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.
I just happened to be passing by. 
There's no need to thank me.
صادفَ وأن مررتُ من هنا. لا حاجة لشكري
Passavo di qui per caso.
Non c'è bisogno di ringraziarmi.
Eu só estava passando por coincidência. 
Não precisa agradecer.
