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.
But right now, that feeling 
might be what I need to stop.
لكن الآن، قد يكون ذلك الشعور
هو ما عليّ إيقافه
Aber ich muss ich vielleicht einschreiten.
Deswegen möchte ich wissen.
Pero ahora quizás deba impedir
que lo haga, por eso quiero saber.
Pero ahora quizás deba impedir
que lo haga, por eso quiero saberlo.
Je dois à tout prix
faire quelque chose contre ça.
Però credo di doverlo fermare, adesso.
Mas talvez seja esse sentimento
que eu tenha que impedir.
Кажется, я должен остановить
такого человека. Поэтому хотел бы понять.
