How to watch One Piece
One Piece is a pirate based anime where all the world is covered in waters, with the only practical habitable land being islands. The only continent, the red line, reaches the height of clouds and thus is practically inhabitable. The red line crosses across the world and divides it into 2 sections, while the grand line does the same and crosses through the world and the red line. This creates the 4 blues: the north blue, the east blue, the west blue, and the south blue.
The Grandline is a giant sea that crosses around the world, full of evil weather and dangers alike. It is surrounded by 2 calm belts, which are completely calm with no wind and no current, and home to the sea kings or "sea monsters" thus not traversable.
