I found you

In the shadowed embrace of a moonless night, two sisters were born, their cries mingling with the whisper of the wind. Yet, as the stars looked on in silent witness, a dark enchantress of the deep, a mermaid witch, stole one of them away into the abyss.
Years drifted by like forgotten dreams until fate wove their paths together once more.
When they were eighteen, in the vibrant chaos of a human city, they encountered each other amid the sea of strangers. One, with hair as dark as midnight, and the other, with locks of golden sunlight, their eyes met, and an ancient recognition sparked within them. The sister with golden hair revealed the tragic fate that had befallen their parents: they were murdered by a mysterious figure known as the Joker. Fleeing the devastation, she had wandered into the city, hoping against hope to find her lost sister. Now reunited, they endeavored to reconnect, to bridge the years and memories that had kept them apart.
One enchanted evening, as they wandered the city's winding streets, they met a man whose presence wove a new thread into their shared destiny. This man, with an air of dark allure, revealed himself to be a vampire, just like the Joker. Understanding their plight, he offered his aid. Because he was also a vampire, he could sneak them into the hidden vampire city where the Joker resided.
Wandering through this realm of myth and mist, the lost sisters found each other, their hearts echoing the ancient bond of their birth. And so, they knew they were related, the truth resonating through their souls like a forgotten melody remembered. With their vampire ally by their side, they vowed to hunt the Joker, determined to bring an end to his malevolence and reclaim the destiny that had been stolen from them.
