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!
Whenever I meet a youkai like this, who seems free,
Esto pasa cuando me topo con un ayakashi
Siempre ocurre igual cuando encuentro un ayakashi
Sempre encontro youkai que parecem livres, mas 
carregam um pesado fardo em seu coração.
