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!
So you're the one who 
faked Touko-san's voice?
¿Fuiste tú quien imitó 
la voz de Touko-san?
¿Has sido tú quien ha imitado la voz de Touko-san?
Então foi você que imitou a voz da sra. Touko?
