Borma functions as Public Security Section 9's explosives and bomb disposal specialist. He rapidly develops cyberviral countermeasures against emerging digital threats. Physically, he possesses a bald head and distinctive cybernetic optics differing from other team members, alongside enhanced strength comparable to Batou's. During field missions, he frequently handles heavy weaponry and provides rear support.

His background includes prior service as a demolitions expert in the Japanese Self-Defense Forces (JSDF), suggesting potential special forces or combat engineering experience. Speculation exists that his cyberization occurred before any sexual experience, potentially contributing to susceptibility to the Individual Eleven virus during the refugee crisis events.

He typically partners with Saito for sniping duties, Pazu for general operations, and Ishikawa for cyberweb research. An avatar depicted him as a flat, round "0906" during the "Selecon" operation, suggesting a specific hierarchical position within Section 9's internal structure.

Later franchise installments such as *Solid State Society* or other official media beyond *Stand Alone Complex 2nd GIG* offer no substantial character development or expanded background. His military background coincides with the post-World War IV era but lacks specific chronological placement.
