Aoi Kururi is an onmyōji enrolled at a private academy, where he specializes in the study of scents. Though he harbors a deep aversion to using onmyō magic, his reluctance is put to the test when a mysterious curse falls upon his entire class, compelling everyone to lose control of their bladders. To his surprise, the warm sensation and sweet fragrance of the girls' urine amplify his magical abilities, allowing him to break the spell and rescue his classmates. Thus begins a series of bizarre misadventures involving Aoi, his sisters, and his circle of friends.
