(SAMPLE) In a post-war world, humanity finally knew peace—until the heavens turned hostile. After surviving a surprise invasion from the underworld, the world believed the worst was over. But the true threat came from above. Without warning, angels descended—not as saviors, but as exterminators. Their wrath spared no one—not even the demons below. Within just a few years, both Earth and Hell were laid to ruin. Now, in the wreckage of two fallen realms, hope rests on an unlikely alliance: a demon and a human. Separate lives. Separate stories. Soon to become one. Together, they will rise—a single force to reclaim their shattered worlds.
