Based on the book Ronia the Robber's Daughter by Swedish author Astrid Lindgren, the series will be directed by Goro Miyazaki (Tales from Earthsea and From Up On Poppy Hill). The series will be animated by Polygon Pictures in conjunction with Studio Ghibli and will be 3D CG. It will be Studio Ghibli's first anime series.
The story is of a little girl named Ronia, the daughter of a colourful robber chieftain who lives in a castle high on a rock in a dark pine forest. She gets to know the creatures of the forest, meets another kid like herself, and questions her father's life of robbery.
Goro Miyazaki stated that, "Ronia the Robber's daughter is a story not just about a girl who grows into adulthood, but it is also a story about the love and growth between a parent and a child, and a story about the bonds between friends. My goal is to create a work that everyone, from children to adults, will be able to enjoy."
It will premiere in Japan this Fall.
