Misha Kreutzev represents the temporary identity assumed by Archangel Gabriel while possessing Sasha Kreutzev, a female operative of the Russian Orthodox Church's Annihilatus organization tasked with eliminating anomalous spiritual entities. Occasional confusion arises from the unisex diminutive "Sasha" and romanization inconsistencies in her surname. Sasha possesses long curly blond hair, typically hidden under a red hood and cape, and wears pointy red shoes. Her distinctive attire, forcibly imposed by her superior Vasilisa, includes leather belts binding her torso and limbs, metal braces on her ankles, wrists, and waist for carrying weapons, thigh-high stockings, and minimal clothing that exposes her figure. Her bangs often obscure her eyes, and her physical appearance suggests an approximate age of 13. Sasha employs a formal speech pattern structured around numbered statements like "My first question:" or "Supplementary explanation:". She exhibits a preference for brandy during work hours and expresses an aversion to luxury foods like sweets, though this temporarily altered during Gabriel's possession. She maintains loyalty to the Russian Orthodox Church but displays discomfort regarding Vasilisa's eccentricities. Sasha serves under Vasilisa in Annihilatus. During the Angel Fall incident, Archangel Gabriel descended and appropriated Sasha's form, adopting the alias "Misha Kreutzev" – derived from "Mikhail" (the Russian equivalent of Michael) due to a distortion swapping Gabriel's elemental alignment with Archangel Michael's. As Misha, Gabriel assisted Kamijou Touma's group in identifying Angel Fall's perpetrator while seeking to return to heaven. This possession left residual angelic telesma within Sasha's body, comparable to the Holy Mother's capacity, resulting in extended surveillance by the Russian Church. The telesma residue made Sasha a target. When the Russian Church ordered her capture, Vasilisa renounced her allegiance and aided Sasha's escape. Vento of the Front sheltered Sasha and guided her to the Elizalina Alliance of Independent Nations for sanctuary, arguing her presence might deter indiscriminate Russian attacks. During the escape, Sasha discovered and rejected replacement clothing provided by Vasilisa, which resembled a magical girl costume. In the World War III arc, Fiamma of the Right captured Sasha to exploit her residual telesma, which retained Michael's attributes due to the earlier distortion. This enabled Fiamma to manipulate Gabriel (conceptually linked to Sasha) through the Star of Bethlehem. Sasha later collaborated with allies to disrupt Fiamma's control circle, facilitating Touma's confrontation with Fiamma. Following these events, Sasha resumed duties alongside Vasilisa as a bodyguard for Russian Patriarch Krans R. Tsarskiy. She participated in the Anti-Gremlin Alliance conference in New York, chastising Vasilisa for cultural interests potentially conflicting with Church doctrine. While inhabiting Sasha's body as Misha, Gabriel demonstrated abilities including water manipulation (Water Snake, Water Wing), celestial control (Astro In Hand to alter day/night cycles), and large-scale purification spells (God's Purge/Sweep). Gabriel also adopted Sasha's speech patterns during this possession. These powers ceased when Gabriel relinquished Sasha's form.
