Othinus

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

Etymology
Her name, Othinus, is the Latin name for Odin, the Norse god 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 Well of Wisdom.

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 Gesta Danorum, Odin was exiled and Ollerus was chosen to take his place. This can be presumed why Ollerus currently has the Hliðskjálf.

Othinus would later attain the legendary title of Majin from Ollerus, which Ollerus proclaims to have been stolen from him, making him one of the most powerful beings in the Toaru Majutsu no Index storyline.

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.

Natural Selector Arc
After Kihara Kagun's death, Marian Slingeneyer swears to avenge him and prepares to unsheathe Dáinsleif, the harbinger of Ragnarok. 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 clean off.

Abilities
Mostly unknown, but it can be assumed that she has great magical powers, being a Majin, and is able to go toe-to-toe against Ollerus. It can be assumed that she also knows how to wield Gungnir more effectively than even Brunhild.
