Lieutenant Aria Gartland of the Seventh Holy Knight Corps serves under Commander Hewie Elzard, her violet hair styled in sharp spiky bangs framing piercing blue eyes and a pale, slender frame. Her militaristic attire—plate armor layered over a sleeveless leotard, a cape flaring behind her, fingerless gloves, and thigh-high stockings—blends battlefield pragmatism with disciplined elegance. A tsundere at heart, she enforces rules with a fiery temper, berating allies like Hewie for perceived recklessness, yet conceals a steadfast commitment to ending the war swiftly, driven by an unspoken dread of bloodshed.

Trained in military strategy, she pores over tactical manuals but falters in kitchens, her culinary failures fueling quiet insecurity beside peers such as Hannah Hamilton. Though she wields a sword with precision—occasionally a katana for specific missions—her battles extend beyond combat: clashing with Hewie’s unconventional tactics before gradual trust emerges after he saves her from the Black Knight’s brink, cracking her stern facade to reveal fears of his loss.

Haunted by ghosts and the prospect of lifelong soldiering, she yearns privately for peace to shed her armor, torn between duty’s call and a future unchained from war. Her rivalry with Hannah and mentorship of junior knights underscore a rigid yet compassionate leadership, navigating war’s moral shadows while clinging to honor, loyalty, and the fragile hope of a life beyond the battlefield.
