Kazuki's heart raced as he spotted the monstrous horde charging toward him, their twisted forms illuminated by the moonlight. “I can’t let them get away!” he thought, excitement swelling within him. But as he sprinted after them, a searing pain shot through his body, causing him to scream in agony. "Aaaagh!"

The creatures halted, their grotesque heads turning toward the source of the sound. "Get him!" they growled, surging forward. Just when hope seemed lost, the four figures that had healed him before stepped into the fray.

The strongest among them, Sato, spoke with a commanding tone. “Good job for holding them back, Kazuki. It’s our turn now!”

Kazuki's vision blurred as he fainted, succumbing to the pain.

When he regained consciousness, he found himself back in bed. The scent of herbs filled the air. He blinked against the dim light, seeing three beautiful girls—healers, he guessed—surrounding him.

“You’re awake!” one of them exclaimed, her eyes sparkling with concern. “How are you feeling?”

Kazuki sat up, wincing at the remnants of pain. “I... I’ll be fine. Who are you?”

The girls exchanged glances before the one with long, flowing hair smiled. “I’m Aira, and these are my friends, Sam and Ayane. We’re part of the team that saved you!”

Kazuki’s heart warmed at their kindness. The group shared lighthearted chatter, and he felt a glimmer of hope for the first time in ages.

Days turned into weeks as Kazuki adjusted to his new life. Sato became a mentor, guiding him through rigorous training. “You want to become stronger, Kazuki? Let’s push those limits!” Sato declared, a fire igniting in his eyes.

Kazuki agreed, taking on the challenge with determination. “A hundred push-ups today, two hundred tomorrow!” he promised himself. Each morning began with grueling exercises, and though he thought it would be easy, his body soon cried out in protest.

"Ugh!" Kazuki grunted one day as he faced a sturdy tree, his fists clenched in fury. With each punch, he felt blood seep from his knuckles. “Come on!” he growled, losing himself in the rhythm of destruction. “Just… a little more!”

Two hours later, he finally shattered the tree. Panting, he turned to his adopted family, who watched with a mix of concern and pride.

“Kazuki!” one of them gasped. “You’re hurt!”

He grinned through the pain, the crimson droplets on his hands gleaming in the sunlight. “It’s all part of the process!” he said, determination blazing in his eyes.

Three years passed, and Kazuki transformed into a powerful warrior, his body hardened through relentless training. One day, Sato approached him with a serious expression. “Kazuki, we need to talk about sealing your powers.”

“Seal my powers? Why?” Kazuki asked, confusion clouding his thoughts.

The narrative has been taken without authorization; if you see it on Amazon, report the incident.

“Your strength is growing too quickly. You can’t control it yet,” Sato explained, producing a cloth infused with powerful spells. “It will help keep your powers in check.”

Kazuki hesitated but ultimately agreed, knowing Sato only wanted what was best for him.

Then came the fateful day when Ayane announced her decision to join the royal knights. “I need more money,” she declared, a greedy glint in her eyes.

“The king recognizes your strength, Ayane,” Sato said, wary of her choice. “Be careful.”

Weeks later, chaos erupted. Kazuki’s heart raced as he sensed an ominous presence. Suddenly, the king himself stood before their home, flanked by his two guards. “Ayane,” the king commanded, “kill Kazuki.”

Before Kazuki could react, Ayane drew her dagger, stabbing Sam and Aira without hesitation.

“No!” Kazuki shouted, but it was too late.

Sato roared in anger, “Ayane, you traitor!” He charged at her, fists ready for battle.

As the fight ensued, Kazuki’s heart sank, grief and rage surging within him. Sam, bloodied and defeated, gasped, “This wasn’t the plan! I thought it was only the new kid!”

The betrayal stung deeply, reigniting the pain of his past. With a cry filled with fury, Kazuki yelled, “I should not have trusted you!” and, in an instant, struck Sam down himself.

The fat guard laughed as he turned to Kazuki, his fists raised. “You think you can stand against me? You’re nothing!”

Kazuki gritted his teeth, recalling the pain from his training. He charged forward, throwing punch after punch, each strike echoing with a sickening “Thud!” as his fists met flesh. But the pain returned, sharper than before. “I won’t back down!”

But with each attack, his energy waned. The fat guard landed a blow, sending Kazuki sprawling to the ground. “Is this all you’ve got?” the guard jeered, looming over him.

In a desperate moment, Kazuki glimpsed the sealing cloth wrapped around his fists. The guard smirked, yanking it away. “Let’s see your true power!”

Kazuki felt an immediate shift in the air, a weight lifting as his true strength surged forth. “Where are you going, fatso? Come and fight me at my strongest!”

The fat guard froze, fear flashing across his face as Kazuki’s power enveloped him. With a roar, Kazuki launched himself at the guard, delivering a single, devastating blow that echoed in the night. The guard crumpled, blood spraying in a crimson arc.

“Kazuki!” Sato shouted, still locked in battle with Ayane. But Kazuki's victory was short-lived. Ayane, grinning, said, “You’re not done yet, are you?”

Kazuki charged, his fists ready. But as Ayane summoned a massive stone barrier, he felt the heat radiating from it. “I won’t let you escape!”

With a primal roar, Kazuki struck the stone twice, the sound of shattering echoing in the night. “Crack! Crack!” Pain coursed through his body, but he pushed through, determined to break her defenses.

In a moment of desperation, he spotted an opening and lunged for Ayane’s torso, his fist colliding with her ribs. “This ends now!” he yelled, but Ayane laughed, her wounds healing before his eyes. “You think that’s enough?”

Kazuki’s heart sank as he felt a sharp pain in his left arm. “No...!” he cried as it fell to the ground, severed.

“DIE, you cursed being!” the king bellowed, casting a dark spell that crackled with energy. Kazuki braced himself but didn’t dodge. Sato jumped in front of him, deflecting the attack. “RUN, Kazuki!”

Kazuki staggered back, fear and anger coursing through him.

When Kazuki awoke two days later, the sun streaming through the window, reality hit him like a hammer. Sato had sacrificed himself. “It was supposed to be me!” Kazuki shouted, grief choking him. Tears streamed down his face as he mourned his fallen brother.

“You’ve got the greatest potential and determination,” Sato had said before passing. The words echoed in Kazuki’s mind as he buried Sato’s body, vowing to avenge him. “I will avenge you, brother.”

Kazuki stood by the grave, the weight of his sorrow heavy on his shoulders but burning with newfound resolve. He clenched his fists, knowing the battle was far from over.

“I’ll make them pay,” he whispered into the wind, the shadows of his past merging with the promise of vengeance. “This isn’t the end.”
