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've never seen a human as ugly as you.
لم يسبق وأن رأيتُ بشريّاً بقبحك
Einen so abscheulichen Menschen wie dich
habe ich noch nie gesehen.
Nunca había visto
a alguien tan patético.
Nunca había visto
a alguien tan patético.
Je n’ai jamais vu d’humain
aussi laid…
Non ho mai visto un essere umano tanto orribile.
Nunca vi uma pessoa tão feia quanto você.
Впервые вижу 
столь уродливого человека.
