Meiro-chō is a town where all-female diviners (uranaishi) live and where girls from all over the country yearn to become the top diviner — "Urara." Today, a solitary girl named Chiya enters the town's gates. However, she has another purpose coming here, besides becoming the Urara. Chiya's days as an apprentice diviner begin as she meets three friends — the earnest Kon, Kōme who is a fan of Western culture, and the shy Nono.
