Y/N had a deal Aura surrounding him as he look at Cosmo.

Cosmo on the other hand was shaking in fear as he knew that he has pissed his sensei.

Cosmo: I'm sorry sensei please forgive me.

Cosmo said as he was kneeling infront of Y/N while having small bits of tears fallikny off his face.

Y/N: fine i will forgive you this once but next time it happens I am not going to take it lightly understand.

Y/N said as Cosmo nodded at this hile sill shaking in fear.

As Y/N then stand back up straight and the dark aura surrounding him suddenly disappeared.

As he had his genuine smile back as this made Astral and Nebula dumbfounded.

First they saw that there sensei was about to punish Cosmo as he was like a devil.

And now he looks like an angel that did nothing wrong.

As the other two noted that tht should never piss there sensei or else.

Just thinking about it made the two shiver in fear about it.

Artoria on the other hand could not help but giggle a bit on seeing her husband change of attitude.

Neo was confuse if what happened as she did hear anything other than being her ears covered by Artoria hands.

Neo: mommy why is Cosmo kneeling and crying infront of daddy?

Neo asked with a cute and confuse look on her face.

Artoria: it is nothing that you need to concern of Neo.

Artoria said as Neo nodded at this as she just look at them.

Morgana: your husband is very scary.

Morgana whispered towards Artoria as even she can't help to shiver abit from the black Aura.

That Y/N was releasing a few moments ago just thinking about it made her spine shiver.

Artoria: don't you mean our husband?

Artoria asked with a teasing smile on her face as Morgana blush at this.

As she still can remember the taste of Y/N when the both kiss several moments ago.

Morgana: s-shut up big sis we are not m-married ye.

Morgana said as she blush red and turn to look away from her teasing sister.

Artoria: oh don't be shy afrr all your my sister and we have the same husband now.

Artoria said teasingly even more as Morgana could only cover her face in embarrassment at this.

Morgana: what an idiot of a big sister you are.

Morgana said as Artoria made a hurtful look on her face.

Artoria: hah my sister hates me.

Artoria said as she fake cry while looking at Morgana.

Morgana: oh stop fooling around sis your not a baby.

Morgana said as she had a angry look on her face that kinda makes her very cute.

Artoria: aww I was just teasing you no need to take it seriously.

Artoria said as she then turn around and look at Y/N.

Artoria: so what is the plan Y/N?

Artoria asked as she turn to look at Y/N who was looking at giant 100 meter tall door on the other side.

Y/N: I got two option one we break into it the easy way which is to just sneak past them or the hard way as we break through them while killing the in the process.

Y/N said as the others all had a deadpan look on there faces.

Artoria: really Y/N that your idea?

Artoria asked with a deadpan look on he face as it was obvious on which plan tht would take.

Y/N: I was just joking g no need to take it so serious.

Y/N said as the others all sigh and chuckle a bit of this.

Neo: okay then let go Papa.

Neo said as she was about to go in her shadow form.

But was quickly stop by Y/N who grab hold onto her arm.

Y/N: no your not Neo I am the only one that is going in all if you stay here.

Y/N said as the other had a shock look on there faces when they heard this.

Artoria: are you crazy Y/N that would be suicide your going.

Artoria said with an angry look on her face as she cannot simply let her own husband to go inside alone.

Y/N: the black stone only reacts when I get near it and I don't want all of you to get hurt so please Artoria you all stay behind while I go and get the Black Stone.

Y/N said as he turns around as it made Artoria even more angry at this as she walk infront if Y/N and hug him tightly.

Artoria: I won't let you go alone Y/N please let us come with you.

Artoria beg with tears in her eyes as she hug Y/N very tightly.

Y/N: no Artoria it is not your choice to come with me.

Y/N said as Artoria and the others suddenly could not move.

Artoria: Y/N what are you doing let us go!

Artoria asked with an angry look on her face as tear was flowing out of her eyes.

Y/N: I'm sorry but it is for you own good and the others as well.

Y/N said as he made a barrier surrounding them as they can move agan.

Neo: no daddy please don't leave us I beg you take us with you.

Neo beg as she try to smash the barrier but couldn't.

Artoria: if you don't let us go Y/N I am going to hate you for this.

Artoria said with tears in her eyes as the two try to break the barriers but couldn't.

Y/N on the other hand smiled sadly at this as he turns around and unsheathed his katana.

Y/N: I'm sorry girls but u have to do this on my own I'll be back don't worry about me I'll be safe.

Y/N said as he jump down the floor and into the bottom below.

As he could hear the two girls screaming for his name.

Morgana and his students all console them as they knew that you would be back.

As Y/N landed on the last floor of the dungeon he was met with billion of demons.

As they all look at him and Y/N stand up and lok at the.

Y/N: move aside if you all don't want to die.

Y/N said but the answer he got from them is they all charge at him with there weapons.

Y/N sigh at this as he closed his eyes and immediately access the power if the Pandora Box.

Y/N: fine then let us do this the hard way then.

Y/N said as he open his eyes and the whole universe began to shake from the massive power he was releasing.

Outside you could send everyone all froze from the massive amount of power they are feeling right now.

Jalter: what is going on why can't I move?

Jalter asked as she try to love but couldn't do to the massive power being released.

Walter: Y/N must be using his full power right now.

Walter said as he uses a barrier to cover them as they can all now move.

Nero: what is Y/N doing is he fighting someone?

Neo asked as Rose look to where the power is being unleash right now.

Rose: perhaps he is facing someone right now.

Rose said as she and the others could only pray for Y/N to succeed.

Back at Y/N we could see his hair had turn as black as the night sky itself.

As he look at the frozen demons with his right eyes glowing black and red whole his left eye was glowing white and gold.

Y/N: all of you die.

Y/N said as he slash his sword and immediately all the demon that were in the attack range of his sword were destroy immediately.

As he then walk towards the door were the Aura of the black Stone is being released.

The demon that are still alive try to stop him.

But his Imperial Eagle form riggings appeared and beagn to decimate them all out of existence.

As he walk closer to the door the massive red eyeball look at him.

As the power of the black stone started to surround the eyeball and immediately fired a beam.

Y/N seeing this made a portal open where it absorb the beam attack.

As he continue to walk the door while slicing and blocking any attack from the giant eyeball.

Y/N: okay you are getting annoying now.

Y/N said as he aim his riggings and immediately said.

Y/N: Lock And Fire.

Y/N said his riggings launch several hydrogen class bombs at the eyeball.

Causing the whole dungeon to erupt and immediately made the the ground above to burst.

As the eyeball was destroy but the gat still stand.

Artoria and the others were all safe as they are being protected by the barrier.

As Y/N was about to open the door a massive Roar made him stop.

Y/N: what the?!

Before Y/N could react the door burst open and out came a giant demonic Dragon that has the blak stone attack on its chest.

As Y/N was blown away and was flying into the air.

Meanwhile with the others they were shock when they saw the giant Dragon appearing out if the destroyed city.

Rianna seeing this laugh loudly as she knew all of them are doom.

Rianna: all of you are doom with the black stone attach to the Demonic Dragon Emperor Azuren no one can stop him.

Rianna said but Walter and Rose knew that Y/N will win this.

Walter: are you sure about that?

Walter asked with a smirk on his face as this confuse Rianna when she heard this.

Rianna: what do you mean no one can stop Azuren.

Rianna said but then they saw the massive draconic Dragon being blown away by a unkonw force.

Back with Y/N we could see him looking at the demoinc Dragon as he aim his cannons and fired.

Y/N: Absolute Zero!

Y/N said as he fired a blue beam that went flying straight to Azuren.

As the dragon saw this and breath black flames at Y/N attack buy it was overpowered by Y/N attack.

As the beam then hit the wings of the Dragon making it shatter to pieces.

As the Dragon fall back into the ground below.

But Y/N acted fast and immediately lunge at the dragon.

Azuren saw this as it growled and immediately fired dozens if spears made of nether at Y/N.

Y/N saw this he immediately used his sword to slice it in half

As he jumps onto one of the giant Spears and aim 2 of his Super Heavy Antimatter Gravity Railgun.

As he fired it and immediately two beams of black and red went flyin straight to the dragon as it hits the chain that attach the black Stone to it

Y/N: now is my chance.

Y/N said as he flew faster than the speed of light and immediately he made contact with the black stone.

As blinding light envelop him and the everyone else.

As he closes his eyes for a few minutes before opening it back up.

As he was now standing infront of a world he has never been before.

Y/N: wait where am I?

Y/N asked as he look around as he was standing on a grass land but he could de the immense energy flowing in the world he was in.

Suddenly the familiar screen that he met before he was transported to the Azur Lane Universe.

AI: we meet again maker congratulations you have now full access to 95% of all of Creation you also have achieved the power to control over the power of the Ancient Primordial Omnipotent.

The AI said as this suprise Y/N when he has heard of this.

Y/N: thank you but where am I?

Y/N asked as he wonder why this place actually is.

AI: you are in the Ancient Primordial Origin Domain Of Creation it a gift by the maker when you have collected the second piece with the place you have access to the Ancient Primordial Aetherium Army no one in existence of none existence can't defeat this army or even any high level dimensional being and if you ask if what you humans call the FBI and Thot Patrol of Godlike power could defeat the Ancient Primordial Aetherium Army no they can't as I said the Ancient Primordial Aetherium Army is the supreme soldiers that will serve under you.

The AI finnish saying as Y/N could only look at the AI with weird look on his face.

As he does not care about what the FBI or THOT Patrol is more ever she is shock about the army he as acces to.

Y/N: so how many are they?

Y/N asked as the AI the spoke tha shock him.

AI: they are Infinite and all you need to do is to think of which soldier or tanks, ships and other military units the Ancient Primordial Aetherium Army has.

The AI explain as Y/N nodded at this as he thought about it.

Y/N: okay how can I get out of here then?

Y/N yet again asked back the AI as HF dismiss the army I inftont of him as they all disappeared.

The AI said with a seductive tone to it as this surpise Y/N and before he could ask the AI turn into a beautiful goddess.

As she floats infront if him and give Y/N a kiss on the lips and a wink before disappearing.

Y/N was in a daze at this as he snap out if it and immediately laugh before he then woke up.

As he woke up he was met with Artoria hugging him tightly as they are in a room.

Artoria aaw Y/N waking up as this brought joy to her as she kisses and smack him in the head.

Artoria: you idiot you almost has me worried.

Here I am now standing infront of a balcony as down in the middle we could see Rianna ties to a pole.

I exhaled some bits of air and then immediately spoke

Y/N: we are all gather here to judge the crimes that Rianna Claudia has committed anyone who like to speak may do so now.

Da Vinci announce all the crimes that Rianna has committed.

And after several announcing of her crimes Da Vinci finnish speaking.

Y/N: Rianna Claudias do you have anything to say?

I asked as I look at her and she look at Nero with a begging look on her face.

Rianna: sister please save me!!!

Rianna said as Nero only look at her in hate as she could not forgive of what she did to there Father.

Nero: it is to late to save you I cannot forgive of what you have done for are father you deserve to die.

Nero said with anger in her eyes as I sigh at this and look back at Rianna.

Y/N: Rianna Claudias do to the many crimes you have committed you are hereby sentence to death by burning in a stake.

As I finnish announcing she began to beg to me to give her mercy but i did not listen to it.

After all she has already failed to ever since she have started the war.

One of my soldier was carrying a torch as he step closer to the pole of stakes beneath Rianna.

Rianna: no I beg you Emperor Y/N give me another chance.

Rianna said with a look of despair on her face as I merely sigh at this.

Y/N: you already have lose that chance death is the only thing awaits you know

I said as Rianna had a look of despair as the soldier then throw the torch into the stake.

And immediately fire began to surround Rianna as she scream in pain as she slowly being burned.

I turned around with the others following me behind.

Walter: well that the end of it Y/N what all you do next?

Walter asked as he turn to look at me as I smile at this.

Y/N: I still have a wedding here to prepare.

As I said that the girls all blush at this as they ran to get some wedding dress for all of the to wear.

But I still wonder when I will meet that woman that I met inside the Pandora Box.

She did say when the last piece of the Pandora Box is found we will meet again.

Thinking about I just can't wait to meet her again after all I'm an anomaly that always helps.
