The Eternal Night Disk

After the vampires were defeated, Calain, the child of a vampire and a human, fled to a human kingdom. He wields the vampire holy sword Blood Moon Oathbound Abyss. His left eye is as crimson as the night, his right as black as the abyss, and two opposing powers flow through his body. In a world where the sun has been restored by the gods and cracks in the abyss are stirring, he will uncover the truth of his bloodline: is it a curse, or the key to salvation?
