Fantasy is one of the biggest genres in anime, so it has many sub-genres. There's a big difference when it comes between high fantasy and low fantasy, especially in terms of magic systems and world-building. High fantasy anime are titles like Yona of the Dawn and Nausicaa of the Valley of the Wind, and Kiki's Delivery Service represents low fantasy titles.
