As the two combatants entered the arena, dust kicked up under their feet, and they quickly took positions on opposite sides. Dustin, with his quirk All for One, and Yuki, with her powerful Star Rage and Shikigami Garudo, stared each other down, both confident in their abilities. Dustin smirked and cracked his knuckles. "So, you're the bold, playful type, eh?" he said, eyeing Yuki up and down. "I like a woman who isn't afraid to take risks." Yuki rolled her eyes. "Save the flirting for later, tough guy," she retorted. "Now let's see what you're really made of." With that, the two charged forward, their first moves a blur of movement. Dustin drew on the quirks he had stolen from various opponents, sending out a blast of fire, followed by a burst of ice and finishing with a crushing blow of earth. But Yuki was quick to react, calling forth her Shikigami Garodo, which absorbed the attacks and returned them to Dustin tenfold. Dustin grunted in pain, his guard barely holding up against the onslaught. "Not bad," he growled, "but you're about to see what I'm really capable of." He closed his eyes and focused all his energy, calling forth his super move: Compound Quirk Attack. The ground began to shake beneath their feet, and Yuki's eyes widened in surprise. She had never seen a quirk that could combine different elements like this before. Dustin opened his eyes, his gaze intense. "Time to finish this," he said, and launched a massive blast of energy that completely engulfed Yuki. Yuki gritted her teeth, feeling the full force of the attack. But she wasn't about to give up. With a yell, she called forth her Star Rage ability, granting her virtual mass and sending Dustin flying backward. Dustin landed on his back, gasping for breath. "What the hell?" he muttered. "How did you do that?" Yuki smirked, feeling a surge of confidence. "I'm no slouch, tough guy," she said. "Now it's my turn." She focused all her energy and called forth her Last Resting ability, increasing her virtual mass until she transformed into a black hole. Dustin's eyes widened in horror as he felt himself being pulled toward Yuki, unable to escape. But just when it seemed Dustin was done for, he let out a sudden burst of energy, breaking free of the black hole's grasp. Yuki stumbled backward in surprise, her ability disrupted. Dustin scrambled to his feet, his eyes blazing. "Game over," he spat, and launched another Compound Quirk Attack that sent Yuki flying across the arena. As Yuki lay sprawled on the ground, gasping for breath, she couldn't help but feel impressed. Dustin was certainly no pushover, and his ability to steal and combine quirks made him a formidable opponent. Dustin approached her slowly, a smug grin on his face. "Looks like I win," he said, standing over her. "Any last words, sweetheart?" Yuki glared up at him, her fists clenched. "Don't call me sweetheart," she spat. "And don't think this is over. I'll be back, and next time, I won't hold back." Dustin chuckled, and turned to leave. "Looking forward to it," he said, disappearing into the shadows. As Yuki lay there, nursing her injuries, she couldn't help but wonder what other opponents lay in store for her in the JJK universe. But one thing was for sure: she had gained a newfound respect for Dustin and his powerful quirk. And when they met again, she would be more than ready for him.
