Shuji, an old veteran who spent his entire life prowling the battlefields, finally met his end, consumed by the vengeful grudges of those he had slain.
When he opened his eyes again, for reasons unknown, he had regressed to his childhood as a lowly porter—a time before he had even begun to learn martial arts.
Driven by memories of Ko Eikou from his previous life, Shuji made his way to the Tiger Pit Sect, only to find a version of her that was worlds apart from the woman he had known in the army; she was pure, cheerful, and innocent.
He soon discovered that her family had been destroyed by a rival clan's conspiracy, forcing her to flee and enlist in the military as a last resort.
Seeing her so untainted, Shuji vowed to repay the debt of kindness he owed her from his past life.
He resolved to take his revenge on those who had ruined her life once—and those who were destined to do it again.
