I'm not often caught on the above question but I suppose the tiredness I have here probably helps.  I had a stray idea (that I may or may not be RPING with someone as well) but I just can't make up my mind. Probably won't write it shortly but who knows. May end up as a short one shot lol

So... can anyone recommend me ships  (ANY) for this plot?

The heir of the 'devil' (or heir of evil, whatever) has reached the age where they are old enough to take up the role of the leader - but they need to kill a human (preferable young) to show their dedication. So there's a bunch of yaknow, explanatory mumbo jumbo there.

The human chosen is a youno orphan - no one would miss her

But she has a guardian angel that is there to try and protect her. 

The 'love' wouls be between the angel and the devil so yea. Any ideas? Pretty sure thus has been done before but I personally hadnt read anything like it

Just..everything has been written a few times already X
