Sword of the Demon Hunter: Kijin Gentosho

During Japan’s Edo period, a young boy named Jinta and his sister are forced to abandon their home, ultimately seeking sanctuary in a remote mountain village. As the years pass, Jinta matures into a formidable swordsman who pledges his blade to the priestess of the local shrine. When a malevolent demon emerges to threaten the sacred grounds, he ventures deep into the surrounding forest to destroy it. However, this fateful encounter shatters his understanding of the world when the creature reveals a startling truth: their battle is destined to reignite one hundred and seventy years in the future. This revelation transforms Jinta’s duty into an extraordinary pursuit that defies the boundaries of time. Bound by the demon's prophecy, he must carry his mission across multiple historical eras, hunting the entity through the centuries. Yet, as he traverses different ages to fulfill his oath, the relentless quest forces him to confront an even greater challenge—reconciling with the unsettling darkness hidden within his own soul. What begins as a simple vow of protection evolves into a sweeping epic fantasy, following a lone warrior whose fate remains forever entwined with the monster he swore to slay.
