But "slow" doesn't last long when the fiercest fighters and boldest beauties of this matriarchal world start checking in... and checking him out! Between building the perfect inn and surviving as the entertainment for his rowdy residents, Shirou's new life is shaping up to be anything but ordinary in this sexy isekai romp.
