Chapter 1: Surfacing of the Red Dragon

"It's time Issei, time to show them the power of the Red Dragon emperor." A sexy feminine voice stated from the door of the ruined throne room that surrounded the man, who looked only 20 years of age, maybe a bit older.

"Ah, has it already been 100 years. Well we better make haste for I hear that the Gremory and Sitri heir are in Kouh, a small town in Japan." Issei stated, disgust in his voice upon mentioning the words Gremory and Sitri. Issei rose from the decayed throne he had been seated upon and moved towards the door where a blonde haired beauty awaited him. "Let's go reclaim my throne, Gilgamesh."

-100 years in the past-
The minute Issei crossed the border into his family's territory his senses screamed at him that something was wrong. The barrier that surrounded his family's land wasn't active and that only meant one thing, his family had been attacked. Issei enhanced his legs with his magic and moved at breakneck speed towards his family's house and the sight that greeted him when he burst through the door made him collapse to his knees and throw up his previous meal. In the lobby of his family home alone there was limbs of the servants and family members scattered everywhere and most of them Issei couldn't recognize.
"M-Master….Issei." A weakened voice called out from nearby and Issei rushed over to the voice to find his butler, Al, crawling along the ground towards him, his lower body missing.
"Who….Who did this?" Issei asked the butler kneeling down to grab his hand softly.

"The….new Satan….faction...they...they….." He began before his eyes rolled over and his body went cold and he became unmoving.
Issei's eyes flashed with anger, pure unadulterated anger as his body began to emanate a deep crimson light.
"Don't worry everyone…. I'LL MAKE THEM PAY!" Issei shouted as he made his way out of the house, the earth shattering under him with every step.

-At the capital Lilith-

They all felt it, everyone felt the immense magic pressure as Issei blew open the city gates without a care for the guards who all just crumbled under the immense magic pressure he was releasing. The lower class devils seemed to just pass out as he walked passed with only one target in Issei's mind, he would eliminate the new satan factions leaders for they had gone against their promise. He would join them if they didn't harm his family but now, they had murdered all of them. As he reached the palace he snapped his fingers as magic circles appeared all around the city and before anyone could guess what they were for, the capital was surrounded by massive mountains that towered over even the grand palace. The doors crumbled down as he moved towards them and there he saw them, all perched up on their newly claimed thrones, the four satans.

"Issei, what is this about?" Sirzech asked as he rose from his throne.

"You know exactly what its about, YOU MURDERED MY FAMILY!" Issei shouted as he burst forward in a burst of speed towards Sirzech but was stopped just before he could reach the satan's throne by a green barrier full of different magical runes.

Issei punched the barrier constantly hoping to break through but Akuja's barriers were almost impenetrable.

"Issei we had to, they were consolidating too much power and still backed the old regime." Serafall explained trying to get Issei to calm down but she was met with a stare that made her entire body shiver with fear.

Issei didn't reply instead he reach out as his arm transformed into a red draconic gauntlet.

[BOOST!]

[BOOST!]
[BOOST!]

They all felt Issei's power double 3 times in a matter of thirty seconds as the ground around him began to crack apart and the whole palace began to shake violently.

He pulled his fist back as red energy began to swirl and form at the tip of his fist.

Once the energy was the size of a small ball he seemingly punched the ball into the barrier, which to the shock of all the satan's, smashed through the barrier and exploded, enveloping the whole palace in a bright red explosion.

-The Present-

Issei yawned as he and Gilgamesh passed through airport security. The plane ride had been a long 20 hours from Peru to Japan and he had barely slept while Gilgamesh had slept for most of the trip.

"You really should of slept Issei, you should be in your peak condition." Gilgamesh scolded Issei who simply shrugged.

"It's not like i could've of slept with you snoring" Issei teased as Gilgamesh blushed slightly and smacked his head with a magic infused hand causing him to wince slightly.

"I DO NOT SNORE" Gilgamesh shouted as they walked out onto the bustling streets of tokyo.

"My Lord your car awaits you" A strict voice called out from the front of the airport.

"Ah thanks Sasaki" Issei stated as he got closer to the vehicle. There, next to a simple Limo stood a man, around Issei's age, with pale skin and long flowing dark purple hair that was tied up in a ponytail. The man, Sasaki, was dressed in a black and white suit and wore fingerless gloves.
As Issei approached the back door of the car, Sasaki opened it for him and bowed as he entered the vehicle. Gilgamesh hoped in the front passenger seat as Sasaki walked around the vehicle and sat in the driver's seat.

"Is everything prepared Sasaki?" Issei asked the man as he relaxed into the leather seat.

"Accommodations have been made my lord and Mashu will be there to greet us" Sasaki informed Issei who nodded in response.

"I think I'll get some shut eye, wake me up when we enter the city" Issei informed the two as he closed his eyes falling into the darkness that was sleep.

-With Rias and Sona: 1 Hour Later-
Rias and Sona were talking at the Occult research club after school activities had coincided. They had just been talking about how Rias needed to hurry and find a way out of her engagement soon before she wouldn't be able to.

"Do you have a plan? It's only three months away." Sona asked her childhood friend who only sighed.

"Not really Sona….I can't think of one that'll lead to my victory…" Rias sighed as she gazed out the window into the darkened forest that surrounded the Occult Research club building.

Rias and Sona eyes both widened as they both felt a massive magical presence accompanied by an equally larger presence and a smaller presence enter the borders of the city.

"This magical power…..it's on par with the Satan's…." Sona gasped as a magical circle appeared next to her ear.

-In the Underworld-

"SO-TAN GET OUT OF THE CITY NOW!" Serafall shouted into her sister's ear through telepathic communication as the magic sensor alarms that had been placed around Kouh went berserk.

"W-why?" Sona asked as Serafall heard the sound of running through the communication.

"BECAUSE THE PRESENCE YOU'VE JUST SENSED ISN'T FRIENDLY" Serafall answered quickly as she readied a magical circle as Akuja and Sirzech arrived. She wasn't strong enough to deal with him, even though her power had grown she was not on the same terms of power as a Super Devil like Sirzech, Akuja and him.

-Back with Issei and Co-

"Sir wake up we are here" Sasaki stated as the car pulled up a 2 story house that was decently sized. Out the front of the house stood a light pink haired girl, whose hair was only down to her neck. She wore glasses and was wearing a formal secretary outfit.

Sasaki came around and opened the side door for issei so he could exit the vehicle. Issei stretched as he got out of the vehicle and gazed around at the houses around him.

"Nice place you found Mashu, well done" Issei praised the pink haired girl whose smile grew as she blushed slightly at the praise she was receiving.

"Thanks Issei-senpai" Mashu chirped happily as Issei and company walked into the already full furnished house. It was a very spacious house with not many walls in the main area. The lounge room, kitchen and dining room weren't separated by a wall.

"Everyone prepare for combat. We will be having visitors" Issei informed them as they all sensed two massive magical energies suddenly appear in the city, well specifically in the school grounds. Issei watched the front of the house as the two powers approached the house and soon he saw a familiar red mop of hair followed by a green mop of hair.

"Hello Mr Gremory, Mr Astaroth, or should i say Lord Lucifer and Lord Beezulbub" Issei greeted with a smile on his face but the venom laced in his words they could all tell he wasn't happy to see them one bit.

"Why are you here?" Sirzech asked dangerously as he glared towards Issei who shrugged in response before returning the glare.

"A bird told me that your sister is here and i couldn't help but wonder what she's like" Issei answered with a smirk as Sirzech flared his power and fired an orb of his power towards Issei in rage. Issei raised his hand up and channeled enough magic to cancel out the ball of destruction.

Before Sirzech and Akuja could move they had hundred of blades around them as they felt a power spike right next to Issei.

"Gilgamesh enough" Issei calmly spoke as Sirzech and Akuja saw a long blonde hair girl with piercing red eyes glaring at them with such pure bloodlust. She was wearing a black leather jacket, with a white shirt under it and black booty shorts. The bloodlust disappeared after Issei had told her to calm down as he stood behind and wrapped her arms around his neck protectively before once again glaring at both Sirzech and Akuja.

"I want you out of this city Issei" Sirzech ordered in a commanding voice but Issei just yawned.

"No. You don't rule over me Sirzech. I'm not one of your obedient lapdogs who listens to their 'Heroes' every word" Issei informed him with venom laced in his voice. A magic circle appeared on the ground near both parties with the symbol of the Baal clan in the centre.

"What do you want old man?" Issei asked as a middle aged man appeared in noble wear fit for a king.

The man just smiled as Sirzech and Akuja both looked at the man with some shock. Why was he here and more importantly, what did he want.
