On her way to school, Aoi, who can see ayakashi, encounters an ayakashi she's never seen and is abducted to Tenjin-ya, an inn in the hidden realm. There, she learns that her grandfather promised that she'd marry the master innkeeper to pay off his debt.
But I feel like I've seen him somewhere...
Aber sein Gesicht kommt mir bekannt vor …
Pero siento que lo he visto
en algún lado.
Je l’ai déjà croisé. Mais où ?
Mas sinto que eu já o vi antes.
