Izumiko has lived a secluded, sheltered life in a mountain shrine since she was born. Having been raised to become the vessel of the Hime-gami, a mysterious force, the girl’s family has carefully planned and measured all aspects of her life - from the prestigious school she’s meant to attend to even her hair style. So when Izumiko is threatened by strange events, her father forces yet another obligation on her: Miyuki Sagara, a mountain monk descendant who’s fated to be her bodyguard. Unfortunately for the duo, neither is happy about the arrangement, especially Miyuki, who’s being exiled from his home city to guard a girl he considers to be useless. Can the two learn to find common ground in their search to understand the supernatural mysteries unfolding around them?
