Space Defense Agency

The Space Defense Agency (abbreviation:S.D.A.) is a protagonist organization mentioned only in Aegius main series of shoot 'em ups. Founded when the Planetary Alliance was formerly renamed and replaced with this one due to the union with both the United Nations and Recom during the Space Nemesis era. It is an intergalactic military organization of space survivors that serves for earth, Aegius and the entire galaxy in their hopes to save the future from oppression similarly after the events of SVR, which is considered as prequel sub-series.

Space Defense Agency is responsible for focusing on galaxy-related operations in their hopes to protect humankind and kindness across the galaxy. However, when the entire universe is hopelessly oppressed by dark in the game sequence, they are dispatched at war with the misanthropic forces of a demonic alien race called the Hereticons, led by the evil cosmic mastermind and originated from the dark alien home world Hereticus chronologically right after the dissolution of the evil Hades Empire if P.A. had finally won the previous space wars.
