Organizations with their own pages
Another organization in Academy City's dark side which answers directly to Aleister. Their goal seems to have been to stop the rebellion of the other two organizations, SCHOOL and BLOCK.
The elderly man who leads MEMBER. A loyal dog of Aleister Crowley. He possesses an item called "Mimosa", bits of reflective alloy which respond differently to specific frequencies, and is known to dissolve through flesh.
- Measuring the Marigolds: He sees things as beautiful because of the formulas underlying them.
- Nanomachines: His main weapon. It doesn't work on Teitoku, who (at the time) had obtained a tool that allowed him to detect nano-scale objects.
- Only Known By Their Nickname: He's only referred to as "Professor".
- Secret Keeper: He knows that Xochitl is actually a magician.
A hacker who works for MEMBER. He supports the professor from a shelter known as "Summer Resort" with his remote controlled animal robots. He also makes an appearance in the Railgun version of the Daihesesai when he discreetly drugs Misaka 10032 (possibly mistaking her for Mikoto) with a robotic mosquito. He also leads his low level school to an impressive victory over Tokiwadai in the balloon hunter contest handing them their first loss.
- Badass Normal: Has no known ability.
- Combat Pragmatist: Won't hesitate to have multiple robots gang up on a single opponent.
- The Cracker
- Left for Dead: The last time we saw him the underground shelter he was using is flooded (presumably by SCHOOL), leaving him trapped and with no method of escape.
- Mission Control: Often assumes this role.
- The Smart Guy
- Robot Master: He uses a variety of robots modelled after animals: Type: Great Danes for tracking and combat, Type: Mosquito for covert surveillance and sneak attacks, and the massive Type: Mantis for heavy combat.
- The Worf Effect: When he unveils his Type: Mantis, he's confident that it can make short work of its targets - then it gets destroyed instantly by Mikoto.
- All Men Are Perverts: In his cameo in Railgun, he's planning on buying cards that will allow him to have Erotic Dreams involving celebrities.
- Combat Pragmatist: He makes full use of his ability to teleport behind people, and is also willing to use innocent civilians as human shields.
- In-Series Nickname: Accelerator dubs him "Kill Point" after seeing his ability, and the Professor refers to him the same way afterwards.
- Teleportation: He can teleport himself, but only directly behind another person. This is because he lacks the calculating ability needed for normal teleportation, so he has to use another person as a reference.
The Corpse Specialist
A magician from the Return of the Winged One, punished by being ordered to infiltrate Academy City and kill Etzali. The Professor seems to be aware that she is a magician. She was also a protagonist in Railgun SS.
- Barely-There Swimwear: In the Railgun SS. When she convinces Saten to get her a bikini to move around unnoticed in, she gives her something that Kuroko would wear...In fact, see for yourself. Her measurements are "84, 58, 81" for the record.
- Big Damn Heroes: Twice. She saved Saten from being killed by Olive Holiday and being crushed in the Railgun SS.
- Cool Airship: The Mixcoatl.
- Cool Sword: "Macuahuitl", a sword that's used to saw through human bodies.
- Awesome but Impractical: Etzali makes use of the fact that a sword used to saw through human bodies isn't well suited for slashing through them directly.
- Hammerspace: One of her abilities.
- Master of Disguise: Like Etzali, she can use the skin of others to disguise herself.
- Rewarded as a Traitor Deserves: After going against her superior's orders by teaming up with Mikoto in the Railgun SS.
- Body Horror: A grimoire was forcefully pushed onto her body, turning a huge portion of her body to dust and was replaced by artificial tissue.
- Senpai Kouhai: A junior to Etzali.
- Necromancer: Her original magic centered around speaking with the dead
- Used to Be a Sweet Kid: Etzali described her as afraid of violence, however when the Grimoire was implanted...
- Wild Card
MEMBER's liasion with the Board of Directors. She does not appear with the rest of MEMBER in the original series, instead appearing during the Daihaseisai Arc in Railgun.
- Evil Cannot Comprehend Good: She considers people who live peaceful lives as "oddities", due to her own experiences.
- Freudian Excuse: The reason she turned to the dark side was because Academy City created Dolly (the first clone of Mikoto) and treated her as no more than an expendable tool. Dolly was Mitori's only friend, and she vowed to destroy Academy City for this.
- Genki Girl: A darker example than normal. She behaves like this regardless of the situation, due to being accustomed to the dark side of Academy City.
- Girlish Pigtails
- Heel Face Turn: After her and Gensei's plan fails, Misaki takes her to Full-Tuning, another Sister who has all of Dolly's memories. Mitori is able to let go of her hatred and is now one of Misaki's allies.
- Power of Hate: She runs on this, hating Academy City for what happened to Dolly. It's the reason why Gensei Kihara recruits her to his cause.
- Remote Body: Her Level 4 esper ability, Liquid Shadow, allows her to control liquids with a specific gravity of at least 20. She uses this to animate a body of liquid metal, essentially a drone version of the T-1000. The body can be shaped freely and has the sense of hearing and touch, but not sight (compensated for by having it carry a camera).
- Stepford Smiler: Even as a child, she forced herself to smile to ensure that the scientists studying her would underestimate her.
An organization whose original goal was to check up on the cooperation of friendly institutions outside of Academy City. However, they lost trust in Academy City and decided to rebel. They planned to kill Aleister Crowley by forcing Awaki Musujime to cooperate with them.
The leader of BLOCK. He creates a complicated plan by using SCHOOL, GROUP and several mercenaries in order to divert Aleister's attention while they infiltrate the Windowless Building. He is eventually taken out by one of his own members who disapproves of his tactics.
A muscular woman formerly from Antiskill. She doesn't endorse unnecessary violence and ruthless tactics, leading to her taking BLOCK's plans into her own hands and force Awaki into helping them while using their own version of Capacity Down.
An organisation formed in the aftermath of World War III, to counter the burgeoning threat of GREMLIN. They are effectively dissolved at the end of New Testament Volume 1, with their leaders captured.
Umidori Kuroyoru is a sadistic girl and a remnant of the Dark May project who leads the mysterious Freshmen.
- Abusive Parents: Played for laughs, Misaka Worst "adopted" her. And what does she do first? She constanly loves taking control of her like some puppet master, and makes her cry. Yeah...some mother of the year.
- Anti-Hero: In NT Volume 3.
- Awesomeness By Analysis: Uses Kihara Amata's vector values and inputs them into her nitrogen lances, making Accelerator's vector shield useless.
- Ax Crazy: Oh yeah, big time.
- Bare Your Midriff
- Break the Haughty: Misaka Worst torments her so hard she cries.
- Brick Joke: Touma invokes the possibility of her having cyborg cat ears underneath the raincoat she always wears. She denies this. Cue Misaka Worst barging in later on, saying she found "optional parts," specifically cat ears and cat paws gloves. Kuroyoru screeches when she hears this.
- Catgirl: New Testament Volume 2 foreshadowed this heavily.
Umidori: There isn’t going to be some strange development where it turns out I always wear my hood in order to hide cat ears!!
- The inevitable happened in New Testament Volume 3: Misaka Worst has "adopted" her and calls her Kuronyan.
- Card-Carrying Villain: At any chance she gets, she insists that she's a villain that loves the darkness and destruction that's out to destroy the Graduates (Accelerator, ITEM, Hamazura to name a few).
- Cry Cute: In New Testament Volume 3 when Misaka Worst takes her teasing a little too far:
- Cyborg: She uses this to augment her power. Since "Bomber Lance" is fired from palms, she attaches hundreds of mini-arms to her back. She can also detach pieces of her body like her arms. Apparently the yearly surgeries to maintain this ain't worth it, according to her.
- And it doesn't help that Misaka Worst is an electromaster that can completely dominate her because of this.
- Dark Action Girl: Just look at her. Nothing is left to be said.
- Dark and Troubled Past
- Emotionless Girl: When she's not being Ax Crazy or a Jerkass, she seems to be this.
- Shiage can't seem to understand why she and Misaka Worst were so bored when their lives (as well as the people) were in danger.
- Enfant Terrible/Troubling Unchildlike Behaviour: Merely 12, and she's indulges in death and destruction. Most likely due to adapting to Accelerator's thought patterns.
- Evil Counterpart: To Saiai.
- Evil Feels Good: She gives Accelerator a small speech about it too.
- Even Evil Has Standards: Invoked. In her own words, after being locked up in Touma's bathroom:
Umidori: And even as a member of the darkness, confining a twelve-year-old kid in the bathroom and removing both her arms seems really fucking twisted to me!!
- Expy: She's Azusa from K-On!, except she's a psychopath.
- Foe Yay / Les Yay: Her jealousy of Saiai, the Honor Student, can seem like this if you squint. Now, unfortunately for her, Misaka Worst has taken a liking to her.
- Kouhai: She was the kouhai of Saiai Kinuhata during the Dark May project -- her as the rebellious punk.
- Meaningful Name: "Kuroyoru" can be roughly translated as "Black Night", and "Umidori" can be translated as "dolphin". Roughly, her name means "Dolphin of the Dark Night".
- Mood Whiplash: Gets this hard when she goes on a villain tirade and tries to kill Touma, only to have him casually dismiss her and start talking about cyborg cat ears!
- Multi-Armed and Dangerous: Her power allows her to project lances of compressed nitrogen from her palms. Because she only has two palms, normally she can only produce two lances. The solution to the problem...modify herself with cyborg arms to give herself lots of palms. Problem solved.
- Not So Different: Accelerator gets a little creeped out by the fact that she's quite literally a mirror image of his old self. Literally, as a product of the Dark May project, she has Accelerator's offensive cognitive patterns in her brain. Kuroyoru happily lets her psyche be affected by the old Accelerator's thought patterns -- unlike Saiai, who more or less controls herself.
- Odd Action Duo: Her and Misaka Worst.
Misaka Worst: How about we join forces as the villain girl combo?
- Precision F-Strike: Her first meeting with Accelerator.
Umidori: There was something I wanted to ask you if I ever met you. I had actually completely forgotten about it, but I remembered it when I saw your face. So I guess I’ll ask you now.
- Suspiciously Specific Denial: She does not have cyborg cat ears! STOP ASKING!
- Taking You with Me: Tries to kill Fremea in a last ditch effort. Thankfully, a certain someone stops her. It's Touma.
- There Is No Kill Like Overkill: Her cyborg arms allows her to spam her ability.
- Villain Ball: She thinks just like the reckless, prideful, and A God Am I over-confident Accelerator from Volume 3. When she fights Accelerator, the simple fact that he sidesteps her attack -- completely diverting from his original self who would've stood head-on, and thus what Kuroyoru thinks -- ends up completely bewildering her, leading to her defeat.
- Yin-Yang Bomb: After listening to Leivinia Birdway's lesson about magic, she develops a technique where she channels AIM into her cyborg parts, then attempts to cast a simple spell. The AIM and mana react and trigger an explosion and mini-earthquake. Doing this damages her cyborg parts, but leaves the rest of her relatively intact.
A member of the Freshmen who specializes in using powered suits.
- Bishonen: Underneath his armor, he's described as handsome.
- Powered Armor: His usual armor is a suit called Life Armor, which is covered in plating like an armadillo's. It's durable enough to let him jump out of a vehicle moving at over 500 km/h, and can also grant him any knowledge or skills he needs (such as martial arts skills). If he's injured, the Life Armor is shed to reveal the Emergency suit underneath, which can reshape itself to act as a sort of cast for broken bones or to create weapons.
- Mini-Mecha: He has a number of larger powered suits, which he uses while wearing the Life Armor.
- The Enemy Blaster is five meters tall and stands on eight crab-like legs. It's armed with a machine gun and smoothbore cannon, and is meant for open combat.
- The Bee Launcher is humanoid in shape, with long poles extending from its back that hold Edge Bees. These are remotely-controlled drones that fly using central propellers and have chainsaws on their outer edges. The chainsaws allow them to cut through walls or to grab objects and throw them.
- The Highway Cheetah is quadrupedal and emits a volatile oil from its feet as lubricant, allowing it to slide at high speeds.
- The FIVE_OVER Modelcase "Railgun" is the most powerful suit by a considerable margin. Shaped like a giant mantis, its forelegs are armed with two Gatling Railguns. A sustained barrage from these can destroy almost anything.
A mercenary hired by Thomas Platinaburg in order to dispose of Accelerator. A friend of Sunazara Chimitsu.
- Badass Normal: Takes on Kinuhata Saiai without using any powers. Being a former Antiskill trainee, she knows how to suppress espers without using lethal force.
- Awesomeness By Analysis: Her time in Antiskill training allows her to analyze esper powers and their workings.
- Friendly Sniper: in contrast to Sunazara, who says that her tactics are an outrage to assassins.
- Genre Savvy: Shows up to her meeting with Thomas Platinumburg already well aware of his attempts to rig Sunazara's body with a device to blackmail her with. She quickly reveals that she has already removed said device and implants it into Thomas instead.
- Improbable Aiming Skills: She's good enough to take out people non-lethally with a gun, by ricocheting the bullets or firing through obstacles.
- Kick the Son of a Bitch: Kills Thomas Platinaburg after she finds out that he was tampering with Sunazara's body with machines in order to force Stephanie to cooperate.
- Mini-Mecha: She uses one in NT Volume 12, called a Power Lifter.
- Revenge: Decides to avenge Sunazara by hunting down Saiai Kinuhata.
- Technical Pacifist: Her fighting style is designed so that she can apply only the necessary amount of force without being lethal.
- There Is No Kill Like Overkill: She originally thought it was best to use a missile launcher then a sniper rifle to assassinate. Proven otherwise because such overkill make harder to prove the death.
- Well-Intentioned Extremist: She only became a mercenary in order to protect the peace that she used to live in.
The main antagonist of New Testament Volume 11, a rogue agent who seizes assets to form her own organization.
- Animal Motif: Her surname means "honeypot ant", and she describes herself as the ant to Misaki's bee. She's also called a samurai ant (a species of slave-making ant) by Noukan Kihara, in reference to her stealing the resources of other organizations to make her own.
- Bungled Suicide: After learning that her lack of power was due to favoritism by Academy City, she tried to drown herself. It's not specified how she survived.
- Combat Pragmatist: Lacking the incredible power of Misaki, she makes use of several pieces of technology to compensate. At one point, she pretends to be affected by Misaki's power, only to attack when Misaki least expects it.
- Fat Suit: She wears one that makes her look like a morbidly-obese version of Misaki. It's actually the FIVE_OVER Outsider disguised as a fat suit.
- Foil: To Misaki. Both are telepaths, with Ayu being weaker because she was deemed less promising by the Parameter List and hence received fewer resources. They both have a group of followers, but Ayu gathered hers through fear and mind control while Misaki gathered hers with kindness. Both of them interacted with Touma in the past, but while he saved Misaki's life, he failed to reach Ayu in time to stop her attempted suicide. Finally, they're both aware of Touma's memory loss and have been forgotten by him, but while Ayu has the potential to form a new relationship with him, Misaki can never be with him since he can never form new memories of her. The similarities and differences are lampshaded by both characters and by the author.
- It's Personal: Her entire motivation is to get revenge on Misaki for (unknowingly) stealing Touma from her.
- Magic Feather: Similar to Misaki, she directs her power through a technological device. Ayu uses smartphone cameras for this.
- Master of Illusion: Using the FIVE_OVER Outsider, she's able to disguise people and objects, even on the scale of entire buildings. She uses this to trick Misaki into thinking that her memories have been tampered with, by covering an entire geothermal plant so that it looks completely different from Misaki's memories.
- Meaningful Name: "Ayu" means "love and joy" and "Mitsuari" means "honeypot ant".
- Taken for Granite: A non-stone variation. One application of the FIVE_OVER Outsider is to create a giant eyeball, which draws on various mythological motifs to induce paralysis in anyone who sees it. This is explicitly compared to a gorgon's gaze by Ayu.
- Telepathy: Mental Stinger, essentially a Level 3 version of Mental Out. It functions via manipulating moisture in the brain to affect nerve impulses indirectly.
- Villainous Breakdown: When Touma arrives despite not remembering either of the girls, Ayu can't believe this has happened and loses control of her power.
- Walking Spoiler: It's impossible to describe her at all without bringing up her relationships with Touma and Misaki.
- Walking Wasteland: If she loses control of her power, she starts affecting moisture on a macroscopic scale, essentially freeze-drying her surroundings.
