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.
When I encountered it, it was like destiny.
عندما التقيتُه، كان أشبه بالقدر
Die Begegnung damit war schicksalhaft.
Encontrarlo fue obra del destino.
Encontrarlo fue cosa del destino.
Le destin voulait
que je tombe dessus.
Trovarlo sul mio cammino è stato
 come un segno del destino.
Quando eu encontrei, senti que era o meu destino.
Это и впрямь было похоже
на подарок судьбы.
