Shax

An original character called Shax. She's a demon and has been working as a waitress for the past year in a small town. Her original plan was to convert them all into part of her demonic army but then she found her humanity somewhere along the line.

After another of her fellow Dukes of Hell noted how much she cared for the people, he slaughtered them leading Shax to team up with an angel and a human guardian to help bring back the angel species to take down Satan or something.
