On their way to Akita, Bisco and Milo pass by the sea of Calbero and arrive at a desolate town under threat from the deadly creatures, Flying Blowfish. A town that's also full of children and devoid of adults. Meanwhile, Pawoo encounters a mysterious couple living in some ruins as she pursues the others.
After everyone was gone, we moved here.
بعد رحيل الجميع، انتقلنا إلى هنا
Dann wurden es immer weniger Leute
und wir sind hierher umgezogen.
Quando se ne sono andati tutti,
ci siamo trasferiti qui.
Depois que todos se foram, 
nos mudamos pra cá.
