A youkai from Natsume past has found him and memories of living with relatives before the Fujiwaras are explored.

Natsume continues to spend his days giving back Youkai their names from the book of friends. One day, as he's heading home, he finds himself chased by a giant, rolling pot. The youkai in the pot insists that his grandmother Reiko stole a doll from her. When she threatens to hurt his family, however, he's forced to go out and find it. But would his kind, smiling grandmother Reiko really steal a doll from someone?

Natori's group searches the Hakozaki mansion for the study. But other forces want the powerful magics contained within, and Natsume doesn't want them to have it...
