Borma operates as Public Security Section 9’s tactical explosives and cyberviral warfare expert, wielding heavy weaponry during missions while delivering critical rear support. His rapid-response proficiency in neutralizing digital threats allows him to engineer cybervirus countermeasures—often crafting vaccines within minutes of exposure. Before joining Section 9, he refined his expertise as a demolitions specialist in the Japanese Self-Defense Forces, with unconfirmed reports hinting at clandestine roles in special operations or combat engineering.

His bald head and uniquely tinted cybernetic optics distinguish him visually from teammates. A past encounter with the Individual Eleven virus—which exclusively targeted non-cyberized individuals—subtly implies his full-body cyberization occurred prior to sexual experience.

On missions, he routinely collaborates with Saito for precision sniper coverage, Paz for frontline assignments, and Ishikawa during cyberweb analysis. Virtual operations reveal his team hierarchy through minimalist identifiers, such as the numerical "0906" avatar employed during digital investigations.

In *SAC_2045*, Borma rejoins Section 9 amid escalating post-human crises, though his early contributions remain limited to strategic support. Archival discrepancies occasionally render his name as "Boma," aligning with the silent "r" in its original pronunciation.
