From Assassin to Princess

She doesn't have a name but she's well-known. They call her a reaper as she can take hundred of souls in just a minute. She's feared. Everything about her is literally breathtaking. But everything changed when she was betrayed by her only friend who sold her out to those people who've been hunting her down. They succeeded but they mess with the wrong person, and this so-called reaper took their souls with her to hell. But then again, Satan is on her side, so he revived her in another world where wedding is another term for human trafficking.
