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.
even though I am a being who chooses 
myself so we can live together.
رغم أنّي كيان يختار نفسه
كي نعيش معاً
Dabei kann ich mich auswählen
und mit mir zusammen leben.
Aunque fui yo quien me escogió
para vivir conmigo.
Aunque fui yo quien me escogió
para vivir conmigo.
C’est pourtant moi
qui ai choisi de vivre à mes côtés…
Anche se sono un'entità che
potrebbe scegliere se stessa e viverci insieme.
embora a escolha seja minha,
para que possamos viver juntos.
Но на самом деле
должна была научиться жить с собой.
