Chase the Missing Nuke!
A shipment of plutonium is stolen, leading Tony to be accused of smuggling nuclear materials into Japan and having to give a statement before the Diet of Japan. In order to get away from the press, Tony hitches a ride with a reporter he had previously met, Nanami Ōta. Whilst investigating the ship where the plutonium was being transported, Iron Man encounters another Zodiac warrior, Cancer. Tony locates the culprits and drives them towards a security checkpoint, but he is blocked off by a self-proclaimed good samaritan named Nagato Sakurai. Nanami mixes her camera with the plutonium the culprits were carrying and is chased by an armored tank equipped with stealth camouflage. After Sakurai helps Iron Man deal with the tank, Iron Man faces off against Cancer again and defeats him. Tony's name is cleared and Nanami was able to write a good article.

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.
