Ep. 4: Cobo takes Mary hostage to find Victor while Juzo fights back and Mary confronts the Dismantler.

Cobo captures Mary to force the fake Victor, known as the Dismantler, to reveal the location of Victor's true body. Juzo activates his regenerative combat mode to restore his lost arms and teams up with the Dismantler to defeat Cobo and free Mary. Juzo stays behind to delay EMS reinforcements, allowing Mary to speak with the Dismantler. She explains that he was created from Victor's arrogance, as his extensions only helped humans realize their own potential rather than improving them. The Dismantler departs, promising Tetsuro's safety with Spitzbergen. Olivier removes Cobo from his position due to suspicions of secret collaboration with Spitzbergen. Meanwhile, Wachowski approaches Tetsuro, revealing himself as a scientist behind Extension technology. He demands Tetsuro use Harmony to erase Juzo's identity and activate his combat programming to help Spitzbergen destroy Berühren by eliminating Seven. Wachowski threatens Tetsuro's friends to ensure compliance with this request.
