What’s Wrong with a Bloodthirsty Loli Who Just Wants to Stab People?

[Pure yuri] + [Western Fantasy] + [Pure villain protagonist] + [Bloodthirsty] + [Dark] Also known as: A Killer Loli Wants to Collect Girls of Other Races Erika is a beautiful girl from the slums, and a serial killer feared by countless people: the Blood Elf. Her dream is actually quite simple: satisfy her urge to kill, then find the perfect toy, one she can do anything to without ever killing it. Then she finds a dying vampire girl. “You can drink my blood, if you agree to let me stab you a few more times every day!” A vampire scion with a twisted mind hidden within, and a gleeful maniac who wants to stick something into every living thing she sees. This pairing is practically tailor-made to wreak havoc on the world! Soon, Erika discovers that vampires are far from the only monsters in this world. A werewolf girl sleeping beneath a church... a ghost princess sealed away in a noble's collection room... a ghoul disguised as a nun, and a demon girl who claims she will conquer the entire continent but is so poor she has to eat dirt... And every one of them has a heart twisted to some degree. “Wow! They're all pretty monsters abandoned by the world! I've decided! From now on, you're all mine!” As all the girls of other races stare at her in bafflement, the little maniac, not even 1.4 meters tall, beams with childlike innocence. “Since none of us are exactly good people, why don't we turn this world upside down together? Having fun is what matters most~” “Come on, show me even more interesting ways to kill!”
