After Natsume returned Amana’s name, she accused him of stealing her ring.  He has three days to find and return it before she burns down his house.  To make matters worse, the ring is trapped in the hair of a migratory youkai, and Nyanko-sensei is unable to use his powers.

estão sempre famintos e devoram tudo o que encontram.
