It's the year 2040.
A normal day, bright sunny day in UAC(United American Continents).
However a two Roman like gates opened up in Bering Sea within the Diomede Islands and main street in Glenwood Park
Norfolk, VA.
And a Roman like army and navy came out of them and was about to attack, but were destroyed the second they came out by UAC Marines and by UAC & Russian Navy.
How will both JSDF and UAC react to each other?
Let's find out!
