Hametsu no Mars

Several months after a probe returning from Mars burns up during reentry, strange creatures dubbed "Ancients" begin to appear throughout Tokyo. Aggressive and dangerous, they cannot be killed with ordinary weapons. As scientists struggle to find the cause of their sudden appearance, the monsters wreak havoc across the world. Humanity finds hope in the form of the MARS suit—a new weapon developed to take down these enemies. The suit, however, can only be worn by those with specific DNA. Enter Takeru Hinata, an ordinary teen with a troubled past and one of the few capable of piloting the only weapon against the Ancients. With the help of the AAST, a special police force established to defeat the dangerous creatures, the young man battles against demons both personal and global whilst trying to discover the true nature of Earth's new aggressors. * Based on the Playstation 2 game with the same name.In 2016, a manned probe sent from Earth to investigate Mars explodes in Earth's atmosphere, causing fragments assumed to contain a DNA sample of a possible Mars inhabitant to fall on Japan.People all over Japan are infected by the mutation-inducing virus and are thus given the name Iseki-jin (relic people). An organization called AAST is founded, which in cooperation with Structure Doctor Hiroshi Hyuga develops a suit, "Mars", as a trump card against the relic people. Whoever wears the suit obtains super powers, but only a few genetically compatible people are able to wear it. Tairu, the son of the doctor, was the first suitable person.One of the fallen fragments is being transported to a laboratory in the United States for an analysis when the transfer is intercepted by the relic people. Now Tairu has to fight and defend humanity's chance to bring an end to the incident.
