Who is Mary Sioux?
Mary Sioux is part of the aired Saga of Tanya the Evil TV cast through Season 2 Episode 6 plus the movie. They matter because this show is a second-life story with a salaryman mind, a child body, and a war that treats people as inventory — not a HUD. War is labor. If you arrived from a review name-link, this page is the character stop — not a full episode recap.
Start at Episode 1 if you have not watched. Heavy Arene / movie / eastern-front talk sits behind the spoiler mark below.
Personality
TV Tanya writes people as jobs under pressure: rank, doctrine, computation jewels, and whether they treat Tanya as a prodigy, a monster, or a useful weapon. Mary Sioux reads through that lens. The show is not subtle about how ugly that math gets. That is the point.
Powers & skills
Aerial mage doctrine and computation jewels are public crafts. Being X’s bargains are not. If Mary Sioux is a fighter or mage, treat their kit as what an Imperial staff officer can measure. Type 95 miracles, Mary’s faith, and later eastern-front reveals stay spoiler-marked after Season 1’s Rhine opening.
Role in the story
Mary Sioux is supporting cast in the 203rd / staff / enemy map around Tanya. Season 2’s eastern front and the movie’s Moskva raid change how a lot of these people look at her. This page does not invent unaired Episode 7 fights.

Best moments
Look for the scene where Mary Sioux either flies with Tanya, fears her, hunts her, or signs her next posting. Those beats do more character work than a mage stat card.
