Gilgamesh in DxD

Unbeknownst to Gilgamesh, the underworld had not seen this kind of attack since the days of the Civil War, and if Sirzechs detractors had seen what he had done, they would think twice before challenging him. Still, the King of Heroes seemed unconcerned as the spheres of Destruction approached.

"Some people never learn" He said shaking his head at the impending attack.

While nowhere near as fast as the previous attack had been, each sphere was packed with enough power to totally decimate a Supreme Class Demon and the number hurtling towards them would have even posed a danger to the Deities.

Opening his eyes Sirzechs could perceive a considerable change in both Gilgamesh's aura and power.

His blood-crimson eyes had been replaced by a vibrant red, three black tomes appeared around his black pupil.

And then they changed again.

The black tomes blended together as they rotated while taking on a new form.

It was the [Eternal Mangekyou Sharingan] of Gilgamesh.

To Sirzechs surprise what occurred next shocked him.

A thin tear trickled from Gilgamesh's right eye.

However, it was made of blood.

"Amaterasu"

At the command of Gilgamesh's voice, an immense blaze of infernal flames manifested to Sirzechs' surprise and crashed into the spheres of [Power of Destruction].

The black flames clashed and intercepted the [Power of Destruction], Sirzechs' power sought to destroy everything while Gilgamesh's flames tried to incinerate the Demon's power.

And this led to a stalemate in which both were being nullified.

Sirzechs' eyes widened as he saw that his [Power of Destruction] was being suppressed.

This was the power of [Amaterasu], one of the techniques of Gilgamesh's [Mangekyou Sharingan]. Said to be the highest level fire technique and the representation of the "Material World and Light," [Amaterasu] is the antipode of [Tsukuyomi].

A technique that consists of materializing black flames at the focus point of the user's vision. In ordinary situations it is almost impossible to avoid [Amaterasu], however, if the target can move fast enough to avoid being focused, it will be impossible to materialize the flames in the desired location. The black flames can continue burning for seven days and seven nights, and it is impossible to extinguish them with water or other normal methods unless the user extinguishes them according to his will. The black flames of [Amaterasu], said to be "the fire of hell" and also said to be as hot as the sun, burn any material (including other flames) until only its ashes remain.

What was once a physical battle between the strongest Maou and the strongest Hero turned into a battle of attrition, the first to tire would lose.

Sirzechs further increased the output of his [Demonic Power] and his [Power of Destruction] as dozens of crimson spheres manifested and advanced towards Gilgamesh while annihilating everything in their path.

Already Gilgamesh continued to release his [Amaterasu], moreover using another technique [Enton: Kagutsuchi] that possessed the power to shape black flames Gilgamesh had shaped his [Amaterasu] into dozens of black flame arrows and fired them at Sirzechs power.

The surrounding space was distorted by the clash of the power of both fighters, the very fabric of reality seemed about to shatter in the face of the sheer power of Hero and Maou.

However, the one who was tiring first was Gilgamesh.

Sirzechs had a huge [Demonic Power] as well as centuries of experience with the use of his power.

But for Gilgamesh it was more complicated.

Although he had mastered the use of the [Mangekyou Sharingan], it was rare that the King of Heroes resorted to the power of his eyes.

Because of his overwhelming power Gilgamesh only used his own power or that of his Sacred Gears, it was extremely rare occasions when Gilgamesh used his visual power.

And that's why using [Amaterasu] in such quantity was really tiring.

Besides the large amount of power that the [Mangekyou Sharingan] charged to stay active in addition to the cost of the [Amaterasu] itself, they still put enormous pressure on Gilgamesh's body.

Possessing the [Eternal Mangekyou Sharingan] only prevented Gilgamesh from going blind, but his body still suffered the damage from using the eye techniques.

Obviously if Gilgamesh used all his power, such as activating his [Rinnegan] or [Tenseigan] the victory would come quite easily.

With the [Black Path] of the [Rinnegan] Gilgamesh could absorb any Sirzechs attack among other ways.

But that was not what the King of Heroes wanted.

Gilgamesh was consciously limiting himself so that he could enjoy the battle more, he was limiting his power so that he could fight longer.

And this took its toll, because of the tension in his eyes due to the constant use of the [Mangekyou Sharingan] Gilgamesh was forced to close them for an instant.

And that was the opportunity Sirzechs needed.

Seeing the black flames diminishing, Sirzechs increased his [Power of Destruction] even more as dozens of crimson spheres were created and advanced at all possible speed against Gilgamesh.

When Gilgamesh opened his eyes the crimson spheres were already in front of him.

A huge explosion generated by the shock of the [Demonic Power] occurred generating a huge shockwave in the whole area.

Sirzechs watched calmly, he knew that this was not enough to defeat Gilgamesh, he also noticed that the King of Heroes seemed to be holding back.

However, when the cloud of smoke disappeared, what had emerged shocked Sirzechs.

An immense golden aura covered and protected Gilgamesh's body, it took the form of the upper part of a human skeleton with a long sword in one of its hands.

That was the [Susanoo], the third ability granted to those who awaken the [Mangekyou Sharingan] in both eyes.

The creature that covered Gilgamesh swung its sword releasing an immense shockwave that caused Sirzechs to be forced to jump away in order to deflect the attack.

Quickly Sirzechs waved his [Power of Destruction] spheres at the avatar protecting Gilgamesh.

However the moment they collided all that had occurred was an explosion, which when the cloud of dust disappeared the intact [Susanoo] was revealed to Sirzechs' surprise.

Gilgamesh's [Susanoo] was being fully coated with his [Divine Power] and therefore had a much higher resistance than normal.

"That was interesting for Sirzechs, but allow me to return the favor" Gilgamesh said with an immense smile.

To the surprise of the Crimson Maou the energy avatar protecting Gilgamesh dispensed his sword and his hands came together.

And in that instant the [Rinnegan] manifested in the left eye of the King of Heroes.

And then a single technique was announced by Gilgamesh.

"Tengai Shinsei"

After hearing Gilgamesh's words, the Crimson Demon King prepared for whatever Gilgamesh had prepared.

But after a moment Sirzechs stared in doubt when he saw that nothing had happened and even thought that the technique Gilgamesh had failed.

But he quickly dismissed this idea.

The entire area of the battlefield had been covered by an immense shadow, and as Sirzechs looked up he was surprised and frightened by what he had seen.

An immense meteorite, twice the size of the city of Kuoh was falling over the region.

Actually, falling would not be the best way to describe it, since the meteorite was only a few hundred meters above Sirzechs and Gilgamesh.

Sirzechs' surprised expression turned to Gilgamesh as [Susanoo] protected him.
