Maria

マリア

Maria serves as Nagi's maid and acts as a surrogate older sister and mother, displaying a maturity in both appearance and behavior that exceeds what is typical for her age. Consequently, even those close to her refer to her as if she were older than she actually is, a habit that irritates her. She frequently counters this by stating, "I'm still a fresh seventeen year old."
She possesses the most common sense among the characters, although her understanding of monetary value is as poor as Nagi's. She appears to manage all affairs within Nagi's manor, as everyone from the head butler to the SP either obeys or fears her, or both in certain instances. Maria is highly intelligent, somewhat devious, skilled in general housework, and enjoys various games. However, she suffers from Katsaridaphobia, a severe fear of cockroaches, which she describes as "the dark life-form that exists in the kitchen and other places." She has also demonstrated proficiency in self-defense techniques when necessary. Conversely, she is inept at disguises, as evidenced by multiple occasions where she attempts to spy on Hayate and Nagi only to be recognized immediately. Maria made her mark at Hakuou by becoming the youngest student council president at age 10 during her first year. She is one of the few individuals noted to be smarter than Nagi, which is why Nagi appointed her as her sole maid. Maria initially began as Nagi's tutor. Despite her high intelligence, she lacks understanding of "normal life." For example, in the manga, she was unaware that trains other than bullet trains exist.
