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. 
Natsuki can't swim after all.
فناتسكي لا يُجيد السّباحة
Er hat doch keine Chance
gegen mich …
Natsuki no puede nadar.
Natsuki no puede nadar.
N’oublie pas
qu’il ne sait pas nager.
Anche perché il signor Natsuki non sa nuotare.
Он ведь не умеет плавать.
