High school girl Aoi Mashiro has begun her part-time job at the antique store Kura in Kyoto's Teramachi-Sanjo shopping district. There, she works with the store owner's grandson, Kiyotaka Yagashira. Kiyotaka is a young Kyoto man with a gentle demeanor—as well as a fearsome intuition and a bit of a wicked streak.
One day, a first-time visitor brings a tea bowl for Kiyotaka to appraise. Kiyotaka immediately identifies it as a fake. Then he and Aoi encounter a priest who introduces himself as Ensho. This man turns out to be an extraordinary counterfeiter. The mysteries continue in Volume 2 of Holmes in Kyoto!
