Jedda Hassan, a surviving researcher from the Borgman Project—a classified initiative advancing cyborg development—is recruited by the Tokyo Police following the original series’ events to investigate emerging cyborgs tied to the covert Heaven’s Gate project. His mission intersects with Ryo Hibiki’s journey to Japan, where Ryo seeks reconciliation with Anise Farm, a fellow Borgman.

Tasked with tracing unauthorized cyborg operations, Jedda joins Ryo, partnering with law enforcement and Borgman allies to dismantle the threat. His specialized knowledge of Borgman technology proves indispensable in dissecting Heaven’s Gate’s capabilities, though his precise technical methodologies remain undisclosed. The collaboration underscores his role as a pivotal liaison between investigative efforts and the Borgman Project’s legacy, with his actions confined strictly to the OVA’s documented events.
