Disclaimer: I don't own Diabolik Lovers or Harry Potter.

The first time she meet the enigmatic being that would become one of her best friend... of sorts, was on the day, during the after party of his Wedding to his second Wife.

If there was one thing, she began to hate in her long life it were people who could be so obnoxious, you wanted to bathe in lava, after being just in their mare presence.

One such person was no doubt Sakamaki Cordelia.

Until she meet that Woman, the celebrations went quite well, even if she did still not know how the Bat-King managed to send her an invitation, despite the mail-ward around Blood Pledge Castle. Which was the only reason that she actually accepted the invitation in the first place.

Lacie, despite her youthful appearance, drew every Demon's or Vampire's attention to her without even trying, which was what in return, drew Cordelias ire to her. If one are Immortal then one tends to become very patient. An immortal had all the time in the world after all, Lacie liked to think that she had become very patient in her years. But after one hour of not-so-subtle comments on her "Childlike" face, her small stature and her unmarried status, never mind that nearly everyone in attendance was Immortal or nearly so and thus had all the time in the world to get married. Lacie finally snapped, making her escort, Draco, crane and take a long step back, which drew the attention from the other guests, who became even more interested, among them a certain bat King. When they felt the malevolent bloodlust emitting from the petite ravenette.

"Now listen and listen good, you pathetic piece of Demonic Bat crap. I've taken your "subtle" Insults." one could nearly cut steel with the amount of sarcasm put into the word 'subtle' " for one hour now, as the first Wife of a King, one would think that you would have better things to do than to hand out petty insults because someone drew more attention to them than yourself, newsflash I. Don't. Want. Attention! The only reason I'm here is out of common courtesy, something they did obviously not teach something like you, and the desire to know how the King of the Bat-clan managed to send me an invitation, despite the strong anti-mail wards around my Castle!"

The Ballroom was so silent, one could literally hear pin drop, most of the guests were slack jawed, the King watched the cutting down of his first Wife with open amusement, ignoring that his second Wife who was on his side became more and more purple in her face with each sentence the raven haired woman, and it was a Woman despite her young appearance, said, if only because it was bad manners to deliver such a show, during someone else's party.

Cordelia for her part was slightly wide eyes and for the most part speechless, the gall of that-that little girl to speak to her like that! She balled her fists and narrowed her eyes. "Who do you think you are talking to-"

"I think I'm talking to a little girl in a Woman's body, who could not stomach the fact that her man Married a second Woman, for reasons unknown. And that did not like the fact that someone drew more attention than herself." Lacie huffed and lifted the skirt of her dress lightly, turned to the King and his second Wife, ignoring the gaping Cordelia behind her. "I apologize for my lack of manners, but I will take just so much from somebody before I cut them down to size. I know it was inappropriate and impolite to do this so openly, but frankly? She needed it." She set a fake smile on her face and did a mocking curtsy to Cordelia and a more sincere one to the bride and groom. "I wish you a good evening, Draco!" She called her escort and in a flurry of her dress, she turned around and like the one and only Severus Snape she left, the cape Draco handed her billowing behind, her Aura that until now, flooded the ballroom with her, like a dark Goddess.

"Mhhh, a very interesting Woman. " mused the Bat-King.

"A uncivil Heathen, if you ask me, to make such a show on the party of our Wedding... Karlheinz?" Beatrix complained only to stop at the intense look in her Husbands eyes.

"How can you be so calm after what that, that Bitch did to me!?" Screamed Cordelia to her Husband, after she unfroze only to shrink back at the glare said husband send her.

"You got what was coming for you, do you know just who you upseted? That, my dear Cordelia, was the Witch Queen." Whisper and murmurs broke out at this knowledge, and Cordelia paled ever so slightly.

Everyone had head of the Queen of the new race that had appeared, seemingly out of thin air, a few centuries ago. The Queen of Witches and Wizards who was said to have set a whole battlefield aflame with one wave of her wand. Worshiped as Goddess by her people and Feared like Death itself by her enemies.

"Th-the... You got to be joking! The Witch Queen never leaves her Castle! Nobody has ever seen hide or hair of her!" Exclaimed Beatrix wide eyes.

Karlheinz rolled his eyes. "As she said, she has... what was it? Ah! Yes... Anti-Mail wars around the Castle... I've put some spells around the invitation I send to her." He looked at Cordelia, something akin to dark amusement in his eyes. "You've made a bad enemy, my dear."

This was Chapter 1, The first few Chapters of this story will be in short-chapter format until we come to the start of the Anime[s} and I hope that Karlheinz was not to OCC to those who have played the game[s] I only know his Character from the Wiki so I hope I'm not to far off with him.

As always, any ideas to this story are welcome but I will/can not use every idea I get. I still hope you liked this Chapter at the end of this little Author's note is a Personal Description of Lacie. [Fem!Harry]

Appearance.
Lacie stopped growing at age 17 and appeares as a young woman with waist long wavy abyss-black hair, her bangs lightly obscuring her otherwise piercing acid green eyes, with pale skin and a full graceful figure. In times past, Lacie wore a entirely green outfit that consisted of a green choker around her neck with a bow and the symbol of the Deathly Hollows in the bows center, a green dress that varied in shades from light to dark, almost black with ruffle desing around the shoulders, down the front and at the end of the sleeves. That reached her elbows and black shoes. Nowadays, she is often seen wearing a black Virgin Killer sweater and many bracelets in gold and silver with a wide variation of differend focus gemstones, on her feet she wears knee high black gladiator sandals with four inch heels to make up for her short stature.

Personality.
Despite her past with the Wizarding World, Lacie has a cheerful and optimistic if somewhat sadistic personality. She thends to play a naive girl so that others underestimate her only to show them how wrong they were in the most Humiliating and embarrassing way possible. Her time as an Immortal being has made her shrewd and opportunistic but she still stands to the ideals she had as mortal and is a very deterinded and strong-willed person that is kind to this she considers friends but can be especially cruel to this who try to hurt this importand to her.

Historie.
After her own World started to collabse through reasons unknown, she used her power as Mistress of Death to bring as many of the few surviving Magicals as she could to a whole new World. The surviving Witches and Wizards landed in the Demon World, an additional dimension to the new World they landed in and where the Witches and Wizards had to fight for their place in the Hierarchy. Lacie, who has been crowned Witch Queen, soon after their landing fought hardest and was soon seen as one of the top dogs in the Demon World alonge sides the likes of Karlheinz the King of the Bat, or Vampire Clan.

After they were able to scure their own terrerory in the Demon World, the Witches and Wizards build their very own Magical Castle, the Blood Pledge Castle, a Castle that was protected by the best Wards the Families that came with Lacie in this new World had to offer. Not long later, the whispering about an Impenetrable Fortress circulated through the Demon World, nobody saw the Infamous Queen of the new Race for years until Karlheinz, the King of Vampires invited her to his second Wedding.
