Othinus

Othinus (オティヌス(オーディン)) is a character introduced in Shinyaku Toaru Majutsu no Index. She is the current Magic God and is a true member of GREMLIN as well as its leader.

Etymology
Her name,, is the Latin name for , the of war, wisdom, magic and poetry, among other things, which is also the alternative reading of her name.

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.

She's seen dressed in a fur coat and a black leather oufit. She also wears a wide brimmed hat with a pointed tip, one which would have been worn by a witch.

Background
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. It is a reference to the Odin of Norse mythology, who sacrificed his eye at {{w|Mímir]]'s Well of Wisdom in order to gain the Wisdom of Ages, as well as hanged himself on the world tree {{w|Yggdrasil}} for nine days and nights, in order to learn the wisdom that would give him power in the nine worlds.

Othinus would later attain the legendary title of Majin from Ollerus, which Ollerus proclaims to have been stolen from him, making her one of the most powerful beings in the Toaru Majutsu no Index storyline. This would mean that the girl that currently holds the title, has named herself as Othinus for a long time before even the creation of GREMLIN.

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.

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 the 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 arm and crushing it.

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 arm 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.

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.

Despite this, if she is successful in using her powers, she has shown to be extremely powerful. She was able to crush Touma's right hand as well as the invisible thing that came forth to attack her with strange ease.

Furthermore, as a god, she has territory over the dead, which allows her to turn Bersi into an Einherjar, though the process is unknown.
