Natsume is at home early one evening when he hears a knock on the door.  He sees Tohko outside, asking to be let in.  But when he opens the door, there's nobody there, and a gust of wind rushes past.  Another Youkai is after the book of friends!
It was a dream.
¿Qué? Fue un sueño.
¿Qué? Pero si fue un sueño...
Era só um sonho.
