Well, realistically what's the worst that can happen? Your a demon! You can do anything. If worse comes to worse you can easily turn invisible and run away.
You were wasting daylight out here. Just go into the prison and eat as many souls as you can then get out.
Snapping your fingers you turn invisible and run towards Winterslam, the smell of evil and darkness making your mouth drool slightly as you easily jump the metal fence and enter the first "layer" so to speak of the prison.
Being invisible none of the partoling guards or snipers saw you as you moved around. None of them expecting a demon fox to be one of the things they had to look out for, much less be trained to deal with one.
You jump over the second outer fence and soon make it inside the inner part of the prison. You move towards the concrete wall, and with your bare fist, you punch straight through it, smashing the wall into a large hole for you to go through and making a sound that was like a train crashing through a building.
Alarms go off immediately. Red sirens go off and the guards that were patrolling immediately start running towards the source of the noise. Grinning a toothy fox grin, you go through the hole and see a tasty sight. You were in a courtyard filled with what seemed to be hundreds of prisoners. Each one wearing a organe jumpsuit that told people of the crimes they committed. You inhale deeply and start feasting. Making sure to make every morsel last.
You begin the tasty process of savagely ripping into every prisoner near your eating their souls and drinking their previous lifeblood as you tore into them. Ripping out their chests in a gory mess as you go on a uncontrollable rampage.
Each prisoner you maul quickly turns into a bestial black fox man, their clothes bursting, all of them snarling, each of them in a primal rage like the one your in now. They seem to ignore the prisoners and head directly for the guards.
Soon a all out battle between prison guards and demon foxes began as each person you kill gives you a tasty meal and another loyal soldier.
After a few minutes, the prison has gone into complete lockdown. Alarms were ringing loudly, and lights flashed in the afternoon sun as guards hurried to battle the powerful beast men.
A small portion of your mind that wasn't in a bestial rage did feel remorse for killing all these guards. After all they were just doing their job. But you figured that atleast you weren't sending them to the underworld.
You keep raging on, losing count of how many prisoners you killed and turned as you start making your way inside the prison itself. Your docs are right behind you, howling with joy as they follow their alpha.
