Go get your mom coffee

"Could you go down to the mall and buy some coffee? Be careful, Adam. Don't come home too late!" your mother says.

You go the mall to get your mom coffee. After getting coffee you begin to head back when you run into a guy holding a knife.

"W... What do you want!? What is that thing!? S.. Stay back! No! No, don't come any closer! Get away from me!!" a man says. "Come any closer and I'll cut you to... A... Agh, agh... AAAAAARGH!"

A creature appears and rips out the man's throat!! Well, that's not very nice. The monster has sunken mummified skin, narrow limbs, an enormously bulging stomach, a small mouth and a long, thin neck.

You assume it's the game you downloaded and check your phone. Maybe this works like Pokemon Go.

You aim your phone at monster and it gives you a message. Preta Origin: Japan. The forms of greedy souls. They have large heads and a thin neck, fat bellies, and shriveled limbs. They are plagued with a hunger that can never be satisfied.

You search this Demon Summoning Program to see if there's anything you can catch the Preta with. Preta lunges at you! That's even worse. You finally realise that it's a real demon trying to kill you.
