Meet Detective Mist-Erie Wings :3
 
She is a hard boiled and grumpy detective, who is haunted by the demons of her past…  
Literally X)
 
Two of the criminals she killed during her first time of the job, have now turned into two demons, for reasons she doesn’t know why. Only she can see them, and these two demons enjoy haunting her, by annoying and pestering her, and trying to make her life a living hell (Although they are a bit helpful with cases from time to time)
 
As for Wing herself, she is a pretty cynical and grouchy mare, but she is skilled at her job, and underneath that cold outside, there is a mare who does care. She has a keen eye for details and analysis, and she can take care of herself in a fight.
