In the twilight of the Sengoku era, where warlords wage endless battles for power, a lone samurai
named Ryūnosuke Kurogane walks the path of vengeance. Betrayed by his own clan and left for
dead, he is resurrected by the spirit of Yami—an ancient, cursed shadow that feeds on the hatred of
fallen warriors.
Now bound to the darkness, Ryūnosuke must carve his way through treacherous war-torn lands,
hunting the warlords who conspired against him. But with each enemy he cuts down, Yami's
influence grows stronger, threatening to consume his very soul.
Will he control the darkness within, or will he become the very demon he swore to destroy?
