Gilgamesh in DxD

In an instant, Sebas disappeared and came up in front of one of the members and struck his head so hard it blew it up.

Raising his blade-shaped hand, Sebas lowered it and in that instant all the other members of the Heroes Faction were beheaded.

Such was the power of the man who trained and taught Gilgamesh all these years.

Sebas looked around and saw that it was full of bodies and blood everywhere.

He raised his right hand and made it appear a sphere of purple energy created from [Magic of Destruction] and threw it over the bodies.

The energy began to annihilate everything ahead and wiped everything out of existence, whether the bodies or the shed itself.

Sebas sighed before withdrawing and heading home.

The next day all the locals would wonder what happened to the shed that had literally disappeared from existence.

Another day.

Academy Kuoh.

Currently within the corridors of Academy Kuoh most students were leaving to go home, as the time had passed.

But even though it was closing time it was still possible to see some students walking through the corridors.

Among them was Gilgamesh who walked the halls drawing attention wherever he went with everyone looking at him.

Gilgamesh was heading towards the Occult Research Club Room at Rias's request.

The Kuoh Academy's Occult Research Club was originally abolished due to lack of members. Upon entering high school, Rias and Akeno revived the club as president and vice president, eventually making it the base for Rias and her servants.

The club itself serves as servants to front Rias, and other supernatural individuals who appear later in the series, in order to get out of school activities or classes in an emergency, such as having to hunt down a Lost Devil or to destroy a fallen angel

The abandoned dormitory was secured with school funds and is used as a base that prevents scrutiny from other students.

The club house is a three-story building, with the third floor serving as a clock tower. It was painted white with a black roof with vines climbing up to the second floor.

Gilgamesh quickly reached the club door and knocked on the door twice until he heard an 'enter' then he turned the knob to enter.

The interior of the club room is a wood-paneled room with Victorian-style sofas and chairs along the walls. One side is set up to be used as a bath, and a large Gremory Family magic circle is also there to allow teleportation to and from customers.

Gilgamesh entered the room and saw Rias sitting at her table with Akeno beside her making tea.

Koneko was sitting on a sofa while eating a candy bar and Kiba was sitting beside her while polishing his sword.

The biggest difference was the addition of Issei Hyoudou who was sitting on another sofa while leering at Rias' swaying breasts.

Gilgamesh stood with his arms crossed.

"So what did you want Gremory-san?" asks Gilgamesh seriously.

Rias turned her gaze to Gilgamesh and smiled nervously.

"Hey Gilgamesh-san" says Rias smiling nervously.

She still remembered the power that Gilgamesh wielded and that still scared her.

When she met him she thought he wouldn't attack her because that would be like picking a fight with Clan Gremory, one of the 72 pillars of the Underworld, and Sirzechs Lucifer one of the Four Maou.

However, she admits that she felt guilty when she manipulated him, even more so with the conversation she had with her parents.

Her conversation with her parents was horrible, she had never been so outraged by her family and her parents even wanted to withdraw her territory from her, but thanks to her brother she still managed to keep it.

When she found out that her brother had gone to talk to Gilgamesh she thought everything would be fine, but when her brother arrived and gave a big warning not to antagonize Gilgamesh.

This has already made clear the position and power of Gilgamesh.

But a voice cut everyone's mind.

"Buuuuchooouuu what is this cute boy doing here?" shouts Issei indignantly.

It was no secret that Issei didn't like Gilgamesh, either because he was a pretty boy, or because Gilgamesh always stopped Issei from spying on girls and usually ended up with Issei getting beaten up by Mordred.

"Issei this is-"

"Buchou don't tell me he's part of your nobility" shouts Issei.

"Ara ara Issei maybe you should be quiet and let Buchou explain" said Akeno sweetly causing a shiver to run down Issei's back.

It was no secret that Akeno had a crush on Gilgamesh, whether it was the power of the descendant of the King of Heroes or the fact that they had gotten along so well on their first meeting.

Gilgamesh really liked Akeno, although her nature as a Fallen Angel exudes a rather sinister aura, the King of Heroes liked Akeno as a good friend, they had talked a few times.

"This is Gilgamesh the descendant of the King of Heroes and the current Longinus user [Boosted Gear] being the Sekiryuutei" said Rias in a tone of explanation.

Issei's eyes widen in surprise.

"Longinus? Isn't that one of the Sacred Gear capable of killing Gods?! Never mind I can beat him easily with my Sacred Gear" yells Issei as he summons his [Twice Critical].

His Sacred Gear [Twice Critical] forms in the appearance of a small green gauntlet in his right hand.

For Issei he could beat Gilgamesh without problems, after all from what Rias had told him that the Devils are several times stronger than a normal human and that's why he could win without problems.

All the devils in the room were staring at the whole thing scared because they really didn't want to have the same situation as when they threatened Gilgamesh last time.

Gilgamesh looks at all this curiously.

As far as he knew Gilgamesh had given three Sacred Gears to Issei to [Flame Share], [Twice Critical] and [Night Reflection].

But from what it looked like Issei had only awakened one of the three Sacred Gear he had been given, it appears that Issei hadn't been able to tap into the power of the other Sacred Gear, from what it looked like Issei was only able to wake up the [Twice Critical], and this does not surprise Gilgamesh.

After all, Issei no cannon wasn't able to wake up the [Boosted Gear] but only her in the form of [Twice Critical], so Gilgamesh is not surprised it's likely that Rias didn't even give Issei proper training when he saw his Sacred Gear.

Gilgamesh looked at Issei with a look that made him freeze.

"Look here Issei, I am a descendant of the King of Heroes who was a demigod son of the Sumerian Goddess of Love, so I can draw on some of the powers of this domain" says Gilgamesh to Issei.

"What do you mean" yells Issei uncomprehending making Gilgamesh sigh.

"Let me explain it in a way your underdeveloped mind can understand. I am able to manipulate these domains and for that I can curse you so that no one else loves you or lusts after you" said Gilgamesh making everyone's eyes widen.

"Y-y-you wouldn't do that," said Issei, stuttering in fear.

"I'll do better," said Gilgamesh as he pointed his finger at Issei and caused a bolt of lightning to appear and hit his head.

Issei and everyone was scared while Issei tried to see if he had any injuries.

"What did you do?" screams/asks Rias only to be ignored by Gilgamesh.

Leave some power stones for this novel, maybe I'll throw a bonus chapter if we get a decent amount.
