Houketsu no Ronnie

The tranquil existence of a young boy named Ronnie is shattered when a brutal assault reduces his village to cinders and claims the lives of his parents. Dragged to the towering, foreboding fortress of the legendary vampire lord Dracula, Ronnie is thrust into a world of perpetual shadow and ancient malice. Surrounded by the very monsters he has come to despise, he clings to a single, burning purpose: avenging his family by destroying the immortal fiend who orchestrated their demise. Yet, within those cold stone walls, survival seems an ever-dwindling hope against a predator of immeasurable power. Ronnie’s grim trajectory takes a startling detour when the vampires uncover a secret hidden within his very bloodstream. He possesses the fabled "Blood of the Full Moon," a substance of extraordinary rarity that ignites a fierce, covetous hunger among the denizens of the castle. In an instant, he is transformed from a helpless captive into the epicenter of a dangerous obsession. Every shadow conceals a new threat, and every ally is a potential betrayer as ancient bloodsuckers scheme to claim him for their own purposes. Now, Ronnie must walk a razor's edge, navigating a pit of political intrigue and primal greed where his life is the ultimate prize—and his quest for revenge grows increasingly entangled with the desperate will to simply survive another night.
