San rejects her own humanity and even thinks of herself as a wolf. San’s primary concern is protecting the forest and the animals she lives with. Moro raised San as her own daughter, and in turn, San treats Moro as her mother and Moro's two natural pups as brothers. San's parents threw her to Moro as a sacrifice to save their own lives. When San was a baby, the wolf goddess Moro attacked her parents, who were found damaging the forest. With the assistance of her two wolf brothers, she sets out to help the Boar Clan defeat Iron Town. San would do anything, even die, to get the humans out of her forest. As a child, she was abandoned in the woods by her parents, but Moro, the mother of the Wolf clan, took her in to raise as her own.

San, also known as Princess Mononoke, is the titular deuteragonist of Princess Mononoke. I'm not afraid to die! I'd do anything to get you humans out of my forest!
