Black Butler X Reader

YOU are a young lady who lives on her own and runs her Father's Tea Industry. Your mother died when you were at a young age and your father is now locked away in prison for first degree murder. Much like a few other Nobles you work for the Queen when comes to jobs that need to be kept below the radar. So below that not even the Queen's Watch Dog or Spider know of your recent activities. You are know as the Queen's Kitten. While you do work alone you do sometimes copoerate with others on certain tasks while at the same time wish they would drop dead. So needlessly to say you aren't little miss sunshine. Exspecially since your fiance died less than a year ago. Now you are a deadly, overprotective, anti social hitwoman for the Queen. And none of that changes even a blue haired Noble and his Butler from Hell are required to work with you on a case so dangerous that someone may consider falling back.
