Gilgamesh in DxD

Tiamat was running out of options, naturally she should have the advantage due to her brute strength and size due to being a dragon, but that wasn't happening.

Gilgamesh had managed to nullify any blow that she gave with her strength and her wind magic thanks to Focalor, this djinn was especially good at nullifying the powers of his enemies due to the most diverse ways of manipulating the wind.

Tiamat widened her draconic aura before assembling it into a single point and firing it like a large condensed aura projectile. Gilgamesh quickly brought his hands together and formed a projectile of concentrated air and launched it at Tiamat's.

Both collided generating large shock waves that traveled throughout the forest.

Gilgamesh looked at Tiamat with a smile.

"Is that all you have? Because I killed flies that gave me more trouble than you did" Gilgamesh said to the already irritated Dragoness.

Tiamat soared higher in the sky before fully extending her wings as she began to let out a deafening roar. The wind started to get stronger as her aura began to expand, while a dark blue almost purple ray began to dance around her body getting more chaotic by the second. Gilgamesh looked at Tiamat with an awed expression on his face.

"That's really impressive," said Gilgamesh aloud.

He really wouldn't get away with it, although he was immune to lightning he wasn't immune to shock waves.

"I'll show you what happens to those who annoy the Dragon of Chaos and Karma!" Tiamat declared as she unleashed a huge powerful lightning arc from her mouth, which struck Gilgamesh at blinding speeds.

Gilgamesh quickly raised his hands creating two tornadoes a layer of tightly compressed and compressed wind formed around his arms.

"Foraz Zora" said Gilgamesh as he summoned his technique and launched against Tiamat's.

A massive explosion sent dust and debris flying everywhere as Tiamat landed on the ground with a satisfied expression on her face.

"That was for You to see what happens to someone who annoys me," said Tiamat pleased but with mild annoyance.

"That wasn't so bad, if I hadn't defended myself in time you would have caught me." Gilgamesh's voice came from the smoking crater as Tiamat's eyes widened in surprise and a little joy. Gilgamesh leapt from the smoking crater and stopped in midair above Tiamat as he smiled.

"How are you still alive?" Tiamat asked.

Gilgamesh smiled.

"It was a wonderful warm-up, Tiamat. Now it's time to get serious, don't you agree?" Gilgamesh said with a smile as Tiamat's eyes widened in horror at what she'd just heard.

"You call it heating!? What kind of monster are you!?" Tiamat screamed, obviously not believing what she had just heard.

Gilgamesh smiled as he raised his two arms causing two large tornadoes to appear that grew and rose to the sky and encompassed his hands and he joined them above his head causing the tornadoes to mix causing Tiamat to widen her eyes when she saw an attack five times stronger than the previous one.

Tiamat quickly prepared to release her flames but it was too late.

"Foraz Zora" screams Gilgamesh as he launches the two tornadoes combined together against Tiamat who fell like a gigantic grief against Tiamat who was crushed by the pressure of the tornadoes against her.

Gilgamesh posed beside Tiamat's crater and as the dust cleared he saw Tiamat crushed to the ground with several cuts and bruises and bruised scales.

"Then?" asks Gilgamesh as he crosses his arms.

"I...give up...become your familiar," said Tiamat weakly.

Gilgamesh smiled before undoing his transformation and going to heal Tiamat.

With Rias.

The sound of footsteps can be heard walking towards the group. Rias turned around ready to lend her help to Gilgamesh after the battle only for his words to die in his throat. Standing in front of her and her peerage and Satooji was a shirtless Gilgamesh and a beautiful woman, she has the appearance of a beautiful woman with long straight hair, light blue, dark blue eyes and a cool atmosphere that radiates from her beauty. She has an extremely powerful dragon aura within her body. She also wears a navy blue skirt, and her entire body is drenched in a deep blue color.

It was Tiamat in her human form.

"Tiamat-sama!" Satooji bowed to the strongest of the Five Dragon Kings.

"Ah. Satooji-san, it's a pleasure to see you again. I thought you would be the home teacher now?" Tiamat asked tilting her head to the side as the man in front of her shook his head.

"No, but my final test is coming up. And I hope to pass." Satooji said proudly as Tiamat nodded giving the man a small smile.

Both Akeno and Rias were looking good, really looking at Tiamat.

"I suggest you two don't look at my familiar like that." Gilgamesh said as he crossed his arms over his chest and displayed a fraction of his murderous intent. Tiamat had to admit that Gilgamesh was a very handsome and wonderful man, even by supernatural standards.

"He really is a monster, there is a limit to his power" thought Rias terrified as she shivered a little.

Kiba didn't know if he should feel impressed or afraid of Gilgamesh at this point. The fact that he was able to make Tiamat familiar with him just showed how powerful he really was.

"For him to bring down a Dragon who is said to possess the power of the Satan Class... I'm speechless, I just hope he remains an ally and doesn't become an enemy" Yuuto shuddered at the thought of Gilgamesh being an enemy.

Satooji could only look at Gilgamesh with nothing but respect.

"You surprised me young man. I honestly thought you were going to die today, but you proved me wrong. And you have the most powerful and most beautiful being in this forest, as you are familiar. I hope you take good care of it." familiar said before giving Gilgamesh a slight bow.

Gilgamesh nodded as he opened a golden portal and pulled out a T-shirt and donned it to the disgust of Akeno and Tiamat who were looking on.

"So where are my friends?" Gilgamesh asked the others.

"I'm here Gilgamesh," said a voice behind them.

Gilgamesh turned and looked back and saw Arturia coming towards him with Regulus in her arms and beside her there was a gigantic lion three meters tall.

"So this is your familiar Arturia?" asks Gilgamesh.

"Exactly. This is Artus" said Arturia waving at Leo who let out a roar that scared the devils.

"How amazing! A Nemean lion" said the master of family members smiling and his eyes shining.

Everyone turned their doubtful gaze to him who coughed a little until he started to explain himself.

"The Lion of Nemea are the descendants of the Lion King of Nemea who fought Hercules in Greek myth, they are extremely rare and powerful, they are able to fight High class Devils and win, they also have extremely tough skin, although not at the level of their ancestor, they are also rare as they don't kneel down to anyone and only choose the most honorable and fair people to be their masters," explains Satooji to everyone.

Everyone nodded, while the Fiends were amazed that a familiar was able to fight and win against High-class Fiends.

Meanwhile Gilgamesh was surprised that there were descendants of Regulus.
