Marian Slingeneyer

Marian Slingeneyer (マリアン＝スリンゲナイヤー) is a character introduced in Shinyaku Toaru Majutsu no Index. She is a Dvergr, also known as a dwarf. Marian is the first true member of GREMLIN introduced in the series and is essential to their plans as she possess the skills to recreate legendary weapons of Norse mythology.

Appearance
Marian appears a seemingly swarthy skinned young girl. She wears overalls on her bare skin and seem not to wear any undergarments, here she holds several of her tools. Her silver hair is braided, her ears pierced with large circular earrings and she also wears glasses. She wears gloves, apparently for some sort of protection, being that she is magical smithee of some sort.

On her overalls lie the crest of, the World Serpent.

Personality
Unlike other magicians, she seems interested in modern marvels such as a cellphone, and readily wanted to use it along with her weapons. She is also apparently uncaring with the fact that she wears no undergarment for her considerably apparent bosom, or the fact that she is willing to become naked if the situation calls for it.

Despite her appearance, she shows a sadistic demeanor, telling Cendrillon that she will either turn her into a wardrobe or table, as well killing enemies with her transmutation magic in a most ridiculously brutal manner, and using the living bodies as materials or furniture. However, she often shows her soft side, not attacking those who are uninvolved, such as what she displayed to Kihara Byouri before Byouri revealed her true nature. Chatting and caring for comrades, most particularly, Bersi or Kihara Kagun, which was her student, and is close with him, to the point of her breaking down and disobeying orders after his death and is concerned with Othinus after seeing her hurt and bleeding due to her magic tilting to the negative side effect thus making her more eager to complete the lance so as for Othinus to not suffer like that anymore.

She often refers to herself as this Dverger in her introduction, to the point of making it sound like a verbal tic, though it disappears completely in her next appearance. Marian cannot handle beer or alcohol in general, as it makes her sick.

Background
Three years prior to World War III, Marian Slingeneyer met Kihara Kagun after his departure from Academy City. At this time, Marian was not creating weapons of the gods, and was simply trying to improve the tools of the Dvergr, which she hopes to use to let her know about the power and techniques that were on the verge of extinction. Because of this, Marian was looking for skilled individuals and chose Kagun after meeting him. Marian became Kagun's mentor, though directly taught him little, as she thought it would be best for him to learn on his own. At this point in time, Marian had already made Mjölnir, which she uses to air her grievances about Kagun.

Throughout his training, Marian was aware of his reckless desire for revenge, and drew him intentionally into GREMLIN to preoccupy his mind away from those thoughts. The both of them later joined GREMLIN, where Kagun's knowledge in science was greatly appreciated. Despite Marian's plans to change Kagun, he was still fervent on his desire, because of that, Marian began to support to make Kagun strong, strengthening him, as so he can return to her after he carried out his revenge. Despite this, Marian could not ever overturn Kagun's ideal of vengeance.

It is stated that Kagun has been closer to Marian than just as a mere magician of GREMLIN.

Hawaii Invasion Arc
She first appears after the failed invasion of Hawaii, trying out a new cellphone from a hapless vendor, and later somehow connects it with her spiritual item, which promptly blows away the vendor's stand. It was then discovered that she summoned Mjölnir, and rode upon it. Here, she contacts Othinus regarding their successful plan on making Kilauea erupt and the relation of Brunhild Eiktobel with the Gungnir.

Cendrillon, who somehow escaped detention, overhears their conversation, and promptly tries to attack Marian for using her and lying to her of the true plans of GREMLIN. However, she is unable to stop the attacks of Mjölnir and is beaten. Here, Marian threatens her that she will turn her into either a wardrobe or table.

Baggage City Arc
Marian and Bersi, as well as the other core members of GREMLIN willingly agrees to Othinus' plan into turning Baggage City for her experiment on holistic espers requiring the city to be distorted through the battles that would occur therein, though they did not truly know of its true extent as the results would be unsatisfactory for Othinus. Even though Marian was not a pure combat-type magician, she and the others accepts Othinus' plan despite the fact that they are trapped inside the city up until the experiment ends or someone interrupts it. Marian puts up a room of her own near the underground passageways, to prepare for the distortion ahead, here she keeps her weapons, as well as her various furniture, such as Cendrillon, who was turned into a table. She first appears near the beginning of the experiment, where Baggage City is invaded by the Kiharas and Academy City military. In the garbage disposal facility, as she was tasked to defend among other heating facilities for the city. She first slaughters several Academy City military in incredibly gruesome ways using her gold tools. She later meets up with a woman in wheelchair, apparently lost. Marian tries to help her, though figures out her true identity soon afterwards, and attacks her. Marian is later surprised by Byouri's ability to maneuver herself in a wheelchair. Byouri engages Marian with her mechanically enhanced wheelchair, which forces Marian to transfigure the bodies of the Academy City personnel she killed earlier into her form to dodge Byouri's assault. As the battle continues, Byouri reveals that her wheelchair can have legs, making herself more maneuverable. However, Marian later dominates her by bending the legs of her wheelchair, and later cornering her in the burnable garbage area, near a pit for garbage to incinerated later. With her wheelchair stuck, Byouri is forced to use the machine on her legs that allow her to stand up. Byouri takes a machete-like blade from the back of her wheelchair and tries to attack Marian. However, due to her quick thinking of calling Academy City reinforcements for Byouri, allowed her to use their living bodies for transfiguration, and from there catapults Byouri into the pit, leaving her for dead.

Marian returns to her room afterwards, though its magic barrier had stopped working due to the invasion. Here, she carefully pulls out a spiritual item from a box, preparing to counterattack the invasion forces. Marian later goes outside, and makes use of the spiritual item known as Loki's Net. She attacks a contingent of HsB-07s and FIVE_Over Modelcase_"RAILGUN"s, and one particular pilot that tried to challenge Marian was obliterated, and of the debris of his aircraft was turned into a souvenir. With that, Marian orders Loki's Net to eliminate the other aircraft as she goes back down. Returning to her room, she later contacts Sigyn, who is apparently lost, and asks her to give her a suggestion (her magic) to find her. Afterwards, they discuss the true purpose of the Anti-Academy City Science Guardian's Natural Selector tournament, as well as Sigyn's distaste for Marian's choice of furniture. Their conversation is cut short by the arrival of Kumokawa Maria and Oumi Shuri Maria and Shuri makes a run for it, and though Marian pursues them, it is not until she makes use of her "materials", that is humans transformed into the parts of the passageway that they are forced to confront her. As Marian aims at Shuri, Maria kicks at Shuri in order for her to avoid her gold weapons, and warns Shuri not to fight. Maria tries to figure out Marian's powers through a scientific analysis. However, ever haughty, Marian explains that the moment that her gold touches them the alteration of their body begins. Maria employs a passive strategy to counteract this, building damage on Marian slowly, and then the both of them charge towards each other. Despite the danger, Maria's techniques manage to keep Marian's weapons at bay, and she manages to trick Marian, allowing her to wrap her legs around Marian's right leg. With that lock on, Maria was able to exert pressuer on Marian's leg, hurting her. Marian attacks Maria, but the latter gets away before she can hit her. Maria then takes a stance and warns Marian that she can use 8 parts of her body to beat her. However, as soon as Maria charges, Marian uses her remaining human materials, there the floor, walls, and ceiling begin to exude fat, slowing down her advance, and with the water pressure sends forth nuts and bolts towards her. In a moment of preoccupation, Marian attacks, though Maria tries to headbutt her, though Maria is quickly struck down by a rogue bolt knocking her out.

Injured, Marian tries to contact Sigyn for her magic ability. However, she notices Shuri muttering something, and later mimics perfectly Sigyn's voice. Here, it is revealed that Sigyn was already in the grasps of the Kouga Ninja, and had divulged the weakness of Marian's abilities. Shuri shows off that her materials, since they are still human are still affected by alcohol, making them drunk, and difficult to control and alter. Shuri then insults Marian's powers, saying that it is not useful for the Kouga. With a serious disadvantage, Marian flees, with Shuri in hot pursuit. Marian is later seen having escaped Shuri, trying to lick her wounds, though she is later visited by Bersi. Although it is unknown how, the both of them later part ways as Bersi, also known as Kihara Kagun, went out to revenge Kihara Byouri.



Marian later witnesses Kihara Kagun's death after his battle with Byouri, and hither, she breaks down completely. Distraught beyond any rational measure, Marian takes out Dáinsleif, despite Othinus' pleadings, even lashing out on her. Through its use, Marian downs Saflee and Shuri with ease. Maria tries to comprehend what had just occurred, and concludes that it must be the sword, as well as the effects it has on them, stopping their hearts before something even more terrible happens. Marian is impressed by Maria's analysis, although this will not save Maria. Marian unsheathes the sword, and immediately after, her consciousness begins drifting away from her. Suddenly, a right hand appears from nowhere, somehow allowing Maria to retain her life, and immediately after, she discovers Kamijou Touma appears, finally destroying the distortion that has engulfed Baggage City.

Marian tries to use the swords first effect on Touma, but it had no effect due to his Imagine Breaker. Angry for Touma for denying Bersi's efforts (destroying the distorted world that had filled Baggage City), even then Touma will still fight her. Still with the sword sheathed, Marian tries to cut down Touma, to which he realizes that it cannot be negated by his Imagine Breaker. Immediately later, Touma determines the power of the sheathed sword, which collects vectors in a single point and send them directly out. Marian continues attacking, and sucks Touma in the sphere at the end of the scabbard of the sword, but easily manages to get out, and destroys one of her gold tools. Although this was a set-up that would allow Marian to put Touma in a position in which she could strike her. Thinking quickly however, Touma grabs the fragments of the tools he destroyed to cut his uniform and allow it to be sucked into the sphere of Marian's scabbard. With the sphere collapsing due to the pressure, the sphere explodes, sending Marian back and ensuring Touma's victory.

Still adamant in giving up, Marian threatens in unsheathing completely her sword, but Touma plainly tells her that he knows that she will not unsheathe the sword, for she should have done it in the first place, ending all the battles even before they begin. Furthermore, he states that she did not want to draw it, stating that it might destroy more than what she wants destroyed, as well as the fact that she went berserk after Bersi's death, she still managed not to draw the sword. Marian tries to unsheathe the sword, but could not even do it, when the power of the sword begins to emanate. In her moment of hesitation, Touma steps forward and punches her, defeating her.

For the rest of the remaining battles, Marian is unconscious. She later wakes up being carried by Kihara Kagun who was turned into a Einherjar by Othinus. Though obviously hurt of what had become of Kagun, she doesn't complain at Othinus for it. Here, they talk about how Ollerus has interrupted her plans, and that everything was all going to plan as Imagine Breaker has obviously shattered something as Touma entered the city. Othinus later tells that their next goal is in that lone Windowless Building in Academy City.

Eve of the Festival
In the eve of the festival, Marian appears along with Mjölnir and Thor in Academy City in order to collect Fräulein Kreutune for Othinus. Here, she is completely listless after the Bersi's death, not taking Thor's instructions on pre-emptive attacks seriously. Thor presumes that Marian's desperation will have no bounds if Bersi's lingering scent have not remained after being turned into an Einherjar by Othinus.

After Fräulein escapes the Windowless Building due to Touma and Thor's efforts, Marian still remains in the bench she was resting on, but notices that the Anti-Skill are on high alert. She ponders for a moment and asks Mjölnir what they should do, before ultimately disregarding it as too much of a hassle for her.

Marian finally takes action after receiving a lot of information regarding the disturbance in Academy City being related to Fräulein. She asks Thor to handle as she is unsure if she nor Mjölnir can handle her, much to the latter's chagrin. Thor tells Marian to meet up with him in a plaza in front of the District 7 station in order to have more firepower in capturing Fräulein. As Marian tries to search for Thor, she discovers a poster of a bulletin board declaring her to be a dangerous person involved in Baggage City, and that she should be reported to Anti-Skill. In truth, this was a gambit that Touma formulized, by making GREMLIN think that Academy City and Ollerus are attacking them, and Ollerus think that Academy City and GREMLIN are attacking his group. And to finish charade, Thor transforms into Marian for Touma use his picture to post in a public bulletin board, which Thor will direct Marian to. Marian tells Thor that they will have to move to a different hideout in order to take the time to analyze the situation, and she is forced to search for an abandoned building as her posters are up everywhere in the hotels.

Touma follows Marian in order to draw out the scout, and activate the second phase of his trap. He eventually finds Leivinia Birdway following Marian, to which he confront her, making her lose Marian's trail.

During the Festival


Thor and Marian notice the shockwaves of the battle between the reformed Kakine Teitoku and Accelerator. Marian becomes genuinely curious of the events happening, wanting to investigate the goings-on in the city. Marian orders Thor and Mjölnir to make a scene as so she can start gathering people as materials. Seeing as he is the only one who could stop her, Thor first asks Marian who she thinks is causing all the ruckus, to which she replies that she don't know and simply gives out some logical assertions. Thor tries to convince Marian to wait and then attack when they expose themselves, tries to convince her that it may not be involved with them, and at last, tries to convince her through telling her that she might reveal her location. But Marian would not yield to Thor's reasonings, telling him to stand down and find a new hideout as he has yet to be known by their enemies compared to her. Thor gives up in convincing her, and just kicks her, making her unconscious. After felling Marian, Mjölnir is angered and prepares to attack Thor. Thor however states that Mjölnir attacking would put Marian in danger, one of the key components in Othinus' plans, which would fall into ruin upon her death. This is a fact that Thor specifically mentions to Thor would be beneficial for Ollerus, who would then find no need to kill Fräulein Kreutune, and convinces her not to let Marian out. With that Mjölnir's wrath is stayed. Thor says that he will look into how much information Ollerus' group has and what kind of traps they have in store, and states that Mjölnir should prepare so that Marian can escape. As a final measure, Thor tells Mjölnir that if there is something dangerous, she can throw Ollerus' group off by roasting an entire city block. With that, Thor leaves Mjölnir. For most of the arc, Marian is hidden away along with Mjölnir away from the various battles occurring in the city. After the failure of retrieving Fräulein Kreutune, she, Mjölnir, and Thor (secretly Ollerus in disguised), make their way into Tokyo Bay to sneak into one of the many rental ships. Here, she apparently bears no anger against Thor for kicking her earlier. Marian comments on what they will do now with the goals, seeing as Fräulein is beyond them now. Ollerus skillfully relates to her there plan on capturing Fräulein, and references on how there were unforseen elements that he couldn't overcome, and surely something Marian and Mjölnir would not likely overcome. Marian comments on how he should have since he has "Almighty" in his title as Thor, but Ollerus states that it only defined by humans and that he is not a magic god. Ollerus then showed a cooler, and Marian asks what it is, to which Ollerus says will better Othinus' mood after their failure. Then Othinus comes and asks where Fräulein is, of course Ollerus tells her that they have failed. Othinus reiterates that she told them to get her, but Ollerus just tosses the cooler he had. He tells her that it is the original organs of Kakine Teitoku, a suitable substitute to the Fräulein, who is now useless to them. While Othinus remained silent, Marian asks if it would work, since they needed something that was not dyed in magic or science, to which Thor says that Teitoku is a symbol of creation and could create a doll for Othinus to use. Othinus reiterates her point, but Ollerus just tells her that if she wants to get her, she can do it herself, but tells her Fräulein is useless to them now. Othinus calls out to Maria before cutting Ollerus' arm out as punishment, telling her to reconnect it afterwards. However, Marian notices that Othinus' own arm is falling off after picking up the cooler, her fate as a magic god. Having the final piece, Othinus tells Marian that they should begin making Gungnir. After Othinus leaves, Marian tries to approach Ollerus, but is shooed away by him, saying that he can do it himself, and that he doesn't want anyone to look at him in his state. He complains about Othinus' policies, but Marian says that he did well. Ollerus says that he didn't grant her wish, but then says that maybe he wants to cry not because of the pain or in a pathetic situation, but it's because Othinus spared his life. Marian says that he shouldn't worry as she too would have been scared if she was in the same position. With that, Marian snaps her fingers and Mjölnir follows her towards the rental ship. It is unknown if she noticed that the Thor she spoke to was Ollerus.

Lance of Gungnir Arc
Marian and the other core members of GREMLIN were in their base at Sargasso making the preparations to forge Gungnir. Othinus then asks each of the members regarding the status of their assigned tasks to which Marian replied that they have gathered everything they need. She and Mjölnir then went with Othinus to the other side of the ship to start forging the lance

She was then called by Thor (Ollerus in disguise) and since he can't use Mjölnir since she was assigned to support Marian, he'll head off as Almighty Thor. Thor (Ollerus in disguise) then explained that by heading off as Almighty Thor, he might hinder the production of the lance and asked the direction where they are going to draw power in to put together their temple so as not to overlap with their magical symbols, to which Marian handed her memo pad for him to check out. He then told Marian to keep Mokkerkalfe in mind since it may affect the ley lines to which Marian responded that she already knows that and she is more interested in its beating heart.

GREMLIN invasion of Tokyo
While battles are going on, Othinus, Marian and Mjölnir stood at the side of a large pool filled with a thick transparent liquid which is actually pure gold that lost its chemical properties and meaning. Othinus then wondered that the sight before her is what its like when beginning the production of the lance. Marian then explains it to her and assured Othinus that all they have to do is to wait once the process starts, to which Othinus that she won't let her guard down until it passes a certain stage. Marian then responded that she is surprised to find out that a magic god like her can still be nervous.

As the white girl (made of Dark Matter) stood in the center, eight giant flower petals bloomed while fused to her ankles. A great number of electrodes were sticking into the petals and various signals were being sent into the girl via cables. Those signals were producing extended high-pitched screams. The handle of the lance the size of human arm is already visible at the bottom of the pool. Marian then remarked that the process is going well and if the process keeps up, they will surely make it through without issue to which Othinus replied that saying the word 'surely' meaningless. While the process is approaching the manual part, the white girl started to collapse and Marian was in already in a state of panic. Othinus then forced her hand inside the white girl and grabbed the area corresponding to a human’s lungs. She squeezed like a pump to force air out. She then told Marian that the time spent in negotiating will just lead the production of the lance to failure so she instructed her to immediately do the manual switching to continue, to which Marian complied and it was a success. Dark red blood then trickled from Othinus’s eyepatch and the core of Othinus shook. Marian then began to worry for her and said that she could use the help of the other GREMLIN members to mend herself since her magic might again tilt to the negative side. Othinus then told Marian that she will go somewhere and focus on mending herself. Marian then said that just a bit more and Othinus won't have to go through that effort anymore.

When Ollerus finally revealed himself, a great roar exploded out which came from Mjölnir who is connected to Thor. At that time, Mjölnir is assisting Marian in completing the lance. It is unknown if Marian got killed or not, though even Ollerus doubts it himself.

Shifting and Fluctuating World
In the final recreation of the world by Othinus created specifically to break Touma's spirit, known as the Version_Omega world in-text, where several characters from the original world have been "saved" or have not experienced great tragedy, people from the magic side like nuns are allowed to enter Academy City, and seemingly have no complex against science. Notable here is that Mjölnir still retains being a cylinder block. Thor, Marian, and Mjölnir are first seen by Touma right after believing that looking at all the people that he is familiar with in the "perfect world" would get rid of his regrets as he tries to decide on how he should have himself killed. Marian is apparently in a rush for the festival that is happening, to which Thor says that the festival had just started, as such there will be tons of people. He then suggests that being late would be perfect. Marian does not reply but says that she has spotted Bersi and that he is secretly with the ringlet curl maid (Kumokawa Maria), apparently mad. Thor is awed by this, then says that it is Bersi's decision, but says that she should pay attention to Mjölnir as she is shaking in jealousy.

Human Modification
Marian Slingeneyer is a Dvergr, and within her realm is the human body. Marian is shown to be able to modify a "living" human being, willing or not, into any shape she wills with her golden tools, and can keep them in that. Regarding the materials being used, she can use the parts of a human being that is dead for a few seconds before the tissues themselves become dead. Because they are still human, the modified humans are still susceptible to alcohol and its effects.

She also has the power to summon them, apparently, so long as there is gold as a conduit, like the gold parts of a cellphone. Othinus also has enough confidence in Marian to order her to reconnect the arm that she severed from "Thor's" body, despite not being skilled in that area.

Invisibility
According to Thor, Marian can likely use magic of invisibility based on Norse Mythology by wearing various decorations. Also, a common factor for this sort of magic is that the user cannot know for sure whether they have truly become invisible or not. It seems this invisibility can be rendered ineffective by adding some sort of 'seasonings' to the surrounding of the caster, as explained by Thor.

Magic artifacts
Loki's Net (ロキの投網) - A dangerous magical artifact, Marian keeps it inside a box and requires the use of tongs to take out. When Marian wields it, it can apparently take the shape of a flying aircraft, and any object that touches it's wire will be cut. Marian can make of use of it to display written words, as well as have it operate remotely.

Dáinsleif (戦乱の剣 (ダインスレーヴ)) - An extremely dangerous and powerful sword. Marian is forbidden from unsheathing it by Othinus, and she all together does not want to use the power if the sword is completely unsheathed. Unsheathing a little bit of the sword, can cause an ineffably great fear upon its target, forcing the body to stop its own heart at the fear of a much terrible event that would occur if the sword is completely unsheathed. Kamijou Touma is immune to its effects and can negate it entirely upon those who have been affected by it. It is later revealed that when fully unsheathed, it is capable of cutting away Phases and the protection of the Gods associated with them, drawing out massive amounts of power and manifesting them in the form of the calamities sealed away by those Gods, allowing the user to effectively wield the "endings" of the world seen in various mythologies and religions.

Draupnir (万象の金(ドラウプニル)): After Othinus abandoned GREMLIN, Marian created Draupnir from the components of the abandoned lance. Based on the golden, dwarven-forged ring worn by Odin, it consists of two gold bracelets with the design of a serpent eating its own tail. It allows Marian to freely bring together any magic sword or divine spear on a level that humans can use. When used, the bracelets expand to 30m across, remaining in place around the wrists, before disappearing in a flash of light, forming the desired weapon.

Hrímfaxi (月輪神馬(フリムファクシ)): A transportation spell or spiritual item, named after the horse of Nótt, the personification of night. Marian used it to get from the Sargasso in Tokyo Bay to Denmark, apparently making quite a show in the process.

Design evolution
She was designed originally for the 3rd New Testament volume, but Haimura decided not to release it to avoid spoilers. Her design is later revealed in the 4th New Testament volume, and based it around that Marian is cruel person with a cute face. She was designed to look like a blacksmith because her tools would make her look similar to that of Sasha Kreutzev.
