Meiro-chou is a town where all female diviners (uranaishi) live. Here they prepare and train, hoping to become the top diviner-Urara. A solitary girl named Chiya enters the towns’ gates. However, she has another purpose in coming to Meiro-chou, in addition to becoming the Urara. See Chiya’s days as an apprentice diviner begin, along with her new friends-the ernest Kon, Western culture loving Koume, and the shy Nono.
