Shrine of the Morning Mist (朝霧の巫女, Asagiri no Miko?) is a manga and anime series in the modern fantasy genre that delves heavily into the practices and beliefs of Shinto. It was written and drawn by Hiroki Ugawa and was published in Shōnen Gahosha's Young King Ours. In North America, the manga and anime are licensed by Tokyopop and Media Blasters, respectively

It tells the story of Yuzu Hieda, a high school freshman and one of three sisters, all of whom are miko at the local Shinto shrine. When her childhood love returns, it is discovered that dark gods have a great interest in him and Yuzu is recruited to gather fellow female students into a "Miko Council" to fight off a full-scale mystic assault.

The priestesses have talismans which focus their powers and are used when attacking the dark kami.
