I thought another nuclear bomb had dropped that day. But suddenly the sky opened up—a white, smooth, shiny saucer descended, and from within it, white, shiny, lanky bastards poured down in droves.

"Thank you, everyone." "We've been waiting for the chance to take this for ourselves someday, and to think you'd self-destruct like this!"

Those were their first words.

The government, faced with the sudden alien(?) intrusion, exhausted what little was left of the national treasury to mobilize all weapons and pour them at them, but it was useless. Instead, an unprecedented situation occurred where we were the ones getting slaughtered.

Eventually, feeling the insurmountable difference in power, the US government raised the white flag. Even though the whole Earth was ruined by war, after the defeat of the US—once the world's strongest superpower—China, the UK, Russia, and Korea followed suit one by one, and eventually, Earth became a colony of the aliens.

Five years have passed since then.
