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 was nothing more than a sad, 
lonely fighting machine.
لم أكن أكثر من مجرّد آلة
مُقاتلة وحيدة وحزينة
Und war zu einer einsamen und
bemitleidenswerten Kampfmaschine geworden.
Me volví una máquina
de guerra solitaria.
Me volví una máquina
de guerra solitaria.
Seule et abandonnée de tous,
Sono rimasta tutta sola.
Me tornei apenas uma máquina
de combate triste e solitária,
я, безутешная машина уничтожения,
осталась одна-одинёшенька.
