Nobody talks about this one. A fallen samurai turned into an immortal weapon tears through 1580 Japan while a ninja vendetta hunter pursues him across a landscape where future tech and feudal blades coexist, and the violence isn't stylized, it's blunt, anatomical, real. The story doesn't care about explaining itself; it just moves, kills, and ends before you catch your breath. This is pure 90s OVA excess: ninety minutes of blood and momentum, nothing more, nothing less.
Sixteenth-century Japan burns under Nobunaga Oda's conquest, where cutting-edge weaponry meets ancient tradition. Ginnai Doma, a samurai transformed into an unstoppable cyborg assassin, serves as the general's ultimate instrument of domination. His body rebuilt into a lethal engine of destruction, Ginnai executes anyone standing between Nobunaga and total control. Shishimaru of the Iga clan refuses to accept this new world. After watching his ninja brothers fall to Ginnai's blade, he breaks ranks with his own allies to pursue a solitary mission of vengeance. One warrior against an immortal killing machine. One oath against the tide of history itself. Black Lion fuses samurai codes with sci-fi body horror, creating a collision between the old martial world and technological transcendence. The action is brutal and uncompromising. Ginnai's cybernetic enhancements make him seem invincible, yet Shishimaru's desperation and ninja training offer an answer to brute force. This is a story about legacy, obsession, and whether conviction can overcome machinery.
