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.
So... there are two of you, right?
أي... يوجد اثنان منك؟
Ähm … Es gibt also zwei von dir, ja?
Este… dice que hay dos de usted, ¿no?
Eh… dices que sois dos, ¿no?
Donc, vous êtes deux, c’est ça ?
Ehm... Quindi ci sono due suoi  "io", giusto?
Então há duas existências, não é mesmo?
С собой?.. Так вас две?
