Introduced in New Testament Vol. 10, this group is not to be confused with the GREMLIN organization led by Othinus. This group consists of Magic Gods, or Majins, from multiple pantheons. They have been observing Touma and Othinus' adventures from a hidden dimension, until Aleister Crowley breaks in and confronts them directly. Afterwards, they decide to get involved in the action personally. Their goal is to convince Touma to become their "scorer".
Tropes common to the group:
- Always a Bigger Fish: To Othinus and to the previously thought most powerful being of the setting Aiwass, both of which they consider failures. Unfortunately for them, they underestimate Aleister and Kakeru far too much.
- The Archmages: Majins are the apex of magical power and knowledge.
- Ascend to a Higher Plane of Existence: How they obtained their positions.
- The Bus Came Back: When Kamisato ends up being banished by World Rejector thanks to Kihara Yuiitsu's machinations, he ends up encountering the Magic Gods in the new world, who have grown content with it since they don't need to worry about destroying it with their power since it will all be fixed after enough time. They still take the time to beat him up on the principle, however, though Nephthys and Niang-Niang decide to protect him from from actually being killed in the process until he can be brought back. When Coronzon ends up shifted to the new world, she manages to escape with Nephthys and Niang-Niang piggy-backing off behind her.
- Complete Immortality: What they likely possess. That is, until Aleister removes their immortality at the end of New Testament Vol. 12.
- Crossover Cosmology: True GREMLIN is functionally this, being described as an organization that any Magic God from any religion can take part in equally, since the gremlin is a creature not associated with any religion.
- Deus ex Machina: Literally, since they are the ones responsible for bringing Othinus back at the end of New Testament Vol. 10 for fear that her loss would result in a great change in Touma.
- Does Not Know His Own Strength: They do know their strength, but they are just so powerful that they could destroy the world by just appearing, hence why they secluded themselves in their own Pocket Dimension.
- God Is Flawed: The narration describes the Magic Gods as remarkable but lacking in some way.
- Immortals Fear Death: What Aleister wants to instill in them when he strips them of their immortality in New Testament Vol. 12.
- I Need You Stronger: At the end of New Testament Vol. 10, they reveal that Touma's entire adventure with Othinus was an "experiment" of their design to manipulate Touma's growth.
- The Omniscient Council of Vagueness: Their plans and objectives are just as nebulous as Aleister's. So far, only their interest in Touma Kamijou and the Imagine Breaker have been revealed.
- Out-Gambitted: By none other than Aleister. He first broke into their sanctuary, forcing them to come down on Earth, and pretended to get angry enough to fight them. Their battle allowed him to figure out their "parameters", and plant new ones inside them. When they weakened themselves to enter the world, he used their own spell against them, stripping them of their immortality. He even goes as far as proclaim that they are no longer a threat to him.
- Outside-Context Problem: For the majority of the cast at least. Up until now, the concept of Magic God in the Magic Side was just that, a concept, with only Index and Ollerus coming close to achieving it. Then Othinus made her appearance, and showed that there was far more to Majins than what had been speculated. Yet, she herself was not aware of the existence of True GREMLIN. The only characters who seem to know of their presence are Aleister, Kihara Noukan, St. Germain (that is, if he is not lying), and Lola Stuart.
- Phantom Zone: True GREMLIN's members inhabit in a hidden Pocket Dimension, where Othinus even at full power could not detect, and which served as a sanctuary separate from the rest of the world until Aleister broke through and cast them down.
- Physical Gods: As Majins, with some of them actual gods in mythologies.
- Powers That Be: They seem to be this for the To Aru universe.
- Reality Warper: Their standard power as Magic Gods.
- Society of Immortals: All the members are immortal.
- We Hardly Knew Ye: Despite a considerable amount of build-up, they get to do relatively little before NT Vol 13, which sees High Priest get killed off, with Niang-Niang and Nephthys getting exiled from the normal world not long afterwards by Kamisato. A duplicate of Nephthys gets to stay for the following volume and she gets some backstory, but ultimately dies by the end.
- Well-Intentioned Extremist:
- The Magic Gods do not have any ill intentions towards the world or humanity, and would very much prefer to just live in their hidden Phase without being bothered or bothering anyone. However, they are aware that even their unconscious power and wishes can affect the outside world. As a group they might not be able to reach a conclusion on what to do, and as Magic Gods they might have different values than humans. Thus, they want a "scorer", a regular human who negotiates with them and gives them an outside perspective on how their influence affects the world and how to regulate any distortions they cause. In exchange of giving them peace of mind, the scorer would get their personal wishes and prayers granted by the group. However, they are willing to destroy any obstacle in their way and view any human other than their scorer as expendable. They're also not above trying to force their scorer candidate into accepting the position by threatening those close to them.
- This desire to keep their powers from damaging the world is also why they don't really mind being forced into their ideal world by Kamisato's World Rejector, as thanks to the properties of this world they can use their full unrestrained power and any and all damage will be repaired, solving both of their desires at once. That's not to say they don't take the chance to kick the shit out of him on principle when he shows up there himself, however.
A Majin from Japanese Buddhism. Prior to becoming a Majin, he was a regular Buddhist priest who tried to become a Buddha via self-mummification in order to save all humans.
- Character Death: Before he can complete his Colony Drop plan, Noukan Kihara kills him.
- Cloudcuckoolander: According to the others, he has a habit of rapidly changing his opinions mid-sentence without noticing. He invites Touma to have a talk and negotiate with him by sending him what looks like a love letter calling him to the school roof. Once Touma gets there he decides to briefly mess with him by telling him how one of his classmates, who is a nameless recurrent background character in the novel illustrations, is something called 'the Observer' that can read minds and is watching over and collecting information about him and how about the world is nothing but a story from her point of view, only to reveal that he's kidding just as Touma starts to get very worried by the idea.
- Colony Drop: As a last ditch effort, he seizes control of the Arrowhead Comet and tries to destroy Academy City with it.
- Combat Sadomasochist: After losing most of his powers High Priest is actually able to feel some pain when Touma knocks him off a roof, which greatly excites him as it's something he hasn't felt in a long time, musing to himself he should probably thank Aleister for the opportunity.
- Dishing Out Dirt: He can create giant hands of mud, sense where someone is if they are in contact with the ground, remove dirt from underground to cause a city-wide collapse, and even seize control of the Arrowhead Comet.
- Expy: The artist said he's one of Saint Hakushin from InuYasha and Zouken Matou from Fate/stay night.
- Enlightened Antagonist: Averted, despite representing Buddhism. The narration makes clear that he has not, in fact, achieved enlightenment.
- Evil Laugh: "Uho hoi☆".
- Faux Affably Evil: He only pretends to be kind because he looks down on people.
- Irony: Despite his old and decrepit appearance High Priest is actually considered to be pretty young by the standards of other Magic Gods like Nephthys and Niang-Niang, who are more than 4000 years old.
- Mummy: Back when he was human, he mummified himself alive in an attempt to achieve enlightenment.
- Rule of Symbolism: His gold sword, golden ornaments and elaborate purple robe with a flaming-like collar are based on the accessories of the Buddhist deity Acala, and are part of the sabotage his attempt to become a Buddha suffered, as being buried with such treasures painted him as someone unable to abandon his desires.
- Sadist: He enjoys tormenting the weak, though he hides it.
- Smug Super: It is said he looks down on others and pretends to be kind when judging them.
- Then Let Me Be Evil: High Priest was a regular Buddhist priest who decided to perform self-mummification and become a Buddha in a single lifetime in order to save all people. His attempt was flawless and he should have been successful, but he was sabotaged by an opposing faction and thus failed to achieve enlightenment, becoming a Magic God instead. Upon realizing that the world had rejected him the High Priest chose to become the pathetic, sin-filled priest the opposing faction had painted him to be.
- A Twinkle in the Sky: Touma and Mikoto temporarily get rid of him by launching him into space with a mass driver, though he starts to return to Earth using the Arrowhead Comet.
- Underestimating Badassery: When Mikoto shows up to help Touma, he mocks her and says she's so weak compared to a Majin that her presence will not change anything. Needless to say, he's wrong.
- We Can Rule Together: He tries to tempt Touma into becoming GREMLIN's scorer. When Touma refuses, he starts trying to destroy Academy City.
- Worthy Opponent: High Priest is impressed and excited by how Touma immediately refuses to become Gremlin's scorer, claiming that's exactly why he's a perfect choice for the position. He's also bored and dissapointed by how Touma doesn't try to fight him alone using Imagine Breaker and instead chooses to run away and use petty tricks with the help of Misaka Mikoto.
A Majin from the Egyptian pantheon. Nephthys is a Majin born out of the collection of hundreds, if not thousands, of slaves buried alive with their pharaoh putting together every small piece of magic knowledge they knew and had access to in the pyramid.
- Berserk Button: Forced sacrifices, and given that she was born from a collection of servants buried alive with a pharaoh, this shouldn't surprise anybody. She even once wiped out an entire Egyptian magic faction because they were going to ritually kill a young girl as part of an experiment to prove the existence of Heaven.
- The Bus Came Back: When Coronzon escapes the new world, Nephthys tags along with Niang-Niang, where they end up teaming up with Shiage.
- Enemy Mine: She offered to help Touma and Mikoto against High Priest when he went berserk and tried to destroy Academy City. Touma accepted some advice on High Priest's nature and powers. Later, she begs for Touma's help against Kakeru Kamisato, pointing out that if this man is targeting gods, he'll eventually come for Othinus unless he is stopped.
- Eye Colour Change: She changes the color of her eyes on a whim.
- Facial Markings: Has green teardrop marks under her eyes.
- Intrigued by Humanity: Though she looks down on humans, she is also amazed by their passions and dreams that allowed them to do things like space travel.
- Make Me Wanna Shout: She can emit a shrill cry that can make things vibrate until they disintegrate.
- Mystical White Hair: She has silvery hair and is a goddess.
- Organ Dodge: Just like a real mummy, her organs are stored outside of her body, so they can't be harmed by attacking her directly.
- Pet the Dog: Though she could still be considered an evil god and doesn't try to stop the other Majin from killing humans, due to her origins and type of divinity Nephthys is the Majin that empathizes most with humans out of the entire group. In the past she helped save an innocent girl from becoming a sacrifice as part of a magic experiment, and the remnant of her body left on Earth even decided to help save Patricia Birdway's life by sacrificing her own existence out of a simple desire to "do something godlike" before dissappearing.
- Really 700 Years Old: She has been alive for more than 4000 years.
- Rule of Symbolism: She represents Nephthys, the protector of mummies, from Egyptian Mythology.
- Seductive Mummy: She's an undead Egyptian girl with Stripperifically placed mummy bandages.
- Smug Super: She looks down on Othinus for being weaker than her.
- Soul Jar: The fact that her organs are outside of her body is the reason she was able to survive World Rejecter.
- Stripperific: All she wears are strategically placed mummy bandages.
- Underboobs: Has these thanks to the way her bandages are worn as shown in the image.
- Vapor Wear: Her bandages clearly show she isn't wearing any underwear.
A Majin from the Chinese pantheon. Niang-Niang voluntarily took her own life to strip away the impurity of a worldly life, becoming a Xian.
- The Bus Came Back: When Coronzon escapes the new world, Niang-Niang tags along with Nephthys, where they end up teaming up with Shiage.
- Cleavage Window: Her qipao has a heart-shaped cutout, which can be seen in her picture.
- Enemy Mine: She offered to help Touma and Mikoto against High Priest when he went berserk and tried to destroy Academy City. Touma accepted some advice on High Priest's nature and powers.
- Expy: The artist said she's one of Hsien-Ko from Darkstalkers.
- Genki Girl: She is very cheerful and playful. Her lines use (☆) as terminal punctuation to illustrate this.
- Going Commando: She isn't wearing panties.
- Playing with Fire: Niang-Niang can surround her weapons with fire and shoot flames from her sleeves.
- Qipao: Wears a short one that exposes her legs up to her hip.
- Really 700 Years Old: She has been alive for more than 4000 years.
- The Resenter: She does not like Othinus for being allowed to roam the human world freely while she had to stay in another dimension.
- Rule of Symbolism: She represents the Shijie-Xian brand of immortals from Chinese Mythology.
- Shapeshifter Weapon: She can make her fingertips change into various weapons, called Pao-Pei, each having a different effect. These range from classical weapons such as swords and spears to things like chainsaws.
- The Worf Effect: She is effortlessly defeated and exiled by Kakeru Kamisato to demonstrate his World Rejecter power.
A Majin from the Vodoo pantheon.
- Jack-of-All-Trades: Since Voodoo actively draws in from a great number of cultures, Zombie has an affinity for almost any type of magic, which allowed her to quickly develop a spell to allow her and the other Magic Gods to safely enter and interact with the world outside their hidden phase.
- Scary Stitches: Her entire body is covered in stitches.
- The Worf Effect: She is defeated and killed by Noukan Kihara to demonstrate the power of the Anti-Art Attachment.
A Majin from the Greek pantheon, Chimera is described as a narcissistic that has completely left the category of "human" in her quest to improve her beauty.
- Brown Note: Her level of beauty has long surpassed human limits. Just trying to look at her caused Kakeru pain and made his vision explode with psychedelic colors. Her voice and scent are similarly incomprehensible and harmful to regular humans, who can be driven mad or even die by her. Other Majin are not affected.
- Starfish Language: Neither Kakeru nor the reader can understand Chimera's words, her voice is heard by Kakeru as an unstable and high-pitched sound like metal scraping together and her words are rendered as gibberish in the text.
- World's Most Beautiful Woman: In her quest to increase her own beauty, Chimera reached the limit to beauty one can obtain by polishing the human body. Not content with that, she started taking in elements and structures from other creatures.
A Majin from the Celtic pantheon. The same king of gods spoken of in Celtic tradition.
- Artificial Limbs: His left arm is made of silver, leading to the epithet Airgetlám (Silver hand/arm).
- Pest Controller: To fight Nuada uses the Darbh-Daol, maggot-like white bugs with no fangs or legs that ate from his divine flesh by sneaking into the gap between his silver arm and his wound. He controls a gigantic swarm of Darbh-Daol, billions or trillions of them, which he shapes into various gigantic objects related to gambling such as dice, cards, coins or a roulette wheel. This is because Nuada goes out of his way to use tools not found on his legends.
- Tribal Face Paint: His entire body is covered in war paint tattoos.
A Majin from the Roman pantheon.
- An Ice Person: She can use a planetary-scale artificial ice age spell based on the divine punishment brought by her mother into the world after Proserpina was abducted. The spell covers the sun and fills the entire world with -60 degree snow and ice.
- Widow's Weeds: Wears Western black mourning clothes and hides her face behind a veil.
TezcatlipocaA Majin from the Aztec pantheon. Rather than the original Tezcatlipoca of myth, this Tezcatlipoca was created in the 16th century, in order to fight against the Spanish who was mistaken for the original Quetzalcoatl.
Forgotten GodA Majin with unknown origins. Lovecraft used it as a reference material, but the fiction and non-fiction got mixed up together so badly that the Forgotten God lost its original form. Research into it was also stopped after people decided there was a connection to Crowley.
- Physical God: As a Majin.
- You Cannot Grasp the True Form: Normal humans cannot properly comprehend the appearance of the Forgotten God. The only impression Kakeru got from trying to look at it is that it was extremely simplified yet incredibly eerie like a stick figure drawn by a small child awkwardly holding a black crayon. The same thing happens with its attacks.
