Righting Their Wrongs (A Challenge Story)

*This is not a written Story, but a challenge fic.*
They had lost the war. No one had though that would happen. They had thought - known - there would be causalities - one both sides. It was unavoidable. But none of them though - not even for a second - thought that they would be defeated. Truly and utterly defeated...but it had happened. The heroes had lost to the villains and now all looked lost. But even so, those left standing refused to give up. They'd fight to their last breath if it came to it - which it just might. They refused to give up and lose hope, even if there was no true chances of them winning - they had to try anyone. That's what it meant to be a hero. Even so...they'd need a hail mary to turn things around at this point.
......a hail mary is just what they might get, if Monoma has anything to say about it.
