Sasha Kreuzhev

Sasha Kreuzhev is a Russian battle nun of Annihilatus who first "appeared" as Misha Kreuzhev in Volume 4 and, with her form assumed by the archangel Gabriel, the primary antagonist of the Angel Fall arc in Toaru Majutsu no Index.

Her appearance was used by the archangel Gabriel under the pseudonym Misha Kreuzhev when the spell Angel Fall was activated.

In 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.

In the same volume and Volume SS1, it was mentioned that her clothes were skimpy under the cloak because of the hobby of her female superior, Vassilisa, who forced it upon her with the excuse that it's a binding spell to bind herself as a last resort if a demon possessed her in the course of their work in Annihilatus of banishing supernatural spirits that shouldn't exist. In reality, Vassilisa only forced it upon Sasha as part of her hobby, once trying to force a cosplay of "Magical Girl Kanamin", one of Academy City's anime for kids, onto Sasha as well.

Abilities
She carries around a large number of unique weapons from hammers to saws and can manipulate water. Under 'God's Power' possession she can use incredible powers far greater than most other characters from the series.
 * Water Wing Capable of destroying a mountain with a single swing.
 * God's Purge Can turn half of the earth into ashes upon finishing the chant.
 * Judgment Summons burst of lightning bolts within her vicinity.
 * Astral In Hand 'Destroys' the Earth by stopping its natural rotation. This halts aqautic movement in oceans and funnels most of the water towards the North and South poles. With little to no water in the equator and surrounding longitudes, the 'sea level' becomes non-existent and deprives natural land heights of oxygen, as well as removing precious ozone higher up. Without a barrier from solar radiation in the area, the equator becomes inhospitably hot and dry. North and South poles become a bulge of slowly-evaporating water while incredible heats in the equator shift deep rifts and cause sporiadic and powerful earthquakes.
