swing of her aluminum baseball bat.]]
* SignatureHeadgear: A distinctive white-flower hairclip that is her signature accessory.
* StepfordSmiler: In Academy City, life is ''hard'' for anyone who doesn't [[PowerLevels "measure up"]].
* TooDumbToLive: She was borderline during Railgun SS. [[spoiler:She followed Mikoto into what was clearly an off-limits area thinking it was a casino, where she nearly gets killed by Olive, and then there was the issue with Xochitl blackmailing her. She didn't piece together that those attacks were real until later and decided to investigate on her own, gets caught, and was about to be "[[MakeItLookLikeAnAccident killed]]" when [[BigDamnHeroes Xochitl saved her at the last minute.]] ]]
* UrbanLegend: She's a particular fan of these, and whenever there's a rumor going around, she's usually the one who introduces them to the gang, and even seek to investigate them.
* YouLeaveHimAlone: [[spoiler:Shouts this to Therestina while smashing the Capacity Down device.]]

[[folder:Kazari Uiharu]]
!!Kazari Uiharu
!!!''[[PlayfulHacker Goalkeeper]]''
[[quoteright:210:https://static.tvtropes.org/pmwiki/pub/images/uiharu_kazari.png]]
->'''Voiced by:''' Creator/AkiToyosaki (Japanese) and Creator/CheramiLeigh (English)

Kazari is Ruiko's schoolmate at Sakugawa Middle School, and Kuroko's friend and colleague in Judgment as a Level 1 esper, famous for wearing a headband made of flowers on her head (and sometimes a surgical mask in the manga). Usually shy and humble, her personality can quickly change to overly excited, especially if it concerns the life of the upper-class (particularly anything involving Tokiwadai).

* ACupAngst: When Kuroko comments that her body is "underdeveloped", she gets upset.
* AdaptationDeviation: Prior to the release of ''Railgun'', Uiharu is not acquainted with Misaka and their first meeting takes place in the twelth volume of the ''Index'' light novel. The anime adaption of this episode, which aired after the first season of ''Railgun'', changes their dialogue to make them familiar with each other.
* AscendedExtra:
** In ''Index'', Uiharu is simply a Judgment co-worker of Kuroko with little relevance to the plot. In ''Railgun'', she is one of the main characters.
** Much like Saten in ''Railgun'', she's not really all that important outside the first story arc in the original manga. In the anime, her importance is significantly boosted.
* BadassBookworm:
** She's not a warrior in the ''least'', but her computer expertise makes her just as formidable, if not more so than, a dozen warriors in the right situations. She is in fact so good she can defeat even electrokinetic espers when it comes to hacking, including Mikoto.
** In the SP volume, she [[spoiler:jumped onto a moving truck from an overhead bridge, then deployed a parachute she was wearing as a drag brake in order to slow it down! The deceleration was so extreme that the metal handrails she was holding on to were yanked clean off the truck.]] Kuroko and Misaka, watching, state that she's in Judgment for a ''reason''.
* BeyondTheImpossible: [[spoiler:A little bit of situational usage of AIM Jammers and access to a supercomputer not only lets her change her power, which is something thought to be impossible in the series up to this point, but also dips headfirst into ''RealityWarper'' territory when she manages to weaken Kimi's power enough for Mikoto to finally beat her, presumably by shutting off whatever black hole her Dragon was feeding from. That bears repeating: the innocent little Uiharu managed to affect and cripple a ''Dragon''!]]
* {{Cloudcuckoolander}}: She seems to edge into a state like this whenever she's in front of a computer.
* CutenessProximity: Around Misuko's pet boa constrictor Ekaterina. Amusingly, the snake scared everybody else.
* CuttingTheKnot: When faced with trying to outhack Mikoto, Uiharu doesn't try to do any drawn-out battle of the brains or some superhacking - she merely accesses and then deletes all the data before Mikoto can acquire any of it, defeating her in one fell swoop.
* TheCutie: A small, cuddly and friendly breath of fresh air amongst her zanier friends.
* DeathGlare: [[spoiler:When Saten takes a lethal attack for her, Uiharu is overwhelmed with a desire for revenge to the point that she's drawn as nothing but a black blob in the shape of a person. Her boiling rage only subsides when Saten wearily asks her [[ArmorPiercingQuestion if this is really the path she wants to go down.]]]]
* DelicateAndSickly: In the manga, where she suffers from constant bouts of the flu.
* TheDeterminator: In Railgun manga Chapter 121, she falls down when trying to climb the emergency ladder to escape captivity, and her head hits the ground in a pretty nasty manner. She refuses to pass out from pain and makes herself stay conscious with sheer willpower, then proceeds to climb the ladder to the rooftop. All because she has made a promise with Saten to "not suddenly disappear".
* DidYouJustFlipOffCthulhu: In Volume 15 of ''Index'', [[spoiler: she taunts the Level 5 [[Characters/ACertainMagicalIndexDarkSide Kakine Teitoku]], even as he is torturing her, presumably in order to buy time to let Last Order escape. It would have [[KillTheCutie ended very badly]] for Uiharu if not for Accelerator's subsequent BigDamnHeroes.]]
* EarlyBirdCameo: In both openings of the first season of ''Index''.
* FlowersOfFemininity: She wears a headband of artificial flowers on her head, fitting with her girly and soft-spoken personality.
* FluffyTamer: Everyone else took one giant step back upon meeting Mitsuko's snake, Ekaterina. Uiharu stayed behind ''to coo over it''.
* GetAHoldOfYourselfMan: In ''Railgun'' Episode 23, she suffers a HeroicBSOD when [[spoiler:Telestina's true identity is revealed and she takes the children that were experimented on]], causing her to break down crying until Kuroko slaps her across the face and asks her...
-->'''Kuroko:''' [[ArmorPiercingQuestion When are you gonna stop crying?!]]
* GoodWithNumbers: [[spoiler:In a fit of desperation, she manages to tune AIM Jammers to forcibly mold her Personal Reality into something else, essentially giving her an entirely different ability, something no scientist or supercomputer in Academy City has managed. Given that the Level 5s are all walking supercomputers, this means that her computational skills are at least on par with them.]]
* HeartIsAnAwesomePower: She has a level 1 Esper ability called Thermal Hand that lets her maintain the temperature of an object she is holding. She doesn't get any special resistance to temperature though, so it can't be too hot or too cold. This power doesn't seem very useful outside of MundaneUtility but she is able to make great use of it when [[spoiler: trapped in a room with brainwashed guards. Since the guards were only ordered to act if she makes an obvious escape attempt, she intentionally overheats the computer she's being forced to work on in order to raise the temperature of the small room. The guards pass out from heatstroke while she protects herself by holding an icecube against her jugular]]
* {{Kawaiiko}}: Small, cuddly, vulnerable and prone to being the brunt of Saten's off-colored sense of humor and Kuroko's short temper.
* LaserGuidedAmnesia: In Chapter 49 of the Manga (Railgun T, Episode 4) thanks to Misaki's Mental Out.
%%* LittleMissSnarker: Towards Kuroko.

* MeaningfulName: Her given name Kazari literally means "ornament" or "decoration", while her family name Uiharu means "early spring", referring to the prominent flower headband she wears.
* MissionControl: Often plays this role due to her mastery of computer work, usually with Kuroko on the other end.
* NiceGirl: A warm hearted, caring and responsible young lady, with an occasionally cheeky sense of good-natured humor. [[BewareTheNiceOnes You still don't want to test her limit, though]]. Check OOCIsSeriousBusiness trope below.
* NonActionGuy: As a trained member of Judgment, she ''should'' be an ActionGirl with dangerous martial arts training. She... is not. Every time she goes out into the field, she gets hurt, so she stays at the office and plays support. She also can't run very fast or very far.
* OddFriendship: With Kuroko. They're close friends and coworkers, but Kuroko goes to an elite school while Uiharu goes to a relatively normal one. Kuroko is also a confident ([[SmugSuper sometimes to the point of overconfidence]]) field agent while Uiharu is a ShrinkingViolet who usually relies on her extensive hacking skills to act as MissionControl.
* OOCIsSeriousBusiness:
** Ruiko knows something is wrong when Uiharu ''doesn't'' react with embarrassment to her skirt getting flipped up.
** Chapter 124 revealed that Uiharu, the least aggressive of her group of friends, is [[spoiler:capable of being angry when Saten was injured by the enemy. [[TranquilFury In fact, she can barely hold her rage while wearing a scary expression as a negative aura keeps oozing from her entire being]], it took Saten pinching her cheek to stop Uiharu from wearing scary expression on her face]].
* PlayfulHacker: She makes hacking into high-security government databases ''without'' superpowers look like child's-play, and with a relaxed smile at that!!
%%* PluckyGirl
* RedBaron: Known as the "Goalkeeper" among hackers.

* SaltTheEarth: When she unknowingly caught Mikoto trying to hack into Academy City's main data centre and was unable to stop her, she decided to unleash Omega Secret on the database (or at least made it look like she did), which is an encryption program so complex it would take even Academy City's supercomputer 200 years to decrypt. In addition, each file is encrypted randomly, meaning each individual file will take another 200 years to decrypt. However, the encryption process is truly completely random, meaning not even Omega Secret itself knows how to decrypt it. So in one fell swoop, Uiharu made the database completely useless not only for Mikoto, but Academy City as well.
* SelectiveObliviousness: When she ran into Last Order, she did not notice her resemblance to Mikoto at all, even though she referred to herself as MISAKA.
* ShipperOnDeck: For Mikoto and Touma. When the two danced, she tried to stop Kuroko from interfering.
* TheSmartGirl: On a technological and technical level, Uiharu is the first and last line of defense our heroes turn to, such is her expertise in the realm of computers.
* SweetTooth: Even more than the others, but [[RunningGag circumstances often conspire]] to prevent her from actually eating them.
* UtilityMagic: Her power is useless in combat, but it's pretty handy for everyday life, such as keeping food warm, as well as advanced scientific purposes.
* WhatKindOfLamePowerIsHeartAnyway: As the only named Level 1 of the series so far, it's no surprise her ability seems unimpressive. Her power is stabilizing the temperature of everything she touches -- in other words, she's a human thermos.

* CatSmile: She often has this expression, usually just before planning something perverted. This usually involves her OneeSama Mikoto.

* TooDumbToLive: She was borderline during the the Railgun SS. [[spoiler:She followed Mikoto into what was clearly an off-limits area thinking it was a casino, where she nearly gets killed by Olive, and then there was the issue with Xochitl blackmailing her. She didn't piece together that those attacks were real until later and decided to investigate on her own, gets caught, and was about to be "[[MakeItLookLikeAnAccident killed]]" when [[BigDamnHeroes Xochitl saved her at the last minute.]] ]]

* ArbitrarySkepticism: Does not believe things that contradict Academy City's Power Curriculum, like Gemstone espers, Imagine Breaker, or Level Upper. She eventually learns Level Upper is real.

* FilleFatale: A bit too sexually aggressive for a ''thirteen-year-old'' girl for comfort...

** She claims she wants to protect Mikoto from Touma because she believes Touma is a perverted stalker. Guess what she normally does to Mikoto. Frankly it’s borderline appalling that she doesn’t see the irony.

* ImprobableWeaponUser: Needles that she teleports into her opponent's clothes to pin them down or into '''them''' to cripple them. Also her wheelchair. When the situation is really serious, she'll use metal rods instead of needles.

* JerkWithAHeartOfGold: She does not seem to understand that "no-means-no" when it comes to her molesting behavior towards the decidedly-straight Mikoto, but when Mikoto is down she's worried enough that she'll even support Mikoto hanging out with Touma despite her usual jealousy. Nothing else seems to cheer her up, so if she has to hand her OneeSama over to "that troglodyte" so be it.

* HeartIsAnAwesomePower: She has a level 1 Esper ability called Thermal Hand that lets her maintain the temperature of an object she is holding. She doesn't get any special resistance to tempature though, so it can't be too hot or too cold. This power doesn't seem very useful outside of MundaneUtility but she is able to make great use of it when [[spoiler: trapped in a room with brainwashed guards. Since the guards were only ordered to act if she makes an obvious escape attempt, she intentionally overheats the computer she's being forced to work on in order to raise the temperature of the small room. The guards pass out from heatstrokes while she protects herself by holding an icecube against her jugular]]

** Chapter 124 revealed that Uiharu, the least aggressive of her group of friends, is [[spoiler:capable of being angry when Saten was injured by the enemy. [[TranquilFury In fact, she can barely hold her rage while wearing scary expression as negative aura keeps oozing from her entire being]], it took Saten pinching her cheek to stop Uiharu from wearing scary expression on her face]].

* HeartIsAnAwesomePower: While initially, her esper power Thermo-Hand doesn't seem very useful besides maintaining the temperature of objects, it's eventually revealed that [[spoiler:she can actually outright manipulate temperature, capable of raising or lowering it to whatever level she wants, with the caveat that at Level 1 she only has a normal human-level of resistance to high temperatures. With that in mind, she can also maintain the temperature of one object while altering the temperature of another, such as keeping an ice cube under her shirt to stay decently cool and preventing it from melting while raising the temperature of a room enough to invoke heatstroke on other people]].

* ElectricTorture: How Mikoto usually rewards her attempts to make out with her, and always PlayedForLaughs.

* FieryRedhead: Though less violent-tempered than most girls of this trope, Kuroko still has the melodramatic and passionate personality that's typical of it.

* {{Kawaiiko}}: She plays this image up for her benefit, but she can be aggressive and very sexually forward at the drop of a hat.

* MadLove: Mikoto makes abundantly clear that she isn't into her and frequently gives her electric shocks when her sexual harassment gets too annoyed. None of this hinders Kuroko from continue pursuing Mikoto.

* PetitePride: Shows no angst whatsoever about being the least endowed amongst her friends, though that doesn't stop her from being [[HeadTurningBeauty stunned with admiration]] at the sight of [[StupidSexyFlanders Mii in a swimsuit.]]

* TomboyAndGirlyGirl: With Mikoto; she's the girly girl given her highly refined and ladylike speech-patterns and romantic fantasies.

* NoSenseOfPersonalSpace: Loves to flip Uiharu's skirt just to see her panties, especially if they're in public.

* AbhorrentAdmirer: Mikoto views her as a friend and ''just'' a friend, so she gets pissed when Kuroko tries to be, well, Kuroko. If she's lucky, she gets electrocuted. If she's unlucky, she gets ignored in favor of Touma.
%%%* AlphaBitch:

* BackToBackBadasses: With Mikoto ''and'' [[spoiler:[[RivalsTeamUp Mitsuko]].]]

* BunnyEarsLawyer: Yes, she is completely obsessed with Mikoto. But she's also an experienced fighter who is skilled in the detective/law enforcement required for her job.

* ChewingTheScenery: And Creator/SatomiArai is having a ''whale'' of a time playing this lovable psycho!
* ClingyJealousGirl: Absolutely hates it when Mikoto is spending time with Touma. She doesn't take it too well either when she learns that Mikoto does in fact like him. She also freaks out when she [[spoiler: [[MistakenForGay mistakenly thinks that Mikoto and Mikasa are getting intimate with each other.]]]]

* TheDeterminator: Overlooked a lot, but her actions in the Tree Diagram Remnant arc more or less confirm her as one.
* {{Deuteragonist}}: Kuroko is the second most important character after Mikoto.

* FieryRedhead: Though less violent-tempered than most girls of this trope, Kuroko still has the melodramatic and passionate personality that's typical of it.

* HandicappedBadass: She was confined to a wheelchair for a while. Then she teleports ''with the wheelchair'' and uses it '''as a weapon'''.

* IfItsYouItsOkay: Oddly enough, Kuroko doesn't view herself as a lesbian. When working together with Mikoto to take down an attacker holding hostages, she denies being into girls with complete seriousness.
** Though she'd had her memories of Mikoto erased at the time, so its also possible Mikoto was her ClosetKey.

* IncompatibleOrientation: She doesn't seem to get that Mikoto is straight.

%%* TheLancer: To Misaka Mikoto.

%%* LaserGuidedAmnesia: Chapter 49 of the manga (Railgun T, Episode 4).

* LegFocus: Boy howdy! And the camera ''loves'' to remind us of that whenever she's in flight or arming the darts strapped to her thighs!

* MomentKiller: Amazingly, besides the usual examples, Kuroko is this to herself. Many is the occasion where she has a heartwarming moment with Mikoto... only to have her feelings get the better of her and abruptly launch herself at Mikoto, setting herself up for a beatdown. She also has a habit of ruining Mikoto's moments with Touma.
* MsFanservice: She's the primary one of the Railgun quartet. Mind you, due to her lack of development, this is just as often played for awkward laughs as it is occasionally played erotically straight.
* MurderTheHypotenuse: PlayedForLaughs regarding Touma, even after he saved her from [[spoiler:Awaki.]]

* {{Ojou}}: Her highly refined and ladylike speech-pattern fits this trope perfectly. On the other hand, she possesses some decidedly '''un'''ladylike tropes.

* SingleTargetSexuality: She only expressed interest in both Mikoto and later her mother (who is almost the spitting image of her daughter, minus being more well-endowed). When [[spoiler:her memory is wiped by the Queen]] she rejects the idea that she's a lesbian, which makes the situation she's in baffling for her since she can't help fixating over Mikoto. It may be less of a case of being a lesbian and more a case of being a [[IfItsYouItsOkay Misakasexual]] ...

* TenderTears: A RunningGag has her crying every time Mikoto gives her either the cold shoulder or the jolt.
* ThinksLikeARomanceNovel: Is prone to endearingly romantic fantasy-segues, such as her and Mikoto taking the roles of Creator/IngridBergman and Creator/HumphreyBogart respectively in the "We'll always have Paris" misty-runway farewell of ''Film/{{Casablanca}}''.

* UngratefulBitch: Despite Touma saving her, she never thanks him and still hates him for being close to Mikoto.

* VerbalTic: "Desu no".

* {{Yandere}}: PlayedForLaughs, in relation to both Mikoto, whom she admires, and Touma, whom she detests.

* GirlishPigtails: Always has her hair in curly pigtails.

* PowerPerversionPotential: She uses her teleportation to spy on Mikoto, steal her stuff, and even steal her clothes while she is wearing them.
