Synopsis

Yuki Joji, an ambitious scientist at Destron, faces a death sentence at the hands of Marshal Armor, who views him as a rival. He is slowly lowered into a pool of sulfuric acid, losing his right arm before being pulled back by colleagues who orchestrate a desperate escape. In hiding, Katagiri reaches out to his sister, a nurse, requesting her help with Yuki's cybernetic reconstruction. But Destron remains vigilant, dispatching Sickleneck-Tortoise to eliminate them.
