- Alternate Continuity: Has irreconcilable differences between how she is portrayed in the anime and in the manga. In both the manga and a cameo in the novels she is introduced as a New Transfer Student about a month after the events of the Railgun anime's first season, and quickly became good friends with Mikoto as well. The problem is that in the Railgun anime, she shows up in the very first episode, and has some important roles throughout the first season.
- Back-to-Back Badasses: With Kuroko in Railgun Episode 24.
- Big Damn Heroes: Twice, with Lampshade Hanging.
- Blow You Away: Her ability, Aero Hand, lets her generate gusts from her hands powerful enough to launch trucks as projectiles and knock over walls. She can also make a delayed wind attack to ambush enemies. At full power, she can launch things into outer space!
- Catch-Phrase"Do you, (person), know that you're (description) with Kongou Mitsuko of Tokidawai?"
"Do you persist in committing this outrage knowing that I am Tokidawai's Kongou Mitsuko?"
- There's also this variation:
- Drama Queen: When she's taken out during a dodgeball-esque event during the festival, she dramatically falls to the ground like she was dying, requesting that her attackers take care of her pet snake Ekaterina in her place. The referee immediately notes that those who have lost need to stand up and go to the defeated zone, causing her to sheepishly stand back up.
- Cuteness Proximity: She really likes children, and can barely contain herself around Febri.
- Feather Boa Constrictor: During the Beach Episode. It is her pet, Ekaterina.
- Friend to All Children: Much like Kuroko, though she's more open about it.
- Hidden Depths: Mikoto is surprised to find that Kongou was well aware that the girl participating in the tag competition wasn't actually Mikoto. Of course, Kongou assumed she was Mikoto's twin sister rather than her clone, but close enough. That's how 10032 is treated anyway.
- Jerk with a Heart of Gold: While arrogant, she honestly cares for her underclassmen and comes twice to the rescue of her self-proclaimed rival/friend Mikoto and is kind to children. And despite her arrogant attitude, she's also perfectly friendly to the victors after being taken out in one of the festival events.
- Kindhearted Cat Lover: She's badly injured by Baba Yoshio because after making it clear she'd kick his ass he targeted a nearby kitten instead. She tries to protect it and gets hospitalized as a result. Mikoto is not happy about this at all. She might well have hospitalized him or worse if she'd known he wasn't being mind controlled by Misaki.
- Large Ham: She loves theatrics and hamming it up as an arrogant and talented rich girl thanks to her father telling her people gather around a person of quality. He actually just meant that if she was a good person she would make lots of friends, but by then it was too late! A ham was born.
- Lovable Alpha Bitch: Kind of obnoxious and condescending, but she's actually very sweet. Howeer, she actually doesn't really have a high position at Tokiwadai. She might have been able to, but realized she didn't actually care about that kind of thing.
- Ms. Fanservice:
- Shameless Fanservice Girl: And she knows it; combining her generous proportions with heart-stoppingly erotic mastery of suggestive poses to make her one of the most popular models in Academy City.
- New Transfer Student: At least in the manga.
- Noblewoman's Laugh: She has one of these. Her variant however is not nearly as annoying as most examples of this trope.
- Normal Fish in a Tiny Pond: She transfers into Tokiwadai intending to take it by storm, but much to her dismay absolutely nobody cares. She actually just annoys people. If she had done any research, she'd have learned that you have to be at least level three to get in, there are two level fives and everyone else there is fairly rich as well. She doesn't stand out at all.
- No Sense of Direction: She gets lost twice in one day looking for her dorm.
- Ojou: The vocabulary she uses is extremely refined and genteel, even more-so than Kuroko's, as the thugs trying to mug her Episode 15 point out, annoyed by the noble arrogance it carried.
- One Woman Army: No matter how many opponents, she can mow them down with Aero Hand.
- Rich Bitch: Intentionally acted like this initially, because she misguidedly thought it would be the best way to get friends.
- Start My Own: Sometime after arriving as a transferee in Tokiwadai, she notes how there are several cliques/factions in the school. She couldn't decide which one to join, so she opts to start one of her own, but is discouraged after seeing the largest clique, led by the Queen of Tokiwadai. Then after failing to get anyone to join, when Wannai and Awatsuki offer to join her clique, she says they should be friends instead.
- The Rival: With Kuroko, whom she dislikes, and the feeling's mutual. However they come to grudgingly respect each other as warriors after fighting side-by-side in Railgun Episode 24.
- Uncle Pennybags: Though she is not shy about showing-off how wealthy and chic she is, she is equally generous about sharing all the perks and benefits of her wealth with her friends.
- Unknown Rival: She considers Mikoto her greatest rival to dominance in the school during the brief period she's trying to become someone important, but Mikoto never figures that out. She gives up right around the same time that she realizes her first friend in Tokiwadai was Mikoto all along.
Voiced by: Azumi Asakura (Japanese), Teri Rogers (English)The fifth Level 5 Esper. Being the second Level 5 to attend Tokiwadai, her followers and Misaka's followers often come into conflict. Her ability, Mental Out, involves the manipulation of memories and the human mind. She is also the leader of the largest clique in Tokiwadai.She first plays a major role in the Railgun Daihaseisai Arc, and is a bit of a Wild Card.
- Achilles' Heel:
- Her mental powers have no effect on animals and robots, so if she is attacked by them, she is extremely vulnerable.
- She actually has to aim at a person to use her mental powers on him, so if he is moving too fast, it would take considerable luck for Mental Out to work.
- A-Cup Angst: She was flat and ashamed of it when she was younger. One year later, she's grown much taller and filled out enough to look three to five years older than she actually is, much to Mikoto's despair.
- Agony Beam: Mikoto's electrical field prevents Misaki's mental powers from working on her. However, when Misaki tries, Mikoto gets a painful shock.
- Amplifier Artifact: "Exterior," which can boost her powers to beyond what even a level 5 should be capable of. It's a cloned portion of her own brain, enlarged to gargantuan proportions. It was originally intended to be able to give anyone her powers, but she didn't like that idea, so she stole it for her own use. In chapter 61 of the Railgun manga, Gensei Kihara hijacks it and uses it to force Mikoto to join with the MISAKA network and undergo the Level 6 Shift.
- Anchored Ship: Touma will never be able to remember who she is. This is different from the amnesia he got while saving Index in that it predates it and applies only to Misaki. Even after that event, he's met her several times, but always forgets her again afterward. She knows it's pointless to have any hopes for him, but if he ever does regain the ability to remember her she's still waiting.
- Animal Motifs: Her name contains the character for "bee". She sometimes calls herself Queen Bee and she is referred to as the bee in scientists' reports.
- Benevolent Boss: Her clique is completely loyal to her and willingly submit to her mind control and do not mind even her most disruptive demands. In return, she keeps them out of danger, places their safety above her own and doesn't control them without their consent.
- Bitch in Sheep's Clothing:
- In chapter 41, she shows up to threaten Mikoto through her friends, implying that she sees Mikoto making new friends as an attempt at forming a rival faction. Her next move is to use her power to confront Mikoto with the possibility of being zerg rushed by a mass of uninvolved students who would simultaneously be used as shields. Yep, she's a bitch alright.
- Might also be a subversion, as in a later novel she is shown to take good care of those she controls, even risking her life to fix the memory of an enemy. Her threatening moves against Mikoto in the beginning might be caused by the fact that she didn't trust Mikoto that much at the time. In later novels her interactions with Mikoto is shown to be better and revolve around teasing her.
- Chekhov's Gunman:
- She was first mentioned in the first volume of Index as someone who might have been able to fix Index's memory loss.
- Mikoto considered asking her to fix Touma's memory loss, but changed her mind, not wanting to be in her debt, in addition to being unable to trust her.
- She shows up briefly in the last episode of Railgun S. Mikoto swallowed her pride and asked her to edit a few memories so that Shinobu, Janie, and Febri could live in peace.
- Chekhov's Skill: Chronologically, the first trick we see her perform with her ability is switching someone's perceptions; she demonstrated the ability to make a test subject think the apples (which he hates) he was eating were actually watermelon slices. Soon after, the researchers ask her to use this trick to pretend to be Dolly's friend. And then it turns out she was using this trick on the researchers the entire time, sitting in on their meetings after she had their helmets sabotaged.
- Crippling Overspecialization: All espers with mind control powers are apparently really lazy and out of shape because of how incredibly useful their ability is. Block her mind control and the best she can do is throwing her remotes at you. She doesn't even have good aim.
- Curtains Match the Window: Her hair and eyes are both gold.
- A Day in the Limelight: Volume 11 of NT is from her perspective. Accelerator and Shiage don't appear at all, Mikoto is only mentioned in passing and Touma is only present in flashbacks and at the very end. We finally learn why she trusted him so quickly a few volumes before and in Railgun, something very unusual for her given her paranoia.
- Everyone Calls Him "Barkeep": She is usually referred to as the "Queen of Tokiwadai" rather than her actual name.
- Everyone Has Standards: She knows she's a jerk, but she won't abuse the power over people who have willingly become her pawns, she tries to keep mental damage to targets to a minimum and she refuses to read Touma's mind.
- The Faceless: Despite first being mentioned in the very first volume of Index, she never makes an official appearance until chapter 41 of Railgun, where she shows herself to Mikoto. Justified, as she apparently uses her power to communicate through others.
- The Fake Cutie: She has rather cheerful and goofy mannerisms that cover up a paranoid and manipulative mind. Of course, she's not actually trying to fool anyway, she just seems to find it fun to piss people off with her artificial cutesy attitude.
- Fandom Rivalry: An in-universe example of it.
- Fatal Flaw: Paranoia. She refuses to trust people she can't mind read, which causes problems with Mikoto. Even when the two have the same goals, Misaki does everything she can to sideline her until absolutely forced to work together. Touma is the exception to this rule. Due to his Imagine Breaker, she obviously can't mind read him, but doesn't seem to care. In fact, he may be the only person she truly trusts.
- Friendly Rivalry: Mikoto doesn't like her and beneath her cheerful attitude Misaki doesn't care for her either. However, they're quite capable of cooperating and they don't hate each other nearly as much as Misaki and Seria do. There's no real malice behind it and they reached an understanding while saving Misaka 10032.
- Good All Along: Putting aside her introduction, she is a good person who despite possessing Mind Control Power, operate under personal rule of "always taking a good care of those who she control". This even apply to her enemy.
- Good Is Not Nice: Despite first appearances, during the arc of the Railgun manga where 10032 gets kidnapped, she is not the villain. She kidnapped 10032 to keep her out of the bad guy's hands, and to heal some damage done to her. This doesn't make her a good person, just not evil.
- Hypocritical Humor: When Mikoto calls her out of shape, she says only someone with the mind and body of a child would be so petty about mere physical ability. Mikoto makes fun of her Wingding Eyes by asking if she's from a shoujo manga and an offended Misaki retorts that insulting someone's body is just low.
- I Am Not Left-Handed: The researchers studying her ability used complicated technological helmets to block her powers. She suborned one of the low-level techs, had the helmets sabotaged, and was able to subtly take control of the entire operation without anyone noticing.
- I Got Bigger: Inverted, as New Testament Volume 11 reveals that in the previous August (a year before the events of Index/Railgun) Shokuhou had no bustline to speak of, and only a mere 148 centimeters tall.
- I Want My Beloved to Be Happy: She fell in love with Touma during an incident which ended up erasing his memory of her permanently but stays out of his life to avoid troubling him.
- I Will Wait for You:Misaki: "If... If someday you do manage to overturn the expectations created by the adults and you remember me... Then let's have an important talk. A very, very sweet, kind, and important talk."
- I Work Alone
- In the Railgun manga, she says trust and co-operation are unreliable, and she won't work with anybody whose minds she hasn't read. She eventually seeks out Mikoto for help simply because she's forced to admit that she won't be able to save the Sisters otherwise and the memory of her friendship with Dolly is one of the few redeeming characteristics about her.
- The sole exception so far is Touma, due to her feelings for him, despite that her powers obviously won't work on him.
- Jerkass: Despite working alongside Misaka she isn't exactly the nicest person. However, she does have standards: She's quite protective her minions and were she to commit a crime with a pawn or lead them to be injured, she would take full responsibility for it.
- Jerkass Has a Point: When Misaki bluntly states that she has no intention of trusting people whose mind she cannot read, Mikoto is horrified at her paranoia. But as Misaki points out, why would you trust someone in Academy City? Trusting people got ten thousand clones murdered just because a little girl wanted to help cure muscular dystrophy.
- Kick the Dog:
- When one of the members of her clique tries to prevent Misaki from consuming more sweets (out of concern for Misaki's 'wonderful proportions'), Misaki mind controls her and the rest of the clique, telling them to 'challenge yourselves to eat 15 eclair as fast as possible.'
- Deleting Kuroko, Uiharu and Saten's memories of Mikoto seemingly out of nowhere. Yes, she had a reason, but she couldn't have at least considered a better option? And it turned out to be unnecessary in the end anyway.
- Her reaction to Kongou getting rather brutally injured by Baba Yoshio. She basically says it's a shame that Kongou was hurt, but it helped her anyway since she had no way to deal with Yoshio's Killer Robot mooks.
- Locked Out of the Loop: Does not like this at all. However, both times she tried to get Touma to tell her what's really going on, she gets interrupted by outside forces.
- Magic Feather: She carries various remotes in her purse. While she doesn't necessarily need them to use her power, the potential range and usage of her power is simply too complex for her to control correctly and thus she uses her remotes as a focus on what she wants to do. The remotes don't really do anything.
- Meaningful Name: Her first name can be translated as "Wish For Control". Her full name can be translated as "Dominated Psychology".
- Memory Gambit: Finally defeats Gensei Kihara by using her powers on herself so that she'd think the limiter release code and self-destruct code for Exterior were switched. Gensei entered the self-destruct code by mistake, never suspecting a thing until it was too late because she sincerely believed it was the limiter release code.
- Morality Pet: Touma and Dolly are the easiest ways of bringing out her good side. The latter is dead, but Misaki values her memory greatly.
- No Good Deed Goes Unpunished: She saved Touma's life by using her powers, but in the process damaged his brain so that he will never be able to remember her face.
- Ojou: According to Mikoto, she's the most Ojou of all the Ojous at Tokiwadai, which really says something. She, however, subverts the traditional archetype by being quite frivolous, making silly poses, not caring for her weight, and saying cliché anime lines. It's just that she erases certain people's memories and that her fangirls don't say anything about it.
- Only Friend: Dolly is implied to be one of the few people she ever cared for.
- Power Incontinence: She uses a series of remotes to help control her power. There are just so many applications that it's hard (but not impossible) for her to focus on the specific thing she wants. The remotes simply help her concentrate.
- Properly Paranoid: After what happened to Mikoto, Accelerator, and especially Touma, can you blame her? In New Testament Volume 7, her paranoia allowed her to correctly guess that Tsuchimikado sent Touma on a wild goose chase in order to get him out of the way so he wouldn't interfere with whatever he's doing.
- Secret Keeper: It's heavily hinted that she not only knew Touma prior to his memory loss (and is thus aware that he has amnesia), but also knows about Imagine Breaker.
- It's revealed that the memory loss Misaki refers to upon meeting Touma is actually a separate instance.
- Sitcom Arch Enemy: She does not get along with Seria Kumokawa.
- Squishy Wizard: Given that her powers deal with the mind, and that she skipped P.E. and does not exercise regularly, she is a skinny, out-of-shape girl. In chapter 56 of Railgun, she's panting and ready to collapse from trying to follow a lightly-jogging Mikoto.
- Super Drowning Skills: In addition to not exercising, she never bothered to learn how to swim. She once almost drowned after falling into a shallow pool until she was told by Touma to Stop Drowning and Stand Up.
- The Rival: To Mikoto, who is the other level 5 at Tokiwadai.
- Though part of the reason she resents Mikoto is because Her relationship with Touma is similar to how her's was before Touma lost his memories protecting her.
- Also to Seria Kumokawa. Both are regarded by people as high-class beauties. Both are experts at manipulating the mind, Misaki via her power, and Seria via pure manipulation and guile. Both are extremely wary of one another, keeping tabs on one another (Misaki via mind controlled 3rd parties, and Seria via surveillance technologies) leading to a sort of cold war between the two, with the knowledge that should conflict break out between the two, it would only lead to a mutually assured destruction. The ONLY time the two can ever put things aside and work together is if it concerns Touma, because both of them love him and doesn't want the other to get a head start on the other.
- Story-Breaker Power: She loves Touma, is a decent enough person in her own way, seems to have a lot of free time and is at least in contact with Mikoto on a fairly regular basis. However, her powers give her complete, instant and unresistable control over anyone she targets, so long as they aren't moving too quickly for her to hit, an electromaster or mind control esper or wearing very specialized gear. She could, in theory, defeat the likes of Fiamma in a straight confrontation unless he killed her immediately. See the problem? Not only is this too strong of an ability for an ally, but it's really too powerful even for an enemy to have, so her power can't be replicated with a machine like Mikoto.
- The Tease: Absolutely willing to help with Touma and trusts him completely, but she also likes screwing with his head by flirting with him through a puppet and making the poor girl do highly embarrassing things. He can't even apologize.Touma: Why are you increasing my supposed list of crimes!?
- Telepathy: Academy City's most powerful telepath. However, it only works on people, not animals or robots.
- Unwitting Pawn: All her actions in the Daihaseisai arc in the Railgun manga play straight into Gensei Kihara's plan.
- Verbal Tic: Uses "power" and "ability" as suffixes a lot.
- Voice for the Voiceless: She often uses mind-controlled proxies and her own followers whenever she needs to communicate.
- Wild Card: She's a level five with zero confidants and rarely appears in public without an escort of minions, occasionally refusing to appear directly at all. She knows a fair amount about the city, the dark side and even Imagine Breaker, but she tells no one anything and rarely moves except to defend her own position. She does have a soft spot for Touma and the Sisters, but she doesn't like Mikoto and hates Kumokawa Seria.
- Wingding Eyes: She has stars in her eyes. According to her she was born like this. Additionally the same stars appear in the eyes of those who she is controlling.
- Younger Than They Look: She's a middle-schooler, but she could pass for eighteen or nineteen easily. She actually developed very quickly: A mere year ago she basically looked like a blonde Kuroko.
- Zettai Ryouiki: With lace.
- Voiced by: Minami Tsuda (Japanese)
- Anime Hair: She's most commonly referred to as the ringlets curl girl thanks to her rather improbable hair.
- Ascended Extra: She's a main character in the spinoff A Certain Scientific Railgun: Astral Buddy.
- Birds of a Feather: She gets along surprisingly well with Mikoto. The pair bond over their mutual age inappropriate love of Gekota.
- Entendre Failure: When Aogami Pierce is selling risque dreams of Mikoto and Misaki while within hearing range of the two and Junko, the level fives get increasingly angry while the entire lewd rant flies completely over her head.
- Happiness in Slavery: Her idea of a perfect dream and way to bond with Mikoto is a two part dream. The first part is about Gekota, so well done there. The second part is making the dreamer work as Misaki's slave. Mikoto wakes up the next morning horrified but unable to actually be angry since she meant entirely well.
- Nice Girl: She's very friendly and well meaning and manages to be friends with both Mikoto and Misaki. Unfortunately, she lacks the aggressive edge of either of them and is intimidated by both when they get angry, despite being older.
- No Name Given: She's never given any sort of name until she gets her own spinoff. Mikoto might not even know her name in the first place.
- Oblivious to Love: In the first chapter of her spinoff series, she completely fails to understand that one of her classmates is in love with her until Kuroko explains it to her, which results in Junko becoming a blushing mess.
- Odd Friendship: During the Level Six Mikoto project she's tasked by Misaki with stalling Mikoto and does a rather good job simply by talking about shared interests. Afterwards they're shown talking again, meaning Junko really did want to be friends.
- Princess Curls: Rich girl, rich hair.
- Strange Minds Think Alike: When she and Mikoto are fangirling over Gekota the other members of Misaki's clique stand in the background completely unable to relate to any of their logic or statements, seemingly embarrassed on Junko's behalf.
The Dormitory Supervisor
Tokiwadai Dormitory Supervisor
Neck Snap) troublemakers are... effective. She can and she will find out which rules were broken, and she will always be there to administer her brand of discipline.
- Amusing Injuries: She gives people unfortunate enough to cross her the pleasure of having their necks broken and still live to tell the tale.
- Badass Normal: When even Level 5s cringe at the mere mention of her name, you know she always means business. On an omake segment, she was even shown taking down a group of Hound Dog commandos virtually unarmed, and in one incident scares even the normally energetic Gunha into running away.
- Blatant Lies: When speaking to her crush, who runs an orphanage.Supervisor: I've never scolded my dormitory students.
- Cannot Spit It Out: She developed a crush on her coworker Daigo, and often blushed and stammered in his presence. Kuroko and her friends encouraged her to ask him out, but he turned out to already have a girlfriend.
- Christmas Cake: Lampshaded by Kuroko with delightful viciousness.Kuroko: Oh, I understand your anxiousness, esteemed Dorm Mother. To be in the latter half of your twenty-ninth year, the twilight of your eligibility for marriage, must be so unimaginably frustrating...
- Death Glare: Her default expression, which terrifies everybody.
- The Dreaded: To the girls of Tokiwadai.
- Hidden Heart of Gold: She tries her very best to hide the fact that she’s a kind, gentle, and loving teacher at a kindergarten full of orphans when not administering her brand of discipline at the Dormitory.
- I Want My Beloved to Be Happy: After Daigo revealed he already had a girlfriend, she was clearly crying inside, but smiled and congratulated the couple.
- Knight Templar: When it comes to dorm rules.Supervisor: Oh I see. "Extenuating circumstances", you say? However... [grabs Kuroko, breaks her neck, and tosses her aside like a ragdoll] were I to accept that as an excuse, I would not be able to maintain the peace of this dormitory. Those who break the rules ought to be punished. Don't you agree, Misaka?
- Neck Snap: It's what she does.
- No Name Given: No one refers to her by her name, not even her coworkers.
- Oh, Crap!: Has elicited some epic ones from Mikoto◊ and Kuroko◊.

- She Cleans Up Nicely: Watch her all dolled up near the end of Railgun episode 18.
Kinuho Wannai and Maaya Awatsuki
Kinuho Wannai and Maaya Awatsuki
Kinuho (right) is voiced by: Haruka Tomatsu (Japanese) and Kristi Kang (English)Neither of them play a very prominent role in the series. Kinuho's ability is Hydro Hand (water manipulation), while Maaya's is Float Dial (buoyancy manipulation).
- Big Damn Heroes:
- In the Railgun manga, they show up just in time to save Kongou and Saten from Baba Yoshio.
- They also help out in the last episode of Railgun S, along with all of Judgment.
- The Dividual: They almost always appear together, and apart from their appearance and their abilities, they have very little differentiating them.
- "Do It Yourself" Theme Tune: Maaya's Japanese voice actor is also the vocalist of fripSide, who performs all opening theme songs of Railgun.
- Gravity Master: Maaya's buoyancy ability basically works like this.
- Heart Is an Awesome Power: Maaya's ability to manipulate the buoyancy force doesn't seem too useful in combat at first, but it allows her to alter projectile motion, to make leaps In a Single Bound, to Walk on Water, and to make heavy objects lighter. She can even turn off buoyancy in a given area so that nothing can fly.
- I Am Not Left-Handed: Kinuho pulls this off magnificently against Baba Yoshio. She can manipulate four clumps of water, but only used three until the right moment to catch Baba off guard proving she is not as naive as she seems.
- Is This What Anger Feels Like?: Kinuho mentions in Railgun Chapter 45 that she's never really gotten angry before and Maaya's attempt at getting angry was cute instead, but seeing Kongou getting beat up and her beliefs insulted in Chapter 50 seems to have finally gotten both of them quite angry.
- Let's Get Dangerous!: Against Baba Yoshi.
- Let Us Never Speak of This Again: They have this reaction when they return to help clean the pool in episode 2 and find Mikoto trying to fend off Kuroko who's under the influence of her own Love Potion.
- Making a Splash: Kinuho can control up to four clumps of water at a time, but she's not skilled enough to control water that has been scattered on the ground.
- Mundane Utility: They offer to use their powers to help Mikoto and Kuroko clean the pool in episode 2. Its also suggested they may use their powers to help them get better times in swimming club.
Voiced by: Nozomi MasuA Level 3 first year student of Tokiwadai who appears exclusively in the Radio Drama. She is obsessed with Mikoto and eventually challenged her to a fight, believing that if she won, then Mikoto would fall in love with her (she had heard a rumor that Mikoto was attracted to people who were stronger than her, based on Mikoto constantly challenging Touma to fights). Mikoto defeated her due to unexpected outside interference and sent her off, annoyed that she found someone just like Kuroko.
- Deer in the Headlights: She froze when a billboard broke and starting falling toward her. Mikoto had to save her.
- Didn't See That Coming: She almost defeated Mikoto, only for a stray blast from a magician Touma had been fighting somewhere else in the city to almost hit her. This scared her out of her wits and gave Mikoto enough time to recover.
- Man of Kryptonite: Her main ability is to emit a field that prevents electricity other than natural bio-electricity from flowing. Thus, she negated Mikoto's powers and was able to corner her. Mikoto eventually managed to generate enough electricity to overpower the field.
- Mind over Matter: A minor component of her ability is telekinesis. She can only lift and throw relatively light objects like chairs.
- Schoolgirl Lesbians: In love with her classmate Mikoto.
- Stalker With a Crush: For Mikoto.
- Too Kinky to Torture: After her defeat, she enjoys getting shocked by Mikoto, who gets annoyed that she reacts like Kuroko does to her punishments.
Touma's High School (unnamed)
One of the Seven Wonders of a Certain High School
The White Smoker
- A-Cup Angst: Gets upset when she loans Index her pajamas, and the latter complains that the chest area is too small for her (herself also suffering from this trope).
- Beware the Nice Ones: In New Testament Volume 9's World Alpha, she stabs Touma with a knife.
- Cat Smile: In the comfort of a hot bath.
- Chekhov's Skill: The healing spell Index taught her early on comes in handy when Aisa is nearly killed by Oriana.
- Clock King: Mild example. She can accurately tell the exact time and date in any circumstance without having to look at a clock.
- Color Failure: An epic one.◊
- Cool Bike: She bought the Acro Bike in Volume 13 of the New Testament series, a bike designed to allow riders to backflip, ride up stairs, along walls, along ceilings, and even fly up to 30 m through the air! It's awfully handy when Touma and Mikoto are running away from the High Priest, a universe destroying Magic God.
- Cool Teacher: All of her students love and respect her for her personality, looks, and wisdom.
- Hard-Drinking Party Girl: A chain smoking alcoholic young girl...
- Hot for Student: Towards her "Kamijou-chan".
- Improbable Age: In-Universe — legal in age but lusted over by her Lolicon-inclined detention students.
- Kawaiiko: Her students just can't get over how cute she is.
- Locked Out of the Loop: Despite having been taught a healing spell by Index, she is unaware of the Magic Side and whenever Touma comes back from having saved the world, she scolds him for skipping school.
- Mama Bear: During the Daihasei school festival, she defended her students against a teacher who insulted them during the Daihasei sports festival. Hearing her defense actually inspired the students to do their best to prove her right.
- Meaningful Name: "Komoe" is a combination of "ko" (small) and "moe" (Moe).
- The Mind Is a Plaything of the Body: Hard-Drinking Party Girl and chain-smoking aside, she tends to act in a childish manner towards her students, including having a childlike crush on Touma, in spite of being one of the older Academy City personnel, partly because she has what is essentially a body of a little girl.
- Nice GirlKomoe: I got a lot of students. Some are nice, some are naughty, and some even blow big holes in my roof. But I love them all!
- Older Than She Looks:
- And exactly why she still looks like a kid is a mystery for the ages. When Accelerator and Last Order first meet her they immediately assume that she was involved in anti-aging experiments, which she emphatically denies.
- In New Testament Volume 6, Mikoto refuses to believe her when she says she is a teacher, assuming she is just a kid playing pretend.
- One of the Kids: In mentality and appearance.
- Precocious Crush: Inverted. She is a teacher and has a crush on Touma, a student, though she has the body of one who would have this type of crush and her crush is pretty much this played straight, just with the roles reversed.
- Sensei-chan: She is, after all, a teacher that looks like a child.
- Team Mom: Appearance aside, she's the closest thing to a mother figure the children of the cast have, and a strong and nurturing one at that too.
- The Unreveal: She drives a normal-sized car. When Touma gets confused at how she is able to drive it when her legs are too short to reach the pedals, she just snaps at him for doubting her ability instead of explaining how.

I think I need to visit the next shop over...
Ringlet Curl Girl: It looks like she's going to kill them! Queen, you have to stop—
Misaki: Today, I'll do you the favor of altering the witnesses' memories. You handle the security cameras.

- Locked Out of the Loop: The only recurring character of the series who is not directly or even indirectly involved in any of the major events.

- Everyone Calls Him "Barkeep": Credited as this name, we have no idea what his real name is.

- Otaku: Taken Up to Eleven. See his rant above.

Japanese Christian with a Miko attire formerly from Kirigaoka Girls' Academy. She possesses the ability to kill vampires with her blood, which also attracts them.

- Demoted to Extra: Even though she "lived with Touma" before moving to Komoe's apartment, her participation in the narrative becomes virtually non-existent past Episode 15, as cheekily pointed out in the DVD extras.Aisa: I'm ignored... therefore I a— [cuts to next scene before she could finish her sentence]
- Hime Cut: A classic example of the "straight bangs and long hair down the back" and wears miko attire, but she insists that she's a magician/esper instead. For bonus points, if written with different characters her surname can be read as "Princess Hair."
- I Just Want to Be Special: She seems to have an inferiority complex, and wants to stand out. Aureolus Izzard taught her a little about magic, and she regrets not being able to use it due to being an esper. After all, her esper power is useless in a fight.

Voiced by: Ayumi Fujimura (Japanese), Skyler McIntosh (English)A member of Touma's class. She's very responsible, health-conscious and clean. Basically everything Touma is not. Is the only girl not to fall for Touma's "charms"... except it's implied she might have already.
- Accidental Pervert: Once walked in on Touma when he was changing.
- Adaptational Attractiveness: In the novels she is described as a "pleasant looking girl without a shred of feminine sex appeal". In the anime, on the other hand, she is quite a beauty, with a bust that could give Kaori a run for her money.
- Almost Kiss: With Touma.

- Forehead of Doom: Her "Forehead Deluxe".

- Tsundere: Towards Touma.
A mysterious sempai in Touma's school, Seria has connections to one of the Board of Directors for the whole of Academy City. Both her motives, and the extent of her knowledge is unknown, but she seems to love the carefree life of a high school student. May or may not be in love with Touma.
- A Day in the Limelight: One of the short stories from one of Kiyotaka Haimura's art books, where she uses a love letter to Touma to catch a spy.
- Angst Coma: While not literally in coma, she became extremely lethargic and refused to work, just staring blankly, after Touma's "death".
- Awesomeness by Analysis: Her fighting style. This includes being able to dodge gunfire while walking at a leisurely pace by reading the angle of the gun.
- Battle of Wits: Kaziumi points out that these are fights that even Touma can't fight. Which is why Touma can do a lot of things they can't.
- Becoming the Mask: She chose to live a school life, as Touma's senpai, along with her Board work. She liked it.

- Master of Your Domain: Can use autohypnosis to block out pain from injuries including having an eye removed.
- Out-of-Character Moment: Her calling Touma in to save her during New Testament 7 while under the effects of Agitate Halation.
- The Rival: To Misaki Shokuhou. Both are regarded by people as high-class beauties. Both are experts at manipulating the mind, Misaki via her power, and Seria via pure manipulation and guile. Both are extremely wary of one another, keeping tabs on one another (Misaki via mind controlled 3rd parties, and Seria via surveillance technologies) leading to a sort of cold war between the two, with the knowledge of both sides that should conflict break out between the two, it would only lead to a mutually assured destruction. The ONLY time the two can even put things aside and work together is if it concerns Touma, because both of them love him and doesn't want the other to get a head start on the other.
- Secret Keeper: She's one of the few people who knows about Touma's memory loss.
- Sempai/Kohai: Sempai to Touma. A role she quite enjoys.
- Smug Snake: Though not a bad guy. Probably.

She wouldn't care or anything, but says Touma wouldn't be able to handle it if she died. Now, here's where the subversion comes in: She absolutely means it. She doesn't care much about Misaki, but knows that Touma failed to save another girl once and it apparently left him absolutely broken up inside, though he managed to hide it from Misaki at the time. Seria doesn't want him to have to go through that again.
Sakugawa Middle School

- Chekhov's Gunman: Appears three episodes before she has any bearing on the plot.
- Cloudcuckoolander: Has a tendency to suddenly space out. Her comatose friend telepathically contacting her was the cause of some of this, but not all.
- Parental Abandonment: She's a Child Error, meaning she was dumped in Academy City by parents who then failed to pay her tuition or retrieve her.
- Red Herring: She's unable to cause the Poltergeist incidents on her own.
- Telepathy: A weaker version, in that she's primarily a receiver, and can't really do anything useful on her own. At least, not under normal circumstances.
- Chekhov's Gunman: First appears in Kiyama Harumi's flashbacks.
- Chekhov M.I.A.: Due to her (and the other Child Errors) attempting to wake up from being comatose, the Poltergeists occur in the city.
- Comatose Canary: Due to her ability, she was crying out to Erii every time Kiyama tried to wake her from her coma.
- Expy: Possibly one of Ritsu Tainaka. They not only look alike, they even have the same voice actress!
- Telepathy: Like Erii, she's pretty weak, and can usually only communicate with specific people.
- Innocently Insensitive: He broke the Tokiwadai Dorm Supervisor's heart and didn't even notice.
- Likes Older Women: His girlfriend and later fiance Kazuko Shigenomori is much older than him. He also had a positive reaction to seeing the Tokiwadai Dorm Supervisor all dressed up.
- Oblivious to Love: He did not pick up on the Tokiwadai Dorm Supervisor's very obvious crush on him, though this may be because he had been seeing Kazuko the whole time.
- Official Couple: With Kazuko. He eventually proposes to her.

Kirigaoka Girls' Academy
- Adjusting Your Glasses: Does this a lot.

Mikoto stops him from killing himself, saying he has to face justice for his actions, then the heroes stop the missile. He and his cohorts are arrested.
- Big Bad Wannabe: He sees himself and his group as one of the most powerful factions in Academy City, who will revolutionize the world with their technology. They...are not. His master plan involves five researchers using an Artificial Human and a whole lot of robots. The arc immediately preceding his involved countless researchers using twenty thousand Artificial Humans note and enough money to bankrupt a nation, and was just a mid-level plan in Aleister's ongoing one-man Gambit Pileup. No wonder Gensei Kihara referred to the whole thing as "summer arts and crafts."
- Fantastic Racism: Hates espers. See Recognition Failure.Haruki: Those who rely on their powers are powerless!
- Far-East Asian Terrorists: Is one with STUDY near the end of Railgun S when he attempts to attack Academy City with a live missile.

- Jerkass: After Mitsuko Kongou flawlessly took down a purse snatcher, he comes out and causes the cheering crowd to turn against her, using the Probability Fallacy to imply she could have killed or severely injured a bystander if luck was not on her side. As Mitsuko sinks into self-doubt, he walks away and smirks.
- Mad Scientist: Sends robots to attack espers and gather data on them, referring to the fights as experiments.
- Meaningful Name: His first name means "springtime tree" and his last name means "having an abundance of something".
- Never Be a Hero: Criticizes espers who fight crime, arguing that they just throw their powers around to show off and could hurt someone in the crossfire.
- Recognition Failure: He's won several awards in national science competitions, but hardly anybody knows who he is because espers overshadow regular people in terms of fame. This is one reason why he hates espers.
- Smug Snake: He's very intelligent, but he overestimates himself and his robots and underestimates his foes. He manipulated the legal system to take out Anti-Skill, but did not expect Judgment to step in. He screwed with Shizuri Mugino, and did not expect her to show up seeking revenge.
- Start of Darkness: He was once an idealistic young researcher, until he learned how much discrimination non-espers face in Academy City. The final straw was when he overheard his idol, Gensei Kihara, whom he thought understood him, badmouthing him for his anti-esper ideals.
- Underestimating Badassery:
- He vastly underestimates level 5's in general, and Mikoto specifically. He thinks that the trouble she had with his non-electrical robot meant it was too strong for her, when in reality she was holding back because she thought it had a person inside.
- In episode 23, he has Mikoto injected with a paralytic that cuts off her nerve functions below the neck, and doesn't even bother guarding her, since it will be in effect for hours. But she's an electromaster, so she just uses her powers to take manual control of her body.
- Villain with Good Publicity: Is extremely charismatic, to the point that he can criticize someone who just saved the day and get the crowd on his side.
- Would Hit a Girl/Would Hurt a Child: Doesn't care who his experiments hurt. Later, he beats up Shinobu Nunotaba and gives her a black eye.
- Because You Were Nice to Me: She starts courting Saten after Saten mentions that her eyebrows are "unique" rather than ugly.
- Big Ol' Eyebrows: She is very ashamed of them. Her ex-boyfriend said they were ugly when he dumped her. However, Saten finds them quite cute, calling them her "charm point."
- Bi the Way: She used to have a boyfriend. Now she has an obvious crush on Saten.
- Cannot Spit It Out: Does a lot of blushing and stammering around Saten.
- Disproportionate Retribution: A Tokiwadai student stole her boyfriend, so in response, she regularly ambushed Tokiwadai students, knocked them unconscious with a stun gun, and drew Big Ol' Eyebrows on them.
- Face Doodling: See Disproportionate Retribution.
- Failed a Spot Check: Inflicts it on other people. Dummy Check makes it very difficult for people to notice her. It doesn't work against mechanical surveillance, and her reflection still appears in mirrors.
- Heel–Face Turn: After Saten decides to befriend her. They become regular pen-pals during her prison sentence and consistently after.
- Laser-Guided Amnesia: When Dummy Check was enhanced by Level Upper, this allowed her to erase the short-term memories of anybody who manages to notice her.
- Odango Hair: As seen in the picture.

- Shrinking Violet: Before she was powered up by Level Upper.
- Stealth Expert: Thanks to Dummy Check.
- Disproportionate Retribution/Roaring Rampage of Revenge: He hated everyone, especially Judgment, because seemingly nobody helped him when he was bullied. He then tried to blow everybody up.
- Far-East Asian Terrorists: Of the anti-Judgment variety since they didn't do anything to take down bullies.
- Headphones Equal Isolation: Before his official debut, he is often shown in the background wandering aimlessly while listening to earphones. It turns out he was taking Level Upper at this time.
- I Just Want to Be Special: He wanted power, both to get revenge on his bullies and because he was jealous of people with powers.
- Mad Bomber/Stuff Blowing Up: Synchrotron allows him to accelerate gravitons (the particle that mediates the force of gravitation) in aluminum until it explodes. The larger the piece of aluminum, the more powerful the explosion.
- Squishy Wizard: For all the power he gained, he's still a wimpy geek. To prove a point, Mikoto takes him down with a single, non-electrified punch.
- Ungrateful Bastard: Mikoto saved him from some bullies once, but he rudely brushed her off, asking why she didn't save him sooner.
- Truth in Television, those who are bullied tend to be jaded and cynical about help once they actually get it.
- Villainous Breakdown: He loses it when Touma blocks the aluminum bomb he put in a child's toy, meaning he failed to kill anyone.
- Would Hit a Girl/Would Hurt a Child: During his rampage, he would sneak aluminum everywhere and then detonate them. He was fond of putting the aluminum in children's toys and distributing the toys.
A young boy from Matsuume Elementary School introduced in the Dream Ranker arc of the Railgun manga. His unnamed esper ability grants him limited precognition, but unfortunately the only things he can see are horrible accidents.
- All of the Other Reindeer: Shaie’s power caused him to be bullied and picked on at school, as the other children believed he was causing the accidents rather than simply predicting them.
- Blessed with Suck: Precognition isn’t so cool when the only thing you can see are other people getting hurt.
- Cassandra Did It: See above.
- Heroic R.R.O.D.: Use of his power causes Shaie severe stress and results in anemia and nosebleeds. Extensive use can even leave him bedridden.
- Intergenerational Friendship: With Kuroko.
- Magical Camera: Shaie can’t show other people his predictions without focusing his power through a camera. The resulting photograph, when read by a special machine, produces a blurry image of the scene of the accident.
- You Can't Fight Fate: It’s not possible to prevent the accidents Shaie predicts by normal means. Trying to do so usually only results in the victim getting hurt somewhere else. This was one of the reasons he uploaded his photographs to the Treasure Hunter App, in the hopes that someone could figure out a way to stop them. Ultimately subverted when it turns out that teleporting the victim away can break the scenario.
