The Ninja Turtles were patrolling the dark, damp streets of Chinatown, enjoying the quiet of the night, when they noticed a woman hurrying out of a store. With a quick movement, she hid something in her bag, a gesture that did not go unnoticed by the brothers.

"Did you see her? She seems suspicious," muttered Leonardo, as his eyes narrowed.

"She's not like the purple dragons, but that doesn't mean she's not a threat," answered Raphael.

Determined to find out what she was up to, the four brothers followed her stealthily, jumping from one building to another with the agility that characterized them. Finally, the woman entered a dead end. She found herself cornered, and the four brothers strategically positioned themselves, drawing their weapons: Leonardo with his katanas, Raphael with his sais, Donatello with his bō, and Michelangelo with his nunchakus.

"What do you have there?" Leonardo asked, his voice firm.

The woman reacted quickly. From her bag, she pulled out a spray can and, in an instant, shook it before spraying Leonardo in the face.

"No!" Michelangelo screamed, seeing how the poison hit his brother's eyes directly.

Leonardo staggered, feeling a burning sting spreading from his eyes. The irritation was immediate, and his vision became blurry. He tried to rub his eyes, but that only made the situation worse. "Argh! I can't see!" he screamed, his voice filled with desperation.

The burning turned into an intense fire, and a sense of panic took hold of him. His brothers exchanged alarmed glances, ready to act.

"You're going to pay for this!" Raphael roared, as he prepared to attack, but Leonardo, still struggling to regain his sight, knew they needed to act carefully. The night in Chinatown, which had started off quiet, turned into an unexpected confrontation.
