Hametsu no Mars

Several months after a Mars probe disintegrates during reentry, mysterious creatures known as "Ancients" start appearing in Tokyo, exhibiting aggressive and deadly behavior that renders conventional weapons ineffective. As the scientific community scrambles to identify the cause of their sudden emergence, these monsters inflict devastation worldwide. Humanity's hope for survival lies in the MARS suit, a revolutionary weapon designed to combat the Ancients, but its operation is restricted to individuals with specific DNA. Takeru Hinata, a teenager with a tumultuous past, is among the select few capable of piloting the MARS suit, and he joins forces with the AAST, a specialized police unit established to counter the Ancient threat. As Takeru battles the monsters, he must also confront his personal demons and uncover the truth behind the Ancients' origins, all while fighting to save humanity from the brink of destruction.
