Borma operates as the explosives and cyber-viral warfare expert in Major Motoko Kusanagi's special operations unit. He rapidly develops counter-viral vaccines and handles heavy weaponry during missions, frequently providing rear support while working alongside sniping specialist Saito, general operations agent Pazu, and cyberweb researcher Ishikawa.

His background includes service as a demolitions expert within the Japanese Self-Defense Force, suggesting prior roles as either a combat engineer or special forces operative. Borma possesses enhanced physical strength comparable to teammate Batou, distinctive optical enhancements, and a bald head. His position is marked by the avatar designation 0906.

Fully cyberized, Borma remains vulnerable to ghost-hacking viruses like Fire-Starter, requiring maintenance resources common to full cyborgs. The silent "r" in his name leads to the alternate transliteration "Boma."

During *The New Movie* events, Borma participates in operations against the Fire-Starter virus outbreak and the Prime Minister assassination. He engages in combat sequences such as a dock battle where he deploys heavy weapons against mechanical opponents. His role remains consistent with prior *Arise* series portrayals, focusing on technical support without significant evolution.
