Cross Marian (クロス・マリアン , Kurosu Marian ) was an Exorcist and General of the Black Order. Though technically a member of the European Branch, he was notorious for disappearing for years on end and expressed a great disdain for returning to Headquarters. He was the master of Allen Walker, and one of the only people who knew of Mana Walker's true intentions concerning the boy. Cross was the leader of Marian Unit.
