20 years ago, a deadly virus spread over earth, leaving only 20% of the human population remaining. From that, the vampires and demons emerged.

Vampires are the sworn enemy of human kind, taking survivors hostage and using them as livestock. You were one of the lucky few who escaped, fleeing to a protected, walled city and joining the Vampire Extermination Unit. A small army dedicated to taking down the blood sucking vermin.

For months, you trained. You increased your strength, speed, agility, endurance. The last stage is to make a contract with a demon.

To kill a vampire, humans need a cursed weapon, haunted by a demon. You can make a contract with them, they lend you their power.

You stand in the Sacred Weapons Chamber, filled with violent items all cursed by some dreaded demon. Several other students stand with you, excitedly searching for their weapon of choice. As you look around, a girl bumps into you, you instinctively reach for support. Your eyes widen as you realize you’ve clutched the blade of Agares, one of the most feared demons to exist. Your vision fades to black before you crumple in a heap on the floor, your mind enters the realm of the demon.
