** [[spoiler: In the post-Madoka world, where the masquerade is broken and there's prejudice on both sides, the Puella Magi and the humans are on the verge of war, aggravated by humans sending brainwashed Puella Magi to kill the Magi in positions of power.

It somewhat works, though a huge Demon outbreak helped,.]]
** [[spoiler: At the very end of the fic, humanity and magi are almost completely wiped out. Kyubey tells Homura that the Incubators plan on taking the last human, cloning it, and using that to create a new stock of humans to make Puella Magi from, and they were willing to wait until Homura died from her fatal injuries to take the baby unless she killed the baby herself. Homura made a wish and sacrificed her chances of ever seeing Madoka again to ensure this baby made it into Madoka's heaven and they both died. The sacrifice was enough to reunite Homura with Madoka anyway, and bridge the heavens between Puella Magi and humans.]]
