As with its prequel, Zoku Natsume Yuujinchou is about Takashi
Natsume, a boy who has had the ability to see youkai since he was young,
and his bodyguard youkai Madara, nicknamed Nyanko-sensei. Natsume
attempts to return names written in his "Book of Friends" (which he
inherited from his grandmother Reiko) to youkai in his village.
Throughout these adventures, he meets some youkai that are friendly,
some that want to steal the Book, and some that want to kill him, as
Natsume learns about himself and his relationship with these mysterious
beings along the way.
