BD serves as a high-ranking military officer spearheading covert operations to reclaim a stolen experimental motorcycle possessing advanced capabilities. Upon identifying the protagonist’s connection to the prototype, BD mobilizes aggressive pursuit teams, suppresses public knowledge of the vehicle, and escalates hostilities by staging a coup—eliminating superiors to seize government control. This power grab aims to harness the city’s central AI system against the Dezalg, a rival faction perceived as an existential threat.

Driven by survivalist pragmatism, BD enforces authoritarian policies to consolidate domestic control while diverting military assets to orbital warfare. Prolonged conflict depletes resources, destabilizes systems, and triggers an autonomous lunar defense protocol that threatens both factions with annihilation. Forced to adapt, BD pivots tactics, prioritizing civilian evacuations as the conflict nears its catastrophic end.

A key confrontation unfolds when BD encounters the protagonist, whom they previously framed for murder. During this exchange, BD concedes mutual vulnerability to uncontrollable forces, then engineers a sacrificial strike to draw enemy fire away from evacuation routes. Later historical records omit definitive accounts of BD’s fate, though peripheral archives ambiguously imply potential escape via departing ships.

BD’s trajectory evolves from ruthless militarism to reluctant compromise, treating the protagonist first as a hindrance, then as an inadvertent ally in safeguarding survivors. Decisions prioritize immediate survival over morality, blending ideological resolve with last-ditch adaptability as collapse becomes inevitable.
