After entering the outside world for the first time, Sana arrives at the bustling district of Kabukicho in Tokyo's Shinjuku Ward. In a convenience store there, she meets Kashimura Zoroku, the quintessential "stubborn old man."

Minnie C and her group took advantage of a moment's negligence to kidnap Sana. Left behind at his office, Zoroku demands answers from Naito as to just what Sana really is.

When Sana and Zoroku are loaded onto a cargo ship, the ones who appear to rescue them are Cabinet Information Research Office agents Ichijo Shizuku and Yamada Noriko.

The seasons have quickly turned to winter. The matter of the research facility has been resolved, and life is normal again in Zoroku's household. Sana seems to have fully adjusted to being a member of the Kashimura family, as well.
