I'mma go for a bookworm. Originally hired to the force to help with paperwork and tidy the books in a metaphorical and literal sense. Alter ego is Wraith (placename for the moment), a ghost/spirit style magical girl.
More creepy-cute than anything remotely sinister though. Probably Witch...
Hookay. I'll have the concept up soon. Statting may potentially have to wait till possibly late Monday if that's at all okay, as we're heading home tomorrow morning and there's that great big bloody pond in the way of internet connection.
