The gladiator coliseum erupted in cheers as Noctis Ravenscar, the Forbidden Element Brother, and Ryo Mizuki, the Aqua Sovereign, stood at opposite ends of the arena. The two combatants eyed each other warily, each sizing up the other's abilities. "Ah, the infamous Noctis Ravenscar. I've heard much about you," Ryo taunted, twirling his katana, Tidecaller, in his hand. Noctis snarled in response, his eyes flashing red with vengeful fury. "You will pay for the sins of your kind, Aqua Sovereign. You and all those who stand with you." Without warning, Noctis charged forward, his gauntlets made of blood glowing brightly. Ryo didn't flinch, his eyes locked onto his opponent as he waited for his chance to strike. Noctis launched his first attack, twisting his hands to create a crimson bind around Ryo's wrists. Ryo gritted his teeth as he struggled to break free, but the blood magic was too strong. Noctis raised his other hand, ready to strike with a deadly blow. But Ryo was faster than he thought. In a blur of motion, Ryo lunged forward and sliced through the blood bind with his Tidecaller, sending droplets of crimson flying in every direction. Noctis stumbled back in surprise, his eyes wide with shock. He had never encountered someone with such skill before. Ryo didn't let up, charging forward with a fierce Aqua Slash. Noctis barely managed to dodge, his speed just barely keeping him one step ahead of Ryo's deadly blade. Noctis countered with a Blood Arrow, sending a stream of thick blood racing towards Ryo. Ryo spun away from the attack, twirling his katana above his head as he prepared to unleash his next move. Without warning, Ryo summoned a massive Tidal Wave, sending a wall of water crashing towards Noctis. Noctis was knocked off his feet, struggling to stay afloat amidst the rushing water. But Noctis was no pushover. With a wave of his hand, Noctis summoned a torrential downpour of blood spikes, raining down on Ryo with deadly accuracy. Ryo gritted his teeth as the spikes splashed against his water shield. He knew he had to act fast if he wanted to take down Noctis. With a fierce cry, Ryo summoned another Aqua Slash, slicing through the blood spikes with ease. Noctis stumbled back, his face contorted with anger. The two combatants circled each other warily, each waiting for an opening. Ryo's eyes flicked down to his katana, carefully assessing his next move. Then, without warning, Ryo charged forward, his body propelled by a burst of water. Noctis barely had time to react before Ryo was upon him, his Tidecaller poised for the final blow. Noctis swung wildly with his blood gauntlets, but Ryo was too quick, dodging each attack with ease. Then, with a final burst of speed, Ryo sliced through Noctis's gauntlets with his katana. Noctis staggered back, his eyes wide with shock. Then, with a fierce cry, Ryo delivered the final blow, plunging his katana deep into Noctis's chest. The crowd erupted in cheers as Noctis crumpled to the ground, defeated. Ryo stepped back, his katana still dripping with blood. "That's what you get for messing with the Aqua Sovereign," Ryo muttered, his eyes dark with satisfaction. He had emerged victorious, and nothing could stop him now.
