Natsume overhears whispers that a powerful youkai is reviving, later that evening he is trapped in a bottle as an offering.  Humans can’t see or hear him, so Nyanko-sensei decides to help the “best” way he can…
so it's up to me whether 
I help him or not.
Ayudarlo sería mi decisión.
Así que es decisión mía si le ayudo o no.
então cabe a mim decidir se o ajudo ou não.
