Zombies vs Her-I mean villains...

Once upon a time there were two siblings. They went through hardships unbefitting of innocent children. And yet, they did not break down. Their willpower to keep standing despite the whirlwind of misfortune changed something within them.

And along with that change came their supernatural abilities. And what better way to use those abilities to get back at the society who was responsible for their misfortune?! - or so was the aspiration of Aaron's brother.

Personally, he couldn't care less about such a thing as long as he's getting paid enough that he can live a comfortable life. So after being promised a good salary he joined his brother to run this so called evil organization...only for something to foil their plans before they could even start their activities!

A zombie outbreak emerged in the country they lived in, causing the entire population to fall into despair. The despair their evil organization should have been the one to be dishing out!

"So uh what do we do now? Just ignore the outbreak and terrorize the citizens in our own way?"

"No, you fool! We can't terrorize the citizens if they're all brainless undead! We have to exterminate all the zombies!"

...and so began Aaron and his brother's quest to save humanity from the undead...only so they can terrorize them themselves...?
