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.

you aren't my destiny...

No lo entiendo…
Tal vez no eras mi destino…
No lo entiendo…
Tal vez no eras mi destino…
Je ne comprends pas…
Non capisco...
Eu não entendo. Talvez você não seja o meu destino.
Не понимаю...
Неужели ты вовсе не моя судьба?
