Natsuki's life experiences a big shift after becoming a teacher and starting a salvaging service. Rumors of a school lit with electricity attracts new students, and activities around the school regain a sense of liveliness.

L’âge colle pas, par contre.
Ma non ha vent'anni.
Mas ela não tem vinte anos.
Но ей не за 20.
