Aki Yukimura, alternatively called Akie Yukimura, hails from a secluded mountain village nestled in Japan's forested highlands. After years serving as a maid in Tokyo, she returns to her birthplace and rekindles ties with Yuuta, a childhood companion with whom she once roamed fields and lakes. She playfully establishes a maid-master dynamic, addressing Yuuta as "goshujin-sama," which revitalizes their bond while weaving new tensions. Though she acts sisterly toward him and shares physical closeness, her true motives remain veiled. She genuinely harbors romantic feelings for Yuuta yet conceals crucial details, particularly about an encounter with an unnamed wealthy man during a village festival. Her evasive answers and feigned ignorance about this man inject secrecy and jealousy into their relationship.

Polite, friendly, and modest—traits honed through her profession—Aki endears herself to villagers with her warm smiles. Occasional clumsiness in her duties sparks self-doubt about her suitability as a maid. Yuuta refers to her as "Akie-nee," indicating a familial bond as a relative, likely an older cousin figure, though the exact kinship is undefined.

Aki possesses dark purple hair and ochre eyes. Her narrative revolves entirely around her homecoming and evolving interactions with Yuuta within the village, confined to the original OVA timeframe without resolution of her concealed secrets or emotional conflicts.
