Maria

Likes: General housework, singing and karaoke, games (video games, chess, billiards), teasing people
Dislikes: Cockroaches

Maria is Nagi's maid and surrogate older sister/mother, both appearing and acting in a manner more mature than people typical of her age. Because of this, even people near to her speak of her as if she is older than she really is, a pet peeve for her. A phrase she commonly responds back with is "I'm still a fresh seventeen year old."

Maria is highly intelligent, somewhat devious, good at general housework and likes games of all kinds, though she's deadly afraid of cockroaches, which she refers to as "the dark life-form that exists in the kitchen and other places." She has also proved capable of self-defense techniques in times of need. Maria also placed her mark in Hakuou by being the youngest student council president at the age of 10 in her first year. Despite this, she has no clue about the "normal life."
