The wind blew calmly as Ren stood in the center of the training arena. His blade was raised, ready to land the final blow on his opponent, whose sword had been cleanly cut in two and lay several steps away.

  Ren’s breathing was steady. His posture was perfect—everything just as he had been taught.

  No strike overdone.

  No energy wasted.

  The Kurogane sword style demanded precision and focus above all else. That was the way of the Kurogane.

  “Finish him.”

  The command echoed from the high seats. Ren did not look up. He already knew whose voice it was.

  His gaze dropped to the crimson ground, darkened by the prisoner’s blood. His hands trembled.

  The blade vibrated softly, a chilling hum crawling up his spine. It felt as though the sword wanted something—something from inside him.

  A dead silence swept through the arena as Ren envisioned his final strike.

  The angle.

  The distance.

  Everything perfectly calculated.

  As he moved to kill his opponent, he suddenly stopped—frozen in time.

  Memories of his older brother Kaien flooded his mind. He remembered how Kaien had killed his first opponent in this very arena. Precision. Focus. No hesitation. He had followed the Kurogane way perfectly… and had done the one thing Ren could not bring himself to do.

  Kill.

  Ren steadied himself and raised his blade again. Then the promise he had made to himself surfaced in his mind.

  My sword shall only be used to protect what I believe is right.

  And killing a defeated man was not right.

  Yet when you are a Kurogane, your worth is measured by one thing alone—how well you perform on the battlefield.

  With resolve hardening in his chest, Ren thrust his sword into the ground and lifted his head.

  “I will not kill.”

  A ripple of murmuring devoured the arena like a predator consuming its prey. The tension was so thick it felt like a blade pressed against the heart.

  One of the elders rose. “Ren,” he said sharply. “What did you say?”

  Ren did not hesitate. His decision was set in stone.

  “I will not kill.”

  The murmurs grew louder. This was no ordinary training session—nor a simple test of strength or technique. This was a test of resolve.

  Suddenly, Kaien stood from his seat.

  “A blade that cannot kill is not a blade—it is a lie!” he shouted. “We, the Kurogane, believe the blade must never hesitate. It is either you kill… or you are killed!”

  Ren met his older brother’s gaze without flinching.

  “We do not live to serve the blade,” Ren replied calmly. “The blade lives to serve us. There is no need to kill this man. I have already won.”

  Turning away, Ren began to leave the arena.

  In an instant, Kaien leapt from his seat, intent on striking Ren down. Tetsuyu, Ren’s second brother, moved to intercept him—

  “Enough!”

  The elder’s command thundered through the arena.The atmosphere shifted. The ground trembled beneath their feet. The expressions on the elders’ faces darkened.

  The crowd murmured until silence was demanded once more. One of the elders stepped forward and fixed Ren with a cold stare.

  “Every training ends with judgment.”

  Ren lifted his chin. “Then judge me.”

  As he reached for his blade, a sharp pain shot through his arm. The sword felt wrong—not dull, not heavy, but wrong. A strange surge of energy erupted through the arena, unseen by most.

  A single voice whispered, “The blade remembers.”

  Ren did not understand what it meant.

  But deep within the history of the Kurogane, something had begun to awaken—

  and it would change the course of the future forever.
