Kilmaria, known also as Kilmaria of Corruption, began as one of the Demon King's six demon generals. Her betrayal of the Demon Lord army commenced when she killed Malvekanth, an underling of fellow general Woodvoss, marking her departure. This act stemmed from dissatisfaction at the lack of worthy opponents and waning interest in the army's objectives. Her narrative centers on a transition from antagonist to anti-heroine, increasingly aligning with former adversaries for personal reasons. Her distinct appearance features messy spiky brownish-black hair, silver eyes, twin horns, and pointed ears. She typically wears a revealing purple Chinese-style dress adorned with a dragon motif, exposing her cleavage and midriff, complemented by a yellow ascot, white fur-trimmed jacket, black stockings, and boots. When disguised as a human, she magically conceals her horns and alters her ears, adopting smoother hairstyles and human attire like a blue-and-white villager's dress with a yellow scarf. Her beach attire consists of minimalistic clam-themed garments emphasizing her voluptuous figure. Kilmaria's personality combines misanthropic contempt with fierce honor and an unrelenting pursuit of challenging battles; she disdains fighting the weak. After encountering Maya Ikusaba—a warrior matching her strength—she develops an intense rivalry, constantly seeking rematches. Interactions with Maya's brother, Asahi Ikusaba, trigger significant development: she gradually forms romantic feelings for him, leading to protective behavior and further betrayals of the demon army to support him. Alcohol exacerbates her perverse and childish tendencies, particularly in displays of affection toward Asahi. She wields formidable abilities befitting her former status: - Immeasurable Strength, enabling effortless one-hit defeats of high-level monsters and adventurers. - Immeasurable Speed, allowing her to match Maya’s movements. - Immeasurable Durability, resisting significant physical and magical assaults. - Immeasurable Magic, specializing in destructive spells and barriers, alongside shapeshifting for human disguises. - Flight proficiency, demonstrated through skilled aerial maneuvers. Key relationships define her arc: - With Maya Ikusaba, she maintains a fierce rivalry fueled by mutual strength and frequent clashes, respecting Maya’s heroism. - With Asahi Ikusaba, she evolves from curiosity about his rumored power to genuine romantic attraction, often acting possessively or perversely around him; she notably intervened to protect him during a confrontation with Gloria. - With Gloria, she incites envy over her breast size and intercepts threats toward Asahi, including incinerating a necromancer who insulted him. Her dynamic with Kuon is noted as a "good friend" connection without deeper elaboration.
