A/N: Yeah, sorry for the late upload. Just came back from the hospital since I left home yesterday morning. My little sister had swelling on her face and her hands and my mom and I rushed to the hospital just to make sure it wasn't anything that might be fatal. Thankfully, it was just an allergic reaction and she was kept overnight to let the swelling die down but she's fine now. Had about four hours of sleep(very little from my usual 7 hours), so if there are mistakes, I'll probably fix them when I wake up from my nap.

Okay, now onto the story!

New Satan Stadium, Lilith, Underworld:

3rd Person POV:

"To be expected of my rival!" Sairaorg exclaimed as soon as he saw Isaiah eliminated his nine opponents in the blink of an eye, barely able to follow his movements as he quickly and seamlessly took care of them.

"That's right, gaki! Rule 4!" Okita shouted along with him, making Grayfia and MacGregor sigh as Sirzechs and the rest of his peerage chuckled in amusement at his words.

"…What just happened?" Seekvaira muttered in shock as she stared down at the arena, both her and Sona mind-boggled at what just happened. They knew Isaiah was talented, but to take down nine High High-Class opponents in the blink of an eye.

'That's Satan-Class level of power and the fact that he didn't even look as if he was trying. He's gotten far more powerful than I calculated.' Sona thought with a frown as she watched Isaiah smirk in satisfaction and walk out of the arena, the entire arena completely silent before it was broken by a roaring cheer from the common devils and the low-class reincarnated devils.

"He's gotten so strong." Rias muttered in awe, which was mimicked by Koneko and Gasper as they watched Isaiah completely dominate his opponents without even trying. And she thought she had gotten strong after asking her mother and brother for training tips.

She didn't even come close.

"What just happened, folks?! In the blink of an eye, Isaiah Azathoth has completely decimated his opponents without a single scratch and in just one hit! Is he actually going to win the tournament on his first try or will he meet his first proper foe in this tournament?! We'll see as we let the next group do battle!" The announcer shouted as ten more different devils walked through, Alivian the only one they could make out as he was dressed in a simple pair of black martial arts pants, a white muscleshirt and black boots.

"And in three…two…one…go!" It was over before his opponents could realize it, Alivian systematically taking them all down one by one as he delivered blows to their heads that completely knocked them out.

"And it looks like the Queen of the Heiress Agares, Alivian, has shown why he's her second in command as he annihilates his opponents! Who knows?! Perhaps this is the opponent to show Isaiah Azathoth that he is not the strongest anymore! I can't wait to see these two foes clash in the real tournament, folks!"

"As expected." Seekvaira said with a smug smile before it was wiped off as Rias spoke.

"Meh, Isa was faster."

"Alivian was just taking his time and playing with them. If he wanted, he could have easily defeated them just as fast as Isaiah."

"And also tire himself out in the process. Alivian is strong, but Isa beats him any day of the week."

"Alivian will win this tournament."

"No, Isa will."

"Alivian."

"Isa."

"Alivian."

"Isa."

"Should we stop them?" Kuroka asked Koneko and Koneko gave a carefree shrug as she leaned against her arm, nibbling on a cookie as Gasper just smiled.

"No, they usually stop after a minute or so." As if on cue, both girls huffed and faced back to the arena, Kuroka giggling as she leaned back in the chair with a happy smile. Isaiah had proven her innocence and made sure that both her and her sister was under the protection of a Satan in one fell swoop.

Just like he promised.

'Now, all I need to do is do my best to be the best Queen he needs.' Kuroka thought with a smile before a loud voice spoke.

"Ah, yes! He looks strong, but not strong enough to face Lord Isaiah!" Samson's voice boomed throughout the VIP box, making her sigh as the other pure blood devils glared at him.

"Samson, inside voice." Valerie muttered as she had her hands clasped on Gasper's ears, with him sitting in her lap, and she giggled as Samson gave a sheepish grin before nodding.

"And now, we continue on to Block 3's deciding match for who fights in the tournament!" The crowd cheered loudly as another group of ten fighters entered, regaining the attention of everyone as they awaited the battle.

Isaiah's POV:

In the Winner's Waiting Room:

"Exactly as I expected." I muttered with a smirk as I stared at the projection of where Alivian fought against his foes, completely taking them out without a scratch.

"You've gotten strong over the past few years, Alivian." I said as I turned around when he walked through the doors and he looked surprised at me knowing that it was him before he smirked.

"And so have you. That speed of yours haven't changed at all, I see." I chuckled at his words as I sat back down on the benches around the watching projector, grinning as I saw Akeno walk out with nine other foes. A few of them looked strong, but Akeno was smirking as she slowly walked out into the middle of the arena.

"And it seems the Queen of the Heiress Gremory, Akeno Himejima, has decided to make a target of herself as she walked right into the middle of the arena as if challenging the others to defeat her." Akeno giggled, as if agreeing with the announcer's words, and sparks slowly ran across her body as she licked her lips slowly.

"Do try to scream as loud as you can for me, please~" She whispered softly and her opponents glared at her before one spoke.

"How about you use that mouth to better use, Fallen slut?" I just stared at the one who spoke, memorizing everything about him as Alivian scooted slowly away from me, a bright yellow aura covering Akeno as she smiled at the one who spoke.

"I'm going to kill you." She stated in a simple tone and then turned away from him, leaving him slightly baffled as they all waited for the announcer to begin.

"Three…two…one…go!" As the match begin, Akeno raised her hands and numerous Gremory crests appeared around her, absorbing the blows and magical attacks from her opponents before she giggled sadistically as a large Gremory crest appeared above the fighting arena.

"Fallen Judgement." She intoned and electricity sparked in the air before nine lightning bolts flew from the crest and slammed into each one of them, completely scorching them and knocking them unconscious. I also felt faint traces of Holy energy in the one she used on the guy that taunted her and I smirked as they all slowly fell to the ground, completely knocked out and severely hurt in the case of Soon-To-Be-Dead guy.

"And just like that, Akeno Himejima has completely dominated her competition like the ones who came before her! Are the rookies of this year just monsters and will we see any more?! Let's find out as the next group of fighters come through!" Akeno giggled as she skipped off the fighting arena, through the gateway which lead to the Winner's Waiting Room as we waited for the next group of ten.

"Hey, beautiful." I greeted as soon as Akeno walked through the doors and she just waved at Alivian before plopping down on my lap.

"Hey, handsome. So, what did you think?" She asked with an eager smile, to which I chuckled.

"Nothing but amazing. I see you've been working on your Holy Lightning as well. Usually, an attack of that size would have eviscerated that idiot."

"Well, I didn't want to kill someone on accident, so I trained mostly in my control since I already had enough power to use it." I smiled with a nod before we turned back to the projection, where the fourth match was about to begin.

Time to see who the true monsters are.

An Hour Later:

"And these are the 32 fighters, who will advance to the next round tomorrow, when the round of 32, the round of 16 and the Quarterfinals will take place!" The crowd cheered at the announcer's words and Akeno giggled from where she was standing next to me, but I was focused on the real threats in the tournament. Akeno, Alivian and Tsubaki, who surprisingly decided to take place, were on that list in the top 10, but there were also a few more that I were wary of.

Sectaas Barbaros, the Queen of Magdaren Bael, the younger brother of Sairaorg and the former heir to the Great House Bael. He was a gray-haired man wearing a dark purple cloak and a suit of light armour under it. Attached to his right side was a broadsword with a dull grey scabbard.

Kuisha Abaddon, the Queen of Sairaorg's peerage. It allowed her to create dimensional holes around her that allowed her to store and release the attacks of her opponents whenever she wishes.

Bafeel Furcas, the sole Knight on Seekvaira's peerage, who was a Knight on Sairaorg's peerage. She was a woman in her early twenties with long straight chestnut-coloured hair, dressed in a simple black suit.

Beluga Furcas, a Knight on Sairaorg's peerage and the older brother of the aforementioned Bafeel Furcas. He was dressed in a suit of dark grey plate armour with a western broadsword strapped to his right side.

Coriana Andrealphus, a Bishop on Sairaorg's peerage and a former half-devil. She was dressed in her signature dark pink suit with the dark pink skirt and she had on a confident smirk as she stood next to Kuisha.

Misteeta Sabnock, the second Bishop of Sairaorg's peerage and the last member of the extinct Pillar House Sabnock with human heritage. He was a young boy with light green hair and violet eyes, wearing a white cloak with gold linings and having a dark purple wizard staff in his grasp.

Liban Crocell, the second Knight of Sairaorg's peerage and just like Misteeta, the last member of the extinct Pillar House Crocell with human heritage. He was a young man with blond hair and silver eyes wearing a set of bronze light armour, a sword strapped to the right side of his waist.

Ladora Buné, a Rook of Sairaorg's peerage and a member of the near-extinct Pillar House of Buné. He was a tall and lanky man with dark green hair and red eyes, dressed in a sleeveless brown shirt and dark green pants.

Gandoma Balam, the second Rook on Sairaorg's peerage and a member of the Pillar House Balam. He was an enormous guy, about 3 meters tall and his skin was a tan colour and covered in rock-like bumps that looked like rocks were sticking to him.

"Did Sairaorg's entire peerage decide to take part?" I muttered to Akeno and she stifled her laughter as I smirked before I looked up at the one I was the most wary of along with Alivian.

At 1,84 meters tall, he had short black hair and he had a light brown skin tone. He was heterochromic, with a green right eye and a bright blue left eye and was dressed in a simple dark green shirt, black pants and black boots. He looked completely bored as he looked around and his pointed ears twitching slightly as he noticed my eyes on him, smirking as he gave me a mocking wave.

Diamante Fleurety, the son of the former Lord of House Fleurety, the heir to House Fleurety, one of the Six Houses of Lucifer, and if that was not enough, he was also the Queen of Diehauser Belial, the Emperor and No.1 of the Rating Games.

The reason I was wary of him was because of the ability of House Fleurety, Smoke Manipulation.

Now, smoke manipulation might not be as cool as fire or water manipulation, but smoke can still suffocate you with ease without you even noticing it. Not to mention, the fact that he is used to fighting in thick clouds of smoke while it would be very detrimental to me.

In other words, I'll have to go all-out against him and take him down as fast as I possibly can before he can set anything up.

"And now, to organize the matches, we have the DERA to figure out the rankings."

"The what?" I asked in confusion as two of the attendants rolled in a machine and it had some sort of punching box on it, a monitor on the side of it. Akeno giggled before she explained.

"The machine Okita used to find out your rankings. Lord Beelzebub has upgraded and combined the four separate machines into one. You can now figure out all of your stats without having to go through all of the different processes." I hummed in an impressed tone as we were all lined up to take our measurements, with Alivian in the front, Akeno and I smack in the middle and Diamante at the back.

'Wow, now isn't that just a coincidence?' I thought with a smirk as Akeno was in front of me, giving me a teasing grin as if reading my thoughts and I rolled my eyes with a smirk.

*BBBBBBBBBBOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMM* A loud boom echoed throughout the fighting arena as Alivian punched the machine as hard as he could, standing back and awaiting his results.

[Calculating statistics…Strength: High Satan Class…Speed: High Satan Class…Energy: High Satan Class…Overall: High Satan Class] The crowd cheered loudly as Alivian nodded before standing to the side, waiting where the rest of the officials were.

*BOOOOOOOOOOMMMMM* Tsubaki looked slightly anxious as she awaited her results and the machine beeped before it spoke.

[Strength: Peak Ultimate Class…Speed: Mid Ultimate Class…Energy: Low Ultimate Class…Overall: Mid Ultimate Class] She sighed in relief as she smiled and bowed slightly to the attendants before walking to wait where Alivian was.

After that, no one was as impressive, other than Kuisha's Peak Satan Class energy, Bafeel's High Satan Class speed and Gandoman's Peak Satan Class strength.

Finally, it was Akeno's turn and she sauntered towards the machine, swaying her hips slightly and glancing over her shoulder at my eyes, that were completely fixed on her behind, an amused expression before she turned back to the machine.

*BBBBBBOOOOOOOOOOOOOOOOOOMMMMM*

I blinked slightly at the loud boom that was sent throughout the arena, Akeno giggling at my bewildered expression as she smiled and turned back to the machine, who began speaking.

[Strength: Mid Class…Speed: Mid Ultimate Class…Energy: Mid Satan Class…Overall: High Ultimate Class] My eyes were wide in shock as she gave me a happy wave before walking over to where the others were waiting, the crowd cheering loudly as I slowly walked towards the machine.

'Looks like she's far more stronger than she was in canon.' I thought with a smirk as I stopped in front of the machine, nodding at the attendants before turning back to the machine.

"In order for the machine to get your full capabilities, you must punch it as hard as you can while cladding your hand in your aura." The attendant explained and I nodded as I got into a basic punching position, my dark blue aura covering my hand as I took a deep breath before punching.

*BBBBBBBBBBBBOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMMMMMMMMMMM* I heard a few people yelp in the crowd as my fist flashed forward, a thunderous boom coming after and sending out a shock wave around me as the ground under me cracked slightly.

"Maybe I should have hold back a little bit." I muttered with a grin as the machine beeped rapidly for a few seconds before it finally began speaking.

[Strength: Peak Satan Class…Speed: High Minor God Class…Energy: Peak Satan Class…Overall: Mid Minor God Class] The crowd's cheer was nearly deafening as I smirked and raised my fist leisurely in the air, the cheers growing even louder as I chuckled and walked towards where everyone was waiting.

"You just have to show off, didn't you?" Akeno said with a smirk and I gave an unashamed shrug as Alivian chuckled at my bluntness.

"I see that part hasn't changed about you as well." He said and I grinned.

"Not at all. In fact, I'd say it's gotten even worse." He chuckled at my words before we turned back to where everyone else was testing their stats. After five minutes of people getting an overall of Satan-Class or below, Diamante was finally the only one left as he stood in front of the machine, a light grey aura covering his right hand as he pulled it back before punching forward.

*BBBBBBBBBBBBBOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMMMMMMMMMMMMMM* If my punch was deafening, then his was nearly devastating as it was a full 0.5 seconds before the loud sonic boom finally came, sending shock waves flying out and cratering the ground under him slightly. He grinned as he went back to his leisure slouch position, waiting for the machine to start speaking.

[Strength: Mid Minor God Class…Speed: Mid Minor God Class…Energy: Low Minor God Class…Overall: Mid Minor God Class] He smirked at the crowd's loud cheering, turning to give me a challenging smirk and I grinned as I felt my battle mania grew.

Looks like the tournament won't be as boring as I thought it would be.

"And with that, give us a few seconds, everyone as we determine the matches for tomorrow!" The announcer said as the announcer pressed a few buttons, a large screen appearing out of the wall above the announcer's booth and turning on. All 32 names appeared on the screen before it was shuffled rapidly, the names flashing over and over until finally, it stopped.

"Oh, now isn't that fun?" Akeno said and I looked over to where her name is before I chuckled.

Match 8: Tsubaki Shinra vs Akeno Himejima

"Maybe I can finally get that bet from her."

"What bet is this?" I asked and she gave me a mysterious smirk.

"You'll find out after the tournament. For now, you have something else to worry about." She said as she turned my head and I looked at where my name is before seeing who my opponents was and grinning as I turned to them. Gandoma gave me a nod and I nodded back with a smirk before looking back up at the monitor.

Match 16: Gandoma Balam vs Isaiah Azathoth.

Oh, looks like I'm destroying someone's dreams tomorrow.

A/N: And now we finally get into the real tournament and our first battle is finally starting.

Yeah, don't have anything to say other than that, so read, enjoy, review and until the next chapter.

Ba-Bye~!
