Gilgamesh in DxD

In physical combat she is better than Sona, but she is worse in magical combat.

Well, she was always struggling physically.

System, what is her Sacred Gear?

[Mirror Alice: The user creates a mirror that has the ability to reflect attacks with double damage to the attacker, but it cannot be summoned twice in a row without a cooldown period, however, it can evolve to a level at which the user can create multiple mirrors at the same time]

I see, basically a Sacred Gear version of Meliodas's Full Counter.

Sona is standing in front of Gilgamesh pointed to a chessboard there.

"Play?" she asks.

"Let's go," says Gilgamesh, looking at the board.

"So Gilgamesh if you don't mind asking me, why did you go back to school? As far as I knew, you attended school at home and had excellent grades, plus I heard you have two college degrees," Sona said with genuine curiosity.

"Well, I was really interested in what school was like, and besides, my mom went to school here," Gilgamesh said, not surprised that Sona knew about him.

Due to his parents' fame he was also very famous.

Sona nods.

"I see, given who your parents are. It's so nice to have someone like you here, Mr. Gilgamesh, even though your name is…" Sona said as she stopped to think.

"Exotic," said Gilgamesh as he moved a piece on the board.

"Exactly."

"Well, my parents like exotic names, I think you know the Epic of Gilgamesh," says Gil as he looks at Sona.

"Yes, a good story I must say, I just hope you and your friend doesn't cause trouble," Sona says as Gilgamesh nodded.

As the game progresses, it looks like Sona will have another victory. "Well, Mr. Gilgamesh, this is checkma-." Sona didn't finish that statement, as she didn't notice Gilgamesh had led her into a trap.

"The art of war Shitori-san, one of the simplest tactics, look weak in front of your opponent to make them let their guard down," Gilgamesh said with a smile.

Gilgamesh then performed a set of moves that eventually overthrew her king.

"I believe this is checkmate." Sona was completely shocked at having lost for the first time.

"You deliberately made bad moves in the game so I could let my guard down and you could take my king, and you only did it on your first try!"

"That's correct," Gilgamesh said with a stoic expression.

"Who exactly are you?" Sona said as she looked at him with shocked eyes.

"I am nobody special, I'm just Gilgamesh." Gil said calmly. Sona just searched his face, seeing that he was really telling the truth. "If you're so intent on examining my face, you should have brought a camera beforehand."

Sona blushed at the comment and then looked back at the chessboard.

"He is the only man who beat me in a game of chess, I even rejected my ex-fiancé for not being able to beat me." Sona looked once more at Gilgamesh and felt her heart race.

"Well I guess it's time for me to go," says Gilgamesh as he gets up and takes his schedule and leaves the room giving Sona a wave.

Sighing, a little Sona leans back in her chair.

That man in front of her was anything but normal.

When she learned that a student was going to enroll in her school and had the name Gilgamesh, she became alert.

After all, this name is very well known in the supernatural world.

Even more than a few years ago a descendant of him was confirmed alive who had still fought and defeated Sairaorg, and on top of that he had a Longinus Sacred Gear.

Of course, Sona kept her guard up when she learned that someone with that name was going to enroll in her school, but she didn't think it would be the same person.

After all, what would someone like that come to do here?

But the moment she saw him she knew he wasn't normal.

The way he talked, looked at her, hell, even the way he walked made her feel small. The majesty that emanated from him felt like a natural part of his very being.

When she saw him every cell in her body was screaming to kneel before him and swear undying loyalty.

Sighing, Sona couldn't help but think of getting him into her Peerage, but she doubted she would ever reincarnate him.

She just hoped her friend Rias wouldn't try anything silly with him.

She knew about her friend's problem and so let her stay with Issei Hyoudou who had a strong dragon aura, probably possessing the Sacred Gear [Boosted Gear] or [Divine Dividing].

Sona sure as hell didn't want to imagine what would happen if Rias tried to manipulate him like she is doing with Issei.

An angry descendant of the King of Heroes who still had a Longinus was definitely something she didn't want.

But deep down, Sona wished she were wrong and this man was just a normal human.

"I just want to have a normal day," Sona says with a sad sigh.

— With Gilgamesh —

Gilgamesh continued passing through the corridors, he would study in class 3-B, while Mordred was in class 3-A so they both split up to go to their respective classrooms.

Gilgamesh walked into the classroom and sat down, ignoring the lustful gazes of all the girls in class.

Gilgamesh closed his eyes and was silent as all the girls watched him.

His concentration was broken by a scream.

"KYAAAA"

Turning to the door Gilgamesh saw two girls enter through it.

The first was a beautiful young woman with white skin, blue eyes (blue-green in the anime, season 1-3) inherited from her father, Zeoticus, and a devious figure. Her body measurements are [B99-W58-H90 cm] [B39-W23-H35 in]. Her body weight is [58 kg] [128 lbs]. Her most striking feature is the long, beautiful red hair she also inherited from her father, which reaches to her thighs with a single strand of hair (known in Japan as ahoge) sticking out of the top. Her hair also has loose bangs covering her forehead and side bangs framing her face.

Gilgamesh recognized her.

Rias Gremory, the sister of Sirzechs Lucifer and the current heir to House Gremory, one of the 72 Pillars of the Underworld.

She is the heiress of Clan Gremory after her older brother Sirzechs gained the title of Lucifer. She is the only daughter and youngest son of Zeoticus and Venelana Gremory, aunt of Millicas Gremory and cousin of Sairaorg and Magdaran Bael. She is known as the Princess of Ruins of Crimson Hair.

The house that produced the current "Lucifer", members of Clan Gremory are characterized by their auburn hair color and their powerful demonic powers. The devils born from Clan Gremory are beings with extraordinary affection among their fellow devils. As such, they do not discriminate against their servants. Clan Gremory has a territory that is roughly the same area as Honshu, Japan, and also has a large number of castles for its relatives. As a very rich territory, it also has a developed industry.
