Mikoto, also known as "Biri-Biri"/"Bug-Zapper"
, is the main female Science-oriented protagonist of the Index
universe and near-eponymous protagonist of her own spinoff, A Certain Scientific Railgun
. Her power is Electromaster
, and with it she is the third most powerful Level 5, the highest rank attainable for an Esper. Has a love/hate relationship
Provides examples of:
- Accidental Misnaming: Is rather annoyed that Touma keeps calling her "Biri-Biri" and kept telling him it's not her name. In the epilogue of the Sisters Arc, after she fails to give him her homemade cookies, she once again insists on him using her real name, to which he finally does indeed say it. Although the audience can't see, Kuroko mentioned that she had never seen that expression on her face before.
- A-Cup Angst: It does not help that some of Academy City's younger girls are better endowed than she is. And it's hinted that Misuzu (who's well endowed herself, also to her daughter's chagrin) wants to rectify this fast (through food). Considering she's no more than fourteen, one would have to wonder why she's so bothered about it. This is again Played for Laughs during her first meeting with Misaka WORST. Due to WORST being an age-accelerated clone of Mikoto, this should mean that Mikoto will (literally) grow out of this, but WORST trolls her about it, noting that she was grown using different hormones, and thus there's no guarantee that the others will reach her proportions.
- The Ace: She's known as "The Ace of Tokiwadai", and she backs it up by being one of Academy City's most powerful espers.
- Action Girl: She has slightly violent tendencies, and is ranked third among the Level 5 Espers.
- Alliterative Name: Mikoto Misaka
- All-Loving Hero: Sort of becomes one in the anime-exclusive arc in Railgun S.
- Armor-Piercing Slap: Subverted. Try as she might, Mikoto just cannot get a hit in on Touma.
- Ascend to a Higher Plane of Existence: Gensei co-opts Exterior and the Misaka Network to forcibly induce a level 6 shift on her, which basically means becoming an angel. However, while Accelerator could hit level 6 and retain his mind and body and Kakine has a chance of doing the same, in her current state Mikoto would lose her personality when she was halfway there and would self destruct when reached full power and tried to ascend, since there's no more room in Heaven for any more angels.
- Ax-Crazy: In Episode 4 of Railgun against Touma.
- Badass Adorable/Cute Bruiser: She looks cute and innocent, which causes a lot of guys to hit on her. Unfortunately for them, she's also one of the strongest people in the city and has one of the most flexible powers in the entire story.
- Batman Can Breathe in Space: In the Railgun S season finale, she and Kuroko were launched to the edge of the atmosphere without suits. While seemingly unaffected by the vacuum, they were visibly choking before they made it back to Earth.
- Belligerent Sexual Tension: Touma is the only one that can bring out her true tsundere side, though Kuroko's attempts to molest her are annoying enough to get similar results. It takes her around 15 novels to even realize and admit the reason for her behavior.
- Berserk Button: There are only two things that make her angry enough nearby objects start sparking: threats to the Sisters, and Touma.
- Big Damn Heroes: Twice to Lessar in the second Railgun SS.
- Big Sister Instinct: Loves the Sisters as though they really are her siblings, and would go to hell and back to protect them. Which is exploited by Gensei Kihara.
- Blood Knight: Though more from her inability to forgive slights than actual bloodlust, because she will forgive you after pounding your ass in.
- Blush Sticker: At times, especially as a child, if Last Order is any proof.
- Breaking the Fourth Wall: Once in New Testament Volume 2.
"If she let him get away, things would get very bad."
"To put it in concrete terms, it was possible that she would end up with no scenes for three whole volumes."
"Wait! Wait just a second!! This is my scene! If you’re going to do this, do it later!! Dammit, the guy-to-girl ratio here is completely out of balance. And is that group of huge breasts specifically targeted at me!? A-at this rate, I’ll be lost in the background…!! Did they create a forest to hide a leaf!?"
- Breakout Character: She started as just another Girl of the Week, but proved so popular that she began to both appear more frequently, though still had little effect on the plot until World War III. She muscled her way into the story proper during the start of the New Testament novels and even got her own spinoff which has proven at least as popular as the main series.
- Break the Cutie: During the Sisters Arc, resulting in a Heroic BSOD.
- Brought Down to Badass: During the Sisters arc, she's been going around trashing facilities for several days without eating or sleeping and is completely exhausted. After using the last of her energy to fight off Frenda, she's pitted into combat with Mugino and manages to use Frenda's explosives, a few passive effects of her electromaster powers and knowledge of the facility to bring Mugino down without enough power to use a single electric attack.
- Catch Phrase
"Do you know what a railgun is?"
- Cannot Spit It Out: To Touma.
- Character Development: Her primary flaw in the early series is pride; as one of the most powerful espers in the city, it's hard for her to even consider that there might be things she can't do and needs help with. As the series progresses, she evolves into a character more capable of accepting support from others and trusting people (especially Touma) to be able to solve problems on their own.
- Chronic Hero Syndrome: Despite Kuroko constantly warning her that since she is a civilian, she should leave the heroics to Judgment or Anti-Skill, she just can't help jumping in and helping. Ironically, Mikoto can't understand why Touma does the same thing.
- Clingy Jealous Girl: Although it doesn't pop up too often, she's not too fond of how close Index is to Touma. And when he's seen hanging out with one of the Misaka sisters in episode 18 of season 2's A Certain Magical Index, she gets angry with him.
- Cloning Blues: The Sisters.
- Code Name: See above.
- Cool Big Sis: Acts like this, especially in the Railgun series. Less so in the main series, since she hangs out a lot more with Touma who brings out her Tsundere side.
- Cry Cute/Tears of Remorse/Tender Tears: Breaks down crying while she cradles a hideously injured Touma in her lap after brutally electrocuting him, realizing his point about the futility of trying to fight Accelerator to the death, noting how it will ultimately solve nothing.
- Cunning Linguist: Besides Japanese, she knows other languages like English, French, and Russian. It comes in handy when communicating with the French-speaking Cendrillon.
- Cuteness Proximity: Frogs, especially a mascot named "Gekota", so much so she thinks she sees a real-life version of it in the form of Heaven Canceller, of all people.
- Death Seeker: Was planning on doing this, both in hopes that were she to lose to Accelerator on the first move, the calculations made for the experiment will be invalidated, as well as to atone for the suffering she put the Sisters through. Touma points out the flaws to her plan (even to the point of refusing to defend himself when Mikoto tried to zap him out of her way), that she won't be saved, and her death will not give the Sisters happiness, meaning in the end, no one will be saved.
- Despair Event Horizon: During the Sisters arc, she constantly sacrifices sleep and fights constantly to the point of nearly passing out to stop the project. After seemingly wiping out every facility, more pop up and function in a way that actually benefits them if more shut down and then her last hope of using the Tree Diagram fails when she learns that it was destroyed. Upon learning this, she realizes she just can't stop the experiment and intends to go and commit suicide in a manner that will hopefully invalidate the premises the experiment was built on and end it.
- Double Standard: Abuse, Female on Male: Frequently throws lightning at Touma whenever he does something to piss her off, and has tried hitting him with attacks that would very well have killed him if he didn't nullify them in time. Justified from her perspective because she thinks that he's just holding back and would just nullify them anyways. In the few times where he doesn't nullify them, she's shocked and realizes just how serious the situation has become.
- The Dreaded: Once delinquents realize that they are trifling with The Railgun of Tokiwadai, the smart ones will invariably drop their weapons and run in terror.
- Electric Torture: Played for Laughs as a Running Gag — this is how she usually rebuffs Kuroko's attempts to make out with her.
- Elegant Classical Musician: Yup.
- Embarrassing Nickname: Touma used to call her "Biri-Biri" ("Bug-Zapper"), a name she doesn't like.
- Erotic Dream: Has one of Touma in the beginning of Season 2 Episode 17.
- Even the Girls Want Her: Much to her chagrin. During the school festival episode multiple students try to give her gifts.
- Failure Is the Only Option: All her attempts to stop Level 6 Shift are squashed by Academy City's administration before Touma lent a hand.
- Flight: When she's over a body of water, she performs hydrolysis on the water particles so she can propel herself and fly.
- Genre Savvy: She can read Kuroko like a book, and knows better than to take any gifts from her without making sure they're not laced with aphrodisiacs.
- Glass Cannon: She´s one of the most powerful characters in the Toaruverse, but when Touma had his hand in hers to shut down her electric powers and had his other hand raised, she closed her eyes in fear and nearly started crying, as he himself lampshades that it´s hard to hit someone with a face like that.
- Goofy Print Underwear: Kuroko finds out, much to her delight, that Mikoto's panties share the same "thumbs-up bunny" logo that the T-shirt she was given as a present has... then she just had to sing that aloud. This is perhaps the reason Mikoto wears Modesty Shorts.
- Hair Decorations: Her head progressively collects cute hair clips over the course of the series.
- Hair Flip: On occasions.
- Hair-Trigger Temper: Is rather quick to anger over the smallest of slights, and has a vengeful streak three-miles-wide towards those who personally wrong her (namely Touma earlier in the franchise, chronologicaly); that said, she WILL forgive (and even befriend) you after she has exacted vengeance by pounding you into the ground.
- Hard Work Hardly Works: Subverted, as her quick ascent up Academy City's rankings is often held up as an example of how anyone can succeed with hard work, However, with the revelation that the scientists behind the Sisters experiment obtained her DNA map when she was at a lower level, and the much later revelation of the existence of the parameter list, this becomes a Double Subversion, since these mean that Mikoto had actually been pegged for greatness very early on in her development and was helped along the way much more than the average student.
- He Is Not My Boyfriend: She gets put into this situation by Index, her friends, in front of Touma and their parents too (cue massive blushing). She keeps denying it, but no one believes her.
- The Hero: Shares this trope with Touma in her own series.
- Heroic BSOD: After seeing one of her sisters die and being unable to do anything to stop it.
- Hero with Bad Publicity:
- A plot point during the Shopping Mall Demonstration SS. Using a method of spreading rumors of a possible nuclear attack by her, every rioter in the area targeted her with rifles, axes, and every other weapon they could. This also counts as Mugging the Monster because if she wasn't The Fettered, she could have simply electrocuted them all and been done with it.
- She is also known in the 7th District as 'that crazy bitch from Tokiwadai' for screwing with people's phones with her power.
- Hey, You!: She has yet to call Touma by his name. Save the PSP game intro
- High-Pressure Emotion: In more comedic scenes, she is prone to sudden puffs of steam to accompany her Luminescent Blushing to emphasize how vulnerable and embarrassed she is about feeling romantic-love towards Touma.
- Honor Before Reason: She has a big problem with asking others for help.
- Hot-Blooded: More so than the comparatively laid-back Touma.
- Hypocritical Humor
- She makes fun of Touma for losing a 2000 yen bill to that evil vending machine, but in her first year she lost a 10000 yen bill to it, which is why she feels so justified in kicking and shocking it.
- She gets mad at Touma for always calling her Biribiri instead of her name, but she never uses his name either. He's always 'you' or 'that guy' or 'idiot'.
- I Am Not Left-Handed: First, she can release a lot more electricity than she normally does, it's just that she typically holds back to avoid killing people. Second, she can use metal objects other than coins for her railgun attack, and the larger the object, the farther it can travel (since her range is due to the object vaporizing from air friction).
- Identity Amnesia: She forgets who she is in her angel form.
- Jerk with a Heart of Gold: Short-tempered, vengeful and petty over the most childish-reasons, Mikoto is nevertheless kind-hearted and considerate to a fault, and unfailingly loyal to those who earn her respect/friendship.
- Kindhearted Cat Lover: Mikoto has a huge soft-spot towards adorable baby animals, kittens in particular. To her disappointment, the ambient electricity generated by her sheer power causes discomfort in the poor little things, driving them away whenever she tries to play with them. This is a trait that the Sisters inherit from her.
- Last Name Basis: Virtually everyone refers to her as Misaka. This is inverted in the fandom, where (due to the vast number of characters who can be called "Misaka") she's almost exclusively referred to as Mikoto.
- Limp and Livid: Accompanied by furious shaking whenever she is about to go ballistic on Kuroko for her latest act of immature stupidity.
- Little Miss Badass: Don't let her cute appearance fool you; this young lady is regarded as the third-most-dangerous person in Academy City for a very good reason.
- Locked Out of the Loop: Is constantly left out of Touma's adventures. Even late into the New Testament series, she doesn't know about Imagine Breaker and thinks Touma can just negate things in general.
- Love at First Punch: Mikoto became interested in Touma after he first blocked her electricity while she was zapping some delinquents.
- The McCoy: Between Touma's Kirk and Accelerator's Spock
- Megaton Punch: The most common method to stop a clingy Kuroko.
- Mistaken for Gay: When Kuroko met Mikoto's parents, acting her usual perverted self towards Misuzu (who thinks it's towards Mikoto), with the latter lampshading that her daughter may be lesbian.
Misuzu: Mikoto, I didn't know you swung that way.
Mikoto: No I don't!
- Modesty Shorts: Trope Picture. Much to Kuroko Shirai's dismay.
- Ms. Fanservice: Side by side with Kuroko, she is most often portrayed in shower scenes and situations that show/emphasize her trim-and-firm, athletic figure.
- Mundane Utility
- She can use her electrical powers to cook.
- Uses what she learned from the Power Curriculum, the same training that allows her to make micro-second calculations in order to utilize her ability, to count cards in poker.
- In one Railgun omake chapter, it's shown that when Mikoto and Kuroko are feeling lazy, they just stay in bed, with Mikoto activating appliances from a distance and Kuroko teleporting things.
- Names to Run Away From Really Fast: She's called the Railgun and is a Level 5. What did you expect?
- New Transfer Student: In New Testament 5, she's planning on taking the entrance exam for Touma's school.
- No Guy Wants to Be Chased: Well, Mikoto is a girl, but the chaser is female. In any case, Kuroko's clingy, perverted and creepy behavior clearly gets on Mikoto's nerves while she's friendly and generous to everyone else not named Touma. And unlike Touma, poor Kuroko isn't getting the tsundere treatment but rather the Vitriolic Best Buds treatment.
- No Sell
- An electric field around her prevents the Queen of Tokiwadai from tampering with her mind. Presumably, this also means that she's immune to other brainwashing and telepathic abilities. In chapter 61, Gensei Kihara finds a loophole. She's immune to a level 5's mind control, but the MISAKA network is not. So he uses Exterior to take control of them, fuses them to Mikoto, and then controls her indirectly through them.
- When she attacks the second to last lab in the Sisters arc, she runs into a prepared battlefield absolutely filled with various traps set by Frenda. However, no matter what Frenda throws at her she just defuses it or uses magnetism to avoid the attacks, leaving Frenda increasingly uncomfortable with the power her opponent must have.
- Oblivious to Love: She's actually oblivious to her own love. It takes her until Volume 16 to realize that she likes Touma.
- Offhand Backhand: In her fight with Touma during the Sports Festival (when she's in her angel form), she doesn't even look at him. She just casually sends ludicrously large bolts of electricity at him while trying to think of a way to destroy the Windowless Building. It doesn't work, because it's Touma, but she still treats him as a persistent fly rather than a serious threat.
- Ojou: Everybody in Tokiwadai treats her as one. While she has the wealth and the status, she prefers to act like a tomboy with childish habits and is annoyed that everyone expects her to be a proper lady.
- One-Man Army: She can take on entire Black-Ops battalions armed with automatic weapons with ease. Quite a few low-level mooks will surrender instantly when they realize who they're fighting.
- One-Winged Angel: Beginning the Level 6 Shift comes with an appearance shift into a demonic form. She becomes less human looking as time goes on.
- Onee-sama: To Kuroko and a legion of admirers.
- Only Sane Man: She's the only one of the Level 5s that is considered publicly presentable and has become something of a mascot as a result despite her own quirks that keep her from being showcased too much. Accelerator and Kakine are antisocial murderers, Mugino appears normal but only until she gets angry, Misaki is paranoid and abuses her powers, Gunha is convinced he's a superhero, and the sixth Level 5 apparently never appears in public. Mikoto, by contrast, is just a tsundere tomboy with childish tastes. This is also only because the higher ups used mass media/rumors to create her ideal image and covered up Mikoto's various incidents.
- OOC Is Serious Business: Kuroko gets extremely worried whenever Mikoto doesn't zap or reject her.
- Our Angels Are Different: In chapter 61 of the Railgun manga, she begins to Awaken to her angel form when fused with the MISAKA network. In the next chapter, while she is only two percent of the way to level 6, she calls down the strongest lightning strike ever recorded, and is specifically mentioned to be dozens of times more powerful than normal. She also learned how to teleport.
- Out of Focus: In the Index series, where, despite often being billed as a main character, she hasn't been very plot relevant since the Sisters Arc.
- Recognition Failure: Despite being the face of Academy City, the average citizen does not recognize her on sight, and many street thugs assume she is just a helpless girl and try to mug or sexually harass her.
- Red Oni, Blue Oni: The Red to Touma's Blue.
- Required Secondary Powers: She's explicitly noted to be immune to electrical attacks when a girl tries using a taser on her. If she doesn't fry herself, what good is a taser going to do?
- The Rival: In the Index series her rival is Index for Touma's affections. In the Railgun series her rival is Shokuhou Misaki the Queen of Tokiwadai, the other level five at Tokiwadai.
- Running Gag: Her love of things considered childish, including Gekota (a Hello Kitty like character) Goofy Print Underwear, childish pajamas and a ruffly swimsuit, all of which she denies when asked about.
- Self-Made Man: Mikoto climbed all the way from Level 1 to Level 5 through hard work, but this is also subverted when it was revealed that Academy City's higher-ups can predict an esper's development.
- She's Got Legs: The camera loves to focus on this fact as much as Kuroko.
- Shrinking Violet: Occasionally when around Touma.
- Shock and Awe/Lightning Can Do Anything: The nature of her abilities. She's called "Railgun" for a reason.
- Convection Schmonvection: Averted in Railgun Episode 12 where, against an opponent deploying a barrier that nullifies electric shock, Misaka uses the massive amounts of heat generated by her lightning to melt the thing.
- Cursed with Awesome: Has a constant electrical field around her and cats won't go near her because of it.
- Extra Ore Dinary: Can use her lightning abilities to control magnetism and therefore control metal. She can even use iron sand to make a Whip Chainsaw!
- Finishing Move/Limit Break/Magnetic Weapons/Weapon of Choice: Her railgun was called as such a few times.
- Hollywood Hacking/Technopath: Though not at Uiharu's level, she can use her powers to directly interface with electronics and hack them.
- Kill Sat: She can more or less drop cloud-to-ground lightning on targets. And there's the bolt she drops in chapter 62.
- Money to Throw Away: Her Railgun uses coins which she can launch at three times the speed of sound using her electricity.
- Power Incontinence: Whenever she gets angry she usually short-circuits an entire block.
- Selective Magnetism: An integral part of her railgun.
- Teleportation: She can teleport herself when she's in her angel form, though exactly how this works is not examined in depth.
- Wall Crawl: By magnetizing herself, she can stick to walls and ceilings. Mugino nicknames her "Spider-Woman" for it.
- Wave Motion Gun: Her railgun, full stop.
- Shown Their Work: Unlike most of the Technobabble in the series, Mikoto's railgun is actually surprisingly plausible. The effects shown fall into Artistic License a bit, but an MIT physics graduate found that the numbers we're given add up realistically.
- Shut Up, Hannibal!: Delivered to Therestina via railgun.
- Strong Family Resemblance: To her mother.
- Shorttank: And one who is quite embarrassed to show any sort of girlish behavior at that.
- Stalker with a Crush: Although at that point the crush part was debatable, Mikoto did follow Touma quite excessively (including once chasing him around for a whole night).
- Super Mode: In chapter 61 of the Railgun manga, Misaki's Exterior is used to force Mikoto to join with the MISAKA network in another attempt at a Level 6 Shift.
- Swiss Army Superpower: Normally, you'd consider generating electricity to be a fairly limited power. However, it's proven quite flexible.
- She can of course zap you directly.
- While based pretty solidly in physics, the author makes a point of noting that a resistor is only worth so much against electricity: That energy has to go somewhere, meaning it turns into heat instead.
- She can manipulate current in order to create a railgun in the air and fire small objects with it, coins being her favorite. This is the source of her nickname.
- Electric current running through her body makes her immune to mind reading, mind control and electric attacks.
- Control of electricity equals control of electromagnetism apparently, so she can can control metal to make weapons and shields or walk on surfaces that have metal in them. This could be a wall, or it could just as easily be something that's magnetic but moving far too quickly for a normal person to stand on like a plane wing.
- Being able to control electricity also makes her a supremely capable and quick hacker, even of military grade equipment with far more security than our own.
- She never does it herself until forced to during an experiment to see if she could become a level 6, but states that through the use of bioelectricity you can form a network of a large number of minds, which is the center of at least two incidents she's involved in.
- She can redirect attacks that are electron-based, even if they are not explicitly electrical, such as Meltdowner.
- She can put out jamming frequencies, though apparently it's something of a brute force solution that jams all local frequencies.
- If her muscles are paralyzed, she can manually control them by mimicking the normal functions of the nervous system.
- Finally, she passively generates electricity at all times, which functions as a sort of personal radar. It's impossible to launch an attack from her blind spot because she doesn't have a blind spot.
- Tomboy and Girly Girl: The tomboy to Kuroko's girly girl.
- Tomboy with a Girly Streak: She wears shorts under her skirt, and when allowed seems to prefer to do away with the skirt altogether. She's a bit violent and seems to enjoy a friendly fight. She's also a complete sucker for cute childish gekko items, and she likes large stuffed animals.
- Trigger Happy: In the first episode of Railgun S she zaps a bunch of guys that had been chasing Saten (all at once) who were confronting Kuroko and Uiharu. She then reminds Kuroko and Uiharu the shop they want to go to will close soon then she says "By the way, who were those guys?"
Couldn't you have asked that before
you shocked them, Onee-sama
- Tsundere: Type A towards Touma. Kiyama, of all people, actually lampshaded it.
- Unknown Rival: For Touma. Since his memories were destroyed he doesn't remember beating her the first time. After they are reintroduced, he still doesn't take her seriously.
- Unstoppable Rage: While destroying the facilities involved in Level 6 Shift Project (especially in the case of one she attacked after she found out Tree Diagram had been shot down, ruining her plan of hacking it to save her sisters).
- Weirdness Censor: She already met several sorcerers and saw spells performed on a few occasions, but each time she either attributes it to esper powers or some other scientific explanation due to Academy City's abundance of espers. The one time someone tried explaining that's not how it works, they gave up before they even got to the point because Misaka asked a question while still trying to frame it from a scientific viewpoint.
- When She Smiles: In Railgun S when the storyline starts to merge with Index's Sisters arc, after six episodes of running herself extremely ragged, not sleeping or eating, all to try to stop the Level 6 Shift project.
- Wide-Eyed Idealist: At first, she had an idealistic view about Academy City. However, after the events of the Sister's Arc and experiencing first hand Academy City's dark side, she became more cynical, but avoided showing it in front of her friends.
- With Great Power Comes Great Insanity: Implied. Gensei Kihara states that once she's 53% of the way to Level 6, she will lose her human personality.
- "World of Cardboard" Speech: In New Testament Volume 6, when she explains why she's helping Touma to her opponent, the Valkyrie Brunhild Eiktobel.
You don't need a good reason to save a friend. If you want to save them, then save them. …I know someone who kept saying those stupid things even when he was driven to the brink of death, and he really did save over 10,000 people in the end. And that idiot that saved so many people is trying to save someone today like always. I know I can't stop him. No matter how much I don’t want him to do anything dangerous, seeing him off with a push to the back is the sign of a good woman!!
- Wrestler in All of Us: One of her methods to stop a clingy Kuroko.
- You Are Not Alone: When she properly reunites with Touma in New Testament Volume 2, she says this to him. Word of God states that she's now "entering the fight", meaning she's going to involve herself with Touma's adventures with the Magic Side. Sadly, she got dumped in the very end of New Testament Volume 3. Of course it didn't stop her from helping him in New Testament Volume 6.
Mikoto's underclassman and roommate in Tokiwadai Middle School, a Level 4 Esper, and member of Judgment. She has an obsessive crush on Mikoto, who she calls "Onee-sama
" ("Sissy" in the dub), and is on the constant lookout for a chance to... get close to her (which Mikoto rarely allows, let alone appreciates).
Provides examples of:
Uiharu's friend and classmate, a Level 0 from Sakugawa Middle School, and another member of Mikoto's quartet.
Provides examples of:
- Adaptational Attractiveness/Adaptational Curves: In the anime, her cup size tends to go up a couple grades when her shirt comes off.
- Ascended Extra: 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). She comes back in the Daihaseisai arc in the manga, managing to wander into an area she really shouldn't and meeting Xochitl.
- Audience Surrogate: The only unambiguously "normal" human in the entire franchise.
- Batter Up: Occasionally carries an aluminum baseball bat. Even to the Final Battle in S2.
- Blow You Away: Normally she's a level 0, but when under the effects of Level Upper she seems to gain some sort of wind ability.
- Born Lucky: She has a lot of lucky moments, for example being able to track down the bank cards with ease. Then she gives Touma her good luck charm during the Daihaseisai and it gives him luck.
- Chekhov's Gunman:
- It's because she's a Level 0 that she’s immune to the paralyzing "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, 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.
- Despair Event Horizon: After she uses Level Upper and realizes she'll fall into a coma soon afterwards.
- Early-Bird Cameo/Continuity Cameo: Appears in both openings of the first season of Index, despite having never appeared in the novels.
- The Everyman: As above, Saten is a mere mortal amongst gods and angels, and the easiest character in the To Aru-verse to relate to, hence her surprising popularity.
- Fangirl: Of Teen Idol Hajime Hitotsui.
- Flower in Her Hair: A distinctive white-flower hairclip that is her signature accessory.
- The Gadfly: 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.
- Genki Girl: She tries to be one.
- Heroic Bystander:
- In Railgun Episode 1, she saves a little boy from being kidnapped by a bank robber who has powers. Then, in the finale she smashes the Power Nullifier Telestina is using to incapacitate Mikoto, saving the day.
- As of the premiere of Railgun S she may be heading for Chronic Hero Syndrome. As of the finale, she clearly is afflicted with it.
- I Just Want to Be Special: The poor girl just wants an ability, even if it's only Level 1.
- Laser-Guided Amnesia: Chapter 49 of the Manga.
- Locked Out of the Loop: Has no idea of the Sisters or Mikoto and Touma's adventures.
- Long Hair Is Feminine: The normal, down to earth girl of the quartet of heroines.
- My God, What Have I Done?: 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.
- Ms. Fanservice: The shower scene of the PSP game and the beach episode of Season 1 loves to remind us that anime Saten has the best proportions of the Railgun quartet.
- Muggle Best Friend: Mostly to Uiharu, but also to Kuruko and Mikoto, since she has no esper abilities herself, something she initially hates.
- Nice Girl: A romantic dreamer whose greatest joy in life is sharing happiness with her beloved friends.
- No Sense of Personal Space: Loves to flip Uiharu's skirt just to see her panties, especially if they're in public.
- Odd Friendship: She seemed to have developed this with Xochitl.
- Plucky Girl: Brave, optimistic and kind, nothing keeps this girl's spirits down for long!
- Rapunzel Hair: Not counting Kuroko (who has hers tied up in twin-tails as a rule), Saten's luscious long-black hair falls to her waist.
- Sailor Fuku: Her school uniform.
- Seiza Squirm: Does this during the festival episode during a tea ceremony.
- Shipper on Deck: 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.
- Shut Up, Hannibal!: Stops Telestina's gloating of humanity's supposed worthlessness by smashing the Capacity Down device paralyzing her esper friends with one mighty swing of her aluminum baseball bat.
- Stepford Smiler: In Academy City, life is hard for anyone who doesn't "measure up".
- This Looks Like a Job for Aquaman: The anime tries to invent things for her to do, such as being immune to Capacity Down when she actually shouldn't be.
- Too Dumb to Live: She was borderline during the the Railgun SS. 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 killed when Xochitl saved her at the last minute.
- You Leave Him Alone!: Shouts this to Therestina while smashing the Capacity Down device.
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).
Provides examples of:
- A-Cup Angst: When Kuroko comments that her body is "underdeveloped", she gets upset.
- Ascended Extra: Much like Saten, she's not really all that important outside the first story arc in the original manga. In the anime, her importance is significantly boosted.
- Badass Bookworm: 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 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.
- Cloudcuckoolander: She seems to edge into a state like this whenever she's in front of a computer.
- Cuteness Proximity: Around Misuko's pet boa constrictor Ekaterina. Amusingly, the snake scared everybody else.
- The Cutie: A small, cuddly and friendly breath of fresh air amongst her zanier friends.
- Did You Just Flip Off Cthulhu?/Defiant to the End: In Volume 15 of Index, she taunts the Level 5 Kakine Teitoku, even as he is torturing her, presumably in order to buy time to let Last Order escape. It would have ended very badly for Uiharu if not for Accelerator's subsequent Big Damn Heroes.
- Early-Bird Cameo: In both openings of the first season of Index.
- Flower in Her Hair: Whenever people ask about the flowers, she'll say she doesn't know what they are talking about. They are a headband of artificial flowers, and she wears it so often that she forgets about it.
- Fluffy Tamer: Everyone else took one giant step back upon meeting Mitsuko's snake, Ekaterina. Uiharu stayed behind to coo over it.
- Get A Hold Of Yourself Man: In Railgun Episode 23, she suffers a Heroic BSOD when 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...
- Ill Girl: In the manga, where she suffers from constant bouts of the flu.
- Kawaiiko: Small, cuddly, vulnerable and prone to being the brunt of Saten's off-colored sense of humor and Kuroko's short temper.
- Laser-Guided Amnesia: In Chapter 49 of the Manga.
- Little Miss Snarker: Towards Kuroko.
- Locked Out of the Loop: Has no idea of the Sisters or Mikoto and Touma's adventures.
- Mission Control: Often plays this role, usually with Kuroko on the other end.
- Nice Girl: A warm hearted, caring and responsible young lady, with an occsaionally cheeky sense of good natured humor.
- Non-Action Guy: As a trained member of Judgement, she should be an Action Girl 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.
- OOC Is Serious Business: Ruiko knows something is wrong when Uiharu doesn't react with embarassment to her skirt getting flipped up.
- Playful Hacker: She makes hacking into high-security government databases without superpowers look like child's-play, and with a relaxed smile at that!!
- Red Baron: Known as the "Goalkeeper" among hackers.
- Sailor Fuku: Her school uniform.
- Salt the Earth: 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 super computer 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 to 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.
- Selective Obliviousness: When she ran into Last Order, she did not notice her resemblance to Mikoto at all.
- Shipper on Deck: For Mikoto and Touma. When the two danced, she tried to stop Kuroko from interfering.
- The Smart Girl: 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.
- Sweet Tooth: Even more than the others, but circumstances often conspire to prevent her from actually eating them.
- Utility Magic: 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.
- What Kind of Lame Power Is Heart, Anyway?: 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.
