Mitsuha the Stream.

While wandering beside a peaceful river, a wizard named Mitsuhanmeoad encounters a troubled young girl named Florence. They decide to go to Florence's home at the edge of a forgotten village where Mitsuhanmeoad learns that Florence's family is affected by a strange curse. As secrets unfold and shadows from the past emerge, the wizard must navigate ancient magic, buried grief, and the strength of a child's hope to help Florence reclaim peace for her family-and perhaps, for herself.
