Here’s the premise of the OVA from the work’s official website:

In the near future Garrett Oswald a brilliant scientist creates the Cygens, by combining organic cells with inorganic components. With the assistance of a highly sophisticated computer running specialized software implanted in the human brain, a subject can learn to completely control their own cells at will. This allows them to remove usual human limitations such as a finite lifespan, irreparable neural injuries, and susceptibility to disease. A new incoming regime and President in the United States however rescinds the “Human Decency Act” an action which would result in war with the Cygens. The story follows Roa a newly reborn Cygen and the events that spiral around her.
