Z

Z is the nickname for Z&acirc;m&icirc; Yahy&acirc; Ahmad ibn Sulim&acirc;n al-Sinh&acirc;j&icirc;. He is a long-time friend of Gilgamesh Wulfenbach from shared schooling on the Castle Wulfenbach.

Z is a younger son of the Iron Sheik, best known to Europans from the popular story, "The Heterodyne Boys and the Race to the West Pole". He was sent to learn from the Baron because his father thought it would be a good experience for him, unlike some of the other students, who were "hostages" for their parents' good behavior. He makes friends with Agatha when she is brought on board the Castle.
