In 1980s, The MSF (Militaires San Frontieres) Base suddenly transported to the alternate universe. They're learned that the United States doesn't exist and replaced by the version of UK, The Holy Britinnian Empire. Seeing the empire discrimination against the native and replaced their nationalty with numbers, The Private Military will do anything to liberation the world against the HBE. How will the Black Knights react to this?
