[Issei's POV]:

Man, three days after that brutal training with Kenji but not gonna lie I feel very different. I remember what Ddraig said.

*Flashback*

Ddraig: "Issei, I feel something very strange after that training with Mister Kaslana."

Issei: "Strange? After that training with him I could barely move my body."

Ddraig: "Yes and... You deserve that for the past. But, after that training I feel great power in me."

Issei: "Great power? How do you feel that kind of power if I didn't hit him?"

Ddraig: "I don't know but if you continue to train with him we might be even stronger."

*Current Time*

[3RD POV]:

Rias: "Issei, did you listen?" Issei snap back into reality and looked at Bachou

Issei: "Huh? Um... Can you repeat that?" She nodded her head as she turn to my attention.

Rias: "As what I was saying-" She was interrupted by Riser and his peerage entering the Occult Research Club as some of them was surprise to see him but as for Rias she had a serious look on her face.

Riser: "Ah! Riser was been reborn!" Riser shouted as Issei summoning his Boosted Gear as he saw Riser wave his hands around to him.

Riser: "Calm down! Calm down! Riser is not here to fight... Riser is actually inviting you all to see Sirzechs and Mr. Kaslana fight." All of them were shock to hear that.

Rias: "WHAT?! My brother wouldn't accept a challenge like that against his former student!"

Issei: "Yeah and after training with him I doubt that he's gonna waste his own time fighting him, no offense."

Riser: "Well... Sirzechs and Riser didn't tell him yet but he's planning on taking all of you with him to St. Tawagama to the boy."

Kiba: "That's surprising that your changing after last time..." Suddenly Riser's face had changed like he was scared.

Riser: "You guys didn't hear this from me but... Mr. - Lord Kenji, Riser wouldn't get on his bad side cause if so he will kill you or... He could make you disappear."

Irina: "Disappear? Like send you to another place?" Riser shook his head."

Riser: "No, he could make you not exist all together. Riser wouldn't make him upset... WELL it is Riser time to head out!" Riser and his peerage left making them have some thoughts until Kiba spoke up.

Kiba: "Can't say that I'm afraid what will happen if Kenji accepts Riser invitation."

Issei: "No shit! Kenji would kill Sirzechs if he DOES accept this challenge. Crap! Regretting bullying him in the past!"

Rias: "For now on, we should be more careful around him including his friends. Like who knows how powerful they are."

Akeno: "Do you think you will get him in the peerage?" Everyone eyes went to Rias as she was quiet until she shook her head.

Rias: "I don't think it's a good idea. He might think that that's a stupid question and who knows what he's going to do. I don't even want him to accept that challenge and kill my brother."

Xenovia: "How about we go look for him and ask him ourselves?"

Rias: "Yeah. I doubt that Kenji will speak with Riser or my brother. Oh right! Let's go!"

[3rd POV]:

Kenji was walking at downtown while holding a bag until there was a unfamiliar woman that Kenji never seen. She was holding another person with handcuffs and put him in the back of the police car.

???: "This is what you get for trying to rob a store! It's like I say "Do the crime, you do the time!" The female police said. The female police has very long, slender, muscular legs and short, blonde hair and have brown eyes.

Kenji: "Another person, huh?" The blond female officer turned around and smiled while using her leg to close the car door.

???: "Sadly but gladly, have to protect everyone here after all Mr. Kaslana." Kenji smiled and sigh.

Kenji: "Just Kenji, what's your name?" The woman point at her police badge.

Lucia: "The name is Lucia! I'll be working at the Saint Tawagama's Metro Station for awhile so you'll be seeing me either there or here!" She said as she sat down on the edge of the police car with the both of her hands on top of her head while looking at him.

Kenji: "I'll keep that in mind!" Lucia back at the car and gets up.

Lucia: "Well I'll have to get this one back in the station for the SECOND TIME!" Lucia shouted hoping that the person in the back of the car had heard it and look back at Kenji.

Lucia: "Like I said, catch me in the station if you want to talk or... have some coffee." He nod his head and she walks over to the car and open the door as Kenji walks away as she watches him leave.

Lucia: "I gotten say, he's a looker in person." She shook her head and got in the car and drove away.

As for Kenji, he heard his name being called as he turned around to see Rias and her peerage and all he did is sighed.

Rias: "Thank god, we caught up to you." Rias said while trying to catch her breath as for Kenji who put his hand inside his pocket.

Irina: "We're not here to fight but wanted to ask if Sirzechs or Riser asked you about a invitation?" He got confused of what she just said.

Kenji: "Invitation? What invitation?" All of them sighed in relief as Rias example everything to him.

Kenji: "I see, then no I don't accept the invitation." Kenji said while all of them sigh in relief for the second time.

???: "What is this about a invitation?" They all turned around to see a young lady with white hair and blue eyes while she was wearing a short dress while wearing a black coat as they could see some small black wings behind her.

Kenji: "Sup Dai, what bring you here?" Kenji asked the young lady as the devils could literally feel a powerful aura coming from the young lady.

Dai: "Ah yes, I was just on my way towards to see you and your team but I overheard you talking about a invitation. So start talking you fool!" Dai demend him and he sighed.

Kenji: "It's nothing these people- I mean devils give me a invitation to face her brother in underworld." Rias and her peerage was shock that he just called them devils out of the blue.

Rias: "Hey, umm.. We're not-"

Dai: "Underworld? I haven't went there ever since I was a little girl. To think that you expose them to becoming a devils since they are not bothering to controlling that a little aura of theirs." Dai joked.

Rias: "Little aura?! I have you-" Rias went silent when Dai put her finger on her lips shutting her right up.

Dai: "Shh... Your conversation with him has finish now how about you kids go back to your trash school call Union Academy."

Kiba: "T-Trash?!"

Rias: "Our school isn't trash! We have top powerful students at our school!" That for sure, caught Dai's  attention.

Dai: "Powerful? Would you mind showing me this "powerful" students that you speak of?"

Bakugo: "That will be me, you goddamn extra!" Bakugo, out of nowhere said while shooting a bunch of cannon towards Dai as she just stood there. As the smoke cleared up Bakugo and Rias and her peerage saw a blue huge barrier protecting Dai and the innocent peoples behind him.

Kenji: "Are you stupid? Well don't have to answer that actually... Are you seriously trying to attack her AND the people behind us?!" All Bakugo could hear was all the people whispering to each other.

???: "That boy was trying to kill those people! Is he out of his way to use his powers here?!!"

???: "That hot-headed brat! Did he really trying to kill people at Saint Tawagama?! Where is his parents?!"

???: "That brat is gonna get what he deserves from Mr. Kaslana and the queen in The Night of Kingdom Ms. Amaya!"

???: "As expected from Mr. Kaslana! He keeps his promise about saving his people❤️!"

Hiroshi: "We heard a explosion, what happ- Oh..." They turned to Kenji's friends who were flowing in place as they saw the Union students.

Estuko: "What are you guys doing here?" Estuko asked them but Bakugo was going to talk until one of the innocent people spoke.

???: "That brat right there was trying to kill Ms. Amaya and those people until Mr. Kaslana saved them." The man point at Bakugo.

Kieru: "I see... Hey idiot! Explain yourself right now!!" Kieru summoned four spear very close to Bakugo's neck.

Bakugo: "Me? ME?! How about you tell that extra right there!" He pointed at Dai who just looked at him with a serious face until her face changed into a smirk.

Dai: "Oh my! Me? Noooo! How about you let the people behind us tell her what exactly you were trying to do." Bakugo's eyes went wide as he gotten more angry about what she said as the people behind them explain what happened.

Kieru: "I see... Well!" She summoned a handcuffs that was on Bakugo's arm covering his entire hands not allowing him to use his quirk. "You will be at the Saint Tawagama's Metro Station until Union Academy headmasters come and get you!!" Kieru and Fuji grabbed Bakugo's arms as they flew off.

Rias: "That happened..."

Xenovia: "That idiot deserve to be locked up for that..."

Dai: "No, people like that deserve to be locked up BUT for your request... I'll accept you challenge but I'll have Ms. Kieru as my teammate."

Kiba: "Kieru? She probably busy with-"

Kieru: "I can accept that." That made the devils flinch from her already back after what just happened.

Rias: "That's quick!"

Kieru: "There's no need for talk, let's go somewhere away from the people." They all nodded their heads.

[Later that day]:

When all of them arrive to an abandon island as Kenji and the three of his teammates was on the sideline watching as Rias was with Dai and Kieru.

Dai: "Say devil, who are you gonna sacrifice?" Dai said with a evil smirk as Rias smiled and turned around.

Rias: "Issei and Kiba!" Issei grinned at the two ladies knowing what plan he's having.

Issei: ("Man look at those big melon those two have! I kinda wanna see what's behind those clothes!")

Dai: "I see... A very interesting choice indeed. but I may have to put this dog in his rightful place if he continue to look at our breast."

Kiba: "Don't worry about him, he's trying to change but can't." Issei just looked at Kiba but got ready.

Rias: "We don't have no more time to talk, let's get over with!" Rias and the others went to the sideline as both Kieru and Dai including Kiba and Issei.

Dai: "Now! Let's begin!" Dai summoned her scythe on as Kieru summoned her spear while her eyes starts glowing red.

Kieru: "Now enough talking, I'm ready for a fight." Kieru ran towards Kiba with his sword as they clash her weapon together and with Dai and Issei.

Issei became Boosted Gear: Scale Mail  fired off a beam of concentrated demonic power at Dai as she just stood there as the smoke cleared up she was still standing there with no bruise but her clothes was half ripped up. Issei noticed that she was smiling as she looked at her hands.

Dai: "Hmmm... This pain is what I live for. Let see if you could survive this attack!"

Dai transformed her scythe into a spear then rushed towards as he was trying to dodge her attack but ended up getting brutally hit and then hit it in the chin sent him flying in the air but she wasn't done. She release a bunch of raw power to her spear and then threw her spear towards Issei. 

Issei: "GRRAAHH!!" Issei screamed in pain as he fell down onto the ground breaking his entire armor shocking the devils except for Kiba.

Akeno: "No way! It's only been 3 minutes and Issei is already down!"

Asia: "Yeah! Issei only used one attack but that didn't do anything to her!!"

Issei: "I-I-I'm not done! UGH!" Issei got interrupted by Dai stepping her foot on his chest with her high-heels. 

Dai: "Now devil! Is that all you got for me? What a shame indeed and I was just started to have fun too!" Dai said not knowing that Issei just got himself a free look of her black undergarment. Dai finally noticed that and picked him and by his face and threw up.

Ddraig: "Issei! You most use Cardinal Crimson Promotion! That's the only way the defeat her!" 

Issei: "Right!" 

BOOST! 

With that Issei transformed into the Juggernaut Drive and Dai begin to feel the power coming from Issei.

Dai: *chuckled* *lick lips* "Now this is what I been waiting fo- AH!!" She couldn't finish her sentence as she was met with a punch in the face from Issei causing her to crash in the rocks.

Dai: "OW!! OH That's painful!" Dai got up which she saw that her undergarment was showing but not all gladly. 

Issei: "I'm very sorry beautiful lady but I'll have to finish this battle!" Issei rushed to her with full godlike speed and Dai saw two cannons hidden in Issei's wings and fired a powerful beam to Dai which cause her to be in shock.

Rias: "There! It seems that it's over for that little demon!" Rias smiled and the looked towards at Kenji and his friends to see them looking at where Dai got hit from Issei's beam with a serious look on their faces not saying a word and she looked over there to see Dai getting up and her body was covered in blood.

Issei: "I thought I killed you, thankfully I didn-" 

Dai: "Shut up." Issei was surprise by that as she looked at him with red eyes as she transformed into her awakening. "Now it's time for I, Dai Amaya, TO FINISH THIS!!" 

Issei: "W-What the hell is this feeling that I have?! I can't even move my body!" Suddenly Issei saw a sword handle on her chest as she has purple raw power energy around her and she slowly pull the sword out of her chest.

Dai: "May the eternity destroy every confident that you hold dear boy..."
