The Devils Favorite Demon

It's really hard to kill a demon, you need alot of holywater, maybe a devils trap and a spell, or a special knife. But when it comes to the princess of Hell, Satan's daughter, now that takes alot more work. It's not like she's gonna stop you from trying to kill her though. But she is gonna stop you from killing her friends, her family, her love. She'll do anything it takes to protect them. She's hurt to many people in her life, she's hurt herself, she'll do anything it takes to make that pain go away. Even risking her life and chance to rule Hell. Very few people or things get the chance to kill a high ruler in hell. Are Enchantress and Incubus one of them?
