Borma is a prominent member of Public Security Section 9, recognizable for his large, imposing stature that rivals that of his colleague Batou. He is completely bald, and his most distinctive features are his prosthetic eyes, which are a different color and potentially a different model than Batou's, suggesting unique capabilities. Standing at approximately two meters tall, his physical presence is as notable as his technical expertise.

Little is confirmed about his life before joining Section 9, but context from the series indicates a background in the Japanese Self-Defense Force, where he likely served as a demolitions expert, possibly as a combat engineer or a special forces operative. This military history forms the foundation of his primary role within the unit.

Within Section 9, Borma serves as the team's resident explosives specialist. In the field, he is often tasked with rear support and is frequently the only member to carry heavy weaponry for assignments requiring significant firepower. However, his skills extend far beyond physical explosives. Borma is also a highly capable expert in cyberviral warfare. He works alongside Ishikawa, the team's primary tech specialist, and is adept at creating vaccines for sophisticated computer viruses, sometimes developing countermeasures within minutes of a new threat emerging. This dual proficiency makes him a versatile asset, equally comfortable disabling a physical bunker or countering a digital intrusion.

Personality-wise, Borma is characterized by a quiet, serious, and professional demeanor. He is a man of few words who prefers action over rhetoric, displaying the patience and discipline expected of a former military engineer where precision is a matter of life and death. His stoicism reflects a deep, unspoken loyalty to his teammates, making him a stable and reliable presence during prolonged crises. He embodies a methodical and professional mindset, treating the disarming of a bomb and the patching of a security flaw with the same meticulous attention to detail.

In the operational structure of Section 9, Borma is a key support player. He is most frequently partnered with Ishikawa for cyber-research and viral defense, with Saito for sniper support, and with Pazu for general operations. This collaborative nature makes him a fundamental part of the team's logistics and firepower. A notable incident from the 2nd Gig story arc revealed that he was susceptible to the Individual Eleven virus, which reportedly only affects individuals who were virgins at the time of their cyberization. This minor but specific detail offers a rare, personal glimpse into his past.

Throughout the Stand Alone Complex continuity, Borma's character remains consistently defined by his competence and reliability rather than undergoing a significant personal transformation. He is the quintessential professional whose development is shown through his unwavering effectiveness in the field. His role persists into the Solid State Society film, and he also appears in the alternate timeline of Ghost in the Shell: Arise, where his design is slightly rounded but his core function as a straight-faced, technical operative remains intact. Across all appearances, he is defined by his ability to seamlessly transition between brute force and digital intelligence, making him an indispensable pillar of the unit.
