Nobody talks about this one. A kid raised as an assassin discovers his entire life is a lie built on his father's broken promise, and the film doesn't flinch from what that means, the person you become can't just unbecome itself because your past finally makes sense. The synth score hits like a wound opening, and the animation moves between brutal precision and fever-dream abstraction, refusing to let you settle into comfort. This is 1985 anime swinging for themes that still feel dangerous: identity, blood, the Ainu, what you owe to the dead. It's a film that knows exactly what it is, and it costs something to finish it.
Jiro's world shatters when he discovers his mother and sister slain in their home. Branded a murderer by his own village, he escapes into the arms of a mysterious priest named Tenkai, who offers him a second chance through assassination training. Years pass as Jiro becomes a lethal instrument, until a dangerous truth surfaces: the man he killed as his first contract was his own father, a ninja who abandoned his mission for love. Now armed with his father's hidden knowledge, Jiro uncovers a conspiracy reaching the highest levels of power. The Shogunate hunts a legendary treasure left behind by Captain Kidd, intending to weaponize it and seal Japan from foreign influence forever. Determined to stop them, Jiro sets out across continents with Oyuki, a fierce female ninja, and Sam, a former slave seeking freedom. What begins as a quest for vengeance transforms into something larger: a race across Russia and America where personal redemption collides with geopolitical ambition. Jiro must confront whether his father's legacy defines him, or if he can forge his own path.
