But during the play, Nezumi has a vision of a strange wind and song and he faints on stage.

Safu has returned to No.6 because of her grandmothers' death. After she collects the last of her grandmother's things, she realizes that something is odd when her grandmother's knitting needles are missing.

After leaving Karan's bakery, Safu is abducted by the security bureau. Meanwhile, Shion and Nezumi continue their discussion over the future of No.6 and the parasite wasps.

Nezumi secretly requests that Inukashi obtain information on the correctional facility, giving a large sum of money as payment along with the promise to sing if Dog Keeper were to die. However, unbeknownst to Nezumi, Shion and Rikiga are visiting a used clothing store where Shion discovers Safu's coat that was smuggled from the correctional facility. Meanwhile, Safu is being treated as a "sample" by the researchers at the facility where she was taken. That night when Nezumi comes home, he sees that Shion has made a large supper. The two eat and Shion says he was happy...

In order to save Safu, Shion and Nezumi head to the edges of the Western District. There, they meet a legless old man who leads a large group of men.

He also states that Nezumi is the last survivor of the forest folk who were wiped out by No.6. After Nezumi has another vision with the winds and the singing like he had before while he was performing in his play, he repeats ...

Shion and Nezumi climb the huge pile of bodies where they were dropped in and infiltrate the facility searching for Safu. Meanwhile, Rikiga and Dog Keeper leave the baby Shion saved to one of the dogs and gain entry into the facility by themselves to clear a path for Shion and Nezumi. Somehow, Shion knows exactly where to go and where all the cameras are, and this makes Nezumi a bit suspicious.
