Borma operates as Public Security Section 9’s explosives specialist and cyberviral warfare strategist, managing heavy weaponry, tactical rear support, and rapid development of cybervirus countermeasures. His ability to engineer vaccines swiftly after exposure to emerging threats underscores his technical precision. He collaborates closely with Saito during sniping operations, partners with Pazu in field missions, and assists Ishikawa in cyberweb analysis and viral defense protocols.

Before Section 9, his tenure in the Japanese Self-Defense Force focused on demolitions, indicating a potential history as a combat engineer or special operations specialist. Physically, he mirrors Batou in height and augmented strength but possesses unique cybernetic ocular systems. Baldness and distinctive ocular enhancements define his appearance.

In *Selecon*, his team identifier manifests as a flat, circular avatar marked "0906," reflecting his rank hierarchy. In-series dialogue implies his cyberization occurred prior to sexual experience, a speculated vulnerability factor during his exposure to the Individual Eleven virus.

Borma reappears in *Solid State Society* as part of Section 9’s restructured unit, maintaining his core role in explosives and cyberthreat mitigation. The manga *Human-Error Processor* briefly features him at Niihama International Airport alongside teammates, with subtle variations in demeanor compared to anime portrayals. His origins and personal evolution remain undisclosed across all documented media.
