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 no longer possess 
anything precious to you.
لن تمتلك شيئاً غالياً عليك
hat man nichts mehr,
was einem wichtig sein könnte.
es porque ya no te queda
nada que valga la pena.
es porque ya no te queda
nada que valga la pena.

plus rien d’autre ne compte.
significa che ormai non si ha 
più nulla che si consideri importante.
não há mais nada que seja
precioso para você.
для тебя уже нет ничего драгоценного.
