Aright This is the only other solid akame ga kill crossover I'm gonna be honest only one akame ga kill crossover exists but even then it's not even Ainz it's some rando OC anyways all the others are one shot trash hopefully mine isn't a oneshot trash
The empire was a great country this was because of a great ruler who had the tools needed to create a utopia and that he did in the form of an empire but this utopia could not last forever as the emperor was only human and thus had a human lifespan the emperor knew this and thought about how other countries could take over his empire so he created exceptional weapons called teigus. These are powerful weapons that could give a normal person a superhuman level of strength some of which could destroy armies there were 48 of them. For many years the empire was at peace until a civil war broke out which resulted in either their destruction or were lost the empire had lost half of them which resulted in a huge blow to the empire fast forward many years later. The Empire which used to be a utopia has become a living hell for its inhabitants because of the rampant corruption that has been happening everyone suffers.
However, on the borders of the capital is a giant plain of mountains however those plains hide something more sinister within hidden is a sort of giant mausoleum and within it is a powerful presence that has just made its way into this world this mausoleum is the great tomb of nazarick home of the guild ainz ooal gown and its NPCs deep within is a series of floors and each harder to get through than the last it was made by the 41 supreme beings however despite this only one remained he lives deep within the tomb. In the throne room of nazarick was death himself or rather what would be the depiction of death. In reality, this was Suzuki Satarou a former salaryman from a polluted world he is simply stuck in the form of his avatar Momonga. Next to him was a beautiful woman dressed in white only she had curved horns on her head and black wings on her waist but what stood out was her beauty if she wanted to she could seize anyone with just her looks alone she was what many would describe a goddess however despite her beauty there was one man she could not charm or seize and that man was next to her. Momonga was using the mirror of remote viewing to practice with it.
(Author's Note: This takes place after the day ainz made a joke about world domination also I prefer not to describe a character's appearance because you'd already know what they look like)
"Albedo"
"Yes my lord?" Albedo replied earnestly
"What do you think of humans?" Momonga asked because he was curious about how much of the settings affected an NPCs Personality
"I think they are disgusting lower life forms that should just obediently die." She replied coldly
Momonga didn't reply any further and continued practicing he couldn't get it right because controlling where the mirror would show was tricky.
It was the next day and this time he was with Sebas he was his butler for the day Momonga was in his office this time and once again was practicing with his mirror until he finally got a grasp on how the mirror works once he did he heard clapping
"Well done my lord"
Momonga couldn't tell if its actual praise or if he was sarcastic either way he paid it no heed. Looking at the surrounding area were forests plains there were even several villages. One however caught momonga's eye it was a village.
"Hmm, A Festival?"
"I don't think so, my lord."
Taking a closer look the village was being burned down and people were stealing from the houses, killing the men, kidnapping the women, and many more acts against humanity however despite this Suzuki Satarou felt nothing towards their deaths.
"What shall we do?"
"Leave them be there is no reason for us to intervene."
"Understood."
Looking at sebas it reminded him of Touch me a guildmate of his then he remembered the time touch me saved him from an endless cycle of PKing. "Saving someone weaker than you is the right thing to do." That was the philosophy touch me lived by and this time Momonga would follow that philosophy
"Sebas, I'm going to this village Raise the security level of nazarick to maximum and tell albedo to arm herself"
"Understood"
'Touch me I will repay my debt to you'
[Gate]
Then a swirling portal appeared and Momonga stepped into it.
The Bandits were having a blast the village was targeted by bandits because of the goods it had and so they were doing whatever they want like stealing, killing, doing unspeakable acts to the women, Killing parents in front of the children and many more this was because of the sheer corruption in the empire taxes were raised unreasonably high, the people died of starvation or were barely getting by. Now this village is one of many that fell victim to the empire's corruption well supposed to be. Three bandits were chasing a young woman who was protecting her little brother the bandits who were chasing them into the forest had perverse thoughts about what they could do to her such as forcing her little brother to watch as they do unspeakable acts to her or killing her brother as they forced her to watch. They had now cornered their prey the girl was injured and could barely move.
'This is it I'm going to die just like dad they're going to kill me or worse. What will they do to Shoto'
She hoped for someone anyone to save them from this injustice however deep down she knew justice wouldn't punish these men she closed her eyes and prepared for the worse, but it never came. Now onto the bandit's perspective, they stopped because there was a black swirling portal the soldiers paused.
"W-What the hell is that?!"
"Could it be a teigu?"
"What the hell is going on?!"
Before they could attack a figure stepped out of the portal it wore an elaborate, jet-black academic gown adorned with golden and violet edges it was also holding a staff made of gold on top were snake heads that each had a gem in its mouth each gem had different colors however what really terrified the soldiers were its face it was a skeleton however what was in its eye sockets were two bright red flames as if it was fueled by nothing but hatred this was the incarnation of death at least from what they heard from fairy tales the bandits were speechless until.
"K-Kill It S-Send it back into D-Depths of Hell!"
The two bandits tried to rush at it with their swords to slash it but when they slashed it did nothing to the skeleton it was as if it was protected by a barrier.
[Grasp Heart]
A heart then appeared in the skeleton's hand and then he crushed said heart and one of the bandits fell to the ground the other two gasped there was a few seconds of silence until
"I was thinking of retreating if my favorite spell didn't work"
"W-What the hell are you?! W-Who are you?! Do you have any idea who you're dealing with?! You're up against the Reia Clan?! We'll make sure to send you back to that shit-stained coffin you call home!" The Soldier shouted with fear in his voice.
"Is that so? Because all I see is a gathering of cowards and fools who prey on the weak, What kind of man has the nerve to harm a woman and a child but does not have the guts to face me."
"Y-You I will kill you! And then I'm Gonna Kill Everyone in this shit hole, And then I'm gonna steal all their shit and your fancy little teigu, and then-" Fear turned to Rage and as he was about to finish he was interrupted
"How Tiresome [Dragon lightning]" A Huge surge of electricity appeared on the skeleton's hand then the electricity rushed to the rambling bandit and instantly fried him
"How pathetic dying to a mere 5th tier spell" The skeleton spoke
[Create Middle Tier Undead: Death Knight]
A black Ooze appeared on the body of the fried bandit before he was engulfed. Then it started to get bigger until it formed a big humanoid monster who had a broad sword and a tower shield as well as armor. The last bandit had already started to flee.
"Death Knight kill that man"
The monster roared and at surprising speed caught up to the man and he was cut in half like butter with the flamberge then the Death knight returned to its summoner.
"Death Knight kill anyone in the village that is terrorizing the villagers"
He pointed at the dead man on which he used [grasp heart].
The monster roared furiously and sped off out of the forest. Another Figure came out of the swirling portal she wore an impressive black full plate armor with a unique helmet and is carrying a battle ax the figure then pointed her weapon at the siblings. Meanwhile, the older sister was too terrified to say anything not even a plea for mercy.
"The preparations took some time I apologize."
"No. Your Timing is perfect Albedo."
"Thank you very much Now shall I dispose of these lower lifeforms?"
"No. For now, those that are wearing that amour are our enemy"
"Understood"
Momonga pulled out a healing potion from his inventory
"It seems like you are injured. Drink this"
"B-Blood? I-Ill drink it but please I beg of you spare my little brother"
"Big sis NO!"
'What the hell is this? They don't trust me at all what did I do wrong?' Suzuki thought while they were arguing then Albedo raised her battle ax at them.
"You Ungrateful Lower Life Forms!"
"Albedo Stop! Lower You're Weapon!"
"Understood." She then lowered her weapon reluctantly Momonga then crouched to reach their height
"I can assure you this is not blood this is a healing medicine that can cure your wounds" His voice was soothing the girl felt safe when she heard it. The girl then accepted the potion and drank it and as if magic was cast on her the slash wound disappeared, she was amazed by the mysterious skeleton she even considered that she may be dreaming but the earlier pain tells her otherwise
"It's gone now right?"
"Y-Yes"
"Tell me who are the men destroying your village?"
"T-They are Bandits they intend to loot our villages and kidnap the women"
"I see do the soldiers do anything about it?"
"N-No the soldiers don't do anything since the bandits just bribe them"
"I see"
'Sheesh talk about selfish'
"Do you know what magic is?"
"Like from fairytale books Wait can you use magic?"
"Yes now hold still for a moment"
[Anti Life Cacoon][Wall Of Protection From Arrows]
A Large green dome surrounded the siblings
Then Momonga started walking away to the outside of the forest
"W-Wait" Momonga stopped in his tracks but did not turn around
"Thank you Thank you so much P-Please Tell me your name!"
It was a moment later that Momonga turned around the literal fire in his eyes grew brighter his menacing aura flaring up "Remember This name may it carve into your being for the rest of your lives! …. My Name Is Ainz Ooal Gown!'
Within the village was complete bloodshed normally the blood would be from the inhabitants of the villages but this time was different it was the bandit's blood that was being shed normally it would be the revolutionary army that would attack the bandits but this time it was a monster no one expected. Bullets had no effect on it Sword would shatter on the impact on its body, Spears would snap like twigs in one thrust no attack worked on the beast
"Dammit what the hell is this thing?!"
"Is this a new danger beast?!"
"Use the villagers as shields!"
The Death Knight was slaughtering all the bandits one by one it definitely helped that all the villagers were grouped up so the death knight could at least tell the difference between who to kill and who to not kill anyways one by one the death knight slaughtered the bandits that came to charge at the monster those who ran away were killed first and brutally at that they were either cut in half like butter or crushed. there were those who used the villager as a meat shield but the death knight would move so fast to get behind them and kill the person who was using the villagers as meat shields while also leaving the villager unharmed then something absolutely terrifying happened to some of their comrades slowly rose back up to their feet at first they thought they were alive but when they saw their decayed faces they knew their comrades were no more. slowly their numbers dwindled until there were only 9 of them left that was including the leader the remaining ones were the ranged support so now they no longer had any melee combatants.
"A-Are we gonna die here?!"
"Shit I can't go out like this!"
"If only we had a teigu user we could stand a chance against that thing."
"Everyone calm down I'm sure that thing has a weakness we just need to find it"
"Death knight Stop!"
The Monster obeyed the voice and stood still as a statue All the bandits turned their heads to see a bear of a man wearing a mask with a mocking smile he wore a robe and metal gauntlets. Next to him was a more slender figure they can't tell if it was a man or a woman as he/she was wearing full armor he/she also had a huge battle ax. The masked figure started walking towards them
"Good afternoon my name is Ainz Ooal Gown and I have one thing to say to vermin such as yourselves"
Then they could feel a powerful menacing aura coming from the man
"Surrender and I'll make your deaths painless or Fight and know the true meaning of hell."
(Author's note: I'm gonna skip this fight scene because we already know where this would be going forgive me)
The bandits were captured alive they mocked Ainz's name talking about how only a loser would come up with that Ainz had ordered for albedo to return to nazarick with the bandits to be interrogated by neuronist however he gave her the guise of turning them into the authorities the village chief was at first very distrustful it was only until ainz asked for compensation that they lowered their guard he had also erased the memories of the siblings on about how he can use magic all they remembered is that Ainz Ooal Gown had saved them and gave them horns that could summon goblins. Anyways Ainz was talking to the village chief apparently this is called Cain Village and this was one of the least protected areas but the taxes were also high apparently the reason for this was because of the empire's corruption however despite the corruption this was the most powerful country on the continent this village was on the brink of starvation thanks to the taxes.
'Jeez talk about corruption this empire could be trying to compete with the NPCs on who is crueler'
"Well It seems the sun is setting soon so I must take my leave"
"Ah yes please take care lord gown"
Ainz went into the forest and when no one could see him he used [Gate] and returned to nazarick
One day later
Everyone was in the throne room of nazarick on the throne is Ainz Ooal Gown
"Firstly I apologize for acting on my own. Albedo will tell you what has happened. However, there is one thing I must say Immediately [Greater Break Item]"
Momonga flag immediately burned into nothingness
"I have changed my name. From now on my name is Ainz Ooal Gown. You shall call me Ainz! If you have any objections voice them now!"
"We have heard your precious name. We devote absolute loyalty to our venerable leader." Albedo said earnestly
"Hail Ainz Ooal Gown!"
"We shall give ourselves completely to the supreme one," Shalltear said earnestly
"To the most powerful king." Aura and Mare said at the same time
"Everyone in this world will know your greatness."
"The one who rules over all our king."
"Glory to the Overlord, The ruler of death!"
"This is an absolute order! Make Ainz Ooal Gown an eternal legend!"
'So that my name may reach my friends that may come to this world'
With that Ainz teleported to his room
"Demiurge. Tell everyone about your conversation with Lord Ains" Albedo wants to let everyone know about her master's plan
"As Lord Ainz gazed at the night sky he told me this: "I may have come to this land to obtain this untouched box of treasures." And in the end, he said this: "Taking over the world might be enjoyable."
"Everyone knows that the final goal of the great tomb of nazarick is to present this world, this box, to lord ainz!" Albedo announced
There were many cheers unbeknownst to ainz himself.
