Esper Harem in the Apocalypse

"Goodbye… brother."

CLAP!

Asura clapped his first two hands and uttered, "Domain… expansion."

The next moment, Rudy's entire body became larger than billions of universes combined— and Asura was covered in a space dimension created by Asura.

It was similar to his space ball, but this time, Asura was also present inside.

CLAP!

Asura clapped again with the other two hands and uttered, "Domain… evolution."

Another layer of space dimension covered the first space dimension, forming zig-zag pattern rings around it. It seemed like a thorned cage surrounding the space domain.

CLAP!

Once again, Asura clapped his last two hands and uttered, "Ultimate… absolute… domain expansion."

The moment Asura uttered that, the zig-zag pattern rings' cage began coming like a mechanical machine. And each zig and zag created a tree— whose truck was made from light and space, and the crown, including the branches and leaves, were made from stars and galaxies.

There were millions of zig-zag patterns, and each of them created the galaxy tree, covering the space domain completely.

With three continuous domain techniques, Asura had created what one could call a… universe. And it was bigger than any universe to ever exist.

"This is my strongest and the ultimate move. I have never ever used all three at once. And even when I used them, it was to destroy and create the second reality again.

With this… I trapped you and me both in this… universe. You can't get any stronger or bigger now because you have nothing to eat. This universe is hollow from the inside. We are the core of this universe. And we will stay here for eternity.

However, you are a void. This universe will feed on your power to expand even further and slowly devour you. Ultimately, you will cease to exist while I will be free."

He glanced around and said, "Being trapped here for eons is just a small price to pay to obtain what I want. I have lived eons of eons of years, so this is nothing in comparison. I know patience. "

Rudy also spread his hands and clapped.
"Domain… existence."

"...!"

Asura watched as the space inside the space ball dimension began to disappear as the light spread rapidly. And before he could do anything, the entire universe created by Asura had become nonexistent.

Rudy's powers were based on his imagination. If he thought of something, it would come into existence. That power was… the power of creation. But he needed something to trigger that power, and that was his faith, belief, and logic behind it.

If Rudy truly believed in something— even if it seemed illogical to others— if he had faith in his power, it would happen. However, there were many easy ways to trigger the power of creation.

If a certain power or ability already existed, Rudy had no need to find the logic behind it because he knew such ability could exist. He could copy the same ability effortlessly.

Asura also had a somewhat similar power where he could copy and steal the power of the ones he defeated.

When Asura used his domain techniques, Rudy didn't have to try to find logic or fundamental principles of the technique, he simply needed to use it.

"Impossible…" Asura dropped to his knees and mumbled, "How did you do that? Domain techniques are my original moves. No one should be able to do them. Yet… you enhanced and evolved all my domain techniques and created your own version of it.

That was my strongest attack, and if it had no effect on you… then I have… lost."

When Rudy used his own version of the domain technique, he created not one, not two, but millions of universes.

"You seem to misunderstand something… Asura."

"What?" he asked without looking at Rudy.

"You indeed have the power of space, and the first reality could have the power of time. However, I don't have the power of the void."

"Huh…?" Asura looked up and realized what Rudy was talking about.

"So bright… so beautiful…" He glanced around him and saw the color universes.

"I still don't know half of the things you mentioned, and my knowledge is nowhere near your vast knowledge. You were right about all the things… except one. I don't have the power of the void."

"Indeed… I should have realized that."

If Rudy had the power of void, why would his body leak light as his powers?

"Your power is… cosmos…" Asura uttered in a broken voice. Seemingly, no longer interested or motivated in anything.

"All this time I was talking about how the universe will give your power to someone else…. but your power itself is a part of the universe. And currently, you are going through a phenomenon called… big bang.

I should have realized this sooner, but I guess I was too arrogant and ignorant to see it. You were going to destroy the third reality, and the remainder of your existence would have automatically created the fourth reality.

I was… Like you, I was used as a pawn by the universe." Asura chuckled wryly and wondered, "What are we? Tools for the universe? Used and disposed of like trash."

"You are also mistaken about one thing. The power of the void you were looking for actually exists."

"It does…?" Asura asked with a glint of hope in his eyes. "Do you know who possesses that power?"

"I do."

"I doubt… you will tell me…"

"I can tell you."

"Why… would you do that? Why would you help me despite knowing my intention?"

"The person who possesses the power of void is in front of me."

"Huh?"

"It's you. You have the power of space, which includes the void too."

"Oh…" Asura's head dropped as his hands supported his body from falling flat.

"All this time… I had the power… yet, I couldn't achieve my dream… my goal. Where did I go wrong? What did I do to deserve this? I was forced to become like this… and now… I…"

"When you have everything, you have nothing." Rudy quoted what Asura had said to him.
