Bio/History: Twin offspring of an angel, mother, and demon, father. Kyle took after more of his father's demonic side. Aiden took after his mother's angelic side.

Kyle has a calculating, devious nature. Despite it, he usually doesn't worry about a lot. There are times his darker nature will take over. Usually though, when this happens, his more angelic brother will step in to bring Kyle back.

As for Aiden, he is a calm and serious individual. He prefers the silence, being the more professional of the two. Aiden is the only one who can calm Kyle down when he's in his demonic form and nature.

Despite their demonic and angelic differences, Kyle and Aiden actually work well together. The brothers have made their home in a large city, opening up a decently sized bar; The Serene Underworld.
