Othinus

Othinus (オティヌス(オーディン)) is a character introduced in Shinyaku Toaru Majutsu no Index.

She is a Magic God, and is the leader of GREMLIN. A powerful being who refers to herself as a god, she is the primary antagonist for much of Shinyaku Toaru Majutsu no Index.

Etymology
Her name,, is the Latin name for the  of war, wisdom, magic, poetry, and betrayal among other things, which is also the alternative reading of her name. Her name is derived from the , a euhemerized account of gods and their relation to the history of the Danes, which tells of Othinus' throne being taken by Ollerus after the former's exile.

With this, the characters of Othinus and Ollerus in the series are an exaggerated reflection of their roles from the Gesta Danorum.

Appearance
She is referred to as One-Eyed Othinus and, similarly to the Othinus of legend, she wears an eyepatch over her right eye which she has presumably lost in order for her to drink from the, though this may just be a ritualistic and aesthetic choice, as Othinus is maybe invoking Idol Theory to match that of Odin of Norse mythology. Her remaining eye is glittery green and with slit-like iris, though not often the case in illustrations.

She is described as having the external appearance of around a 14 year old girl. She has long, wavy hair of blond. She's seen dressed in a revealing outfit, a low-cut neck line that goes down below her navel. She has a long cape, and has ribbon wrapped around her. Traces of a witch-like design is present, such as the cape and a wide brimmed hat with a pointed tip.

Personality
Othinus is a ruthless and cold-hearted individual who will utilize any means necessary to achieve her goals, regardless of how much destruction and suffering they bring to others. She has no qualms about threatening or harming anyone who inconveniences her in the slightest way, be it an enemy or an ally.

She is very conniving and manipulative, able to fool everyone that knew her that there was only one method in creating Gungnir. As her namesake Odin is also a god of betrayal, it is only fitting that she has no qualms in using and then casting aside her comrades to get what she wants. In the same breath, she was very easily angered when Ollerus called her a lonely person and finds it frustrating when people she's trying to defeat continue to inconvenience her.

Upon acquiring the Lance of Gungnir, she declares her victory and immediately destroys the universe on a whim. Due to being able to create and destroy whatever she desires, she now paints the world as she desires it to be, such as erasing all forms of crime or pain from it simply to make it more appealing rather than for the sake of those living in it. She also seems to treat Touma's continued existence like an amusing game until he actually started to become an inconvenience to her.

Ultimately, she is also both afraid of Imagine Breaker and also afraid to get rid of it, as she is aware of the fact that she can transform the universe into any form she chooses but could also easily end up losing her way back to the original version of it. Because of this, she was ultimately unable to kill Kamijou Touma and resolved to break his will instead.

Othinus ultimately desired to return to her original world, which she previously eliminated with her powers as a magic god, ultimately leaving her with the stated trauma of losing Imagine Breaker, which could be used as a reference point for that world. After ultimately defeating Touma, Othinus comes to terms with this, realizing that she wanted him to understand her and put him in the same situation she was trapped in to that end. She decides to restore Touma's reality with Imagine Breaker's reference, and resolves to die as an enemy of the world.

As a legendary figure and creator of worlds
An unknown number of years and Phases ago, Othinus, though she may have had a different name back then, became a Magic God, and many tales from many cultures told about her power, though some would make her seem like an old man or a vicious god of war, there were implications that she herself would deliberately take forms that would now be recorded in mythology. Othinus later used her power to change the world, starting a new Phase. However, she later yearned for her original world, and despite the fact that she could have used the Imagine Breaker to change the world back, her hesitations prevented her from doing so. For there was hope that she could make the world into her original world as she saw in her mind. Moreover, there was a hope for her that she could just bring the world into a new Phase and just settle there. Regardless, she suffered for it, and for countless Phases she was worn down by the suffering that she felt in each of them, something she would later visit upon Touma. Due to being worn down and the impermanence of the world, she began looking for something that would not change. Specifically, she was looking for someone who can understand her, the only one seemingly constant in the world. Though she didn't know what she wanted herself—that changing the world was but a means to an end. In the end, she settled in the current world, and somehow relinquished her title as Magic God.

Return as a Magic God
Her unease later returned, however, taking back her title as a Magic God, earning the anger of Ollerus, forming an adversarial relationship with the man. In fact, Ollerus would continuously claim that Othinus stole becoming a Magic God from him. This relationship between them extends with his magic. The first implication of Othinus' existence in the series is when Ollerus uses the queer magic, Hliðskjálf, upon Sogiita Gunha. This magic, of course, is named after the high seat of Odin, which allows him to see into all realms. In the , Odin was exiled and Ollerus was chosen to take his place. This can be presumed why Ollerus currently has the Hliðskjálf.

During Thor and Touma's battle at the end of the Ichihanaran Festival Arc, Thor mentions Othinus taking extreme measures to gain knowledge such as pulling out one of her eyes, and hanging herself on a tree. This likely refers to Othinus steps in becoming a Magic God again after relinquishing it before her unease in the current world returned. This method is a reference to the Odin of Norse mythology, who sacrificed his eye at 's Well of Wisdom in order to gain the Wisdom of Ages, as well as hanged himself on the world tree for nine days and nights, in order to learn the wisdom that would give him power in the nine worlds.

World War III would later spurn her into action even further, as she forms GREMLIN for the purpose of constructing the Lance of Gungnir.

As Othinus is a Magic God in spite of her limitations, she is one of the most powerful beings in the Toaru Majutsu no Index storyline, and as demonstrated later, is able to reshape the world according to her will using the Lance of Gungnir.

World War III
Othinus is mentioned in passing by Ollerus after finding Fiamma of the Right, referring to her as the person who stole his title of Majin.

Othinus was aware of the events of the war, along with other members, though it is unknown when exactly she formed the group that would be known as GREMLIN. The members were either watching or taking part in the battle to see if Academy City would survive it. However, they did not want to have anything to to do with World War III. Moreover, they did not have anything to gain from helping Fiamma of the Right, as even if he succeeded, his method would not have saved the world as he thought it would. Since the opposite occurred, they did not want Fiamma of the Right, Roman Catholic Church and their Christian Alliance with the Russian Orthodox Church's losses to be forced upon them, and declared their own War with Academy City.

Shinyaku Toaru Majutsu no Index
All from the beginning, Othinus planned to acquire Gungnir, the key to changing the world into her favor. Fitting her namesake of Odin, she played her comrades for fools. She used them to help her aid in the creation of Gungir, in spite of being able to create it on her own, propagating false information that there was only one method and that it was the only way to acquire Gungnir. But it was just one of the many branches she can get Gungnir, and though it would've worked as well, she could easily make it own her own. This is because she used it as a decoy for her subordinates and especially those of her enemies who will surely interfere.

But her problem with the infinite possibilities of being a magic god still troubled her. Intending to unify her infinite possibilities, she saw that she could only rely on achieving 100% success through the fulfilling the decoy plan, seeing as the Imagine Breaker, being the reference point of the world is of no use. And she saw no way to achieve 100% failure as well, as she has reacheve a level where it would be difficult to obtain a truly 100% and thorough defeat. Thus begins the violent struggle to create Gungnir.

Hawaii Invasion Arc
She appears in voice-only, talking to Marian Slingeneyer the Dvergr, over the phone, regarding their plans, and their successful fulfilment of one its steps, the eruption of Kilaeua and the spreading of volcanic ash upon the world, and states on how she has gotten a report regarding Brunhild Eiktobel the Valkyrie, who once used Gungnir, a portion of it however. Their conversation is interrupted by the arrival of Cendrillon, who is quickly defeated.

Baggage City Arc
With Bersi's knowledge in the darkness of Academy City, she allows him to be the only to know the true extent of the distortion that would occur for the experiment in Baggage City and orders him to adjust the experiment depending on the scope of what Academy City's forces that would inevitably attack.

After Bersi's death, Marian Slingeneyer swears to avenge him and prepares to unsheath Dáinsleif, the harbinger of. Othinus calls the Dvergr and beseeches her not to do it, or she would ruin GREMLIN's experiments. Marian merely scoffs at her.

When Kamijou Touma defeats Marian Slingeneyer and prepares to destroy Dáinsleif for fear it could be mastered and used at its full potential, Othinus reveals herself, stopping Touma and severing his right hand crushing the wrist.

Othinus promptly destroys Dáinsleif with her powers, cursing how Marian had to create such a thing. But then, the Invisible Thing within Touma tried to break free, though Othinus used her powers to suppress it, seemingly unimpressed with its state and form. It is then that Ollerus appears to confront Othinus, suggesting she leaves with Marian as he has business with the Imagine Breaker. The two spar and browbeat each other until Ollerus reveals he has Fiamma of the Right on his side, empowered by the fact that Kamijou Touma's hand was severed, allowing his world-saving powers to activate. Seeing this, Othinus begins to carry off Marian, but decides on a whim to fight and kill them off. The match ended in a draw.

Later, Othinus used her powers to raise the deceased Bersi from the dead to join the Einherjar and carry Marian for her. There, she declares the pieces are coming together. Having acquired a proper furnace in Hawaii and Gungir's blueprints having been stolen, all that's' needed is a specimen to become a Holistic esper — someone greater than a human, without Valkyrie or Saint properties that hasn't been altered by Academy City's Power Curriculum Program. Such a specimen exists within the confines of the Windowless Building.

Ichihanaran Festival Arc


Othinus appears at the end of the arc to meet the members of GREMLIN in a port in Tokyo Bay. There, she questions and then punishes Thor (who is actually Ollerus in disguise) concerning his failure to capture Fräulein Kreutune, by cutting off his right arm. However, the magic she used ended up being in the negative 50% of the infinite possibilities, so as a result her own right arm started to fall. She then decides to pick up the organs of the original Kakine Teitoku and use this new option to begin manufacturing the spear, unaware in that her group has been infiltrated.

GREMLIN invasion of Tokyo
She has GREMLIN parked Sargasso on the waters near Tokyo instead of directly attacking Academy City. This is so that they can distribute what people hoped to gain, put pressure on Japan, Academy City, and all the nations who are against her, as well as the people living in Tokyo in order for them not to rise up in a unified force to attack her, which was the same way how Fiamma of the Right was defeated during World War III. There, Othinus and the other core members of GREMLIN are in their base at Sargasso making preparations to forge Gungnir. She then asks each of the members regarding the status of their assigned tasks and assigns Thor (Ollerus in disguise) to intercept the attackers once the lance enters production stage. Here, she is completely oblivious that both Ollerus and Fiamma of the Right is hiding within Sargasso, waiting for the moment to strike her down.

Once the parallel processor was finished by Bersi, he set it up to send signals to Kakine Teitoku's flesh and blood organs in order for it to produce Dark Matter. After some time, the organs produced white sticky substance and gathered to form Teitoku's own body. Othinus and Bersi both realized that Teitoku is already conscious. After hearing the conversation of Othinus and Bersi regarding of using him for their own purpose, he started to devour all the equipments attached to him and declared that all he knows is their fate for using him as a tool then attempt to attack them. He formed a dome around the headquarters of GREMLIN and proceeded to attack. Before the attack arrived, Othinus subdued Teitoku by unhesitatingly grabbing Teitoku's neck in one hand, digging her fingertips to his neck. At that instant the dome collapsed. Othinus and Bersi then exchanged a few short words. Othinus then forced Teitoku to submission and transformed him into a mass the size of a volleyball then tossed it to Bersi and commanded him to do what needs to be done with it. She then senses that their base was already found by their enemies. Once Bersi's assigned task was complete, Othinus then instructed him to intercept their enemies and destroy what needed to be destroyed to buy them time while producing the lance.

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. She then mentions that what they are doing is essentially a magic ceremony but cannot be completed solely with magic since the automatic work will stall somewhere. To accurately throw in the holistic esper and continue the ceremony with the proper timing, it needs to be switched over manually.

As the white girl, the Holistic esper (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. Othinus then told Marian that she will go somewhere and focus on mending herself.

Othinus suddenly appeared behind Thor (Ollerus in disguise) after he destroyed Mökkurkalfe and asked what is he doing. Thor (Ollerus in disguise) then said that it is about time and threatened Othinus regarding Marian. Othinus then threatened him to show his true self and he transformed back to his true self. She then questioned Ollerus motives of being there and someone's life or death won't stop her from carrying out her plan. Ollerus then remarked that he is glad that she didn't see through his plan and her infinite possibilities send her power to the negative direction. Othinus then responded in disappointment that there is no way she would add him to her ranks of Einherjar and she would totally obliterate him and Ollerus responded to her mockingly to which Othinus responded by creating tens of thousands or even hundreds of millions of strange explosions in the slight space between them. The battle between Ollerus and Othinus goes on then immediately, Ollerus rushed up to Othinus while disregarding the damage he is taking. He then jabbed his glowing palm at the center of Othinus chest to turn her into a fairy based on the idea that fairies were former pagan gods that were shrank down by Christianity without being aware of it. In that way, the magic god will be returned/dragged down to the territory of a human. But despite that, Othinus just laughed and told him that she deceived his senses and thanked him for giving her a means to finally defeat him. She then used the same move against Ollerus to turn him into a fairy. Ollerus then staggered and said that his second hope is still on track. Othinus was confused then suddenly she was stabbed by the same spell again, this time by Fiamma of the Right who seems to appear out of nowhere. Ollerus then told her that he no longer have an interest in becoming the magic god but he won't allow someone to misuse it. At that moment, it seems that it is all over for Othinus but she just laughed. She then told them that she doesn't care whether she lose, what's important to her is unifying her infinite possibilities. She only needed it to lean in one direction or the other. It did not matter whether she completed the lance and have 100% success or become a fairy and have 100% failure. Whether she win or lose, she will be a complete magic god. While saying all these things to Ollerus and Fiamma, Kamijou and the others approached GREMLIN's base. As they approached the end of Sargasso, Kamijou doubted if it is still part of the real world. He then sees Ollerus' body fall from the deck of a passenger ship. Othinus then told him that he was too late. Kamijou then asked about the lance to which Othinus responded that it all ended in failure but it didn't matter to her since all she wants is to complete her position as the magic god and as long as there is a way of doing it even without the lance, it doesn't matter anymore. She then told Kamijou that all of it was just a decoy, even the formation of GREMLIN and everything that happened in the past. Othinus then pulled the lance of gungnir that she made herself from her right eye socket. While Othinus laughed, Kamijou was speechless. She then declared that she is now a complete magic god by having both solutions at once to which Kamijou just screamed. Othinus then lightly spun the lance around in one hand and pointed its tip toward the heavens and said that little fights are so troublesome, thus she'll just end the world. And exactly as she had announced, everything was immediately destroyed.

Shifting and Fluctuating World
The world has truly ended, and while in the Black World, Othinus told Touma who just woke up that he failed to save the world and told him that she isn't interested on what he will be going to do. Touma stood up speechless, noticed his surroundings and asked Othinus about the place they were in. As Touma continues to deny what he is seeing and not accepting the fact that the world had really ended, Othinus told him that what she destroyed is not just the Tokyo Bay or the Earth but the whole universe itself and only the two of them are left. Touma could not still believe it and walked away from Othinus as he wandered around place. After walking for a very long time, Touma accepts reality and wanted some kind of a landmark. He then realizes that Othinus is still there and decided to go back to face her. When he came back, Othinus told him that she thought that he had already died somewhere. Touma told her that there is nothing there and that he will find a way to meet again the people who have disappeared. Othinus told him that there is nothing he can do now that the world has already ended. Touma then told her regarding his Imagine Breaker as a reference point as what Ollerus said and will find a way to revert everything she threw out of order. Othinus then told her she is fine with it and that she already expected Touma as the final barrier. Despite the fact that she could kill him easily at that moment, she didn't because she thought that if she killed him, Imagine Breaker would just reside somewhere else and it would be problematic so she decided to just break him mentally and use him as a cage to trap Imagine Breaker. Touma then challenged her for a fight but Othinus told him that a magic god like her won't bother fight a puny human. She then pulled her lance from the ground and it glowed signifying that she is creating something. Touma then wondered what she is doing and she told him that she is going to break him mentally by taking everything from him and show him the insignificance of everything that he has gained in his life.

In the Alpha World, while Touma is still in the bedroom and is at lost on what is happening after knowing that the world treats him as an evil person and wants him dead, Othinus suddenly appeared and told him that the world have realized that this great commotion would not end unless they kill Touma. Touma while trembling asked her what have she done to them, to which Othinus responded that she did not threaten them and that this is the current world and not just a nightmare. She then told him that he would eventually die and nothing will change that. Touma then looked around the destroyed bedroom but Othinus had already disappeared. After Touma escaped the police officers who are pursuing him, Othinus appeared again to Touma on top of a telephone pole and told him that he overcame his first trial. Touma then questioned her what did she do to which she responded that she just merely changed everyone's point of view then vanished yet again. Touma then learned that after the war, Japan was set up such that it would dry up on its own without help and that the pile of rubble that he was in is actually Shibuya. He then thought if the GREMLIN or coalition did this, then Othinus suddenly responded that it wasn't her and it doesn't seem to be over yet then vanished. Touma then heard an announcement coming from the store's speakers that the students who had fled Academy City were the target of bombings. The attack landed and the shockwave affected Touma. He began to ran toward the station hoping that the people hiding there were not wiped out, then suddenly Othinus appeared alongside him riding an electric two-wheeled vehicle that she had picked somewhere while telling him that he shouldn't be so sure about that and things might not go as nicely as he thinks he will. Touma tried to punch her but she disappeared along with the vehicle. Touma then reached the station and saw Fukiyose Seiri. While he is attempting to save her, she suddenly stabbed him and blamed him for everything that has happened. An LCD TV burried in the rubble came to life and showed an announcement that a second and third wave of missiles are coming right at that moment and the missiles came. The ground of Shibuya Station collapsed and Touma fell. Othinus showed herself again to Touma while falling through the deep underground of Shibuya Station and asked him if he understood now that this is a world with a different point of view. Touma then asked him what point of view did she changed to make this world to which Othinus answered that she changed everyone's point of view concerning him. Touma then awoke from the impact of falling and heard an announcement that Academy City has had all supply lines cut off. He understood that most people in the world hated him and that any people or organizations that were connected to him were being indiscriminately targeted. Othinus yet appeared again leaning against Touma's back while he is confronting Aogami Pierce who is about to attack him. She told him that she did not brainwash them nor added anything new but just changed their point of view. She also told him that he had already done what it would take to be treated like this and it's just that he and the others haven't realized it before. Continuing on, she told him that in the world he knows, he always charged headfirst into some kind of incident using his fists to defeat the enemy and protect someone as a result then being treated as a type of hero and only that positive aspect was emphasized. She then continued on by whispering to him about what will happen if their point of view was changed and emphasized the other side of his actions, specifically the negative ones and that it would be strange for people to silently accept an incarnation of violence like that. After saying those words, Othinus cleanly vanished. Touma then fought Aogami who is blaming him of everything and defeated him. He ran away while thinking about the safety of his parents. Othinus appeared hung upside-down the ceiling; apparently knows what he is thinking, she then told him that she wouldn't stop him if he wanted to see it for himself and that he should be more cautious of his surroundings. Suddenly, he was stabbed by Komoe from behind. Komoe then apologized and told him that she have to take responsibility. The LCD monitors in the station suddenly lit up and showed his father announcing that despite the fact that Touma is their son they are willing to help everyone in order to kill him because he is an absolute evil and that they will correct the mistake they made. Othinus then appeared staring down at him while crouching and asked him who in the world actually saw him for who he was. She then tried to break him by telling him that people were not actually looking at him and that they do not see him for who he is and that is the reason why they were easily manipulated by changing their point of view. She then asked him if this kind of world is worth risking his life to protect, to which Touma responded that it is. She then realized that she could not break him that easily and decided for a slight change of plans. At a snap of her fingers, time sped back to normal and Komoe proceeded to kill Touma.

In the Beta World, Othinus sat on the teacher's desk in the twilt classroom as evening fell while Touma is contemplating on what he just saw earlier in the class. It turns out that there is an impostor who is living his normal everyday life and the others did not notice it despite the striking differences in their appearances. She told him that it was “Kamijou Touma's” everyday life and that for those people, it did not matter who it was. She explained to him that their trust was established because he saved them so as long as they are saved, regardless of who saved them, their trust and good will would have turned in that person's direction. She told him that anyone could be 'Kamijou Touma' and that no one is truly looking at him. She then asked him if he can still continue on to which Touma replied that he won't deny this world he protected and it's valuable for him. Despite Othinus trying to break his will him, Touma still decided that it is alright if everyone abandon him and that he will just rebuild his connections with them. Othinus then asked him who he is, then Touma realizes that he no longer knew who he was. While Touma is contemplating about his identity, Othinus asked his name, what kind of person he is originally, the kind of people he is surrounded with, as well as the person he wanted to protect. She told him that as thanks for letting her kill some time, she will return him to his former position as long as he tells her his proper name. She showed him his own class photo and told him that if he chose correctly who he is in that photo then she will return his world, life and existence. Despite the fact that Othinus is trying to break his sense of identity, he insisted that he is Kamijou Touma. Othinus utterly displeased asked how did he catch on to which Touma replied that she gave him a hint.

Othinus then made Touma experience countless of worlds. Touma then realized that Othinus isn't actually destroying anything. Othinus then explained to Touma about Phases and on how she just creates new filters and place them over the world so the world appears to have changed. She then mentions a man who names himself “Silver Star” seem to have been attempting to directly tamper with the 'Pure World' beyond all the filters. Touma then thought that his Imagine Breaker does the opposite of what Othinus is doing and that his hope to bring everything back to normal was renewed. Othinus knowing what Touma is thinking warned him regarding that last thread of hope. In the Omega World, Just as Touma had his resolve in bringing back everything to normal, Othinus showed Touma a seemingly perfect world where everyone was saved and enjoying their everyday lives. She told Touma that if he insists that the changed worlds and the act of changing the world are evil, then he should reject this perfect world. Othinus embraced Touma's shoulders from behind while holding the lance which is within reach of his right hand. She then told him that it must be right to return it to normal and that he should test out his own idea of justice by rejecting this perfect world. Othinus explained to him that the world does not need him and that even without him, everyone can be saved by using her power as the magic god regardless of the issue of good and evil. Touma then complained that it isn't fair and questions himself about what he is doing all along. He also complained that he could not save everyone and that his actions might have caused tragedy to other people. Othinus told him that he should not blame himself and that he had done well for a mere human. Suddenly, Index approached him for her ball and Touma reached for it. He also saw Stiyl, Kanzaki, and other priests and nuns that he did not recognize. Index then asked him what's wrong to which Touma responded that it's nothing. Index then jogged away and went back to her group. Othinus then let him choose whether to protect or destroy to which Touma asked what else he could do since even if he does not do anything, she can save the world. She then told him that the perfect world was created on the assumption that he does not exist and him existing for much longer in this world will cause it to begin collapsing so he must end his life. Othinus is at the schoolyard of A Certain High School when Touma showed up. It irritated her that Touma is still there and alive when he should have already killed himself after accepting the perfect world that requires that he must not exist. She then decided that she will just kill him if she cannot break him and that she might achieve more stable control if she transfer Imagine Breaker to a more fragile container and break it. And thus the battle between a man and a god began.

Without moving from her position, she sent explosions to Touma by just holding up her lance. Touma attempts to come closer to her but it is futile. When he almost got the chance to punch her, she vanished then appeared so close to him and grabbed his neck. As she lifts him up, she told him to realize it already to which Touma replied that he already have. Touma realized that they've been doing this countless of times already and that she won't kill him for a reason. Othinus then felt exhaustion due to the fact that they've repeated this countless of times until Touma fails somewhere along the line. But Touma wouldn't break and she shouted in irritation. Othinus killed Touma over and over again while Touma speaks to her. Touma then told Othinus that she couldn't throw away her first and ideal hope of returning to her original world by removing all of the phases that she have put in place and that her second hope of creating a world similar to her original world would still be different from the original so she couldn't abandon her first hope. He claimed that she should be able to use Imagine Breaker to repair the world and that he will do whatever it takes for her to bring back his original world. Othinus then responded that she tried it but it didn't work so her only option is to create the next world. Touma then told her that he won't move onto the next world and that they will repeat this billions or even trillions of times. After the 10,031st fight, she already have decided to end this and that she would give up on her first hope but suddenly she felt an intense headache. Touma explained that fighting with a weak opponent would wear down her mind at a faster rate as compared to his case wherein fighting a very strong opponent, would wear his mind at a slower rate. Othinus then decided that she would end this and kill him here and will move on to the next world. Othinus continued to attack Touma but he just evaded it and told her that all this time, he is analyzing her attack patterns and somewhat started to understand her. She then throwed the lance to Touma at a tremendous force that the space itself has torn apart but Touma used his right fist to strike it then the lance veered sharply upward to return to Othinus but it disintegrated midway. Touma then thought that he could end this due to the fact that Gungnir, the item that grants her 100% success has been destroyed but Othinus used the fairy spell to grant her the 100% failure. Othinus then used her crossbow to rain down arrows on Touma. Touma eveded the first nine arrows but he did not anticipate the tenth one due to not considering the 100% failure in his analysis so he was struck and his lower body was blown apart. Othinus caught him in one hand and told him that it is over. Touma accepted it and told Othinus to put Imagine Breaker into good use to take back her first hope. While dying in her arms, Touma told her to just act the way she wants regardless of good and evil and asked her what she really wanted from the beginning. He then died. As she stood alone in the pitch black world, she then realized that she no longer remember why she wanted to go back to her original world and that what she really wanted is someone who understood her. She is not assured that if she go back to her original world, she would be able to find that someone. She realized that Touma was the only one who truly understood her and that she just killed him with her own hands. She then decided to bring back Touma's original world. Touma woke up and saw that they were once again at Sargasso. Upon seeing Othinus, he realized that Othinus has already changed and conceded the world to him. He tried to stop Mikoto, Index, Leivinia and Lessar from attacking her but it didn't reach them. Othinus did not attempt to defend herself and was knocked backwards. Touma then ran to Othinus to his friend's surprise and searched for her. Meanwhile, Othinus is laying on the ground accepting her fate as the magical bombardment from the coalition falls on her. Touma then used his right hand to protect Othinus from the bombardment which surprised Othinus. Touma then told her that she knew that this would happen but still kept quiet about it to which Othinus responded that she would not last longer due to the fairy spell destroying her from the inside and that it is too late even if he use Imagine Breaker. Touma told her that she is different now and that she must atone for what she did and he can no longer sense any evil in her for her to deserve death. Touma then declared that he will save her even if it means he would fight the world.

Abilities
Othinus is a Majin, which makes her a perfect and pure magician that encompasses every possibility. Because of this, since it is every possibility, she has an equal chance at succeeding and failing, making her magic a 50/50 shot. The reason she seeks to craft and wield Gungnir is to control the probabilities of her success and failure, effectively ridding herself of 50/50 restriction, though it is later revealed that she can bypass this by completely failing as a magic god herself. To unify her infinite possibilities, she either needs to become 100% successful at becoming a magic god, hence the reason for the complicated ritual for Gungnir, or 100% failure which she has a hard time of acquiring. After becoming struck by Fiamma of the Right's Turn into a fairy spell, she falls into 100% failure, allowing her to unify the possibilities and becoming a perfect magic god. Despite this, if she is successful in using her powers, she has shown to be extremely powerful. She is able to use pure strength crush Touma's right hand as well as the invisible thing that came forth to attack her with strange ease, rip out Ollerus' (disguised as Thor) arm, dig into the neck of Kakine Teitoku and cow him, and force the Dark Matter-made Holistic esper girl to keep on performing its task. She, as well as Ollerus, is also able to create hundreds of millions of strange explosions. When Othinus and Ollerus fought the explosions were not strong for their own but in such a great number they seemed like twisting the space and time. Both of them have not used a special move, a form of preparation or a magical tool before they started this attack.

Othinus can even deceive others' senses. She used this to make Ollerus believe he stabbed her with his Turn into a fairy spell whereas she was unscathed.

Furthermore, as she is based on the god Odin, she has territory over the dead, which allows her to turn Bersi and other humans into an Einherjar, though the process is unknown. It is likely that she too is the one who created the Artificial Valkyries that attacked Brunhild Eiktobel.

With the Lance of Gungnir
Gungnir (主神の槍 (グングニル) ): The spiritual item desired by the Magic God Othinus in order for her to remake the world. It is the lance of the head Norse god whose handle is made from wood of an ash tree, its sharp tip made of gold and personally carved runes that gives it tremendous power. Apart from the fact that it grants the Magic God 100% success, it is also used as a throwing weapon. It would always hit its target once thrown, could not be shot down or destroyed mid-flight, it would always return to its owner's hands once the target is pierced and it is said that it could destroy the symbols of human power.

Wielding Gungnir gives her the power to destroy the world, but in reality it is revealed that she isn't exactly destroying the world or anything. She creates new Phases and place them over the world so that it would appear as if it had actually changed. Along with the world, she can also alter the point of view and memories of its inhabitants. Also, with the lance, she has a free control over the life and death of humans through a perfected version of her Einherjar spell but it can't apparently affect beings who are both "dead and alive" like the Will of the Whole Misaka Network.

Other abilities

 * Turn into a fairy (妖精化): After seeing Ollerus perform the Turn into a fairy spell, she is easily able to mimic Ollerus' invention and use it effectively against him, bringing a "god" like him into the realm of fairies and being killable. She uses it successfully on Ollerus, destroying the interior of his body. Using the principle of the spell making her into a 100% failure, she is able to still use powerful magic if she does actions that are opposite of her initial impression. Indeed, despite the destruction of Gungnir, she was able to use her tremendous power in order to use the Imagine Breaker as a reference point and return the world back to Touma's original world.
 * The cost of using the spell to make use of the 100% failure however, is that it would wreak havoc on her body, giving her tremendous pain and suffering as well as make her slowly lose her power as a Magic God. Even the Imagine Breaker would not be able to amend its effects.


 * Othinus' Crossbow: A phantom weapon that can simultaneously hold ten arrows in a fan shape. In the legends, it was said to have a frightening destructive power that could exterminate an entire army. When using it, disturbing symbols starts to manifest from Othinus' back as it gathers tremendous power and the black world acts as the crossbow itself. Ten arrows will then rain down on the opponent, though shown to be in different directions, distorting space-time in the process. The spell was only seen after Othinus used the 100% failure aspect of her being a Magic God through the fairy spell. It is unknown if Othinus could use it if she had Gungnir.
 * The spell is likely based on the crossbow of the mysterious old man found in the Gesta Danorum who aided Thuning in his quest against Hadding. Here, the old man uses a crossbow which could accommodate 10 arrows in its string at once against Hadding's men. As Odin often took the form of an old man it is likely the author equated this old man with that of Odin as a basis for Othinus' spell.


 * Bone Boat (骨船(こつせん)): A spiritual item in the form of a bone, resembling an animal's leg, with strange writing carved onto its side, normally kept in Othinus's hat. Like the crossbow, it is an item associated with Othinus rather than Odin. It can freely change size and cross the world's oceans in an instant, however rather than moving its users across the world, it moves the world itself around them and moves it back to its proper position after they disembark.

Character Art Designs
Haimura states that for his first version of Othinus, he had added all sorts of elements based on the keywords "magic god" and "witch". However, he believed that the first try lacked refinement thus continued on with a re-design in the second version. Haimura wanted to give a bit of similarity to Index and Sasha who are in a similar category. But he also handled the lines in the same way as certain other GREMLIN members like Cendrillon and Thor (that is, a composition of flowing lines.)

For Othinus' final design, he touched up the second version. He could not have her butt exposed, so he decided to hide it a bit.

Haimura explains the reasoning for her having so much exposed skin being the idea of "truly strong people do not need excessive equipment." Commenting that Aleister, Aiwass, and Ollerus are similar in that way and the opposite would be Biagio. By exposing her body and casting aside anything to protect her, she is showing that her enemies' attacks and hostility mean nothing to her. Haimura also comments that for those who have read the side-story Kanzaki:SS, might notice something about Gungnir.

 * (To Kumokawa Maria, from NT4) "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."
 * (To Ollerus, from NT6) "Distance holds no meaning. What matters is being unseen."
 * (To Kakine, from NT8) "Listen, you piece of scrap. I only expect one thing from you. Just one. Be of use to me. …If you can’t, I’ll carefully remake everything about you until you can and do. It will be like holding a girl’s head down and beating her face into something completely unrecognizable with your fist."
 * (To Fiamma of the Right and Ollerus, ibid): "After coming this far, do you really think you have any chance of fighting back? The two of you were only able to crawl through the dirt because you could not leave the territory of fragile children of man. Kneel before me as you witness history. This is 100% success!!"
 * (from NT8): "These small fights are such a pain. I think I’ll just end the world."
 * (To Touma, from NT9): “No matter how many people surrounded you, none of them were actually looking at you. After seeing your name, your outer shell, and a list of your actions, they decided for themselves what kind of person you must be. That is why their impression of you was so easily manipulated by changing their point of view.”
 * (To Touma, from NT9): “It didn’t work. I tried it and it didn’t work!! Even with a palette knife to peel away the paint and even when I peeled it away in extremely thin layers, I wasn’t satisfied with the result. There is no longer a convenient path leading back to the way things were. The age can only advance. If what I want is not before my eyes, then my only option is to create the next world!!”
 * (To Ollerus, from NT10): “You weren't the one who understood me. He was a lot stronger than you.”
 * (To Touma, from NT10): "I was already saved the moment you said that to me."
