As soon as the match started, both fighters stepped forward, observing each other. The silence of the plane was broken by the clatter of Guts' Dragon Slayer hitting the ground. "I'll make this quick," he growled, unsheathing the blade. "You're dead before you know it." You smirked, his eyes unblinking and unfazed by the threat. Without warning, he lunged forward, throwing a flurry of blows towards Guts. However, Guts was fast and agile, dodging each punch and swipe effortlessly. Knowing that the attacks were not effective, You took a step back, preparing for his next move. Suddenly, You's body went through a series of disruptive spasms. His limbs and muscles contorted, morphing into a grotesque form. It was a body manipulation skill that he had used before, but this time, he took it to a new level. He became almost unrecognizable, his body warped into a horrifying shape that towered over Guts. Guts raised his sword, tensing up for the next attack. Despite the transformation, he remained calm and focused. You charged forward, ready to crush Guts with his newly-formed limbs. However, Guts used his instincts, quickly dodging and weaving between the attacks. With his inhuman strength, he launched a few slashes of his great sword toward You's massive body. Despite being hit multiple times, You shrugged off the attacks and prepared to strike back. As You charged forward, Guts used his wit and cunning, kicking up dirt and gravel toward You's face. The dirt blinded You, and when he swung blindly, Guts moved closer and thrust his sword forward. The attack hit the mark, piercing through You's chest. Guts pulled the sword out, ready to strike again, but You didn't fall. Instead, he stood there, grinning. "That's too bad," You taunted. "I was just getting warmed up." As You's wound healed, Guts was stunned. He had never seen such a recovery before. You had adapted to the situation and made himself almost invincible. However, Guts refused to back down. "You're still no match for me," Guts growled, determined to finish the fight. A fierce battle ensued with both fighters giving and taking vicious blows. Despite Guts' strength, You's limitless power and resilient body seemed to have no equal. Guts even tried to trigger the berserker armor, hoping to gain the upper hand. But You kept coming, absorbing the hits with ease and dishing out more damage. As the sun began to set, a deafening silence hung in the air. The two fighters were locked in a stalemate, each refusing to give in. Finally, Guts saw an opening. As You launched a series of strikes, Guts dodged and countered with his sword. He kept hitting You over and over, striking with precision and power. You seemed unstoppable, but the barrage of attacks finally took their toll. He staggered back, panting heavily. Guts could hear You's breath becoming weaker and more ragged. Winner: Guts Despite You's incredible resilience and nearly unlimited power, Guts' sheer strength and determination finally wore him down. Guts' sword strikes and mental fortitude were too much for You to handle, resulting in his eventual downfall. In the end, Guts' fighting spirit proved to be the deciding factor in the fight.
