Ultimate Highschool DxD

As everyone began taking their preparations. Isaiah (Kiba) and Xenivia sparred with each other a bit. Gasper was on the other hand trying to comprehend more of his vampiric powers alongside Asia who is also training her [Twilight Healing]. Akeno spars against Tsubaki, trying to further increase their experience. Rossweisse is currently having a talk with Issei, Sona and Riad. In any battle, strength is never the deciding factor. And that's a fact.

The deciding factor of any battle is the strategy. Swinging your weapons like buffoons and attacking with magic like idiots and fighting like maniacs an never help one win a battle. It's the intellect that matters otherwise armies wouldn't have commanders leading them.

The three girls kept on giving different strategies while Issei listened carefully and kept rejecting each of them. A God is a being that can defy the laws of the universe quite easily. A fight against a God like Loki in the conventional way isn't gonna do any good. Cause Loki will definitely not be alone. Issei already knows that Loki will have various monsters and Fenrir alongside him. The plans that were being given were solely focused on Loki. It seems they didn't give a single thought if Loki would have any subordinates. Finally getting agaitated hearing the same kind of plans over and over again, he spoke.

"Even though your plans are good. All of you are forgetting something."

"""What did we miss?""" asks all three of them.

"Rias, what is the purpose of Loki's actions?"

"It's Ragnarök."

"Sona, what is Ragnarök?"

"Ragnarök meaning fate of the Gods, is the battle at the end of the world in Norse Mythology."

"Rossweisse, tell me what are the prophecies regarding Ragnarök?"

"It is to be fought between the Gods led by Odin; and the fire giants, the Jötnar and other monsters, led by Loki and Surtr."

"Correct! Now suppose we remove Surtr and the fire giants alongside Odin and the Gods from the equation. Then we only have Loki and his monster. Do you know the name of the monster who will stand beside Loki."

"Fenrir." said Rossweisse. The moment she muttered that name it felt as if she was enlightened. Rias and Sona also seemed to understand the situation.

"Now do you get it? We need to think about Fenrir as well if we want to defeat Loki."

"But that won't be easy, Fenrir is after all Loki's strongest son. He is also one of the top ten strongest beings in the world. He is a wolf that even the Gods are afraid of." said Rossweisse.

"Leave Fenrir and Loki to me. I already have plans prepared to dealing with them. I want all of you to deal with the little Fenrirs, weaker versions of Fenrirs cause there's gonna be a lot of them. I'll tell you how everything else later on the battlefield. Now, all three of you should take a rest along with everyone else."

The three girls nodded at Issei as they got up and along with he others they went to have some rest. They don't only need to have to be in a good physical shape, but they also need to have a calm mind and fast thinking if they want to avid any casualties. Issei also got up and went to his pocket dimension. He wanted to have a talk with Shirone and Kuroka.

"Shirone, Kuroka we'll all be going up against Loki and Fenrir. Do you two want to join as well?"

"Yes, I want to fight alongside you and the others." said Koneko.

"Yes, I would also like to fight against Fenrir. I am a part of Vali's team, so now that I'm on your side I need to inform them about it." said Kuroka.

"Alright. Let's go." Issei then exited his pocket dimension with Kuroka and Shirone. He decided to introduce Kuroka to everyone and prove her innocence. He first teleported to Sirzechs's chamber along with Kuroka and Shirone at his side. Sirzechs was just sitting on his desk going through various paperwork.

"Good evening, Sirzechs. I need to have a talk with you."

"Good evening, Issei. What happened?" After he said that, Sirzechs looked at Issei and noticed Shirone and black haired Nekomata beside him. He could sense that the aura emitted from the black haired Nekomata was that of a Nekoshou and a devil. Immediately Sirzechs stood up and he got on alert. Even though he never met her, from the information about her he knew that this Nekoshou was definitely Shirone's older sister, Kuroka. Kuroka was among me of the most dangerous criminals of the Underworld, ranking SS-class. She is known to be a stray devil, who killed her own master being drunk on power. Sirzechs knew all of this very well, after all he was the one who took in Shirone after Kuroka left her and handed her to Rias. What we this Kuroka doing here?!

"Calm down, Sirzechs. I'll tell you everything." Issei then gave an explanation regarding Kuroka and Shirone's lives along with their backgrounds and all the unfortunate events they both had to go through at an early age. He explained that Kuroka was never drunk on power and she killed her master for the sole purpose of protecting her sister. When Sirzechs learned of the truth, he was disheartened. He always knew that various criminal activities wee going on behind the backs of the Satans, but he never thought that even after being such a serious crime that the punishment for it is a death sentence, devils would still dare to experiment on the Nekoshous. Because of his lack of awareness, these two sisters had to go though such hard times and Kuroka was even declared a criminal for committing no crimes at all.

"I'm very sorry, Kuroka and Shirone. Because of my lack of farsightedness you both had a very sad past and Kuroka was even declared a criminal. Issei, if you could just provide me with some proof I can prove Kuroka's innocence to the entire Underworld and give punishment to the House of Naberius."

Issei then gave Sirzechs the files regarding the experiments that were done on Kuroka and we're supposed to happen to Shirone. Sirzechs immediately called the other Satans and informed them of the matter. With the cooperation of all four Satans Kuroka's innocence was proved to the entire Underworld. The House of Naberius was stripped of their title of Marquis and we're reduced to the title of Count. The members who were associated with the experiments including the Lord of the House were publicly executed. Issei then introduced Kuroka to all his friends and acquaintances .Issei then went to his room to change his clothes and get ready for the upcoming battle against Loki and Fenrir.

But then something unexpected happened. It felt as if time itself had stopped. No!! Time really had stopped and not just this room or the Underworld, but all of time, all of existence came to a stop! Issei was the only person in existence who was now able to move! This power seemed very similar to the Longinus Aeon Balor, but how could it work at such a cosmic scale!

Suddenly black miasma surrounded the room as a figure appeared in front of Issei. The figure's entirely body was covered in black miasma. But two things were noticeable. The figure seemed to have long jet black hair that seemed even darker than the void of outer space and there were two bloody crimson lights on it's face, which were probably it's eyes. Just one look at this being could literally make someone's body shake in fear and despair. No! Not fear, it's terror! But for some unknown reason or didn't seem to affect Issei much, as he managed to maintain his composure. Isseianaged to stop the shaking in his body and he managed to ignore the danger Donald his instincts were giving as he asked.

"Who are you?" When Issei asked that question the figure started speaking in a demonic voice that would make anyone soil their pants but at the same time induce respect in their soul. The voice sounded beautiful, almost like a music. The voice was masculine, so Issei understood that this mysterious person was a man.

"This King is someone who is above all. Who is truly immortal and who is Supreme." said the mysterious man.

"Why are you here?"

"We came here to speak only one thing."

[A/N: Here 'we' refers to the mysterious person. During ancient times the Kings and Queens referred to themselves as 'we' instead of 'I' to show their might and supremacy]

"Remember the time is near. No one can escape their destiny. Neither can you. The wheels of fate will collide to open the door to the end."

"What do you mean by..." Before Issei could finish his words the mysterious man kept muttering what he said previously and disappeared. Everything returned to normal and the flow of time started again. Issei was baffled from the event. He couldn't make sense of anything the mysterious man said, but he understood one thing. Whatever's gonna happen won't be good.

Issei put the whole matter in the back of his mind for another time. Now is not the time to be thinking about it, after all there is a God that he needs to defeat now. Issei exited the room and went to meet up with everyone. The time has come for the defeat of a God!
