O.R.C club house a run down school house but that is only to does that are not from the supernatural world has behind its walls are luxurious rooms, baths and meeting rooms

The skies are blue, the clouds are fine and the sun satisfies the world with its light has we zoom towards the front door of the club house going through it we enter inside where in the living room sitting in their comfy couches and chair are the members of the O.R.C

Rias Gremory
Akeno
Koneko
Kiba
Shitsei
Asia
Xenovia
Gasper

Rias Gremory the heir to the Gremory name and king of her peerage sits on her throne pondering something which the other members take notice of this with Asia being the first to ask

Asia:Rias is everything okay?

Rias:Huh? *snaps out of her thoughts* oh Asia don't worry I'm fine *smiles* I just have a feeling

Kiba:What kind of feeling Rias?

Shitsei:Is it a good feeling? like maybe a feeling that something wonderful will happen in my bed later tonight *pervy smile but gets hit* Gaah!

Koneko: *punches him in the gut* Shut it perv

Rias: *giggles* No not that kind of feeling

Xenovia:Then what's troubling you master let us help you

Rias:Thank you Xenovia but it's just that I've been having this bad feeling like something bads gonna happen soon to us

Everyone:What!?

Akeno:Please do not make jokes like that Rias~ you just might give me a scare~

Rias:Right *nervous chuckle* sorry everyone for worrying you

Kiba:It's fine

Asia:Yeah I'm pretty sure nothing bad is gonna happen

Gasper:Yeah *smiles*

Xenovia:And if there is we'll be ready *nods*

Rias could only smile at her peerage trying to cheer her up and it did as everything went back to being calm and relaxing with Kiba reading a book, Koneko eating her sweets, Gasper hiding in his box, Asia sbd Shitsei talking to each other, Xenovia sharpening her sword, Akeno drinking tea and Rias just sitting on her throne thaf until

Xenovia:Has anyone seen Rossweisse Sensei?

This made everyone look at Xenovia confused but that's when the question hit them ¿Where is Rossweisse?

Akeno:I've ask myself that right now didn't she say she would be arriving sooner

Kiba:Maybe the meeting with the other teachers is longer than what she thought

Rias:Hmm maybe

Shitsei:Hmm? any one else hears a shotgun sound

Everyone looks at the pervert in confusion that's when they ear a loud "BOOM!" coming from outside has the doors to club house burst open and a figure can be seen flying towards where Rias is

Luckily fir her Shitsei and Kiba both caught the person before they could have hit Rias but once they landed and got a hood look at who was laughed into the room their eyes widen as they see

Rossweisse

Bruises and cuts were all ver her body and her armor had cracks and was even missing pieces

This only brought even more shock to the members of Rias peerage

Asia: *shock and scared* W-Who could have done this?

Shitsei:I don't know but whoever they are *summons his boost gear* they'll pay

Footsteps-no stomps can be heard approaching them given them all chills that go down their spines has they felt something menacing coming straight to them

Rias: *looks at Asia* Asia please heal Rossweisse we will handle our 'guest'

Asia: *nods worriedly* O-Okay

Rias:The rest of us let us go see what our guest wants

Everyone:Right!

They nod and quickly made their way towards the now destroyed door that is replaced with a huge hole, they all got in front of the door way that's leads to the meeting room as they all see who's attacking making them worry even more

It was a muscular man, wearing an apocalyptic like armor that covers him from head to toe with only human parts that reveal themselves are his big muscles, he had a small shoulder cannon on his left shoulder and his right arm was hold a right like assault rifle gun

This man he is the one all heroes and villains fear, the one that knows how to get things done right, the one who's fought armies of demons, devils, fallen angels, arc angels, heroes, huntsman, ninjas, assassins, life fiver users, ship girls, mech users and so much more

He goes by many names but two of those names are what make him stand out the most the most important one being The

Doom Slayer

Or has his friends and girlfriends call him

Rias: *shock* Y/N?

Doom Slayer:. . . . . . . . . . . .

Shitsei:Y/N? what the he*l are you doing here!? and why did you do that to Rossweisse!?

Doom Slayer:. . . . . . . . . . . .

Shitsei:Answer me!

Doom slayer continues to remain silent as his left hand grabs something from behind him and he brings it up, a holographic image appears showing an image of union not just that but below the screen a cash praise is shown "1,000,000,000,000,000,000,000,000,000,000,000" meaning that his because

Everyone:What the!? Union got a bounty placed on it and all its students!!

Doom Slayer: *nods before shutting off the holographic image*

Rias:Than that means your here to—

Y/N pressed another button on the devices and he tossed it to the ground has multiple holographic screen appear all showing different students, teachers and even headmaster all being killed by Y/N

Gasper:What? *looks at Y/N in fear* Why!?

Shitsei:How could you Y/N weren't you one of us!

A growl can be heard coming from Doom Slayer as he reloads his gun and aims it at his new opponents

(A/N:Start song now)

Rias:Everyone attack!!

Before they could react Doom Slayer already began to fire at the devils forcing Rias to quickly summon a force field to protect herself and the others from the bullets but when she saw Y/N charging at her she could see yellow energy surrounding him

He charged forward and collided with Rias force field destroying it allowing him to hit Rias and send her flying back crashing into her throne and then the wall who ding the eyes of Asia and Rossweisse who has awoken

Asia:Y/N!?

Rossweisse:Everyone be careful!

Shitsei, Akeno, Gasper and Kiba all move away from Doom Slayer but Xenovia and Koneko staid as the blue heard swordswoman tried to slash Y/N with durandal but he blocks her sword with his gun and then blocks Koneko's punch with kick surprisingly making a small shockwave 

He then uses the weight of Durandal against Xenovia has he moves out the way making her sword start going towards Koneko who moves out the way but gets punched in the stomach by Y/N laughing her out the club house

Xenovia:Koneko! Grrrr you bastard!! *goes to slash him again*

Using his blade gauntlet he blocks Xenovia first swing but she doesn't stop she continues to send numerous slashes at Doom Slayer who clashes with his blade gauntlet but with his hand he fires at the others

Kiba quickly summons two swords blocking the bullets with incredible speed, Shitsei is trying to dodge the shots but some bullets are able to leave scars on him, Akeno used her own barrier to block the attacks and Rias used her force field to protect Asia, Rossweisse and Gasper

Xenovia: HAAAAAAAAA!!!! *continues to clash with his blade gauntlet* why won't you fall!!

Swinging one strong slash that collides with the blade gauntlet sends a powerful shockwave the pushes the peerage members back a bit as Xenovia on the other hand could only look surprise of the nothingness she has done to Y/N

Xenovia:What?

Without giving her a chance to react Doom Slayer back hands her with his gun throwing her to the ground before pouring his rifle at her and while she was about to die Kiba quickly sprung into action and lock blades with his blade gauntlet has Dom Slayer began to fire at Kiba who lock his feet on the ground and block the shots

Shitsei decided to help so he lunged towards Doom Slayer with his left fist railed back as Ddraig's voice can be heard

Ddraig:BOOST!BOOST!BOOST!BOOST!

Shitsei:Take this!

While he attack Akeno also decided to attack has she fires an electric boat at Doom Slayer at the same time Shitsei tries to land the punch so Doom Slayer catches Shitsei fist and then moves the pervert in front of him allowing Akeno's attack to hit him and not Y/N

Shitsei: *getting shocked* W-W-W-W-H-H-Y!!!??

Akeno:Oops~ sorry~ oh?~

She sees Shitsei body being tossed towards her like bullet so the pervert crashed into Akeno and they are both send crashing into a wall

Rias:Shitsei! Akeno!

(A/N:Is still funny heheheh)

Doom Slayer shoulder cannon sees Kiba trying to surprise attack him from behind so it begins to open fire at him making Kiba dodge as he could not get close to Y/N

The shoulder cannon sees him stop and the knight is then force to block the bullets not because he wants but because a surprised Xenovia was behind him

Seeing him distracted Doom Slayer waisted no time and reloaded his gun quick before firing a bunch of bullets at Rias who held the force field to protect three of her members

Rias:Rreaaahh I can't keep this force field up *looks at Rossweisse* how are you feeling Rossweisse

Rossweisse:Do not worry Rias I can still ggrrag

Asia:No you can't your still very injured from your previous fight with him

Gasper: *still scared but decide to pull off a brave face* Rias when I tell you I want you to power down the force field

The three girls:What!?

Asia:What are you thinking Gasper!?

Gasper:I'll hold him in my time stop and you Lady Rias will attack him with your power

Rias:Yes that could work alright tell when your ready

What they don't know is that while their plan is good they forgot that Doom Slayer could hear them

Doom Slayer: *mind* They know I can hear them right?

Thinking of surprising them Doom Slayer continues he assault of bullets while the shoulder cannon kept Kiba busy but after a few minutes the gun runs out of bullets

Gasper:Now!

Rias lowered the shield and while Gasper was about to use his sacred gear a slot open on the side of Doom Slayer's gun has mini missiles were fired and send directly towards Gasper who's widen as a point blank explosion hits the four devils

After the explosion Rias could be seen on the left side of the room, Rossweisse was still in the spot were she had landed, Asia was on top of her and Gasper was at the back right of the room burned his face not recognizable and destroyed with only one eye still visible

Gasper: *raspy voice* ggaaauhhragh Ria—guh!

A foot stomps on his chest as his only eye looks up to see Doom Slayer looking down at him while pointing at his head with his combat shotgun

Gasper:Y-

"BANG!"

Kiba and Xenovia run in through the smoke and see this they're eyes widen in shock and tears could almost be seen

"BANG"

Doom Slayer: *mind* One more shot just to make sure

Kiba/Xenovia:Y/N!!!!!

Doom Slayer: *pumps his shotgun*

Quickly turning around he fires a shot at Xenovia who blocks it but gets pushed back a bit but Kiba took this has a chance to strike as he dual worlds his swords towards Y/N slashing him a bunch of times at his chest armor before finishing it off with an x shake slash which sends a shockwave that pushes Doom Slayer a little to the wall with no damages

Kiba:What? How could you!?

Before he could react Doom Slayer kicks him in the face sending him skidding back to a wall before turning his attention towards Xenovia who enlightens her sword sending an air slash at Y/N who charges at her diving under the the attack he pumps his shotgun and quickly gets up as he fires two shots at Xenovia who uses her sword to block once finishing that she quickly tries to slash him but he counters with his blade gauntlet than aims his Shotgun at her stomach and his shoulder cannon at her face and so

"BANG!"

"MULTIPLE BANGS!"

Xenovia gets molted by bullets from two different directions as her now faceless body falls to the ground dead making Rias's peerage lose another member

Rias:Xenovia!!

Gaining his attention Doom Slayer turns to right and sees Rias struggling to get up but once the devil girl sees her mistake her eyes widen as she sees the doom slayer pump his shotgun ban slowly make his way towards her

Rias:Nonononono please Y/N we can work something out

Doom Slayer:. . . . . . . . . . . . 

Rias:Please! Y/N—

Rossweisse:HAAAAAAAA!!!

She's lucky as Rossweisse tackles Doom Slayer and takes him away from Rias and into the woods where she releases him in the air as Y/N lands on the ground in an open field

Rossweisse:I will not allow you to kill anymore of my friends! *summoning a spear*

Doom Slayer: *puts away his combat shotgun and appears his blade gauntlet as he gets in a stance*

Rossweisse glares at her opponent before lunging towards them

Doom Slayer jumps back dodging the spear thrust from Rossweisse as her attack hits the ground making creator finding this as a chance to strike Doom Slayer lunges forward to stab Rossweisse who blocks his attack and tries to slash him but he blocks her attack and while she tries to punch him he counters with his own punch making putting them both in a locked position to see who comes out on top

Rossweisse:Ggrrrrrrrr

Doom Slayer:. . . . . . . . .

Rossweisse:Grr *grits her teeth* why must you do this huh? why could you just leave us alone

Doom Slayer:. . . . . . . . .

Rossweisse:Why can't you just tell us!

Doom Slayer having enough of her banter Headbutt's her and then kicks her back but she quickly takes flight and summons many magical crest behind her

Rossweisse:If you won't tell me then die!

Doom Slayer sheaths his blade gauntlet and brings his super shotgun

Firing his grabbling hook to the right it attached itself onto a three as it then pulls him towards the forest before Rossweisse many blast hit we're getting once was

And so seeing where he had gone Rossweisse aim her crest towards the forest he disappeared to before disappearing then as she summons a spear and flies into the forest

Where Doom Slayer hides behind a tree has Rossweisse herself flies passed him but this doesn't make him get out the woods yet a figure dashes towards Doom slayer with their fist

Y/N duck down allowing the person to hit the tree breaking it in haft seeing this he points his super shotgun up and fires at the person who blocks the shots and then jumps away from him landing a few feet away from was Koneko in her Nekomata form

Koneko:Now you made me angry Y/N

Doom Slayer:. . . . . . .

Koneko fires a blast at Y/N who rolls out the way as he fires his hook at Koneko who dodges it but then sees Doom Slayer getting pulled towards her he lands a strong punch her

Koneko blocks it but was send flying to tree which she stands on it before boosting herself towards Y/N her right fist ready while Doom Skayer was about to shoot her he spits a spear heading their way so he catches Koneko fist which dies push him back a bit and intervenes with the spear with a shot from his Super Shotgun

Rossweisse appears in battle and she like Koneko is not looking very happy as she charges at Doom Slayer who uses Koneko to hit Rossweisse stoping her charge as both girls fall to the ground and seeing this Doom Slayer decides to change weapons

His minigun

Doom Slayer:Rip and *the minigun starts to spin* tear

Rossweisse: *eyes widen* Look out!

She pushes Koneko out of the way shocking then nekomata as she sees her Sensei and peerage member get filled with bullet holes

Koneko:Rossweisse!

Doom Slayer stops as Rossweisse body falls dead to the ground

Koneko now enrage lunges towards Doom Slayer who lets go of his minigun and catches Koneko throwing her to the ground before he repeatedly starts to punch her in the face each time making it bloody  before his fist literally goes through her face killing now a fourth member of the peerage

Finishing her off he looks at his left fist seeing it all bloodied up from the kill but he doesn't care as he stands and puts his minigun away but then his attention is taken when he sees a lot of swords stab to the ground turning around he sees a pissed off Kiba holding his balance breaker sword

Kiba:You'll pay Y/N you'll pay!!

Doom Slayer:Rip *takes out his chainsaw*

Doom Slayer: *turns it on* and tear

Kiba:I'll kill you!!!

Kiba lunges towards Y/N taking one sword from the ground as the two clash with one another but once the sword made contact with the chainsaw it immediately broke but his balance breaker one didn't so they push each other back before lunging towards one another and clashing again only it then turns to rapid slashing from the boys

Doom Slayer swung his chainsaw at great speeds and Kiba swings his balance breaker sword very quickly that is until the knight unleashed black flames from his sword making Y/N jump back a bit allowing Kiba to grab a huge sword

Lifting it up he tried to crash a house on Y/N but his chainsaw cuts right through the sword before blocking another slash from Kiba but suddenly both warriors jumped back as a Thunderbolt crashed in between them

Doom Slayer looks up and sees Akeno in the sky both her fallen angels and devil wings are out and she's looking down at the slayer with tears on her eyes and anger spread around her face

Akeno:Die!

Akeno fires another lightning blast at Doom Slayer who jumps out the way dodging the attack and then blocks Kiba slash before he has to block another lightning blast from Akeno

Doom Slayer: *mind* I must cut Kiba down first before shooting down Akeno

Doom Slayer quickly sitting up his plan dodges another lightning blast by dashing to right has he then dodges a double thrust from both of Kiba's sword this gives him the chance to quickly cut off both off Kiba's arms in haft

Kiba:Aaaaaahhh!!!

Akeno:Kiba!

Akeno was about to fire another blast but she then sees bullets heading her way so she is forced to dodge them with quick flying maneuvers

While she focus on that Doom Slayer focus on Kiba who was still screaming in pain until Doom Slayer decided to end his misery

Cutting in haft with his chainsaw Kiba's upper body and lower body fall to the ground dead

Akeno above dives down towards where she was firing blast at Y/N but her eyes widen and her tears keep coming once she spots Kiba's corpses

Akeno:NOOOOO!! *starts to channels a power Thunderbolt* DIE Y/N

"BOOM!"

Before she could even fire the thing a missile or red orb hit her directly stoping her from even finishing up her attack as down below with Doom Slayer we see him wielding one of his many rocket launchers

He sees Akeno falling to the ground so he fires another missile at her making her body explode and go in many directions killing off another member of Rias peerage

Shitsei:BASTARD!!!!

Charging in at Doom Slayer who quickly jumps back and fires a pint blank missile at Shitsei who was in his balance breaker

But out the smoke Shitsei still was able to land the punch on Doom Slayer sending him flying back

Shitsei:I'm not done!! Dragon shot!

Firing a red blast at where he is the thing actually hits Doom Slayer creating an explosion that covers where he is

Shitsei:That's payback you fucker 

To his surprise four green orbs pop out of the smoke and hit Shitsei the surprising thing is the bullets hurt has hole could he seen in his armor

Shitsei:Raaagh what the heck was that!?

Ddraig: *in his mind* Shitsei you must be careful the opponent you face now is not ordinary nor is his exactly to be underestimated

Shitsei:Then I'll just have to transform into cardinal form

But before he could even do anything a grappling hook pops out the smoke and hooks on Shitsei making look on ahead and sees Doom Slayer getting pulled towards him with his super shot gun and the BFG 9000

Doom Slayer:RIP AND TEAR!!!!

Before Issei(A/N:just this once since he's going to die)could even do anything Doom Slayer knees Issei in the face making him fall down onto his back as Doom Slayer begins to repeatedly shot the chest armor slowly breaking it

Shitsei:Hey get off me

Doom Slayer fires his face with his super shotgun cracking it a bit making him turn the BFG 9000 to his face has he fires two green which destroy his helmet

Issei: *nervous* Ooooh hey Y/N-

Y/N let's go of both his weapons and kills Issei

Splitting his head in two

After killing Issei the balance breaker begins to disappear into red particles has it only leaves the dead body of the teenager

But then Doom Slayer sees a green orb pop out off Issei dead corpse abs begin to fly away that is until Doom Slayer captures the green orb in a spherical ball that has reading on it

Doom Slayer: *mind* no more innocent people will die in your idiotic battles with Albion Ddraig

After that Doom Slayer puts both his guns away has he grabs the hilt of a weapon that's attached to him

Lighting up Crudicle the light coming from the weapon shine bright as Doom Slayer still has two more targets left

With said targets Rias and Asia waited patiently inside the club house as we see Asia mourning over Xenovia body while Rias stood at the entrance waiting for her friends to return but her eyes become shocked when sees him

Rias:No nonononono NO!!

Appearing her devil wings Rias charges at Doom Slayer her aura surrounds her entire body

Rias:Takes this!

Unleashing her power of destruction she fires a blast of destruction towards Doom Slayer who walks

And while walking he easily destroys the blast with a slash from his sword destroying the attack completely

Rias:Grrrr I'm not giving up!!

She creates two spherical orbs of destructions and fires them at Doom Slayer which ended as the blast has he cut them both

After he poor attempts his shoulder canon shoots Rias landing shots at her right leg, left wing and right shoulder making screaming in pain before landing on the ground on one knee

Doom Slayer now stands in front of her his lightsaber (A/N:We all that's just an anti demon lightsaber) placed in front her neck

Rias:Please Y/N *tears start to fall* spare me please I'll do anything! I'll give you anything! I'll even give you my body! please just spare me!!

Doom Slayer:. . . . . . . . . . . . No

(A/N:Music stops here)

With one slash from his lighten blade Rias head falls to the ground and her body falls limp to the left

Doom Slayer has now just killed the king the only thing left is the bishop

Speaking of Asia we see her still kneeled on the floor in front of Xenovia's corpse that is until she wipes the tears after hearing footsteps approaching

Asia: *turning around* Rias how it—

"BANG!!"

Asia body gets send flying back towards the end of the room as we see Doom Slayer standing there with his super shotgun raised before lowering it down as in his hud a list of names appear

Does are the names of each union student he wants to kill and now he marks off Rias, Shitsei, Akeno, Kiba, Xenovia, Koneko, Rossweisse, Asia and Gasper

After that he simple turns around and walks away leaving the corpses of the O.R.C to rot

K.O
