A/N: First of all, I like to thank you everyone who reviewed my story and is still around to it. Also, DemonKittyAngel, I appreciate you told me all those facts but like I said I don't write to get popular, I want people to readmy story. If you see Overlord crossover archive, the most popular doesn't even have Ainz as the main character. The popular ones who has Ainz as MC have like 30+ chapters and were few reviews while others without Ainz have like 10+ chapters with 1k+ reviews. No diss against those writers but I want to challenge that. I want to write a fanfiction with Ainz as MC being the most read and popular fanfic in Overlord crossover!

Secondly, I recommend everyone to read and review these awesome Overlord crossover.

CHAPTER 10: BEGINNING OF AN END

-KHAOS BRIGADE'S HIDEOUT-

Ophis was sitting quietly on a comfy sofa while waiting for Cao Cao and Rizevim Livan Lucifer. Rizevim was supposed to be the secret member of Khaos Brigade but considering the current situation, they had no choice but to bring him out in the light.

"I told you that I don't know!"

"What do you mean you don't know?! You are supposed to be the leader and yet you seems the most oblivious!"

The Dragon God heard two people arguing outside. The sound of footsteps drew closer and closer yet the arguing still continues. As the door opened, Cao Cao and Rizevim entered the room. Both of them still annoyed with each other but seemed to stop their argument in front of Ophis.

Ophis knew they don't get along with each other due to different ideals they uphold. But that didn't matter to her. It didn't relate to her goal in any way.

"So why did you call me here?" asked Ophis.

"As you know by now, the Khaos Brigade has lost a lot of its valuable members including Georg and Kuroka. There are quite a lot potential traitors still present in the organization." told Cao Cao.

"I see. If we start losing our people, then my goal to defeat that stupid dragon might not be achievable." said Ophis to which both Cao and Rizevim nodded, "What about your grandson, Rizevim? Is he still a trusted member of our group?"

To this, Rizevim simply smiled and shook him head on a 'no'

"That brat is unruly and unreasonable, honestly. We have lost contact with him a few days back. Though he was spotted in Underworld, it would seem he doesn't want to be a part of Khaos Brigade anymore." told Rizevim.

Another important member out of the group. That wasn't good. They were seriously losing firepower. At this rate, Khaos Brigade would be dissolved soon.

Honestly, she didn't care much about Khaos Brigade at all. What matters her the most to kick out Great Red out of Dimensional Gap. But she required more power for that. Thus, the Brigade was necessary.

"In addition to our problems, there is a rumor about a tomb has appeared outside Kuoh City. An unknown group has also appeared around that time. We were suspicious that they might be involved in the disappearances but..."

"But?" asked Ophis curious.

"Any attempt to find about anything about these group or the tomb proved futile. We searched the entire forest but got nothing. Also, most of the claims were based on rumors. So, we stopped the investigation." replied Cao Cao.

Now that he mentioned it. She did felt an odd presence in human world few months back. It was undetectable even to most skilled people but she was able to sense it nonetheless. At first, she dismissed as something inconsequential and of no importance but now the rumors begin, maybe it was linked to the disappearances.

"The three factions are still at each other's throats for the time being. If there is any time to take advantage of it and start a war, I'd say it is now." proposed Rizevim.

"Normally, I don't agree with Rizevim but this time I agree with him. We should act before we lose any more members and before it's too late." said Cao Cao.

A war among Three Factions? She wasn't a huge fan of fighting but whatever helps to push her cause.

"So it is decided then. We will wage the war. I will offer my power to every members who is capable enough to handle it. You guys go ahead and prepare the plans." told Ophis before she sat up to leave.

"And where are you going if you don't mind me asking?" said Rizevim.

"Outside of Kuoh to see if the rumors are true." told Ophis as teleported away.

-OUTSIDE OF KOUH-

It didn't take much time for Ophis to find out the tomb the rumors were talking about. She was very surprised that she found it so easily.

It was quite easy. Really way too easy.

Wasn't it supposed to be very well hidden to the point even the Khaos Brigade weren't able to find it? Something was definitely off.

Despite that, the Dragon God walked towards the door and entered the tomb.

The entire tomb was empty besides some undead skeleton which were literally blown away by her charging up alone. Feeling that the tomb was nothing but a waste of time she decided to leave.

That was until she felt something from below. It was a faint energy but it was something nonetheless.

Then she saw a trap door opening in front of her leading downwards. Taking the path downwards, she noticed that the room she entered was huge. To call it a room would be insulting, it was a huge floor but like the floor above it was empty too.

She saw abother trap door open and took it. Yet another huge but empty floor with entirely different landscape and another opened trap door

This series continued for quite some time until she finally reached a huge door. The source of the energy was just behind these doors.

Ophis was quite surprised to see how big the place really was. If she were to put all the floor together, the surface area would be equal to a large island or a small country.

Who would be the master of such a bizarre yet interesting place?

Letting her curiosity get the best of her, she opened the huge door. As she entered, her eyes widened in surprise by what she saw.

It was a throne room full of creatures she never saw in her life. All of them bowing before the one sitting on the throne. It was an undead sitting on the throne.

No. To call him an mere undead would be insulting given how much respect was shown to him.

The energy she was sensing from him was easily on par with top tier Gods. Yet the sinking feeling she was getting from him was as if she was looking at Death itself.

It was vile, horrifying and even awe-inspiring.

It wasn't just him. Judging from their power, even his subordinates standing besides him were terrifyingly as strong as him.

It was clearly an intentional display of power. They had gathered all the strongest members in the hall just for her. She wasn't sure why exactly they did that.

Was it a trap to attack her? Was it to warn her that she will be killed upon any hostility?

"Welcome, Infinite Dragon God. I hope you liked my home." said the undead.

So this is his home. That means he is the owner and she is the guest. Hence the greeting are very important. She will not lower her standards to that stupid Great Red and acts like she owns the place.

"It is quite impressive. Really big and different. Though, I don't know who you are?" said Ophis bowing her head.

"My name is Ainz Ooal Gown, ruler of this Great Tomb of Nazarick." told the undead.

"I have to ask, Ainz. I-"

"YOU LITTLE RASCAL! HOW DARE YOU ADDRESS AINZ-SAMA LIKE THAT!?" yelled the woman with black wings on her waist.

A huge wave of energy flowed through the entire hall. It wasn't just her. Everyone in the hall were just as angered as her. The mood turned grim immediately, as though a fog of bone-chilling cold hung in the air.

Ophis could feel goosebumps breaking out on her. This situation had just turned really bad for her.

"Are you seriously trying to challenge me? You think someone of your level is enough to beat me?" asked Ophis as she prepared herself for the battle.

"Tell me, God of Dragons. Do you truly believe that you can survive a direct battle against all us?" asked the demon wearing glasses.

As much as it hurt her pride, she had to admit he was right. One-on-one, she could defeat anyone in this hall but if they attacked her together, she doubt she could survive the battle.

"Enough!"

With one command from Ainz, the murderous intent disappeared instantly as if it never existed.

"Forgive my subordinates. They can sometimes act on their emotions alone. I guess titles and position of power are meaningless to a Dragon God like you" said Ainz.

She was surprised to hear him apologize. Someone who himself holds so much power and commands such an monsterous army was such a rational thinker. If it was someone else, she would already be fighting for her dear life or tried to escape.

"It's alright. It was rude of me to address someone who holds so much power and control so lightly. While I still hold my pride above most thing, I hope you don't mind me calling you 'Ainz-dono'" said Ophis.

"If that's how you wish to address me, then so be it." said Ainz much to his subordinates' surprise.

"The reason I came here was because many members of my organization have gone missing. Funny thing is they start to went missing around the time your tomb appeared here." told Ophis.

"Are you accusing me?" said Ainz.

"Of course." replied Ophis in an instant, "So was it you guys who did it?"

"Yes, you are right about that."

"Why did you do it, Ainz-dono?"

"While we needed them for experiments to see if the results prove more beneficial than human experiments, the real reason we kidnapped them was to get your attention." told Ainz.

"So that explains why they were not guards in the entire tomb. You were expecting me" said Ophis to which Ainz nodded.

"Alright then, you have my attention. So why exactly do you need me here?" asked Ophis curiously.

"I want you to leave Khaos Brigade and join forces with me instead." replied Ainz.

"Why should I do that? Those guys are serving me just fine." said Ophis

"Yes, that might be true. However, you have already sensed our powers. While there are strong members in your organization, from what my subordinates told me they aren't really as powerful as Nazarick forces. Isn't it more logical and beneficial for you to have stronger allies?" asked Ainz.

So that's what the earlier display of power for. It wasn't meant to threaten her. It was show they had advantage over her current organization in every way.

While the offer was tempting indeed but there was a problem with it.

"Even if I do join your side, I still won't do it permanently as my goal-"

However, Ainz put his hand up interrupting the Dragon God much to latter's annoyance.

"My subordinate, Demiurge, already told me you want to get rid of a very powerful Dragon named Great Red to reclaim your home and return back to it peacefully but alone you aren't powerful to defeat him. I can help you defeat him. With you having Nazarick support, I don't think he would be much of a challenge." told Ainz.

"And what do you want in return?" asked Ophis.

"Your help in upcoming war. I want you to keep supporting Khaos Brigade until we arrive at the war. After that, I want to take away from power you granted them." told Ainz.

"Why can't I refuse to give them power in the first place and leave the group?" asked Ophis.

"Without your support, Khaos Brigade is nowhere powerful as it is right now. I want them to be powerful enough to stand against each faction in the war so that they suffer heavy damage and casualties. Once every side in the war is significantly weak enough, we will join the war and you will take back your power from Khaos Brigade. I want to win this war with as few casualties to Nazarick as possible." explained Ainz.

"What will you do after winning the war?" asked Ophis.

"That is none of your concern or interest. But worry not, I will not make any move against you as long as you promise to do the same once you get your home back." replied Ainz.

"I can agree to those terms. So do I have your word that you will help me reclaim my home once I helped you, Ainz-dono?" asked Ophis.

"Do. Not. Doubt. Ainz. Sama. Once. He. Has. Given. His. Word." said the large insectoid.

"Cocytus is right. I don't have a habit of making empty promises." told Ainz.

"Then it is a deal." said Ophis with a smile.

"Good. I will take my leave now. My subordinates will walk you through the details of the plan." told Ainz as he teleported away.

After returning to his room, Ainz jumped onto his bed. He hung briefly in the air before his body sank into the bed.

"Aaahhh...man, that was so intense" said Ainz sighing deeply

Ainz was undead, so physical and mental exhaustion were foreign to him. But his human side was still tired of it. When he was alone in the room, that's the only time his human side got to let it all out.

"Seriously, that was a bold move to let that Dragon God inside the Nazarick. Judging by her energy alone, she could have really done a lot of damage to Nazarick if she refused and attack us instead. She is strong enough to a high level raid boss" said Ainz to himself as he rolled to his left side

"But even if she did that, I'm sure we could have defeated her, at least that's what Demiurge suggested. I wonder what kind of loot she might have dropped upon defeat."

This time he rolled to his right side.

"Still, I'm so glad we came to an agreement." said Ainz giggling quietly as he rolled around, "I wouldn't have wanted to face her in war. The more efficiently the work done the better."

That was something Suzuki Satoru had engraved in his mind when he got the job as a salesman in his previous life. It proved real helpful to him as a ruler too.

"Well, time to practice for my entrance pose!" said Ainz as walked towards the mirror.

UNDERWORLD

-FALLEN ANGELS TERRITORY-

"So this is the place where the meeting is being held?" asked Kuroka quietly looking at the huge mansion in front of her.

The entire building was heavily guarded. Magic detectors for any intruder and summoning circles for backup were placed almost everywhere.

"Yes. It seems due to the ever growing disputes among the faction, they have increased their security than last time" said Demiurge through his mask.

"Last time? That means you have visited this place before?" whispered Kuroka

"I did. Every part of Ainz-sama needs to succeed ensure victory in the war. I'm not foolish enough to come to this place without any prior knowledge." told Demiurge before looking at her, "You don't need to whisper. With [Perfect Unknowable] spell in work, we can talk normally. The magic detectors are useless against this spell. As long as we don't attack, the spell will hold. Let's go."

While this spell made Fallen Angels' security measures like bunch of amateurs at work, the mana cost of this spell was quite high. Demiurge was not a magic caster like Ainz-sama so he couldn't use this spell casually like he could.

He wanted the spell to break before they reached the meeting room.

The way to the meeting room was quite simple for the most part except when Kuroka had to kill some guards as the entry into one of the room was impossible without them out of the way.

With the spell effects gone, Kuroka was visible to enemies. However, she used her space-time manipulation and senjutsu to use stealth.

Demiurge smiled as he saw that. Her stealth abilities was the reason Demiurge decided to bring Kuroka with him. He could have chosen Raynare too but she was undergoing her training with Shalltear and her status in Fallen Angels wasn't high enough to get them past the security.

"We are here." said Kuroka as they stopped in front of the white doors.

"I TOLD YOU THOSE DEVILS ARE THE MOST DANGEROUS OF ALL!"

"We should think through this. War isn't our only way to settle this."

"Those angles might be waiting for our forces to get weak! No wonder they haven't done anything yet!"

Demiurge couldn't help but smile listening to all arguments of the higher officials. It seemed he may not even to use mind control this time around.

With a huge thud, Demiurge opened the door and entered.

"What the hell?! Who are you? " asked one of the Fallen Angels.

"A devil? How did you get in here?!" asked the other one.

In an instant, every Fallen Angel in the room summoned light spears to attack him.

"Now, let's not resort to violence. My name is Jaldabaoth. I'm not here to fight anyone. I came here to propose an offer." told Demiurge.

"And why should we listen a devil?" asked one of the officials.

"It's because you guys will perish if a war broke out. You guys are way too weak to contend with devils and way too vulnerable to fight against holy attacks of Angels. I can provide a way for Fallen Angels to gain an advantage over the other Factions." replied Demiurge.

"Don't you underestimate us, devil!" said another voice from the officials.

"I would appreciate if you stop including me with those miserable insects." said Demiurge in dangerously low voice making everyone flinch, "Anyways, what I said is absolute truth. Do you really think anyone of you can defeat a super devil like Sirzech or the Satans?"

Nobody was able to reply to his question. It was a bitter truth than nobody wanted to admit. No one among Fallen Angels' army can stand toe to toe against a monster like Sirzech.

"While you guys are desperately trying to find a way to ensure the surivi2of your race. One of your leader, Azazel, is too busy babysitting the little sister of your enemy's leader instead of helping his own people." reminded Demiurge.

"WE ALREADY KNOW IT, DAMMIT! NO NEED TO REMIND US THAT!" yelled one of the officials.

"That traitor is only good at licking the boots of those devils!"

"Fucking A-grade ass kisser!"

Demiurge's smiled widened hearing this. He has already added fuel to the fire. Even if Azazel now comes up with a suggestion to stop war, at the very least the officials will be divided.

"Let's get back on the topic. You all know a war is inevitable. I can provide you an endless army of demons. I can even make those angels who are neutral so far turn against devils." told Demiurge.

Everyone was surprised to hear that. Providing someone their army in the war is considered the biggest show of trust and it was something that Fallen Angels desperately needed.

"What's your game in all of this? What do you want from us in return?"

"A position as one of the leader of Fallen Angels after we win the war." replied Demiurge

Silence fell in the room as Demiurge said that. Under normal circumstances, these Fallen Angels would have laughed at such proposal but right now, it didn't seem like a bad deal.

"So you will provide us with an army of your own and will make angels participate in this war too? How?" asked one of the officials.

"Just leave that to me. You will know when that happens. So do we have a deal?" asked Demiurge.

There was another few minutes of silence in the room before a Fallen Angel spoke

"Whom so ever agree with Jaldabaoth's offer raise your hands up."

In a matter of seconds, everyone had their hands up in agreement.

It was a guarantee from the beginning that everyone would agree. Demiurge had already predicted this even from the beginning. Beggars can't be choicers.

It was either perish in a disadvantageous battle or join forces with a strong ally. The choice was obvious.

"Excellent. Trust me everyone when I say you wouldn't regret this decision." said Demiurge his smile hidden behind his mask.

A/N: I hope you guys enjoyed this chapter. Fun fact: the broken abilities in hax can and has been countered by pure strength and stronger characters alone.
