Labyrinth Town is a fabled city made up of 10 districts that are home to both witches and diviners. Many teenage girls begin training in the maze's outermost district to join the ranks of the "Urara," a group of ladies recognized far and wide for their capacity to divine the solutions to the world's most challenging issues. Chiya, a mountain girl bred among the animals, is called to assume her due place as a first rank urara. She thinks that by joining them, she would be able to locate her long-lost mother.
