Issei woke up in an abandoned construction site in the middle of nowhere. He could see the sky through the roof, which was never built. It took him a few moments, and then he suddenly remembered everything that has happened. Ignoring the building, only the rough framework of which was built, he frantically tried to stand.

But...

"Do not worry; I will heal your injuries." Someone replied from the side.

He turned to look at the speaker and found: Himself.

"What is this? Who are you?"

He asked the Issei that looked just like him. No, not just like him, there is a air about him that he currently no longer has.

"I am also Issei. But I am from another world. "

"What? Another world? What do you mean?"

"I came from an alternate timeline. My parents are alive, and so are my friends, so from what I understand, I didn't undergo the drastic change in personality that you did. And I don't have a sacred gear that is identical to yours."

"What, Oka-san is still alive? Issei inquired, momentarily distracted from discovering the doppelgänger's identity.

"Yes. But in my dimension." He replied somewhat solemnly.

"I see. Typical. No such luck for me."

Issei stopped talking as his wounds continued to heal; then started to notice that his stamina wasn't returning.

"What is happening? My injuries are disappearing, but…."

"Hmm. I don't know, really. I just got this sacred gear." Issei from another world replied.

"Wait, what do you mean, this one is not yours? You just said we possess different sacred gears, right?"

"Yes. But I got this one a while ago from a fallen angel. They escaped, but I managed to get the sacred gear."

"What is your real sacred gear?" Issei asked suspiciously.

"It is the ability to rip apart sacred gear from other users and ….."

But before he could finish the sentence, however, Issei finished it.

"And evolve them to become stronger?"

"Yes. Wait, how did you know that? Don't you have the boosted gear?" Isekai Issei asked.

"Yes, but I got that from a guy. It wasn't originally mine. He was a fallen angel scientist. Where did you get it?" Issei remembered the scientist who promised him vast power.

"I always had it." Isekai Issei replied, looking somewhat confused.

"Then, how did you get to this world? I thought your sacred gear might allow travel between alternate dimensions. ….." Issei trailed off.

"No actually, that power comes from another sacred gear I stole." Issei declared proudly.

"I wonder if it is the exact duplicate of mine," Issei muttered, but then he trailed off as Isekai Issei fiddled with a phone he recognized.

"Hey, that is mine. Private stuff. How will you do get that to open? Another sacred gear? Actually, how many do you have?"

"Ah, allow me to show you the ultimate sacred gear. Let me tell you, the God from the Bible was amazing. To think he created something this awesome."

This other him was tiring to deal with. More importantly, he just heard something absurd. Though he did acknowledge that he would have liked this sacred gear a few years back when he was still an ordinary high school student.

"So what does this do?" He asked, dreading the answer. Interacting with his other self was bringing back some of his old personality. He didn't like it; not one bit.

"Well, it can do a bunch of things. First I can rewrite any aspect of anything, but only if they are what I can understand. I can write my own story and bring them to life. Basically, I am a writer. And what I write becomes real."

"And let me get to the best part. I can perfectly create a new type of existence. I can create something just like the original."

"You mean you can clone something?" Issei asked his other self. That could be useful. He could create an army.

"No no, it is nothing like that. A clone I can create, but this is better. I can create an existence just as genuine as the original. The new instance and the original are both the real thing. It is reality manipulation." Issei boasted the power of his awesome sacred gear that the God of the Bible supposedly made.

"What terrifying ability." Issei thought, a new existence indeed. Both are original, with no difference.

"A tool created by the capital G God, indeed." Isekai Issei praised the God of the Bible who created such a marvelous device that answers to his ultimate dream. Why wouldn't people worship him?

"I see. You are right. So, does it have any other ability?" Issei was now getting interested; he was a former otaku after all.

"Yes, it can also summon anything I want."

"Can you bring out a time machine? Issei asked. If he could do that, then maybe he could go back in time and prevent the death of his parents. …..

"This sacred gear allows me to do anything as long as I train. I think it contains all the powers of the God in crystallized form. As I said, anything is possible. Not right now, though. I am a little tired. Also, never done it before. Maybe tomorrow?" Isekai Issei offered.

"Yeah, that would be welcome. But he put all of his powers in there? This is a truly outrageous ability." Issei didn't know what else to say.

"I will leave this version of Akeno from my universe. She can help you in the future. I saw something interesting earlier, so I will go check it out.

AN: The chapter is considerably lighter than the others. I figured some breathing room was necessary. Also, this Isekai Issei is just like canon Issei. I figured if I am to write a DXD fanfic, I might as well go all out. His power is that can do basically anything he wants, but he has only trained to be the Otaku King. The noblest goal. He is overpowered because one can't have fun if you do not know you are safe. Take a look at the Isekai protagonists and how overpowered they are.

Unlimited Budget Works is something I saw in a thread. I can no longer find it. It isn't my phrase. Do not sure.

Next chapter, Akeno, and Issei.
