The World called me an abomination, a freak of nature, a stain from my mother's legs.

Even after righting their wrongs with my blade, it was still the same.

However, in the midst of my despair, one person reached out his warm hand for me.

Lucifer Morningstar. Even though he is the Devil spoken of in Legends, I shall take the leap of faith and do his bidding.

To take breath in reincarnation in another world and Slaughter my foes: Demons, Angels, Devils, gods, and everything I consider EVIL in my PATH

Don't get me wrong, my blade is a respecter of neither man nor beast. 

All that stand in my way shall FALL to the recreation of a world in the image I see fit.

............
If you want to know how sick this book is, read the first chapter.
I still don't know how the idea for this book came out of my head.
(Heaven! please forgive me)
.....



Demons, Devils, Fallen Angels, Angels, Soul Eaters, Cursers, Witches, Dark elves, Hell beasts, Heaven Beasts, Death Beasts... 

Practically, Every sick, both rosy and terrible thing of the underworld will be found in this book.

My research is deep.

(Note: Sick Shit happens here. If you don't have stomach for it, please run. You still have time.)

Devil Slave (Satan system)

This was a really burly demon, and was a bit of a hassle to tear into his chest, but Lenny had some how entered the zone. The process just came naturally to him.

Even without his memories, it felt like this was what he was supposed to do, and so he gently and tenderly opened into the chest.

If any of the surgeons in his former world were to see his job, they would be moved to tears. It was absolutely beautiful to behold. Every fiber of every muscle cut in such perfection that not even a drop of blood had leaked from the wound he had opened up.

Deeper, he went, layer by layer, until he reached the heart hiding behind the lungs.

With Lenny's continuous killing and experimentation of demons, he had come to understand that their hearts were very unique, and changed according to the Demon rank, the bloodline of the Demon, whether they were royalty or not, and the kind of bloodline technique that it had inherited.
