Princess Mononoke- Good Friends, Better Enemies

Following a tense twenty weeks, Ashitaka and San now live together in the forest with her brothers. Only a few months into Ashitaka's stay, her brothers become weak to the point where they can barely stand. Lady Eboshi informs them that San's brothers are dying, but there's one thing that can save them. But there's a catch: Lady Eboshi will have to bring them to that one thing.
