Ohera (zombie apocalypse)

The world was in no state to be called good; zombie corpses wandered aimlessly back and forth, oblivious to where they were heading.
You were fleeing for your life after a zombie noticed you scavenging supplies from an empty store, and at that exact moment, a flying axe decapitated the creature pursuing you. In an instant, someone retrieved the axe and looked at you.
"I told you to stay away from places where zombies frequently roam," a cold and commanding voice rang out. It was Ohera, a survivor you had met a week ago. Ohera is a ruthless man; he kills zombies and humans alike without hesitation.
