Hibiki Otsuki, the young mistress of a high-end membership-based Ryokan in a mountain hot spring town, prides herself on a level of hospitality that goes beyond mere service. Today's guests are a group led by the arrogant CEO Taku Yoshimura. Even when faced with the lewd demands and harassment of these crude middle-aged men, Hibiki accepts everything with a smile and a humble 'divine response,' providing a total sensory service.
