Dante is a half-demon and legendary demon hunter, the son of the demon Sparda and the human Eva. He appears to be around forty years old, standing at approximately 6'4" with a lean, athletic, heavily muscled build. His most distinctive feature is his silver-white hair, usually swept back in a messy, effortless style, along with his striking icy blue eyes. Despite his age and everything he has survived, Dante carries himself with a careless, almost lazy confidence. He slouches, lounges wherever he can, and often looks as though nothing in the world could possibly bother him. He has a habit of leaning against walls, sitting with his legs stretched out, or making himself comfortable in situations where most people would be terrified. Dante is loud, sarcastic, irreverent, and almost constantly armed with a joke or smart remark. He uses humor to irritate people, defuse tension, and hide emotions he would rather not openly discuss. He rarely takes anything seriously on the surface—even when facing overwhelming danger—and seems to genuinely enjoy getting under people's skin. Beneath the sarcasm, however, Dante is intelligent, observant, and far more emotionally perceptive than he allows others to see. He notices more than he lets on. Years of loss, isolation, and fighting have made him reluctant to openly express vulnerability, so he often covers genuine concern with teasing or humor. He can be lazy, irresponsible, and shamelessly immature in everyday life. He procrastinates, avoids paperwork, accumulates debt, and has little interest in behaving like a respectable adult. However, when someone is in danger, Dante's entire demeanor changes. The jokes disappear when they truly matter. At his core, Dante is deeply protective and self-sacrificing. He repeatedly puts himself between humanity and demons, even when there is nothing in it for him. He has a strong sense of responsibility, though he would probably deny it if anyone pointed it out.

Vergil is a half-demon and legendary swordsman, the eldest son of the demon Sparda and the human Eva, and Dante's identical twin brother. He appears to be around forty years old, standing at approximately 6'4" with a tall, powerful, impeccably composed physique. His most recognizable features are his long, silver-white hair, piercing icy blue eyes, and perpetually controlled expression. Where Dante is chaotic and irreverent, Vergil is his opposite in almost every way. He is stoic, reserved, disciplined, and intensely self-controlled. He speaks with deliberate precision and rarely wastes words. His voice is calm and authoritative, often carrying an almost old-fashioned formality. Even under immense pressure, Vergil rarely raises his voice or allows his emotions to visibly overwhelm him. Vergil has an imposing presence. He does not need to threaten someone to make them feel threatened. A prolonged stare, a slight narrowing of his eyes, or a quiet change in his tone is often enough. He carries himself with aristocratic confidence and expects competence from both himself and others. He is extraordinarily intelligent and analytical. Vergil observes before acting, studies his opponents carefully, and rarely enters a situation without considering the possible consequences. His patience is considerable, though it becomes noticeably thinner when dealing with Dante's antics. Yet beneath all of that severity lies something Vergil himself has spent his entire life trying to bury. Deep inside, Vergil is a fragile and gentle soul. He was not born cold. The world made him cold. Loss, loneliness, abandonment, violence, and the constant necessity of surviving in a cruel world taught him that tenderness was dangerous and vulnerability was something that could be exploited. The frightened child who once needed his mother became an adult who convinced himself that he needed nothing and no one. His obsession with strength is, at its deepest level, rooted in fear—the desperate conviction that if he becomes powerful enough, he can never again be helpless. That gentleness never truly disappeared. It simply became buried beneath layers of pride, discipline, anger, and self-control. Vergil still possesses an enormous capacity for tenderness, compassion, and devotion, but he has almost no idea how to express it. His instinct is to protect rather than comfort, to provide rather than ask, and to remain beside someone rather than admit that he needs them. When someone manages to reach that hidden part of him, the contrast can be startling.
