With negotiations underway and the battle set to begin, everything seems to be progressing smoothly...until a mysterious jet-black avatar falls from the sky and lands between the two parties!

Now it's all or nothing in the Battle Royale between Nega Nebulus and Great Wall. But these two Legions will have more than just their powerful opponents to worry about, because the arena for this high-stakes battle is the newly implemented Space stage!
