Sasha Blouse hailed from Dauper Village, a rural settlement in Wall Rose's southern territory. Food scarcity caused by refugee influxes after Wall Maria's fall shaped her upbringing, fostering compulsive eating habits developed through hunting. This earned her the "Potato Girl" nickname after she stole a potato on her first day with the 104th Training Corps, offering a portion to instructor Keith Shadis as justification. Initially embarrassed by her rural Kyushu accent, she concealed it with overly formal speech, a habit Ymir criticized. Before enlisting, Sasha resisted refugees encroaching on her village's hunting grounds, opposing her father's suggestion to convert forests to farmland. This disagreement drove her to join the military. She ranked 9th in the 104th Training Corps, displaying exceptional intuition and situational awareness despite perceptions of her as eccentric and unsuited for group operations. Her hunting background granted proficiency with bows. During the Battle of Trost District, Sasha saved Samuel Linke-Jackson from falling off Wall Rose following the Colossal Titan's attack. Later stranded with depleted omni-directional mobility gear fuel, she joined Mikasa Ackerman's charge to reclaim headquarters but faltered in the supply room, requiring rescue. In the Clash of the Titans arc, defending her village during Wall Rose's breach, Sasha rescued a child named Kaya from a Titan using only a bow and arrow. This act led to Kaya's adoption by Sasha's father and marked her first confirmed Titan combat action. Sasha joined the Survey Corps. By 854, she transitioned to a sharpshooter role, adopting shorter hair and utilizing rifles. She acknowledged to Jean Kirstein that killing enemy soldiers had become easier. However, during a raid in Marley, she hesitated to shoot child soldier Gabi Braun, unable to target civilians. This hesitation resulted in her death when Gabi retaliated. Her death profoundly impacted allies; Niccolo, a Marleyan chef who bonded with Sasha over their shared passion for food, later confronted Gabi, recounting how Sasha "saved him from war" by inspiring his culinary purpose. Sasha maintained a close friendship with Connie Springer and mentored Kaya, who aspired to emulate her. Her gluttony remained a consistent trait, with no recorded food dislikes. Though initially intended to die earlier, her role expanded to include significant moments in later arcs.
