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.
My stuff won't fix itself if 
you break it with your hammer!
Mein Zeug repariert sich nicht von selbst,
 wenn du es mit deinem Hammer zerschlägst!
¡Mis cosas no se reparan cuando 
las rompes con tu martillo!
¡Mis cosas no se arreglan 
rompiéndolas con tu martillo!
Tout ce que tu casses avec ton marteau
ne se répare pas automatiquement !
Quando você quebra com seu martelo,
minhas coisas não se consertam!
