Reborn as a Vampire Princess, I Aim to Be a Slacker Supervillain

I woke up as a cute, white-haired vampire princess? And I even awakened a System that seems a little off? Hey, hey! Why is someone luring monsters to my house right from the start? The little vampire princess accepts her mission: become the greatest villain in the world and do her best to survive to the end! Gender bender, two female leads, pure love, System, villain (Ugh, I got the tags wrong, but I can't change them now that I've signed the contract.)
