Home, 3:00 AM

Stress and adrenaline courses through veins as you walk through your home with your pistol in hand. Even the slightest sound makes you jump as your traverse your once safe home.

It was another one of those night, where another monster has followed the demonic energy radiating from your mark and are looking for you.

The mark, or by "The Mark of M" was forced on you by your friend to enemy after a heated argument. You can still feel the burning hot hands on your back as his demonic henchmen held you down. The strange language filling your ears as he spoke in a indecipherable language. Next thing you know, you felt the piercing pain of a symbol being cut in your wrist.

The mark has but one purpose: It puts a big target on your back.

It converts your soul into one of a vessel fit for consumption by demons. Your soul becomes a all-you-can-eat buffet for any demon that's around. All it takes a sniff or them to sense it off of your soul before they start looking for you.

As a result, every second of every day your life is in a constant state of slaying demons and surviving. There is barely any respite, even in your own home which you thought would be demon proof with the amount of wards you added.

SMASH!

Well...that's not true as you hear the sound of a portrait falling and breaking. You know living like this will eventually end you and that you need find your ex-friend asap if you want any chance to be free from this.

But first, you need to deal with your uninvited and perhaps bloodthirsty guest.
