"GROWL..."

"GET LOST!!!"

Rage surged through a seventeen years old boy as he lunged forward, slashing his sword at the unnatural being that had leapt towards him. Despite their human-like appearance, these beings were no longer the humans they once were.

What set them apart were their fiery red eyes, small blackened veins coursing over their bodies, and, most terrifying of all, their insatiable, bloodthirsty nature. They were what movies or novels called 'Zombies'.

"Growl!" A guttural growl resonated as a Zombie launched itself towards him, its bloodied mouth gaping wide open. But with a swift movement, the boy's sword met its neck, severing it before the creature could come near him.

"Ha..." Despite his body being exhausted, there was no time to rest, as more of these relentless Zombies surged in his direction. 

"Why... Why... Why..." He mumbled as his voice was filled with helplessness and despair.

It wasn't the sudden danger or the bloodthirsty creatures that weighed on his heart, but the presence of an unconscious girl bound behind him.

Her body was burning hot but what truly made him dreadful was a huge bite mark that was visible on her white neck, from where black pus was oozing out. 

His emotions were running amok because of the situation she was in and he was unable to provide the help she desperately needed. 

"I am never going to leave you behind... no matter what..."

It was all normal for all of them when suddenly a game-like interface popped in front of them and it was then that all hell broke loose. 

It was the day that humanity became the prey.
