Maria

Serving as Nagi’s devoted maid and surrogate maternal figure, this seventeen-year-old possesses a maturity that often leads others to mistake her for an adult. Though she manages the manor with unmatched intelligence and authority, she lacks any grasp of "normal" life and shares Nagi's reckless spending habits. While highly capable in housework and self-defense, she harbors a paralyzing fear of cockroaches and struggles with failed undercover spying attempts.
