Ever since her mother was lost in Antarctica, Shirase has felt like she was lost in a terrible dream. Despite her fear of what will happen if nothing changes after she goes, she and her friends now set off on their final journey to the place where her mother was lost.
Because none of us knows what's 
going to happen out there.
.لا يعرف أيّ أحد منّا ما سيحدث هناك
Man kann nie wissen, was passiert.
Nadie sabe qué podría pasar después.
Nadie sabe qué pasará después.
On ne sait pas
ce qui peut nous arriver.
Perché nessuno di noi può sapere
cosa succederà là fuori.
Afinal, não sabemos o que
pode acontecer conosco.
Мы не знаем, что нас ждёт нас впереди.
