Their name is Mel, they were about to be punished by heaven itself so they went to Earth undercover in human form. Uses a necklace to turn into human form. Turned into a fallen angel because they did a mission wrong and ended up badly, making heaven almost lost Mel's wings and Mel escaped barley to Earth. Mel carries meds to help with both pain and insanity...they maybe a side effect that doesnt effect health or mentally. The meds make Mel easy to hurt making vulnerable to be possessed by demons
