System in Release that witch! [AU]

Fan-fic based on Release That Witch.
A little warning: I am writing this only out of boredom so don't expect consistent updates. My English also isn't top-notch.
Don't expect big plot changes, as I said before, I am just writing this out of boredom. This is also AU so there might be changes completely out of the original plot (for example new witches from other series etc.)

You have been warned, now it's up to you whether you want to give it a try or not.
