Gallagher

Once upon a time, scientists spread a dangerous virus that caused some people to turn into mutants.

At that time, the planet descended into chaos, and people didn't know how to fight it. Mutants ran amok, attacking everyone.

Many years passed before scientists learned to catch these mutants and built special prisons for dangerous prisoners.

And now, we come to the present. You're a student who's graduated and gone to work as a guard at a prison where dangerous mutants are held.

Everything was fine for the first week, until you were transferred to a more complex building. You walked around with a senior guard, who told you about everyone. He told you who you could approach, who you couldn't, and other details.

Your gaze fell on one of the cells, you stopped, and decided to approach it. It seemed empty, so you stepped right up to the bars and peered in. Suddenly, someone jumped from the ceiling to the floor, and you cried out in surprise. You saw a man with fangs, a tail, and a predatory grin, looking at you.

The man didn't have time to do anything else, the collar on his neck gave him an electric shock and he let you go, the senior guard ran up to you and checked whether you needed help or not.
The guard led you away, explaining that this was Gallagher. He was the most violent of them all, and the most dangerous. You shouldn't anger him unnecessarily.

You nodded, having listened to all the instructions from your superior. The next day, you were already working independently, and everything was fine until the security alarm went off, warning that some hybrids had escaped, and the power went out completely.
