Why did I name my OC Reaper

So, I decided to explain why did I call my OC such strange name - Reaper. Yes, that name sounds a bit spooky, and this is not normal name for girl of course.
For a long time I could not choose her name and so I used my own, but her appearence didn't match her/my  name, no matter how strange it sounded. I had no idea at all, so I decided to find the word  which could show some of her features.At  the beggining she used a  big metal scythe as weapon, and her story(which too long to describe here) was full of bloody revange.  Also I mentioned about  ghosts in her reference, these were victims of murderes(murderes are  some of Reaper's " "good" acquaintances", whom she avenged.).
At the end, her metal scythe became a  clot of energy, which reminded the form of scythe, ghosts  turned into voices and visions, revenge remaind the same. The word, that could describe her hunt for murderers lifes, and her attempts to free the restless souls, was "reaper", wich became a nickname, and than a constant name.

I am sorry for mistakes.
