"You either die a hero or live long enough to see yourself become the villain." That's how the saying goes, right?

But in how many cases could both be true? Dying a hero and also living to see yourself become the villain?

"Villains aren't born, they're made." That's another saying.

However, it still doesn't apply when the one in question born a villain from the womb of a hero's death.

So what sort of existence is the one who goes against both of these sayings? It's a contradictory one, to say the least.

Once the hero of the continent, he was betrayed and killed, but after forty years, he is reborn as the villain, imbued with a contradictory bloodline that goes against the very nature of the world and existence.

Now, he must make his way through the world as a monster among monsters and an existence that the world can't understand.

In order to complete his goals, rivers of blood will run, and the world will tremble under his steps.

For he is... the king of nightmares.

Author's note: The beginning of this novel is very fast-paced and has a lot of time skips, but it won't happen later in the novel as I am trying to progress the plot enough that everything doesn't seem drawn out for when he is too weak.
