3RD PERSON POV

Ajuka: Devils! Everyone!

Ajuka announces to the devil army as they all gather around him.

Ajuka: Today is a new day! We the devils have been pushed back for far too long because of AAU! It's time we-

*SLICE*

All the devils stare in shock as the halves of Ajuka fall to the side, revealing someone in a suit of armor wielding the crucible.

Vega: Good job. Now time for phase 2 out of your thousand ways to kill-

Devils: I'LL KILL YOU

Vega: Power level is low compared to the many big threats you faced in the depths of hell. Fight to your heart's content Doom Slayer.

RIP AND TEAR

The doom slayer wields his crucible and chainsaw, running towards the devils as they all fly to his angered.

Later

TIME HAS STOPPED

Y/N charges with Murasama alone, slaughtering the devils who tried to attack Vale in a massive wave only to fail due to their defenses.

Y/N: So easy!

Sirzechs: SOMEONE KILL HIM! DON'T CAPTURE HIM JUST KILL HIM!

All the devils rushed at Y/N, firing their demonic powers as Y/N dodges them all, even using Water Streaming Rock Smashing Fist to deflect many of them back at the devils. Swinging his sword, he creates a massive shockwave that slices through the thick of the devil army and easily runs while slicing apart many of the devils that come close to him.

Y/N: *mock* Just surrender and I'll show some mercy! Like it's not that har-

He dodges an incoming projectile before grabbing a sword from a nearby devil and stabs it through a rook, killing her.

Y/N: I SAID SURRENDER FOR FUCK SAKE!

Riser: You....YOU'LL PAY FOR KILLING MY PEERAGE!

He fires off fireball after fireball, exploding the battlefield more and more as he unintentionally kills off more of his peerage in the process. He doesn't care about this though, as he was so hellbent on killing Y/N he never paid attention to his back.......

*GRAB*

Riser: HUH?! LET GO OF- OW OW!

*RRRRRRRIIIIIIPPPPP*

IMMORTALITY SEVERED

Riser: M-My arm! H-How!

His other arm was ripped off along his tongue, rendering him unable to speak properly. He looks up in terror to see Y/N holding his fist back....ready to end his life when another devil stops in front of him.

Ravel: P-Please d-don't hurt him! H-He's my brother!

Y/N: Your brother is responsible for the massacre at several Union cities and is already claimed to have sexually assaulted many devils and such! This is war so step aside or I won't be so merciful!

Ravel: H-He's my brother.....he's family........

Y/N: I.....

Y/N reluctantly backs off seeing her tearing up as he Riser but not before leaning into her ear.

Y/N: *whisper* If he attacks me I'm killing him.

Ravel: Ok I-

*SPLATTER*

Ravel: *cough blood* B-Brother w-why......

Ravel holds her hand to the hole on her chest, showering Y/N with blood as Riser held his hand out.

Riser: You foolish sister! I don't need the likes of-

*BOOM*

Y/N crushes his head instantly and turns to heal Ravel just in time to receive a ball of energy to his face.

Y/N: Is that supposed to do shit?

Rias: I-I AM RIAS GREMORY! OUR NAME WILL NOT BE DESTROYED BY THE LIKES OF YO-

*STAB*

Rias eyes widen.......and her body stiffens as Y/N removes the knife from her head.

Y/N: You don't know how much I wanted to do that.

She falls.....dead as a door nail while Sirzechs watches in disbelief.

Sirzechs: You......YOU BASTARD!

He fired a barrage of power balls at Y/N who effortlessly flicks them away, not even bothering to try at all.

Y/N: Ok this is getting boring.

Sirzechs: JUST DIE ALREAD-

*STAB*

He coughs blood as he finds an arm through his chest. Not yet finished however, he screams while activating his fleeting energy and tries to erase Y/N from existence only to fail as Y/N grabs his neck.

Y/N: Die

*CRACK*

He drops his corpse onto the ground before incinerating it much to the horror of Riser's and Rias's peerage. He turns though and offers a hand, confusing them until he speaks.

Y/N: You all suffered at the hands of your own masters....forced to become servants.....just like me. If you comply, you can come to AAU alive and well....that is if you don't attack me or any AAU forces.........

Yubellena: I-I accept.....

Kiba: Me too......

Y/N: *grin* That wasn't so hard was it?~

They all quickly crossed the portal to go to Nevada before he closes it as he tosses Ravel into there.

Kuroka: Is my sis ok?

Y/N: Yeah....she went with them....

Kuroka: *looks around* I never thought the great Lucifer could be killed so easily.......

Y/N: Wasn't he partially responsible for your experimentation?

Kuroka: Yeah......But thanks by the way.

She hugs Y/N as he reaches down to scratch her ears.

Kuroka: *purr* Nya~ Keep doing that~

Y/N: I really need to fight no-

Kuroka: Maybe we can have little kittens together~ Take me in bed and poun-

Y/N: *horrified* No absolutely not. 'I don't want another Esdeath!'

He lets go of her and runs off into the distance with Kuroka following him and Vali close behind.

Vali: 'Kuroka you idiot....don't be so horny all of a sudden!'

Albion: Agreed.

Kuroka: Y/N come back~

Y/N: NEVER!

Later

Y/N: *sweating* I.......underestimated you big guy.....

Y/N stands before the doom slayer while looking around to find the corpses of a few hundreds of thousands of devils....,

Vega: Serafall and several other high-ranked devils surrendered. Their forces are now rendered down to 20% and are residing in Union territory

Y/N: That's good. I'm presuming the slayer took care of everyone?

Vega: He is disappointed but is glad he could go all out for a hit. Innocent lives have been covered for. Another short mission....

Y/N: True....let's head back now!

Doom Slayer opens a portal before heading back with his transmitter.

Y/N was also about to teleport back until Kuroka jumps on him.

Y/N: GET OFF ME WOMAN!

Kuroka: Nya~ Why?~ Embarrassed that you'll get caught?~

Y/N: YES AND I'M NOT INTO THOSE KINDS OF STUFF!

Kuroka: Bear me kittens Y/N~ And I shall not bother you agai~

Y/N: NEVER!

Kuroka merely giggles as she latches onto Y/N as they both teleport away, leaving the entire devil army in shambles......divided and conquered.

Vali: WHY?! I JUST ARRIVED!

Albion: Just use the transmitter and go to them partner.
