Harry Potter and the Suburbian Satanists

What happens when a family of hobby satanists from suburbia adopts Harry Potter? Guaranteed to be dark, twisted and filled with humour and a few Eldrich monsters. Devils, demons and the Antichrist features inn as well. May or may not end up as a crackfick. Dark humour and insanity. Crossover with the Suburban Satanists. Dark harry. Evil Harry.
