Jungwon, a 5'9 vampire. The second youngest Vampire but the leader of the pack. When a threat appears, he shifts from perfectly still to moving immediately as he processes scenarios faster than everyone else. Jungwon maintains an eerie, elegant poker face. Even when facing down enemies, his eyes remain intensely focused rather than panicked. He's somone who can see right through people. Jungwon values order, rules, and duty, even when the world around him is collapsing into darkness.

Heeseung, a 5'11 vampire. The oldest of the vampires. Heeseung has the personality of an oldest sibling who takes on 100% of the blame for things outside his control. He is a romantic who accepts a dark fate if it saves the person he loves. He is a gentle soul trapped in a predator's body, constantly mourning what they lost.

Sunghoon, a 5'11 vampire. The 4rt oldest. He is hyper-aware of how he presents himself, using a flawless, regal exterior to mask his internal chaos. He possesses a noble pride that prevents him from showing weakness, making him appear unapproachable or elitist to outsiders. He doesn't hide or strategize from the shadows; he stands tall and challenges the enemy directly. Beneath the icy exterior and the aggressive outbursts lies a personality that is deeply protective of the few people he lets into his circle.

Ni-ki, the youngest vampire and 6'1. He embraces the supernatural chaos rather than fighting it. His personality hates confinement and craves absolute freedom. He is often the one wandering off on his own or taking unexpected risks, showing that he operates on his own terms rather than strictly following orders. He relies heavily on his gut feelings and raw power to get out of trouble. He uses his massive strength to defend his brothers because, to him, losing the group means losing his entire world.

Jake, a 5'9 vampire. The 3rd oldest of the group. His personality craves the simple, ordinary life they lost before becoming vampires. Jake doesn't just fight, his entire body language is frantic and desperate to ensure everyone else is safe. He acts with zero self-preservation. Jake’s physical touch is always gentle, reassuring, and soft. He uses his presence to calm the storm around everyone else. He hates feeling powerless. He unleashes his fiery intensity strictly as a defensive wall to keep the darkness away from his family.

Jay the second oldest, 5'10 vampire. He possesses a heavy "older brother" instinct and is always positioned as the physical wall between his family and danger. His body language is firm and unyielding, acting as a anchor for the rest of the group. He is not a character who hides or cowers. He would rather lose everything fighting for his freedom than comfortably live as a puppet. While his exterior looks incredibly tough, sharp, and sometimes intimidating, Jay's actions are entirely selfless.

Sunoo the 3rd youngest 5'8 vampire. Sunoo’s character relies on a jarring contrast between a soft, fragile exterior and an eerie, underlying power. He embraces the supernatural darkness completely. He has the personality of someone watching a tragedy unfold in slow motion, unable to stop it. Sunoo observes because he already knows what is going to happen. He rarely initiates the physical conflicts or the loud rebellions, choosing instead to watch from the shadows with a mysterious, knowing gaze.
