You were just about to attack the gang, however that's once you feel a another cluster of souls come closer to the gangs location.
Then you see them with your own eyes. About twenty people each one wearing a insignia somewhere in their clothes appear. The group of twenty all suddenly brandish a knife or some other sort of weapon and begin charging at the original gang.
Your not sure what's happening as a full blown gang war starts. People were punching, stabbing, and breaking each other.
You on the other hand are quite surprised. You knew that this part of the city had gangs, but you didn't think they participated in battles. Wanting to get a better view you, in your invisibility climb up on top of the connivence store and watch the battle unfold.
You weren't quite sure who was winning now, the two gangs seemed to be equally matched as they fought. Perhaps you should make things more interesting. You open your muzzle impossibly wide and watch as thousands of shadowy tendrils, made up of pure darkness erupt from your mouth.
The tendrils suddenly all lunge forward like the tentacles of a giant octopus as they begin attacking the gang members below. The tendrils easily pierced through their clothes and body's, making wounds more fatal than a gunshot.
Both gangs began panicking as the shadowy tendrils came upon them, ripping their clothes and bodies apart as blood and gore starts covering the ground.
However summoning the tendrils had a negative effect on you. Due to your inexperience in magic you had to give up the effect of your invisibility, making you visible.
One of the gang members who still hadn't been killed by your tendrils notices you and that your the source of the tendrils, to his credit instead of running away, he comes closer to you and throws a wicked looking dagger which pierces your right arm due to you not realizing your no longer invisible allowing him to hit, purple blood starting to flow from the wound.
You would've scream were it not for the massive amount of tendrils coming from your mouth. You use your left arm and pull out the dagger, your cry of pain muffled as the blade is pulled out from your arm. Then you cover the blade in a dark hellfire and throw it back to the person who harmed you. The man died instantly as the flaming dagger pierced his chest, his entire body igniting in black flames.
By now only aa couple of gang members remained and were quickly taken cared of by your shadow tendrils. As your dark tentacles killed the gang members they also extracted the souls from the dead bodies for you, licking your lips as the tendrils literally fed you the souls. Delicious.
After making sure there were no survivors you open a giant gate to the abyss and watch as all of the dead corpses fall into the underworld, most likely to be used as undead servants for what ever demon lived down there.
You gave a big burp as you consumed all of the souls. Thankfully your wound was starting to heal quite quickly as you snapped your fingers and returned to your human form. All those souls you just ate would fill you up for a while. Maybe you'll use that time to chill at your apartment, you could use a break.
After arriving at your luxurious apartment you begin to chill. You sit on custom furniture designed for your demon fox form as you watch movies and play a couple of video games on several consoles that you bought using all the money you created.
This sure was the life, eating souls was fun and all but sometimes you just need to sit on a couch and relax. After all, you did just destroy two gangs in the slum.
