When Nanoka is transported back in time to a supernatural early 20th century, she gets recruited by aloof exorcist Mao. What thread of fate connects them? Together, they seek answers...and kick some demon butt along the way!

Nanoka, Mao, and his helper Otoya investigate the strange cult of Priestess Shoko in hopes of bringing her to justice, but cursed dolls and scrolls of eternal life may be more than they bargained for. Will the priestess's doomsday prophecy come true? Back in the present, Nanoka and friend-zoned Shiraha do some historical research that uncovers a cataclysmic event yet to occur in Mao's timeline. Then Mao's curiosity gets him on the wrong side of a group of bloodsuckers and in need of a rescue by Nanoka--again!
