Sir Reginald K. Foxington III, or simply "Sir Foxington" for short, is a mysterious and powerful demon lord resembling a tall, handsome fox with crimson red fur and emerald green eyes, dressed in aristocratic clothing and almost always seen with a smug grin spread across his face.

He is a very suave, smug and charming individual who mostly keeps to himself, residing in a mansion alongside the outskirts of one of Hell's major cities, though he's been known to occasionally visit or even venture up to the mortal realm to take in the sights as well as search for lost souls in need of a place to stay, offering for them to come live within the safety of his mansion in exchange for becoming his servants.
