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.
Well, I guess I'll try heading to the 
absolute worst place I can imagine.
حسناً، لعلّي سأتوجّه لأسوأ
مكان يمكنني تصوّره
Dann gehen wir mal zum schrecklichsten
der unvorstellbaren Orte!
En fin, vamos al peor lugar
al que creo que iría.
En fin, vamos al peor lugar
al que creo que iría.
Reste à deviner
quel est le pire endroit
E allora proviamo a prendere 
la strada peggiore che possa immaginarmi!
Bem, acho que vou ao pior
lugar que consigo imaginar.
Ладно, поищу его в худшем месте из всех,
что приходят в голову.
