Maria is a small girl around ten years old.
Ever since Maria witnessed Ramirez kill her father, she has been unable to speak. She lives with Doc on a little ship and has a little bird named Piccolo as pet. As Piccolo only eats Moonfish, Doc asks Vyse if he can bring Moonfish to Maria in order to feed Piccolo. After Vyse feeds Piccolo for a while and Piccolo transforms, she will speak and thank Vyse for his efforts.
After 24 Moonfish are eaten, Piccolo grows to a large size and leaves Maria. Following Piccolo's departure, Piastol comes to Maria, as they had been sisters and had both lived in Valua until the death of their father.
