Soul is a wolf cub who is born in the midst of a battle. His mother runs to a cave and leaves him in the cave and goes back to fight. Soul then meets Ace, a 'teenage' wolf who has lived his whole life in the same cave and was abandoned there by his mom. Ace takes care of Soul and shares with him the secrets of the forest, teaches him how to hunt, fight, and use his creativity to make necessary things. Needless to say, they are great friends from the start.
