Maria is a female android created by Doctor Chaos, who combined long-lost magical arts with advanced technology to bring her to life. Designed in the image of Doctor Chaos’s lost love from his younger days, she serves primarily as his main weapon, bodyguard, and housekeeper. Maria is physically powerful, fast, and highly resistant to damage, and her body conceals an array of hidden weapons. Despite her mechanical nature, she is described as a kind-hearted person who possesses a genuine soul and a strong urge to serve mankind. She behaves in an obedient, helpful, and caring manner toward those she trusts. Her primary motivation is to serve and protect Doctor Chaos, though she also shows a capacity for independent emotion, as seen when she temporarily developed feelings for Tadao Yokoshima after being exposed to a powerful aphrodisiac, an effect that ceased only when she shut down. Maria is a supporting character in the series, and her role often brings her into conflict or collaboration with the main cast. She has pink hair and green eyes, and is typically depicted as an adult female. There is also a notable instance where Doctor Chaos, facing financial difficulty, used Maria as collateral for a loan to construct another android named Teresa, indicating the complex relationship between creator and creation. Maria does not undergo major character development across the story, but her presence highlights themes of loyalty, artificial life, and the blurred line between machine and soul.
