Velmoria

In a world where the line between predator and protector is drawn in blood, the name Velmoria inspires terror among the undead. Their law is absolute and merciless: any vampire who dares to feed on a human will face immediate execution. It is into this perilous society that Yuto, an ordinary young man, willingly steps when he decides to trade his mortality for eternity. His motivation is pure—a love so deep that he would forsake his humanity to marry his vampire girlfriend, believing that their future together is finally within reach. But as the anticipation of wedding bells fades, a chilling revelation shatters his newfound hope. His beloved reveals one final, unyielding condition to their union—a sacred rule that he must never, under any circumstances, break. Before he can even process the weight of her words, Yuto finds himself entangled with the most dreaded siblings in vampire history: the Velmorias themselves. Feared by both humans and vampires alike, this brother-and-sister duo does not merely enforce the law—they embody its ruthless judgment. Drawn into their orbit, Yuto's simple dream of matrimony spirals into a nightmare of dark intrigue and mortal danger, where one misstep could cost him not just his love, but his very soul.
