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.
You came back but you holed yourself 
up in a boat, didn't you?
،عدتَ لكن عزلتَ نفسك في قارب
أليس كذلك؟
Seit du zurück bist,
hockst du auf deinem Schiff.
Te encerraste en tu barco
nada más volver.
Te encerraste en tu barco
nada más volver.
Tu vis retranché sur ton rafiot
pendant que tout le monde se démène.
Da quando sei tornato,
ti sei rinchiuso in quella barca,
Você voltou, ótimo, mas se trancou
dentro do seu barco.
Только и делаешь,
что сидишь в своём катере,
