High School DxD: Chaotic Destruction

"You do know that by me simply existing, this world might be destroyed?" Lucifer asked while looking around the dimensional gap, which was way too small for someone of his level. Just existing, this verse felt like a water bottle holding far more water than it should possibly be able to hold, causing it to feel as if it would explode. Lucifer had to Will himself to be far weaker than he was, this way nothing bad happened.

"Through Destruction can this verse be recreated stronger than ever? So, as you slowly break it apart, I will put it back together, strengthening this verse to heights never seen before." I said lightly. I floated off Great Red, which the 3 followed.

Great Red stayed in his dimensional gap, wanting to enjoy the new improvement he got to his power. So, we flew through a portal and appeared inside my house, where I found my mother sitting before her laptop, a lost look in her eyes.

"What's wrong?" I asked, causing Asiya to jump lightly since she hadn't noticed my arrival. She looked over and was caught off guard by the three following behind me.

"You made new friends?" Asiya asked in shock, to which I rolled my eyes.

"This is Irene, she has greater potential in enchantment magic than me. This is August, he could copy and nullify any spell he sees, and this is Lucifer Morningstar, the devil." I said calmly.

"Lucifer?" Asiya's eyes widened, for the original devil, was Lucifer.

"Not that Lucifer, go on your laptop and look up Lucifer Morningstar DC, you should see him," I said with a smile, Asiya was confused, and so were Irene and August. But when Asiya searched Lucifer's name, and an American comic popped up, they were stunned.

"T-this..." Asiya didn't know how to react, I mean how would you react if your son came back with a comic book character?

"Where is Rias?" I asked lightly, seeing as Rias wasn't in the house. Asiya flinched a little at that, causing me to look at her waiting for her to explain.

"... You're her twin brother. the one she thought died." Asiya said causing me to pause for a second. I couldn't help but blink, the concept of impregnating my sister being... well, something I needed a second to comprehend.

"Well..." I said lightly before teleporting away, appearing before Rias who was on the beach, looking at the setting sun, with a lost look. Rias seeing me pop up, could only lower her head. To that, I sat next to her.

"So, we are siblings," I said lightly, to which she nodded lightly, unable to look up.

"But... I refuse to think everything I felt was simply some bloodline connection or something like that." I said, but this caused Rias to start crying.

"I don't want to give birth to a monster." She cried. Like humans, devils who give birth to an incest baby would pay a huge price. Thanks to the Devil's bloodlines carrying powers tied to their bloodlines, if genetic defects appear... well, it shall lead to the birth of a monster with the mind to destroy all in its path.

"I already fixed that," I said lightly, shocking Rias.

"I wanted our child to be powerful, so when I found out she was pregnant, I created a spell to strengthen, purify, and perfect her bloodline. I checked to ensure this wouldn't have negative side effects on her. What truly matters is her source, and it's clean." I said lightly while looking at my soon-to-be daughter's source... the source of destruction, 

Devils are beings that originated from the Underworld created by the Original Lucifer using the body of his wife Lilith to create a military force to destroy God and his Angels, as well as to realize his ambition for world domination which consists of the High-Class Devil nobles of the 72 Pillars and Extra Demons and the countless armies of Middle and Low-Class Devil soldiers under them.

"..." Rias sighed in relief, rubbing her stomach with a happy smile. The idea that she would have to kill her child was eating her alive, she was so happy when she found out she was pregnant until she was hit with the fact she needed to kill her child.

"Wait! it's a girl?" Rias asked to which I nodded. Rias jumped in joy, she would of course want a daughter more than anything else. I said nothing, simply watching her with a faint smile... but after a moment, Rias calmed down.

"W-what about us? I don't want to think what we had was all a misunderstanding... I truly loved you." Rias said to which I got up and took her hands,

"Then let's destroy it? I can destroy the fact we're related." I said stunning Rias, but she nodded without thinking... and with that the bond between sister and brother was destroyed, and Rias felt it.

"How do you even destroy that?" Rais asked speechless by my power, but she just hugged me as she no longer had any reason to doubt this... even if we still were related, she would have still pushed to be with me. Even if the love we felt at first was false, we were both sure what we have now was true...

"It doesn't have to be real. It can be fake... I just want to see you smile for me once..." A shy uneasy voice sounded, causing my eyes to pop open. I lay in bed, looking at the ceiling for some time, before looking over towards Rias who was fast asleep, hugging me tightly.

After two days of traveling, all without sleep, and on top of that crafting my sword... well, I was tired. Like Anos, I two needed sleep. I needed my rest. I got out of her hold, leaving her to get her rest. I went downstairs and found August and Irene working together on breaking down the magic system of not only this world but also the DC world.

Lucifer had gone off on his own, Lucifer had instantly understood this world's magic along with everything else, he instead gave his magical knowledge of the DC world to the two before leaving.

I left the two alone and shot into the sky, calling for Lucifer as I might need the guy's help in the battle that was about to come. I could feel it, that being was here, and it was locked onto me, killing intent fueled with hatred that was like nothing I have ever sensed...

In the Absolute void, holding all verses, one would find a white-haired woman shooting through this void. She had no protection or means to defend herself from this void, even so, she wasn't being affected. Instead, as the void power tried to affect her, its power just stopped existing. It was like she was at the end, the walking Conclusion for all that exists.

"I'm finally here," She said with a bloodthirsty smirk seeing the verse known as High School DxD up ahead. She grinned, shooting forward at extreme speeds... no this wasn't extreme speeds. This was a speed that couldn't be put into words, for it transcended common sense.

This is speed which in a place of space and time, would allow her to reach point B before she left point A. This was speed that allowed her to run so fast, that she could run around a whole planet and stretch her back. This was a speed that could allow one to move so fast, that they could warp reality. This was a speed so fast, she could step forward and turn around so fast she could hug herself... this is the speed of a being almost Boundless.
