This anime strongly reminds me of xxxHolic's adventures, where the female powerful character resembles a goddess and solves the problems and wishes of others, with limits based on the story's reality.
Both series portrait strong female protagonists and mystery solving, with a wonderful and powerful storytelling based on myths, religion and gods. They also portrait spirits and supernatural entities.
