(Soft version) In the 84th year of the earth’s history, humanity has recovered from the Fourth World War and is exposed to a new threat!

A mysterious hostile object EOE that flew from outside the earth.
The unidentified black object preyed on all living things.
Each union deploys an army to intercept it, but the existing weapons are unable to deliver a decisive blow, and they are forced to defend themselves.
In response to this situation, Earth Governance Organization 8A launched an anti-EOE organization and introduced new weapons.
The battle between Earth and EOE has begun.
