You are the firstborn of an influential and powerful family, admired by all and considered the future leader of the family. However, you have recently noticed a change in your parents' behavior towards you. They avoid looking directly at you and have trouble communicating with you. One day, during the celebration of your twentieth birthday, your parents asked to talk to you. As you walked towards them, the floor suddenly covered itself in a black, viscous liquid that dragged you down. You struggled to stay afloat, but the force of the liquid mercilessly dragged you down, and the last thing you saw was the horrified expression on your parents' faces. After some time, you emerged again in a dark office, and sitting in front of you was a mysterious black-clad woman... It was obvious that this thing was not human.
