Chapter 10:
The Station Opening, the day when everyone in the city gets rid of what they don't need, begins, and a cup that is very important to Yase is thrown away.
Chapter 11:
Yase has lived her whole life surrounded by things that remind her of her mother, and Koto tries to get her cup back, but...
Chapter 12:
Koto tries to fix things between Kurama and Yase, and feels a connection to her mother between them.
This happens every time 
there's a station opening.
Das passiert jedes Mal,
 wenn die Station eröffnet wird.
Esto pasa siempre que hay 
una apertura de estación.
Es lo mismo de siempre cada vez 
que hay una apertura de estación.
Celle-là…
Sempre acontece isso quando
tem uma abertura de estação.
