Esper Harem in the Apocalypse

Asura shook his head in disbelief and asked, "You didn't know, did you?"

"No. There was this malfunction when I received the power. It's not at its full potential yet, or maybe you would like to hear— it's not awakened yet."

"I have been in this third reality for a year, and I can confidently say I know about it more than you do," Asura proclaimed while creating a space ring around his body.

"By 'terrorizing' and 'sacrificing' people for knowledge? Get in the line, I already have to deal with that blue moon shit."

"Oh? So you know about the blue moon?" Asura asked curiously. "Well, well, maybe you are not as dumb as I thought you were."

Asura knelt down a little and spread his arms as he smugly said, "I am the king of the blue moon."

"Uhh… blue moon is for the vampire, and you are not a vampire."

"Argh… I guess I was wrong. You are stupid, after all." Asura created a blue moon out of thin air and said, "This is a blue moon. Why would you even think it's related to the vampire and not a universal thing?"

"The human world had only one moon before the partition of the world and races. I might be wrong, but that's what I was told," Rudy shrugged.

"You weren't provided knowledge of this universe with your powers?"

Rudy shook his head and said, "Dude, I didn't even know I had these powers."

"Wait, are you really the Lord? Or am I talking to an imposter?"

Rudy snapped his finger and obliterated the blue moon Asura had created.

"Why are we having this not-so-friendly chat again?" Rudy asked.

"You and I both know that we cannot win against each other. Perhaps, I can if I fight seriously against you, but I don't know about you. Your powers seem lackluster to me, but that might be because you don't have any 'real' fighting experience.

Have you ever fought with someone at your level?" Asura asked curiously. "I fought the Gods of my reality and usurped their throne."

"Unfortunately, I am so strong that I never met anyone at my level. As for fighting seriously… Oh, you have no idea what I can and can't do."

"I said this before, I want to have a chat with you before I kill you. So tell me, my Lord, what do you know about the blue moon?"

"What makes you think I will answer you?"

"I will answer your questions if you answer mine. Or we can fight and fight that will continue for eternity."

"I don't like when someone asks me to choose from 'their' provided options, so I always make my own option."

Rudy clenched his fists and stood in a fighting stance.

"So you chose the second option anyway?"

"No, I chose both. We will talk while fighting." Rudy punched Asura in space and sent him a million kilometers away.

However, Rudy received a punch the next second and was sent a million kilometers away in the opposite direction.

"I like that."

Asura caught up with Rudy and said, "This would be my first direct attack on you. How was it?"

"Not impressed."

Rudy created a sun, split it in half, and smashed it on Asura from both sides.

"Hey! That tickles! I thought you said we would fight seriously!"

The sun was engulfed by the space while Asura walked out of it.

'I reduced him to atoms with my first punch, and he still somehow regenerated. He said he is immortal, but they should die when they are killed, right?' Rudy wondered. 'Usually, in novels and games, there would be a so-called powerful weapon to kill the gods and whatnot, but I myself am a weapon and still can't kill this dude.'

"What's wrong? Thinking about your next attack?" Asura asked jokingly. "You shouldn't give an opening to your opponent, or you will end up dying."

Asura spread his hand and clapped loudly.

"..."

Rudy wondered what Asura did and waited for something to happen, but nothing happened. Until he looked at his body.

"...!"

It was devoured by space, and only his eyes were in the universe.

"How was this one?" Asura asked with a smirk on his face.

Then, he created a throne from a nearby star and leisurely sat on it while facing Rudy's eyes.

"Let's see how you get out of that."

Rudy's entire body except his eyes had ceased to exist. If they were cut or damaged, his powers could immediately regenerate his body, but that wasn't the case with space.

Asura had rewritten Rudy's existence, or rather his body's data, and made him a bodiless existence.

Asura snapped his fingers, and a tree grew out of his throne, which sprouted all kinds of fruits from one branch.

He plucked a grape from the veil and showed it to Rudy's eyes.

"Want to eat?"

Then, he scoffed out loud and said, "But you don't have a mouth to eat."

After finishing the grapes, Asura let out a sigh and said, "You still haven't done something?"

"..."

"What's wrong? Lack of motivation? Maybe I should go and destroy the human world? Would that make you motivated?"

Rudy's eyes glowed brighter after hearing that.

"Hah! Got you!" Asura threw berries at Rudy's eyes and said, "Don't worry. I no longer feel like doing that. I find you much more enjoyable. But who knows what might happen if you don't entertain me?

Hence, let me entertain you instead." Asura pondered for a second and said, "You wanted to know about the blue moon, right? I will tell you. But before that, you have to learn about the realities you lot call 'existence.'

There is a simple word to explain what reality is, and that is… big bang."
