Strongest in DxD - Chapter 25

This spell, despite its name, is not completely absolute, as its defensive power is proportional to the user's overall demonic power, as there are individuals who have been able to break through the Absolute Defense with sufficient power.

Sirzechs Lucifer's Power of Destruction is the only thing that can disable it, but the barrier aura can always be regenerated back. It has been said that the only demons that can harm him are Sirzechs Lucifer, Ajuka Beelzebub, Serafall Leviathan and Grayfia Lucifuge (and of course Rizevim Livan Lucifer).

The Angels didn't answer Ajuka and only increased the production of their holy aura causing the demons to squint their eyes.

"Frankly, I bet Gabriel ordered this, the next time I see her I'm going to attack the sky," Serafall said happily.

"…She really hates Gabriel," muttered Falbium to himself.

One of the Angels raised his hand as he pointed to the sky and released an intense amount of sacred energy that formed dozens of spears of light in the sky and fired at the current Maou.

Ajuka took the lead as he reached out his hand and created a green magic circle with various formulas and equations and a green aura filled the spears of light causing them to stop in the air.

It was the [Kankara Formula] of Ajuka.

The [Kankara Formula] allows Ajuka to manipulate the phenomena that occur in the world using his demonic powers to fill in the calculations of natural phenomena. Using a specialized magic circle, he is able to affect the outside world in a variety of ways.

According to Ajuka, all phenomena and abilities in the world have rules and laws, which he managed to get an answer to by filling in the equations. In the past, he had an interest in calculus as a child, and so his demonic powers specialized in these areas.

The moment the spears of light were taken by the power of Ajuka the Blue Maou moved his hand sending the spears of light back to the Angels.

The spears fired at the Angels, the moment Ajuka took control of them he modified them to be impossible for the Angels to dodge and also for them not to be able to take control back.

But that's not what the Angels did.

A literal wall of white flames appeared in front of the Angels, completely incinerating the spears of light.

The moment the demons saw the flames they instinctively recoiled as they felt their body scream in terror and fear at the sight of the flames and also realized how dangerous they were.

These were the flames of [Fire Devil Slayer Magic] that Ren bestowed on one of his Angels.

One of [Annihilation Maker's] main abilities is the ability to grant abilities to the creatures Ren makes, so he was able to grant that ability.

In question, both Angels are at the Seraphim/Maou level but even they wouldn't be able to fight for long against the current Maou.

After all, there were several levels within this class and Ren didn't create them to defeat the Demon Kings.

The flames danced and circled one of the Angels who stretched out his hand making the flames form in the shape of spears and shoot at the Maou.

Ajuka again reached out and created his [Kankara's Formula] but the moment the green energy covered the flames Ajuka's power broke to the Maou's perplexity.

The power of Ajuka, the [Kankara's Formula] allows him to understand all the phenomena of the world in the form of calculations and equations and fill them.

But this is limited to his 'world'.

The flames of [Fire Devil Slayer Magic] even being in the DxD world are originally from Fairy Tail, even though it was adapted for this world it still works by the laws of the Fairy Tail world.

And besides, it is a spell created with the sole purpose of killing demons and therefore can neutralize any attack coming from a demon.

Seeing that Ajuka's power would not be able to stop the flames of her power Serafall raised his wand and waved it releasing an immense amount of ice.

A huge wall of ice created by Serafall's immense demonic power surged forward, crashing into the flames of one of the Angels.

The flames and ice collided and began the dispute for territory temporarily.

Serafall is strong, she is absurdly strong even for a Satan class Demon. Serafall is considered the strongest female demon in the underworld, something that becomes quite remarkable as there are other powerful demons like Grayfia Lucifuge and Roygun Belphegor, who are also known to possess Satan-class powers.

What sets Serafall apart most is her supernatural mastery of ice magic and her immense demonic power.

But inevitably Serafall's ice gave way to the flames that continued to advance

Seeing this Ajuka raised his hand and created a magic circle with his [Kankara's Formula], but it was not in the flames, but in the ice.

Using her demonic power Ajuka boosted Serafall's ice mage who began to battle the flames.

Seeing this the other Angel raised his hand creating dozens of spears of light and it rained against Ajuka and Serafall who were too busy to do any.

But before he could reach Falbium he advanced and using his [Absolute Defense] completely nullified the light attack.

Seeing that his spears alone would not be enough, the Angel reached out his hands and created two swords of light and advanced.

Seeing this Falbium increased his demonic aura and charged the Angel.

Both began to fly across the battlefield releasing waves of holy and demonic energy.

No matter what attack of light the Angel made the [Absolute Defense] of Falbium would deny.

As they both struggled and clashed Falbium smiled as he felt his power increase, Falbium deciding to end it changed his [Absolute Defense] to [Offensive Position] form.

Offensive Position is a technique created by Falbium where its defensive barriers are able to absorb any and all attacks and carry kinetic energy that would allow it to counterattack with its demonic power.

Raising his right hand Falbium focused his orange demonic aura concentrated and unleashed a huge blast of demonic energy.

Seeing the attack coming the Angel raised his hand creating a huge sword of light made of holy energy and cut the attack in half.

But at that very moment Falbium was already in front of him and he lit his hand with its power and released it in a huge orange ray.

The ray of orange demonic power surged across the entire path in a single instant as it hit the Angel that was sent flying before the energy exploded into a huge sphere of orange power that lit up part of the underworld.

Seeing that the Angel had been exterminated Falbium returned to help his companions.

Ajuka and Serafall released their power while surprisingly being suppressed by the Angel's power.

However the huge explosion made by Falbium distracted the Angel and Ajuka and Serafall released their powers that advanced against the Angel suppressing the flames due to the Angel's distraction.

The [Fire Devil Slayer Magic] belonging to the Angel was only a fragment of power compared to Ren's.
