Free referred to as The Man with the Demon Eye while he was in prison, is a Werewolf from the Immortal Clan. Free is the first and only Immortal in the entire Soul Eater series, and usually proclaims his immortality to his fighting opponents. He is also the first character introduced with a Mixed Soul, as he is part Human, Witch, and Werewolf. Free was imprisoned for so long that he forgot his own name, and when Eruka Frog helped him to escape, he took the name Free as he was now "free."
