As a Lucifer in DxD

Ajuka POV

I have always considered myself a genius. Even my friend Zeaira was stronger than me not smarter than me. But my way of seeing the world changed when I first saw him demolishing Sera without even trying.

Cain Livian Lucifer was undoubtedly the strongest devil around. Zeaira may think she is stronger but deep down I know she will lose to him.

The way he carries himself is scary. No wasteful movements, always observing everything around him, ready to react in a moments notice. First time I knew it was when he killed those invisible insects.

Seeing him made me want to have a trump card strong enough to give him hell. I wanted to control all the phenomena and abilities in the world.

My father told me I was a transcdent devil. I only knew the horrors of them when I read about them and finally met them. My father and mother always told me hide my power and not to let the satan know about it.

But all of that went down the drain when Zeaira stepped forward to help the Oriax heir. Which led to the tournament and all four of us reveling our powers.

Maybe this made the satans feel threatened starting the civil war or maybe it did not, but I know for sure the devils need to change for surviving.

I may not be able to help much in politics and outer affairs as I have no interest in those things, but I will do my best to use my passion and talent to help the devil race.

When I awakened my clan trait I was ecstatic but I only got the formula part and not the seals part. But I was happy from a young age I had a intrest in calculations this made my demonic energy have a special trait for magic circle creation.

My specialization laid in a branch of creation the stark opposite of my friend Zeaira who was specialized in destruction.

After decades of failed formulas, thousands of experiments I finally managed to reach my goal the absolute formula.

Kankara Formula, It allows me to to manipulate the phenomena that occur in the world by using my demonic powers to fill in the calculations of the natural phenomena. By using a specialized magic circle, I am capable of affecting the outside world in various ways. 

I never ever had the opportunity to use it in combat but thanks to the Civil War and Cain I got this golden opportunity.

Although it may be wrong to think of this war as a good thing my inner mad scientist can't help but be excited at the prospect of using my crystallization of knowledge practically.

I stand infront of Tsufaame Tereaku Leviathan and flying above the retreating armies of the satans and anti satans faction leaving the already ruined Gusion castle even more damaged.

The Gusion clam went extinct during the Great war. 

But now the time has come to fight a satan descendant. Multiple things are at stake. I must win for my clan, for the devil race and most importantly for the sake of my calculations.

...

Third person POV

Just before the attack at the Gusion castle. Cain had just came back from Nyx's divine realm. She had gotten weaker over the past dcades making Cain hasten his plans for making Hell.

'I also need to put the six houses of the lucifer in place. Though Lucifuge can get a pardon can't really blame Gerhard and Grayfia is my maid too.'

While Cain was thinking this Grayfia came to him and said in a urgent voice 

"My lord according Falbium there has been movement by the satan faction and they have attacked our base at Gusion castle. It seems that the Leviathan is the one leading it."

"So finally after 6 months of back and forth they decided to get on the offensive. Tell Ajuka to go there and help the soldiers retreat. Also let him decide the fate of the Leviathan."

Cain wasn't really worried although he didn't expect Tsufaame to come. In terms of top tier powerhouses the anti satan faction has the upper hand.

As for Ajuka he was saying about testing his trump card so he let him go.

'Let's see how does the current Leviathan fair against the future Beezelebub.'

...

After Ajuka was informed of the task by Grayfia he immediately teleported inside the Gusion camp which was in chaos. 

They had heard that the satans were coming here. They had lost all hope. Ajuka first asked the highest ranking officers to gather and shut up every soldier by using his aura.

After they were calm he asked about the situation.

"Lord Ajuka we don't even have any satan rank devil here. But this position is very important from the strategic point of view both Lord Cain and Lord Falbium had said it."

Ajuka naturally also knew about it but he couldn't guarantee that this place will be habitable if he fought here. So he asked then to leave this camp to him and go make a large scale formation around the Gusion town. 

"May I ask why my lord? We should retreat after all the Leviathan is coming."

"Leave the Leviathan and the generals to me. Just focus on killing the enemy soldiers." 

Saying that Ajuka spred his wings and went high up in the sky waiting for Tsufaame to come to him.

The camp leader looked at Ajuka and doubted him but followed the order regardless. He emptied the camp alongwith all the good they could have carried in a moments notice and formed a formation ready for battle at 500 kilometers around the Gusion town.

Ajuka had told them to also stop anyone from interfering in the battle that was about to happen.

...

Ajukas troops initiated the battle with the Leviathan troops centered around the Gusion domain. In a few moments Ajuka killed all of the generals of the opposing army making the leviathan enter the battle.

Tsufaame used her devastating abilities to destroy the troops of Ajuka but he managed to redirect the attacks giving the army enough time to retreat to safety and continue their battle with the Leviathan army.

"Leviathan, it seems we've come to this point. Are you ready?"

Ajuka asked maintaining his calm demeanor

Tsufaame said while smirking arrogantly

"Ready? Astaroth, my power far surpasses yours. This battle will be over before it even begins."

"Is that so? You satans always had quite the ego. But remember, it's not just power that wins battles. Strategy and intellect play a significant role."

"Strategy? Intellect? You were the bookish type I heard, Astaroth. But when it comes to raw power, there's no contest."

"Raw power can be impressive, but it can also be a double-edged sword if not wielded wisely. My friend is also of the same type."

 "Oh, don't worry, Astaroth. I fully intend to win, and when I do, you'll finally understand who the superior devil is."

With that both the devils got ready and unleashed their auras.

Tsufaame used her clan trait Sea serpent of the end to use the water of the nearby lake to create water creatures and attack Ajuka.

Ajuka manipulated them using his kankara formula and turned them against her own troops creating chaos.

The Leviathan was shocked that her attacks which were strong enough to kill ultinare class devils were handled with ease by Ajuka.

Seeing this Tsufaame got angrier and started using attacks which could drown entire cities. She started using her own demonic powers to create water and use it against Ajuka but he was still handling without any problem.

Due to not having any prior combat experience of fighting someone much stronger Tsufaame burned through her reserves very quickly.

Very soon she was grasping for air while Ajuka wasn't even tired. In this entire fight he had only used his Kankara formula to take control of Tsufaame's water and use it against her and her army.

This shows how good of a control he has over his own demonic power and other using his formula.

Ajuka turned her water blasts into mist to dissipate them, turned her water beasts back to water and redirected her attacks back to her.

Using kankara formula he took control her attacks and calculated to alter then in such a way that the Leviathan cant disable them.

"Curse you Lowly Astaroth! How could you be stronger than me a pure blooded satan."

"Bloodline means nothing if the person who has is not good."

Hearing that Tsufaame got angry and her demonic power started going haywire. She transformed into a giant serpent like dragon that was the true form of the Leviathan. 

Also known as the serpent of envy. She started firing gigantic aura beams at Ajuka in her frenzy.

Each of those beams was enough to destroy the armies, multiple of those beams can even completely destroy a country.

Tsufaame had lost all reason due to her transformation being induced due to rage and not of her own will.

Ajuka using his Kankara formula turned her attacks on her own her army destroying them, he directed the rest beams away making giant explosion.

The craters created were enough to contain water from hundreds of lakes.

Seeing that the rampage of the Leviathan will bring great destruction, Ajuka got serious and used his kankara formula to the limit.

Ajuka was not like Zeaira or Cain who transformed into their super devil forms. He didn't have one. When he used his kankara formula to the max he could control everything under a certain radius regardless of abilities and phenomena.

The was his super devil power. In his domain he is the supreme being. He can control the energy of his opponent without his consent. Basically any phenomena and ability inside his domain are his to use with the same proficiency or even higher than the original user due to Ajuka being smart enough to understand his opponents power better than them.

There are certain exception like someone who had better control, is way stronger or has an technique to counter it. But regardless due this outrageous ability Ajuka has earned the right to be called a Transcendent devil.

Every natural phenomena in the vicinity of Gusion town stopped. Even Tsufaame was unable to move. Only Ajuka was able to. After that Ajuka created a magic circle and touched Tsufaame.

Just by that touch she transformed back to her normal form. 

And fell down to the ground. Ajuka took control of her clam trait and reversed it. As it was his first time he needed to touch otherwise he can simply do it from far away.

Ajuka released his domain and came down to see Tsufaame kneeling on the ground with a look of despair and denial on her face.

Ajuka seeing that he offered her a chance to surrender. But She laughed and said

"Surrender I will treated as a livestock for breeding if the first gen devils get their hands on me. I know how precious my bloodline is."

"I can personally guarantee that you will treated rightfully as a prisoner of war. If you behave you can go back to your position after the civil war is over."

She refused with the words "I, daughter of Leviathan, shall never surrender to the likes of you! You scum!" putting her class, reputation and honor over her own life.

Seeing that Ajuka sighed and replied "I'm sorry. But the Underworld doesn't need you."

Saying that Ajuka pierced the heart of the Leviathan using his pure condensed demonic energy as a sign of respect.

This feat was achievable only by a few in the entire devil race again demonstrating how big of a monster Ajuka is beneath that calm demeanor.

Thus the battle at the Gusion castle ended with a win for the anti satan faction and a tremendous loss for the satan faction.

...

The news of the death of the daughter of the Leviathan spread in the underworld quickly. Making known that the anti satan faction has devils strong enough to contend with the satan faction.

This boosted the morale of the rebel troops to another level making it even harder for the satan army to fight evenly with the rebels.

All the devil lords congratulated Ajuka and some even offered a marriage offer. But Ajuka kindly declined all of them politely. He had already known this would happen if he showed his strength.

In the other hand Cain was still easy going. He had sensed the battle between Ajuja and Tsufaame.

'To think he could have the power to completely shut all phenomena within his domain and cut of space from outside.'

Even Cain would be in a pinch if he had to fight Ajuka. But he would be fine as he had near perfect control over his demonic energy and darklight will win in a long battle due to its effects.

And so this stalemate with the rebel faction on the winning side will go on for a while until another satan joined the battle.

For planning the future invasion of Lucifaad which Cain had left after transferring everything from his castle to the wealth using the magic embedded in it to Lilith. Cain had done this as he knew Lucifaad will not the capital after the civil war.

Cain had called a meeting with the devil pillars and the four rookies as he liked to call them though that had been in the past.

This meeting will decide how to deal with the remaing satans and the six houses of lucifer alongwith the devil pillars that still support the satan faction.

AN:- Sheesh! You guys are killing it with the support. At rate I will have to post a fourth chapter this week.
