Sasha Kreuzhev

Sasha Kreuzhev (ステイル＝マグヌス) is a character introduced in Toaru Majutsu no Index. She is an operative of Annihilatus of the Russian Orthodox Church, which specializes in the hunting down of spirits that are not supposed to exist. Her form makes it's appearance early in the series during the Angel Fall Arc, however, her first actual appearance is seen much later in the series.

Appearance
Sasha can easily be distinguished by her signature look, a red hood and cape (which hides her long curly blond hair) and matching pointy red shoes. Her torso and limbs are covered with leather belts, and has metal braces on her ankles, wrist and waist, the latter being used to carry her many eccentric weaponry. Under is small layer of clothing that covers her torso and her arms up to the wrist, and acts like a thigh-high socks, they are form-fitting which naturally shows Sasha's figure.

Sasha's skimpy dress can be attributed to her female superior –Vassilisa –who forced Sasha to wear it as part of her hobby.

Angel Fall Arc
Her form first appears during the Angel Fall Arc, where the fallen angel – Michael – uses her form as a way to find the culprit of Angel Fall, under the name of Misha Kreuzhev.

After finding out that the culprit behind the spell was Kamijou Touma's father, she reveals herself to them and tries to use The Sweep to eliminate Touya. She is later preoccupied by Kanzaki Kaori while Touma and Touya find a way to end Angel Fall, and return the angel to heaven (which was actually confused by Kaori as Archangel Gabriel). After Tsuchimikado Motoharu destroys the ritual location of Angel Fall, the angel returns to heaven, though leaving a large amount of telesma as a consequence for him using Sasha's form.

Volume 12
It was noted that due to Angel Fall, there is a massive amount of "Telesma", the equivalent of mana for angels, left as residue in her as an after-effect of Gabriel's "possession" rivaling that of the Holy Mother. Though the real reason isn't known to her or anyone else of the Russian Orthodox Church, it resulted in her being put under observation for the time being.

Abilities
She carries around a large number of unique weapons from hammers to saws.
