Ledo (our hero) is trying to communicate with Earth locals. With Chamber’s help (the AI voice) as translator, he starts his first conversation with Amy, the girl he kidnapped earlier. The initial “phase” of talk by eating some kind of dried fish is really funny.
So the Earth really turned into ice planet long ago, but the ice melted and it became sea planet (all surface is now water). Somehow mankind survived and now living on boats. With little technology they have, they bring old ships from the bottom of the sea back to the surface. For energy, they rely on a “galaxy current”, a natural phenomena where they have lightning strikes water, and energy is stored in lightbugs. Humans travel in group, connecting multiple ships into one big chunk. There are many colonies, including the bad guy: pirates. Amy’s colony is called “Gargantia”.
Naturally the next scene is about those pirates attacking Gargantia. By Amy’s request, Ledo and Chamber help them to eliminate the entire fleet of pirates.
