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

"What did I do to them, you ask? Well... I killed them."

"WHAT!?" Regalzeva exclaimed in astonishment.

" Issei starts telling about the events that happened just a few minutes ago.

Flashback:

"So, who are you now?" Haz Illyus asked

"You guys surely are colorful. The executive class one. The Staff Officer Deputy of Regalzeva, Haz Illyus. The loyal and intelligent, 3 meter tall and slim one with 4 arms and a hue of blue and purple mix, the Sky General Bebeve Su. The five meter tall one was with 3 eyes, the one who picked Hades and Angra Mainyu after Vali's team was defeated. And last but the least interesting one, all brawn but zero brain, Gvardora. Nice to meet you all." Issei greeted al 4 of them. Gvardora was a little pissed after being called zero brains.

"Who are you calling 'Zero Brains' you weakling." Gvardora said with a tone filled with displeasure.

"You, of course. And you should keep that 'Weakling' title for yourself. And now, for your question, Haz Illyus. My name is Issei Hyoudou, the Red Dragon Emperor of this generation. " Issei mocked Gvardora, then replied Haz Illyus. Issei was currently wearing the Gi, with looked exactly like that of Goku's, but the colour of the Gi was Crimson Red instead of Orange and his inner shirt was Black in colour along with his wrist band and belt. His boots were Obsidian Black in color, with a few Red lines in between. All the others under him now felt safer as Issei had entere the battlefield. Gvardora was more pissed after being mocked by Issei, but after hearing upon his name, he idiotically spilled all the beans.

"Ahaa! Finally! We don't have to search for you anymore. No more wasting energy, one killing these worthless people. And why do they love you so much. They didn't want to speak about your location and gave their lives to keep it a secret. Even your buddy, the White Dragon Emperor, Vali Lucifer, who I kept thrashing, until he was half dead, refused to utter a simingle word about you." Issei's eyes narrowed, and his brows ticked after hearing all that. He was totally pissed. He then closed his eyes and took a deep breath, and he exhaled as he calmed down and smirked while thinking as he looked at Gvardora.

"Alright, He is my first blood of the day." All of his comrades, especially Bebeve Su, got annoyed after Gvardora told everything that was important information.

"Hey! You don't go telling around the secrets of your own team to your enemies Dammit. He really is correct. You don't have any brains." Said a displeased Bebeve Su. Gvardora was going to retaliate against Bebeve Su's statement when Issei spoke up as he descended down on and stood on a rock.

"Hey you! Gvardora. You said that I am a weakling, isn't that right? Then come and try to defeat this weakling. You fucked up mechanical piece of horseshit." Issei taunted Gvardora. Gvardora, following his personality, got furious and flew towards Issei.

"DAM YOUUU!" He yelled as he got near Issei and started throwing punches at him.

Issei, like a badass, just moved his body a little bit in all directions and dodged all of Gvardora's punches. Everyone, literally everyone that witnessed the scene, was in total shock. Gvardora got more frustrated.

"WHY YOU WRETCHED." He growled as he pulled back his fist. Issei then moved his body at 90 degree and closed his left palm and formed a fist and lowered his lower arm below his waiste. He then clised his other palm and formed a fist in his right hand and then. Punched Gvardora in his sturnum region.

"BHRWAAAAH!" Gvardora vomited blood out his mouth. He then proceeded to look down and when he did so, he was shocked.It wasn't just a feeling, it was real. Issei had punched a hole through his chest. The sound made by the punch, when it hit Gvardora's chest, was very loud. Issei, without was anymore time, proceeded to punched his face. After seeing the scene, everyone was both, horrified and got cheered up. Issei's punch didn't just give an impact, but blew his head away and he was beheaded.

BOOOOOM!

Gvardora's body exploded, leading to his demise. His comrades were shocked as he was taken out so easily. Vali definitely and of course grunted at the sight. He now knew that he was no match for Issei now. He couldn't even make Gvardora break a proper sweat in his Maoufication while Issei, in his base form, had finished Gvardora off in just 2 hits, without even trying hard. The other three had planned a gangbang on Issei. They started attacking Issei with all their might and with all they had. Issei just kept moving standing on the same rock and dodge all the physical attacks. Then jumped from here to there, dodging all the energy attacks. Rugatimu, being the strongest of the special squad, shot a powerful energy blast. It created a large explosion. But to his surprise, Issei appeared on his left side.

"WHAT?" Rugatimu explaimed. Issei grabbed his head and flew towards Bebeve Su. Issei made Rugatimu's body collide with Bebeve Su's and did the same with Haz Illyus and then flew towards the ground at high speed.

"What do you intend to do with us?" Bebeve Su asked.

"I will make you atone for your sins. The innocent people you will kill. The innocent children who are the future of the Underworld. This Devilicide will end right here and right now." Issei replied.

""No you can't." Rugatimu and Bebeve said.

"That's why I never want to fight." Haz Illyuz said. Issei then threw them on the ground. Their bodies stack one by one and one above another as they are well on the ground. Issei then flew high above. He then extended his hand and formed a small of ki. The 3 looked up at him. Their eyes widened and filled with fear.

""AHHHHHHHH!""" They all screamed together . Issei launched the ball in the form of a ki blast. The ball was completely transparent. As soon as the sphere touched the ground.

BOOOOOOOOOOOOOOOOOOOOOOOOM!

A massive explosion occured creating 2 mushroom clouds, one above another. The smoke cleared and all that could be seen was a massive crater. No sign of the 3, explaining that the 3 had been erased from existance completely. Issei then stopped telling the story to Regalzeva. But he kept remembering what happened next. Issei then turned back and landed in front of his comrades.

"So? You finally decided to show up, didn't you?" Azazel said.

"Fortunately, yes. What would you guys do without me?" Issei gave and sarcastic reply. Rias then stepped forward and said.

"I knew you you would come back." She was relieved to see him.

"Of course, I had to." He responded. He then walked up to Asia who was currently healing Vali.

"Ise-san?" Asia was expecting something from Issei. Issei replied

"Hey Asia hope you're doing alright." Asia then smiled and nodded. Issei shifted his gaze to Vali.

"Hey Vali, you don't appear to be in a good shape do you?" Issei asked with a wry smile on his face. Vali looked up to him and replied.

"Hyoudou Issei, you sure have grown. More jacked and taller. Yeah, what else? You here to show off that you can fly without wings now and can do what even I can't?"

Issei proceeded to throw Vali's words back. The same words that Vali said to him 2 years ago.

"No that's no the reason I've come. Hey Vali? Fate can be cool isn't it? You said that you were a miracle because you had the blood of Lucifer, making you 50% Human and 50% Devil and were lucky enough to be possesed by the Vanishing Dragon. But let me remind you something. I, Issei Hyoudou, have a father who is completely human, and my mother is a pure blooded Saiyan. But, I was born 100% Human and 100% Saiyan. The rarest case of a hybrid birth. I wanna tell you that I am the actual miracle here. I even got possesed by The Welsh Dragon. So, as a being, I am far superior than you Vali." Vali upon hearing Issei words realised that that fate really can be cool.

"Tch." Vali said out of annoyance. Azazel then decided to get in the middle their rivalry.

"C'mon you 2, this is not the time for this. Issei if you have that, give it to Vali. And Vali, you, without asking any questions, will do exactly what Issei says." Azazel ordered the 2 of them. Issei that put his hand in his pocket and took out a bean from there.

"Here Vali, eat this Senzu bean. This will completely restore your health, stamina and strength back to full." Issei threw the bean at Vali. Vali caught the bean and stared at it for a couple of seconds. He then proceeded to eat eat. Upon chewing and then swallowing it, could stand back up. His mind was completely blown. What Issei said was true. He felt like he had a completely new body now. Issei then turned around and asked.

"What is the kill toll though?" Kiba then responded to his question.

"Something around 269,420 people."

"Bh- Ahem." Issei waams going to burst in a laughter upon hearing the number. When Issei looked around, his comrades had their eyes narrowed. They definitely noticed that Issei was going to laugh and they didn't find that funny at all.

"What's so funny?" Riasked asked in a serious tone.

"What's funny?" Issei diumb played the situation.

"Don't play dumb. I know you were going to laugh." She said.

"No I wasn't." Issei still was trying to protect himself by playing dumb. That is when Vali realised something. He then spoke up.

"Hey Issei, may I ask why is your right eye is black?" Everyone then looked at Issei eyes. That right! His right eye was black unlike his left brown eyes. Issei then put his fingers under his right eye and said.

"Oh this? This is my Tomeigan aka. The Eye of Transparency."

"WHAT?!" Everyone around him questioned in shock. He then started explaining the thing to them.

"Yeah. See, the thing is-"

Flashback in Flashback

Issei was sitting on a chair near the entrance of the 'Bizarre Space'. His training had finall finished he was holding his knees while heavily panting. That's when Goku and Vegeta came near him. Goku then said to Issei.

"You did it Ise. Your training is finally over." Issei nodded. He was wearing the average saiyan armor, the blue spandex with a chestplate one. Vegeta then said.

"Congrats boy. Now let me tell you something. Have you noticed something? Your right eye is black in colour now." Issei, upon hearing Vegeta, rushed near a mirror. Yes, the 'Bizarre Space' gives the user inside whatever they wish near the entrance {My imagination }.

"HEEEEEEEEEEEH?!!" He screamed. Goku then eased Issei.

"Don't worry, Ise. Nothing wrong has happened to your eye. It's just an upgrade that we asked from the Namekian Dragon Porunga. I mean Dende asked it while you were taking a short break from training. "

Vegeta continued from were Goku left off.

"Yeah. That eye perhaps, will make you stronger. That is called the Tomeigan aka. The Eye of Transparency." After hearing what he said Issei made a lecherous face and thought.

"The Eye of Transparency. I can now also see the package inside the clothes of women before usind Dress Break hehe. Finally, another upgrade that will be going to help me a lot." He also started drooling. That's when Goku interferred.

"No Ise. You won't be able to see boobies through it. We now you kid. We know exactly what you think and when. That eye will help you to see through your opponents abilities. It will also warn you 1 sceond before your enemy will use his/her abilities with full description of it." Issei was a little disappointed, but it works the thought. Vegeta then said.

"Now, let's discuss about the Regalzeva guy's abilities. Firstly, the man is invulnerable to any supernatural attack except of the higher level being like us Saiyans. Bastard doesn't even know that we exist. Secondly, he can toyed around with reality however he wants and can also defy reality by bringing anything up that wasn't present there. Your eye has also an ability to counter his. Thirdly, he has an access to 4th dimesion and higher. Fourthly, he is weak enough to destroy or dismember a timeline. Compared to us, who can destroy many Xenoverses, Universes and other together. He also has a control over gravity, which is not a big problem for us. We can move even in zero gravity and you, just have finished training in 1000 times normal gravity. His limit is 500 times normal gravity. He also can survive if reality is destroyed without losing his memories or even time stops at a Multiversal level, it wouldn't affect him. He also has an ability to draw power to extract energy from the violence he has created or even when hurt by others and also can absorb energy from people. He can form any mechanical being he wants but it absorbis a lot of his energy so he avoids doing so. He can electrically created sucha a barrier which impenetrable from other supernatural attacks. At you current strength level, you might have to try hard to break it but you will be able to break through. He can form heavenly weapons, which a big disadvantage for you. You, because of being a devil, have to be careful and dodge ebery single of those attacks. He can also destroy souls, which a very high tier ability only a few of the stronger beings can survive this ability while their bodies will get destroyed.He can travel through cyberspace that is spaces beyond virtual reality. Your eye will warn you before he does so. His combat skills are mid high level. Compared to your current combat skills, you can overpower him. And yeah, after he absorbs one's power, that perticular being will not exis anymore. So, be careful. He gets fueled by his Evie Aura which is the main source of his power And last but not least, his attack pottency and destruction capability increase when negative emotions while fighting him, making him stronger." Issei quietly listened to all that Vegeta said. He then got up and thanked him.

"Thank you, Vegeta-sama, Goku-sama, this means a lot. Now I should get going, the Underworld world needs me."

"For sure. And can you please cut the formalities? Just Goku and Vegeta, alright?" Goku said. From behind Ddraig had also finished his training.

[Wait up partner. I am also coming.] He said. Issei opened the door as he and Ddraig stood side by side. As Goku spoke up again.

"If you want to change your clothes, ask Piccolo. And Ise?" He called from back. Issei turned back.

""Good luck."" The 2 of them wished him luck. Issei nodded as he and Ddraig exited the space. Vegeta then said.

"Kakarot, contact Shemhazai. "

Issei stopped explaining things to his comrades. Issei then turned and faced the battlefield as he heard someone saying something that infuriated him before coming to Underworld. He then said.

"You guys stay here, Vali and Azazel-sensei will come with me." The 2 agreed to him. He started walking when someone held his hand. When he looked back, ot was Rias.

"We girls have an order. You better come back in one piece, got it?" She said Issei smiled and replied.

"Yes ma'am." The 3 then departed.

"So, that's how it was huh? But what about the 4th one?" Regalzeva smirked and asked asked.

["You talking about this one? Durmado was a real weakling. Just one shot."] Ddraig replied him while holding Durmado's severed head in his hand. He then dropped his head. Issei was currently feeding Sirzechs a Senzu bean. Vali and Azazel had also arrived. Sirzechs stood back on his feet.

"Than you Issei." Sirzechs thanked him. Regalzeva, with his smirk on the face, said.

"Well well. 4 on 1 it is. Let's see who's gets the win." Issei objected him and said.

"No, they are just audience. You will fight me an me alone." Regalzeva was surprised at beginning then smirked and said.

"Alright. 1 on 1 it is. But they are free to join the fight if they like." Issei then lowered his head and said.

"Hey Regalzeva, you said something 'bout Sirzechs's sister weren't you. Well, there a bad news for you. She is my master and also my future wife and Iam the only one who can bang her." Issei's body started producing crimson aura he raised his head and gave Regalzeva a death stare as he continued. "You will pay for everything you've done. BALANCE BREAK!" He yelled Ddraig from his Boosted Gear yelled.

["WELSH DRAGON! BALANCE BREAKER!"]

{Note - Ddraig is still present in the battle in his human form. It's just the normal voicelines that is remaing in his boosted gear.}

Issei suited up in his scailmail. He then, knowing Regalzeva's strength, decided to go all out as the Red Dragon Emperor. He started chanting.

Issei:The Crimson Red Dragon dwelling within me, awaken from your dominance

Ophis:The Crimson Heavenly Dragon I possess within me, rise up to become a King and roar

Ophis:The jet-black God of Infinity

Issei:The glorious God of Dreams

Both:Watch over the [true] forbidden existence we shall become that transcends the boundaries

Both:Thou shall dance within our perfected radiant inferno!

Ddraig: [TRUE DRAGON DEIFICATION!]

As they finished chanting. Issei was uncovered from the Crimson Red aura and Jet Black aura. The armor becomes colored in a mix of Crimson and Jet Black, and a second pair of Dragon wings appear on its back, totaling in four. The armor had the same organic characteristics as theJuggernaut Drive. His jewel ms hsd Ouroboros Dragon. He had aura of Devil, Dragon and God. He then said.

"Let's do this."
