Maria possesses medium-length burnt orange hair, accented by a single braid along her right side, and golden-brown eyes. Her attire consists of a red-and-white maid uniform, white pantyhose, and black shoes, crafting an image of poised elegance that belies a history marked by hardship.

Born in a village ravaged by thieves, Maria endured enslavement alongside other survivors before being sold to a slave broker. There, she mastered household management, literacy, and combat until her acquisition by the Mulan Trade Company. Assigned to serve Takumi Iruma, she transitioned from servitude to structured independence as his household manager.

Once withdrawn and burdened by self-doubt, Maria cultivated a vibrant, socially engaging demeanor, becoming a unifying presence among peers. Her relentless commitment to domestic excellence occasionally spiraled into harsh self-criticism—once comparing herself to a "toilet" over minor failures—yet she matured into a composed A-rank adventurer, seamlessly blending combat prowess with meticulous homemaking.

Her bonds include a steadfast friendship with Sofia Sylphid, an elf adventurer, and a transformative relationship with Takumi, evolving from professional contract to marriage rooted in mutual respect. Her traumatic enslavement fuels her advocacy for others trapped in bondage, driving her to champion their liberation.

Proficient in advanced household logistics, tactical combat, and alchemical tool utilization, Maria’s journey—from traumatized survivor to assured adventurer and partner—exemplifies resilience nurtured by supportive alliances, underscoring her adaptability and enduring pursuit of growth.
