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.
It will. Do you think that seems
 more fitting than "youkai"?
أجل، أتظنّ ذلك يبدو
ملائماً أكثر من "يوكاي"؟
Genau. Das ist präziser,
als es einen Yōkai zu nennen.
Sí, creo que es más acertado
que llamarlo espectro.
Sí, creo que es más acertado
que llamarlo espectro.
C’est ça. C’est sans doute plus juste
que de parler d’esprit.
Proprio così.
É. Parece mais adequado do que chamar de demônio.
Пожалуй, да.
Это гораздо ближе к правде, чем «призрак».
