In front of the school we see the knights taking on Kokabiel as he battles all of Eric's knights and sending them all flying. One knights charges towards him ans swing his sword at him but he dodges it and slash at him and then stabbed him as the knight collapse onto the ground. Kokabiel looks around to see most knights defeated while some dead as he begins to laugh.

Kokabiel: (smirk) Is no one strong enough to face me in battle?

Suddenly a bullet flies by which Kokabiel immediately dodges it. He looks over to see Y/n aiming his pistol as he said.

Y/n: So you must be Kokabiel Huh? Well hope your ready because I'm gonna end you just like what I did to your science friend.

Kokabiel: (smirk) You? Your gonna try and stop me? Ha! Do you honestly think you, a Dark Slayer can stop me? Don't make me laugh.

Y/n: Well either that who I'll let them fight you.

Suddenly a bolt of lighting hits Kokabiel as Akeno qnd the others came over as Kokabiel blocks her attack.

Akeno: We got your back Y/n.

Issei: Yeah this dude is toast!

Y/n: Let's end this quick so we can get along with our lives.

Rias: (smirk) I couldn't agree more.

Kokabiel summons two of his holy spears only for Xenovia and Kiba to come down ans clash of him. Both Xenovia and Kiba clash at Kokabiel while Y/n pulled out his spear and then open a portal beneath him as he drops through.

After Kokabiel pushes the two back Y/n came out of the portal behind him and swing at him but Kokabiel blocks his attack. But Y/n opens another portal behind him and he goes through and out and slash at him.

Kokabiel stumble forward but he turns around and goes for a swing when Koneko leaps over Y/n and kicks Kokabiel in the face which sent him sliding back far.

Y/n: (smirk) Nice punch Koneko.

She nodes while Eric rush by and begins to clash blades at Kokabiel as the two dual as Eric dodges and blocks Kokabiel's attacks and he kick him but as he spin around and slash at him which Kokabiel stumble backwards and a bit of blood came out of his cheek.

Eric: Leave this place now Kokabiel! You have no reason to be here!

Kokabiel: You don't tell me what to do! I will begin this war and no one isn't going to stop me!

He then fired a blast that cost everyone to move out of the way very quickly and once dodged Xenovia charges towards Kokabiel and try to swing at him but he fire a blast that sent Xenovia flying and she crashes onto the ground.

Xenovia slowly gets up while the others were ready as Kokabiel then begins to laugh.

Kokabiel: (smirk) I can't believe you all still keep on fighting! Even though without your masters you all don't stand a chance.

Y/n: Masters? The hell js that suppose to mean?

Xenovia: Answer us Kokabiel! What do you mean by that?!

Kokabiel laughs once more leaving everyone confuse as Kokabiel continues to laugh. Then he finally stop and then tells them with a smirk.

Kokabiel: (smirk) I suppose Eric here didn't tell you did he? Well then I suppose I will tell you.

Eric: Kokabiel don't!

Y/n: Why? What is this big secret?

Eric: You don't want to know!

Kokabiel: (smirk) Surely they must know.

Eric: No!

Kokabiel: (smirk)......The truth is during the war many years ago God and all four King devils!

Everyone is shocked by this while Eric slowly forms a fist in anger that Kokabiel told them this secret.

Xenovia: (shocked) What?! God is dead?! It can't be.

Rias: Your lying!

Kokabiel: (smirk) Which I was but no. God was killed millions of years ago along with all four Kings devils. After the war they decided to end the war even though it was close to a victory. With God dead the high ranking angels along with high ranking devils take leadership of both hell and heaven, promising to never go to war apon each other ever again.

Eric: He's telling the truth. My ancestors also knew about this but we kept this secret because if anyone would find out, it would be bring Chaos and destruction apon both worlds. Right now Michael is taking in charge of heaven and answering peoples prays. I'm sorry.

Then Asia collapse from shock which Koneko catches her while Kokabiel goes on to say.

Kokabiel: And now you hear the truth and my reasoning for why I want this war to continue. Try to stop me all you like but I think you all are too shocked to even fight me?

Everyone was in disbelief by this and wasn't sure what to do. Everything was silent as nowhere spoke or say. Then seconds later they hear laughter and it was not from Kokabiel but rather from Y/n as he laughs for a while which made Kokabiel confused and stunned.

Kokabiel: Why are you laughing?!

Y/n: (chuckle) Because I really much suspect something more but that's it? God is dead! I mean yeah it's a surprise but really? Does that really stop me or anyone? Please.

Kokabiel: (angry) You cannot be serious! God is dead and your not bother to the fact that all of your beliefs and everything you thought are no more! What the fuck is wrong-

Y/n: I'm no worshipper to god! Not even close. I follow my own beliefs and my own goals. If anyone is gonna try and stop me then so be it. I'll take them all on because no one will not mess with the people I care for.......Well except for Issei, anyone can mess with him.

Issei: Hey!

Y/n: (smirk) Point being. If you think that truth is going to stop me? Your dead wrong.

He immediately transform into his second armor as he pulled out his sword from his back as Xenovia is disbelief the power he is given off including Kokabiel.

Kokabiel: Your making a big mistake here?!

Y/n: No. The only person who is making a mistake is you. Harming Irina, trying to destroy my school, hurt my friends beliefs. I'm gonna make sure your never gonna flap your wings ever again.

Kokabiel steps back and immediately spread his wings try to slash at him but quickly Y/n appears behind him and immediately his wings was cut off as Kokabiel yells in pain. Y/n turns to him while Kokabiel glares at him and he try to swing at him but Y/n blocks his holy spear and then breaks it.

He walks towards him and breaks the other holy spear that was about to slash at him. Kokabiel charges towards him but Y/n grabs him by the face and slammed him hard onto the ground. The impact cost a blast and a large crack to form on the ground.

Then Y/n picks up Kokabiel by the throat as Kokabiel struggles to breath but then Y/n throws him across and Kokabiel lands on the ground. Y/n casually walks towards him while Kokabiel fire his last holy spear but it bounce off of Y/n which made Kokabiel more afraid as he ask him.

Kokabiel: What the hell are you?! Are you some sort a god or something? If so....what kind of a god are you?!

Y/n approaches Kokabiel and then he grabbed him by the neck once more and lifted him up in the air and he tells him.

Y/n: God? I have no desire to be God. But if you must know, I'm the one who kills assholes like you who try to harm countless of innocent lives. Now.....enjoy whatever your piece of shit soul goes to.

He then drops him to the ground and before he can do anything Y/n slice off his head. His head rolled away while his body drops to the ground. Y/n looks down at his body while everyone is relieved that it is all over.

The enchantment dorm that Sora and her group made disappeared with Y/n turning to everyone and says.

Y/n: You know you all could helped me right?

Issei: How should we suppose to know? You got everything under control.

Y/n: Yeah but I was suspected for Xenovia to get her payback for Irina. Either way doesn't matter, he's dead anyways.

Rias: Well at least that's good.

Y/n changes back and he looks over to find Eric but he was  gone including his knights as he thinks they just return back home. Y/n move his neck a bit while he walks back to everyone else and tells them.

Y/n: Hey if I'm late or haven't shown up to school tomorrow, then it means I might be sleeping. I mean for real what time is it?

Akeno: It's almost morning.

Y/n: Seriously?! Well I'm definitely skipping school so I can get some sleep.

Rias: (giggle) Bet you do.

Kiba: Everyone.

They all turn to Kiba as he then bows and tells them.

Kiba: I want to apologise for my actions. Please forgive me.

Y/n: (smirk) No need. Just glad your back.

Issei: Yeah never do that again.

Kiba: I promise.

Y/n: Well with that sorted I'm gonna take my leave, later my  people!

And so he left as he take his motorcycle bike and he rides home.

(Next day)

He takes the day off for school so he can get some sleep but after a while we see him on the balcony on the phone and talking to Eric.

Y/n: So you knew that God is dead this whole time? Why didn't you tell me?

Eric: (phone) I wasn't sure how well you can take it. Although your not phase by it I bet everyone is, especially Xenovia.

Y/n: What about Irina?

Eric: (phone) She's awake and......I haven't told her. No one doesn't want to.

Y/n: Make sense. So what happens now?

Eric: (phone) Right now we just relax and wait for another threat to show up.

Y/n: Right. Oh what about Freed? Did you take him?

Eric: (phone) No. I think he might have escape.

Y/n: Damn it. That guy is very creepy.

Eric: (Phone) You could have kill him you know.

Y/n: Yeah but I didn't have a chance.

Eric: (phone) Still I'm sorry for keeping this secret from you.

Y/n: (smirk) Nah don't apologise. It doesn't change who I am for the slightest.

Eric: (phone) Does nothing chance you?

Y/n: (smirk) Nope.

Eric: (phone) Well talk to you later, bye.

Once the call ended he heard knocking so he look down and to his surprise sees Xenovia knocking. Soon he let's her in as Y/n ask her.

Y/n: What brings you here in my fine home?

Xenovia: I needed a place to stay for a bit. Do you mean if I stay here?

Y/n: Um sure but don't you have Irina or the angels in heaven or any church.

Xenovia:..........

Y/n: What's wrong?

Xenovia: You see......

Then she reveal her devil wings to Y/n which surprised him as Xenovia then tells him.

Xenovia: I've abandon my place as an angel and I became a devil.
