(Sachi's Dream)(Sachi's POV)

I woke up, looked around and to my shock it was the cave where I died along with the Moonlit Black Cats and Yui was here with me she was scared.

Yui: mama where are we?!

Sachi: why here!? Of all things!!

Y/n: WHY DO YOU HAVE TO DIE SACHI!?

Sachi: Y/n!?

Yui: papa?!

Y/n: DAM YOU KAYABA AKIHIKO!!!

Then we were teleported to the 100th floor the final boss where Y/n defeats Kayaba Akihiko but Y/n was not the same.

Sachi: Y/n?

Y/n: dam you Kayaba Akihiko!!! You killed Agil, Argo, Klein, Silica, Lizbeth, Keita, Tetsuo, Sasamaru, Ducker, Asuna, Yui and my first crush Sachi!!

Kayaba: I'm sorry what I did!!

Y/n: sorry won't bring them back!! I'll avenge them!! Goodbye Kayaba Akihiko!!

He transforms into Diabolic Esper form with his demonic powers and began to stab Kayaba with his claws. Blood came out of his stomach and chest then Y/n rips the final boss's head blood was covered in his clothes, the white hair and his face. The both of us were shocked, scared what he did and he began to laugh for a few seconds he began to regret his actions.

Y/n: No this isn't what I wanted!!

He grabs his head screaming in pain, Sachi rushes towards him but it was too late as she was pushed back and he transforms into his new form......

Mad Paradox.

Y/n:.....

Sachi: Y/n?

Y/n: HAAAAAAAAAA!!!

(SAO and RWBY Dream)(Nobody's POV)

Asuna: what the?

Sinon: Hello is anybody here?

Suguha: hello?

Lizbeth: Girls!!

Silica: where are we?

Alice: i don't know!!

Emily: do you hear that?

Kureha: yeah that sounds like Y/n.

Ruby: yeah it got to be him!!

Zeliska: let's find him.

Kiriko: I think I found him!!

They all went towards him but sees Sugou Nobuyuki in his ALO avatar, PoH, Shinkawa Shouichi(Death Gun) all the people that Y/n fought in the past were cowering in fear as they saw Y/n brutally killed Raios and Humbert.

Shinkawa: what the hell are you!?

Then Y/n transforms into his Devil Trigger but it was incomplete even his teeth was different.

Y/n: The Devil's and the Goddess's son and I'll make sure that all of you won't be killing anyone for good!!!

One by one he rips them apart, eating their flesh, their organs as blood sprayed on his clothes, hair, hands, teeth and his face.

Blake: oh my Oum!!

Medina: master Y/n!!

Shouichi: please we beg of you!!

Y/n: BeGgInG wOn't SaVe YoU!!!!

He claws out Shouichi causing him to scream in pain. The SAO villains runs away but Y/n uses shadow clones and they all chase them down. Began to rip them apart, eat, stabbing them, burning them, whipping them, beating them to death.

Pyrrha: what the....

Yang: hell!?

Nora: Y/n you're scaring me!!

Y/n: so many pathetic souls, so little waste of time*dark chuckles*.

Weiss: Y/n what's wrong with you!?

June: can he even hear us?

Ren: I don't know but I don't like his chuckles.

His eyes glowed white and then red. Y/n uses his flame powers and burns the corpse turning them into ashes and the wind blows them away to the air. Y/n went to Vergil's Devil Trigger and summons Yamato.

Y/n: scum...

They were about to take out their weapons but Y/n passed them. They couldn't move until Y/n puts away Yamato and went back to his demon form, as blood came out of their chest. They screamed in pain as Y/n puts away Yamato.

Sinon: AHHHHHHHHHH!!!

Y/n: "Foolishness, girls. Foolishness. Might controls everything - and without strength, you cannot protect anything; let alone yourselves."

Coco: Y/n why are you doing this!?

Velvet: we're your girlfriends!!

Neo:*whimpers*

Summer: why?

Y/n: this is my path to kill anybody who is a threat to my goal of peace even means of killing my girlfriends.....

Cinder: Y/n....

Raven: dammit, it's no use. He's gone now...

Y/n: I NEED MORE POWER!!!

He stabs both Yamato and Rebellion to awaken Sin Devil Trigger the final form of Devil Trigger.

Suguha: brother.

Kiriko: why?

Y/n: Goodbye my lovers I'll be seeing you once the evil is gone for good...

Then everything went white...

(DXD Girls)

Rias:*groans* what the?

Izumi: Rias are you okay?

Rias: yeah where's the others?

Asia: we're here Rias.

Xenovia: where are we?

Irina: I don't know but I think we're in.....

Sona: Hell!?

Tsubaki: yeah but the flames are now blue.

Kiba: let's check that castle over there!!

They went into the castle and saw human female souls doing work like cleaning, cooking or basically anything.

Rossweiss: who ever taken these souls is a monster!!

Then they arrived at the Throne room and they all saw Y/n sitting on the throne of hell.

Vail(fem): Y/n!!

Kuroka: why are you doing here!?

Y/n: this is my home, this is where I belong in hell.

Koneko: but I thought Devil May Cry was your home!!

Y/n: yes but I gave up on that dream, heroes have to follow rules while villains don't have to follow rules. Us demons and devils don't get friends or love, we only get hated one which fuels our abilities and I'll kill the gods and rule the universe with the power to control everything within my hands!!

Rias: but we're your girlfriends!!

Y/n: true but your father banished me from ever seeing you so I killed him and your sister she begged and I understand so i let her join my ranks.

Venelana: monster!!

Y/n: monster? No I'M THE DEVIL OF HELL!!

Raynare: WHAT!?

He uses his electric abilities and shocked them stunning them.

Akeno: why!?

Y/n:*dark chuckles* I'm tired of following rules restricting me of doing bad things my demon side agrees and I prison my angel side making him depressed that I killed my family in cold blood it was like music to my ears.

Y/n: you all bring pleasure because I'll be breeding you all of my sexual pleasure~

Rias: this isn't you!!!

Y/n: no this is my true self!!!

(Lucifer's Dream)(Lucifer's POV)

I was woken and I gotten up, looking around was nothing just endless fields of water.

Lucifer: where is everyone?

I walked, nothing was here, no life, nothing until I saw a tree with a person on the ground. I rushed towards him but I slow down that it my son and he was in his angel form.

Y/n: why father why don you have to die!?

He began to tear which broken my heart seeing my new lover in tears.

Y/n: dam you Siralos, dam you Fumas, dam you Satanick!!!

He begins to slam his fist down to the ground repeats it causing it to crack into pieces and Y/n's hands began to bleed.

Y/n: why do you have to take my lover away?

Then his hair grew longer, his skin was turning dark blue with lighter blue lines and his clothes changed. Now I was in tears my lover is now a fallen angel.

Y/n: I've now become a fallen from grace and no longer be with my lovers. They all died from them and I'll kill all the gods who takes my lover's lives away!!

I was shocked what I heard from Y/n. He'll now kill the gods I tried to stop him but it fazes through him. He walks away and vanished away, I scream on the top of my lungs then I blacked out. Then i heard him laughing it was full of evil within him.

Y/n: HAHAHAHAHAHAHA!!!!
