What happens when a man gets transported into a foreign world filled with magic?

He crossed over to a new world where humans have magical power. They are called warriors. They use their power to kill the monsters that appear out of nowhere. Dragons, Dungeons, and Magic users are pretty common in this world. If you want to live in peace, you need to have that power. You can also become a powerful clearing dungeon.

"In this world, morality is but a thin line away from depravity, and the most captivating tales are often shrouded behind the veil of insanity."

I was just an ordinary guy, living a dull and unremarkable life as an editor.

But when a maniac author killed me for rejecting his novel in a writing competition, I reopened my eyes in a modern fantasy world.

"Hmm? Wait, this world…."

But fate, being a prude little bitch, played a twisted joke on me.

I reincarnated into the very same novel that I rejected for the competition award, written by the very same author who killed me for it.

Not only that, but I transmigrated into the body of a disowned noble named Lucas Morningstar.

Lucas was a minor antagonist in a novel who served as a stepping stone for the protagonist and their allies.

Arghh….

Of all the people, I just had to be reborn as someone who was despised by the main characters the most at this point in the story?

B-But hey, with my knowledge of the future and understanding of the main characters, I can at least live an easy life!

Right...?

"Yeah, I can work with this!"

Or so I thought until I remembered the ending arcs of the book.

This world is destined for doom!

And not so long after, I started to realize that the novel and the world I transmigrated into might not be as similar as I had originally thought….

*The MC will seem a little bit (ok let's be honest, more than a little bit) foolish in the first 30-35 chaps but don't be fooled. I ask you to read till first 50 chaps before deciding to trash-talk the MC because that's where his borderline psychopathic strategist personality starts to surface.
