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!
That which shields me,
 reveal thy name.
Aquella existencia que me 
protege, muéstrame el nombre.
Ser que me proteges, muéstrame tu nombre.
Aquele que me protege, revela teu nome.
