The Light in the Distance
Kuroda enacts a coup d'etat and declares martial law over Japan. Meanwhile, Chika admits to Tony that she's been having blackouts and has been controlled into altering the arc reactor, wanting to commit suicide for causing Tony's suffering. Just then, Kuroda approaches them in his Retetsu armor and takes control of Chika, who had really been a Zodiac warrior, and has her attack Tony. As Tony tries to get Chika to believe in herself, she stabs herself to break free from Kuroda's control. Tony leaves Chika in Nanami's care whilst he goes to fight Kuroda, who was resentful due to his grandparents being killed in the Nagasaki bombing. Meanwhile, Chika decides to transfer her consciousness into the arc reactor program in order to take control of it and transfer its energy over to Iron Man. Iron Man manages to defeat Kuroda with the power provided, but Chika dies as a result of the transfer. A month later, the Arc Station is finally activated, providing clean energy for Japan.

Iron Man
Tony Stark, CEO of a large weapons manufacturer, physicist, engineer, and brilliant inventor, is wounded by shrapnel from one of his own weapons. While held captive by terrorists, he develops the Iron Man Suit and escapes. From that day on, he vows not to waste his second chance at life and to change the world for the better. For that purpose, he comes to Japan.
In Lab 23 in Japan, great strides have been taken to develop, and build, a unique power station which does not run on fossil fuels, the Arc Station. Stark intends to join this project, and, for that, he is ready to announce his retirement as Iron Man. At the same time, he will also announce the Mass-produced Iron Men, to which he will pass on his duties. However, during the ceremonies, Stark is suddenly attacked by combat mecha belonging to an organization known as Zodiac.
