MaTachin- He's not kind to Rias Peerage, he just doesn't care about them anymore

BigSmokeYeet- Undertale monsters incoming and I will say that one of those 'OCs' is actually a character from Undertale

Ni and Li charge at Issei and Koneko. Ni kicks Issei but he blocks the strike while Li punches Koneko in the stomach, making her groin in pain. The Neko wraps her tail around the Rook of Rias' waist and throws her through a tree. Issei ducks a dropkick but is then hit in the back by the other sister. "Gah!"

He kneels in pain as Ni and Li punch him and he falls down. "Please stop Ni! Li! I can't hurt you!"

They roar with madness as energy goes into them and their Neko ears and tails are engulfed in blue flames. They speak together. "Kasha Form."

"They are absorbing more chakra than their body can handle. If we don't stop them, their bodies will self-destruct." Koneko steps beside Issei with cat ears and tail on her. "You are right Issei, I hid from my past and wanted to forget it. But I am Shirone and I must help my Neko sisters. If you want to free them from their frenzy funk, you gotta hold them off while I absorb their energy."

"Right." Issei agrees and takes on his pawn twins. He blocks a punch from Ni but Li hits him on the back of his shin, forcing him to kneel. Ni whips Issei with her tail but he grabs it, making her moan. "Whoa! What the-"

"A Neko's tail is our weak spot!" Shirone said as she feels the chakra absorbs into her body, making sure she doesn't go insane. The Boosted Gear user has an idea and grabs Li by the tail and she shivers in delight. The Neko twins kneel beside Issei with blushes on their faces.

"Hurry Shirone!" He shouts as they are starting to get their bearings. Ni and Li pass out and Issei holds them in his arms. He turns and sees Shirone's cat features getting more pronounced. She opens her eyes to show vertical silts and roar at him. She runs at him but is suddenly hit in the back of the head, collapsing unconsciously. The savior is a dark-hair Neko woman in a kimono. "Good, I made it in time, Nya."

"Who are you?" Issei asks as he holds Ni and Li protectively. The stranger picks up Shirone and holds her wedding style. Issei can't help but notice she's holding her affectionately and smiles.

"Nice to meet you, I am Kuroka. Thank you for looking after my sister, Nya. Could you tell those two I am sorry? I hope they will understand someday." Issei watches this Kuroka walk away with Shirone in her arms. Ni and Li wake up with a migraine in both of their heads.

"Master Issei?"

"What happened?"

He looks at them and hugs them. "We won. I'll explain on the way home."

"You lost Excalibur?!" Valper shouts at Freed as said Stray Exorcist is holding his stubbed arm. "Lay off me motherfucker!"

"Our weapon to dismantle our Devil enemies is gone thanks to you!" The ex-priest yells with his face turning red with rage. The door opens which makes Valper pale and scared as Kokabiel and two others enter the room.

The one to his right is a woman in blond pigtails hidden by a cowboy hat, yellow hoodie and shredded jeans. Her left eye is a bright silver-red and if you look closer, you can see it is glowing. On her side is a pistol holster with a revolver inside it.

The one to his left is a yellow female reptilian monster with round glasses and white lab coat.

"So you failed to bring Excalibur." The Fallen Angel said rather calmly. But Valper can hear the steel voice that blames him for this failure.

"M-my lord! I assure you that this failure is the result of this mistake's actions." He points at Freed, who is trying to block his bleeding stub. "I promise you this milord that I can reclaim Excalibur. Your weapon to destroy the Underworld will be found."

"I don't care anymore. I have found something or rather someone that will destroy the Underworld. I give you Roxie, the Left Eye of Lilith. She is a woman of justice that has taken out entire legions of supernatural beings."

"Oh course my lord. I introduce you to her." Valper tries to show his importance but Kokabiel fires a ray of light which disintegrates the ex-priest. Freed can't believe that he was killed without thought. Roxie walks behind Freed Sellzen.

"I wasn't talking to you." Kokabiel said and points to the nerdy monster. "This is Alphys, my personal scientist and creator of original monsters. The creatures she creates are the army that will make the new war so much fun. Alphys, are they ready?"

She nods and adjusts her glasses. "Y-yes milord. The Amalgamations are ready for deployment."

"Yes…" Kokabiel smiles at the news and snaps his fingers. "Sadly Freed Sellzen, I don't require you or Valper Galilei's services anymore."

Roxie aims her revolver on the back of his head and pulls the trigger.

*BANG*

Issei's peerage sits in the home of Kure Erioh with the clan head and Asia Argento, who decided to stay in the village to get away from Rias' wrath. Since then, she has become the village medic. "Good to see you are all safe."

"Thank you Erioh-sama. However, we need to find out who killed Aika Kiryuu." Ravel said but Siris is confused.

"What do you mean Lady Phenex? It is clearly Red Son and Freed." However Ravel disagrees with that statement. "I'm afraid that is not the case. Red Son was sighted in India, killing monsters when the murder happen and though Freed is a option, Aika's corpse would've been more defiled. What is odd is how she died. Her heart was ripped out as if someone grabbed her chest with their bare hands."

Issei enters with Ni and Li. Ravel notices him and hugs him. "Good to see you are okay. Unfortunately we still don't know who killed him. But we did stop some freaks from causing damage around the city."

"That's okay, we will find out someday. For now let's talk about Erioh-sama, you said you had the DNA test results." Issei said and Erioh nodded and he pulls out a file. He takes out the results and reads it.

"I'm afraid Issei that you don't have any Kure genes." He reveals which shocked everyone, especially Issei. He points at his black sclera and whitened irises: The eyes of a Kure.

"How do you explain my eyes?"

"That is the mystery. You are 100% human and don't have any Kure blood. This is a theory but you may be-"

A Kure servant comes out looking exhausted. "Lord Erioh! Kokabiel is attacking Kuoh with an army of monsters!"

"We will finish this conversation later. For now you need to go and stop the mad Fallen."

Issei nods as he and his peerage are about to teleport until someone opens the door quickly to show Kure Karla with a big grin. "Don't think you can leave me! I'm coming too."

"Karla what are you thinking?" Erioh questions and she answers with a smile still on her.

"My fiance is going to battle so of course I gotta be there by his side." She latches onto Issei and you can feel the jealousy emitting from everyone. Issei sighs and he readies his Boosted Gear.

"Let's get some answers. He may know about Aika's murder. Welcome to the team Karla."

Next Time- Invasion of Kuoh
