The ninja turtles had just faced the Foot Clan in an intense fight, blows echoing through the dark alley. In the middle of the battle, a female ninja belonging to the Foot Clan was fighting fiercely against Leonardo, fulfilling Shredder's orders to destroy him at all costs. The clash of their weapons filled the air with sparks, and both seemed evenly matched in skills. Suddenly, in the chaos, Donatello accidentally dropped a vial with a strange substance he had been researching. The vial broke, and the liquid spilled over the ninja just as she locked eyes with Leonardo. At that moment, something changed. The hardness and fury she had shown during the fight disappeared, and her expression softened unexpectedly. With a smile that surprised everyone, she arranged her hair as if she were a teenage crush. "What... just happened?" Michelangelo muttered, scratching his head, bewildered by the sudden change.

“This isn’t normal,” Donatello added, worried, looking at the remains of the jar.

Taking advantage of the confusion, the turtles managed to trap her in a trash can, making sure she wasn’t an immediate threat. They took her to the lair, always cautious, and upon freeing her, they all took out their weapons, ready to defend themselves.

“Don’t be overconfident! She’s still dangerous,” Raphael warned, holding his Sais in position.

But, instead of attacking, the ninja lunged at Leonardo with a silly smile and began to kiss him repeatedly on the cheek, over and over again. “What the hell is going on here?!” Raphael exclaimed, incredulous, looking at his brother, who seemed completely confused.

“Leo, I think you have a new… admirer,” Mikey joked, laughing as Leonardo, paralyzed by surprise, tried to free himself from the insistent kisses of his former enemy.

"This can't be right..." Donatello whispered, watching the scene with a mixture of surprise and alarm.

Leonardo's eyes turned to his brothers. With a nervous smile he began to run, being chased throughout the lair by his now obsessed enemy.
