Under the dim moonlight, the Ninja Turtles patrolled the streets of New York, as they did every night, watching for any threats lurking in the dark corners of the city. Leaping from building to building, their senses remained on high alert. It was then that Leonardo stopped dead in his tracks, sensing a familiar and unsettling presence.

"It's close," Leonardo said quietly, his gaze fixed on the shadows.

The four brothers immediately unsheathed their weapons. Leonardo held his ninjatōs firmly, Raphael readied his sais, Donatello raised his bō, and Michelangelo twirled his nunchakus. They knew who they were facing: their sworn enemy, the female ninja of the Foot Clan. From the shadows, the female ninja appeared with a terrifying coldness, her expression hard and unfazed. The four brothers knew her well; she had a clear mission: eliminate Leonardo. The leader of the Turtles had to die, and she had accepted the task without hesitation.

Leonardo eyed her with distrust, preparing for the inevitable attack. The brothers stood on guard, ready for a battle. But what happened next took them completely by surprise.

With unexpected swiftness, the ninja advanced directly towards Leonardo. He raised his ninjatōs, prepared to block an attack, but instead, she roughly grabbed him by the front of his shell, pulling him towards her. Shock paralyzed him. Before he could process what was happening, the woman held her cold, rough gaze, and kissed him.

Raphael's eyes widened in fury. "What the hell are you doing?! I was supposed to kill you, not kiss you!"

Michelangelo was gaping, unable to articulate a word, while Donatello watched the scene with a mix of confusion and surprise. The tension in the air was palpable.

Shredder still wanted Leonardo dead, and his enemy wouldn't rest until her duty was done...or until something else threw her off course.
