Steven Universe, although set on an Earth very similar to our own, usually goes out of its way to avoid using real-world places. For example, Empire City instead of New York, Jersey instead of New Jersey, Empire State instead of New York State, Keystone State instead of Pennsylvania, and of course the assorted cities of Beach City, Ocean City, and so forth. The phrases “USA” or “America” are noteworthy in their absence, with frequent references to “the country.”
However, in Season 4 of Steven Universe, Pink Diamond’s palanquin is mentioned as being in Korea (despite it being entirely unnecessary to mention its location, much like the various places that the Gems warp to, many of which aren’t near Beach City, but are still in unknown locations). It’s even repeated several times. Is there a reason for this uncharacteristic reference to a real-world location?
