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.
Well, I mean, if you just keep 
holding on to bad feelings...
...إذا واصلتَ التمسّك بالمشاعر السيّئة
Du kannst doch nicht ewig
mit diesem schlimmen Gefühl leben!
Es que siempre te guardas
esas emociones negativas.
Es que siempre te guardas
esas emociones negativas.
Si tu t’enveloppes
de toutes ces émotions négatives…
Voglio dire...
Bem, se você ficar se agarrando
a sentimentos ruins...
Конечно!
Ты хочешь вечно утопать в негативе?
