Plot: After Zero resigns himself to death after defeating Weil aboard Ragnarok, a freak energy burst from Weil knocks him out. When he comes to, he finds himself back in the past when Ceil awoke him from his sleep.
I see...well the original idea was that the energy wave not only sent him back in time but Weil as well, but if Zero is sent back in time before the Maverick Uprise...yes...yes I like where this is going.
