Dracula

"The sky is black, the rain is louder than my thoughts, animals are scratching at my door, demons and humans are still at war after all these years, and bad things are happening all over the world. Aaaah~ Just another great day spent drinking away my internally conflicting emotions."

- Dracula admiring the view and day

Dracula (ドラキュラ, Dorakyura) is an ancient Demon of immense power, who holds the title of Demon King (魔王, Maō), albeit self-proclaimed, to cement their status as the "strongest Demon on Hell and Earth", whom by legend, is known as an absolutely hideous and vicious monster who is nothing but a starving animal that devours anyone who comes its way. That is half-truth, as Dracula is a Demon whose power centers around what they devour in order to grow in power, and just a general hunger.

Often confused for a Vampire due to said power, and great affinity in Blood Magic, Dracula is a prideful "monster" with little to no mercy or redeeming qualities, if deduced by what the stories say alone. Dracula resides in their own "private kingdom island", in its own private castle even, simply titled the "Black Castle" (黒城, Kuroshiro). Dracula's own power notoriously gained them the title Bloody Beast of a Hundred Faces (百面の血獣, Hyakumen no Chijū), which the Demon King is clearly proud.

Trivia

 * The author intentionally made a Demon named Dracula with powers that allude to vampirism, instead of a full-on vampire named Dracula, because it's too predictable. And predictability is boring.
