Azazel differs from the rest of the cast by being an angel. Azazel is shown to be curious, embodying the "Bright-Eyed Cadet" trope, venturing down into hell by herself to collect information on Demons. She's shown to typically be writing down notes, and is determined to do so, as in the epilogue, although seeming traumatized by her experiences in the demon harem, she still continues to take notes.
