President of the United States of America. Introduced in New Testament Volume 3.
- Adaptation-Induced Plot Hole: Averted! Almost 3 years before Katze's introduction in the novels, an additional scene was added to episode 15 of Index I (the angel fall arc) that involved Kuroko Shirai switching with the US President, who was implied to be Barack Obama. Despite this, the scene still fits Katze quite well.
- Big Damn Heroes: He saves Accelerator of all people from GREMLIN agents.
- Bunny-Ears Lawyer: During an important meeting with several important political figures, he was munching on a hotdog, reading a dirty magazine, and hitting on the females in the room. He's still the President.
- Expy: Fans can't help but compare his appearance with Rider from Fate/Zero. The fact that they both have a boisterous personality reinforces the point.
- In-Series Nickname: Mr. Scandal.
- National Stereotypes: Boasts about America being the land of guns.Roberto Katze: Don't even hold a gun if you can't hit. Are you trying to get yourself killed!? This is the world's largest gun country!!
- Our Presidents Are Different: More specifically...
- President Action: When he determined that some organization was subverting Americans, including members of the White House and various defense agencies, he took it upon himself to personally investigate, ditching his bodyguards.
- President Minority: In the Raildex-verse, he's the third President of Latino descent elected to the office.
- President Playboy: Shades of this. And yet he makes Bill Clinton look tame, considering he's currently engaged to be married, but yet is still a flirt and openly talks of his sexual prowess.
- Raging Stiffie: Suffered one during a meeting due to his dirty magazine and the females in the room. His secretary was disgusted.
- Reasonable Authority Figure: After Touma tells him that Othinus has pulled a HeelFace Turn and is no longer a threat to the world, he's rightfully skeptical, then listens to him after Touma gives his argument. He then gives a heartfelt speech to the world urging them to believe in Touma.
- Recognition Failure: He gets upset frequently that no one seems to be able to recognize him as the president, even though he has a very distinctive appearance.
Misuzu Misaka is Mikoto's mother, first appeared in volume 9 and again in volume 10, Volume SS and Volume SS2. Currently studying at a university. Mikoto often comments her mother acts more like a child than she herself is. Misuzu is very weak to alcohol, and after getting drunk she has a habit of clinging to a young guy she finds attractive, as Touma and Accelerator found out in SS1, when she got drunk and clung onto Accelerator, who called a taxi to take her to her accommodation.
- Alliterative Name: Misuzu Misaka
- Amazingly Embarrassing Parents/Doting Parent/Shipper on Deck: She's overly happy about Mikoto "seeing" Touma (whom she calls "the boy you care about so much"), much to Mikoto's embarrassment.
- Can't Hold Her Liquor: Gets drunk very easily.
- Hammerspace/Bag of Holding: Somehow the ingredients and tools for cheese fondue fit all in her bag in Season 2 Episode 11.
- Idiot Hair: Just like Misaka, she has one, though it's normally down and hidden among the rest of her hair. However, hearing about how Misaka has a boy she knows (Touma) brings out the Shipper on Deck in her and causes the hair to pop up.
- Mama Bear: She planned to make Mikoto move out of Academy City when she felt it had become too dangerous. She relents when she realizes Mikoto has people like Touma to protect her.
- Mum Looks Like a Sister: As our favorite resident stalker aptly describes it:Kuroko: What is this?! She's like a bigger version that still maintains that air of Onee-sama!
- Older Than She Looks: Though it doesn't come quite naturally.
- One of the Kids: Her immaturity is a constant source of exasperation for her more mature fourteen year old daughter.
- Sentimental Drunk: Gets very happy and flirts with everybody while intoxicated.
- Strong Family Resemblance: Of Mikoto. Also a source of confusion for Touma and his dad, both of whom mistook her for Mikoto's older sister.
Mikoto's father, who first appears in Volume SS2. His self-created job description is "Finding the flaws in this world and correcting them". He seems to be interested in gemstone espers.
- Badass Boast: Remember, he pretty clearly knows exactly who he's talking to here.Tabikake: It's true that there may not be anything in this world that can take you [Aleister] out in one blow. However, my job is to point out what this world lacks. If the world is lacking such a thing, then the ball's in my court. That is why I gave you that warning. So keep that in mind.
- Mysterious Watcher: He has contacts all over the world and is strangely interested in gemstone espers.
- Offscreen Moment of Awesome: In SS2, he goes on an adventure with Toya, Toya's Co-Worker, and Gemstone Girl while trying to escape from her pursuers. All the readers know was that it somehow ended with the group faking their deaths by blowing up an unmanned Cessna airplane as it flew through the air.
- Papa Wolf: He has the guts to threaten the most powerful man on the planet if he ever tries to use his family.
- Walking the Earth: He makes it his mission in life to "find the flaws in this world and correct them".
Touma's dad. He is a traveling businessman who has a habit of collecting dozens upon hundreds of good-luck charms in an attempt to alleviate Touma's own bad luck.
- Badass Bystander: In SS2, he saves the Gemstone Girl from the thugs chasing her.
- Chick Magnet: Now we know where Touma got it from. Unlike Touma, he's prone to flirting back, even if his wife is standing right next to him.
- Give Him a Normal Life: Inverted. Due to Touma's misfortune, the people around him treated him like a plague, and he was even abducted and brutally beaten. Toya, completely terrified at the prospect of Touma actually being killed by these overly superstitious people, sent Touma to Academy City, where "superstition doesn't exist", immediately after he graduated from kindergarten.
- Locked Out of the Loop: Has no idea about magic and the full extent of Touma's adventures.
- Male Gaze: Ogles any attractive girl he meets, much to his wife's chagrin.
- Mike Nelson, Destroyer of Worlds: Cast Angel Fall by accident. He never learns about this.
- Off Screen Moment Of Awesome: In SS2, he goes on an adventure with his Co-Worker, Tabikake, and Gemstone Girl while trying to escape from her pursuers. All the readers know was that it somehow ended with the group faking their deaths by blowing up an unmanned Cessna airplane as it flew through the air.
- Papa Wolf: He admits that he isn't a good fighter, but he'll be damned if he were to just stand there and watch his son get hurt.
- Shipper on Deck: Is happy to see Touma interacting with girls, mostly Sasha Croitsef.
- Unwanted Harem: Similar to Touma, he seems to attract nearly any girl he meets, which enrages his wife and his jealous coworkers.
- Weirdness Magnet: Like Touma, only no one's intentionally dragging him into things nor does he have Imagine Breaker nullifying his luck. According to his co-worker, this happens all the time (without his wife's knowledge of course). Let's see what he's coincidently caused so far:
- Causes Angel Fall by accident, successfully summoning Archangel Gabriel and nearly destroying the world.
- Met Ridovia Lorenzetti in Italy and moved her with his willingness to help his son, changing her views of the Japanese and deciding to capture Academy City in a peaceful manner, thus setting off the events of the Daihasei Festival Arc.
- While in South America, he helped give a young girl at a train station directions. Later that night, he encounters not only Tabikake Misaka, but also the same girl again (whom turns out to be a Gemstone, one of less than 50 in the world) being chased by a group of men in black. They end up spending the night escaping and eventually faking their deaths by somehow blowing up a Cessna airplane while it's in the air.
Touma's mom and Toya's wife. She is a famous paraglider.
- Barely-There Swimwear: Wore this at the beach during the Angel Fall arc, much to Toya's delight and Touma's horror. Especially since Touma was seeing her as Index at the time.
- Clingy Jealous Girl: Really hates it when her husband attracts other girls.(In a disturbingly sweet and gentle voice) "Toya-san, you're doing it again!!"
- Fangirl: Of Teen Idol Hajime Hitotsui.
- Heavy Sleeper: It is mentioned that she can easily sleep through a huge commotion.
- Locked Out of the Loop: Has no idea about magic and the full extent of not only Touma's, but also Toya's adventures.
- Older Than She Looks: Misuzu is annoyed because while they both look younger than their actual ages, Misuzu has to work at it and it therefore doesn't work as well. It is mentioned that she is roughly the same age as Toya, but she looks like she's in her early twenties while he's starting to go gray.
Touma's young cousin. So far, her only appearance was during the Angel Fall arc, where she spent most of it blissfully unaware she was in the body of Mikoto Misaka, frustrating Touma to no end.
- Genki Girl: She is an eternally cheerful little girl.
- The Glomp: She's constantly jumping on and clinging to Touma.
- Kissing Cousins: She flirts with Touma at times and claims there is nothing wrong with that.
- Locked Out of the Loop: Has no idea about magic and Touma's adventures.
- Meaningful Name: Her full name means "Youngest Princess of the Dragon King/God". This is a bit significant considering Touma's connection with dragons.
Sister of Leivinia Birdway of Dawn-Colored Sunlight, she has no knowledge of Magic, but is an important Political figure and therefore can not be allowed to become an Esper. She was involved in a case dealing with Alaskan Runes (The Stiyl SS in volume SP).
- Ascended Extra: She's a fairly minor character for the first half of NT, only to take a larger role in Vol 14 where she becomes a member of Kamisato's faction.
- Bodyguard Crush: Implied with Stiyl because of Rescue Romance.
- Defiant Stone Throw: Throws some rocks at Richard Brave. They don't hurt him, but the act gives Stiyl enough time to recover.
- Genius Ditz: She's very intelligent, to the point she's skipped grades and has been invited as a guest researcher on several fields, but she just doesn't get magic. Somewhat justified considering that most of what she hears about magic comes in the form of Magibabble completely lacking in context.
- Locked Out of the Loop: Doesn't know about the Magic Side and has no idea that Leivinia and her friends are magicians. She thinks Dawn-Colored Sunlight is just a club Leivinia hangs out at.
- Morality Pet: Her sister doesn't treat others like humans the majority of the time, but messing with Patricia is one way to get your whole organization destroyed, treaty between Science and Magic or not. Not to mention whatever she did to Richard Brave.
- Polar Opposite Twins: She and her sister look identical, but their personalities are completely opposite of each other.
The younger sister of Frenda of ITEM, and friend of Ritoku Komaba, the leader of Skill-Out. Fremea is introduced in New Testament.
- A-Cup Angst: Invokes this to completely own Leivinia Birdway, the leader of a magic cabal who is two years older.Fremea: And I wear a bra, so Im essentially the winner.Leivinia: What are you trying to do!? Are you trying to pick a fight with me, you damn brat!?!?!?
- Berserk Button: Insulting Shiage Hamazura. This is what made Fremea get into a fight with Levinia Birdway. She even talks back to Shiage's girlfriend, defending him on what a great person he is, and refuses to hear anything bad about him.
- Beyond the Impossible: At the climax of New Testament Volume 7, she manages through sheer force of will to control the AIM around her to end the Agitate Halation effect and turn Hisako Yakumi, who was an AIM thought being, vulnerable. A shocked Yakumi declares this is impossible because Fremea is a Level 0.
- Character Development: In New Testament 7, she goes from a little girl scared of everything and always waiting for a hero to save her to deciding to become a hero herself. At the beginning of the novel, when her classmates talk about a version of Santa Claus who abducts children, she is utterly terrified. At the end, when her classmates talk about the evil Santa again, she says not to worry; if he comes, she will protect them.
- Damsel in Distress: New Testament 7 where she gets 7500 heroes to come after her due to the effects of Agitate Halation.
- Damsel out of Distress: Manages to save herself by controling the AIM around her as a level 0 to destroy the Agitate Halation and an AIM thought being while giving a Touma-esque speech about how she Will Not Be a Victim anymore.
- Early-Bird Cameo: Sort of. In the novels she was introduced during New Testament, but a picture of her was shown during SS1. However, the picture of her was not properly described, nor was there an illustration given. In the anime however, her visage is clearly shown on Komaba's phone.
- Green-Eyed Monster: Is this to both Hamazura and Accelerator's respective harems, who immediately show vicious jealousy towards her.
- Has Two Daddies: Shiage Hamazura and Hattori Hanzou; there's even been an official artwork picture of all three of them having dinner together.
- Morality Pet: In a way, she's this for Shiage Hamazura and Shizuri Mugino.
- Nightmare Fetishist: Likes her gory horror flicks and zombies.
- Shut Up, Hannibal!: When she manages to gain control of the AIM field, Hisako Yakumi begs her to stop, saying her grand plan is too important for the development of humanity. Fremea says she doesn't care. All she wants is to bring smiles back to her friends by saving them.
- Strong Family Resemblance: Mugino assumed she was Frenda's ghost when they first met.
- Unwitting Pawn: She is manipulated into meeting both Hamazura and Accelerator and getting them to protect her.
- Verbal Tic: Essentially!
A serial killer whom the heroes briefly contend with and defeat during the Angel Fall arc. He only appears in Light Novel Vol. 4 and was excluded from the anime.
- Expy: Artist notes indicate that his design was based on Gollum. He also talks and acts like him a little.
- Hearing Voices/Split Personality: He has a meek personality and a murderous one who heeds the words of "Angel-sama", who commands him to kill people.
- Knife Nut: And his knife is also a Poisoned Weapon.
- Made of Iron: He doesn't really react to getting his teeth knocked out or his arm crushed, and he also ritualistically injures himself.
- Mundanger: He's just an ordinary serial killer, with no connection to the Science or Magic sides.
- Red Herring: He seems a probable suspect during the Angel Fall incident, but he was just an ordinary serial killer who was unaffected by the Angel Fall spell because of his Split Personality.
- Serial Killer: He had already killed 28 people when he is introduced.
An Iga Ninja who seems obsessed with bringing Hanzou Hattori back into the ways of the Ninja in order to create a ninja troop.
- Combat Pragmatist: Uses handguns and automatic weapons, believing that ninjas should keep up with the times.
- Fashionable Asymmetry: Her left arm is sleeveless up to the shoulder, and she has a metal shackle on her left leg.
- Ms. Fanservice: Which she uses to distract Shiage.
- Highly Visible Ninja: She advocates this principle.
- Technicolor Ninjas: Wears a bright yellow mini-yukata.
- Too Many Belts: Wears two belts over her bare midriff.
- Unwitting Pawn: Hanzou speculates this about her, since she has a list of Gemstones in her possession, someone might be trying to manipulate her from the shadows. Additionally in NT1 she was inadvertently used to find the location of where Hamazura, Hanzou, and Fremea were hiding.
A genius movie director. In the Arts and Sciences Side Story, she goes to Liberal Arts City to find inspiration, only to get caught up in an attack by the Magic Side. After the ordeal, she decides to move to Europe. In Volume 19, it is mentioned that she directed the movie Shiage and Saiai saw at the theater.
- Badass Bystander: She helps the heroes evacuate Liberal Arts City, which was about to sink into the ocean.
- Covert Pervert: She was the one who suggested Saten give Xochitl Barely-There Swimwear.
- Gag Boobs: They're an L Cup. Mikoto and her friends quickly became jealous.
- Rapunzel Hair: It goes down to her waist.
- Recognition Failure: Mikoto and her friends didn't recognize her until she gave her name. Once she does, then they fangirl about her.
- This Looks Like a Job for Aquaman: Used her fame and skill as a director to inform the people of Liberal Arts City that the city was about to sink into the ocean and that they needed to evacuate.
- Walking Swimsuit Scene: Spends the entire Liberal Arts Side Story in a bikini with a t-shirt.
Natural Selector Tournament
A girl who enters the Natural Selector Tournament in NT Vol 4 in an effort to prove that normal people are not to be overshadowed by espers, befriending and teaming up with Maria Kumokawa and Shuri Oumi in the process.
- Apologetic Attacker:Saflee: I am Saflee Opendays. My hobby is all kinds of physical fighting. If I broke any of your teeth, I apologize. I cannot do anything beyond apologizing though.
- Badass Bystander: She was someone caught up in GREMLIN's takeover of Baggage City.
- Badass Normal: Her martial arts allows her to deal with espers and gunmen.
- Back from the Dead: Marian Slingeneyer killed her with Dáinsleif, but Touma revived her with Imagine Breaker.
- Battle Ballgown: Her blue dress has armor underneath.
- Blood Knight: She enjoys fighting for the sake of causing "pure destruction": the right amount of force to defeat an opponent, no more, no less. She does not like fighters who hurt innocent people.
- Chronic Hero Syndrome: Has a strong sense of justice, like when she helped out an opponent whose daughter had been kidnapped.
- Expy: Her design is based on various fighting game characters who have strange reasons to enter a tournament.
- Honor Before Reason: She does not like the idea of running away.
- Power Fist: Her gloves are loaded with urethane.
A member of the Kouga School of Ninjutsu. She enters the Natural Selector Tournament in NT Vol 4 in an effort to find people with interesting abilities to analyze for the sake of her school, befriending and teaming up with Maria Kumokawa and Saflee Opendays in the process. She also appears in Railgun taking part in the Academy City jailbreak trial with several other members of her school.
- Badass Bystander: She was someone caught up in GREMLIN's takeover of Baggage City.
- Badass Normal: Her ninja skills allow her to deal with espers and gunmen.
- Back from the Dead: Marian Slingeneyer killed her with Dáinsleif, but Touma revived her with Imagine Breaker.
- Bare Your Midriff: Ties off her shirt.
- Combat Pragmatist/Crazy-Prepared: Fittingly for a ninja, she is armed to the teeth with concealed weapons and equipment. These include a flashlight to blind people, a water gun full of hot sauce, and alcohol to throw off an attack dog's sense of smell.
- Expy: Her design is based on the child ninja from Dororo and Kamui Den.
- Highly Visible Ninja/Technicolor Ninjas: Her outfit has a lot of pink. She advocates this principle, because her usual tactic is to get the opponents' attention so her teammates can attack them from behind.
- Older Than She Looks: She is 30, but a disorder stunted her aging, making her look like a child.
- Straight Man: To Maria and Saflee's antics.
- Authority Equals Asskicking: Kakeru is the leader and (by many definitions) the strongest member, being capable of easily defeating Magic Gods.
- Asskicking Equals Authority: Subverted. Kakeru fears that the girls only follow him around because of the unstoppable power of World Rejector. He's proven wrong when it's stolen by Yuiitsu, yet his faction treats him in exactly the same way.
- Battle Harem: They are all willing to fight for Kakeru.
- Foil: To the Kamijou Faction, both being groups gathered by the actions of (self-proclaimed) normal high school students with special abilities in their right hands. The Kamisato Faction is far more organised and focused around its central figure, in contrast to the loose association of the Kamijou Faction. However, it is also far smaller and (besides Kakeru) lacks members on par with a Saint or Level 5 esper (justified by being active for a much shorter period of time). It also is comprised entirely of Kakeru and girls interested in him, whereas the Kamijou Faction includes male members and female members who aren't interested in Touma.
- Satellite Love Interest: A noticeable difference between them and the Kamijou Faction. The female members are all obsessed with Kakeru and consider him their highest priority. That said, they do interact with each other and have interests outside the group.
- The Worf Effect: Played with. When first introduced, they are portrayed as a great threat to the Kamijou Faction. Salome even appears to be a danger to two different Level 5s. However, this is mainly because the Kamijou Faction never presents any organised resistance to them. Accelerator, despite his limited knowledge of magic, proves capable of fighting the entire faction on his own. If the two factions ever did meet in full-force, it's clear that the Kamijou Faction would win due to its vastly greater numbers (even using the most conservative estimate, over ten thousand) and more powerful members.
A mysterious teen. Like Touma, he has a mysterious power sealed into his right hand, called World Rejecter.
- Alliterative Name: Kakeru Kamisato.
- An Arm and a Leg: Yuiitsu Kihara cuts off World Rejecter. He eventually gets it back, but can't reattach it until he can get rid of his conflicted desires.
- Ascended Extra: His appearance is based on a discarded concept art for Gunha.
- Badass in a Nice Suit: Dressed in a dress shirt, tie, and blazer when he confronts the Magic Gods.
- Blatant Lies: The quote above given his capabilities. Subverted, since it's true.
- Brought Down to Normal: World Rejector is stolen by Yuiitsu at the end of NT Volume 15. Also a case of Brought Down to Badass, as he manages to take down even the larger Elements without the power (albeit with the help of his faction). He gets the hand back permanently at the end of NT Volume 17, but can't transplant it back on as he now has conflicted desires and would banish himself if he used it.
- Character Tics: He's constantly trying (and failing) to crack his neck joint. He confesses to Patricia Birdway that it's a meaningless habit he picked up to try to be less dull and uninteresting.He finally succeeds in cracking his neck when he realizes Touma doesn't share his view on their unique powers and situations.
- Cool and Unusual Punishment: Oddly enough, his power does this. He seals a Magic God into its idealized vision of a world, thus keeping them from ever wanting to leave.
- Did You Just Punch Out Cthulhu?: Hoo boy. His first appearance has him sealing Niang Niang and sending Nephthys running away with her tail between her legs with her organs left behind. To clarify, he beat two individuals capable of destroying and recreating the universe on a whim, just by opening and closing his hand! Not to mention that he crushed one of Nephthy's phases before she could complete it. That's right, he crushed a universe! Takes it a step further when, later on, he beats Noukan, the guy equipped to kill gods, to near death while heavily injured himself.
- Foil: His powerset is the exact opposite of Touma's despite the fact that they are both "ordinary high school students". To be clear, it sends the target into their ideal world, thus rejecting the current one and supplying the illusion of a world that will let them throw out the old one. Compare this to Imagine Breaker, which returns the world to normal, thus accepting the current and natural state of the world unaltered by supernatural events and the secret wish of magicians to be able to maintain the current world they live in (as demonstrated by Othinus). In addition, just as Touma's power is limited to the supernatural (ie, things that reject the natural laws of the world), Kakeru's is limited to those who wish for a new world. Those that have the determination to live and die in this world, despite its hardships, are immune to World Rejecter, as they do not "reject this world". It's taken a step further when we're shown he's also got a harem and life much like Touma. It's then deconstructed when it's revealed that he really is an Ordinary High-School Student who basically got Touma's life forced on him thanks to the Magic Gods. In a sense this makes him Touma who had a completely normal life.
- Hoist by His Own Petard: Yuiitsu Kihara tricks him into activating World Rejecter while he was holding conflicting desires, resulting in him being exiled to the same place he sends his victims. He is eventually rescued.
- I Just Want to Be Normal: He hates being given his power and being thrust into the role of a hero, so he takes his anger out on the Magic Gods after blaming them for this.
- Logical Weakness: World Rejector has no effect on people who are completely satisfied with their lives and have no desire to go to an idealized world.
- Meaningful Name: His full name can be read as "the gods' village is broken". Guess what happens to the Magic Gods during the arc he's introduced.
- Muggle: Prior to being given World Rejecter.
- Nerves of Steel: Stares down two of the most powerful beings in the universe without batting an eye.
- Ordinary High-School Student: Or so he says. He's saying the complete and absolute truth.
- Orgasmic Combat: Not him but the Magic Gods who get sealed by him go into a state of ecstasy as they're sealed into their ideal world.
- Outside-Context Problem: Apparently, none of the major faction leaders save Laura Stuart are aware of his existence. This includes Aleister Crowley, you know, the guy who has billions of microscopic cameras scanning his city at all times. Turns out there's a perfectly normal reason for this. Kamisato isn't from Academy City and didn't have World Rejecter a few days prior.
- Psychological Projection: When he learns of Touma's similar powers, he automatically assumes Touma wants to be normal just like him and would join him in his quest to get revenge on the beings who empowered them. He is thrown for a loop when Touma reveals his dedication to helping and protecting people.
- Rage Against the Heavens: He hates the gods and blames them for giving him powers and forcing him to be a hero, so he starts hunting down and banishing them.
- Red Right Hand: Literally. His right hand (the one that holds his power) is a lot less pallid in his official art than the rest of him.
- Silly Rabbit, Idealism Is for Kids!: He calls Touma naive for wanting to save everybody, saying the smart thing is to save one and leave the rest to die, because if you waste time trying to save everybody, you won't be able to save anybody. This turns into Silly Rabbit, Cynicism Is for Losers! when Touma consistently manages to save everybody by never giving up and using methods Kakeru never thought of, causing Kakeru to admit he was wrong.
- Unwanted Harem: Much like Touma. He thinks it's only because of World Rejector, and he isn't happy about it.
- Walking Spoiler: He's a mysterious character who appears at the end of NT Vol 13 to serve as the antagonist of the next book. He then proceeds to have major plot twist involving him that turns his character on its head.
- Yin-Yang Clash: What everyone fears will happen if he and Touma ever try to use their respective powers on each other. They do so at the end of NT Vol 14. Result: Imagine Breaker is erased by World Rejecter, but then the Invisible Thing comes out and nearly kills Kakeru. As far as Kakeru is concerned, Touma won that clash.
Ellen ArimuraA member of the Kamisato Faction. Neither a magician nor an esper, she specializes in tracking using forensic techniques.
- Awesomeness by Analysis: This is how she discovers that Fran is actually a spy from the Anglican Church.
- Lethal Chef: She tries to apply her chemistry knowledge to cooking, leading to horrendous results.
- Nerves of Steel: When Sample Shoggoth attempts to attack her (by thrusting a sharp tentacle at her face), she isn't frightened at all.
- Shameless Fanservice Girl: She doesn't hesitate to enter the male side of the bath when Kamisato is there (albeit when no one else is) and try to bathe together with him.
Claire TazumaA member of the Kamisato Faction. She is a Gemstone esper, whose ability gives her plant-like physiology and the ability to manipulate plant-based matter.
- Cyborg: In a sense. She can assimilate technology into herself, to the point that she can even create a flight-capable facsimile of the Anti-Art Attachment.
- Good Thing You Can Heal: She's the one who's sliced in half by Salome to demonstrate how dangerous the latter is.
- Healing Factor: Her plant-like physiology means that she can recover from being sliced in half with no ill effects.
- Plant Person: She has flowers growing from her back and the sides of her head, and even her cells are closer to a plant's than an animal's. She can manipulate plants, such as controlling vines to ensnare an enemy.
ElzaA member of the Kamisato Faction. She is a magician who channels her power through coins.
- Cast from Money: She can control copper coins to act as a projectile or as a shield to block attacks.
- Going Commando: Apparently, she wasn't wearing any underwear during the incident that eventually led to her falling in love with Kakeru.
- Japanese Delinquents: Presents herself as one, though her personality doesn't really fit the trope.
A member of the Kamisato Faction and Kakeru's non-blood related younger sister. Salome is a mass murderer and a powerful magician that uses Celtic-based sacrifice magic. Though considered very troublesome by the rest of the faction due to her personality, she's also the strongest fighter of the group.
- BrotherSister Incest: Obviously has feelings for Kakeru, her non-blood related brother.
- Does Not Like Shoes: She walks everywhere barefoot.
- Feel No Pain: Due to her peculiar body structure, Salome doesn't feel pain.
- Immortality: Salome has replaced her original body with an artificial one using Internal Offering, which has given her superhuman strength and speed. She is essentially a flesh cyborg; she doesn't bleed or feel pain and she can continue moving and talking while ignoring any wound she suffers. She can even survive as just a head.
- Increasingly Lethal Enemy: Salome's main magic, External Offering, allows her to absorb the power of any weapon she can destroy with her own body to increase her own strength by offering the destroyed weapon to sea god Manannán. Since this gains of power stack, she can destroy incrementally stronger weapons and continuously grow in power in the right conditions. However, she will lose all accumulated strength if three minutes pass without her destroying any weapon, breaking the chain.
- Not Blood Siblings: She and Kakeru are not related, she lived with his family and they grew up together.
- One-Man Army: Considered the strongest fighter of the faction who could walk right into and single-handedly destroy the White House.
- Only Sane Man: Despite her self-admitted mental issues she's also one of the few reasonable members of the faction that can see that Kakeru is being warped by World Rejecter and his large harem, leading him to take more morally dubious choices in his conflict with Touma. She calls him out in this and joins forces with Touma to try and return him to normal.Salome: It wasn't Kamijou Touma or the Magic Gods that messed up Kamisato Kakeru. Hamazura, Misaka, and the #1. Also an Academy City airport and bank, I guess. I tried a few different people, but none of them felt right! I mean, the Kamijou Faction has done nothing wrong!! The source of it all is that goddamn stupid harem you call the Kamisato Faction. These idiots are in heat year-round and have even thrown out the term "self-responsibility".
- Serial Killer: Salome is a known and prolific mass murderer. However, she refuses to go after defenseless people, considering it "too boring", and views herself as a hunter/predator looking for a challenge, which is why she goes after more challenging prey like criminals and evil end-of-the-world cults.
- Token Evil Teammate: She's definitely the craziest member of the faction and the one who has committed the more crimes. She still ends up cooperating with Touma against her brother and the rest of his faction.
- Vapor Wear: Her outfit is translucent and she doesn't wear underwear.
- Yandere: She states that she'll do anything for Kakeru, including murder. She is also antagonistic to the rest of the Kamisato faction. When she comes up to the conclusion that the harem of girls is what has messed Kakeru's character she swiftly decides killing them all will solve the problem.
A member of the Kamisato Faction and a self-proclaimed Gemstone that claims to have obtained her powers after being abducted by aliens. Actually a magician and spy of the Anglican Church sent to manipulate the faction by the Archbishop.
- Alien Abduction: Claims her powers are the result of this, though Kakeru and the rest of the faction are skeptical. They aren't, as she's a magician.
- Demonic Possession: Temporarily by Coronzon, but freed by Aleister.
- The Mole: For the Anglican Church.
- Walking Swimsuit Scene: Wears a swimsuit under her clothes.
Luca ToyamaA member of the Kamisato Faction and pirate girl magician that uses Voodoo-based magic to manipulate her subjective time.
- Fountain of Youth: Since her magic gives her control over her subjective time, she can make herself as young as she wants. She is seen making herself a child of 7-10 years of age to dodge incoming attacks and to trick other people.
- Mundane Utility: Luca's ability to manipulate her own subjective time means she can simply freely skip any time she doesn't want her body to experience. This includes drunkenness, hangovers and her period, the latter use creating some jealousy in other members of the faction.
- The Musketeer: Carries a cutlass and a musket as weapons.
- Nice Hat: Wears a tricorne with a blue feather.
- Overnight Age-Up: Since her magic gives her controls over her subjective time, she can make herself as old as she wants, and is seen making herself college-age.
- Pirate Girl: Her motif.
- Shapeshifting Excludes Clothing: Her time magic only affects her body.
- Walking Swimsuit Scene: Depicted as only wearing a bikini under her sailor's coat, due to the heat wave caused by the Kamisato Faction during the Element invasion. Her earlier description as one of the nameless members in the faction prior to said event indicates she wears normal clothes on regular occasions.
Maya GoryouA member of the Kamisato Faction and a ghost girl.
- Cute Ghost Girl: Her motif.
- Ghost Amnesia: Maya can't remember anything of her previous life. In fact, at first she couldn't even remember her own name. She doesn't want to recover her memories, and she's happy 'living' as a ghost thanks to Kakeru's support.
- Hitodama Light: Maya uses Censers, small drones shaped like crane flies that emit a pale phosphorescence like will-o-the-wisps, to create a moving artificial haunted location to support her existence, allowing her to freely move around and interact with others. Because of said phosphorescence, the Censers looks like hitodama floating around her.
- Our Ghosts Are Different: Maya is a ghost, though not even her knows exactly what a ghost or a soul is. She lacks a physical body, and can only be seen in special locations known as haunted locations. She pictures herself as something like a smell. If she rubs the smell of her life onto something else before it fades with time, she can continue living on. But if she cannot produce the smell, it would be the end for her.
- The Sleepless: As a ghost without a physical body, Maya doesn't need to sleep.
- Voluntary Shapeshifting: When using her own scent to support her existence Maya can freely change her own shape, including turning into a giant version of herself and into a large Will-o'-the-Wisp.
- Will-o'-the-Wisp: Her Censers drones project this image, and she can turn into one.
Olivia SawaiA member of the Kamisato Faction and a cosplay girl.
- Cosplay Otaku Girl: Olivia is a cosplay girl that can perfectly reproduce all the gimmicks of the character she's cosplaying like a magic wand or a laser blade through either magic or science.
- Magical Girl: Her current cosplay is the original Magical Powered Kanamin, the protagonist of the magical girl anime that Index likes.
- Method Acting: The other girls of the Kamisato faction comment that Olivia is so dedicated to cosplaying, if the character she chose to cosplay had an arm on a sling she would break her own bones with a hammer for realism.
- Reality Ensues: Olivia might as well be the best copslayer in the world given her dedication and ability to perfectly imitate a character, but the gimmicks she reproduces are very dangerous (as one of the combat members of the faction she's noted to have enough firepower to single-handedly break open a bank vault), so she's constantly kicked out of events.
- Rocket Ride: The Magical Powered Kanamin wand she carries has a jet engine, allowing her to fly around by riding it.
- Voice Changeling: Olivia is noted to use the same high-pitched voice of the original Magical Powered Kanamin, which is rumored not even the original voice actress can reproduce any longer.
