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.
If the hatred has no bounds, 
then I can do anything.
،إذا لم تكن هنالك حدود للكراهيّة
فيمكنني فعل أيّ شيء
Ohne eine Grenze des Hasses
vollbringe ich alles.
Si tu odio es ilimitado,
puedes hacer lo que sea.
Si tu odio es ilimitado,
puedes hacer lo que sea.
Avec une haine sans limites,
je peux tout faire.
Se il proprio odio è senza fondo,
si può riuscire a fare qualunque cosa.
Já que o ódio não tem limites,
eu posso fazer qualquer coisa.
Там, где ненависти нет предела,
я способен на всё.
