We have arrived at school, Sona's peerage have already set up protective barrier.
Sona: we have surrounded the school barrier so anything happen in there doesn't effect anything in the outside.
Rias: I appreciate it Sona
Sona: remember it's only hold as long as nothing drastic happen.
Y/N: guess I can't go all out
Tsubaki then appear through the portal.
Issei: is Irina ok?
Tsubaki: she's okay nothing live threatening, she can thank Asia for that.
Y/N: any of you heard word from xenovia or kiba?
They all shake their head.
Y/N: very well then we'll handle this our self and maybe they will arrive in time.
Sona: It's not to late to contact your brother.
Rias: You know what I don't see. You trying to contact your big sister.
Sona: Sirzechs loves you, there's no doubt that he will come here if you call him so call him
Akeno: There's no need I've already contacted him he will be here within the hour
Rias: How could you do that with out asking me
Akeno: You know we can't do this on our own. Our enemy is a leader class Fallen angel he's not some one you can take on your own
Y/N: I'll take care of Kokabiel and his black knight you guys just focus with the priest.
Koneko: no Y/N!! You no match for both of them, y-you'll get killed
Issei: you realized who's our enemy is right?
I then smile at them, I ruffles koneko's hair
Y/N: don't worry I'll be fine just focus on the stray and what ever diversion that Kokabiel prepared.
Rias: Fine then, I guess this will be a fun hour
We walked through the barrier and into the new school building.
Rias: Issei I want you on support
Issei: Support?
Y/N: Yes, she want you to protect Asia and give them power when she needs it
Issei: I can do that
Rias: And Y/N
Y/N: Yes Rias
Rias: please be careful, I Know you're powerful but our enemy is not like something you have faced.
Y/N: Can definitely do that
Rias: Let's concentrate on being on the offensive for this one. We need to get into the school and prevent Kokabiel from releasing his power of whatever that may be. Unlike the fight with Riser our lives will be at risk this time
Y/N: the only one that going to lose their live today is Kokabiel and his goon
Issei: I feel like this won't end very pretty with him saying that
We walk out of the New school building and see a weird light.
Asia: What in the world is that?
???: It seems like the 4 Excalibur have been made into one. That is just Valper you know
We look up and see Kokabiel sitting on some sort of throne floating in the sky.
Rias: Kokabiel
Kokabiel: So is big brother on his way yet or is it Serafall instead
Rias: Right now we're the ones here ready to fight that's all that matters
Kokabiel then forms a massive spear of light and throws it at the gym building making it explode into rubble, leaving nothing there standing but the spear. The spear then disappear.
Kokabiel: This is boring, I need a diversion
Issei: n-n-no way No freaking way dude Then his left hand starts to glow and Ddraig speaks
Ddraig: [What's wrong kid you scared]
Issei: Of course I am, I've never seen a lance made of light that big before, it's like it's from another dimension
Ddraig: [Of course it's from another dimension. Look at it, we're talking about a man who survived fighting God and the Devil King]
Issei: Do you think we can still beat him?"
[When it comes down to it, A. I can turn most of your body into a dragon, or B. The young king over there do it on his own when he got really pissed]
Issei: Ohh I can kill Kokabial, wait young king?
Y/N: he's talking about me issei, its nice to meet you ddraig.
Ddraig:[same here my king, but I really wish we can talk in a better situation]
Y/N: then let's make the situation better, and by the way ddraig you don't need to turn that kid body. I can l handle this.
Issei: That's great
Kokabiel: Now since you came here to see me I'll let you play with my favorite pets
Then a light strikes down from his floating throne making a magic circle apperar. Then fire shoots out of the circle showing shadows of the monster inside. The monster steps out of the fire revealing it's self. A Cerberus, gate guardians of Hades.
Rias: bringing those creature to this world is forbidden. Koneko, akeno
Both: yes ma'am.
One of the heads of one of the Cerberus shoots a flame at Akeno but she freezes it with snow and cold air. Koneko then give another head a drop kick and kicks another head before jumping off of it. Then Akeno shoots lightning at it making it fall over. It gets back up roaring.
Koneko: tsch
Akeno and koneko is preparing to fight the Cerberus again, koneko Start to punch the Cerberus when she tries to jump off the beast she gets bit in the leg and thrown into another's mouth. She broke out of the dogs mouth and kick one of its eyes making it fall over before landing next to Issei and Asia.
Rias: Asia heal koneko quick.
A second Cerberus appeared and rush towards Asia.
Y/N: oh no you don't.
I rushed towards the second Cerberus and I punched the middle head of the Cerberus planting it to the ground killing it instantly. Then step forward and point my hand toward Kokabiel.
Y/N: where's my sister?
He then smiles maniacly.
Kokabiel: right there
I then feel the black knight coming from behind, I turn around to block it but before it hits me the swords is parried and a certain blue haired girl come to the rescue. The black knight then jumped forward making a space.
Xenovia: looked like you need a hand.
Y/N: I got most of it covered, but thanks for coming. Oh and if you're wondering about the Excaliburs you can ask the old man over there
I pointed towards valper and freed.
Another Cerberus then appears and charge towards issei, but before it can reach him many swords appear from the ground impaling it.
Y/N: you're late kiba
Koneko: so kiba how's your vacation?
Kiba: fine I guess
Rias and akeno finished their for with their power combo and now preparing to fight Kokabiel. Rias the then throw a ball of destruction towards Kokabiel,but he just slap it away.
Kokabiel: Impressive, look how much stronger you've become having a little red dragon emperor inside you, sexy, and fascinating as well.
Valper: it's complete
Valper is laughing maniacly
Kokabiel: Now I get to have the massive power that results from the combination of the swords that's our trade off. Sweet deal huh.
Valper: you better leave this place because in twenty second this area will be decimated.
I then activated my magic, my hands starting to change. Black scale is appear in my my hand and a black wing shaped aura Bagan to appear in my on my back.
Xenovia: Y/N you're a…
Y/N: I'll explain later right now both of you try to stop that stray while I deal with that black knight.
Kiba: Roger that.
We then charged together, the black knight is moving towards xenovia and kiba but I stopped him.
Y/N: your fight is with me.
I try to kick him but catch my feet and throw me. I managed to land but the knight run towards me, he then do a overhead swing I managed to catch the blade. I pull the blade towards me the deliver a strong kick in his stomach, I let go of the blade, charging my energy in my hand I punched him in the face sending him flying. I then looked at kiba and xenovia's fight and sees her… wait is that durandal? Damn I still remember when I get hit with that sword, it cracked my skin a bit.
I then looked at the Black Knight and he is holding his cracked helmet by one hand.
Y/N: hmm, still want to fight?
The helmet then start to fall apart and revealing...
Y/N: no it can't be!!
The person in inside the armor then looked at me with her blue eyes but something is wrong.
The fight then stopped as everyone looked at me and the knight.
With xenovia and kiba
Xenovia: no impossible
Kiba: please don't tell me who I think she's.
Xenovia then nod and looked at us.
Kiba: oh no
Rias and the rest of her peerage
Rias: Y/N what wrong?
Akeno: I think he recognized the knight.
Kokabiel: of course he recognized her, after she's his sister.
Asia: oh no
Koneko: Y/N
Back with me
Y/N: sister? Is that you?
She then looked at me her eyes began to let out tears.
Alice: brother…kill me…please…
Y/N: no…
I then took a few step back
Y/N:…i-i-i don't want to fight you
Alice: forgive…me
She then run towards me and starting to slash me. I block all of her attack
Y/N: sister please stop this!!
Kokabiel: hahahaha like the changes I made to her, human?
Kokabiel then appear beside her. While rias peerage is running toward us
Y/N: dammit what have you done to her?
Kokabiel: just a little brainwashing and I got this beautiful slaves.
He then start licking her face, it's agitated me even more.
Kokabiel: I must admit her mental resistance is great and you know what's the best part is?
He then step beside her and smiling like a maniac.
Kokabiel: she keep screaming your name until I broke her, ahh the sound of her screaming it's a music to my ear.
Then I snapped, I rushed towards him but she blocked the way I have no other choice but...
Y/N: forgive me sister.
I delivered a strong uppercut in her stomach making a hole in her armor. She then went unconscius in my arm.
Alice:b-b-brother…
Kokabiel is back in the air spreading his wing with a Sadistic smile in his face. I looked at him with my hate filled eyes.
Rias: Y/N are you...
Y/N: please take care of her,
Koneko then lift my sister and bringing her to Asia.
Rias: where are you going?
Y/N: getting rid of the pest.
I then summon two large black wing and start to fly.
Rias: be careful.
I then fly towards Kokabiel there he's waiting with a light sword in his hand.
Kokabiel: you're full of surprised human and i really impressed with your fight.
I charge my fist with an insane amount of energy.
Kokabiel: but in the end you're no match for me.
He charged at me swinging his sword, I dodged it and maneuver my self above him.
Y/N: for my sister.
I punched him so strong and make a large creater upon landing and a thick smoke. Through the smoke I see him, heavily injured but Alive. I land a few meter from him and stare him in the eyes.
Kokabiel: h-h-how…
Y/N: it's the second time you have anger me Kokabiel.
Kokabiel: w-w-what do you…, no impossible.
I then smirk seeing his terrified face.
Kokabiel: c-c-chaos!!! No please have mercy!! Please!!
Y/N: you know I was planning to let you live and deliver you to Azazel my self, but after knowing what have you done to my sister…
I then create a magic circle and focused all my energy there, my body is surrounded with violet aura marking that I have reached maximum capacity.
Kokabiel: no no noooo!!!
Y/N: dosvedanya
I unleashed all of my magic at him. A huge cloud of dust is covering where he was at and after the dust disappeared it show nothing but black feathers. I then sigh in relief. I jumped of the Crater See Rias, Sona and their peerage along with xenovia. I rush towards them and see my sister.
Y/N: sister!!
Rias: it's okay Y/N she's unconscius but she's okay. Thanks to Asia and akeno here.
Y/N: Thank you very much, Asia akeno.
I then bow toward them
Akeno: there's no need Y/N
Asia: yea no need to bow, its embarrassing.
Ddraig:[hahaha this is the first time i see you bowing Y/N]
Rias: ddraig?
Y/N: shut up you ddraig.
???: Impressive fight human.
We then towards the voice source and see a person with white armor.
Y/N:(Albion) so you have been watching?
???: I was ordered to take down Kokabiel and bring him to Azazel, but after seeing your rage it's seem futile to just go in then take him.
Y/N: you make a wise decision.
He then take the unconscius freed.
Ddraig:[are you ignoring me white one?]
Albion:[you're still alive red one, I have no interest to fight now but we'll meet again. We're meant to fight after all]
Ddraig:[haha very well white one]
The white dragon emperor then take of then disappeared to the night.
Y/N: seriously did you guys have to fight each other every time you met?
Ddraig:[(chuckle)]
Sona: Y/N I think it's time you explain to us who are you really?
Xenovia: yeah the way you fight Kokabiel, there's no a human can generate that much energy.
Y/N:(sigh) you guys really want to know?
They all nod.
Y/N: very well then. Let me re-introduce my self, I'm Y/N know as the dragon of chaos and supreme king of the dragons. Nice to meet you all.
They all stared at me wide eyed.
Rias: no impossible.
Sona: the last news about the king of dragon is that he's slumbering somewhere in Ural mountain.
Y/N: and I have awaken, thanks to the humans and their nuclear test.
Tsubaki: and what prove do you have to back your claim?
Y/N: ask ddraig over here.
I pointed at issei's gauntlet.
Ddraig:[what he just said is true I was still a dragon when he take up that title from bahamut]
Rias: w-w-what?????
Sona: the bahamut? The dragon of annihilation?
Asia: are you really that Powerful?
Issei: y-y-you can't be him.
Y/N: (sigh) ddraig your over exaggerate, I didn't take the title from him. He just give the title to me. I'm maybe powerful but not as powerful as bahamut.
Ddraig: but you beat all dragon that challenge you in a duel.
Y/N: that is true.
???: Uhh what Happened?
We then see the voice source, it's my sister she's getting up. I can't control my self I just hug her tightly.
Alice: umm brother? Are you okay? What Happened?
Xenovia: you don't remember?
She shake her head
Y/N: you're kiddnapped that's what happen.
I then let her go
Alice: what do you… ahhh!!
She suddenly holding her head. Wincing in pain.
Alice: i-i-i remember now! Kokabiel he has…
Y/N: it's okay everything is okay now, Kokabiel has taken care of.
Alice: by who and how do you know about all of this?
Y/N: well…
I just scratch my head.
Alice: oh no you can't be serious.
Koneko: actually he's the reason why is Kokabiel turned into a pile of feathers.
My sister just see me wide eyed and look of disbelief.
