One day Yuki finds a church. She sees a sculpture of Mary and thinks it looks like Mrs. Iwabuchi. The clergyman and his wife find out that the cross that Yuki has is that which Akarupa made for his daughter. Akarupa is an Ainu man who made the sculpture of Mary, too. Hearing about the sculpture from Yuki, Mrs. Iwabuchi asks Yuki how Akarupa lives.

In Hokkaido, Yuki and Ryuuta see Mrs. Iwabuchi and Akarupa talking. Akarupa has a gun. Yuki and Sanae finds an old photo. Mrs. Iwabuchi and Akarupa are in it with a baby. Seeing the photo of them together, Sanae passes out. Yuki thinks the baby could be herself. Mrs. Iwabuchi doesn't know Yuki is her real daughter until Ryuuta tells her.

When Mr. Iwabuhi and Yuki get lost in the snow, Ryuuta saves them. Ryuuta is Ainu and thinks that mainland Japanese people are invading Hokkaido and he hates it.
