"Fox Grove", one of Japan's premier hot spring inns. The source of its hot springs flows through a parallel dimension that is the homeland of youkai. Consequently, the entire inn area suffers from dimensional instability.

The yokai cannot maintain physical forms and wander in a soul-like state, sometimes causing mischief to the inn's guests... Therefore, it had become customary at this inn to perform a ritual once a year to appease these youkai.

And now, that time has come again this year. This time, it seems a newcomer “Pacifier (Puppeteer)” will perform the ritual, causing some unease. Unexpected incidents during this ritual are not uncommon.

Will this new Pacifier (the protagonist) be able to successfully pacify the youkai?
