Mitsuki, an only child at a Shinto shrine, grew up across the street from Kakeru, the son of a priest. They never got along growing up, and still don't as teenagers. However, a strange encounter with a demon seals their fate forever: the pair discovers they are the descendants of priests who sealed away disorderly demons. With the demons becoming a problem again, Mitsuki and Kakeru must inherit the mission of their ancestors - and somehow get over their mutual dislike for each other.
