A demon soul resembles a search black flame shadow person when it possesses a human. The black Flames are very deadly to Angels.
A Angel so resembles a blue and white soapy bubble person. The song is basically like Glue and could you very deadly.
In conflicted sins a human can be possessed by a escaped soul, it doesn’t matter if the soul is from heaven or hell if a human is possessed, they can no longer go back to being a normal human (unless the hybrid is the one to remove the soul, if god were the one to remove the soul the human will most likely become an angel. If Satan were the one to remove the soul the human will most likely become a demon) if a normal angel demon or a lower-ranking angel demon where to remove the soul, the human will no longer exist because there they’re humanity and current soul is already devoured by the Escape soul.
