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.
I... want to stop that from 
happening. No matter what.
أريد... منع حصول ذلك، مهما تطلّب الأمر
Das möchte ich auf jeden Fall aufhalten.
Yo… quiero parar eso, a como dé lugar.
Yo… quiero parar eso, sea como sea.
Je veux mettre un terme à tout ça.
Io...
Eu quero impedir que isso aconteça.
Custe o que custar.
Я не дам этому продолжаться.
