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.
I can't believe you're swinging 
that thing around here, again.
Ich kann nicht fassen, dass du schon wieder dieses Ding hier umherschwingst.
No puedo creer que uses 
esa cosa aquí de nuevo.
Me parece increíble que 
uses esa cosa aquí otra vez.
Comment oses-tu brandir 
ton marteau en ces lieux ?
Não acredito que você ainda está
brandando essa coisa por aqui.
