Mazuurek holds the title of Count as a member of the Orbital Knights. He pilots the Martian Kataphrakt Sirenum.

Though he holds no contempt over the people of Earth, Mazuurek merely wants its resources and prefers not to fight. He apparently became interested in Earth because his name sounded similar to a Polish folk dance, Mazurka (pol. Mazurek), which is why he has come and wants to learn more about Earth.
