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.
The Station Opening is how you 
get rid of your trash, right?
Die Eröffnung der Station ist
 euer Weg, Müll zu beseitigen, oder?
La apertura de la estación es como 
se deshacen de su basura, ¿no?
Con la apertura de la estación os 
deshacéis de la basura, ¿verdad?
Vocês se livram do lixo através
da Abertura de Estação, não?
