Gilgamesh in DxD

Riser had totally lost his train of thought, he was letting his anger blind him and attacking everything, he had taken all of his power that was focused on his regeneration and now had focused it totally on his attack power.

Gilgamesh looked slightly impressed before turning to Ravel who was cowering.

"Don't stand in front of me Ravel for if you don't you might get hurt" Gilgamesh said to the girl who nodded.

Gilgamesh stepped forward and looked at Riser before starting.

In an instant his mark from the [Ice Devil Slayer Magic] appeared on his arm, not that anyone could see because his clothes covered it.

Gilgamesh let out his breath which came out in the form of steam due to the sudden drop in temperature.

"Mana Zone..." whispered Gilgamesh as he used his technique to gain control of all the magical power within the [Rating Game] barrier.

The power of his Longinus [Zenith Tempest] skyrocketed as Gilgamesh pulled all the power he could access with the exception of his Balance Breaker.

Only one sentence was heard before the world froze.

"Absolute Zero"

*With Sirzechs and the spectators.*

All the spectators were watching anxiously to see what technique Gilgamesh would use after his sudden increase in power.

But just as Gilgamesh was about to use his power a wave of snow and ice swept over everything preventing them from seeing through the cameras of the [Rating Game].

Ajuka quickly got in front of his system and was trying to see if he could fix the problem so they could see or know what happened.

But the popping sound caught everyone's attention, looking at where the noise was coming from they saw that ice was starting to create itself on the structures of the hall.

Before they could do anything, the whole room was shaken, causing almost everyone to fly out.

Sirzechs together with Serafall and Ajuka quickly made their way to where the guests were and saw that ice was forming around the hall and quickly used their devil power to create a barrier to protect them.

"Lord Lucifer look at this" said a random devil as he approached.

He opened a portal and showing an image of the underworld.

Much of the underworld was suffering from strange weather events.

The underworld was large, the size of the earth without the sea, yet everything in a radius the size of a country like Japan was immersed in major weather disasters.

Hurricanes were falling on the land, unprecedented snowfall, heavy hailstorms.

"Climate manipulation? Who could be doing that?" Sona was always quick on the uptake said as she approached next to Rias.

"That's the same magic power as Gilgamesh" Ajuka concluded making everyone's eyes widen.

"Impossible for a single person on this scale, even a Satan cannot manipulate the weather from such a large radius of reach, not only that but be able to overcome the barrier of the [Rating Game] and affect much of the underworld. That has to be a multi-stage ritual." Sirzechs concludes.

"Normally you would be right, but there is a spell that can do that." said Enkidu as he approached them.

"I've never heard of a spell that could alter the weather like that" said Ajuka curiously.

"It's called Absolute Zero" said Enkidu to everyone.

"How does it work?" asked Serafall curious.

"Absolute Zero is the manipulation of heat energy at higher levels. Every amount of heat is negated. A center of absolute zero that causes even the flow of time to stop. An absolute protection of time. Any and all movement not authorized by Gil is forbidden. Ice magic is quite accelerated where even a novice level spell has the power of a master level. Master level spells are practically one-shot god-killers" explains Enkidu as he turned his attention to the screen connecting the battle.

"An army killing technique" said Serafall in surprise.

Everyone turned their attention back to the screen and couldn't widen their eyes at what they saw.

When the snow wave passed and it was possible to see what happened.

The whole battlefield was immense in a great amount of ice where there was no part of it that was not immersed in ice and snow, even the air was freezing and the strength of the ice was exceeding even the [Rating Game] barrier.

Everyone was absurdly surprised by this being especially Grayfia and Serafall.

Both were two masters in the use of ice magic, so much so that in the past their battle for the post of "Leviathan" had frozen much of the underworld.

Serafall even thought that this power of Gilgamesh was like her [Celsius Cross Trigger] technique that converts the earth itself into a frozen wonderland.

But she quickly dismissed that idea, this was much more than simply freezing.

Serafall was able to sense an oppressive amount of magical power concentrated in every piece of ice that Gilgamesh.

Then Serafall understood the real power of this magic, it was much more than simply creating a world of ice, to be able to freeze an entire city instantly and still be strong enough to overcome the barriers of the [Rating Game] and affect much of the underworld with weather disaster.

It was a feat that all users of ice magic sought for their entire lives, even Serafall had already tried to achieve this but failed, it was ice beyond ice.

It was a magic that recreated a frozen world with the power of absolute zero.

Absolute Zero is the full potential of an ice-based magician; it is said to be an "ice beyond ice" and the fruit of the labor for which every ice-based magician strives, enabled through the zenith of cold manipulation achieved by understanding the "essence of ice." Absolute Zero itself is recognized as being the lower limit of the thermodynamic temperature scale, a state in which the enthalpy and entropy of a cooled ideal gas reaches its minimum value.

Even Serafall with all her immense demonic power and extreme talent was not able to do it, none of her spells were able to reach this level, able to freeze any enemy? Yes, but not of reaching absolute zero.

In the case of every ice-based magician, a feat like lowering the temperature to induce any form of ice-derived magic might seem like a fairly simple operation, but to completely circumvent the Laws of Thermodynamics in order to induce Absolute Zero is impossible by supernatural beings, or that's what Serafall thought.

The closest thing to that was Longinus [Absolute Demise] who claimed to be able to achieve Absolute Zero, but no one has ever been able to do that.

So to be able to see someone perform this technique right in front of him was something beyond impressive, it was like seeing a dream come true.

It was so...

"Beautiful..." whispered Serafall as she saw the ice paradise created by Gilgamesh.
