The confrontation of Issei, Rias, and Koneko against Kuroka and Bikou leaked to everyone at the party and even reached the higher ranks such as the Maous. Concern about attacks from the Khaos Brigade kept increasing more and more, they seemed completely unrestrained.
Sirzechs managed to calm everyone down when he reminded them that he was the strongest demon alongside Beelzebub, the demon who could fight even against Gods.
"You don't need to fear, Beelzebub and I can guarantee that you will be defended with everything we have, with our honor as Transcendental Demons." (Sirzechs)
The power and royalty that Sirzechs displayed managed to calm the crowd, the Maou used a bit of Issei's fame to say that everything had been ordered and was under control.
"What a headache." (Sirzechs)
....
....
The Gremory Group was training with all their strength as they thought about facing Sona, Issei participated sometimes to help them, but he was usually busy doing something else that interested him much more.
"You will win, I'm sure of it." (Issei)
"We must not underestimate Sona, she is a very shrewd person and my strongest piece will not participate." (Rias)
Rias still ground her teeth when she remembered that Issei would not participate, her most powerful Rating Game piece was removed just like that.
"I still want to break their legs when I remember it." (Issei)
Issei felt very upset about the punishment and truly wanted revenge, but not now, it would be in the future...
"I'm surprised you controlled yourself, I hope you manage to behave in three days when we go to the Rating Game." (Rias)
"I will behave, a lot." (Issei)
Issei promised to behave with both hands behind his back, he was crossing his fingers while doing so, so he wouldn't be fully committed.
"He's crossing his fingers." (Koneko)
Issei became nervous when the loli noticed it and accused him of that, he needed to turn things around and come up with something.
"I bought some cosplay clothes for myself." (Issei)
Everyone was now surprised by Issei's statement, they wanted to know what that man was planning with those clothes.
"I'll make a bet with you all, the girls will be able to choose one cosplay outfit for me to wear for an entire week, it can be a bunny, a deer, a butler, anything non-vulgar, and the boys will be rewarded with a guys' night if we win." (Issei)
The girls became very excited imagining Issei dressed as a butler or a sexy bunny, they had to win. Kiba and Gasper were even more excited about having a guys' night with Issei.
"We will win!!" (Gremorys)
The group trained with even more enthusiasm while Issei headed somewhere else, he was going to the Gremory house to play with Mililicas.
....
...
...
Issei waited three days and for the time Rias and the others left for the Rating Game to begin his revenge plan against the Maous and the higher-ups.
"Mililicas, let's play Khaos Brigade, your father will also go, but you can't tell him." (Issei)
The red-haired child moved excitedly toward what he and Issei had been planning for days in the Khaos Brigade game.
"What do we start with?" (Mililicas)
"We're going to a TV network that I hired for the game." (Issei)
Mililicas and Issei left happily, the young Hyoudou was disguised with makeup, sunglasses, dyed hair, and other things to conceal himself.
"Let's go, I'm excited to start the Khaos Brigade game." (Mililicas)
Mililicas was very pure when he believed Issei, he thought it was just a game created by the young man when they arrived at the television station.
"Let's start the acting." (Issei)
Mililicas pretended to cry while asking everyone for help, Issei beat everyone with punches and kicks until they invaded a specific set he wanted.
"The Khaos Brigade kidnapped me!!" (Mililicas)
"I have an announcement to make, don't interrupt or the Maou's son will die." (Issei)
Issei and Mililicas managed to infiltrate perfectly with violence and magnificent acting from both, they were laughing when thinking about the trouble.
"The channel will be interrupted, the Khaos Brigade has an announcement to make." (Issei)
Issei kicked the woman presenting the news off-screen and sat in her chair while smiling perversely.
"I have an announcement to make, the Khaos Brigade has just set fire to the houses of some higher-ups, stole Serafall's special Mahou Shoujo collection, wrote that Beelzebub has snot hair in the sky, broke Asmodeus' bed, and kidnapped Sirzechs Lucifer's son." (Issei)
Issei presented proof that he did all of that while pulling Mililicas, who acted by crying and asking his parents for help.
"Help!! Oto-san, Okaa-sama!" (Mililicas)
...
...
Sirzechs was in his office with a very powerful aura, he was furious while Grayfia, with extremely high demonic power, was also glaring murderously at the television.
"The Khaos Brigade has gone too far." (Sirzechs)
"We must make an example out of them." (Grayfia)
The door opened with the other three Maous arriving together with a furious Sairaorg, ready to fight the Khaos Brigade.
"Let's fight." (Beelzebub)
"They will pay." (Astaroth)
"It's time for payback." (Sairaorg)
"Nobody touches my Mahou Shoujo collection." (Serafall)
Everyone had their auras raised while Sirzechs moved to the front, he was ready to destroy everything in his path to save Mililicas.
"Let's go." (Sirzechs)
"Hai." (Everyone)
...
...
Issei and Mililicas were laughing as they left the Underworld television station and were shocked by the scene in front of them.
"What..." (Issei)
"What the hell is this!" (Mililicas)
Mililicas and Issei saw the Underworld on fire, with some pro–Khaos Brigade people attacking, pro–Maou people fighting the enemies, magic and fistfights everywhere.
"Want to pretend this never happened?" (Issei)
Issei was interrupted by a man who stepped in front of him, that man seemed very powerful and emanated a high-class demon aura.
"I'm glad someone is serving the right side, let's go to the headquarters." (Noble)
Issei and Mililicas looked at each other when they thought about causing even more trouble inside the real Khaos Brigade.
...
...
"For the ancient Maous! For the Four Originals!" (Khaos Brigade)
The headquarters they arrived at belonged to the faction of the old Maous, both of them were surprised by that, but even more excited about what they would do there.
"The Khaos Brigade is a serious place, a resistance against the hypocritical Four Maous." (Noble)
Mililicas and Issei listened to what the man said, his ideology, and decided to pretend they were pro–ancient Maous.
"We are willing to serve the cause." (Issei/Mililicas)
"I'm surprised, but happy." (Noble)
Issei and Mililicas thought all of that was really cool and believed they were now playing spies.
...
...
Rias returned exhausted from the Rating Game, Team Gremory managed to win with great difficulty and were almost defeated by Sona.
"What the hell is this!?" (Rias)
Rias and the entire Gremory Group were shocked by the main city of the Underworld being on fire and wanted to know what was happening.
"The Khaos Brigade attacked and took Mililicas." (Sirzechs)
Sirzechs appeared with a serious face beside the Maous, Sairaorg, and Grayfia, all six were extremely angry thinking about the chaos.
"Look at this, they started everything." (Sirzechs)
Sirzechs showed a video of a man wearing sunglasses beside a crying Mililicas, the Gremory Group was shocked when they saw that person.
"That person is Issei!" (Rias)
Sirzechs and the other five were even more surprised when Rias said that, that man looked nothing like Hyoudou, the Gremory Group realized that as well.
"Is he part of the Khaos Brigade?" (Sirzechs)
"No, he probably just wants revenge and used the Khaos Brigade as a shield, but the real Khaos Brigade seems to have intervened." (Rias)
Rias thought her pawn was truly insane when provoked or contradicted.
"Revenge for what?" (Sirzechs)
Sirzechs didn't think what they did to Issei deserved attention, since they were saving him from something much worse, like prison.
"Issei has a very big ego, he protects his own, and retaliates against those who offend him, he can be the best ally, but also the worst enemy when he feels wronged. My pawn felt somewhat wronged when he received that punishment, since he only made some people recognize their own place, he feels entitled to retaliate after receiving that from you. I warned you that this man should not be provoked or you would face serious problems." (Rias)
All six who didn't know Issei well became nervous, they had messed with someone extremely insane and retaliatory.
"Will he hurt my son?" (Grayfia)
Grayfia was very worried about Issei hitting Mililicas as revenge, but she calmed down after analyzing the situation.
"No, Issei is a very fair person and Mililicas is probably being tricked by my pawn into thinking this is a Khaos Brigade vs Maous game." (Rias)
"So we can't punish Issei or an even worse chaos will happen?" (Sirzechs)
Sirzechs felt sulky thinking about punishing Issei, but he didn't want that madman doing something worse afterward.
"He accepts punishment when he recognizes his own mistake, but Issei didn't see this as a mistake, and I believe most people don't either..." (Rias)
Sirzechs and the others finally understood his mentality, the truth was that any punishment, small or big, was irrelevant if he felt it was unjust.
...
...
Issei and Mililicas were training with the Khaos Brigade when both were suddenly teleported somewhere else, confusion hitting them immediately.
"It seems the device I put on Issei worked and brought Mililicas along." (Azazel)
Azazel had placed a device on Issei to capture him due to his troublemaking personality, and it proved effective.
"It's his fault!" (Mililicas)
Mililicas already knew things had gone off the rails when they went to the Khaos Brigade hideout.
"And the cause?" (Issei)
"The cause won't save me from punishment." (Mililicas)
Issei and Mililicas started arguing in front of everyone while those present thought that man could be a genius with the mentality of a selfish child.
"Do you know you went way too far this time?" (Sirzechs)
"A little..." (Issei)
"You set the entire Underworld on fire! The situation is complete chaos!" (Sirzechs)
Sirzechs was usually calm, but this time he needed to properly scold Issei so the young man would acknowledge his mistake.
"Y-Yeah... I overdid it." (Issei)
Issei kept his head down, realizing he had done a lot of shit, even though the real fault was the true Khaos Brigade.
"You have been classified as a danger to the Underworld and will need 24-hour surveillance, Serafall will handle that." (Sirzechs)
Issei didn't want to be watched 24 hours a day, he didn't like girls in his room and he wouldn't like that punishment either.
"You'd better return my Mahou Shoujo collection when we go back." (Serafall)
Serafall was extremely angry while speaking to Issei, she wanted to beat him senseless right now, but held back.
"You and Mililicas will be grounded in your rooms for a while, but before that we need to administer a special punishment for the two troublemakers." (Grayfia)
Grayfia lowered Mililicas' pants and started spanking him while the boy cried, Issei tried to escape through the window but was grabbed by Sirzechs.
"Each of the four Maous will give you 1000 spanks, Grayfia will also give another session of 1000 spanks, and at the end Rias will be there." (Sirzechs)
Issei was terrified when his pants were lowered and the spanking session began, Sirzechs showed no mercy.
"Help!!" (Issei)
"You totally deserved this." (Qin)
"How beautiful." (Akeno)
"You will receive the punishment you deserve for acting like a brat." (Sirzechs)
Issei screamed in pain while everyone felt secondhand embarrassment seeing him in that position.
