Iczer-1 fights Iczer-2 in a massive battle over the ruins of Japan and is defeated, but escapes to regroup with Nagisa and rescue her. Iczer-2 and Sepia arrive in their giant robot, Iczer-Sigma. Iczer-Robo appears, and Nagisa leaves Sayoko with her bracelet before going with Iczer-1 to fight. Again the battle goes poorly for Iczer-Robo until, in a fit of sadism, Iczer-2 stomps on Sayoko, who has come to watch. Immediately Sepia's morale is broken and Nagisa once again triggers the beam weapon of Iczer-Robo, destroying Iczer Sigma. Iczer-2 barely manages to teleport away before the robot explodes. Sepia chooses not to escape, wanting to be reunited with Cobalt.
