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.
That harpoon and my grudge are 
the two things I never want to rust.
تلك الحربة وضغينتي هما الشّيئان
اللّذان لا أتمنّى أن يصدآ

que je ne veux pas voir rouiller.
Quell'arpione e il mio rancore 
non arrugginiranno mai.
Eu não quero que enferruje, 
nem isso e nem meu ódio.
Только они...
