Ajuka Beelzebub was the current Demon King Beelzebub. While he was not of House Beelzebub, he was chosen alongside his friends, Sirzechs, Falbium, and Serafall to become a Demon Lord. Of course, Ajuka could care less about being a Satan. The only thing he cared about was inventing and tinkering. And for this reason, only a few people have access to his lab. Sirzechs, Serafall, Falbium, and Sirzechs and Serafall's sisters. He had experience in watching over the two hellions when they were smaller whenever the Lord and Lady Gremory or Lord and Lady Sitri went on a personal vacation.

So when his lab's entry alarm went off, he immediately recognized the demonic signature that arrived.

"Rias? What's she doing here?" Ajuka asked himself.

His answer came in the form of Rias and her peerage bursting into his lab with an unconscious Issei. His eyes widened when he saw first degree burns from Holy Energy on Rias's arms.

"HELP HIM!" she demanded.

"What? What the hell happened!?" Ajuka asked, checking over Issei. He placed a hand on Issei's forehead. Upon making contact, he immediately retracted his arm. "Holy power. But what…? Even if the rituals didn't work, Ascalon isn't capable of producing holy power this potent."

"We don't know what's going on. Issei just got worse over time! And this idiot kept refusing treatment!" Rias said. Her breathing became more rapid and hysterical.

"Right. Kiba, go to my lab and get me the box labeled medical and surgical equipment. Koneko, I need a bed. Akeno, Asia, I need you here to stabilize Issei while I get things ready. Rias, keep him calm and… you?" Ajuka's eyes landed upon Mitsuki. Who is she? Whatever… "You hold him down. In a few seconds, Issei is going to experience a Holy Cascade and will begin thrashing around in pain."

Everyone nodded and ran to perform their respective duties.

Issei ran. He ran for his life. He was fighting for his own life inside his own body. And for once, it wasn't because he was sick. It was because of this insane asshole who apparently came with the Divine Dividing's gem.

Anastacius had harped to him about the humiliation he suffered at some lady named Elsha, who was one of the previous wielders of the Boosted Gear. And now, since Issei possessed the Boosted Gear, he was a target for his vengeance.

Anastacius flew high into the air. The wings of the Divine Dividing pulsating brightly behind him. He raised his hand and summoned several blue magic circles.

Blasts of energy the size of cars flew from them at high speeds, all seeking to vaporize Issei to ash.

"Ddraig! Ddraig!" Issei called out.

[Boost]

Issei summoned the Boosted Gear.

"Where the hell were you!? I've been calling for you for ages!" Issei yelled.

[This is a part of your mind that is hard for me to access. You letting me in made it easier for me to contact you and lend you power.] Ddraig said. [Hmm? It's that White Dragon Emperor that lost horribly to Elsha. If I recall, he's on the lower tier of White Dragon Emperors that I've fought over the years. I'm pretty sure he's part of Albion's dark past as a Longinus Gear.]

"We're in the middle of a fight here!" Issei yelled.

[I can see that!] Ddraig replied.

[Boost]

Issei spun around and turned to face the previous White Dragon Emperor.

"Eat shit pretty boy!" Issei yelled. He pooled demonic power to the palm of his hand and fired it at his foe.

|Divide|

"Ahahaha! Did you really forget what the Divine Dividing could do?" Anastacius mocked. "Was your victory against this generation's White Dragon Emperor just a fluke? Whatever… it doesn't matter," he said. Anastacius dove towards Issei, creating several sonic booms in his wake. In Issei's vision, the man had become a streak of light barreling towards him.

[Partner! Here he comes!] Ddraig said.

"I can see that!" Issei replied. He raised his arms to block the punch that Anastacius had ready. The force of the punch was so immense that Issei almost felt his arms snap in two.

He was sent sliding back across the field. "Holy fuck! That hurts!" Issei groaned, rubbing his arms.

[Boost]

If only I could use the Balance Breaker, Issei thought. He powered up and charged at Anastacius, cocking his fist back. He channeled his boosted energy into his fist and swung.

Anastacius lazily moved to the side, dodging Issei's attack easily. He raised his foot and kicked Issei back, sending him rolling across the field.

"Damn," Issei said, shakily getting to his feet. The gap between him and the previous White Dragon Emperor was vast. How could he possibly even afford to win against him?

[Don't even think of giving up, Partner. Our pride as the Red Dragon Emperor is on the line. Do not lose to the White One. Especially a ghost of the White One!] Ddraig urged.

"I got it… I got it… It looks like, we'll need to kick things up a notch," Issei replied.

[Boost]

[Blade]

The blade of Ascalon extended from Issei's Boosted Gear gauntlet. The mere sight of it made Anastacius freeze. A dragon slaying weapon? Whatever… he doesn't have enough power to challenge me. With him gone, I can finally avenge the humiliation I suffered at the hands of you, Elsha. Are you watching? I will kill your successor! Anastacius grinned and charged toward Issei.

[Boost]

Issei felt a rush of power flow through him. He dug his heel into the ground and took off in a burst of speed. His eyes locked onto his opponent. He dodged the punch and countered with an upward slice.

Anastacius screamed, feeling the searing pain inflicted by the dragon-slaying sword. He jumped back and fired several energy blasts at Issei.

Issei zigzagged, weaving through the volley of blasts. "Hey, asshole!" Issei unfurled his wings and flew at breakneck speeds towards Anastacius.

Anastacius's eyes widened when Issei's skull rammed into his. He howled in pain, gripping his head as he struggled to remain airborne.

"Stay down!" Issei yelled. He appeared above Anastacius and drove his elbow into his skull.

Anastacius felt his vision fade to black for a few seconds before finding himself impacting the ground beneath in a brutal fashion.

"Haaah!" Issei slammed down on the downed White Dragon's torso, shattering the man's ribs and knocking the air out of him.

Anastacius let out a soundless gasp and began coughing up blood violently. He rolled to the side, curling in on himself and gripping his stomach. "B- Bastard! I won't be humiliated again! Especially by you!" he groaned.

A surge of draconic power exploded from Anastacius, pushing Issei back. The ground shook violently as he rose into the air. He raised his hand into the air. A 30-meter-tall sphere of magical power appeared over his head. He threw it at Issei.

Issei gritted his teeth.

[Boost]

Issei jumped into the air, dodging the blast. The sphere ruptured, creating a massive explosion that bathed the world in white light. The force of the blast knocked Issei out of the air and sent him flying hundreds of meters into the distance.

"DIE!" he screamed, firing another blast of energy at Issei.

Issei righted himself in midair and swung Ascalon at the blast, sending a wave of dragon-killing energy at the energy blast.

The slicing wave cut the energy blast in twain, producing another sonorous explosion that shook the entire mindscape.

"Raaaggghhh!"

"You! Hold Issei down!" Ajuka yelled.

Mitsuki nodded and forced Issei's hands down. Koneko ran up and helped restrain him.

[Boost]

The Boosted Gear suddenly manifested itself in Issei's arms. The black veins on Issei's body began to throb and pulsate even harder, exuding waves of holy power. Ajuka gritted his teeth and cast a protective power around Rias's peerage, protecting them from the effects of the energy radiating from Issei's body.

The EKG to their left began to beep frantically as Issei's heart rate began to rise into the 200s.

"Damnit! Kiba, get me the holy extractor now! I need to extract all this holy energy from Issei's body or else it'll incinerate him from the inside out and he'll explode!" Ajuka ordered.

Yuuto nodded and rooted around inside his equipment. "What does it look like!?" Yuuto asked.

"It looks like a drill with a canister attached on top of it! Hurry now!" he urged.

Yuuto pulled it out and handed it to Ajuka.

"Hold him down while I insert the needle into his chest!" Ajuka said.

The Gremory Peerage all gathered around Issei and struggled to keep him still. Issei's rising power, coupled with the increasing amount of holy power coming from his body was making it hard for them to do anything. Ajuka stood over Issei, casting a magic spell that bound Issei's torso to the bed. "Keep his arms still."

Ajuka inserted the needle into Issei's chest. The canister began to immediately fill with red energy.

What the? This holy power! There's so much! Damnit, Michael! What aren't you telling us about Ascalon… or is it even Ascalon that's doing this in the first place? Is the Divine Dividing's Gem doing this? He thought as the energy continued to fill up.

"Damnit! Yuuto! Go get me another canister! This one filled up too fast!" Ajuka ordered.

Damnit! Issei! What the hell is going on with you?

Issei and Anastacius clashed in mid-air trading blows with each other. The previous White Dragon Emperor could not believe what he was seeing. This brat. This Red Dragon Brat was fighting on par with him. This was inconceivable. This was unacceptable. This was completely and utterly impossible.

"Raaggh!" Anastacius slammed his fist into Issei's torso, knocking the air out of him. He rose over Issei and spiked him, sending him crashing into the ground below.

He divebombed towards Issei, intent on completely smashing him to paste.

Issei's eyes widened and he rolled out of the way, dodging the attack of the Previous White Dragon. The ground exploded, producing a massive crater the size of his entire neighborhood block.

He quickly got to his feet and rushed towards the White Dragon Emperor, using a combination of his fist and swiping motions with Ascalon to get the upper hand on him.

But Anastacius was getting used to Issei's rudimentary thrown together fighting style. He could see the openings, weak points, and flaws in his technique. He parried one of Issei's attacks and kicked him back. He rushed towards Issei and slammed a ball of energy into his chest.

However, Issei anticipated that move. He swung his blade upward, inflicting a deep wound in Anastacius's chest.

"Bastard!" he screamed. He uppercut Issei, sending him into the air before grabbing his leg and smashing him over and over again into the ground.

Issei coughed, spitting blood from his mouth after the last slam that ruptured the floor beneath.

"I'm not going to hold back anymore. This time for sure! I will avenge myself and destroy you!" Anastacius roared.

|Vanishing Dragon Scale Mail|

Issei got up slowly, watching a veil of light brighter than the sun enveloped Anastacius.

Anastacius let loose a burst of energy potent enough to level half of Kuoh Academy in a single burst. White armor covered his entire body. A visor with the design of a dragon's head covered his head and the wings of the Divine Dividing became larger and more prominent. A segmented mechanical tail extended from his back.

"Tch! What the hell? How are we supposed to win now, Ddraig?" Issei asked.

"You can't."

Issei's eyes widened when he saw Anastacius standing right next to him. With one swing of his arm, Issei was knocked back down, hitting the floor face first.

Anastacius grinned behind his visor. He reared his head back and kicked Issei in the ribs, sending him rolling across the ground.

Issei groaned in pain, feeling his skin getting torn open by the friction. Blood poured down his head, mouth, and arms. There wasn't a single part of his body that didn't hurt. He glared at the previous White Dragon Emperor. The man's power had increased significantly after entering the Balance Breaker. And with his entry into Balance Breaker, the man's arrogance had returned tenfold. The look of superiority in his eyes was beginning to annoy Issei. But… he knew that he could back it up. The power he possessed was more than enough to prove that he was now stronger than Issei.

And Issei knew that no matter how many times he boosted his own power, there was no possible way to bridge the gap between the two. He needed a miracle to happen. Issei glanced at Ascalon.

Maybe if I boost Ascalon's power, I might have a chance at beating him but that chance is one in a billion, Issei thought.

But that's all I got. You with me Ddraig? Issei asked.

[If only you could access the Balance Breaker at this time… we would have been able to wipe the floor with him.] Ddraig lamented.

"Heh, well, I ain't dying here. Not by a longshot. I haven't even sampled all the tits in the world yet," Issei said, getting up.

[As embarrassing as that goal sounds, I guess if it motivates you, we'd have no other choice] Ddraig said. [Let's show this asshole what it means to be the Red Dragon!]

"What are you blathering on about down there?" Anastacius asked.

"Nothing much," Issei said, smirking.

[Explosion]

Red aura erupted from Issei's body and governed him entirely. His power dramatically increased to the point where he began generating gale force winds.

[You can control Explosion far better now, Partner. The time limit for unleashing all your stockpiled power is about 15 minutes. And you've stacked on about 50 or so boosts.] Ddraig informed.

"Got it."

Anastacius tilted his head. Explosion. That power was one of the base powers of the Boosted Gear. While it was no Balance Breaker, it served as a good substitute for its base form. He raised an eyebrow in confusion, however. In what way was this going to help?

Issei let loose a burst of power. The ground underneath him splintered and rocks levitated into the air. With a mighty beat of his wings, Issei shot towards Anastacius in a surprising burst of speed.

His speed caught him off-guard, allowing Issei to land a devastating blow to his torso. Issei ground his teeth together before letting out a battle cry.

"DRAGON SHOT!" Issei roared. A blast of red energy exploded from Issei's hand and slammed into Anastacius. He channeled the Dragon Slaying properties of Ascalon into it, allowing his Dragon Shot to shred Anastacius's midsection like paper.

The beam pushed Anastacius higher into the air before exploding in a massive ball of fire.

"I'm not done!" Issei yelled. He jetted towards him, shattering the sound barrier several times over. He appeared above Anastacius's stunned form and performed an ax kick that sent the man slamming into the ground with the force of a comet.

"Take this!" Issei dive bombed towards him.

"Hah… is that it?" Anastacius asked.

Issei's eyes widened upon hearing his words. He moved to evade Anastacius's next attack but failed to. The sickening sound of his ribs cracking and his sternum fracturing filled their surroundings. Issei flew into the air, launched away by the White Dragon Emperor.

Anastacius flew at Issei at full speed, far surpassing the speeds he was capable of. He blitzed Issei, landing multiple blows and flaying his flesh. He appeared in multiple places at once, using the capabilities of the Divine Dividing to allow its user to travel at the speed of light.

He appeared above Issei and drove his armored elbow into the small of Issei's back, stunning the boy and slamming him brutally into the ground.

"Ahhh!" Issei howled in agony as he felt the pain course through his entire body.

Anastacius grabbed Issei by the back of his head and held him out in front of him.

[Partner!] Ddraig yelled.

Anastacius punched Issei in the kidney, sending another wave of pain through the boy.

He repeated this act of brutality, punching Issei over and over in the kidney before letting him go and kicking him away.

As Issei rolled away, Anastacius appeared and kicked Issei into the air before punching Issei in his injured torso, slamming his armored fist into Issei's liver.

[Damnit! Partner!] Ddraig screamed.

Issei's eyes snapped open and he managed to twist his body to deliver a devastating kick to the side of the Past White Dragon Emperor's armored skull. The blow cratered the ground beneath them and sent Anastacius stumbling.

"Insolent fool-"

His words of rage were cut off by the sight of Issei's face slamming into his visor and cracking it.

"Haaah!" Issei rushed to him and landed a flurry of blows all across his body. His rage and desperation to survive had given him his second wind. He jumped back before charging forward, driving his elbow into Anastacius's liver and then performing an uppercut.

"I'm not gonna die! I will get back to them! To Buchou! To Asia! To Akeno! To Koneko! To the Cassanova! To Gasper! To Xenovia! And finally to Rin and Mii-chan!" Issei roared. He performed a spin kick that sent Anastacius face first into the ground.

"GO TO HELL!" Issei roared, creating another Dragon Shot.

|Divide|

Issei's eyes widened when the Dragon Shot vanished.

|Divide|

"No!" Issei yelled, feeling his power rapidly disappearing. "Piece of shit!" Issei said, kicking Anastacius away. He jumped back, gaining distance between him and his opponent.

"Hehehe, that was good. I would've been disappointed if you were just going to go down like that," Anastacius said.

"Tch!" Issei tightened his jaw. That bastard sapped over half of my remaining energy and his energy is still high! And Vali is supposed to be strong? This asshole hasn't even hit his ceiling yet!

"I think it's time we end this right?" Anastacius said. "I'm done dragging this out."

"W- What?" Issei clenched his fists. There was no way he was going to die. Not like this.

Ddraig, I'm going to use the Dividing Gear, Issei said.

[Normally I would respond with a no but… in this situation, I'd rather see you alive with a shortened lifespan than see you dead at the hands of one of the White One's past hosts.] Ddraig said.

Issei summoned the Dividing Gear to his right hand.

"Oh?" Anastacius said. "You do know that will sap your lifespan, right? If I recall, your body is rejecting the Dividing Gear and is currently dying as a result of fighting against its presence."

"So? Even if it means having only a few more days left to live, it'll all be worth to kick you out of my mind," Issei said.

"Fine then! Let's finish this, Red Dragon!" Anastacius charged towards Issei.

Issei kicked off the ground and flew at breakneck speeds towards his foe.

"RAAAGGGHHH!" Issei's back arched off his bed, sending waves of power across the room. Several of Ajuka's lab equipment shattered as they all held him down. The Dividing Gear manifested in Issei's right hand, calling their attention.

"Just hang on, Aniki!" Mitsuki yelled.

The two fighters threw their punches, impacting their respective opponent's face at the same time. They flew apart before darting back in and traded blows in a vicious dance.

Issei ducked underneath a punch and threw a haymaker using his right hand.

|Divide|

Anastacius felt some of his power leave him. "You…!"

Issei punched Anastacius again, sending him stumbling back.

"YOU DARE USE MY OWN ABILITIES AGAINST ME!?" he roared. He charged back in, ducking underneath the Dividing Gear and headbutting Issei in the chin.

Issei was sent staggering and it allowed Anastacius to land a flurry of blows across his body.

As Issei was being pummeled with punches and kicks, he lashed out, countering with a kick to Anastacius's injured ribs.

"Ddraig! I need more power!" Issei said, tackling Anastacius to the ground. He sat on the man's chest and began to rain blow after blow down on the man's skull.

[Boost]

He summoned Ascalon's powers, channeling them into his fists as he continued to rain blows.

With one mighty roar, Issei slammed his fist straight into his opponent's face, shattering the visor in one blow and breaking his right orbital.

"You… You insufferable runt!" Anastacius yelled. He grabbed Issei's fist before quickly rising and throwing him off.

Before Issei could get up, Anastacius grabbed his leg and threw him into the air. He flew up, punching Issei repeatedly in his injured ribs, rising higher and higher. He suddenly wrapped his arms around Issei, enveloping him in a bear hug that was crushing his already broken ribs and injuring Issei's injured spinal cord.

He then turned around and dove towards the ground, intent on slamming Issei first and using him as a cushion. They impacted the ground violently, sending dust and large fragments of the ground everywhere.

Issei let out weak breaths, lying at the center of the crater. Anastacius stood above him, panting heavily.

The older man grabbed Issei by the throat and lifted him into the air.

"It's over and now, I'll sap all your power until you're nothing more than a husk and then, I'll tear you apart limb from limb," Anastacius said darkly.

"Fuck you," Issei said.

Anastacius only grinned.

|Divide|

Issei felt his power growing smaller and smaller. Soon, he wouldn't have any energy left to even speak or keep his eyes open. His life was slipping away and he could feel it.

The heart monitor began to beep wildly.

"Issei's crashing!" Ajuka yelled. "Asia!"

"R- Right!" she said. Asia activated Twilight Healing and began healing Issei, trying to keep him stable for as long as possible.

F- Fuck… is this how I'm really going to die? Issei thought, feeling his vision grow darker and darker. He could faintly see the victorious, arrogant smirk of the previous White Dragon Emperor.

I'm really sorry everyone. Ddraig, Buchou, Mii-chan. I'm sorry…

"You look like you're in a lot of trouble there, Ise-chan," a voice suddenly said.

What… Who's-

"Nevermind who's there. It's too early for you to go, Ise-chan. Live a long and healthy life with the people you love."The voice sent soothing waves of energy through Issei, numbing the pain. "I guess I'll help you just this once. I'm just about done doing what I need to do so… go forth and wield the power you've been deprived of for too long, Ise-chan~!"

Who… Who are you? Issei asked.

"It's too early to meet me, Ise-chan. But just know that I'm the voice in your head and I'm also your guardian angel~!" the voice said.

Alright then, Angel-san. If you insist… wait, what do I even do? He asked.

"Leave that to me~ !" the voice said.

"What's wrong boy? What are you mumbling to yourself?" Anastacius asked.

The Dividing Gear in Issei's right hand suddenly began to glow brightly. The once blue gem turned blood-red and the white began to vanish and was dyed in a pitch black hue. The red gem glowed brightly, blinding Anastacius in the process and forcing him to drop Issei.

Issei coughed violently but began to feel better. He was healthier, stronger, and faster than he was earlier. He was being returned to his top settings.

"Let no one stand in the way of your grand rebellion against your fate. Wield your iron will and become the Opposition your opponents shall never overcome," the voice said.

"Opposition… that's a good name. That's what I'll call this from now on," Issei said, holding the black gauntlet in front of him.

"W- What? Where did you get all this power from!? WHERE!?" Anastacius charged at Issei.

Issei ducked under the punch and dug his right fist into Anastacius's liver. Using Ascalon's dragon-slaying powers, Issei punched right through the armor and dealt immense damage to his foe.

"A crash course for now in one ability you'll find useful, Ise-chan~!" the voice said.

Issei felt a rush of instinctual knowledge rush into his head.

"T- This is…"

He felt the voice in his head smirk at his words.

But… how? Well… questions for later. I'm not going to look a gift horse in the mouth! Issei thought.

"Hey! Bitch-face!" Issei yelled. He channeled demonic power into his legs. His speed increased drastically and he practically teleported to Anastacius's position. "Go eat shit in hell!" Issei yelled.

Black energy formed in the palm of Issei's hand. Issei instinctively knew what to compare this to. The Power of Destruction so he stuck to calling it that. The black orb of energy spun rapidly in his palm as he thrust it forward to an unsuspecting Anastacius. The orb hit home, immediately grinding away at his exposed flesh.

"Haaaaaahhhh!"

The shade of the previous White Dragon Emperor howled in agony as the orb rapidly expanded and consumed him. Issei pushed, firing the orb into the distance.

The black orb exploded violently, sending waves of heat and wind over Issei.

Issei panted. He fell to his hands and knees, feeling the energy leave him all of a sudden.

"T- Thanks," Issei said.

[Eh… you're welcome, Partner.] Ddraig said.

"Huh? I meant the other person," Issei said.

[What other person?] Ddraig asked.

"The other…" Issei didn't finish his words when he felt a rush of fatigue wash over him. Strange, he wasn't tired enough to pass out so why was he…?

"Like I said, it's still too early for us to meet. Let's talk again when you're finally ready, Ise-chan," the voice said.

Issei looked up, eyes about to fall shut. The last thing he saw was the silhouette of a woman walking toward him and gazing upon him with her mismatched eyes.

To KnightMars: Why thank you! I hope you look forward to even more chapters I have planned!

You know... in order to prepare for this fight scene, I watched the entirety of DBZ Kai all over again. I don't know why I picked it. I was feeling nostalgic one day and just decided to binge the entire series again. All the way up to the Majin Buu Saga. Anyway, a relatively shorter? note on this chapter compared to the others. But I'll explain what's going on here. If any of you read or watched Highschool DxD, you would know that in Volume 4 or at the end of Highschool DxD New, Issei absorbed the Divine Dividing Gem, and in later volumes... Azazel banned Issei from using Dividing Gear because it ate too much of his lifeforce. So... I decided to have Dividing Gear reject Issei and attempt to kill him from the inside out, causing his body or well, her to fight back and the clash of dragon energy and... well holy power was beginning to kill Issei from the inside out. The illusions were amped by outside forces.

So yes. No gimmicks regarding the Evil Pieces. Just me warping the outcome of Issei absorbing Dividing Gear.

So the volumes will have Arcs inside of it.

Volume 1 is called Special Children and will have 2 Arcs:

Arc 1: Altered Beginnings

Arc 2: The Lord of the Flies

So that's what I have planned so far... at least what I'm telling everyone what I have planned so far.

Anyway, leave a review. Follow! And I'll see you later.
