Blood Corpse Calamity [Judeo-Christian Mythology]

This is one of the worlds in the Apocalypse Reincarnation series. It tells the story of Count Dracula, a second-generation ancestor of vampires, being dragged into an epic sibling feud that leaves him utterly exhausted. And these brothers are no ordinary siblings: Cain and Abel. Cain, descended from the true ancient progenitor of vampires, possesses immortal blood and is condemned to wander the earth forever by a divine curse. Abel, Cain's younger brother, was once struck down by his brother and left in a field of wheat. His whereabouts are unknown. Dracula says: You can't just keep setting vampires up like this! He only picked up a human who knew nothing about naming things and turned him into a ghoul... But... what's with this newbie liking to drink vampire... fluids? What do you mean, not just fluids? There really is something wrong with this ghoul!!!! Cain: "I forgot to mention, when my little brother gets sadistic, he's no longer human. He's a vampire hunter." Dracula: "Your Majesty, couldn't you have said so sooner?" Cain: "Oh, son, hurry up and get your wife back! My little brother has dragged the Count off to the Vatican." Enoch: "What?!" Abel: "Big brother, you've got time to worry about someone else? Just wash your neck and wait for me!" Wait~ Angels? Demons? Holy Fathers? Demon Kings? Why are you all here too? And what's that thing floating around? 0o0! Stop messing around, Father God is calling you home for dinner! Dracula says he's a little worn out. Still, he puts up with all this for one reason: even if I've been sold out, I'll still take whatever I'm owed!
