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.
Besides, marrying an ogre?!
I don't want to no matter what!
Und dann auch noch einen Oger!
Völlig ausgeschlossen!
Además, ¿casarme con un ogro?
¡No lo haré, no me importa la razón!
Qui plus est, épouser un démon,
Além dos mais... casar com um ogro?
Eu não quero, não adianta insistir!
