Gilgamesh in DxD

Especially God is dead now and the System also shows signs of changing recently.

And the divine power that Gilgamesh released was no small thing, it was easily greater than that of the Seraphim who were present in the room, and they are creatures made by God directly.

All the leaders and beings in the room, with the exception of Gilgamesh's group, became tense.

Their instincts were screaming and begging them to kneel before Gilgamesh, that this would be the only way for their lives to be spared.

Sirzechs and Azazel were already sweating as they remembered this feeling.

The same feeling they had felt when they first confronted Gilgamesh.

Fear.

Even the power of Sirzechs who is a Super Devil seemed like a mere candle flame when compared to the immense fire that was Gilgamesh's power.

Gilgamesh only smiled as his power manifested.

'CHING!'

Without warning, silver chains appeared from golden portals and wrapped the different leaders, Grayfia and Vali in their chairs, leaving them very little room to move, the only one who was not trapped was Gabriel.

"What?" The leaders look shocked at the speed of the movement and Grayfia started trying to move her way out only for the chains to get tighter. Vali, on the other hand, was examining the chains with a curious look.

"Gilgamesh what are you doing?" asked Michael as he kept his cool.

"Azazel wanted an example, so I am illustrating." Gilgamesh gave that answer before turning to the others, who in turn were quite calm except Grayfia who looked about to burn her face, "I suppose you have heard about the punishment of Prometheus?"

"The titan Prometheus who set humanity on fire in Greek mythology?" Michael asked as he leaned back, no longer trying to resist his confinement, "He was turned into a human and chained to the Caucasus for the eagle to consume his entrails, but he would continue to rise again until midnight. A very cruel punishment done by Zeus at that time."

"That is true, but in this case." Gilgamesh held up the chain that wrapped around his arm, "This is the chain that was used in the punishment. This is [Chains of Prometheus], an item used to bind the immortal Titan to his destiny."

"These are the actual chains?!" Azazel looked down around his body, his initial discomfort now forgotten and replaced by scholarly curiosity at the prospect of examining the chains.

Gilgamesh was lifting the chains slightly, the illumination revealing runes along the links of the chains.

"These chains were made from the metal used for Prometheus' prison and their powers are reinforced by legends and stories. Obviously they are the originals."

"Interesting ..." Azazel looked at the chains very closely, his eyes dancing around the links to study the runes.

"That is interesting, but I doubt that is all you have if you wish to reinforce our promises." Sirzechs spoke as he looked at Gilgamesh cautiously.

A golden portal appeared next to Gilgamesh and from it a sword appeared.

It was a straight double-edged sword that was jagged along the length of the blade, its handle simply adorned with a single embedded green gem and a small hole in the tip.

"This is the [Sword of Shannara], also called the Blade of Truth." Gilgamesh gestured to the blade in question, "Superficially, it does what it is supposed to do, make the user and the intended target tell the absolute truth. However, it has an additional side effect in the form of oaths. By itself, not much." He pulled lightly on the chains as he moved the sword to secure it by the handle, "But if accompanied with [Chains of Prometheus] it actually enhances the power of this side effect, which means ..." Gilgamesh paused for a moment before continuing.

"I just need to attach the chains to the target in question and make them swear an oath that needs to be fulfilled, with the punishment varying from any type, the highest penalty being instant death."

'WHAT?!' Everyone's thoughts came to a halt at the words that came out of his mouth, further evidenced by the expressions on everyone's faces except the leaders who looked at him with an intense stare, and Vali who had a disturbing expression.

"That's a pretty bold statement." Azazel commented as he continued his smile and steady gaze, while the feeling of pressure increased around him, "Would you like to give a demonstration?"

Gilgamesh's mischievous smile only widened even more leaving even his friends apprehensive.

"All right then." Holding the handle so that the blade pointed at the ground, Gilgamesh turned to the Fallen Angel and looked him in the eye.

"The witnesses are as declared: Sirzechs Lucifer and Serafall Leviathan of the Devil Faction, Michael and Gabriel of the Heaven Faction, The Hakuryuukou, the heiresses of the Gremory and Sitri Clans. The oath to be kept: Truth about the recent thefts and attack with the Excalibur shards. If you do not tell the truth, the person in question will suffer damage according to the lies that are told. This oath is active from this moment on" Gilgamesh said without bothering to mention his friends, after all they were not bound by the chain.

"How about a little test?" Gilgamesh looked Azazel in the eye, "Tell me, did you know he was going to steal the shards of Excalibur?"

Azazel looked down at his own body as he flexed his fingers, frowning slightly as if feeling the chains before turning to Gilgamesh.

"No"

"But did you suspect he might do something?" Gilgamesh held his gaze as he continued with his questioning.

"...Yes." The Fallen Angel replied now looking less uncomfortable.

"So you tried to contact someone about this?"

"I did." Azazel shrugged his shoulders.

'SPLAT!

Everyone turned to look at the blood that suddenly appeared on the floor. Upon closer examination, the blood originated from a deep cut that appeared on his arm. Sona and Rias felt a tightness in their stomach at the sight of the veins and muscles.

"You may want to answer truthfully, Azazel. Depending on your lies, the severity would increase." Gilgamesh said without seeming the least bit surprised by what had happened, "You didn't try to warn them, did you?"

"No, I didn't." Azazel spoke the truth this time as his wound began to heal, leaving behind entire skin and a small tattoo of a chain link. Suddenly, the atmosphere in the room seemed to have changed with everyone now understanding that Gilgamesh had called his bluff and was now demonstrating it.

"Do you know the person who was acting as Valper's informant?" Gilgamesh asked with his eyes changing color momentarily.

"Yes." Azazel replied now sporting a very serious expression.

"Then can you tell me details about him?"

"Sorry, he's dead ~ AHG!" Azazel spoke only to scream in pain when a larger cut appeared on his other arm, before closing up again with a larger tattoo in its place.

"Azazel!" cried Vali surprised and a little worried.

"Do you doubt my words now?" Gilgamesh spoke to everyone as he held up his sword.

"This is a mere sample of what I can do to enforce my oaths on anyone who tries to hurt innocent people in this area or anywhere else. If I see a normal or innocent person being attacked by anyone from your factions, whether they are from your organizations or outside factions, I will do whatever it takes to make it clear that no one under my supervision will be hurt" His eyes hardened as he looked at the leaders. "Are we clear on that?"

Everyone felt pressured by Gilgamesh's presence, the presence of someone blessed by the gods who lived a luxurious life.
