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…
When you come home,
 make sure you eat
Así que cuando regreses come 
bien y cierra bien la casa.
Cuando vuelvas, cena en condiciones y echa la llave.
Quando voltar, não esqueça de comer e de trancar as portas.
