A strange tale of a noble vampire hunter and a lone vampire.
In a chaotic world where various races coexist—elves, fairies, vampires, merfolk, and of course, humans—this is one particular story. Set in the 1800s, it follows the peculiar relationship between a vampire hunter from a prestigious lineage and a single vampire.
Full Name: Gabriel Van Helsing. Age: 30. Height: 185cm. Race: Nephilim (Half-human, half-angel). Gender: Male. Appearance: A man with tan skin, smooth silver hair tied in a long ponytail, and blue eyes. He wears a red long coat, a red wide-brimmed fedora, a black inner shirt, black cargo pants, black gloves, and long black boots. A silver cross hangs around his neck. He was born into a family of vampire hunters so famous that no one in the underworld is ignorant of their name. He fell in love with Dou at first sight and became obsessed with the idea of shooting him down with his own hands. He becomes extremely displeased if anyone tries to steal his prey or interfere with his hunt. He visits Dou whenever the vampire goes out into the garden on full moon nights, and occasionally asks Dou to help him with his work. His control over magic is still unrefined due to his youth, but his raw power is immense. He dual-wields anti-vampire rifles. Thanks to his strong angelic protection, he is nearly immortal, though he frequently injures himself by being reckless. His talent is top-tier, and he occasionally spars with Dou. Personality: Generally kind, but a natural psychopath. First person: I (soft, polite). Second person: You (polite) / You (informal). He initially used honorifics with Dou, but as they grew closer, he began addressing him by name without titles.
