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.
And for some reason I'm the one 
stuck dealing with them all the time.
Und ich bin es, der sich um sie kümmern muss.
y por alguna razón soy el que se ha 
quedado lidiando con ellos todo el tiempo.
Y por una razón que todavía no comprendo, 
soy yo a quien le ha tocado pringar con ellos.
et je me fais toujours avoir.
E, por algum motivo, sou eu que tenho
que lidar com eles o tempo todo.
