Esper Harem in the Apocalypse

Asura created a bigger sun and launched it at earth.

"Die, you worthless existence. You won't be missed!"

Asura stood on the sun and waited for the bigger sun to collide and engulf the earth.

"The rendezvous point, or rather, the town 'Hel' is not a place, but a spot in this universe. I don't need the town or the planet to access that point."

Z-Zap!

A light passed by Asura and headed towards the sun that was moving towards the earth. But a second later, the sun's size slowly decreased and decreased, and it eventually disappeared.

Everything happened so fast that Asura didn't even have time to react, let alone comprehend what was happening.

"What?! Impossible!" Asura jumped from the sun and stopped in front of Rudy. "How is this possible?! How did you escape my space domain?!"

"I was feeling a little hungry," Rudy scoffed. "Needless to say, I ate it."

"You… you devoured my space domain?!" Asura exclaimed with a baffled look on his face.

"I also ate the sun," Rudy said while rubbing his hand on his stomach. "Do you have something to drink?"

'True… a void's job is to devour everything. A black hole that eats up everything, even the light. I should have expected this to happen,' Asura uttered inwardly.

"I guess I should have gotten rid of you before attacking the human world. But worry not, I will do that now!"

Asura once again trapped Rudy in the space domain, but he didn't stop there. He created layers of multiple space domains until Rudy was no longer visible inside.

"You can't eat it now. It will never stop expanding, and thus you will never stop devouring it. Still, this is not enough to kill you, but at least I can now destroy the human world without—!"

CRACK!

Asura's space domain cracked as Rudy's hand penetrated it and ripped it apart before coming out.

"What?!" Asura exclaimed even louder. "I understand that you can eat the space… but how did you touch it?! That's impossible!"

Rudy stretched his body, saying, "Actually, I have no idea how I did that. But I guess your powers aren't as strong as you make them out to be. Or perhaps, your space domain is actually weak."

"Weak…?" Asura muttered. "Weak? And me? Are my powers weak? That's preposterous!"

Asura turned into energy and surrounded Rudy inside it.

"I will show you who is weak!"

"Sure, but not here!"

Rudy collected the energy, teleported outside the universe, and said, "Let's do it here."

"How did you do that?!" Asura asked while manifesting a half-human form to his chest.

"Ever heard of teleportation?"

"Yes, but you should not be able to use it in space. It has no factual… never mind. Our powers are far beyond one's comprehension. I should stop getting surprised at everything you do," Asura sighed.

"You know…" Rudy stared at Asura and uttered, "I don't sense any hostility from you, even though you wanted to murder billions of people. Why do you want to do that?"

"The answer is quite simple." Asura shrugged. "They don't deserve to live."

"And who are you to decide that?"

"I don't need to be anyone. Strong rules the world and the weak in it. I am a God, and I can do whatever I want. I am more surprised why aren't you doing anything?" he scoffed in arrogance.

"In a living world or in any existence, power has always been everything. A supreme position that no one can defy. If you can do everything, then why not do anything?

When you want to achieve something, you have to do something. Every living existence needs three things in its life. First is, of course, fear. The second is, obviously, fear. And third is also fear.

It's nothing personal. All people inferior to you are nothing but your tools. It doesn't matter who they are or what they do, if there is a need, they must be sacrificed. In this existence, from the very beginning, winning has always been everything. As long as you win in the end, that's all that matters.

I learned the hard way, but that's the only way. You seem very naive to me. Why must you care about the worthless existence you don't even know? I fail to understand that. Please, enlighten me, my Lord."

"And here I thought my powers had made me arrogant…" Rudy sighed in disbelief.

"What was that? Do you think I am arrogant?" Asura asked curiously.

"You haven't realized it yourself? That's hilarious, really."

"My words have been nothing but the truth. If anything, you are a little too naive. How old are you? It seems that you haven't seen the world yet."

"I am 18, I guess? Metally 23, maybe?"

Asura manifested his complete human form and asked, "Are you lying?"

"Why would I even need to lie to someone who is going to die soon, anyway?"

"If you are really 18, then…" Asura shook his head in disappointment and uttered, "So… fucking… ridiculous."

"..."

"Hah!" Asura scoffed out loud and shouted, "Was the universe so desperate to be protected that it gave such unfathomable power to a kid? Seriously, if anything, I pity you, lord.

The universe stole everything from you in return for what… these powers you are not even using for its true purpose? No wonder you are so naive."

"What are you trying to say? Didn't you just say powers are everything, and now you are contradicting yourself in the next statement?"

Asura furrowed his brows at Rudy and asked, "Answer me, Lord. Why do you think you have these powers?"

"To protect the universe from the evil douchebag like you?"

"You are funny. These powers are given to you; you have not done anything to earn them. The universe just chose you among the billions and gave you this role of the Lord.

It's not a position of a boss, you are but a pawn of this universe… chosen to do your job— which is to rule over everything. If you don't do it, your powers will vanish, and someone else will get them. And I am damn sure the next person to hold your power won't be as naive as you."
