Artemis Black (Fem!Harry), Master of Death and war-hero, wondered why the Potter luck was still in play even after she had magically changed her name. For Merlin's sake!

And how in Morgana's name did she get mistaken for the actual Greek Goddess of the hunt?
Sirius Orion Black was the only person who mattered to Carina Artemis Potter-Black (fem!Harry). He was the apple of her eye. The man she called, "daddy". And if he were to ever die...she would let the madness that simmered under her skin consume her...and raze magical Britain to the ground.
Self-Insert! An assassin from the real world dies and merges with another version of herself in a completely different universe. Katekyo Hitman Reborn. It turns out that the "her" in this new world is actually Reborn's biological daughter. One who he has no idea even exists (one night stands tend to leave people unaware).
