"You'd rather die, huh? Then I shall grant your wish." He pulled his arm back and proceeded to kill him. Vali had accepted his fate. The blad stopped in front of Vali's face.

"Hm? Ahh! Sirzechs Lucifer. It's you." Regalzeva said those words casually to an infuriated Sirzechs.

"There you are asshole. Walting in my place. Killing my people. And now, killing the ine can't even stand anymore. If you have the balls enough, they fight me. ME VERSUS YOU and only us." Sirzechs replied.

"Sure. Why not." Regalzeva replied. Sirzechs then released his hand and took his fighting stance.

"You said you wanted to fight me and only me, without the other 5 interrupting our fight. That was it, yes?" Asked Regalzeva to clarify and to keep the policy fair.

"That was exactly what I said. Why, you have plugs in your ear you IGNORANT FUCK?"Asked Sirzechs with a mocking tone.

"Then it's settled." Regalzeva said. Sirzechs twitched his brow in annoyance after hearing the phrases 'warmup match. "While I have a warmup match with the 'Honorable Devil king' Sirzechs Lucifer, you 5 go and continue the search for Issei Hyoudou." Regalzeva ordered his subordinates.

"No, they are staying right here. I mean m, I've already said that Issei is not here. Then why waste your time finding him?" Sirzechs objected.

"That's our problem. Why are you getting so busy about it? Perhaps, if he isn't here there then there shouldn't be any problem with you. The density of population of population is almost twice as that of earth. Just the death of a few million people shouldn't be that much of a problem for ya. Trust me, you will recover the no.of in just a few years." Regalzeva said it all casually. But for Sirzechs, it wasn't casual at all. He was both shocked and was more mad at him.

{Alright, the population estimate just came from my brain. So, please adjust with it. PWEASE }

"You wretched scoundrel. How can you be so cold-hearted?" Sirzechs said.

"I just am. We are wasting time. Let's begin it, shall we?" Said Regalzeva. He then rotated his head 90 and nodded at his subordinates, gesturing them as a sign of order to leave that place immediately. They did so. Sirzechs then said.

"Alright, but wait just a second." He then walked up to Vali and then put him on his shoulder. He then disappeared and reappeared a second later.

"I am ready." Said Sirzechs.

"Alright then, bring it." Regalzeva replied as he gave the signal to start the fight.

"HYAAAAAAAAAAA!" Yelled Sirzechs who charged at Regalzeva. Regalzeva just stood there, waiting. As soon as Sirzechs reached near Regalzeva, he started throwing punches at Regalzeva. All thise were enough to shake the ground and even break it apart. But, Regalzeva didn't even move a micronmeter and took all the blows head on. Although Sirzechs was not surprised at all as knew knew it was coming, Regalzeva was even scratched after all those fatal blows. Any other opponent would have gotten decimated if theh were even touched by Sirzechs. But, Regalzeva was undoubtedly and expectedly different.

"Come on Sirzechs, you have gotta do more than that to even make me break a sweat." After saying so, Regalzeva deflected Sirzechs's punch with his left back lower arm, increasing the distance between the fist and his face. Then he curved back his middle finger with his thumb and placed it on Sirzechs's forehead. He then flicked Sirzechs which sent him flying backward. Sirzechs then gained his stability back and stood back on his feet.

"Damn, that was just a flick?" Thought Sirzechs. He then for.de a sphere in his his and said.

"Ruin the extinct." This was the very attack he used to eliminate Creusery Asmodeus. He knew that it wouldn't do shit to Regalzeva. But at the same time, he also thought that it was at least worth a shot. Soon, a scarlet red and black coloured sphere surrounded Regalzeva. But he did not seem to be impressed about it.

"Seriously? Like, do you think that I know nothing about you and your past? Or are you looking down on me? Because if you are, then I would be glad to say you thank being lokked down makes me mad and boy o' boy, you have not seen what happens when I become mad." Regalzeva said it as a sign of warning as he canceled Sirzechs's attack with releasing a tiny bit of his aura. Sirzechs sighed in sorrow, he knew that that attack was going to be an utter failure. Now, he had decided. He had been training for this day. Though 30 years would have given him more time to test it. He had decided. The Underworld then began to shake. It was almost going to break apart. Sirzechs bent down a little and took a fighting stance. Just like the one Goku took before fighting Nappa to increase his power level to 8000. He then started gathering deep crimson aura around him. It was like the Underworld was breaking apart. He then with a uell transformed. Filling the entire Underworld with crimson aura.

"HYAAAAAAAAAAA!" When Regalzeva opened his eyes, he saw Sirzechs's full body had become red. This was his final form,'The Red Satan'. It picked Regalzeva's interest. He started to grow excited now.

"YES! That's what I am talking about." An exicted Regalzeva said. They both charged at each other. They pulled back their arms. They then released a punch at each other's fist. As soon as their fists collided, the entire Underworld shook up by a large scale. It was like an earthquake, deadlier than the Chinese Shaanxi Earthquake of 1556 C.E. A massive chunk of area got completely obliterated. The two rhen proceeded to continue their fight in hand to hand combat, in which Sirzechs was a master. His combinations of punches, kicks, pinning moves, locks, joint locks, pressure point puncturing, breaking joints, counter attacks and tackles were formidable. It was quite visible on Regalzeva's face that he was having trouble countering his moves. Sirzechs was also in short time intervals using minor destruction attacks. Regalzeva was no less. He was also extremely skilled 8n hand to hand combat. Sirzechs was also, on the other side, sometimes faced trouble breaking his combinations. No doubt how he was able to defeat and kill Great-Red. But unlike Sirzechs, Regalzeva was not using any powers of his. Sirzechs knew that he needed maximum of his power and potential to beat Regalzeva. But he also knows that he had mastered his Red Satan form, but he had a very low endurance to it. If he uses more power than necessary, then his stamina would run out. They were moving very fast. Faster than light in the sky. In the sky, they kept moving from here to there. From one sot to another spot. Regalzeva, at that point, knew that this was the best battle he had ever experienced. Then they came down to the ground and started punching each other at a very fast rate. Most of them would miss due to their agility. But some would him them. Regalzeva, at one point, got outsmarted by Sirzechs as Sirzechs bent down. Regalzeva thought that he would attack from below. But instead, Sirzechs jumped and gave him a nice axe kck to his face. He was really impressed by Sirzechs. He knew that Sirzechs was weaker than Great-Red, but it turned out to be just the opposite. Great-Red was now like a kid for Regalzeva.

"Sirzechs Lucifer. I bet that the time of 1 year and a month, you didn't waste a single second in other activities but trained yourself and pushed your potential. I have fought many opponents in my entire life that I have spent for my conquest. I Regalzeva, the Supreme God of the Evie Etoudie, declare you the strongest of them all." Regalzeva acknowledged Sirzechs's power and declared to be the strongest opponent he had ever faced in his entire life. Sirzechs smiled and returned his opinion.

"Than you, I am very honored to be praised by one of tge strongest Gods that have ever existed. But don't forget that your positive acknowledgment won't make my mind change. I would still kill you if I get the chance." After hearing Sirzechs out, Regalzeva smiled and replied.

"I never said that I have forgotten the fact. So, do it Sirzechs. Hit me with everything you've got." Regalzeva was now savoring the batlle and why not, he was going to destroy the Underworld if he didn't find Issei anyway. They kept on fighting for a couple of hours. Sirzechs was now getting fatigued. He was shocked how Regalzeva was still stand in front of him just like before, INTACT. On the other hand, Regalzeva was now getting bored. When Sirzechs launched a smalll ball of destruction at him, he let it hit him. Inside the smoke, he was yawning. Jus then, a plan came to his mind. He just wanted to end this fight already. He had monitored Sirzechs from time to time. In that, he had realized Sirzechs's weakness in his current form. He came out of the smoke and called Sirzechs.

"C'mon now Lucifer, this is starting to bore me. Yeah! How about this, I will now end you and fuck the Underworld."

"Go fuck you sister you sloppy bastard. Don't waste my time, I have other things to take care of." Sirzechs replied. Regalzeva knew something like that was coming so he countered it to anger him even more and compel him to use his full power.

"I don't have one. Oh speaking of fucking, you here have a sister don't you?" Sirzechs after hearing this was not at all in a good mood anymore. He understood that what Regalzeva was trying to say.

"What are you getting at?" Asked an infuriated Sirzechs.

"I mean you said it. I don't have a sister. How about yours?" Regalzeva said so, to make Sirzechs unleash the beast inside. The would atleast make the fight more fun for him.

"YOU INSOLENT. INSIGNIFICANT MOTHERFUCKER! You will regret every single phrase you've said. No you will reget every single life choice you've made. I will kill you. I will rip you apart with my bare hands. You hear me? WITH MY BARE HANDS!" Sirzechs's anger was beyond control now. He knew he wouldn't be able to fight for much more longer, if he uses more of his power. But Regalzeva had crossed all lines. Sirzechs started powering up to his fullest. The entire Underworld was going to be ruins at this rate. But for Regalzeva, it was just another fun activity. Suddenly, he felt a line striking his nerves. He felt a powerful and dark chill going down his spine. He knew it was something very deadly and he was certain that the power didn't come from Sirzechs. After saying what he said to Sirzechs, he felt like he had become a bloodlusted and deadly predators prey. It felt very unnerving like someone very strong and powerfulwas upset with him. All the elders and the experienced people could also feel the same way Regalzeva did, exceptSirzechs, who could also sense energies, but was just too focusedon powering upband anger, that he didn't feel the power. Regalzeva knew that his near future wasn't going to be a sweet and easy one. After what he said said about Rias, he knew that going to pay dearly. Sirzechs, after increasing his power to 100%, suddenly appeared in for of Regalzeva. He couldn't even trace his movements and speed anymore. He then got punched in the face, which made him suspend in air.

"I will not let you live any longer." Said Sirzechs. He didn't care about skills and techniques anymore. He just used his power and strength. Regalzeva didn't get time to react and Sirzechs kept thrashing Regalzeva with all his might. Finally, Regalzeva was starting to bleed. Sirzechs sent him flying into air and then, he quickly appeared on top of him and slam hum on the ground. As Regalzeva landed, Sirzechs also came down and started punching him on the ground. The energy transfer had broken every single bone inside Regalzeva's body. Regalzeva had enough of that now. We wouldn't allow himself to be killed in the couse of having fun. He regenerated all the bones that were broken. He then pushed Sirzechs away. Then said.

"Really Sirzechs, you are the real deal. I gotta give you that. 1 million battle power of an opponent is the highest I hsve ever had to face. And the opponent is you. But still, it is not enough."

"Even this is not enough? What can I do to stop this monster." Sirzechs thought. He knew he won't be able tobl to face Regalzeva for more than a few minutes now. Regalzeva then started to power up he released a bit of his aura. He then said.

"Take this then. 1.5 million battle power. But don't think 'that only this much?' This is only 0.5% of my overall power." Sirzechs then was shocked to core. He was completely sure that he was not even nearĺy enough to stop Regalzeva. He was now a child in front of Regalzeva.

"1.5 MILLION?! And that is now even 1% of his strength. What truly is he? He insulted my sister, killed my people, and yet I can't do anything about it. I am useless. A half-assed piece of garbage." Sirzechs was starting to tear up now. There was nothing he could do at this point. He started to repent. Just then, Regalzeva yelled.

"Here I come Sirzechs."

Transitional Scene change {An energy blast instead of Regalzeva}

An energy blast exploded on the barrier surrounding the middle Underworld circle.

"AH! How much effort does it take to break this thing." Gvardora exclaimed.

"Hold your horses Gvardora, we need to think of a plan to break this thing." An annoyed Bebeve Su scolded Gvardora.

"He is right come here you all. We need to discuss things." Ordered Haz Illyus.

Scene change - Inside the barrier

"We need to do something. This barrier will not keep us safe forever." Sairaorg said.

"Wait. Shemhazai. Are you done?" Asked Azazel.

"Just a moment. Yeah... Yes, sir. Thank you, sir." Shemhazai was in a call. He hung up the call and looked up at Azazel with a smirked. Azazel, in return, also smirked and asked.

"It is finally done, isn't it?" Shemhazai then replied.

"Yes. Will you announce it then?" Asked Shemhazai. Everyone was curious about the topic that they were talking about. Azazel then replied.

"You're the governer general of the fallen angels now. Its your job." Shemhazai cleared his tone. He then started to spread the news to everyone inside the barrier.

"Everyone of my comrade who are present here and now today. I have a great news for you all today. So, please be patient. Though there are no seats available right here right now, pleae be seated. The call was from the Great Son Goku. The man named Issei Hyoudou and with the Welsh Dragon Ddraig has been dispatched and will be arriving here in less than 5 minutes."

Everyone was overwhelmed with joy after hearing the news. Their eyes shined with hope again. The news also got spread quickly in the Underworld. All the normal people felt safe and children were screaming Issei's name. Suudenly a glass shattering aound was heard by al inside the barrier. The break had shattered from a group attack of Haz Illyus, Rugatimu, Gvardora and Bebeve Su. The ones inside the barrier, which now had shattered, were now afraid. The 4 outside then yelled together by accumulating an enormous amount of energy again. The others in the Allied forces were way either tired or afraid. So much that they couldn't even move anymore. The 4, together, held a massive sphere of Evie energy. On one end, the 4 held the sphere in their palms. On the other end, the Allied forces stood still as they could do nothing anymore. Haz Illyus then said.

"Play time's over children. Now be gone." As he finished saying, the 4 launched the sphere at the Allied forces. The sphere moved towards them all at a very high speed. The Allied forces made as many shields as possible to protect themselves. Suddenly, the sphere exploded in mid-air.

BOOOOOOOOOOOOOOOOOOOOM!

The sphere created a very noisy explosion sound. When the smoke cleared, the 4 could see a man floating above the Allied forces. He must've been the one who stopped their attack. But there wasn't a single, small scratcj on him. The 4 were shocked.

"Who are you now?" Asked Haz Illyus.

Scene change - Back to Sirzechs and Regalzeva

Regalzeva came flying at Sirzechs while holding his fist back. Sirzechs crossed his arms releasing as much aura to defend himself. Regalzeva then punched Sirzechs's arm. At first, Sirzechs could block his attack buter after a while, he started losing his balance because of Regalzeva's extraordinary strength. He the fell backand started rolling on the ground backwards. He then shook his head to regain his sense and started increasing the distance between them. He had no choice but to give it one last shot. He started accumulating all the energy that was left in him and started converting the energy into energy of destruction. He created a massive amount of destruction energy. Regalzeva then smirked.

"Now this might feel like something." He thought in himself. Sirzechs was done creating the energy of destruction he need. The energy appeared to be a red and black, shapeless aura, which was continously circulating. Sirzechs then yelled.

"Have this for your amusement.

REVENANT'S NIGHTMARE!" He released all the energy that he had created. The attack stretched widely and grew huge. Regalzeva just stood at his spot, not even caring to move his body an inch. He gladly welcomed Sirzechs's attack. The energy of destruction then took the shape of a face. A face like Eren's titan but a looked lot more creepier, dangerous, and had more sharper teeth. The attack then colloided with Regalzeva. It didn't create any explosion, but it appeared to be merging with the ground. Like it was eating the ground. It kept going inside the ground. Sirzechs then lost his Red Satan form and went back to his base form. Then a voice came from inside the attack.

"That's it huh? All that powerup for just a lame attack like then. And I thought that this one would at least make me feel something. " Regalzeva emerged from the attack by canceling it. He then came in front of Sirzechs at light speed and punched him in the gut.

"GUAAAAAAH!" Sirzechs vomited blood out his mouth. Regalzeva then pinned him on the ground. Regalzeva landed on Sirzechs's legs, breaking them instantly.

"AAAAAAHHH!" Sirzechs screamed in pain. Regalzeva then proceeded to hiting Sirzechs with hard punches on his torso and face. Sirzechs couldn't even move anymore. He was fatuiged from fighting for so long and now, he got beaten up so badly that he was half dead at this point. Regalzeva then tossed Sirzechs in the air. Regalzeva then appeared above Sirzechs's back and elbowed him on his back, completely shattering all bones in the vertebral column. Sirzechs opened his mouth widely, with an expression of pain on his face. He wasn't even in the shape to scream to let out his voice. Sirzechs fell on the ground. Regalzeva csme down and stood , facing his back in front of Sirzechs's face. He then turned towards Sirzechs and said in a mocking tone.

"Well Sirzechs? I thought you said you'd kill me. But I am still standing in front of you. You know, I was a little disappointed from the fight that we just had. But, I guess you gave you all which is the most important thing in any type of competition. I really appreciate that." In response, Sirzechs groaned at him, while giving him a killing intent. Regalzeva then continued to taunt him.

"Still got that look huh? I really meant all that I said." Regalzeva then grabbed Sirzechs by his head and pulled him up. He then said.

"Any last wishes Sirzechs?... I guess no. I hope they all remember you. " Regalzeva closed his fist and surrounded his lower arm with his Evie aura. Just then, a voice from behind spoke up.

"Hey. Mechanical Fuck Face!" As soon as Sirzechs heared the voice, his eyes widened as he knew this voice. Regalzeva then got annoyed as it was the second time anybody had interrupted him when he was so close to killing someone. He then turned back and asked.

"Who is it now?" The peson was none other than Issei.

"I am the one you've been looking for. I am the Red Dragon Emperor, Issei Hyoudou. "

Issei replied. Sirzechs finally smiled happily. Regalzeva then threw Sirzechs away. Issei without even wasting a second, appeared behind Sirzechs and held him in his arms. After seeing Sirzechs condition. You could tell by just looking a his face that Issei was pissed. Regalzeva then realized something. He asked.

"Wait, I don't recall telling you that I was looking for you? Who said that to you? Issei then replied.

"Your subordinates did." Regalzeva just then realized that he couldn't sense the life force of his subordinates. He just got too excited while fighting Sirzechs that he forgot his subordinates.

"That's right. Where are my subordinates? What did you do to them?" Regalzeva asked

Chapter End

{Note - Issei is not 38 years old. He looks like a teenager and is actually 18 years old.}
