NieA_7 Bath (Latter Part) - S1.E12

Kotomi has hired someone to fix the hole in the bath house roof. On her way to school Mayuko goes to the Alien Registration Office to see if there is any sign of NieA. They tell here that they have no information on anyone lower than an Under 5 classification. Later that day Mayuko gets a package from her mother. She says she cannot find any of the old notebooks that she used to write stories in but she did find some old pictures. The pictures show Mayuko and her family when they used to own and run the bath house. These cause Mayuko to get sad. Later, NieA has shown up out of the blue as if nothing has happened. When a storm blows through, Mayuko and NieA try to hold down the tarp over the semi-repaired roof. When they look up, they watch the mother-ship disappear in a sparkle of light.
