**Maria Takayama** is an original character. She has light blond hair, long enough to reach her back and typically braided, with frontal sections extending to her chest and a fringe swept to her right. Her eyes are blue. Her attire consists of a dark stone blue gown covering her entire body, featuring white lace-type fabric inside. Accessories include a golden necklace with a large blue stone and light brown boots reaching her shins, laced criss-cross style. A hair ribbon and habit veil are consistent design elements.

Maria responds to inappropriate requests, like demands to see her underwear, with disgust. She initially excuses herself to confirm the request. After a pause, she rationalizes compliance, believing fulfilling the demand prevents the requester from succumbing to wickedness and evil. This reasoning leads her to reluctantly agree despite her revulsion.

During such interactions, she clutches the pendant around her neck, indicating internal conflict. She verbally expresses disappointment, calling the requester foolish. Her disgust manifests as a glare directed at the viewer. She ultimately displays her underwear while maintaining this expression of contempt.

Her name "Maria" carries Latin origins with meanings including "of the sea," "sea of bitterness," "drop of the sea," "bitter," "beloved," "rebellious," or "wished-for child." Her surname "Takayama" combines the Japanese words "taka" (高), meaning "tall" or "high," and "yama" (山), meaning "mountain" or "hill."
