In the year 2010 the Mars Exploration Vessel, returning to tell its secrets, fell to the Earth in a fiery blaze. Several months later, strange creatures known as Ancients walk the streets of Tokyo, brutally murdering anyone who gets in their way. In response to these incidents, the AAST – the Anti unidentified Ancients Special Team – has been created to subdue the threat. With the help of Hinata Takeru, a high school student who wears the Anti-Ancient Suit Mars, the AAST now sets out on a new mission: deliver the salvaged pieces of the fallen vessel into safe hands, at all costs!
It is the year 2023, 30 years since the time of the Silent Crisis that brought the world to the brink of destruction. In the present, other-dimensional beings known as the Lucifer Hawk are running rampant, and threaten to take over the human world. The only hope for mankind is the AMP -- the Attacked Mystification Police -- a group of women with paranormal abilities who are dedicated to stopping the Hawk at all costs. With the frequency of attacks increasing and the bodies piling up, it's up to Katsumi Liqeuer and the rest of the gang to stop the invading threat... before it's too late.
