Othinus

Othinus (オティヌス Otinusu) was introduced in Shinyaku Toaru Majutsu no Index and is a Magic God and the leader of GREMLIN. She is referred to as One-Eyed Othinus and, similarly to the Othinus (the Latin name for Odin) of legend, she wears an eye-patch over her right eye which she removed as a sacrifice in order for her to drink from the Well of Wisdom. It is the way she is dressed that would be later used as the basis for the appearance of Odin in 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 blond hair. 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 a ribbon wrapped around her. Traces of a witch-like design are present, such as the cape and a wide brimmed hat with a pointed tip. Touma had joked that her outfit isn't that different from how people depicted Odin outfit, wearing only pants and a cape. Initially, Othinus was depicted as 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. However, later in the series due to various circumstances she ends up in Touma's care and is shown to be quite open in humoring his personality. However, she doesn't suffer fools lightly and can be quite violent when annoyed by him too much, though this has no effect on Touma as he enjoys it. She acts serious and levelheaded, making her the straight-man to Touma's wise guy. Both Touma and Thor have noted that Othinus likes to explain things.
