Miyoi works at Geidontei, a Japanese-style pub (izakaya) in a remote part of the fantasy land, Gensokyo. She is charming, loved by all customers including drunk people. Sometimes, those who are not human also come to Geidontei for a drink. A ghoul, a tanuki, a demon...all cute girls, but have special powers. Miyoi tries to solve mysteries that troubles the village with help from some of them...but she herself is one of the mysteries!
