But when a chance encounter with a vampire attack leaves him at death’s door, he wakes up to a new reality—he's no longer human.Now a ghoul, the lowest rank of undead, Masaru finds himself thrown into a world of ancient bloodlines, deadly supernatural creatures, and secret organizations hunting beings like him. His only guide? Akane Mikazuki, the cold and ruthless noble vampire who saved him, but only for her own mysterious reasons.Armed with the Cape of Dracula, an artifact of legendary power, and an unnatural potential that defies vampire logic, Masaru refuses to accept his fate as a weakling. If the world wants to treat him like a mere undead—then he’ll rise above them all and prove them wrong.As battles erupt between vampires, werewolves, assassins, and monstrous beings, Masaru must claw his way up the supernatural hierarchy before he’s devoured by forces beyond his comprehension. Because in this world, the weak exist only to be devoured.But what happens… when an undead refuses to stay at the bottom?

All humans transmigrated to a parallel world, where every one of them was a king with the territory.

They participated in a game called The Ranking of Kings and fought to become the best nation.

The rankings were determined based on various aspects such as military, technology, commerce, culture, and religion.

In the game, the kings would awaken different attributes of the land.

Someone exclaimed, “My Renewable Resources attribute allows me to enhance raw materials such as timber and minerals. I want to build the strongest empire of commerce!”

Another king challenged, “My King of the Undead attribute allows me to summon dead souls to fight for me. Who dares to stand in the way of my troops of one million undead?”

The third king declared, “My Integrated Production attribute will ensure that technology is being implemented efficiently. You foolish barbarians, watch as my nation advances a few centuries ahead of yours.”

The fourth king said, “My Miracle Summon attribute can increase the efficiency of evangelism by 1000%. I look forward to the day when my nation becomes the top religion in the world.”
