In another world...

Magical kingdoms reign across the lands. Serfdom, corruption, slavery, and wars persist throughout history. Two tall continents are parallel to each other. From grasslands to splendid castles, the kingdoms forged alliances and enemies with one another. There's no such thing as "a war to end all wars." A tiny quarrel on a farm could spark a global war again. The leaders midst of these conflicts has thought, "Something will be done by God to stop this all."

And that's what the tales say.

On Earth, the United States vanished-and appeared in the world of magical kingdoms. How will the lives of the very people in this new world react to this phenomena?
