Cyborg 009: Kaijuu Sensou

After breaking free from Black Ghost, the nine cyborgs scatter across the world and try to build peaceful lives. Their fragile calm ends when a gigantic creature begins attacking cities with devastating ultrasonic waves. Dr. Gilmore suspects that their old enemy has returned and calls the team together once more.

A young woman named Helena, who claims the monster destroyed her home, joins their search as the cyborgs set out aboard the Dolphin. The trail leads beneath the sea toward a new Black Ghost operation, where monstrous weapons and hidden motives await. For Joe Shimamura and his companions, stopping the creature means confronting the organization that stole their humanity all over again.
