Kakuriyo no Saiyaku to Utsushiyo no Ikusabime ~Kirie Hen~

Synopsis

In modern times, in a certain provincial city--- Tachibana Kirie, daughter of the chief priest at Oyama Shrine, and Kurahashi Makoto, who's training as a live-in apprentice at the same shrine, find themselves facing a bizarre phenomenon.

People are suddenly losing consciousness and not waking up - an unexplained "Sleeping Sickness." Even Kirie's parents have fallen victim to this strange illness spreading through town.

By chance, Kirie and Makoto meet a black fuzzy ball that calls itself a god, who informs them the "Sleeping Sickness" is the work of beings from the hidden world - youkai, gods, and other supernatural entities.

The only ones who can oppose these beings are onmyouji with demon-quelling powers. Whether by fate or coincidence, Kirie - who possesses these powers - hesitates but ultimately resolves to fight.

"I'm gonna beat those youkai and get rid of this 'Sleeping Sickness'!"

But to use her demon-quelling powers, she needs to... do lewd things with a man. Kirie asks Makoto for help and prepares to get intimate. Now armed with her full exorcism powers, Kirie stands ready to battle the beings from the world beyond human knowledge...
