Christa Lenz, later Historia Reiss, is a petite young woman with long blonde hair and striking blue eyes. During her service in the 104th Training Corps, she stands out as the shortest cadet, typically wearing her hair in a practical ponytail and the standard green uniform. Upon ascending as queen, her appearance transforms: her hair is elegantly coiled into a pleat updo, and her wardrobe shifts to regal attire featuring a pale coat layered over a crimson jacket. Born the illegitimate daughter of Rod Reiss, patriarch of the influential Reiss family, she emerges as the sole surviving heir to their bloodline. After her mother’s demise, Rod obscures her identity under the alias Krista Lenz, conscripting her into the military with the expectation of her demise. Within the 104th Corps, she forges a deep bond with Ymir, another cadet. Graduating tenth in her class, she enlists in the Survey Corps, advancing her military career. As Krista Lenz, she cultivates a gentle, reserved persona, habitually prioritizing others’ perceptions of her virtue. This self-effacing conduct stems from internalized insecurity and a propensity for martyrdom. When truths about her lineage and the Walls’ secrets surface, she sheds her false identity, reclaiming her birth name and legacy as Historia Reiss. Her ascension catalyzes political revolution, toppling the corrupt monarchy and ushering in a new era of rule. Her journey intertwines personal evolution with the burdens of sovereignty, navigating themes of self-discovery, acceptance, and the complexities of wielding power.
