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.
And I believe everyone 
deserves to be saved.
وأؤمن أنّ الجميع يستحقّون الإنقاذ
Ich glaube fest daran, dass es niemanden gibt,
der es nicht wert wäre, gerettet zu werden.
Para mí, no hay nadie
que no sea digno de salvar.
Para mí, no hay nadie
que no sea digno de salvar.
Je suis persuadé que tout le monde
mérite une seconde chance.
Sono convinto che non esista persona
 che non meriti di essere salvata.
E, para mim, todo mundo é digno de ser salvo.
И нет такого человека,
который не заслуживает спасения.
