Kakuriyo no Saiyaku to Utsushiyo no Ikusabime ~Kirie Hen~

In a modern provincial city, Tachibana Kirie, daughter of the chief priest at Oyama Shrine, and Kurahashi Makoto, a live-in apprentice, face a strange epidemic: a 'Sleeping Sickness' causing people to suddenly fall into comas, including Kirie's parents. A mysterious black fuzzy ball claiming to be a god reveals the illness is caused by beings from the hidden world—youkai, gods, and spirits. The only ones who can oppose them are onmyouji with demon-quelling powers. Despite her hesitation, Kirie resolves to fight: 'I'm gonna beat those youkai and get rid of this Sleeping Sickness!' But her powers require her to engage in intimate acts with a man. Turning to Makoto, she steels herself for the lewd necessity, and with full abilities unleashed, battles the supernatural threats.
