OVA
Description
D/Sergei, often referred to simply as D, is a primary antagonist and a formidable operative working for the powerful and corrupt executive Jinsaku Ajo. His background suggests a past as a soldier or mercenary, having served under Ajo for a considerable period, during which he has been subjected to extensive physical modification. Sergei is not an ordinary human; he possesses superhuman strength and endurance as the direct result of artificial enhancement processes, which have transformed him into a highly effective instrument of violence.
Personality-wise, Sergei is ruthless, relentless, and deeply unstable. He carries out Ajo's special missions without hesitation, especially those requiring lethal force, and is known to be a cruel and menacing presence. A dark and defining aspect of his character is a dependency on a mysterious substance known as gel. This dependency leads to severe withdrawal symptoms, during which his mental state deteriorates dramatically, causing him to act in horrifying and irrational ways, such as an incident involving a corpse. This addiction and the psychological toll it takes on him paint a picture of a man who is as much a victim of Ajo's experiments as he is an agent of his will, trapped in a cycle of dependence and servitude.
Sergei's primary role in the story is to hunt the protagonist, Key, on behalf of Ajo's organization. He is the enforcer sent to capture or eliminate her, often deploying and combating PPOR (Psychological Power Operated Robot) units in the process. This mission brings him into direct and repeated conflict with Key's protector, Tomoyo Wakagi. Wakagi, who has a mysterious and opposing history likely also tied to military service, functions as Sergei's direct counterpart and is one of the few individuals capable of defeating him in combat. Sergei's relationship with his master, Ajo, is one of patently clear subservience; he is a tool used for dirty work, and his loyalty is born from a combination of fear, programming, and perhaps a desperate need for the gel that Ajo can provide.
Throughout the narrative, Sergei shows little to no positive development. He remains a persistent and threatening force, defined by his physical power and his tragic, debilitating addiction. His fate, like many others caught in Ajo's schemes, is tied to the downfall of the corrupt organization he serves, highlighting the ultimate powerlessness that plagues many characters in the series, where even the strongest enforcer is merely a disposable asset.
Notable abilities beyond his superhuman physique include expertise in operating PPOR robots and proficiency in various military tactics. Perhaps his most peculiar and surprising ability is his capacity to spit small, marble-like objects with enough force to cause serious injury, turning even his own saliva into a dangerous projectile. This bizarre skill, combined with his physical enhancements and addiction, makes him a uniquely unsettling and memorable adversary.
