Oceans of the Strike Witch world Edit
The oceans of the world appear to be differentiated slightly more than our normal Earth. For instance, it does not appear to be the Pacific Ocean or the Atlantic Ocean. Literally translating the locations on the published world map for Strike Witches shows that there is the North Pacific Ocean / South Pacific Ocean and the North Atlantic Ocean / South Atlantic Ocean.
This could stem from being an oddity in their map or considered the norm for their world. The Indian Ocean remained the same, while there is a North Arctic Sea and a South Arctic Sea (instead of the Arctic Ocean and the South Ocean.)
