Unlike Martina Navratilova, she is a character in the Slayers universe. The princess of the kingdom of Xoana, she is characterized by tending to fall in love several times in the course of a few episodes. She has otherwise still a volatile personality; for example, when Lina Inverse destroyed her castle (after Martina of course attacked first), Martina became set on her quest to destroy Lina.

Martina created her own god in the form of the monstrous Zoamel Gustav (aka Zoamelgustar), sometimes giving her strange powers. She is without a doubt the coolest character from Slayers Next (^_^). Her seiyuu is Hiiragi Mifuyu.
