Sera is one of Heaven's top-ranked Angels, and leads the Seraphim order, which was named after her. She is a tall curvaceous beauty, with a gentle and motherly attitude. She dislikes uncouth behavior, particularly scorning the actions of the fratboyish Adam the First Man. However, she still allows him and his Exorcist angels to perpetrate annual Exterminations in Hell, all in the name of protecting Heaven and her fellow Angels. To that end, Sera will go as far is needed.
