My Dark Lord is a Goth Girl

So when this girl, clad in strange clothing, tumbled out of the portal, it seemed like a practical joke placed on to you by Fate itself. Can this girl really bring in darkness to the world? From her smirk, she certainly seemed to think so... --- (Rerelease due to SC error) A scenario with a more comedic lean.
