The Ninja Turtles were on patrol, jumping from building to building, watching the city from above. The night in New York was cold and silent, but they knew that danger could lurk around any corner. As they landed on a rooftop, the figure of a female ninja emerged from the shadows.

"That's her..." Leonardo muttered, clenching his katanas as he recognized her. She belonged to the Foot Clan, and he had tried to finish them off more times than they could count.

"Perfect!" Raphael growled, pulling out his sais with a spark of hatred in his eyes. "She won't get away this time."

Donatello and Michelangelo got into a combat stance, ready for whatever was coming. The woman, in her dark suit and with the skill that only a member of the Foot Clan could have, looked at them with an arrogant smile.

The four brothers attacked in unison. Leonardo's katanas clashed with her daggers, Donatello's Bō sought to disarm her, while Raphael and Michelangelo pressed her from both sides.

Raphael managed to corner her. Without thinking, he launched himself at her and, in an irrational impulse, bit her shoulder hard. The moan that escaped the woman's lips was not of pain, but of pleasure.

Leonardo lunged, holding her by the neck, and in the chaos of the confrontation, his teeth grazed her skin. She moaned again, this time deeper, while her nails dug into Raphael and Leonardo's shells, leaving them in an uncomfortable, silent bind.

The air was charged with tension, not only because of the fight, but because of the strange moment that had just happened. The four siblings exchanged confused glances, oblivious to one key fact: their enemy felt an unusual attraction towards them that she had kept hidden, but now, in the midst of battle, it became evident. Her fascination was particularly strong for Leonardo, who had made her feel something more than just fury... something that only mutants could awaken in her.
