D is the offspring of a human mother and a legendary Vampire lord who is also known as the father of all vampires. He has inherited the skills and grace of both races, but he faces discrimination due to his mixed lineage. Despite this, D possesses surprising power and resourcefulness, with most of the strengths of vampires and only mild levels of their weaknesses. Unlike other dhampirs, D can live as a human without being marked by an unearthly beauty or powerful aura. However, he is emotionally remote but sometimes sentimental, and once every five years, he experiences sun-sickness, which is a severe form of sunstroke. Otherwise, D does not suffer from the usual weaknesses of dhampirs, boasting an imposing supernatural aura to his opponents and godlike reflexes that surpass even those of vampires.
