Iron Will
Yinsen forces Chika to work on the arc reactor, before making his demands for the dissolution of the Armed Forces and National Diet. Nanami attempts to escape the hostage situation but is caught and thrown into a storage room. Tony is rescued by Sakurai and tries to contact Chika, but she is caught by Yinsen and throw into storage with Nanami. Meanwhile, the Defense Secretary Kuroda offers to be held captive in place of the hostages. As Chika and Nanami go through an air duct and retrieve Tony's armor, Tony and Sakurai are attacked by the Zodiac Saggitarius. Nanami gets the armor to Tony so he can defeat Sagittarius, before facing off against Yinsen. Just as Iron Man starts to get the upper hand when Yinsen hesitates attacking in front of Chika, someone overrides the Sigmas and attacks them both, with Yinsen getting critically wounded. Yinsen warns Tony that Zodiac's plan has just started.

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.
