Maria Bartlet, known simply as Maria in the Japanese version, is a primary level teacher at the Duel Academy in New Domino City, who teaches classes for child students. Among her students are Leo, Luna, Dexter, Bob, Patty and Sly. Miss Bartlet was against Heitmann when he wanted to expel her students regardless of his threat about telling the Chancellor that they weed out the faculty (because he thinks the students are terrible because of her). She became worried about Yusei Dueling Heitmann, knowing how strong his Deck is, but Akiza assured her that Yusei could win against him.
