Tokiwadai Middle School
In General
Tokiwadai Middle School is an all girls school within Academy City and one of it most prestigious. It has a strict bar for entry that ensures it hosts a small but powerful student population of espers of influential background.
Tokiwadai is also where half of the main Railgun cast currently attend, namely Mikoto and Kuroko, and where they often encounter their fair share of friends, enemies, and trouble.
- Absurdly Divided School: A variety of factions exist within Tokiwadai with Misaki's faction, unsurprisingly, being the biggest of them all, and her faction has factions of its own. Unlike most examples, the cliques are less like warring factions and more like clubs and research societies for interested and like-minded students. The relationship between cliques were much more tense during Mikoto and Misaki's first year at Tokiwadai, but Misaki is implied to have put an end to all the petty conflict thanks her schemes.
- Boarding School: The school has dorms and other facilities of daily living for their students.
- Everyone Has Standards:
- One of their known prerequisites is that a potential student must be a Level 3 esper. This rule is so strict that the school once sparked an international incident for refusing to accept a girl from a royal family because she didn't the power level requirement. This shows that despite being a school whose student population is primarily made of The Ojou, no amount of money can ever change or bend their rules of admission.
- However, while money can't make the school admit you as a student, a student's skills potentially could. This was the case for Arei Houjou, as despite being formally classified as a Level 2 esper, her skills at understanding and using her power meant she was effectively Level 3.
- Ojou: Most of the student body are made up of girls from famous and rich families who could even afford the tuition in the first place.
- Superhero School: Downplayed as none of the students are expected to perform super heroics or similar acts, nor does the school's curriculum primarily revolve around their powers. Regardless, the entire student body is made of Level 3 or above espers, which means the students all have stable and considerable abilities which the school is equipped to train and test on a fairly regular basis.
Mikoto Misaka
Mikoto Misaka
Kuroko Shirai
Kuroko Shirai
Mitsuko Kongou
Mitsuko Kongou
Voiced by: Minako Kotobuki (Japanese) and Jamie Marchi (English)
A Level 4 and 2nd-year transfer student of Tokiwadai Middle School. A rival to Kuroko Shirai, she is confident, boastful, and desires to become a Level 5. Although she often brags about her abilities, she usually finds herself the victim of several attacks.
- 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 create ejection points on anything she touches, which will create gusts of wind powerful enough to launch trucks as projectiles and knock over walls. She can delay the ejection of wind to ambush enemies. At full power, she can launch things into outer space!
- Character Catch Phrase:"Do you, (person), know that you're (description) with Kongou Mitsuko of Tokidawai?"
- There's also this variation:
"Do you persist in committing this outrage knowing that I am Tokidawai's Kongou Mitsuko?" - Cuteness Proximity: She really likes children, and can barely contain herself around Febri.
- 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.
- Feather Boa Constrictor: During the Beach Episode. It is her pet, Ekaterina.
- Fire-Forged Friends: She's become friends with Mikoto after their battles against evil and their performance at the Daihasei festival.
- 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.
- I Just Want to Have Friends: She is eager to have friends as she enters Tokiwadai. At first, her boastful attitude turns several people away, but she ends up becoming friends with Maaya and Kinuho.
- 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. However, 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.
- 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.
- Overshadowed by Awesome: She's actually a really powerful Esper. But she goes to the same school as two Level 5s...
- Phrase Catcher: Specific to Kuroko: every time she shows up, Kuroko always mutters "Kongou... Mitsuko." in the same tone of voice, like a curse.
- Rich Bitch: Intentionally acted like this initially, because she misguidedly thought it would be the best way to get friends.
- Screw the Rules, I Have Money!: Thanks to her wealth, she believes that she can automatically cover any damages she causes during battle with her money.
- 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.
- 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 in the anime. 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.
Misaki Shokuhou
Junko Hokaze
Junko Hokaze
- Voiced by: Minami Tsuda (Japanese), Michelle Lee (English)
A friendly third year girl who acts as the face of sorts for Misaki's clique. She's quite friendly and slavishly devoted to the Queen. She's a Level 4, and her ability Rampage Dress allows her to manipulate the electric signals in her cells to perform past the limits of her physical abilities.
- Afraid of Their Own Strength: She's noted to have the potential to become a Level 5, but subconsciously holds herself back to avoid hurting people. As a kid, she repeatedly told people not to get near her so they wouldn't get hurt.
- Ambiguously Gay: Junkos's feelings for Shokuho, her " Queen", are clearly very strong, but their exact nature remains ambiguous. The Junko focused spinoff "Astral Buddy" plays this up the most. Here she learns for the first time that lesbians exist and contemplates, while extremely flustered, wether her feelings for Shokuho are actually lesbian love. However we never get a conclusion to that line of thought. Theres also a scene where Shokuho orders Junko to give her a massage. The way the scene is depicted makes it come across as very intimate and Junko is both extremely flustered and ecstatic throughout.
- Anime Hair: She's most commonly referred to as the ringlet curls girl thanks to her rather improbable hair. How she gets it all up under her swim cap is anyone's guess.
- Ascended Extra: She's the main character in the spinoff A Certain Scientific Railgun: Astral Buddy.
- Because You Were Nice to Me: The reason she's so loyal to Misaki is because she used Mental Out to help Junko control her Super-Strength when they were younger.
- Big Damn Heroes: In the past, she saved Misaki from a fire with help from Satori's telepathy.
- Birds of a Feather: She gets along surprisingly well with Mikoto. The pair bond over their mutual age inappropriate love of Gekota.
- Boxing Lessons for Superman: After the Ideal incident, Junko, who was already superhumanly strong and fast due to her esper power, studied martial arts in order to become stronger.
- Brains and Brawn: Has this dynamic with Misaki. Misaki is intelligent and paranoid, is Athletically Challenged and her esper powers rely entirely on Mind Manipulation abilities. In contrast, Junko is naive to a fault, is very athletic and her esper powers make her a Lightning Bruiser powerhouse.
- Chuunibyou: Junko used to warn others not to approach her because of her "inner destructive urges". While justified in part by difficulties controlling her full power, she feels deeply embarrassed whenever it comes up in the present day.
- Commonality Connection: She bonded with Mikoto over their love of Gekota.
- Compressed Hair: She's somehow able to hide her Regal Ringlets near completely within a swimming cap that doesn't even bulge. Mikoto doesn't even recognize her until she takes the cap off and can only stare in shock as her hair all pops free.
- Cool Big Sis: To Yuuri Senya. This comes from Senya admiring her strength from when they were kids.
- Cute Bruiser: Junko appears to be another ladylike Ojou of Tokiwadai, but she's not to be underestimated. Her punches and kicks are superhumanly strong due to her esper ability, she can lift and throw steel beams, and when Arei Houjo tried to blind her by throwing a liquid at her eyes, Junko countered by headbutting Arei and breaking her nose.
- Entendre Failure: When Aogami Pierce is selling risqué 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.
- Even the Girls Want Her: Junko is shown to be popular in Tokiwadai and has a lot of female admirers.
- 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.
- Healing Factor: She has a fairly powerful one, healing so fast that she seemingly doesn't get injured in the first place.
- Hidden Buxom: You wouldn't necessarily know it, but she's actually just as stacked as Misaki Shokuhou. It's less noticeable, partly because she carries herself more modestly, but also because her preferred model of bra is a bit too small for her.
- The Ingenue: She has a very naive and innocent nature, especially when it comes to romance and sex, such as when she was unable to comprehend comprehend the Power Perversion Potential of Aogami's Dream Cards containing Erotic Dreams about girls.
- Lady and Knight: Her lady being Misaki, who she always makes sure is within arms reach.
- Lightning Bruiser: Her power makes her strong enough to break through reinforced walls and fast enough to jump between roofs.
- Long Hair Is Feminine: She's a girly girl with very long hair, which she keeps in an Ojou Ringlets hairstyle.
- My Greatest Failure: Junko agonizes over being unable to protect her friends while she was in the Ideal institute. She also regrets pushing them away due to her difficulty in controlling her powers.
- 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: Until she gets her own spinoff, she's never given any sort of name and was only identified as Ringlet Curl Girl.
- The Nose Knows: While her esper ability is mainly used to enhance her physical strength, she can also use it to enhance her senses. She is able to track down her stalker by hunting down the smell of her perfume.
- 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. Afterward they're shown talking again, meaning Junko really did want to be friends. She even gives Mikoto lessons in Astral Buddy on how to use her electricity to strengthen her body.
- She even strikes up a friendship with Gunha Sogiita, inviting him for tea and a spar in the spin-off Astral Buddy.
- Practice Target Overkill: When she was younger, she hit a target hard enough to lodged it in a wall. It is noted that the wall was designed to withstand a trailer truck hitting it.
- Regal Ringlets: She has multiple large ringlets in the back. She was even known as the Ringlet curl girl until her actual name was finally revealed. They evidently require some work to maintain, as she's seen without them (wearing long braids instead) when she's briefly hospitalized in Astral Buddy.
- Shock and Awe: The nature of Junko's power is electrical-based. And while she normally focuses it on giving herself enhanced strength and reflexes, while under the effects of Astral Buddy she can project it outwards similar to Mikoto or create an Ion Sheath to ward off other electrical attacks.
- 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.
- Super Mode: When she gets serious she can use her full power, which causes her to be wreathed in electricity and her hair and eyes to change colors. In this "high-burden" state, she gains Super-Strength and Super-Speed to the point she can basically spar with Gunha Sogiita, a Level 5 Esper, though only for a short time period before it overtaxes her from the headaches and strain on her body.
- Super-Speed: One application of her ability.
- Weirdness Censor: Like most Science afflicted characters, Junko assumed the ghost following her was the product of an esper power. To be fair, she was correct, as the ghost was actually an Esper with an Astral Projection ability.
- Worthy Opponent: She views Mibuki as this, after she managed to flip her and reflect her attacks.
Ayu Mitsuari
Iruka Yumiya
Iruka Yumiya
A student at Tokiwadai and the captain of the archery club. Her level 4 esper power, Wave Conductor, allows her to manipulate sound, light, or anything with the properties of a wave. She can amplify them and focus them to achieve a variety of effects. She's also the younger sister of Rakko Yumiya, a member of the Dark Side team SCHOOL.
- Achilles' Heel: Water, which can short out her lasers or waterlog her whistle depriving her of her weapons.
- Ambiguously Gay: Heavily implied, as her obsessive fixation on Junko Hokaze treads into both Stalker with a Crush and I Want My Beloved to Be Happy territory. It's also quite easy to read romantic subtext into her relationship with Arei Houjou.
- Bow and Sword in Accord: A bit unusual given that her bows and sword are mundane laser pointers and a military flashlight made lethal thanks to her powers.
- Brown Note: Iruka wins an archery competition with Junko by twanging the string of her bow and using her esper power to affect her senses, causing Junko to miss her next shot.
- Closet Geek: She's actually a fan Gekota, thanks in part to Junko's influence.
- Crazy-Prepared: She not only lures Junko to a deserted warehouse but also reveals the dozen of laser pointers she had procured for their duel to mitigate the drawback of using her ability, while her flashlight/laser blade is equipped with a large capacity battery.
- Finally, there's her trump card, a prism that acts as her prosthetic right eye which she can turn into a laser turret at the cost of burning it out.
- Explosive Overclocking: She can rapid-fire her lasers but this will inevitably break them. Thus she carries extras to compensate.
- Fake Weakness: Iruka baits Junko into attacking her right side by making her think her right eye is blind, allowing her to attack Junko in the moment of confusion when she realizes her mistake.
- Gale-Force Sound: Iruka can use her esper power on a whistle to create a sound blast.
- Hiding Behind Your Bangs: Her bangs cover her right eye. She was injured during an incident in Ideal, and uses the hair to cover up both the resulting scar and the replacement eye she got.
- Laser Blade: Iruka can use her esper power to turn a flashlight into a laser sword that can easily cut through steel beams. She even named it after a famous Japanese sword.
- Light 'em Up: Iruka's power allows her to manipulate, amplify and focus light. She normally uses this to turn simple tools like laser pointers into weapons by weaponizing the light they produce and turning it into lasers. She can also produce blinding flashes of light from her palms to stun her opponents.
- Meaningful Name: Her given name means "dolphin" and her surname means "bow and arrow", both of which tie into her ability to weaponize sound and her archery skill. Iruka also likens her laser pointers to hunting bows in her fight with Junko.
- Unwitting Pawn: To Arei in order to lure out Junko and gather data on her, not that Arei herself enjoyed doing it and ultimately to Ayu Mitsuari in another one of her plots against Misaki.
Arei Houjou
Arei Houjou
A technical exchange student to Tokiwadai who was allowed entry into the school despite being a Level 2 Esper thanks to her skills. Her ability Whisper Bell allows her to hear emotions as sound, which becomes particularly deadly when combined with her shinobi training.
- Big Brother Worship: Greatly idolizes her brother, Seigo. So much so that she took part in his and Mitsuari's plans.
- The Dragon: To Iruka Yumiya. Although it is revealed that her true alliance was with her brother and by extension Mitsuari.
- Ninja: A kunoichi from the Houjou family.
- Sensor Character: Her ability allows her to physically hear emotions around her as distinct tones.
- Weak, but Skilled: While officially designated a Level 2 esper, Arei's constant training and application of her ability effectively made her a Level 3.
The Dormitory Supervisor
Tokiwadai Dormitory Supervisor
Voiced by: Hitomi Nabatame (Japanese) and Cynthia Cranz (English)
If there is one reason why you don't break Tokiwadai's rules, this woman is that reason. As Supervisor of Tokiwadai, it's her job to make sure the tenants don't break the rules, and she provides plenty of reason to keep them from doing so. Though a non-esper, her skills in "subduing" (i.e., 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.
- 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◊. - Old Maid: 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...
- One-Man Army: She gets a scene in a manga omake where she takes down a paramilitary squad out without using weapons or powers.
- Only Known by Their NicknameKuroko: Well good day Dorm Mother. Of course we were not up to any mischief.
- Perpetual Frowner: She only smiles around Daigo or little children.
- Scary Shiny Glasses: This happens before she disciplines someone.
- 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, Railgun 1/S), Amanda Gish (Railgun T)
Maaya (left) is voiced by: Yoshino Nanjo (Japanese) and Tia Ballard (English)
A pair of Level 3s in Tokiwadai's Swimming Team who hang around with Mitsuko a lot. Neither of them play a very prominent role in the series, except for one instance. Kinuho's ability is Hydro Hand (water manipulation), while Maaya's is Float Dial (buoyancy manipulation).
- Big Damn Heroes:
- In Railgun T, Episode 6, 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 T, Episode 2 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 Episode 5 seems to have finally gotten both of them quite angry.
- Let's Get Dangerous!: Against Baba Yoshi after he hurt Kongou.
- 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.
- No Name Given: Until the second episode of the first season of Railgun, the duo have no names at the time they are introduced in the manga.
- Supernatural Suffocation: Kinuho is capable of drowning Baba in a sphere of water.
- Those Two Girls: Apart from being Kongou's clique, they do not seem to have any prominence in both Index and Railgun.
- Water Is Womanly: Kinuho is a Level 3 Hydro Hand and a caring, girly schoolgirl who even knows a lot about swimsuits.
Yasumi Usukinu
Yasumi Usukinu
Voiced by: Nozomi Masu (Japanese)
A 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.
- Stalker with a Crush: For Mikoto. Mikoto even considers her just as bad as Kuroko in this regard.
- 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.
Yuri Sakibasu
Yuri Sakibasu
A Level 4 student of Tokiwadai who appears exclusively in the Railgun sidestory volumes included in the limited edition video releases of the third season of Index. She is a member Misaki's clique due to Misaki's interest in her power, Carbon Search, which allows Yuri to analyze anything with carbon in it. Mikoto encounters her when Yuri challenges Kuroko in a violin competition.
- Achievements in Ignorance: She is capable of using magic despite being an esper, as she can use her abilities to analyze her own body and keep it from breaking down. She is ignorant of this because... well.. she has the same Weirdness Censor regarding magic as most science side characters do.
- Going Commando: It turns out she doesn't wear underwear, apparently due to "some personal belief". What this belief might be is never elaborated on. Needless to say, this eventually proves to be a problem, especially given the rather short Tokiwadai school uniform skirt.
- Magic Feather: She believed can make the best violin music since she uses an antique violin. Mikoto and her friends disagree, saying that Yuri is just talented, proving it by having Yuri perform with a regular violin.
- Magic Music: By mimicking the actions of her mother's Stativarius Tam Lin violin, Yuri was able to use her Stativarius Ainsel to invoke elemental spells, not that she actually knew she was casting magic.
- Self-Made Man: At the age of five, she invented a trading card game that netted her and her lower-class parents incredible wealth. It was with this wealth that she was able to purchase from an auction a centuries-old violin for at least 100 million yen. Said wealth would cause issues with her mother, who felt it wasn't getting them the respect from the upper-class.
- Ojou: Something of a deconstruction. She acts like one — fairly convincingly, having become fabulously wealthy at age 5 — but unlike her, her parents didn't grow up rich and don't instinctively know how to handle high society. This disconnect causes Yuri some distress, and she feels guilty about having put her parents in such a situation.
Tokiwadai First Year Arc (Beware Unmarked Spoilers!)
Sha Danshan & Co.
General
- Coordinated Clothes: The clique seems to be made of girls with dark hair.
- We Help the Helpless: Sha and her clique were big believers in using their powers to help others. It is implied this is part of Sha's ploy to gain good publicity.
Sha Danshan
- Arc Villain: Of the First Year Arc.
- Bitch in Sheep's Clothing: Sha presents herself as a kind, wise, and delicate leader of her clique to the public. While delicate, events of the First Year Arc reveal she's anything but kind, with her true character instead being a sociopathic schemer willing to endanger all of her classmates to engender her plot to take down Tokiwadai.
- Delicate and Sickly: She was born with a delicate constitution, earning the title of "Infirmary Empress" because of her constant trips to the infirmary.
- Faux Affably Evil: Once she drops her demure girl act, she sadistically disposes of all loose ends by siccing prehistoric animals on her pawns.
- Power Copying: If the subject she recreates happens to be an esper, then she can also have the copy use their original's powers. Sha does note that the copied powers are weaker than the original's, whether it is because the object she used didn't have enough residual memories or that her power isn't strong enough, but she plans to rectify the issue with further training.
- Psychometry: Her power grants her the standard residual memory reading of psychometry, but she can further utilize those memories as fuel to 3D print the owners of those memories as phantasms under her control.
Mikagami Nagisa & Co.
General

Komoe Tsukuyomi
Komoe Tsukuyomi
One of the Seven Wonders of a Certain High School
The White Smoker
Voiced by: Kimiko Koyama (Japanese) and Jad Saxton (English)
Chemistry professor of Touma's high school. She looks nowhere like a teacher, but it has been said that she's one of the older characters in the novels. She hasn't undergone the Ability Development Program, allowing her to use magic to heal Index in the first arc. She also teaches a special class to survivors of the Level Up virus in Railgun.
- 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).
- All Girls Want Bad Boys: One of the things that she finds attractive about Touma is how he was a "naughty boy" when teaching him for the first time.Komoe: Well, Kamijou has been quite naughty ever since he came to the school. A lot has happened. Yes, a lot. Hee hee. Hee hee hee hee...
- 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 upstairs, 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.
- Curtains Match the Window: Her eyes are the same color as her hair.
- Hard-Drinking Party Girl: A chain-smoking alcoholic young girl...note
- 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.
- Pink Means Feminine: Her hair, eyes, and clothing are pink. Even her car is pink! It reflects her childish, but maternal personality as a teacher.
- 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.
- Teacher/Student Romance: Towards her "Kamijou-chan".
- 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. In the movie, her car is shown having support devices typically used by the disabled to reach all the controls.

Pierce Aogami
Pierce Aogami
Voiced by: Yoshihisa Kawahara (Japanese) and Scott Freeman (Season 1 & 2), Patrick Mc Alister (Season 3) (English)
Touma's friend and classmate whose real name is unknown. A funny individual who tends to notice his bad luck, and calls him "Kami-yan" in a different way. He is a self-confessed pervert, lolicon, and masochist who enjoys being punished by his teacher, Tsukuyomi. He is always seen with Motoharu. He, Motoharu, and Touma are known as the three idiots in their class as they have the lowest test scores.
- Badass Normal: The Daihasei arc shows that even though he doesn't appear to have any esper abilities, he's skilled and agile enough to contend with espers. Pre-amnesia Touma also described him as someone who was tough and could take care of himself.
- Book Dumb: It’s implied, as he, Touma and Tsuchimikado are collectively referred to as the Baka Trio. Yet...
- Class Representative: ... he’s somehow this despite the above.
- Continuity Cameo:
- He shows up briefly in the second season of Railgun, where he has a job as a Gekota mascot. He freaks out Febri when he takes the head off.
- He shows up at the second chapter of "Indian Poker" arc ("Blau") of the Railgun manga (adapted to Railgun T, Episode 16) as a class-S dream maker who gives out his dreams for free by the name "Blau". What are his ever-popular dreams, you ask? Sex dreams. Including sex dreams of famous people. Including Level 5's. Including the two Level 5's who happen to be right next door...Mikoto: Excuse me. I need to visit the next shop over...
Junko: She 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.
Junko : Oh, no. Together these two can easily pull off the perfect crime...
- Eyes Always Shut: As seen in the picture.
- Everyone Calls Him "Barkeep": His "name" means "blue-haired-guy-with-piercings." It's what Touma calls him because he doesn't know what Aogami's real name is. Likewise, we have no idea what his real name is, either.
- Extreme Omnisexual: His stated type is basically anything that can (even technically) be classified as a human female."Ha, you’re too naïve, Kami-yan. I have a wide range of acceptance when it comes to women: not just fallen female main characters but also foster sisters, foster mothers, foster daughters, twins, widows, senpais, kouhais, fellow classmates, teachers, childhood friends, ojou-samas, blondes, brunettes, brown-haired, silver-haired, long-haired, medium-haired, short-haired, girls wearing bobby pins, wavy-haired, twintails, ponytails, one-sided ponytails, twin braids, ahoges, curly-haired, girls in sailor clothes, blazers, judogi, kyuudougi, kindergarten nurses, maids, policewomen, witches, shrine maidens, nuns, military women, secretaries, lolis, shotas, Tsunderes, cheerleaders, stewardesses, waitresses, goth girls wearing black, goth girls wearing white, girls in China dresses, frail girls, albino girls, fantasists, girls with split personalities, queens, princesses, thigh-high socks, garterbelts, girls who cross-dress as guys, girls who wear glasses, girls who wear an eyepatch, girls who wear bandages, girls in school swimsuits, one-piece swimsuits, bikinis, V-shaped bikinis, bikinis that barely cover anything, youkai, ghosts, animal-eared girls, etc. — any female is within my area of acceptance."
- I Just Want to Be Special: Repeatedly mentions his desire to be popular.
- 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.
- Noodle Incident: He gets detained and questioned by the authorities a lot, apparently because they see him as a suspicious person. In NT Vol 6, it mentions this is the 43rd time in the past year this has happened.
- Ordinary High-School Student: In contrast to the other two members of the Idiot Trio, he really is ordinary. Or is he?
- Otaku: Exaggerated. See his rant above.
- Red Oni, Blue Oni: Despite having blue hair, he's most likely the Red Oni with Motoharu.
- Teacher/Student Romance: His shameless crush on Komoe-sensei.
Aisa Himegami
Aisa Himegami
Deep Blood
Voiced by: Mamiko Noto (Japanese) and Lindsay Seidel (English)
A 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. This power also killed her friends and family after being turned into vampires, prompting her to look for a way to remove her abilities.
She is a naturally occurring esper, which is called a gemstone.
- A-Cup Angst: Subverted. Aisa is a C-cup but considers it puny and wanted to have a bust size like Seiri's, which aggravates Mikoto who is viewing her dream via an Indian Poker.
- Back from the Dead: Aureolus Izzard killed her with his reality-warping powers, but Touma reversed the effect with Imagine Breaker.
- Big Eater: She keeps her slim figure despite wolfing down burger after burger.
- Bloody Murder: Her blood is highly toxic to vampires.
- Born Winner: Being a gemstone, she was born with her power. She certainly doesn't consider herself a winner.
- Cloudcuckoolander: She has her moments, such as pretending to be a magician and calling a taser baton as her magic wand, trying to kill the fleas on Sphynx with insecticide or telling a corny horror story.
- Crippling Overspecialization: Her Deep Blood ability makes her an incredible vampire slayer, but ONLY a vampire slayer. There's no other supernatural creature her esper powers work on. This led to her I Just Want to Be Special issues listed below.
- Dark and Troubled Past: She got her entire family and all of her friends killed, but doesn't seem to be bothered too much about it now.
- 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.
- New Transfer Student: She went from Kirigaoka Girls' Academy to A Certain High School.
- Nuns Are Mikos: Played straighter than usual, as she's a Christian who only dresses like a Miko.
- Power Incontinence: She has no control over her ability without her cross.
- Power Nullifier: The cross on her chest blocks her vampire attraction abilities.
- The Quiet One: If she does talk, it's usually very brief.
- Sailor Fuku: The school uniform.
- Too Spicy for Yog-Sothoth: Her blood will kill any vampire that drinks it, but that doesn't stop them from trying to take a sip.
- Trademark Favorite Food: Burgers.
- Vampire Hunter: Subverted Trope. While her blood is toxic to vampires, it also attracts them to her, and she would rather be left alone by those beings altogether.
- Victim of the Week: After an ill-fated encounter with Oriana. Fortunately, she lives.
Seiri Fukiyose
Seiri Fukiyose
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.
- Academic Athlete: She's both an ace student and an athlete at school.
- Accidental Pervert: It's a Running Gag that Touma ends up in a perverted situation involving her, though once it was actually reversed and she ended up walking in on him when he was changing.
- Adaptational Curves: 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. The light novels ended up adopting this, as shown in the illustrations for Volumes 9◊ and 10◊.
- Adapted Out: As a result of her seiyuu taking a leave of absence, Fukiyose's cameos in Railgun T gets replaced by a character or in one case, a scene involving her gets replaced entirely with a different one.
- Berserk Button:
- She gets very angry when people complain about bad luck around her. To her, luck is just a loser's excuse when they don't want to work hard and take responsibility for their mistakes. She's completely unaware that Touma's bad luck is real.
- Her classmates acting like perverts have into a Pervert Revenge Mode and physically beating them up as a response, something that actually gets her into trouble with the teachers.
- Buxom Beauty Standard: In the anime, she has a very busty figure, which both Touma and the camera constantly focus on. Aisa is also envious of her bust size.
- D-Cup Distress: She buys shoulder massage devices to relieve the strain of her large bust.
- Death Glare: She is often glaring at her classmates in a threatening manner when they're being immature.
- Fitness Nut: She's an athletic-minded health nut who is obsessed with healthy foods and products.
- Forehead of Doom: She has a sizable forehead, which earned her the nickname "Forehead Deluxe". Not helped by the fact she usually has hairstyles that indirectly emphasize how big her forehead is. She's also constantly giving headbutts to the boys when she's in Pervert Revenge Mode.
- Hair-Trigger Temper: She's often frustrated by how perverted the boys in her class are, often getting into Pervert Revenge Mode if she even hears them having lewd conversations which ironically gets her in trouble with her teacher, despite being otherwise a ace student.
- In-Series Nickname: "Iron Wall Girl", because she's the only girl in the class that seems to be "immune" to Touma's charms.
- Locked Out of the Loop: Doesn't know about Touma's adventures and the Magic Side.
- Ms. Fanservice: Played as such in the anime, where she has a much bustier figure, and is involved in various Accidental Pervert moments, such as inadvertently giving Touma a panty shot, being walked in while topless with Godiva Hair to cover her or getting splattered by water from a busted hose that ends up giving her a Sexy Soaked Shirt.
- Not So Above It All: Despite her constant chastising the "Delta Force" over their stupid antics, she occasionally finds herself getting dragged alongside their stupidity.
- Perpetual Frowner: She usually has a serious, no-nonsense demeanor, to the point her classmates believe she's incapable of doing anything that is fun.
- Prim and Proper Bun: She ties up her hair in a bum when she "gets serious" about organizing something in class.
- Reluctant Fanservice Girl: She dislikes how perverted her classmates usually are, and how often she accidentally gets into fanservice situations that fuel their perversion.
- Sailor Fuku: Her normal school attire is the classic Japanese uniform with a sailor motif.
- Sugar-and-Ice Personality: A caring mother figure to her classmates beneath her impassive facade.
- Team Mom: She often acts like a nosy mother hen to her class, such as encouraging them to participate on activities or pushing healthy food on them. This is also why she's often butting into the affairs of the "Delta Force", as she sees them as underachieving misfits who need her help to keep them in check.
- Trademark Favorite Food: Health products from TV shopping channels. This also includes the infamous Musashino Full-Cream Milk introduced in Railgun. No wonder she developed so nicely...
- Tranquil Fury: She doesn't become openly angry with Touma's "unfortunate" actions.
- Tsundere: Despite how she acts frustrated toward Touma, the manner in which she goes out of her way to interact or reprimand him implies she does have a crush on him.
- Use Your Head: Her favorite way of punishing Touma whenever he does or says something that annoys her is to headbutt him, which puts further emphasis on her huge forehead.

A mysterious senpai 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.
- Clingy Jealous Girl: When Touma gets Fake love letter from High Priest thinking that it's the real deal, she is pissed.
- Didn't See That Coming: She beat Tsuchimikado down with ease... until he started using magic, which she has no knowledge of.
- Eye Scream: Lost an eye in a battle with Tsuchimikado. She later gets a replacement.
- The Man Behind the Man: The previously mentioned Board member refers to her as his 'brain'.
- Locked Out of the Loop: She has great knowledge of Academy City, including its deepest secrets and its Dark Side. However, she appears to know nothing about the magic side.
- Love Makes You Dumb: She used to be confident and brilliant. Then Touma "died". She then spent her time "blankly sitting around like an idiot" until he came back. She's still depressed that she couldn't help during WWIII though.
- Love Letter Lunacy: Invokes this in her A Day in the Limelight short story.
- 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.
- Smug Snake: Though not a bad guy. Probably.
- Teen Genius: Said to be one, being the brain of a Board member and all.
- Tsundere: Subverted. She hates Misaki, but agrees to help her when she brings up Touma. When she finishes clearing Misaki of a hidden bug and gives her advice, she warns her to be careful. 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.

- 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.

An anime-exclusive character. He was a student at Nagatenjouki Academy, who dropped out prior to the events of the Silent Party story arc. He is the leader of an organization called STUDY (aka the STUDY Corporation), which seeks to prove technology is superior to esper powers.
- Better to Die than Be Killed: When STUDY is defeated, he launches a missile at Academy City in a last-ditch effort at revenge, then attempts to shoot himself in the head so he won't experience the explosion. 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.
- I Lied: Promised to give Mikoto the formula for the lollipops Febri needs to survive if she and Nunotaba did what he asked, then callously stomped the flash drive containing the data to dust.
- 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. Once she realizes they're just drones, the next time she fights dozens of them at once she just cuts loose and slaughters them en masse without issue, while carrying Febri on her back even.
- 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 Hurt a Child: Doesn't care who his experiments hurt. Later, he beats up Shinobu Nunotaba and gives her a black eye.

A geek who had been frequently bullied. Desiring revenge, he took Level Upper, gained the ability Synchrotron, and used it to terrorize Academy City as the Graviton Bomber.
- Complaining About Rescues They Don't Like: Mikoto saved him from some bullies once, but he rudely brushed her off, asking why she didn't save him sooner.
- Disproportionate Retribution: 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.
- Having a Blast: 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.
- 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.
- 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.
- Villainous Breakdown: He panics when Touma blocks the aluminum bomb he put in a child's toy, meaning he failed to kill anyone. Doing so confirms that he is the bomber.Hatsuya Kaitabi: Th-that's impossible! That was my maximum power!
- 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.

Shaei Miyama
Voiced by: Mayu Mineda (Japanese)
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.
- Blessed with Suck: Precognition isn’t so cool when the only thing you can see are other people getting hurt.
- Bully Magnet: Shaei's power caused him to be bullied and picked on at school.
- Cassandra Did It: Other children believed he was causing accidents rather than simply predicting them.
- Heroic RRoD: Use of his power causes Shaei severe stress and results in anemia and nosebleeds. Extensive use can even leave him bedridden.
- Intergenerational Friendship: With Kuroko.
- Magical Camera: Shaei 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 Shaei 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.
Mie Akikawa
Mie Akikawa
A middle school student at Touma's temporary school in New Testament who gets caught up in the chaos around Touma and Kamisato. Described as a "modern schoolgirl" who accessorizes as if she wants to attract attention but doesn't want to be seen doing so.
- Almighty Janitor: She volunteers as an assistant for the student council, despite not technically being a member. According to the secretary, she actually does about 80% of the council's work.
- Amazingly Embarrassing Parents: She sees her father as a dorky pushover, and can't see why her mother, a wealthy jewelry designer, chose to marry him.
- Cloud Cuckoo Landers Minder: Acts as this to Asuka Keshouin, despite being younger.
- Overshadowed by Awesome: Feels as though she's always falling under the radar no matter what she does. This isn't helped by Touma, who's consistently unable to remember who she is.
- Plucky Girl: Clearly intended as an homage (or perhaps an affectionate parody) of this character type, to the extent that she could have stepped straight out of a shoujo anime.
- Weirdness Magnet: Spends much of NT 13 suffering from this, although she does bring some of it on herself.

Jumpy Bunny
The student council president at Touma's temporary school in New Testament; she apparently got the job by accident. Noted as looking nothing like anyone's image of a student president, she's tiny, timid, and high-strung. Her nickname is "Jumpy Bunny" because she tends to jump up like a rabbit when startled. She is a Level 2 pyrokineticist.
- Expecting Someone Taller: When told that the student council president is a high school girl, Touma imagines a tall, mature and sexy upperclassman. On discovering that she's a diminutive Shrinking Violet, his immediate reaction is to ask for a do-over.
- Not Herself: Spends part of NT 15 being impersonated by Yuuitsu Kihara, while actually away in quarantine.
- Older Than They Look: She's roughly the same size as Komoe Tsukuyomi, despite being a high school student. She's a bit sensitive about this.
- Shrinking Violet: Shy, timid and insecure, with a tendency to hide behind other people (although given her size, that isn't always intentional). She relies heavily on Mie Akikawa for advice and emotional support.
- Signature Headgear: Wears a large bow in her hair that resembles rabbit ears.
Risako
Risako
A young girl who is one of the Child Errors under the care of Drencher Kihara Repatri. Implied to be around elementary school age, she is intelligent and determined, but also impulsive. She gets caught up in a number of the events surrounding Operation Handcuffs.- Break the Cutie: Hasuu Kihara tries to do this to her. He doesn't quite succeed, so in the end he just takes her hostage instead.
- Damsel in Distress: Spends much of GT volume 3 getting into lethally dangerous trouble and having to be rescued by various people. Then in GT volume 5 she gets taken prisoner by Hasuu Kihara and has to be saved yet again.
- Girlish Pigtails: She has red hair described as "done up like a piece of candy", which presumably means short twintails.
- Only One Name: If she has a last name, it isn't mentioned. As a Child Error, she has no family in any case.
- Plucky Girl: A deconstruction, as her pluckiness only leads her into increasingly dangerous situations which almost get her needlessly killed (and arguably do get some other people killed).
- Unwitting Instigator of Doom: She's one of the catalysts for Houfu Rakuoka's psychotic breakdown, is the subject of Vivana Oniguma's Heroic Sacrifice, and is arguably partly responsible for Drencher's as well. These in turn lead to her role in triggering Frillsand #G's desperate rampage in the Handcuffs aftermath. All this isn't entirely her fault, however, as the events of Operation Handcuffs were being magically twisted into abnormally disastrous outcomes by an outside force.
