When Ashiya and Abeno smell a yokai on the potatoes Yahiko has been sneaking, they head to the farm where they were grown. There they encounter a yokai calling himself Nobou. Nobou has been attempting to leave the farm, but each time he does, he is enveloped in a strange smoke, forced to witness the events of his past, and returns to where he started. Nobou asked to be exorcised so he can leave the farm, but Abeno notices something about the situation.
Then the cause might be at the farm 
where these were grown, right,
Dann liegt das ja vielleicht
an dem Acker, wo sie begraben waren?
Pues la causa debe estar
en el cultivo donde crecieron.
Alors, le problème vient
peut-être de ce champ, Abeno.
Então pode ser que o motivo esteja nessa
 fazenda onde as batatas cresceram.
