Gilgamesh in DxD

"Are you going to hit yourself too?" cried Sirzechs in astonishment.

Gilgamesh only smiled calmly, "I have several ways to defend myself, but what about you?"

Sirzechs' eyes quickly turned to the meteor that was falling on him, and increasing its power Sirzechs' [Power of Destruction] exploded.

An immense crimson aura exploded from Sirzechs' body, this intense aura condensed on the hands of the Crimson Maou who raised them.

The ground around Sirzechs disintegrated due to the sheer destructive power being released, and Gilgamesh was able to see that space itself seemed to be collapsing due to the crushing power of the Crimson Satan.

Sweat dripped down Sirzechs face due to the strain of being releasing so much power at once, something he was not used to.

The crimson aura gathered in Sirzechs' hands as it condensed into a huge sphere of pure [Power of Destruction].

Expanding its power the pure sphere of destruction advanced against the meteorite.

The sphere of destructive power crashed into the huge meteorite as both generated a huge shockwave upon impact.

Although the meteorite possessed an enormous destructive capacity, one could not forget that it was a simple, gigantic stone, and upon coming into contact with the abysmal amount of [Power of Destruction] it was being annihilated.

When the [Power of Destruction] totally consumed the meteorite, it exploded, generating an immense shockwave that caused the entire battle arena to shake.

Gilgamesh only watched calmly from the protection of his [Susanoo] as he waited for the cloud of dust that had been raised to break up.

And when it broke apart, the King of Heroes caught sight of Sirzechs Lucifer who was kneeling and panting.

And that didn't surprise Gilgamesh, the power Sirzechs had gathered in that attack made a god-class being seem like nothing in comparison.

And although Sirzechs had absurd power, he was not used to unleashing so much power at once, it had been several centuries since Sirzechs had used so much power.

Gilgamesh just watched calmly as his [Rinnegan] deactivated.

If he wanted it would be simple to launch a second meteor, but Gilgamesh seeing Sirzechs condition thought that would not be necessary.

"That was pretty impressive Sirzechs, but now you have less than half your power, that won't be enough to beat me" Gilgamesh said calmly.

With his [Sharingan] the King of Heroes was able to measure the amount of power Sirzechs had, and after using so much even the Strongest Maou was worn out.

To the surprise of the King of Heroes, Sirzechs stood up as he let out a laugh.

"That's right, even if I had my maximum power I doubt I would be able to beat you in normal fashion" Sirzechs said slowly.

Slowly a crimson aura began to cover Sirzechs body.

Gilgamesh's eyes narrowed, the quality and quantity of the power was something totally different from what Sirzechs had released before.

The crimson aura began to expand from his body and the armor covering Sirzechs' body was suddenly annihilated by the power of his aura.

Obviously this was no ordinary armor, it had been specially created so that it could contain Sirzechs' aura, and yet it was destroyed so easily that it surprised Gilgamesh.

"To beat you I will have to give something in return" Sirzechs said calmly.

Over Sirzechs body a huge magic circle appeared, and thanks to his experience Gilgamesh recognized what it was.

"A magical sealing circle?" thought Gilgamesh aloud.

Before Gilgamesh's eyes the magic circle broke, causing Gilgamesh to widen his eyes at what he felt.

An overwhelming presence washed over the entire place, an amount of power so overwhelming that it distorted gravity itself, the pressure of gravity increased by hundreds of times over Gilgamesh causing the King of Heroes' eyes to widen with the pressure, although it didn't bother him much.

The nature of the energy was identical to what Sirzechs exhibited, but it was infinitely greater, like a chasm of difference, exuding so much pressure that it caused the battlefield itself to be affected.

It was as if a black hole had suddenly appeared on the battlefield, the surrounding gravitational field had become so tense that space-time itself was cracking, the surrounding trees were crushed and transformed into mere sticks due to the sheer presence of such magical power.

Even in the face of this all Gilgamesh did was to widen his eyes minimally at what was happening.

"Gilgamesh..." the voice of Regulus was present, showing concern.

"Yes, his aura is five times bigger than before, maybe more..." pondered Gilgamesh calmly.

However an immense smile appeared on his face when Gilgamesh realized what Sirzechs had actually done.

"So you went so far as to sacrifice your life to defeat Sirzechs!" cried Gilgamesh excitedly.

As the uncontrolled aura calmed down it was possible to see Sirzechs in the midst of that huge maelstrom of power, his hair floating as his eyes glowed crimson.

"So you figured it out? I guess you'd expect" Sirzechs said as his power increased.

What Gilgamesh had realized was something simple, Sirzechs had been storing up [Demon Power] since they had met for a future battle.

But doing this was not so simple, to obtain such massive power Sirzechs had turned his own life force into power and was storing it.

But to obtain such massive power Sirzechs had to sacrifice an absurd amount of his life force.

"Even for a Demon who can live almost eternally I have lost a lot of years, centuries or even millennia, honestly if I manage to live for the next five hundred years it will be a lot" Sirzechs said in a calm tone.

Faced with this, Gilgamesh was only able to laugh with animation.

"Hahahaha, impressive Sirzechs, would you go that far to beat me?! To kill me?!" shouted Gilgamesh excitedly.

Sirzechs' uncontrolled aura began to gather around his body as he absorbed all the energy.

Seeing this, Gilgamesh increased his power even more, his [Susanoo] that was only bones began to gain muscles and then skin, until he received an armor.

Seeing this, Sirzechs took a deep breath and pulled the power within him, just waiting to break free.

The world itself shuddered and then seemed to scream in terror as Sirzechs' aura grew larger and larger.

In an instant Sirzechs was engulfed in a cocoon of deep crimson, sending shockwaves of raw power reverberating not only across the battlefield, but across the entire barrier territory, and perhaps even beyond.

It would not be surprising if even humans, usually oblivious to the happenings of the supernatural world, were able to feel them with full force.

An entire ocean seemed to have appeared above Gilgamesh along with the entire battlefield.

A loud pop caught his attention, and he looked again into the eye of this storm of pure power.

The cocoon began to open, with red light coming out of the opening, filling the forest with an indescribable otherworldly energy.

Then, with the resounding sound of breaking glass and a blinding flash of red light, the cocoon was ripped open, sending a massive shockwave crashing through forests and destroying mountains merely by its presence.

In the space Sirzechs and the cocoon he was wrapped in, something appeared.
