Anthea is a succubus who usually humors Felix whenever he is distraught. He comes to her first, knowing she is somewhat of a pushover and can’t refuse him. She has an affectionate fondness for Felix and does not want him to come into trouble, which usually results in her being dragged along in one of his schemes. Anthea is actually a nice person, the only reason being that she defected from Heaven was to watch out for Felix. Before she left Heaven, she and the Archangel Gabriel had acknowledged they both possessed romantic feelings for each other.

She is an escort, is technically younger than Felix, and wishes she had more female friends.
