PersonaQeminod1: I have planned for Itachi to tell the orc about his background, however when I will do it is something I haven't even figured out yet.

youngdrgn: your welcome

duked: I already PM'd you about it so…. No point in me saying it twice.

Chapter 12: Battle of kuoh academy!

Sona and her peerage had set up a barrier around the academy to keep anything drastic to affect the outside or damage it.

"Thanks, that helps a lot, Sona." Rias thanked her childhood friend and rival.

"But that's only if conditions remain the same." Sona said, reminding Rias that the barrier could still be broken if anything to dangerous happens.

"That's true." Rias commented.

Tsubaki then appeared from a magic circle.

"Vice president, where's Irina?" Issei asked concerned.

"Her condition is not life threatening, thanks to Aregento-san's treatment." She responded.

"I'm so glad!" Asia said in relief.

"Still the location of Xenovia remains unknown." Itachi commented.

"Where in the world did she go?" Issei questioned.

"Nothing yet from Kiba either." Saji commented.

"We haven't been able to contact him." Itachi replied.

"But I believe that he's safe." Issei assured.

"I'll keep the barrier up, but I might not be able to keep the school from collapsing. As unbearable as that is…" Sona said.

"I won't let that happen." Rias assured.

"Rias, it's not too late to contact your brother even now…" Sona said.

"I don't see you contacting your big sister." Rias replied.

"My family is… Your older brother loves you, doesn't he? Sirzechs would definitely come to help you. That's why…"

"I've already contacted Sirzechs-sama." Akeno said. "And he said his also going to contact Michael-sensei to come and help."

"Akeno, why did you contact him on your own?" Rias asked.

"Rias, I understand that you don't want to be a bother to Sirzechs-sama. But the enemy is a leader-class fallen angel. He is not someone you can take on your own. Let's have the maou help us with this one." Akeno said.

Rias sighed in defeat.

"Thanks for your understanding, buchou. Sirzechs-sama's forces will arrive in about one hour."

"Oh goodness, I just can't win against you. One hour, huh."

"Let me deal with Kokabiel, Rias." Itachi said.

"No way you are not doing this on your own!" Rias replied.

"Rias let's face it, of all of us I'm the only one strong enough to stall him for one hour, even defeat him." Itachi argued.

"You were the one that told me. That if you do things on your own your bound to fail. You said that." Rias said.

"It's too dangerous, please leave it too me." Itachi said.

"I can take care of myself you don't have to worry about me so much. We all can take care of ourselves, there is no need for you to carry all of the burden on your own." Rias assured.

"Hm, guess I can't win against you on this one. But promise me that if it seems to dangerous you will stay back and let me handle it."

"I promise nothing." Rias said with a smile.

"You really are stubborn, you know that?"

"Yeah."

"Let's go then."

The orc walked into the school planning a strategy on the way. "Issei, you will be on support." Rias said

"Support?" Issei asked.

"I want you to use your ability to transfer your power to the others to raise their power." Rias explained.

"I see. Roger!"

"Itachi you will fight Kokabiel head on while the rest of us help from the background, to stall time until Issei can use his transfer ability on everyone."

"I understand." Akeno said.

"Yes, buchou." Koneko said.

"Understood." Itachi replied.

"We need to be on the offensive for this battle. We have to get into the school and prevent Kokabiel from releasing his power. Unlike the fight with Raiser, our lives will be at risk this time. But I will not allow us to die. My dear servants, survive so we can go to school together again!" Rias said.

""Yes, ma'am!"" They replied.

Promotion queen

Issei used promotion. "Itachi-senpai, aren't you going to use promotion?" Issei asked.

"I don't think I will need it just yet." Itachi commented.

They stepped outside on the school track field seeing a golden magic circle in the air.

"What in the world is that…?" Asia asked.

"It seems like the four Excaliburs have been made into one. Seems like something he would think of." Kokabiel's voice came from above, everyone looked up to see him sitting on a floating throne.

"Kokabiel!" Rias said.

"Is Sirzechs coming, or is it Serfall? Or maybe that Shadow demon?" Kokabiel asked.

"We're here in their place." Rias said.

Kokabiel made a light spear in his hand, making everyone go around Rias in a defensive form. Kokabiel threw the light spear on the gym hall making it explode into rubble. "Ah well, a little diversion can't hurt." Kokabiel said in a bored tone.

"Are you scared partner?" D-draig asked.

"I've never seen such a big spear made of light. It's like it's from a different dimension." Issei replied.

"Of course it's from a different dimension. We're talking about a man who survived fighting with God and Satan."

"Can we really beat a guy like that?" Issei asked.

"When it comes down to it, I'll beat him even if I have to turn most of your body into a dragon. But with Itachi over there it doesn't seem to be needed."

Issei turned towards Itachi, who was releasing so much energy that stones began to levitate from the ground as well as an orange glow appeared around him.

"Since you came all this way, I suppose I'll have you play with my pet." Kokabiel said releasing a wave of light on the ground making a magic circle, that had flames erupt from it revealing a huge three headed dog.

"Cerberus?" Rias said.

"Hades's watchdog huh?" Itachi said.

"The watchdog… of Hades…?" Asia questioned in a frightened tone.

"To bring that to the human world… let's go Akeno, Koneko!" Rias said.

""Yes Buchou!"" They replied.

"Issei use you sacred gear to enhance our power!" Rias said.

"Yes buchou!"

Boosted Gear!

Boost!

Issei activated his boosted gear while Akeno transformed into her shrine maid outfit.

"Asia get back!" Issei said.

"Yes." Asia replied.

Itachi made a hand sign.

Shadow clone jutsu!

Itachi made a hundred clones that jumped Cerberus. Making a blue orb in their hands.

Rasengan Mega Barrage!

The rassengans collided with Cerberus making it howl in pain as it was being pushed down to the ground.

Cerberus spewed out flames which Itachi simply absorbed.

Rias and Akeno attacked it with destruction and lightning magic, while Koneko delivered a kick to one of the heads.

Two more Cerberus's appeared with one of them attacking Asia. Issei jumped in and took her out of harm's way.

Boost!

"If I attack or get attacked the multiplier gets reset… I'll act as bait to draw it's attention. Run away Asia!" Issei said.

"Issei-san!" Asia said as Issei ran towards the dog and leading it away from her. As the beast was about to slice Issei with it's claws Koneko jumped in and punched it in the face.

"Koneko-chan!"

"Please leave this to me." Koneko said.

"But you can't take him on your own!" Issei said.

"I can at least stall for time." Koneko replied.

"Koneko-chan!"

Boost!

"Koneko get back, same goes for the rest of you!" Itachi said making them back away from the beasts.

Blood ran down Itachi's eye as it turned into his enternal mangekyou sharingan.

Amaterasu!

The three Cerberus got lit on fire with black flames. They howled in pain as they were slowly being burned away.

"T-That flame?" Rias said.

One of the dog's head that was not yet covered in flames charged at Itachi, but suddenly it got sliced off as Xenovia jumped in with her Excalibur.

"I've come to provide back up." Xenovia said with a small grin.

"Took you long enough." Itachi replied.

"What is that black flame?" Xenovia asked.

"It's one of my ability's. It's called amaterasu, it's a black flame that will not stop burning until it's caster deactivates it or the target has been burned to ashes, even if you freeze it our put water on it will not stop burning." Itachi explained.

"Did Tannin teach you that?" Rias asked also curious.

"No it's an ability that can only be passed down through my bloodline." Itachi said.

"Does that mean your future children will be able to use it as well?" Xenovia asked.

"Yes, if they want their abilities to go that far."

"What do you mean?" Rias asked.

Itachi looked at Rias with his eyes that were still turned into his eternal mangekyou.

"Your eyes?" Rias said making Xenovia and the others look at them.

"As you know Rias, my bloodline possesses the sharingan eye, however it has a second stage. Mangekyou Sharingan, it increases my abilities to a huge amount giving me the ability to cast an illusion so powerful that it can feel like your trapped in there and tortured for years but it will in real life only last a few seconds. The flames of the Amaterasu is the second ability of that eye the ultimate attack, and the third one is the ultimate defense the Susano'o." Itachi explained making them look at him amazed.

"Oh, what an interesting power you have there." Kokabiel commented.

Itachi gave him a cold stare.

"That girl mentioned Tannin, The Blaze Meteor Dragon King, I heard that he had adopted a human child who turned into a devil, tell me was that you?"

"Yeah, so what?"

Kokabiel chuckled. "I also heard that child was a prodigy like none other have seen before since Michael Shadow. If that's the case how about you entertain me for a bit."

Itachi powered himself up releasing a huge amount of flames around him.

Issei's boosted gear let out a green glow.

"That's the sign that it's reached an appropriate multiplier for fighting." D-draig informed his partner.

"There was something that convenient built in?" Issei said.

"You and the sacred treasure both mature every day. It just made what you desired into reality."

"Itachi-senpai!"

"Issei-san?" Itachi questioned.

"Boosted Gear gift!"

Transfer!

A green glow surrounded Itachi's body as his flames got twice as much powerful. "Thanks, Issei-san."

"Hm, let's begin shall we." Kokabiel said as suddenly several swords popped out of the ground to which Kokabiel flew up. Kiba jumped into the scene.

"Glad you could make it." Itachi said.

"Are you kidding, I wouldn't miss this." Kiba replied.

"That was unexpected." Kokabiel commented.

"Take this!" Rias yelled throwing a huge wave of destruction magic at Kokabiel.

"Hn." Kokabiel muttered as he just used his hand to bounce it off towards the ground making an explosion that made a huge crater in the ground. "At the moment I'm only interested in the son of Tannin."

"It's complete!" Valper said as the light around the magic circle increased. Revealing a sword.

"Crap!" Kiba commented.

Valper let out a laugh. "With this, it's finally…"

"I get the massive power that results from combination of the swords. That's the trade off." Kokabiel said.

"You used that power to make the ground collapse?" Rias questioned.

Issei went closer to the source staring at the sword. "Is our town seriously going to disappear?" Issei asked in fear.

"You should run away from here. This town will be destroyed in less than 20 minutes." Valper said.

Kiba readied his sword so did Xenovia.

"If you want to protect it, you have to defeat me. What will you do… Rias Gremory?" Kokabiel said bringing out his wings.

"That's obvious!" Rias said releasing a wave of destruction magic. Which Kokabiel grabbed with his right hand, Akeno released a wave of lightning which Kokabiel grabbed with his left hand slamming them together making a huge ball throwing it towards Rias. "You fool!"

Itachi jumped in between and made a few hand signs.

Fire style: Majestic destroyer flame!

Itachi spewed out a huge amount of flames that expanded covering more area. It clashed with the ball and exploded. "Are you alright Rias?" Itachi asked.

"Yes, thanks Itachi." Rias replied. "Huh. Yuuto?"

Itachi looked down to see Kiba walking towards Valper.

"Valper Galilei, I'm a survivor of the Holy Sword Project… or more accurately… of those you killed." Kiba said with hate directed at Valper.

"Hm?"

"I've been able to live on by being reborn as a devil. I could not die. I needed to avenge the deaths of my comrades!" Kiba said charging towards Valper.

"No, Yuuto!" Rias yelled. As Kokabiel threw down a light spear at him making a large explosion were Kiba was. When the smoke cleared Valper was standing there protected by a small barrier.

"Kiba!" Issei screamed. Kiba was on the ground.

"You were able to avoid a direct attack? You're a quick little rat." Kokabiel mockingly stated. "Freed."

"Yes boss?" Freed appeared on the scene.

"You finally came out!" Issei said.

"This is the last piece of entertainment. Use the Excalibur with the power of four swords to get rid of all these guys." Kokabiel ordered.

"You got it!" Freed replied. "The cute Excalibur with the super wonderful specs? I did in fact receive one. Now who shall I get rid of first…?" Freed lifted up the Excalibur. "Well, I'm just gonna chop up that devil and scum bitch believer a little, kay?"

Xenovia charged at Freed, delivering a slice with her Excalibur, but Freed vanished with his improved speed.

"Too bad." Freed commented. "Have you met? This is the Chopper Rapidly!" He appeared behind Xenovia. "This freshly made, piping hot, super amazing little Excalibur can make anything happen!" Freed delivered a slice attack, to which Xenovia turned around and made a back flip then delivering a kick to Freed's cheek.

"You scum bitch! You have some nerve to kick me in the face like that! I'll definitely tear you apart!" Freed said expanding the Excalibur and making it float like a ribbon in the wind, Xenovia jumped back dodging the attack just in time. "It's not just mimicry!" Freed said lifting the sword upwards making the top split in six spears flying towards Xenovia. To which Xenovia blocked with her Exalibur.

"Nightmare." Freed said making several reflections of himself. "This is the power of the Excalibur Nightmare! Ba-dum! dum! dum! dum!"

"An illusion?" Xenovia questioned.

"Now, Transparency!" Freed said making the blade seem invisible.

Xenovia blocked every blow Freed delivered. "So he can use the powers of the other Excalibur's his absorbed."

"Now brace yourselves!" Freed charged at Xenovia, Koneko threw Issei at Freed having Issei delivering a kick to Freeds face.

"Don't forget about us!" Issei yelled.

Kiba struggled to get back up, clenching his fist in the dirt while panting.

"I'd heard that one of the subjects had gotten away… But for him to have become a lowly devil… I'm grateful to you guys. Thanks to you, I was able to complete the project." Valper said.

"Complete?" Kiba asked.

"You subjects did not have enough of the gene to use the Holy Swords. Knowing that, I was able to conclude that all I had to do was take out the gene from the subjects. Then we succeeded in crystalizing them. This contains the genes from that time in their crystalized form, although this is the last one." Valper said holding a dark blue crystal in his hand.

Freed then let out a sinister laughter. "All the guys other than me died halfway in because their bodies couldn't take all the genes. If you think about it that way, I'm super-duper special after all, huh?"

"You bastard!" Issei yelled.

"That's?" Xenovia said getting a flashback of Irina receiving a similar crystal to the one Valper is holding. "When a holy sword user receives the blessing something like that is put into their bodies… So that's to make up for deficiency in genes?"

"Those hypocrites. After excommunicating me as a pagan, they shamelessly use my research. In any case, we're talking about the angel leader Michael here. Even if he took genes out of the subjects, I'm sure he didn't kill them." Valper said letting out a laugh.

Kiba got up. "There was no need… to kill us either… Why?" Kiba asked with an angry look on his face.

"You all were nothing more than the materials used in a top-secret project. Once we were done, there was nothing left to do but dispose of you."

"We believed it was for God and bore it the whole time. That was… we were… project materials… to be disposed of…" Kiba said clenching his fist.

"That's terrible." Asia said while letting out a few tears.

Itachi had bangs covering his eyes, while clenching his fist.

"Heh." Kokabiel chuckled. Itachi then exploded with flames flying up to Kokabiel delivering a punch to his face. Itachi's hands were now covered in purple scales as well as his cheeks. Dragon Force!

"If you want it so badly, here." Valper said throwing the crystal in front of Kiba. "We've already gotten to the point where we can mass-produce higher quality ones."

Kiba picked up the crystal bringing it up to his face. "Everyone."

"I'll never forgive you, you old bastard!" Issei yelled.

"Valper Galilei." Kiba said with venom in his voice. "How many lives did you toy with for the sake of your own research and desires?" The crystal Kiba was holding started to glow.

"What's that?" Asia asked.

"People?" Koneko questioned.

"Yeah that's what it looks like." Issei said.

Itachi was still fighting Kokabiel in midair. Kokabiel made a huge light spear and threw it at Itachi.

Blaze meteor dragon: Roar!

Itachi spewed out a huge amount of flames that collided with Kokabiel's light spear making an explosion. Itachi glanced towards Kiba. "Kiba." Itachi muttered. Suddenly he jumped to the side avoiding another light spear.

"You are amusing indeed son of Tannin!" Kokabiel said with a large grin on his face.

Meanwhile back with Kiba. "I kept thinking… about whether or not it was okay for me to be the only one still alive. There were kids who had more dreams than I did… Kids who wanted to live more than I did… I wondered if it was okay… for me to be the only one living a peaceful life." Kiba then looked around to see the spirit of everyone form the project, then the spirit of a little girl tugged on his shirt giving him a smile. They all flew around Kiba. "It's okay…" One of the girls said. "If everyone gathers together…" another girl spirit said. "Take us in…" One of the boys said. "It's not scary, even if there is no God… even if God isn't watching over us…" The little girl said. "Our hearts will always be…" One of the boys said.

Kiba let out a few tears and gave a smile. "One." A blue light merged with Kiba.

"It's heartwarming." Koneko commented.

"What's this… I can't stop crying." Issei said whipping a few tears away.

"That knight has peaked. When the user's thoughts and whishes go against the natural course of things in the world, the sacred treasure peaks. That is the Balance Breaker." explained.

"Oh?" Kokabiel mused.

"My comrades didn't want me to wish for revenge. That's not what they wanted. But I felt like I had to defeat the evil that was before me so that there would not be others like us…" Kiba said summoning a sword. "…Created anymore."

"Freed!" Valper called out to his henchmen.

"Coming!" Freed jumped in between them.

"Hmph, you fool! You should just let yourself be disposed of." Valper mocked.

"Kiba!" Issei yelled. "Beat that bastard Freed and those Excaliburs! Don't waste their feelings and their souls!"

"Issei-kun."

"Do it, Yuuto." Rias said. "You are part of my family, part of the House of Gremory. No knight of mine would lose to something like an Excalibur."

"Yuuto-kun I believe in you!" Akeno said.

"Fight!" Koneko said.

"Kiba-san!" Asia said.

"Everyone…" Kiba muttered, when Kokabiel was knocked down to the ground, with Itachi appearing in front of Kokabiel delivering a kick to his gut sending him flying into a soccer goal.

"You can do it Kiba." Itachi said.

"Itachi-senpai."

"Itachi look out!" Rias said sending a wave of destruction towards a light spear Kokabiel threw towards Itachi, the collision made an explosion. Rias then went to Itachi's side along with the rest minus Kiba and Asia.

"You guys should focus on helping Kiba, I've got this." Itachi assured.

"But?" Rias said.

"I'm fine, thanks for warning me by the way. Trust me I will be able to keep this warmonger occupied." Itachi said with a smile.

"Heh, you really are an interesting kid. I will take my time destroying you." Kokabiel said flying back up in the air with Itachi after him.

"Look who's chasing who here you damn warmonger." Itachi mocked.

Kiba and the others looked in amaze as Itachi was able to go toe to toe with a leader-class fallen angel.

"What's with this moving scene you're creating?" Freed asked in a mocking tone. "Just listening makes my skin crawl… I can't take it anymore! I need to hurry up and cut you all into pieces so I can feel better."

"I will become a sword." Kiba said. "Comrades whose souls have merged with mine, let's overcome this together! Our thoughts and wishes can now be accomplished." Kiba sword let out a light and dark energy. "I'll become a sword for buchou and for my comrades. Sword Birth!" Kiba's sword was now a merge of holy and dark energy. "Sword of Betrayer, a sword vested with both holy and devil powers. Stop it if you can!"

"A holy devil sword that's impossible!" Valper said. "For two opposing elements to mix together like that… Something like that shouldn't be possible!"

"Rias Gremory's knight… are we still on the same side?" Xenovia asked.

"That's what I'd like to think." Kiba replied.

"Then let us destroy that Excalibur together."

"Is that really okay?"

"At this point, even though it's a holy sword, it isn't holy any longer. It is a strange sword."

"I understand." Kiba said, as Xenovia stabbed her Excalibur in the ground. Extending her palm to her side while muttering a few words.

"Peter, Basilius, Dionysius, and the Blessed Virgin Mary…! Please hear my prayers!" Xenovia made a magic circle were out came a large blue sword tied in chains. "In the name of the saint living in this blade… I set you free!" She grabbed the holster making the chains break. "Holy Sword Durandal!"

"A holy sword?" Kiba questioned.

"A sword on par with Excalibur, said to cut everything in this world." Xenovia said.

"That's impossible. My research didn't go into how to use Durandal." Valper said.

"Unlike Kiba or Irina, I'm one of the few naturals." Xenovia said.

"One who is perfectly suitable, also known as a true holy sword user?" Valper said.

"This wild guy cuts to pieces anything he touches. He doesn't always listen to me, either. Besides that, he's infinitely dangerous if he's not shut up in another space." Xenovia said.

"Is there even such a thing?" Freed questioned powering up his Excalibur. He extended the Excalibur and tried to attack Xenovia who just used Durandal to destroy the tips of the balde. "And here we have a super dramatic plot twist!" Freed said.

Xenovia jumped up in the air preparing to strike. "Yours is just a broken holy sword it's no match for my Durandal!"

"You scumbag!" Freed said vanishing at full speed as Xenovia delivered a blow. But Kiba suddenly appeared behind him preparing a strike." That sword!" Kiba said as he delivered a blow which Freed blocked.

They were both moving in immense speed. "…isn't enough to severe our hopes!" Kiba said. Delivering a strike at the Excalibur making it break in half,

"It broke! Seriously…? I was beaten by some lowly devil scum? No way…" When blood suddenly gushed out from his shoulder.

"Did you see that? Our powers overcame Excalibur!" Kiba said.

Freed got up holding a gun. "It's not over yet pretty boy!" As Freed was about to shoot, he felt a piercing pain through his neck, seeing a kunai piercing through him. He turned his head to the side to see Itachi standing there giving him a cold glare. Freed held over his throat as he began to choke on his own blood, blood started to ran down his mouth. "Gugh..gugh..gugh….D….am…n…it." Freed fell to the ground dead.

"Man brutal." Issei commented as the other nodded in response.

"F..Freed?" Valper was shocked. "Impossible. In theory, the fusion of holy and devil powers is…"

"Valper Galilei, prepare yourself." Kiba said pointing the sword towards him.

"That's right. I get it now! If the balance between the holy and devil powers is disrupted, it could be possible. Which is to say not only the Devil King, but also God…" Before Valper could finish he was pierced with a spear of light and vanished into nothingness.

"Valper, you really were very talented. Your aptitude must have helped you reach that conclusion." Kokabiel appeared with his clothes having several burn marks as well as his face having some scratches from his battle with Itachi.

"Kokabiel, you haven't had enough yet?" Itachi asked in a mocking tone.

Kokabiel looked at him with an amused smile.

Flashback:

"Look who's chasing who here you damn warmonger." Itachi mocked flying after Kokabiel, Kokabiel made several magic circles releasing several light spears.

Itachi made a few hand signs magic some magic circles around him as well.

Fire style: Fire ball barrage!

An equal amount of fire balls collided with the light spears making several explosions.

When Kokabiel looked at the smoke clearing there was no sign of Itachi.

Blaze meteor dragon: Iron fist!

Itachi flew up on Kokabiel's side delivering a punch to his face.

Kokabiel shock the pain off. "Don't get cocky brat!" Kokabiel made a huge light spear and threw it towards Itachi. Itachi fused his hand with lightning Chidori! delivering a wave of it towards the light spear destroying it.

"I will give you one chance to give up, leave and never come back." Itachi warned.

"Heh, now that's funny, me give up to some lowly devil! Forget it!" Kokabiel went flying towards Itachi about to deliver a punch, but Itachi grabbed his wrist and delivered a punch to Kokabiel's face.

Blood ran down Kokabiel's mouth, he whipped it away with his finger and looked at it. "Blood, he shed my blood." Kokabiel grew a tick mark clenching his fist. "You made me shed BLOOD! You are nothing but a low-class devil! I'am a leader-class fallen angel! How, how are you so strong!?"

"With enough training, devotion and hard work, even a low-class can surpass a leader-class no problem." Itachi replied.

"You will never surpass me! You hear me never!"

"Sorry to break it to you, but it's a bit too late for that."

"Damn it! Damn it!" Kokabiel flew at Itachi in full speed, and delivered a series of punches and kicks, which Itachi dodged or blocked.

"If you don't give up now I will be forced to kill you." Itachi said.

Koakabiel became frustrated. "Go..to…hell..you…damn..devil!" Kokabiel eventually managed to deliver a punch to Itachi's face, making him grin.

Itachi turned his head towards him with a trail of blood running down from his mouth. "Is that all?" Itachi asked unfazed by that attack.

"I will destroy you!" Kokabiel yelled as Itachi suddenly vanished, Kokabiel looked around but didn't see any sign of him, when he suddenly appeared in front of him, giving him an upper-kick to the jaw sending him flying, Itachi flew after him delivering a punch to his gut sending him flying towards the ground. Itachi began to inhale his breath.

Blaze meteor dragon: ROAR!

A wave of flames approached Kokabiel who crashed into the ground.

When the smoke cleared Kokabiel was laying there covered in burn marks. "H-How did he beat me like that? Wait a minute, yes it must have been the power he received from the Boosted Gear wielder. Heh, this time I will destroy him Kokabiel flew towards the group, just in time to see Itachi kill Freed and Valper about to realize that big secret. "Wow, he figured it out." Kokabiel said with a grin making a light spear throwing it at Valper.

Flashback end

"Now son of Tannin, and Rias Gremory. Prepare yourselves as I shall destroy you."

"Looks like you learned nothing." Itachi said.

"The power you got from the wielder of the Boosted Gear has worn out, you are no match for me now!" Kokabiel said with a crazed grin.

"Even if that was the case that I used Issei's transfer abilities to beat you, it wouldn't change the fact that I haven't even come close to using my full power." Itachi said

"You mean to tell me you've been holding back the entire time, don't make me laugh!" Kokabiel said in an arrogant way.

"Issei-san, prepare a transfer for the others. I will keep him occupied." Itachi said.

"Right!" Issei said.

Boost!

"Rias, Akeno, Kiba, Koneko, Xenovia please back me up." Itachi said.

""Roger!""

Rias shoot a wave of destruction at Kokabiel who simply blocked it, then Akeno shoot a wave of lightning at Kokabiel who used his wings as a shield. "Are you trying to get in my way, you who possess the power of Barkiel?" Kokabiel asked.

"Don't lump me in with that man!" Akeno said with anger.

"Barkiel?" Issei questioned.

"His one of the fallen angel leaders, he uses lightning and thunder." Itachi explained.

"Thunder?"

"You've fallen so low as to become a devil now? What an amusing House you have, Rias Gremory." Kokabiel said while letting out a chuckle. "The son of Tannin, The Red Dragon Emperor, A ruined Holy Sword Project subject… And Barkiel's daughter!"

"What!?" Xenovia asked.

"Akeno-san's… the daughter of a fallen angel?!" Issei asked.

"I heard you were saved by Michael Shadow, which is actually kind of ironic. Since Shadow Demons hates fallen angels, in fact the rumor has it that it was an army of elite-class fallen angels that destroyed the Shadow Demon clan!" Kokabiel said making Akeno's eyes widen in shock as well as the rest of the group. "Yes Michael's father, mother and little sister, were killed by fallen angels! I'm surprised that he didn't kill you in fact!"

Akeno shoot a large wave of lightning at Kokabiel while screaming in rage while letting out a few tears.

"That actually hurt a bit, heh." Kokabiel mocked. "Rias Gremory, like your brother, you seem to like inferior products."

"I won't forgive your thoughtless remarks against my brother… our Maou. Your insult towards my servants deserves death!" Rias said.

Kokabiel flew down to the ground. "Then try and destroy me, little sister of the maou, son of Tannin. Your confronting the archenemy of devils, you know. If you don't take advantage of this chance, this is as good as you'll get!"

Itachi flew up to Kokabiel delivering a punch to his face. "You wanted a rematch, right? Well then let's go. Oh and one more thing don't you dare insult Rias, Akeno, or any of us!"

Kokabiel made a sword of light. "I will cut you up boy!"

"Issei focus on powering up!" Itachi said.

"You got it!"

Boost!

"Xenovia, Kiba now!" Itachi said.

Xenovia leaped up in the air ready to strike Kokabiel with Durandal, while Kiba readied his holy devil sword. Kokabiel made two swords out of light blocking the strikes. Then Itachi appeared in front of him with his foot fused with flames.

Blaze meteor dragon: Talon!

Itachi delivered a kick to Kokabiel's face making him fall back. Kokabiel broght his swords of light together in an x-shape slicing them together making an x-formed wave of light that headed towards Itachi who didn't move an inch.

"Itachi!" Rias screamed. When suddenly the light x-wave was destroyed by a large spirited red skeleton hand that was a part of a red ribcage around Itachi.

"The third, and final ability of the mangekyou."

Susano'o!

The ribcage formed into a red spectral skeleton.

"W-What the!?" Issei questioned.

"That's Itachi's power." Rias muttered in awe.

"Huh, that's an interesting power. I wonder how powerful it is?" Kokabiel wondered with an evil grin. Kiba used this opportunity to attack by using Sword Birth to make two blades in each of his hands, as he was about to strike Kokabiel. Kokabiel caught the swords using his hands. "Useless."

"Not yet!" Kiba said forming a third sword in his mouth cutting Kokabiel on the cheek.

"You bastard!" Kokabiel shoot a wave of light towards Kiba, to which Xenovia used her Durandal to block the attack and slicing it in half.

Boost!

"Damn it just a little more." Issei muttered.

"You guys sure are fighting hard for people who have lost their master." Kokabiel said to Xenovia.

"What?" Xenovia asked.

"What do you mean?" Rias asked.

"Kokabiel, what do you mean by that?" Xenovia questioned.

"Oh my, I let it slip."

"Answer me, Kokabiel!" Xenovia demanded.

Kokabiel let out a sinister laugh. "That's right, since I'm trying to start a war, there's no point in hiding it any longer. In the previous three-way war, God died along with Satan and the four great Devil Kings who took over after he died!" Everyone widen their eyes in shock minus Itachi.

"T-That.. can't be true." Xenoiva muttered shaking.

"God… is dead?" Rias questioned in a shocked tone. "That's ridiculous. I haven't heard anything about that!"

"During that war, the devils lost their mighty leader Satan who was said to be the strongest being at one point, then the four Devil Kings was formed in order to fill in not just leader ship, but the power Satan possessed as well, they also lost the four devil kings in the end along with several high-class devils, and the angels and fallen angels lost almost everyone except their leaders. The angels couldn't increase their numbers, and purebred devils are rare." Kokabiel said.

"That… That can't be true!" Asia said.

"All sides have been ruined to the point where they have to rely on humans to survive. Angels, fallen angels, devils. The leaders of the three factions had to seal away this information so that the God-fearing humans would continue on." Kokabiel said.

Xenovia fell to her knees. "Lies… All lies…"

"You don't believe me, then ask you friend the Shadow Demon." Kokabiel said.

"What does Michael-sensei have to do with any of that?" Rias asked.

"What do you mean? He was there, he saw it happen. In fact, he was fighting the angel duo Michael and Gabriel." Kokabiel said.

"Michael-sensei, knew… That God was dead." Asia muttered.

"Well not that I care about that anyway. What I can't really take is the fact that with God, Satan, and the four Devil Kings dead, it was decided that continuing the war was pointless! I can't take it! I can't take it! You want me to calm down after raising my fist? If we had continued fighting, we would have won! Even that bastard Azazel declared that there would not be another war! What the fuck?!" Kokabiel yelled in rage.

"God does not exist anymore? Then what about the love that is given to us…?" Asia asked.

"The angel leader Michael is doing a good job, you know. He's keeping the angels and humans together in God's place." Kokabiel said.

"Archangel Michael is acting as God's agent? Then we've…" Xenovia said.

"As long as the system works, prayers and exorcisms will operate to a certain extent." Kokabiel said making Asia pass out in shock. Koneko grabbed the passed out nun.

"Asia!" Issei said.

"That's a natural reaction. I'm surprised that I can still think at a time like this." Xenovia said.

"However, the number of believers in God has fallen drastically. Without anyone to manage the balance between good and evil, it's no wonder that something contradictory like the holy devil sword would appear." Kokabiel said while glancing over to Kiba's sword. "Otherwise it would be unthinkable for good and evil to mix like that. I'll continue the war even if I have to do it myself by taking your heads!"

Itachi had his Susano'o deliver a punch on Kokabiel. "Your welcome to try." Itachi mocked.

"I've had enough of you I will end you right here!" Kokabiel said making the biggest light spear anyone has ever seen. While Itachi's Susano'o formed a rotating thing in it's hand.

"Take this!" Kokabiel yelled throwing the light spear.

Yasaka Beads!

Itachi's Susano'o threw it at the light spear making a huge explosion in the air.

"God…is…dead." Xenovia kept muttering.

"Does it really matter if God's dead or not." Itachi said making everyone including Xenovia to look at him. "Even though his dead his love and will still exist, he is still in the heart of believers, and as long as people believe in him, he will always live in their hearts."

"Huh, nice words coming from a devil. This time I will destroy yo-!..." Just as Kokabiel was about to finish, his body from the waist down was cut in half.

"I've heard enough of your babbling." A familiar voice was heard.

Michael landed in front of the orc with his hand letting out a dark purple energy formed as a blade. ""Michael-sensei!"" the group minus Itachi said.

"Once I heard from Sirzechs that you were attacking the school and my students, I rushed here as fast as I could."

Kokabiel coughed up blood. "Y-You…Damn…Shadow..D-Demon!"

"Enjoy otherworld, freak." Michael said releasing a dark purple energy wave from his palm destroying Kokabiel's body.

"Guess that's over." Issei muttered.

"Michael Shadow, there is something I must ask you." Xenovia said.

"What?"

"Did God die during the last war?"

"Did the warmonger tell you?" Michael asked.

"Yes." Xenovia replied.

Michael sighed. "Yes he did die."

Xenovia looked down with a sad expression. "So it is true then."

"And here I hoped to take down Kokabiel." A voice was heard.

"Who's there?" Michael asked. When the barrier around the school was destroyed. Revealing a blue light falling down from the sky. The light exploded in front of the moon, showing someone in a white dragon armor with blue wings.

"My body is shaking… who is he?" Issei said.

"I see that's The Vanishing Dragon." Itachi said.

"Indeed." Michael commented.

"Vanishing Dragon? Then that guy's…" Issei said

"My name is Albion. I possess the sacred gear of Divine Dividing, it halves the power of whatever it touches every 10 seconds using the power I absorbed for myself."

"Halve the power?" Issei questioned.

"The Red Dragon Emperor multiplies its owner's power and transfers it to something, while the White Dragon Emperor halves the enemy's power, using it to sustain the owner." Itachi explained.

"Guess since the Shadow Demon took out Kokabiel, and the son of Tannin took out that priest, I'll just take the priest's corpse and leave." The White Dragon said picking up Freed's corpse.

"Are you ignoring me, White one?" D-draig asked.

"You are still alive, Red one?" Albino asked

"These are the conditions we get after we finally meet, huh?" D-draig said.

"It's fine. We are fated to fight someday. These things happen. Let's meet again D-draig." Albino said.

"Yeah, let's, Albion."

"Hey! What's the meaning of this? What are you?" Issei asked.

"Become stronger then we can talk." The mysterious person said vanishing in a blue light.

"Rias." Sona said entering the scene.

"Sona?"

"I can't believe the White Dragon burst in like that." Sona said.

"But the town is safe and that's all that matters." Rias said.

"That's true." Sona replied. "Well then, Tsubaki, we need to repair the damage to the school."

"We should be able to manage before school starts." Tsubaki replied.

"Then we will also help." Rias said.

"No, taking care of the school is the job of the student council." Sona said.

Kiba looked at his sword. "Is it over? No, there are still people who took over that man's research. My fight is not over yet."

"It seems Kiba's fight has only begun." Itachi said.

"Well he did at least realize his mistake." Michael said.

Itachi looked over too Akeno who looked at Michael with a sad look. "Michael-sensei?"

"What?" Michael asked.

"Was it fallen angels that killed your clan?" Itachi asked.

Michael's face turned dark. "No."

"Then who?" Itachi asked.

"A monster." Michael replied. "Why did you ask me that anyway."

"Kokabiel said that it was a rumor that it was fallen angels who did it, I'm guessing it made Akeno feel a little guilt for being half-fallen angel." Itachi said.

"True there is such a rumor, however it was started by the real culprit." Michael said.

"Maybe you should tell Akeno that." Itachi said.

Michael looked at Akeno who was looking down on the ground, he walked up to her. "Itachi told me what Kokabiel told you about my family."

"He did." Akeno replied.

"That was a lie." Michael said, making Akeno look up at him.

"It was a monster, not the fallen angels. That was just a rumor started by that monster." Michael assured.

"He also said that Shadow Demons hate fallen angels."

"Although for some Shadow Demons that may have been true, it's not that way for me." Michael placed his hand on the top of her head. "Besides I could never hate you." Akeno embraced Michael crying a little on his jacket, Michael accepted the hug and hugged her back.

"Now then Yuuto." Rias said.

"Yes." Kiba looked up to Rias seeing her having a magic circle at the palm of her hand.

"This is your punishment for moving on your own. One thousand spankings." Rias said with a smile.

"What?!" Kiba said, while Issei let out laughter.

Next morning the orc

"Hey son of Tannin." Xenovia said wearing a kuoh academy uniform.

"Hello Xenovia-san." Itachi replied.

"Wait why is she here?!" Issei asked.

"I see you made it." Rias said.

"Buchou, what's this…?" Issei asked.

"She's the new knight of Rias's Household." Itachi said.

"Please get along with her." Akeno said.

"Kn-Knight…? Could it be that you…?" Issei questioned. As Xenovia brought out her wings and quickly brought them back in.

"You've been transformed into a devil?" Asia asked.

"We were also surprised after being told about it." Kiba said.

"After learning that God had died, I was desperate and begged her." Xenovia said.

"You begged her? Buchou!" Issei said.

Rias let out a light chuckle. "It'll be nice to have the Durandal user added to our ranks. With this, you and Yuuto will be the swordfighters covering our right and left flanks."

"Sometimes she really let's her devil side show." Itachi muttered.

"I transferred to this school as a second-year student today." Xenovia said.

"Is it really all right with you?" Issei asked.

"Without God, my life is meaningless. But is it all right to stoop to this level of the devils, my former enemies? Even if she is the little sister of the Devil King, was my decision correct? Please tell me, O Lord!" Xenovia said suddenly getting a stabbing pain in her head.

"I feel like I've seen this scene before." Koneko said.

'Maybe I should ask the angel leader to allow Xenovia and Asia to pray again.' Itachi thought. 'After all this is getting sad to watch.'

"Speaking of which, what happened to Irina?" Issei asked.

"She returned to headquarters. Irina's faith is deeper than mine. If I were to tell her the truth, I don't know what would happen to her emotional state. Basically, I'm a dangerous person who found out the truth about something I shouldn't have, and I've become a heretic." Xenovia said.

"So then, you became a devil…?" Asia asked.

"I must apologize to you, Asia Argento." Xenovia said.

"Why?"

"Because if there is no God, then there is no hope of salvation or love. I'm sorry. You can hit me if it will make you feel better." Xenovia said bowing her head down.

"That's." Asia said.

"For a holy sword user who should be respected to become a heretic who committed a taboo… It's changed the way I look at things, I cannot forget the attitudes they had. I must have made you feel the same way…" Xenovia said.

"Xenovia-san, I am satisfied with this life. Even though I'm a devil right now, I was able to meet many people who are now dear to me. I really am very happy." Asia said.

"I see. I also have a favor I want to ask you."

"Me?"

"Will you show me around school sometime?" Xenovia asked.

"Yes!" Asia replied.

Xenovia turned towards Kiba. "I'd also like to try my Holy Sword Durandal against the holy devil sword again."

"That's just what I wanted." Kiba replied.

"Now that we've even got a new member… The Occult Research Club is back open for business!" Rias said.

""Yes Buchou!""

And I will stop here!

So that's the end of the Holy Sword arc, I would like to thank you all for your support! And too those who doesn't know me and Damien Falls are writing a fanfic together a Naruto crossover dbz with Itachi as the main character, it has been posted on my profile. It's called. "From Ninja to Saiyan"

Also, I have a little bit of a dilemma in the end of this story Itachi will be the strongest no doubt about it. But my OC will also get stronger of course, and I can't decide what kind of power up I should give him. Here are the options

Option a) A mystic eye power similar to rinnegan. And it boosts up his power 100x.

Or option b) a power up similar to that of a super saiyan, just white hair and not blond, no spiky hair, and it boost's up his power 100x.
