As the two fighters entered the arena, Kaoru Hanayama and Wakatsuki Takeshi sized each other up. Kaoru was unimpressed, his stoic expression giving nothing away. Wakatsuki, on the other hand, was practically bursting at the seams with energy. "You look tough, kid," Kaoru rumbled, cracking his knuckles. "But don't get too cocky." Wakatsuki didn't seem to hear him. He was bouncing on the balls of his feet, his eyes glued to Kaoru's imposing figure. The bell rang and the two fighters sprung into action. Kaoru charged forward, his massive fists raised. Wakatsuki calmly sidestepped the attack and grabbed onto Kaoru's arm, twisting it behind his back. Kaoru grunted in pain, but didn't give up so easily. He powered through the hold, grabbing onto Wakatsuki's arm in turn and twisting it with all his might. Wakatsuki gritted his teeth, feeling the pressure on his bones. But he used his superior strength and threw Kaoru to the ground in a powerful sweep. Winner: Wakatsuki Takeshi Wakatsuki's throwing and grappling techniques were superior to Kaoru's brute strength. Kaoru was unable to adapt and was ultimately overpowered. Kaoru stood up, shaking his head slightly. He had underestimated his opponent. "Not bad, kid," he grunted. "Can you take another hit?" Wakatsuki simply grinned, his muscles pulsing with energy. "I'm just getting warmed up, old timer," he shot back. The two fighters charged at each other again, this time with more caution. Kaoru unleashed a powerful punch, but Wakatsuki dodged it and landed a solid blow to Kaoru's stomach. Kaoru stumbled back, but quickly regained his footing. He threw a flurry of punches and kicks, but Wakatsuki was too quick for him. In the end, Wakatsuki landed the final blow with his signature technique "Blast Core", building up tension and pressure in his muscles before unleashing it in one powerful strike. Winner: Wakatsuki Takeshi Reason: Wakatsuki's superior speed and technique, as well as his special move "Blast Core", allowed him to out-maneuver Kaoru and land the final blow. Kaoru's brute strength was no match for Wakatsuki's skill.
