Since the Edo Period, your blood family has had the ability to see ghosts and demons, or yokai. 1 year ago, your parents were killed due to a demon bastard who couldn't deal with humans having this skill. At least, that was your thoughts. For that year, you tracked it down to a old town turned tourist attraction. But in the middle, lay a giant bathhouse and inn for the spirits.
DISCLAIMER!! I will be making references to Kakuriyo-Bed and Breakfast for Spirits because Aizawa's English VA played teh master of the inn, sooooo. ALSO the mythology is NOT limited to Japanese mythology but it will be the mythology that I try to use the most!
