A housemaid for the Sanzenin family. Highly capable in everything she does, from housework to video games. Likely because she's surrounded by people who are always goofing off, she has also developed a reputation for her sharp wit. Her dream is to see her reclusive young mistress grow into a respectable citizen.
Maria is the Nagi’s personal maid and quite possibly the only sane person in the entire series. She also appears to be the head maid of the entire manor as everyone around her treats her with the utmost respect (and sometimes fear). Like any good housemaid she’s efficient at all of her duties and can even guard Nagi if the need calls for it, though it’s best not to mention cockroaches when she’s around. She’s quite aware of Nagi’s affection towards Hayate and isn’t above trying to spy on the two, often with extremely poor disguises.
Does she have a crush on Hayate as well? Considering the kind of series we’re dealing with here, I wouldn’t be surprised if she did. However, she often takes the role of a motherly elder sister to both Nagi and Hayate and does whatever she can to ensure their happiness. Though Maria has proven several times to be highly intelligent, she’s absolutely clueless when it comes to normal life outside of the mansion.
