Shuji, a veteran who had spent his life racing across battlefields and crossing countless lines of death, finally succumbed—not to an enemy’s blade, but to the weight of the grudges carried by those he had slain with his own hands. When his eyes opened again, he was no longer the war-hardened soldier everyone feared. He had somehow returned to his youth, back to the days when he was just a nameless boy doing menial work, before he had ever earned glory in battle.

In that moment of disorientation, one memory rose above all others: Ko Eiyou. She had once been his comrade-in-arms and his savior, the one person he owed more than he could ever repay. Determined to see her again, Shuji sought out the Tiger Pit Sect, where she had belonged. But instead of the formidable warrior he remembered, he found only a cheerful, innocent girl—untouched by the tragedies that awaited her.

Shuji knew what the future held. A noble family’s conspiracy would destroy her clan, forcing her to take up arms and march into a life of blood and sorrow. She would become the soldier he once knew, but only after losing everything.

“This time,” Shuji swore, “I’ll protect her. No matter what it takes.”

To repay the debt of his past life and to shatter the chains of fate, the old soldier once again takes up his spear and steps onto the battlefield—ready to fight like a demon for the sake of the one person he could not save before.
