A Devilish Adventure

You sell your soul to the devil, your wish: a friend, so in the 10 years you have left of your life the devil, or Luci as you come to call him, begrudgingly comes to care for you. So, when your time is up and it's time for your torture (As per usual). And Luci can't stand to see your pain, so he sets you up as one of his advisors. This is the story of how a meek, little woman with anxiety issues becomes the Second in Command to Satan himself, and gets to control all the little demons.
