Hello guys sorry for being away too long i was busy working around the house having to do. So as for waiting so patiently i'll do both the climax of the story and epilogue hope you enjoy.

Roon Pov

This green guy has triple the strength of Friedrich der Grosse she is the strongest there is i then notice something on the wall as it was glowing green.

Roon: Girls i've found something of interest.

Nelson: Hmph I bet its not worth much.

Roon: I don't need your input you tsundere.

Nelson: Hey that was rud-

Roon:I don't care and if you don't shut up i'll just put you to sleep.

Nelson eventually closed her mouth.

Roon: Good now then this. Bismarck this is roon i need your help with something can you come over to us we're at midway.

Bismarck (over radio) Will do i'll come along with Hood Warspite,Akagi,Kaga,Shoukaku,Z23 and Graf Zeppelin.

Roon: Nice then we will protect this area ready to-

???: Oh it seems this is one of your testaments.

Roon: What? Doomslayer?

Vega: It appears a testament has arisen in this realm it shouldn't be here.

Roon: What are testaments if i may ask?

Vega: They are something the demons should always be afraid of after all he is ruthless to them.

Scharnhorst:Hey Roon who is that guy?

Roon: Doomslayer or Y/n.

Scharnhorst: i see. I overheard something about a testament.

Vega: Yes the Doomslayer is merciless to them they destroyed his home it was named Argent D'Nur.

Y/n: It was Peaceful with no war that was until the demons came and destroyed my very home now it is abandoned.

Roon/Scharnhorst: I'm sorry if i brought up any unpleasent memories from the past.

Y/n: It matters not we need to stop the invasion im sure your commander should be able to come up with a strategy to fend off the sirens.

Roon: you're right we'll prepare the defences.

10 minutes later Bismarck arrives.

Bismarck POV

I was called out by Roon as she saw something that caught her interest to call me for help.

Then I see this green glowing lot of rocks which caught Roon's interest.

Bismarck: What is this please tell me this isn't a joke to lure me out.

Roon: I'm not luring you out in fact i just learned from Y/n that this is one of his testaments in demonic language.

Bismarck: Since all of us are here let us hear what it has to say.

After listening to the testaments i was generally scared of him i didn't know that he became one of the demigods a seraphim bestowed the young warrior terrible power his hatred his fury.

But what i didn't know is that he was a demon hunter i saw a separate testament a red one. I pressed it thinking it was the same but this one is different.

As the doomslayer defeated the icon of sin he set forth without no mercy and crucified every demon on sight. His unbreakable will showed no quarter of fear and no quarter of his wrath. With the genophage of the demons now with in his sight he ended the dominion in the darkest of pits and came out unscathed. He is the demons worst nightmare he is Doomslayer.

I was truly horrified with the disturbing images showed by the testament i'll have to becareful not to get scared around him.

A loud demonic roar was heard from the nearby island

Hood: What the hell was that?

Akagi: That sounded demonic like something invaded our world.

Y/n knew what this meant as alarms were triggered alerting all shipgirls to his position.

Bismarck,Hood,Warspite,Kaga,Eugen,Hipper and Scharnhorst Sprinted toward the loud roar and saw a tall being covered in armour and a glowing axe with a skull with Y/n.

Y/n POV

???: You were never one of us.

A Human against a maurauder a former sentinel

Maurauder: Two titans of power shall battle to the death both demigods of death

Y/n: I got time for a battle to the death.

Loud shock waves were felt as the battle started.

Maurauder: Is that all you got?

y/n pulls out his super shotgun and unloads two rounds into the Maurauder

Maurauder:Tch! You'll have to do better than that to kill me.

Y/n: I can make that happen easily.

Y/n Puts his shotgun away and pulls out the crucible.

Maurauder: NO! Where did you get that?! You wield the most powerful crucible and you use it as a weapon.

Y/n didn't answer and his response was activating the blade.

Y/n: Come at me bro. He taunts

Maurauder: You! You defy our traditions to-

Y/n: By killing millions of people just to save yourself you deserve to die they didn't do anything wrong all they wanted was to supply the world's power.

Maurauder:Tch! i will have your head after this.

Y/n decided enough was enough and used berserk.

Maurauder: how about i kill your commander hehe.

That made y/n's blood boil the sea was even starting to warm up.

Y/n You leave him out of this or i'll murder you into next week!

Bismarck POV

As the two titans clash all i see within the doomslayer was his inner demon his eyes slowly turning between red and blue his rage ready to be let out. Why do i feel like he is hurting on the inside?

Hood POV

There was Something in Y/n i cannot describe i felt something warm i looked to find the sea begining to boil.

Hood: Everyone get to land now the sea is starting to boil.

Everyone got out of the water as the sea boiled.

As i watched from the shorelines the Maurauder became defenceless as Y/n went for the kill but caught of guard as the Maurauder kicks the doomslayer through a mountain.

Roon POV

I don't want to mess with him anymore he is lethal.

Akagi POV

I want him I want him so much us two would make beautiful children.

Warspite POV

I won't last 10 seconds against him he is so strong is there a limit to his strength?

Queen Elizabeth POV

All of a sudden my feet got very hot i told everyone to get out of the water.

QE: Who in the world would make the sea boil?

Illustrious: Your majesty i believe it would be the Doomslayer he is fighting some powerful foe.

QE: I'd like to think you are right.

Y/n POV

I'll end him once and for all

Y/n: you want to taste death be my guest. Full power!

My Rage explodes causing the earth to shake tidal waves begun forming a huge cyclone of wind in the centre of the battlefield.

Y/n: You...Will....Suffer.....for.....this!.....RRAAAGGGHHH!!!!!!

No one pov

As y/n's rage explodes he enters berserker mode his eyes blood red blood started seeping out from the eye sockets and nose.

Y/n: This....is.....not....over.....i...will...give...you...violent pain.

His movements have changed from sharp to razor sharp almost acting on instinct.

Maurauder: So you've finally awoken that hidden side of you good this battle has just begun.

Y/n: ...

Maurauder: Heh Just the way i like it.

Y/n went straight for the kill instantly killing the Maurauder

Friedrich der Grosse POV

What is this imeasureable aura that's been generated? first i moved closer toward the source and found Y/n but his movements changed so much almost inhuman no matter as long as my symphony and my child are fine then i am myself.

I knew he was strong but not this strong. Is that blood on his eye sockets?

Y/n POV

My Eyes were completely red and bloodlust took over rage took over all of my muscles were shredded i had a killer intent on murdering this bastard who calls himself Maurauder.

Y/n: You'll die at my hands you will never see the light again.

After slicing the demon's head i felt all my anger dissappear.

For once i feel at peace like i do not need to fight anymore.

Then I see other shipgirls who were jaw gaping shocked at the display of strength i demonstrated.

Y/n: Did we win?

FDG: Yes we did dear.

Y/n (thoughts) Wait did she call me dear i haven't been called that in eons since i was trapped in hell.

Z23: Friedrich tends to be a motherly figure to all of us including you.

Y/n: I see thank you for your support Friedrich.

FDG: Anything for you dear. I shall walk the earth with all of you if you ask.

Y/n: Thank you now lets go enjoy some beers.

Bismarck: I didn't take you as a drinking type.

Tirpitz: Nor did i.

Y/n was taken to the medical ward to treat some of his injuries he sustained while fighting.

Doomslayer brought something out from his warp pack it was his sentinel beers and there were hundreds of them.

(Jesus how much can that warp pack fit in?)
