Erika and Sakaki manage to escape from under Sensei with her mother's guidance. Apparently, she's been making preparations, little by little, for Erika to run away one day. Erika learns of thoughts and feelings she didn't know her mother had.
After making contact with Mikado and the others, Erika tells them that she wants Sensei to stop doing the work they do, not just herself. Mikado decides to help, but it seems that Hiyakawa can't understand Erika and Mikado's feelings.
This was my house!
كان هذا منزلي
Das hier war einst mein Haus!
Esta solía ser mi casa.
Esta solía ser mi casa.
C’était ma maison, autrefois.
Je l’ai détruite.
Questa era casa mia!
Essa era minha casa!
Здесь мой дом.
