The Faraway Paladin anime
A city that is dead and buried, long abandoned and far from civilization, dwells one child of humankind, his name is Will and he’s brought up by the brave bone-scarred warrior Blood and the elegant sainted priestess Mary and the scruffy psychic sorcerer Gus. The three pour their love into the boy and they teach him everything they know about.
One day, Will begins to think: “Who am I?” Will must uncover the mysteries of this distant dead man’s land and discover the hidden past of the dead. He will learn about the compassion and mercy of the gods, as well as the bigotry and insanity of the bad. Once he has mastered everything, the young man will be able to take the first step to become the Paladin.
