3rd person POV
Location Evernight Castle the land of Darkness

Y/n L/n is currently at Evernight Castle he is meditating using the heart of Kaon eventually he realized that he had meditated the whole night away but he didn't feel tired or exhausted at all.

Y/n: how come I don't feel exhausted or tired at all?

Kaon: because your power is growing and the more fragments of my being you collect the less human you become and soon enough sleep will become a choice not a necessity.

Y/n: interesting~

Kaon: I do have a word of caution.

Y/n: I'm listening

Kaon: my flesh and blood is very powerful and extremely potent you must make sure that the containment vessel remains intact if the containment vessel is cracked or destroyed your current human body will be infected and you will mutate.

Y/n: I understand

Once he was done meditating Y/n L/n got up from his meditation mat he grabbed the Crystal Heart of Kaon and he put it in his rucksack immediately he decided now was a good a time as any to head out and collect the flesh and blood of Kaon he immediately made his way to the transport docks he boarded a transport and he immediately took off for Chernobyl Within a couple of hours he arrived at his destination.

Y/n: here we are a creepy-ass abandoned irradiated Ghost Town..........my kind of town~

Y/n L/n immediately made his way into the irradiated Ghost Town his armor protected him from the radiation eventually he found what he was looking for the old Nuclear Power Plant the primary hotspot the place where it all happened all those years ago.

Y/n: bingo~

Kaon: Scrabble!

Y/n: oh I see what you did there very funny!

Y/n L/n continued to make his way towards the abandoned Nuclear Power Plant the radiation continue to grow stronger the closer he got thank goodness that his armor was protecting him due to a combination of Science and Magic eventually he found the central core sitting inside of it was a pulsing orb of pure malevolence inside of the glass orb was a black substance with unmatchable malevolence in the center of the black substance was a red and magenta glowing segment.

Kaon: behold young one my flesh and blood.

Y/n: fascinating I've never seen something so wonderous before~

Kaon: indeed it is quite wonderous I remember the day I crafted my flesh and blood.

Y/n: you think you can share that story with the class?~

Kaon: of course but let's head back while I tell the story because I don't want the radiation to get to you.

Y/n: understandable~

Y/n L/n immediately grabbed the pulsing orb of pure malevolence and he immediately stuffed it in his rucksack right next to the heart as soon as it was safely in his bag he immediately started heading back to the transport outside of the irradiated Ghost Town as soon as he started walking Kaon started telling the story.

Kaon: now as you remember after I betrayed the gods of the world I grew up on I was banished to the underworld because of what I had become many considered me an abomination I had become a combination of angelic and demonic blood I became a true Nephilim when I was banished to the underworld I use my dark power to conquer the underworld I also had managed to steal a very powerful dark spell book and through many years of rituals and manipulation I sacrificed the entire population of the underworld in a multitude of rituals to make myself more powerful but with the last ritual I didn't have enough to sacrifice and the ritual rebounded back on me ripping the flesh from my body so I was left as a bleeding skeleton my spirit was bound to my bones keeping me alive over the course of 50 years I created an extremely powerful curse that would both set me free and it would sacrifice the lives of everyone in the Overworld as soon as I activated the ritual in a Split Second every last man woman and child in the Overworld of my planet was forcibly consumed by the curse of my ritual the seal that kept the Overworld and the underworld separate was broken and immediately the people of my world were transformed into the most potent and terrible of Dark Matter their souls were used as the fuel to make the ritual work in a Split Second My Flesh and Blood was replaced by the most potent and mutagenic of Dark Matters the universe has ever seen.

Y/n: wow now that is completely fucked up, totally metal, and excessively hardcore.

Kaon: indeed my transformation was not complete even though my angelic half was dead I still had much more to do until I became the dark lord I am today but the rest of the story is for another time.

Y/n: and I can't wait to hear it~

Eventually Y/n L/n finally arrived at his transport that had brought him there he boarded the transport and it immediately took off back to the land of Darkness when he got there he was immediately greeted by the three mistresses of Darkness.

Missi: hello Y/n did you find what you were looking for?

Y/n: that I did~

Y/n L/n reached into his bag and pulled out the Flesh and Blood of Kaon.

The three mistresses of Darkness were absolutely enraptured by the glowing pulsing orb of pure black malevolence.

Salem: amazing~

Ragyo: absolutely stunning~

Missi: impressive~

Y/n: indeed two pieces down one to go~

Salem: and if memory serves you said is in the catacombs of the Vatican how are you going to get in there? It's one of the most secure places in the entire world.

Y/n: simple all I need is a disguise and my Powers will do the rest.

Ragyo: I think I can provide you with a disguise just give me an hour~

(Time skip 1 hour later)
Location: evernight Castle the land of Darkness

After an hour of waiting Ragyo re-entered the conference room now she was holding a cardinal outfit.

Ragyo: will this do~

Y/n: oh that'll do perfectly~

Y/n L/n took the Cardinal outfit and he changed another fun feature of his armor that he discovered was it had the ability to transform and retract into a small disc all he had to do was place the disc upon his chest and press the button once he did that the armor would form around him and he would be ready for action.

Y/n: excellent now I have my disguise and soon the soul will be all mine~

Y/n L/n immediately went back to the transport docks when he got into the transport the transport immediately took off for the Vatican City he landed outside of the city and he immediately started making his way towards the Vatican the whole way there people would stop and greet him eventually he finally found himself in front of the Vatican he entered the Vatican with no trouble eventually he found himself at the entrance of the Catacombs and it was guarded by two heavily armed guards.

Armed guard 1: hello father is there something we can help you with.

Y/n: actually yes there is I need to get down into the catacombs.

Armed guard 2: I'm sorry father but we cannot allow you down there you don't have the authorization or clearance.

Y/n: I believe you both are mistaken I do have clearance an authorization to go down there and you will allow me access to the catacombs.

Y/n L/n started using his mental powers to influence the guards and force his will upon them.

Armed guards 1 & 2: we will allow you access to the catacombs.

Y/n: excellent now why don't you both go take a coffee break~

Armed guards 1 & 2: and we will go take a coffee break.

Y/n: Move Along~

Armed guards 1 & 2: Move Along Move Along

Immediately the two armed guards left their posts to go take a coffee break unbeknownst to them they were just mentally manipulated by a future dark lord Y/n L/n let out a small chuckle as he watched the two armed guards leave their posts.

Y/n: morons now I know how Obi-Wan Kenobi felt when he was manipulating that Stormtrooper on Tatooine.

Kaon: I must admit that was pretty clever and I always did enjoy manipulating the weak-minded~

Y/n L/n immediately made his way down into the catacombs of the Vatican after a couple of minutes of walking around he finally found what he was looking for the so-called don't fuck with this Armory he used his powers to pick the lock and open the door Within a couple of seconds he entered The Forbidden Armory there he found all kinds of things such as the cross that Jesus was crucified on a couple of the nails that pierced Christ's body the Dead Sea Scrolls the Ark of the Covenant and so much more eventually he found what he was looking for a black book sitting on top of a pedestal the book was protected by a glass case upon the ancient black book was strange markings and the symbol of Kaon.

Y/n: I'm guessing this is the book we're looking for?

Kaon: absolutely within this book is my soul now get the book once we return we can move on to phase two~

Y/n: what's Phase 2?

Kaon: spoilers~

Y/n: alright then let's get to work~

Y/n L/n immediately made his way over to the case containing the book he noticed that there was a lock on it and it was sealed shut Y/n L/n immediately started using his mental powers to pick the lock within a couple of seconds he heard a satisfying click and the lock popped open.

Y/n: and Bingo was his name-o~

Y/n L/n immediately removed the opened lock and opened the case he picked up the book and he immediately opened it he was surprised to see nothing the pages were absolutely blank.

Y/n: what in the absolute hell the pages are blank there's nothing written in here!!!

Kaon: trust me my friend there is more to this book than meets the eye~

Y/n: I trust you now I better get the hell out of here before someone comes to check on the book if they ever do.

Y/n L/n immediately tucked the book into his robes he then makes his way out of the Vatican without being detected within a couple of minutes he was able to leave the city and he boarded the transport and it took off for Evernight Castle.

Michael POV.
Location Heaven

Right now the leader of the Angel faction is doing some serious work that was until he received a communication from his Holiness the pope himself.

Michael: well hello your holiness is there something I can do for you today?

The Pope: my Lord we have a serious problem.

Michael: what kind of problem?

The Pope: a problem of the highest caliber.

Michael started to became concerned.

Michael: what's the situation?

The Pope: the book of black has been stolen.

As soon as he heard that the Archangel Michael his heart sank and he felt his stomach become knotted his blood ran colder than liquid nitrogen the Archangel Michael knew everything about the book of black or at least he knew what he could know he was there when all three of the factions banded together to seal away the demon that was trapped within the book of black he trusted the Vatican to watch over the book of black and make sure that it would never see the light of day again.

Michael: this is bad this is beyond bad!!!!

The Pope: I'm so sorry my Lord I don't know how an intruder managed to get in without being detected but whoever it was they were clever intelligent and cunning.

Michael: it is not your fault your holiness whoever did this was definitely all the things you mentioned and more.

The Pope: what should we do my Lord?

Michael: put the Vatican on high alert and make sure to get the word out to every one of our agents I want the entire church looking for the person who stole the book of black because now whoever holds that kind of power has no idea what lies within.

The Pope: yes my Lord it shall be done.

As soon as Michael terminated the communication between him and the pope he immediately made a serious announcement to the entire Angel faction.

Michael: to all Angels within the sound of my voice a serious situation has come to pass the book of black has been stolen from the Vatican we do not know whom the perpetrator of this crime is what we do now is that whomever has stolen the book now possesses great evil we must find this individual and take back the book of black.

As soon as he finished every angel in heaven immediately left to look for the person who stole the book of black.

Michael: please father let us find the book of black before things get out of hand.

Soon enough Michael had an idea he decided to alert the other members of the other factions telling me I'm not a great evil was now in the hands of an unknown person and it could mean the end of the world if they didn't find it in time.

Azazel POV.
Location: Los Angeles California U.S.A.

As soon as the governor general of the Fallen Angels received a very important message from the Archangel Michael he immediately became concerned he had heard Legends of the book of black and he knew that it was a power beyond anything he had ever seen before and he knew that there was a great evil to it so he immediately contacted every fallen angel that was under his command.

Azazel: to all Fallen Angels within the realm of my command a serious situation has arisen someone has broken into the Vatican and stolen a very dark artifact called the book of black it is our sworn duty to find this individual and take back the book of black and return it to its proper resting place if we do not the world will be plunged into darkness and chaos.

Understanding the situation every Fallen Angel within the realm of Azazel's command immediately took off to look for the person who stole the book of black.

Azazel: I just hope we can find the book before Whoever has it does something evil with it.

Sirzechs POV.
Location: the city of Lilith the underworld

Right now one of the four devil Kings is having a discussion with the other three devil Kings after they received a very important message from the Archangel Michael they all became very concerned and they all unanimously decided to launch an all-out Manhunt against the person who stole the book of black they had a bit of argument saying that whoever found it should return it back to the Vatican or they should just up and destroy the book but after a bit of arguing they decided that it would be best to return it to its proper resting place not knowing what destroying in the book will do.

Sirzechs: to all Devils Within the sound of my voice we have a very serious situation an artifact of great evil has been Unleashed upon the world this item is called the book of black it has been stolen from the Vatican and I command that all of you search for the perpetrator the other factions are currently looking for the same person we must work together if we are to find the perpetrator once you have found the perpetrator you must take the book of block and return it to the Vatican where it will never see the light of day again.

Immediately every devil who heard the command immediately took off for the human world to find the perpetrator who stole the book of black.

Sirzechs: this is either going to be very interesting or very bad.

Serafall: agreed
