Hinako, Kana, and Wakaba are three high school girls and the best of friends. One day they're goofing around at a shrine taking photos, and accidentally break a seal and release 108 spirits that had been sealed there. These spirits are terribly mischievous, and even turn one of the girls' classmates -- who was with them taking the photos -- into a strange mystical gem! The old man who watches over the shrine confronts the girls, telling them that it's their fault that the spirits escaped. They are each granted a secret transformation power that allows them to fight the sprits, and now it's their responsibility to capture the spirits and seal them back up again.
