Labyrinth Town is a legendary city made up of ten districts, inhabited by both witches and diviners. In the outermost district of this maze, many young girls start training to join the "Urara," a group of women famous for their ability to divine answers to the world's most difficult questions. Chiya, a wild girl raised among animals in the mountains, is invited to take her rightful place as a first-rank urara. By joining them, she hopes to divine the location of her long-lost mother. Chiya quickly makes three friends: the studious Kon Tatsumi, the aspiring witch Koume Yukimi, and the reticent Nono Natsume. Armed with only their own ingenuity and a vague connection to the gods, they begin their journey in the way of the urara.
