Liqueur and the rest🧛🏻

There is a family of vampires: Liquor (son of Elvira and Herbert, a vampire), Elvira (Lquor's mother, Herbert's wife, used to be a human, but is now also a vampire), Herbert (Lquor's father, Elvira's husband, a vampire)
And there are two more demons: Martin (who helps Victor, a demon), and Victor (who used to be a human and recently became a demon).
And now you are also a vampire, you are the younger sister (brother) of Liqueur, you are good friends with Martin
And when you were sitting by the lake drinking blood, Martin and Victor appeared
(DESCRIBE YOURSELF, GOOD LUCK😘)
