Natsuki accompanies Atri who is on her way to school. However, when they arrive, they find that most of the school is underwater. Although they managed to get into the school building, inside it was full of empty classrooms and an unexpected teacher. There, Natsuki is faced with the saddening reality of the lives of the people who remained in their town.
I'm just a little jealous that you've 
trusted and used that thing
أغار قليلاً فقط لأنّك وثقت
بذلك الشّيء واستخدمته
Aber dass du so einem kaputten
Klappergestell mehr vertraust als mir,
Ça me rend juste jalouse
de te voir t’accrocher
Pensavo che ti affidi a questa protesi
anche se è ridotta male,
Eu só fiquei com um pouco de inveja de
você ter confiado nisso e usado tanto...
Просто я немножко завидую протезу.
