Hmm...

Hiroshi's heart pounded wildly, a jackhammer in his chest. Anger, pain, loss... all had merged into a single, burning determination. Alexi had killed his friends, Renji and Mai, without a shred of remorse. Now, he would pay.

"You're a monster!" Hiroshi screamed, his voice broken with pain. "You took everything I had!"

Alexi laughed, a cold, sharp sound like ice. "Everything? You haven't lost everything yet, Hiroshi. Not while you're still breathing."

The ground beneath Hiroshi's feet trembled. The digital arena, once so bright and futuristic, had transformed into a hellish landscape, an abyss of shadows and distortions. Alexi, at the center of that chaos, emanated an aura of dark power, an energy that made the blood run cold.

Hiroshi gripped the Light Katana, the blade shining with a blinding white light, the only source of hope in that sea of darkness. "I'll make you regret it," he promised, his voice a whisper laden with hatred.

Alexi moved an arm, and a wave of dark energy hurled towards Hiroshi. The boy, with surprising swiftness, moved aside, narrowly avoiding the attack. The energy struck the ground, opening a smoking chasm.

"You're fast," Alexi commented, his voice a hiss. "But not fast enough."

Another wave of energy, more powerful than the previous one, headed towards Hiroshi. This time, the boy couldn't avoid it completely. The energy struck his arm, enveloping it in excruciating pain. Hiroshi's arm turned into a mass of corrupted data, fragments of black code flashing like a broken neon sign.

"Ah!" Hiroshi cried out, the pain clouding his vision. Despite the pain, Hiroshi didn't give up. He used his good arm to wield the Light Katana, launching himself into the attack.

The blade of light darted through the air, cleaving the darkness. Alexi parried the blow with an arm, creating a barrier of dark energy. The Light Katana and the barrier clashed, generating an explosion of light and shadow.

Hiroshi, exploiting the moment of confusion, moved behind Alexi, trying to strike him in the back. Alexi, however, was too fast. He turned, grabbing Hiroshi's arm with an iron grip.

"You're pathetic," Alexi hissed, squeezing Hiroshi's arm tightly. "Do you really think you can beat me?"

Hiroshi, with a cry of rage, freed his arm from Alexi's grip, using the Light Katana to strike the enemy in the side. Alexi staggered back, surprised by the ferocity of the attack.

"Don't underestimate me," Hiroshi growled, his eyes glowing with a furious light. "I'll never give up."

The battle resumed, more intense than ever. Hiroshi, despite his wounds and pain, fought with fierce determination. Alexi, for his part, showed no signs of yielding, dominating the fight with his dark power.

Every blow, every parry, was an explosion of energy, a vortex of light and shadow. The arena trembled, the sky darkened, the air filled with sparks and smoke.

Hiroshi knew he couldn't last long. His wounds were severe, his energy was running out. But he wouldn't give up. He would fight to his last breath, until Alexi fell.

Revenge was the only thing that gave him the strength to go on. For Renji. For Mai. For all those who had suffered at Alexi's hand.

Hiroshi was exhausted, wounded, but his determination did not waver. Alexi, with a mocking smile, watched him, amused by his tenacity.

"You're surprising, Hiroshi," Alexi said, his voice a whisper laden with sarcasm. "But not strong enough. Not yet."

With a wave of his hand, Alexi unleashed a wave of dark energy, which enveloped Hiroshi, lifting him off the ground. The boy felt excruciating pain, as if his body had been torn apart and stitched back together.

When the energy dissipated, Hiroshi found himself standing, his breath ragged. He looked at his hands, astonished. His wounded arm had healed, the wounds on his body had disappeared. He felt different, stronger, faster.

"What... what did you do to me?" Hiroshi asked, his voice trembling.

Alexi laughed, a cold and cruel sound. "I gave you a little incentive, Hiroshi. A level up. You went from level 40 to level 100. Now you're my equal."

Hiroshi was stunned. Level 100? It was unimaginable power. But why had Alexi done it?

"Why?" Hiroshi asked, his voice a whisper. "Why did you give me this power?"

"Because I want to see you suffer," Alexi replied, his eyes glowing with an evil light. "I want to see you hope, believe you can win, and then tear it all away from you. I want to see you fall into utter despair."

Hiroshi felt a shiver of terror. Alexi was a monster, a sadist who fed on the suffering of others. But he wouldn't let himself be overcome by fear. He would use that new power to avenge his friends, to stop Alexi once and for all.

"I won't give you that satisfaction," Hiroshi said, his voice firm. "I'll destroy you, Alexi. I'll make you pay for what you've done."

Alexi smiled, a smile that promised destruction. "Try it, Hiroshi. Prove to me that you're worthy of my power."

The battle resumed, more intense than ever. Hiroshi, with his new power, lunged at Alexi, the Light Katana darting through the air like lightning. Alexi, however, was no slouch. With his dark power, he parried Hiroshi's blows, counterattacking fiercely.

The two warriors clashed, a whirlwind of light and shadow, an epic duel that would decide the fate of that digital world. Hiroshi, with his determination, his anger, his thirst for revenge, fought with unprecedented ferocity. Alexi, for his part, with his cruelty, his evil, his desire for destruction, did not back down.

Every blow, every parry, was an explosion of energy, an earthquake of data. The arena trembled, the sky darkened, the air filled with sparks and smoke.

Hiroshi knew it was a battle to the death. He knew that only one of them would survive. And he, Hiroshi, had no intention of giving up. He would fight to his last breath, until Alexi fell...
