Anxiety itself is a demon which is currently possessed by two souls. Both are human souls, neither named. One soul is a calm, thoughtful individual who realized their situation, being stuck as a demon. He is not violent, and tries to avoid taking any harm. However, he does not know how to fight back against people trying to kill him. They long for the vessel of Anxiety to be their own. The other is not as peaceful. In fact, they are very violent.
