OVA
Description
BD is a high-ranking military officer serving within the shadowy forces controlling simulated Tokyo. After acquiring the prototype Garland motorcycle leads to his friend's death, BD relentlessly pursues protagonist Shogo Yahagi to recover the advanced technology and suppress exposure of the city's true nature: the space-faring colony ship Megazone 23.

Commanding agents who function as men in black, BD operates with considerable authority, using ruthless methods including framing Shogo for the murder of Tomomi Murashita after her film reveals the Garland. Following Shogo's temporary defeat, BD orchestrates a military coup, eliminating superiors to seize control as the city's de facto leader. His primary motivation is accessing the Bahamut civic computer and its AI, Eve, to mobilize Megazone 23's full military against the Dezalg, an advanced human threat from a rival colony ship closing in.

As commander-in-chief governing Tokyo in Part II, BD faces significant challenges maintaining control amidst the escalating Dezalg conflict and internal strife. His regime struggles with dystopian governance realities, hopeless warfare, and betrayal from former allies. Despite extreme methods and a personal vendetta against Shogo, BD acts as a well-intentioned extremist, genuinely believing his harsh actions are necessary for humanity's survival against the Dezalg.

His arc concludes during the climactic Dezalg assault and activation of the lunar defense system A.D.A.M., which begins destroying both Megazone 23 and the Dezalg. Recognizing impending doom and his plans' failure, BD shifts priorities: ordering military forces to focus on civilian evacuation, making peace with Shogo, and sacrificing himself in a suicidal charge against the enemy. This final act aims to buy time for Shogo, Eve, and civilians to escape via the Bahamut core towards Earth. His storyline is confined to Parts I and II, with no direct involvement in Part III.
