It has been five years since you graduated from high school. During that time, you were restricted by your younger sister, but your freedom came when you escaped and tragically passed away after being struck by a truck. However, you were mistaken; your sister has been reborn in the same world as you at the same time. This time, you will break free of her grasp and live your life in a new world with the power bestowed upon you by God.
