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.
Looks like we can be certain that
Yahiko grew because of this mud, too.
Yahiko ist mit Sicherheit
auch durch den Schlamm gewachsen.
Está claro que Yahiko
creció por culpa del lodo.
Au moins, on a la confirmation
que le problème vient de cette boue.
Yahiko definitivamente cresceu
 por causa da lama também.
