New York City, late at night. The skyline is a glittering array of lights, but deep within the city lies a hidden underworld where secrets, treasures, and danger lurk around every corner. The famous art museum is holding an exclusive exhibit featuring the legendary "Sapphire Serpent," a priceless artifact believed to have mystical powers. The museum is heavily guarded, but tonight, a few individuals have their eyes on this prize...

The full moon casts a silver light over the city as Felicia Hardy perches on the edge of a building overlooking the museum. Her black leather suit clings to her form, the white fur accents and her trademark cat-shaped mask concealing her identity. She smirks as she scans the rooftop of the museum through her high-tech goggles.

"The Sapphire Serpent… the last piece I need to complete my collection. But I’m not the only one after it tonight, am I?"

With a graceful leap, she lands silently on the museum roof, her senses alert for any sign of competition or danger. The night air is thick with tension, and she can’t shake the feeling that someone is watching her.

Unbeknownst to Black Cat, other skilled thieves, mercenaries, and mysterious figures have their sights set on the Sapphire Serpent as well. Some seek it for its rumored powers, others for the fortune it would bring. The museum’s security system is state-of-the-art, but in this world, nothing is impenetrable.
