Characters / A Certain Magical Index Gremlin

Go To

A new organization that emerged from the remains of WWIII that was formally introduced in New Testament 2, who are so far the main antagonists of New Testament. They are a group of Sorcerers that are going against the Science Side, who are considered the victors of the war after Fiamma's defeat.

A new generation of the occult that had only started being passed down by humans once the concept of machines had been created, in that world where the winners of World War III, the Science side, had greatly spread, a type of occult that would devour it had been born.

Tropes common to the organization:

  • Attack Its Weak Point: Gremlin hates and yet fears Touma so much that they have either crafted or gathered spells specifically to use against him.
  • Colony Drop: They attempted to drop Radiosonde Castle on Academy City.
  • Evil Luddite: What they appeared to be at first, a cabal formed to fight the victor of World War III, the Science Side. It was an intentional misleading on their part.
  • Hostage Situation/I Have Your Wife: They LOVE this.
  • It's Personal: They hold Touma Kamijou responsible for losing everything during the war and have marked him. They went so far as to level mountains and rivers to change the ley lines of the planet in order to track him down.
    • Subverted as of Volume 3 of New Testament, where it is revealed in the end that the members who have a personal grudge against Touma and the Science Side are actually a front for the real GREMLIN and have no idea of the organization's true intentions. Not much has been revealed as of yet, but apparently it has something to do with Gungnir.
    • Double-subverted as of Volume 10. Othinus was apparently a mere pawn in the true GREMLIN's (composed of the Magic Gods of all the world's religions) plans to manipulate Touma's growth. Everything that happened was nothing but a trial to test Touma.
  • Meaningful Name: They called themselves GREMLIN due to the fact their magic and tactics are specifically developed to combat Touma and the Espers of Academy City, like how stories of gremlins involve the creatures disrupting technology.
  • Norse Mythology: Most of their magic and many of their names are based off this.
  • The End of the World as We Know It: They would have caused an Ice Age that could wipe out the world if they had dropped Radiosonde Castle.
  • There Is No Kill Like Overkill:
    • They were willing to cause an Ice Age in order to either destroy Academy City and the Espers, or just to track down Touma Kamijou. They even had the foresight to predict that there was a chance of him surviving it and left a message.
      • It's implied that they planned for the Colony Drop to fail just so that they could locate/determine the existence of Touma. It's remarked upon by Kaori when she's fighting Mjölnir that the enemy seems rather apathetic and isn't opposed to destroying large portions of their own weapon during the battle, which indicates that they didn't put much stock in the attack actually succeeding.
    • They triggered a volcanic eruption in Hawaii, causing untold destruction, just to use the volcano's heat to forge a replica of Gungnir.
  • You Have Outlived Your Usefulness: Tend to do this to lower henchmen after they finish their assignments.

    One-Eyed Othinus

One-Eyed Othinus is the leader of GREMLIN and currently holds the title of current Majin (Magic God). It's just Odin to friends.

  • Absolute Cleavage: Her outfit is compared to a swimsuit.
  • A God Am I:
    • "Unlike a certain failure, I am a pure magic god. If that is not enough for you to understand, my words are wasted on you. You should just give up on understanding."
    • "It may be hard to believe, but I am a god. Do you really think the great Othinus would bother to fight a puny human?"
    • Notably she still calls herself a god even after she is Brought Down to Normal.
  • Always a Bigger Fish: As of New Testament Vol 10, it is now known that, not only is she not the only Magic God, but there is also an entire organization made up of them, from all of the world's religions. They seem to be also more powerful than her, as she did not even know of their existences, allowing them to manipulate her and Touma for their own goals.
  • The Archmage: A Majin is the apex of magical power and talent.
  • Big Bad: From New Testament Vol 2 to 9.
  • Blessed with Suck/Cursed with Awesome: She has infinite potential as a Majin, however her success rate is always 50/50. While she may defeat the strongest opponents 50% of the time, she might also lose to the weakest opponents 50% of the time. She wants Gungnir to overcome this problem. Funny enough, this proves to be a formidable advantage when battling Imagine Breaker, and later, the Invisible Thing; since Touma has very bad luck, it tilts the scales in her advantage, to the point where victory is deemed miraculous.
  • Brought Down to Normal: At the end of NT Vol. 10 she is reduced to 15 centimeters tall and has too little magic to be able to use it at all.
  • Chekhov's Gun: Gungnir has been at the center of one short story, although it was a replica—what Othinus wants is the real deal.
  • The Chessmaster: Manipulates everybody, even the other members of GREMLIN.
  • Chew Toy: After she was brought down to chibi, she's this to Sphinx.
  • Deliberate Injury Gambit: When Touma manages to dodge nine arrows from her crossbow, she fires the last one through her own body to take advantage of his only blind spot. It works.
  • Deity of Human Origin: She was a human who found the means to become a Magic God.
  • Driven to Suicide: She doesn’t think she deserves to be saved because of her actions and how much Touma suffers to protect her. She uses up the last of her magic to summon her crossbow so she can keep Touma away from her while the “Turn into a Fairy” spell finishes her off. She survives the attempt thanks to the Magic Gods of True Gremlin.
  • Evil Counterpart: Touma doesn't need a reason to help people. Othinus doesn't need a reason to destroy. Their powers also revolve around misfortune.
  • Exposed to the Elements: She is completely unaffected by cold despite her outfit, and Touma remarks that she feels warm. However, in NT 10, since her powers are fading away, this is because she's dying and going numb.
  • Eyepatch of Power: Over the right eye.
  • Eye Scream: Missing an eye, as expected of Odin, and wears a patch to cover it up. Later, she pulls Gungnir out of her right eye socket. Her right eye is stored in Mimir's Well in Denmark. If it is returned to her, she will lose her powers and become human.
  • Final Boss: She is Touma’s final opponent of NT Vol. 10’s Boss Rush. Believing herself to not be worth saving, Touma has to fight his way through her crossbow attacks to try and save her before she dies from using all her remaining magic.
  • Forced to Watch: Silvia intended to do this to her by beating Touma within an inch of his life before killing him as Revenge by Proxy for what happened to Ollerus, but Ollerus himself intervenes to knock her and Brunhild out because doing that to Touma would have turned Othinus into something even worse than she was before.
  • Fun Size: As of the end of New Testament 10, she's now 15 centimeters tall, and contains such a miniscule fraction of her power that it's next to useless.
  • Heel–Face Turn: Upon realizing Touma truly understands her and being touched that he trusted her to use Imagine Breaker better than he did, she instead restores the world to the way it was, and resolves to be killed to atone for her sins. Touma then decides to save her.
  • Heel Realization: She realizes that she had been so obsessed with finding a way to return to her original world, that she had been willing to hurt and antagonize everybody, and that she had forgotten the real reason she wanted this: to find someone who understood her. Then she realizes it has been so long that she can barely even remember her original world, and that Touma's world wasn't so bad.
  • Heroic BSoD: Just mentioning Sphinx's name is enough to cause her to outright breakdown and require Touma to do everything he can to cheer her back up. Considering how fearless she is even when having to stare down other Magic Gods when she has no power of her own anymore, it's quite a Mood Whiplash.
  • Hey, You!: Even after her Heel–Face Turn and getting Brought Down to Normal, she never stops calling Touma “human”.
  • I Am Not Left-Handed: Once Touma manages to destroy Gungnir, she reveals a crossbow bigger than the planet.
  • Kneel Before Zod: Demands this of Touma at one point. Of course, he doesn't.
    Othinus: It is time you learned your place and prostrated yourself in the depths of the earth, human!!
  • Last Episode, New Character: Was mentioned by Ollerus in the last line of Volume 22.
  • Little Miss Badass: She looks like a 13-14-year-old girl.
  • Major Injury Underreaction: Is completely nonchalant about accidentally blowing off her own right arm in NT Vol. 6, since Marian is on hand to repair it. Later, she doesn't react to firing her crossbow through her own body, which automatically heals itself.
  • Manipulative Bastard: She tricked people that were loose members of GREMLIN into doing her bidding so she and her close affiliates didn't have to show themselves.
    • Taken to new heights in NT8, where it's revealed she's just been using the entirety of GREMLIN as a scapegoat while she herself completes the real Gungnir behind everyone's backs.
  • Meaningful Name: Othinus is the Latin name for Odin. It is used in the book Gesta Danorum, which tells Danish history using Norse Gods as characters.
    • Prophetic Name: Othinus symbolizes the Norse God Odin, much like Ollerus does; and from what we know, this carries over to their relationship, as that also symbolizes how Ollerus temporarily took Odin's throne—hell, Ollerus has the power of Hliðskjálf, which is the name of Odin's throne for crying out loud! But then, Odin reclaimed the throne—much like how Othinus claimed the title of Majin by stealing it from Ollerus.
  • The Mentor: Essentially becomes this for Touma after being Brought Down to Normal. She often sits on Touma's shoulder (even referring to it as her personal spot, she gets testy if someone else is using it for whatever reason) to inform him of new threats he's facing off with from the Magic Side and various different strategies. Combined with Touma's already high level of analytical skill on the battlefield, this makes them a lethal combination.
  • Morality Chain: Touma becomes this for her in NT Vol. 10. Ollerus claims that if he died from Silvia's attacks, she would become a more frightening monster than anything she had shown before.
  • Names to Run Away from Really Fast: Othinus is a Latin variant on Odin, King of the Norse Gods.
  • Necromancer: She is able to create Einherjar by inserting gold into corpses.
  • Not So Different: By the end of NT Vol 9, she realizes Touma has become her equal, a person traveling the multiverse searching for home, and the only person who truly understands her.
  • Physical God: As a Majin, the highest position next to The One Above God Fiamma attained briefly. Not only does she take on the weakened Fiamma and Ollerus, but also goes against Touma then the Invisible Thing.
  • Power Copying: After getting attacked once by Ollerus' "Turn into a Fairy" spell, Othinus immediately masters the never-before-seen technique and uses it on him.
  • Pragmatic Villainy: Destroys Dáinsleif, since the end of the world would ruin her plans.
  • Pyrrhic Villainy: In the end, Touma is simply not capable of beating her. He can't even land a single punch before she kills him. However, his dying words make her realize that her goal is entirely pointless. Sure, she can change the world back to the way it originally was, but no one understood or liked her back then anyway. She gives up, revives Touma and brings back the world she had ended before.
  • Reality Warper: The limits of her powers at its peak are mental. She is not omniscient and doesn't know how to properly revert changes that she's made. That, and reality-warpers of similar scale to her, such as the TRUE Gremlin members and Aleister Crowley.
  • Really 700 Years Old: She is not a fourteen year old girl. She just looks like one. She's actually ten thousand years old at least, but gave up her abilities when she realized that she probably hadn't fixed the world back to the way it was before she accidentally messed it up. Also, she was a bearded old guy at some point.
  • Rule of Symbolism: Represents Odin from Norse Mythology.
  • Samus Is a Girl: Many people assume a mage who symbolizes Odin would be a man. She may have been one at some point, judging by Touma piecing together what must be her backstory as she keeps trying to break his will. Later, it's used to Touma's advantage since he's trying to retrieve her eye while Othinus herself is next to powerless. Yeah, everyone wants Othinus dead, but the details of her physical appearance have been kept secret and no one would expect a little girl to be a god.
  • "Shaggy Dog" Story: Almost. NT 10 was a boss rush journey for her and Touma to retrieve her eye from Mimir's Well in Denmark to prevent her from dying as Ollerus' fairy spell starts affecting her. Touma not only gets heavily beaten up by foes and former allies alike, but in the end they never recover her eye. Subverted in a Deus ex Machina fashion as True Gremlin restored what was left of her because having her lost could affect Touma greatly. However, she hasn't turned human, and the fraction of her that was recovered was so miniscule that even though she's a Majin, her magic power is next to useless.
  • Stripperiffic: She wears about as much clothing as Mu-12. In other words, almost non-existent. The artist explained that she wears so little because of her arrogance over being so powerful. She wears no protection to flaunt the fact that enemy attacks mean nothing to her.
  • The Unfettered: Consider the Radiosonde Castle incident in which entire mountains were flattened just to track Imagine Breaker, and the fact she had her puppets make Kilauea erupt so Dvergr could use it as a forge to get closer to crafting Gungnir, and you've got a case in point. Don't even get started on the whole "theocratize the United States" plan.
    • And now consider that all of that was merely to distract people from realizing her true plan to forge Gungnir herself.
  • Unwitting Pawn: To the Magic Gods of all of the world's religions who make up the true GREMLIN. They claim she is nothing but a failed experiment and a tool they used to manipulate Touma's growth.
  • The Usurper: Stole the title of Majin from Ollerus.
    • Subverted. She was the original Majin but gave up her powers long ago. She merely took back her own title.
  • Villainous Breakdown: For the longest time, Othinus viewed Touma dispassionately and with contempt; an inferior loser not even worth mentioning. Then in NT9, her failure to break his will despite the massive Trauma Conga Line she subjects him to and him gaining the ability to predict and evade her attacks leave her completely enraged, even grinding her teeth.
  • War God: Throughout the centuries, many different cultures identified Othinus with variations of gods of war.
  • Wham Line: "These small fights are such a pain. I think I'll just end the world." She succeeds.
  • Winds of Destiny, Change: If she gains Gungnir, she will be able to control her success rate and change it to a 100% chance of victory, making her pretty much invincible.
  • Worthy Opponent: At the end of NT9, she acknowledges Touma as one. Pretty significant considering she did not see Ollerus or Fiamma of the Right as these.
  • You Can't Go Home Again: Due to seemingly warping reality multiple times, Othinus has forgotten what the world was like before the changes. Her desire to return back to that world is what is really drove her to action in the first place. Unfortunately, she can only make changes, not undo them.
  • 0% Approval Rating: Everyone hates her and her subordinates fear her. In volume ten this turns the whole world into her and Touma's enemy, even though at least one of the things she's blamed for is actually the fault of Academy City and Leivinia Birdway. If anything, her own forces were in Baggage City as peacekeepers with even the psychopath Marian attempting to keep civilians safe.


Hammer of the Thunder God

Mjölnir is a sorcerer who was at first mistaken for a spiritual item but in actuality has optimized their physical body into various forms of the hammer. Guarded Radiosonde Castle and fought with Kanzaki Kaori on even ground for a time.

  • Ambiguous Gender: Though the other members of GREMLIN tend to refer to it with female pronouns.
  • Body Horror: What Mjölnir did to his/her body for the sake of power.
  • More Dakka: Can deploy magical crossbows and flintlock pistols that fire at supersonic speeds.
  • Rule of Symbolism: Mjölnir's magic has elements of its counterpart in Norse Mythology.
  • Shapeshifter Weapon: He/She is one!
  • Shock and Awe: Mjölnir is Thor's hammer, with all the powers that represents.
  • Sinister Geometry: An enemy whose forms are all 2D shapes or basic 3d shapes like a Cylinder.
  • Super Empowering: As Thor's hammer, it can grant Thor a massive power boost via a spiritual link.
  • Talking Weapon: Can communicate by either vibrating or forming mouths along its surface.
  • Undying Loyalty: To Marian Slingeneyer, obeying her, protecting her when she is downed, and expressing concern for Marian's mental health.
  • Weaksauce Weakness: In the Toaruverse, flight spells are easy. But thanks to a certain parable from the Bible, flight-canceling spells are even easier. Mjölnir's strategy against Kanzaki revolves around keeping her from remembering that Mjölnir is a magician, not some sort of inhuman weapon. Once Kanzaki remembers that, she drops Mjölnir like a rock.


A French sorcerer of GREMLIN who first appears in New Testament 3. She uses Cinderella as the basis of her magic, which is a lot more dangerous than you might think.

  • Body Horror/And I Must Scream: At the end of New Testament 3, she was turned into a table Mjölnir style—except against her will.
    • Ollerus fixed her so she can shapeshift now.
  • Clothes Make the Superman: Most of her powers come from her dress and shoes.
  • Fountain of Youth: Because Mugino didn't use all of the powder when returning her to human form, she reconstituted as a younger girl.
  • Heart Is an Awesome Power: You would think magic based on a Rags to Riches Fairy Tale would be harmless? Not so fast.
    • Rule of Symbolism: She is very agile based on how Cinderella's fairy godmother improved her dancing. She is very fast based on the pumpkin carriage driving Cinderella around. She can remotely mutilate anyone's feet that are not the same size as hers based on the glass slipper fitting. And her weakness is of course based on how Cinderella's gifts disappear When the Clock Strikes Twelve.
  • Hour of Power: Her magic stops working at midnight or dawn, which Birdway emulated using a tanker truck... that she hit her with and set on fire to resemble a sunrise.
  • Language Barrier: Is the only character in the series so far that does not speak Japanese. Fortunately, there is often someone around who can speak French (like Mikoto) to translate.
  • Meaningful Name: Cendrillon is French for Cinderella.
  • Naked on Arrival: After she gained the ability to shapeshift, she can't take her clothes with her. In New Testament 5, she smuggles herself into Academy City by turning into a powder and mailing herself. Mugino receives the package, "cooks" her, and she returns to human form naked.
  • Revenge: What she wants against the main members of GREMLIN for the Body Horror incident. She's even willing to help Touma if that gets what she wants.
  • Unwitting Pawn: GREMLIN doesn't care about her and sees her as an expendable lackey.
  • You Have Outlived Your Usefulness: Once she was captured. Subverted that she was faking her Fate Worse than Death as part of a plot to mislead the heroes in regards to Saronia's true abilities. But then there's a Double Subversion when she ends up encountering Marian Slingeneyer. Marian states that she's a true member of GREMLIN, while all those who participated in invading Hawaii were sacrificial pawns, whose actions distracted the rest of the world from GREMLIN's true objectives in Hawaii. Marian is also the one who turned Mjölnir into a cylinder, and now intends to use those same skills on Cendrillon.

     Saronia A. Irivika

A Russian sorcerer of GREMLIN who appears as the major antagonist in in New Testament 3.

  • Caring Gardener: Inverted. She has to be a gardener to use her magic, but she's not kind, threatening children, and being all about revenge.
  • Green Thumb: Controls magical plants that have various effects like mind control or paralyzing pollen. Her magic is also concentrated in a plant hidden deep in her enclave. When Touma destroys it, her power is broken.
  • Hostage Situation/I Have Your Wife: She manipulated some people into doing her bidding by holding their children hostage.
    "It truly is frightening," the sorcerer (Saronia) whispered. "All I had to say was that I would have you tear your head apart like a frozen orange and he was ready to do it."
  • I Am Not Left-Handed: She makes people think that her power only works with Russian plants, and that a person can become immune to her powers if they can beat her in gambling, like in the myth of the Leshy. Her power works with any plant, and gambling with her is pointless.
  • Icy Blue Eyes: In keeping with her evil attitude.
  • Irony: She represents a male mythological creature. Also, she prefers to be indoors, but her power requires her to go outside and have gardening skills to be effective.
  • Kick Chick: Her fighting style specializes in kicking.
  • Revenge/Revenge Before Reason: She wants to get revenge on the nations and individuals who profited from World War 3 while Russia was torn apart, even if it means going after Olay Blueshake, GREMLIN's apparent client/sponsor in the invasion of Hawaii, and Touma.
  • Rule of Symbolism: Her ability is based off the legend of the Leshy, a male woodland spirit of Slavic mythology. The Leshy is the ruler of the forest and the king of all animals that live there, and loves gambling.
  • Unwitting Pawn: GREMLIN doesn't care about her and sees her as an expendable lackey.
  • Zettai Ryouiki: As seen in the picture.

     Marian Slingeneyer

A Dvegr, and a central member of GREMLIN.

  • Body Horror: Her human reshaping magic, used on Mjölnir and later Cendrillon. In fact her primary form of fighting revolves heavily upon this.
    • And I Must Scream: Does this to everyone she doesn't kill.
    • Bloodier and Gorier: Part of the reason she creates so much carnage is to get a psychological advantage over her opponents.
    • Cruel and Unusual Death: What she does to everyone she does kill. One example is when she fused both of a mook's hands together and turned them into a faucet. Then she turned the faucet on and let him watch helplessly as all the blood drained from his body.
  • Can't Hold Her Liquor: Cannot handle alcohol at all.
  • Cool Sword: Dáinsleif - an incredibly dangerous weapon linked to Ragnarok which Marian is forbidden from unsheathing.
    • Artifact of Doom: If the blade is unsheathed completely, it will trigger Ragnarok. Othinus eventually destroys the sword, considering it too dangerous. Marian has to use a barrier before unsheathing her second copy of the sword in her second fight with Touma to avoid affecting or destroying the world.
    • Emotion Bomb: When the blade is unsheathed slightly, it causes a foe's heart to stop out of fear of what would happen if the blade was fully unsheathed... It doesn't work on Touma, even without Imagine Breaker, because he does not fear it at all.
    • Gravity Master: The scabbard can be used to create a miniature black hole, which sucks things in until the wielder decides to release it as a powerful blade due to the pent up energy.
    • Summon Magic: Dáinsleif once unsheathed completely has the ability to summon calamities belonging to any mythology.
  • Even Evil Has Loved Ones: Morally absent or not, she didn't take Bersi AKA Kihara Kagun's death well.
  • Girlish Pigtails: Has seen in the picture.
  • Meganekko: As seen in the picture.
  • Razor Wire: Loki's Net, a magical net that can move on its own and slice through nearly anything it touches. She has to use tongs to safely handle it.
  • Rule of Symbolism: She represents the dwarves who forge the mystical tools and weapons in Norse Mythology.
  • Spontaneous Weapon Creation: Using Draupnir she can produce any magic sword or spear usable by humans.
  • Summon Magic: She's able to summon her creations using gold as a conduit.
  • Talking the Monster to Death: While fighting Touma, she gets so angry and frustrated over how well Touma is doing that she threatens to draw Dáinsleif completely and trigger Ragnarok. Touma counters that if she had the guts to do that, she would have done it immediately. Marian then realizes that she is too afraid to draw the sword.
  • Teacher/Student Romance: She taught Bersi how to use magic, and they ended up in an intimate relationship.
  • Ultimate Blacksmith: Her true role in GREMLIN. She is to help forge Gungnir with her abilities.
  • Vapor Wear: All she wears are overalls with nothing underneath.


Bersi is a sorcerer, who was once an Academy City researcher known as Kagun Kihara.

  • Badass Longcoat: Wears a coat that reaches to his ankles.
  • Badass Teacher: Was a teacher in Academy City right before he left.
  • Came Back Wrong: After his death, Othinus brought him back as one of her undead minions. He still has all his powers and memories, but he's now a Soulless Shell with no emotions who just does what is commanded of him with impersonal efficiency.
  • Crazy-Prepared: He installed a device in his neck to allow him to break free from Othinus' control after being turned undead. He's still a Soulless Shell, but he's able to protect the innocent like he wanted.
  • Death Seeker: He became this after killing an attacker manipulated by another Kihara. In New Testament Volume 4, he and Byouri Kihara take each other down in a Mutual Kill.
  • Laser Blade: His sword, Whitting, manifests as one of these.
  • Man in White: His entire attire is white.
  • Meaningful Name: His given name means "Module".
  • Near-Death Experience: His field of study when he was a researcher.
  • Rule of Symbolism: He represents Bersi, an Icelandic saga character who fought Kormak in a duel.
  • Teacher/Student Romance: Marian taught him how to use magic, and they ended up in an intimate relationship.
  • White Sheep: One of two 'Black Sheeps' of the Kihara clan. The second one is Nayuta.
  • Winds of Destiny, Change: His sword, Whitting, alters luck. This is based on its counterpart from the Icelandic saga, which creates miracles for its wielder.


One of the true members of GREMLIN who was sent to oversee the events in Baggage City.



One of the true members of GREMLIN who was sent to oversee the events in Baggage City.

  • Compelling Voice: She can give suggestions to people, who will perform the actions 100% accurately.
  • Chronic Backstabbing Disorder: She will sell out anyone to benefit or save herself.
  • Even Evil Has Standards: She is disgusted by Marian Slingeneyer performing Body Horror on people.
  • Magic Enhancement: When she controls someone, they become powerful enough to follow the order. It is noted that if it worked on herself, she could simply pump herself up until she became a Majin. Fortunately, it doesn't, and there is no way she would ever do that for somebody else.
  • Magic by Any Other Name: It is actually unknown if her power is truly magic, as such her status as a magician is disputed, but GREMLIN doesn't really care so long as she can be useful.
  • No Sense of Direction: During the invasion of Baggage City, she keeps getting lost and asking Marian for directions.
  • Rule of Symbolism: She represents Sigyn, Loki's wife from Norse Mythology.
  • What Happened to the Mouse?: Abruptly vanishes without explanation near the end of New Testament Vol 4.


Leader of GREMLIN's direct combat.

  • Always Accurate Attack: Almighty Thor always moves him into the position that will make him win, meaning his attacks will always hit his opponent.
    • Unblockable Attack: This also means he always moves into a position where he can get around his opponent’s defenses.
  • Ambiguously Gay: He's obsessed with Touma and prone to sounding... rather questionable when he's displaying it.
  • Best Friend Manual: From the moment they met he knew exactly what to say and do to get Touma to move exactly the way he wants without even needing to lie, manipulate or even hide what he's trying to do. Friendship came later. He's so good, he can get Touma to fight him for real by taking his own self being hostage even after the former was already past the vitriolic stage in their relationship.
  • Blood Knight: Relishes fighting a mighty opponent like Touma. Basically everything he did in New Testament 5 & 6 was to ensure that he would get a proper fight against Touma. He even shot himself with a handgun just to ensure that Touma and himself would start the battle with similar injuries.
  • Chronic Hero Syndrome: Deconstructed. He saves people in need, in the process gaining power, which he uses to save more people, gaining more power, and keeps repeating the cycle. Its gotten to the point where he doesn't even know if he wants power in order to save people, or saves people in order to gain more power.
  • Deer in the Headlights: When Touma tricks him into stepping in front of a train, he gets so shocked that he doesn't try to teleport or even move out of the way, and gets run over.
  • Everyone Has Standards:
    • While he's most likely a Well-Intentioned Extremist at worst, he was absolutely done with GREMLIN after what they did in Hawaii and Baggage City. He even blames himself to some extent for not noticing it in time and preventing it.
    • He LOVES fighting but hates getting innocents involved even more.
  • Foreshadowing: In an off-hand comment, Bayloupe in vol 17 essentially reveals the true abilities of Thor almost 10 volumes before his actual appearance.
  • The Gadfly: Approaches Touma as a girl and never lets him hear the end of it about his reputation with females even though he actually does know better. Also takes a crack at Mikoto later on.
  • Gender Bender: Can transform into a girl. He's so good at this that he was able to briefly fool Touma into believing that he was actually Mikoto.
    • Master Actor: Once he's transformed, you'd never be able to tell he isn't really a girl until he reveals himself.
  • Hard Work Hardly Works: He's trying to avert this. He's not a Saint, someone with the power to save the world, or a Magic God, he's just a regular magician. His goal is to reach the levels of these beings through sheer effort and hard work.
  • Honor Before Reason: In NT Vol 6, he shoots himself to make the fight even since Touma was also shot.
  • I Am Not Left-Handed: In Norse Mythology, Thor was originally a God who controlled all forms of weather, the seasons, and natural disasters, only being restricted to the function of a Lightning God later on. GREMLIN's Thor can use much more than just the Lightning God power of Thor, but tends not to unless his opponent is powerful enough to force him to. He congratulates Touma for being able to force him to use his full power.
  • Laser Blade: From his fingertips.
  • Level Grinding: Says he seeks strong opponents because he becomes more powerful and skilled with every fight, with a bigger boost the stronger the opponent.
  • Lightning Bruiser
  • Logical Weakness: While Almighty Thor can always move him to a place where he can win, his “winning” only applies to defeating his current opponent. Anything unrelated to the fight can still hurt him. Touma exploits this by luring Thor into getting hit by a train.
  • Made of Iron: He can continue fighting even after getting shot and having his wrists broken. He even shrugs off getting hit by a train.
  • Magic Knight: One of the most straightforward examples in the series.
  • No Challenge Equals No Satisfaction: After gaining the ability to Teleport Spam, he comments that being so powerful is so boring when nobody can fight back and give him a real challenge. He pays for his complacency when Touma tricks him into stepping in front of a train.
  • Not So Different/Birds of a Feather: Take away the humility from misfortune along with the block on developing supernatural abilities and add the childishly extremist nature the magicians of Index verse tend to develop, he's basically Touma if he never had the Imagine Breaker.
  • Person of Mass Destruction/One-Man Army: His speciality is war. It's gotten to the point where he can't "level up" any further without seriously fighting someone on his level...which would mean entire cities being destroyed in the process. This is the reason why he wishes to fight Touma so badly, as he can go all out without worrying about the damage due to Imagine Breaker.
  • "The Reason You Suck" Speech: Destroys TOUMA'S illusions -punch in the face and all- to snap him out of his Heroic BSoD. Also delivers a decent one to Silvia.
  • The Rival: For Touma, quote unquote ultimate "rival".
  • Rule of Symbolism: Like his name suggests, his powers are based on Thor from Norse Mythology.
  • Shock and Awe: Fitting for a mage based on Thor. However, he needs to be physically or spiritually connected to Mjölnir to use this ability.
  • Super Strength: Again, Thor based mage.
  • Take a Third Option: He IS the third option during the conflict between GREMLIN and Birdway's faction for Fraulein Kreutune where Touma has a bone to pick with both sides.
  • Teleport Spam: As Almighty Thor, he has this ability, though he clarifies that he's actually moving the world and not himself.
  • Wild Card: At the end of NT Vol 6, he defects from GREMLIN, and is now on nobody's side but his own.
  • Worthy Opponent: Constantly looking for these but Touma seems to be his favorite.
    "I can have a battle amidst such stinging tension that I have no idea who will win…and as a conflict between a ridiculously huge power and a negating power, it won't even cause that much damage!! Has there ever been a more convenient or profitable battle than this, Kamijou-chan!?"

Introduced in New Testament 8. He is one of the guardians of GREMLIN's base.
  • Actually a Doombot: He typically uses a magical copy to confront enemies from a distance.
  • Badass Boast:
    Loki: My victory was assured from the moment you set foot here.
  • Evil Old Folks: He's elderly. Though he seems polite, his opponents can tell there's nothing but malice in his heart.
  • Properly Paranoid: Remarks that he doesn't trust any of his teammates besides his leader. It pays off because Thor was really Ollerus in disguise, and Loki's trick with the artificial sky made Ollerus send his backup to the wrong place.
  • Rule of Symbolism: He represents Loki, God of Mischief, from Norse Mythology.
  • Sharp-Dressed Man: Wears a silk hat and tailcoat.
  • The Trickster: He's Loki, after all, and he's very tricky.

  • Abusive Parents: See We Have Reserves.
  • Ax-Crazy: For one thing, she laughs when Touma destroys several of her children.
  • Dark and Troubled Past: When she became pregnant, everyone around her branded her unborn child evil and marked it for destruction. She went on the run, constantly trying to keep her unborn daughter safe. Her daughter, who is aware of everything, tried to commit suicide in the womb to spare her mother, but failed. Realizing her mother would never survive on her own, she took control of her so she could use her formidable magic that her mother could not. Acting through Freyja, she took sanctuary in GREMLIN.
  • Disproportionate Retribution: When some random guy annoyed her by asking if he could borrow her cellphone, she casually killed him in broad daylight, terrifying everyone around them.
  • Fetus Terrible: She's really an innocent woman who has no knowledge of the Magic side. Her daughter from within the womb is controlling her like a puppet and is extremely intelligent and skilled in magic.
  • Heel–Face Turn: Freyja's daughter is convinced to stand down and return control to her when Touma points out that Index can perform the spell that will heal Freyja and allow her to be born safely.
  • Locked Out of the Loop: When her daughter surrenders and returns control to her, she politely asks where she is and what is going on. Everybody just shrugs and has her carried to safety.

  • Rule of Symbolism: She represents Freyja, Goddess of Fertility, from Norse Mythology.
  • Summon Magic: She can conjure up monsters at will. She also refers to them as her children and says that she draws power and material from her pregnant womb to create them, calling the process giving birth to them.
  • We Have Reserves: She doesn't care when her children are killed, because she can always give birth to another indefinitely. This philosophy is best represented by her child Hildisvíni, a massive boar that devours everything around it, even her other children, to get bigger and stronger.
  • Well-Intentioned Extremist: Her unborn daughter controlling her is only working with GREMLIN to keep her mother, the only being she cares for, safe. Touma points out that Othinus is evil, sees everyone as expendable, and will kill them as soon as their part is completed, but she claims Othinus is a savior.

  • Rule of Symbolism: She represents Hel, ruler of those who did not die a glorious death in battle, from Norse Mythology.
  • Superpower Lottery: Her power revolves around making people die.
    Hel: I can draw out causes of death from the residual information of the dead, store them in existing weapons, and swap out the causes of death. I can strangle you with a sword, drown you with a train, crush you with a blowtorch, and burn you with a handgun. That is a suitable reason to bear the name of Hel, the queen of Niflheimr who rules over the dead.
    • An Ice Person: By channeling death by freezing. She channeled it into a knife that freezes solid anything it stabs. By stabbing the ocean, she froze all the water in a 100 kilometer radius.
