Dissonance, Innocence, Arrogance

In a world of utter chaos, the population of mankind is 2%, other inhabitants following are the androids, robots with intelligence of their own 15% of population. Next are the dead or rather undead, more accurately known as zombies, whom define a population percentage of 21%. Leaving the mutants to dominate the remaining percent of 62%, formerly human, having undergone an experiment in the name if a cure...those that didn't become part of the undead or became puppet bodies for the androids to fiddle with, the individuals whose DNA merged accordingly with the DNA of that was injected into them...their bodies became changed in ways that border horrific and even hellish. All species in an all out war for survival, humans fight with guns, grenades, modern to advanced warfare. The undead animate their corpses to seek out warm flesh, organs, ligaments, and brains to sate an insatiable appetite. Androids easily construct weapons of mass destruction to decimate anything and everything in their paths. Mutants have a fighting style unique and befitting of them, taking advantage if their mutated bodies, they've developed their own way to survive. A mutant and human become trusted comrades in arms, gaining allies, eradicating enemies, in this twisted world, no one's sanity is ever truly sane, some even broken, some outright insane...will they find a survive? And if so, how can two beings of opposite origins find love? (Three shot featuring Nafuka in all three pairings with the other character seen in each chapter pic)
