*bang, Crack, Clash, boom* 

"Divine! Boost!"

These sounds echoed through the battlefield as Rias, her peerage, Y/n and his girls attacked the Fallen angel. Rias had fired a massive attack thanks to Issie transferring power into her along with Yubelluna. Isabella and Koneko were next as they rushed at the fallen as he blocked their attacks with his ten wings. Going to attack them with the very things he used to protect himself with Carlamain, Xenovia and Kiba, who had just joined the fight, slashed at him making him redirect his attack. Jumping back Kokabiel narrowly dodged a axe kick from Y/n as his heel cracked the ground underneath him. Kokabiel went to attack him with a light sword but  Yubelluna summoned a massive purple ball of energy blowing him back and exploding in front of her emperor.

"Divine! Divine! Divine!" Ra yelled out as him and his partner absorbed the attack.

Kokabiel ran at Y/n but was stopped by Carlamain as she clashed her sword with his. Isabella was next as she side kicked Kokabiel in the cheek making him stagger a bit. Using his wings the angel went to do an A.O.E attack but missed as Y/n had appeared behind him with his girls on his shoulders before he set them down. Yubelluna and Akeno summoned Lightning and Explosives respectively as Kokabiel protected himself.

Issie watched seeing the gang attack the angel with coordinated attacks. While Asia was healing Koneko when she tried to get a close attack in before Yubelluna's attack went off. She had been pushed back by it before everyone noticed Y/n take off with a sonic boom. Kokabiel looked in shock as a fist was firmly planted into the angels stomach as the both of them flew towards the rubble of the school before the boy shifted and kicked Kokabiel back into the combined attacks of Akeno, Rias and Yubelluna. Everyone was getting exhausted from this Long termed fight.

Even Y/n was feeling a bit tired from absorbing so many attacks. Ra chuckled which made his partner look down at him.

"What's so funny Ra?" He questioned making the dragon speak.

"It's been quite a while since I've seen you get tired. You should end this fight soon. Otherwise the stockpiling effects will damage you once again." He said making Y/n think about it. It had been a few years....ten years to be exact...since he had been taking too many stockpiles.

"Man. I was just about to see how many more I can take." He sighed as Kokabiel blew the smoke off of himself as he seemed to be angry.

"Why won't you all just die?!" He yelled before feeling Y/n grab him and suplex him before rolling onto him and repeatedly wail on his face. But Kokabiel stabbed him in his abdomen with his wings as they intrude through his armor and body making him cough blood. Making the angel laugh seeing how much damage he did.

"Do you like that boy?!" He laughed but had his mouth covered by the boys hand.

"Eh. It was alright. What about this? BLAZE CANNON!" He yelled as his hand glowed and radiated heat making Kokabiel yell in pain before the both of them were consumed by a massive fireball before it went off.

"Divine!" Ra yelled nine times as Kokabiel and Y/n were split apart with Y/n on his feet. "Partner will you stop treating this like a training session!" Ra yelled making Kokabiel look at the sun dragon emperor with rage.

"You've been using me like a training dummy!?" He glared making Y/n rub the back of his head with his armor fading away into golden dust.

"Yeah. I wanted to see how many stockpiles I can get. I haven't been able to see on normal devil's. So a high ranked angel seemed like the right kind of test. To be honest. You have done quite a few hits properly onto me. But now. I'm gonna be taking this seriously."

"You bastard!" Kokabiel yelled as he fired a massive ball of light at the boy making him extend his hand out with his palm facing the angel. A small ball of fire appeared in the middle of his hand.

"Issie I'm borrowing your move." He said as he clenched his fist before reeling his arm back and punched the small ball. "DRAGON SHOT!" He yelled as a massive geyser of fire destroyed the sphere. Making Kokabiel growl as he fired multiple spheres at the attack but they were consumed. Flying away he hissed in pain as half of his wings burned off making his eyes blood shot.

"SUN Dragon emperor!" He yelled before taking off at him but he was met with a deathly glare from Y/n as he slammed his right armored fist into his cheek sending the angel into the ground as smoke and a crater the size of a meteor appeared as Y/n pants. His glow vanished after the attack as Ra spoke out. "Release."

Y/n sighed before feeling his nose seeing blood making his sigh. "Only fifteen, man. I really have been getting a bit weaker." He sighed as Issei walked up to him.

"Weaker? You took down Riser and now this guy." The Welsh dragon emperor pointed out.

"Yeah but I could've gotten more. I think I'm getting too tired. Our training regime isn't just for you. It's for me too. I've been out of shape for a few years now."

"Oh I can tell." A sinister voice spoke. Y/n pushed Issie out of the way before being impaled by a light sword as he looked down to see Kokabiel fuming with rage. His attention then noticed the golden light sword in his chest. 

Yubelluna and Isabella were the first to react as they attacked the angel but accidentally attacked Y/n since he used his body as a shield. Yubelluna glared at Kokabiel as he smirked behind Y/n's body. Hearing the sun dragon emperor grunt in pain Issei noticed him grabbing the sword as he hissed in pain as Kokabiel chuckled. 

"Feels painful huh? You can't stockpile anymore. Ra's little champion is nothing but a fluke." He laughed as Y/n began to chuckle a bit as his blood stained the sword. Looking up at the fallen angel Y/n had blood leaking from his mouth and nose as he raised his right hand before slamming it onto the sword.

"DIVINE!" Ra yelled as Y/n absorbed the power making it shrink a little. Just enough to make the pain bearable. But he staggered as Ra yelled out "Dreadful." making him puke blood onto the floor. Issie looked at his friend with shock as he seemed to have gone limp on the sword of light. "Huh, haven't heard that in a bit." 

Kokabiel smirked before having the sword vanish as he tossed Y/n's body away from him into the air. Summoning a light sphere the attack flew at him. Yubelluna flew as fast as she could and caught him as the attack missed the two mere centimeters from them. Landing on the ground Yubelluna looked at him with shock as he wheezed. 

"I guess I got a little carried away there." He chuckled as Yubelluna gently set him down before grabbing her staff and glaring at Kokabiel. 

Just then the priest that was the head of the Excalibur was getting excited as his project with the symbol he needed to make Excalibur whole again. Kiba took noticed of this man as he was the one to kill all of his original friends that gave their life for him to leave the excaliber program that used children to test the holy sword. The man noticed Kiba as he was tired from the fight. "Well, Well. To see one of the subjects to leave the program as a lowly devil is a sight to be hold." He chuckled. "I must say; I'm grateful to you guys. Thanks to you, I was able to complete the program."

"Complete?' Kiba let out from his exhausted breathing.

"You subjects didn't have enough of the gene to complete the holy swords . So I concluded that the only way was to take the gene out of the subjects." He smiled maliciously. 

This shocked everyone except for Kokabiel. Who had a smile on his face. 

"We were able to crystalize them. This contains the genes from when they were crystalized." He smirked showing a blue object in his hand. "This is the last one." He smiled as Kiba looked at it while Y/n was struggling to get up. 

"That's what the honored ones put into their bodies. This was to make up the deficiency in genes?" Xenovia spoke in shock as Y/n glared at the priest. 

"There was no need to kill us.....Why?" Kiba asked getting to his feet. 

" You all were just materials, once we didn't need you, we simply disposed of you." He smirked before tossing the object to Kiba.

"That's terrible." Asia said as she was tearing up while healing Rias. 

"We thought we did this all in the name of god."Kiba spoke before reaching for the object. "For us to be disposed of...." 

"Kiba!" Y/n yelled out as he was getting to his feet with the help of Yubelluna. "What you thought was right in the name of god wasn't a joke. They are the ones to sully the name of God." He said pointing at the priest. "His love isn't conditional, those that use his name in injustice don't receive the grace of him. Believe me." 

"Oh?" The priest smirked looking at the boy. "I've heard of you child. The boy that was chosen by the lesser god RA. To have graced me with your presence is that of a sin of itself." He smirked making Y/n glare at him for him to sully the name of the being, no the man of his life and guidance is repulsive. But Y/n smirked at him.

"I'm letting you know right now. Valper Galilei when you die here and now by Kibas hand. No god, let it be the reaper of death or Anubis, will meet you in libero. When you die a demon made of hellfire shall take you to where you will be damned for the rest of your pathetic life." 

"How many lives did you toy just for you research and desires?" Kiba questioned as the crystal glowed as people began to appear around him as spirits. 

"Are those people?" Asia questioned as Akeno looked on.

"It's probably the differences in power and Kiba's trembling heart that is causing them to be freed from the crystal."

"I kept thinking......about whether or not if it was okay for me to live. There were kids there that had more dreams than I did. Who wanted to live more than I did. I wondered if it was okay for me...to be the only one to live a peaceful life." He said before opening his eyes due to one of the spirts tugging at his sleeve making him look down to see the youngest one smiling at him. 

"It's okay....if everyone gathers together...take us in...it's not scary, even if there is no god... even if god isn't watching over us...Our hearts will always be..." The spirts said as Kiba smiled with tears. "One." 

Everyone including Y/n's girls were crying due to the heartwarming scene except for the sun dragon emperor since the sacred beasts could feed of of his emotion. 

"The knight has peaked."  Ddraig started as Ra spoke as well.

"When the users thoughts and wishes go against the natural course of things in the world, the sacred treasure peaks." Ra spoke making Y/n nod.

"This is the balance breaker." Ddraig spoke making the two emperors nod. 

"Kiba. you have my blessing to end this Fucker." Y/n smirked making his friend nod. 

"Are you okay?" Yubelluna asked making Y/n nod as he stood up with his hole fully healed as it closed up with golden dust. 

"Peachy." He smirked as he crossed his arms as his energy rose.  Pointing at the Fallen Angel Y/n glared at him with his helmet slowly forming. "I'm gonna send you back to Michael." 

"Oh? You can still fight huh child? Okay." He said before summoning a sword. "I'll make sure to permantly put you down. Once I do this I'll send you to the same place as God when he died in the holy war." 

This news stunned the group as Kokabiel smirked. "I'll take your heads even if it means to start another war. Peace is boring." 

"Peace is what? That's why you're starting another war?" Y/n said shocked as he was slowly getting angry as Uria was getting excited.  "You're insane.....YOU WON'T GET AWAY WITH THIS." 

"Don't fuck with me!" Issie yelled snapping Y/n out of his anger. "I'm not letting you destroy this town. Or my friends for some stupid reasons." Y/n looked at his friend as he stood next to him. "Besides....besides that. I'm going to be the harem king!" 

This confused Xenovia as she questioned what she just heard.

"I'm not gonna let someone like you get in the way of my plans." He said causing Y/n to get embarrassed but he let out a soft chuckle. 

"Harem King? Why not just join me. You can have a harem in no time. You can even keep the ones your like." Kokabiel said making Issie shocked.

"Don't tempt me with your sweet words." He smiled making Y/n bonk him on the head as Rias called out his name with disproval. "Sorry I kind of get weak at the word Harem." 

"If you want woman that badly, when we get done, I'll let you do anything you want." This shocked both dragon emperors as Y/n looked with his mouth a gap as Issie had to replay those words in his mind.

"Seriously?" He questioned making him thing of somethings. " then....not just groping, but s...s....sucking your breast, too?" He asked making Y/n look at him with a "wtf" look.

"yeah, it's a small price to pay if we can win with that." Rias said quite embarrassed as she lifted her chest up with her arms a bit before relaxing.

just then Issies balance breaker glowed before shooting out rings of power into the air making Y/n back up as he looked on in nostalgia with the amount of power it's releasing.

Yubelluna looked at her emperor with an idea. Grabbing onto his arm she looked at Y/n with a blush. "My emperor if we win this I'll let you suck on mine." She said as her breast submerged Y/n's arm making him blush before turning bright red. 

"NONONOONO. I'm not like Issie. I mean i wouldn't mind but i want to do that with someone i love. whatamisaying?" he blurted out as his dragon laughed at his embarrassment. But his attention was taken away as Issie sped off towards Kokabiel as he punched the fallen directly in the face making him hold his face in anger.

"Just what are you devil?" He questioned as Issie smirked.

"Listen well, Kokabiel. I'm issie hyudou. I posses a sacred gear that's powered by sex and passion. I'm also Rias gremorys pawn and Ra's champions student!"    

"For such a low level devil to touch my face. You're interesting boy!" Kokabiel smirked before looking at Y/n. "But my fight is with him. Only he can provide me with the best fight. But you are interesting." 

"Is he really that interesting?" A voice called out making everyone look up before the artificial sky was broken by a powerful attack. 

Everyone looked up as a man covered in white dragon armor appeared making Issie shake. 

"Who is that guy?" He asked as Y/n looked up at him as Isabella and Carlamine looked in shock.

"Vanishing dragon!" Kokabiel said as Issie repeated those words with confusion. "Are you captivated by the red and gold, white one. Don't get in my way--" He was cut off as the white dragon emperor quickly appeared and ripped off two of his wings making him yell in pain. 

"What did he do?" Issie questioned.

"I didn't even see what happened." Kiba added making Y/n look at him as if he followed the vanishing dragon.

"Your wings are like a fithly crows. Azazel's are dimmer, more like everlasting darkness." the white one said making Kokabiel glare at him. "It seems like they were burn by a sacred flame as well." 

"Bastard... what are you trying to do?" 

"Someone who's fallen closer to the ground doesn't need his wings, does he?" 

This angered the fallen angel as he summon a massive light spear. "Divide!" but this size shrunk almost instantly confusing Kokabiel.

"My name is Albion. one of the powers of my sacred gear, divine dividing, is to half the power of whatever it touches every 10 seconds, using the power to sustain me instead." 

"Halving the power?" Issie questioned.

"If you don't hurry. You'll lose to even a human." Albion said before looking down at Y/n. "But that was going to happen anyways." 

"The Red Dragon Emperor multiplies it's owners power and transfers it to something, while the White Dragon Emperor halves the attack to sustain it's own power. But the Sun Dragon Emperor is the combination of the two. Just as the legends say." Rias said as she was talking to herself.

 "This is getting boring. I was hoping to have more fun with you." Rushing forward Albion slammed his fist into Kokabiels stomach. "You've been getting out of hand lately. Azazel asked me to bring you back, even if it took all of my power." 

"Azazel!' Kkoabiel yelled as he was dragged around and slammed into the ground by Albion. For everyone it seemed like they landed on the ground. But Y/n saw him getting dragged through the air and slammed into the ground. Upon impact it destroyed not only the seal but also crushed the priest as well.

"Are you going to ignore me, white one?" DDraig asked making the group look at Issies hand.

"You are still alive, red one?" Albions wings glowed as if talking to him.

"These are the conditions we get after we finally meet, huh?'" Ddraig asked wanting a better way of this meeting.

"It's fine. We are fated to fight one day as well. These things happen." the white dragon spoke making those final words sinsiter.

"The red and white dragon emperors." Rias muttered.

"Let's meet again, Ddraig." 

"Yeah, Let's, Albion." 

"Hey what the hell is going on. You stopped me from sucking on presidents breast!' Issie glared but the white dragon emperor simply looked at him.

"Get stronger to understand everything. Become stronger, my archrival, we will fight one day." He said before taking off to the sky in a white light.

Y/n looked up before sighing. "Why did you have to show up now?" Moving towards Issie and slowly out of Yubelluna's chest he crossed his arms. "You now know why I've been training you." 

"Eh?!" Issie looked at him with a shocked look. "You knew about him?" 

"Issie i'm over a millennium years old. Sixty in current time. I've encountered the White one a few times. But he's not my fight." He muttered the last part making Issie look at him with confusion at what he muttered. "Let's go check on Yuto." 

The two walked over to the knight of rias and smiled. Starting a small conversation everyone was having a good time with the small victory. The four onlookers watched as they were having a good time with Kiba having his punishment of one thousand power spankings for acting on his own. 

the next day after school in the research club Xenovia appeared as she was dressed in the schools outfit and to Issie's surprise was also a knight of Gremory. But deep in the mountains Y/n was punching a tree repeatedly as his knuckled bled. 

"I nearly lost myself to them....I nearly lost to Kokabiel. I'm getting weaker, I need to get stronger and stronger to keep my gods world in peace." Spin kicking the tree the massive plant fell to the ground. "Something tells me after the white and red fight. I'll be having my fight next." 

The sacred beasts roar ominously in Y/n's head as his eyes glowed yellow.
