Gilgamesh in DxD

It was Gram the strongest Demon Sword, also known as the Demon Emperor's Sword. A weapon with destructive power comparable to Durandal and with Dragon Slayer power comparable to Ascalon.

The second one was a long sword with a dark purple color that reaches halfway up the blade approaching the top where it is silver, it has a unique crossguard, a light purple part placed on the crossguard extending to the purple full with a small yellow circle in the middle making it look almost like an eye, a yellow handle with both hands and a purple hilt with light purple ornaments around it.

It was Balmung one of the Demon Swords with a drill-like aura that is capable of creating powerful swirls.

The third one has a much lighter color and ornate appearance that is different from other Demon Swords, it looks almost like a broadsword with a much wider blade, a blue crossguard that extends to the dark blue color fill with a light blue diamond in the middle with a hardening line that appears to be wavy on both sides, a gold handle and a uniquely shaped hilt.

It was Nothung one of the Demon Swords,specializing in sharpness with a power to cut through anything with great piercing ability.

The fourth is a long double-edged sword all black from the handle to the blade with four green diamond-shaped patterns in the center and a bat-wing-shaped crossguard.

Era Tyrfing is one of the Demon Swords, specializing in destruction, similar to Excalibur's Destruction. It has the power to release a pure destructive power that destroys everything it hits.

The fifth appears to be the most demonic looking sword which has a dark purple color, the handle that appears to be similar to a demon's wings on the right side, a horn shaped addition pointing down, a jagged black blade that has three diamond shaped jewels embedded within the blade near its base, three protrusions along the edge, a part of the blade pointing up in front of the three protrusions and a curved tip.

It was Dáinsleif a demonic sword capable of manipulating ice.

The last one was a sword of light to be used against Demons.

"Balance Breaker: Chaos Edge Asura Ravage" shouted Siegfried as he announced its power.

Siegfried's Balance Breaker created four silver draconic arms and for each arm its power was doubled.

Siegfried quickly advanced against Gilgamesh with his demonic swords in hand and Gilgamesh summoned a blade.

This blade is a double-edged sword that is about the length of an arm, with a small silver hilt and a small plumage of light yellow feathers around it, with leather wraps around the handle and runes on it. When activated, the blade glows with a bright light that can strike ordinary demons.

It was Claiomh Solais the Sword of Vituous Light, a Rank C Noble Phantasm.

A blade that usually appears in Irish stories and folklore that talk about a hero forced to complete three tasks to be proven worthy of his abilities, it belonged to Nuada Airgetlam, who was the first king of Tuatha De Danann, and considered one of the four treasures of the country. Because it is more of a ceremonial weapon that deals with storytelling, its purpose as a weapon of war is severely diminished, becoming little more than a glorified dagger.

However when wielded by someone who has mastered the art of the sword like Gilgamesh its power can easily match other Noble Phantasms, having its power increased by Gilgamesh's divine power and fortified by Gilgamesh's [Busoushoku Haki].

Gilgamesh quickly imbued his divine power into his sword as he advanced against Siegfried.

Both began exchanging blows at unusual speeds, both seemed like mere blurs before they met and collided.

Siegfried was much stronger than in the cannon due to all the training he had with Gilgamesh.

However regardless of which blow Siegfried used Gilgamesh would respond with the opposite technique and nullify it.

Quickly with mastery and mastery that transcends mortal abilities Gilgamesh overpowered Siegfried.

Regardless of what Siegfried did Gilgamesh would strike back.

Siegfried would release waves of destructive energy from Gram with the cutting power of Nothung, but Gilgamesh would strike back by releasing waves of his divine power.

If Siegfried used Dáinsleif to release waves of ice Gilgamesh would respond by creating and releasing torrents of high-level flames.

In one such slip-up Gilgamesh made Siegfried fall to the ground unarmed before pressing his sword into his neck.

Gilgamesh's sword was leaning against Siegfried's neck causing a trickle of blood to flow.

"What's the matter? Aren't you going to kill me? You have become so weak" Siegfried said angrily.

Gilgamesh narrowed his eyes.

"Don't confuse piety with weakness" said Gilgamesh seriously.

"I will not" said a voice.

Gilgamesh's eyes widened before he jumped away just in time to avoid a blow from Cao Cao with his spear.

"Nice reaction" said Cao Cao smiling as Siegfried stood up.

"So you let your subordinates fight so you can attack the distracted enemy? What a great hero" said Gilgamesh sarcastically.

Cao Cao simply smiled.

"Well they wanted to fight you, who am I to stop them" said Cao Cao before getting into combat position.

"But I guess it's my turn now" said Cao Cao smiling.

Gilgamesh dispersed his sword before another weapon manifested in his hands.

Manifesting through a small golden light appeared a spear in Gilgamesh's hand.

It was a large spear, about two meters long. It had an intense crimson red color similar to blood. The lower part of the blade was serrated with a sharp point, and the handle had indentations similar to blood veins that extended to the end of the handle.

The spear emanated a bloodlust that even a non-combatant would be able to feel.

It was the cursed spear of the Celts, a descendant of the Norse spear Gungnir, and Brionac, the spear of the Celtic Sun God, father of its best known bearer, Cu Chulainn. The tragedy of this weapon is one of the most infamous of all demonic weapons in the world, but despite its infamy, few have seen the weapon, for it is jealously guarded by the Celtic Sun God, Lugh. Those few who have seen it all report the same thing, however, a blood-red spear with an overwhelming amount of bloodlust emanating from the weapon.

It was Gae Bolg the cursed Celtic spear.

Originally obtained by the immortal witch Scáthach through means lost in time, she finally gave the weapon to one of her most successful students, Cu Chulainn. The witch then asked her student to kill her, but with sadness; she had become so powerful that she had been cursed to 'not be considered human'. Not even the cursed spear could end her existence, so Gae Bolg failed to kill the one person she was supposed to kill.

Eventually, Cu Chulainn left, taking Gae Bolg with him and forged his own legend as the 'Shield of Ulster', but in the process ended the life of his close friend and son with the cursed spear. It is known for its ability to 'reverse the nature of causality' ensuring that the opponent's heart is pierced, a weapon that will never stop killing as it always strikes the organ vital to the body.

Fighting this weapon was like signing your death warrant, for the moment her name was invoked only death would remain for the opponent.

"Hohoho, what a beautiful spear, I can only imagine a spear that can exude such bloodlust, so that's Gae Bolg, huh" spoke Cao Cao as if not bothered by the Celtic spear.

"Very well let's see which is more powerful, my sacred spear or your demonic spear" said Cao Cao as he prepared himself.
