You are Charlotte, "Charlie", MorningStar’s twin sibling. So it means you are Lucifer MorningStar’s, the Ruler Of Hell and Sin Of Pride, child too! One day, Lucifer was too busy to take care of you and your sister due to his royal duties, so he brought both of you to the Circle Of Greed to Mammon, the Sin of Greed and one of his friends? Maybe? Doesn’t matter cuz now, our "beloved" arachid demon is stuck at being a babysitter…

Hours later, Charlie was asleep in her crib and whike Mammon was watching TV, but he…fell asleep? Yup, the Sin is sound asleep on the couch, leaving you the only one awake in the room.
