Strongest in DxD - Chapter 63

Two horns started to protrude from his forehead and extended, his hair had grown longer as it glowed emerald green at the same time but two eyes appeared right above his originals as his size increased to close to three meters, his twelve bat wings spread out, bathed in so much power that it could easily be said they could cut through anything as two more huge dragon-like wings sprang from its back.

The monstrous power Ajuka unleashed was making the entire dimension tremble at the power, the earth around him cracking utterly from his mere presence, his body bathed in emerald green as endless magical formulas surrounded him.

He actually looked like what humans would describe as "Demon".

It was the "True Form" of Ajuka Beelzebub.

The "True Form" of Ajuka where his physical abilities increased dozens of times and his magical abilities even more, with this form he gained a power capable of rivaling Sirzechs himself.

Ren just watched in surprise and amazement at Ajuka's form, it was certainly just as impressive, or perhaps more so than Sirzechs's.

Ajuka was strong, overwhelmingly strong, many considered him even stronger than Sirzechs, and far more dangerous due to his unrivaled intelligence.

After the Civil War Ajuka was the first to be considered for the position of Maou "Lucifer", both for his power and for his Intelligence, but he ended up refusing and Sirzechs was elected "Lucifer" due to his power and charisma and Ajuka became the "Beelzebub" only because his friend became the "Lucifer".

Ren smiled as he felt Ajuka's power continue to build.

When Ajuka finished transforming into his demon form, he ran towards Ren. His fist was covered with a unique demonic magic power. This was not a simple energized fist, like most demons. No doubt a blow from that fist could even bring down a major god.

But at that Ren only smiled as Ajuka approached faster and faster.

And when Ajuka's fist was inches from connecting with Ren's face, two words came out of the Sekiryuutei's mouth.

"Shinra Tensei"

When Ajuka's fist was inches from Ren's face he stopped to the Maou's surprise, but it only lasted a second when Ajuka was sent flying violently away.

It was as if a solid wall of air had hit Ajuka and sent him, even in his true form he was sent flying.

As skills worthy of someone of his power Ajuka quickly repositioned and prepared to attack again, but it was too late.

A black rod flew towards Ajuka, cutting through the air, hitting and piercing Ajuka's shoulder.

The Demon King grunted in pain as he felt the weapon pierce his body as he was sent away due to the force of the blow.

Ajuka quickly repositioned himself on the floor while grinding his teeth in pain.

Naturally a simple blow like that wouldn't hurt anyone of Ajuka level, but this shaft was not a normal weapon.

It was a [Black Receiver], one of the abilities granted to users of the [Rinnegan].

These rods were energy transmitters, they could transmit energy from their user, and could only be countered by a user of the [Rinnegan] or the [Power of the Six Paths].

Ajuka widened her eyes as she felt her "True Form" unravel.

These rods had the power to disrupt someone's energy flow, and that's what was being done, Ajuka's demonic power was suffering interference preventing the Maou from manipulating him thus making his "True Form" fall apart.

Ajuka quickly put her hand on the receiver to pull it out, but regretted it when she felt her strength begin to drain away.

As only special people could nullify these rods, they could absorb the energy of any being that touched them.

Ajuka quickly expanded his power to try to pull one of the rods, but Ren was faster.

Before Ajuka could see another four large black shafts, which looked more like spears due to their size, were launched piercing Ajuka's body.

Two hit both legs while the others hit the arms while trapping Ajuka's body.

The Blue Maou totally lost control of his power as the rods disturbed his demonic power causing Ajuka's "True Form" to come undone.

Ajuka spat blood as he felt his own strength drain away, the rods were also totally nullifying his demonic power due to having the power of Ren imbued.

Ren approached calmly while Ajuka was still trying, in vain, to get rid of the black rods that held him.

"So I guess this fight is over," Ren said calmly as he approached smiling.

"Y-You m-damn" yelled Ajuka, letting her calm go as the blood ran down her body.

Ren only smiled as he raised his right hand.

"Well, I'd love to talk to you, but I'm busy so let's get this over with," Ren said with a sigh.

Around Ren's right hand came a large purple com energy that began to increase even more.

Ajuka just stared scared as he felt the overwhelming power that emanated from it.

"This is going to be the first time I've tried this, so feel honored," Ren said holding out his hand.

Soon the ability [King of Gluttony Beelzebuth] activated while the purple energy reached Ajuka and totally devoured him.

All Ajuka could do was widen his eyes as his life drained away.

When the energy disappeared, the place where the Blue Maou was previously had been completely empty.

Ren only smiled as he proved his new skill.

By the time [King of Gluttony Beelzebuth] devoured Ajuka the Sekiryuutei already had Raphael turn him into a [Shadow] while the lifeless body was stored in the ability.

Another thing Ren realized the moment his skill devoured Ajuka was that he gained all of Ajuka's memories, all of his knowledge, all of his experience, all of the thoughts he's ever had.

Raphael had quickly organized everything and discarded the unessentials, leaving Ren with all Ajuka's knowledge of the past few days.

Not only that, Ren had also acquired all of Ajuka's techniques, all of her skills and battle experience, until Ajuka's "Demon Power" had been added for Ren to use.

Even though he was a human he could use Ajuka's "Demon Power" without any problem.

"Raphael, organize the skills and show me the best ones," Ren said calmly.

[Understood]

[Organizing…]

[Complete organization]

[You have acquired the ability "Special Demonic Power"]

[You have acquired the ability "Formula of Kankara"]

[You have acquired a new transformation: "Demon Form; Beelzebub"]

Ren blinked in surprise, especially at the last one.

"Show me a description, Raphael," Ren said calmly.

[Right]

[Name: Special Demon Power]

-Level: Max.

-Rarity: Rare.

-Type: Active.

-Description: All demons, from high class to low class, are able to use this form of power, allowing them to create and control different supernatural phenomena for different forms of combat. There are some unique demonic powers inherited between the different 72 Pillars and the Extra Fiends that no other demon outside of their respective clan is able to use. To use demonic power, it has been described that a demon must first acquire the power of imagination, the power to create, and common sense; however, the main prerequisite for all of this is that it requires a certain amount of demonic power.

The "Demon Power" you acquired is special because it was absorbed from Ajuka Beelzebub, Ajuka's demonic power is unique among demons because it was focused on creation, being specialized in calculations, thus passing to you, Ren.
