Seasoned murderer

"My sister… was killed by my own hands."

The Dimension God stated woefully after regaining his composure.

Meanwhile, our protagonist was left stunned on the spot for a few seconds before he recovered with an outburst.

"Haaa?! What was that? My apologies sir, but I don't think I heard you properly… My ears don't seem to be working today. Haha... Could you please repeat what you had just said?"

Zero started sweating bullets and thought he was just hearing things.

"Your ears are fine, kid. You heard correctly the first time. Yes, I…"

God gritted his teeth and hesitated for a bit before speaking again.

"...killed my very own blood relative. Although it wasn't intentional, it still remains a fact that I was the one who had killed her."

The deity finished sadly.

"I-I see."

The raven-haired teen stuttered nervously. He had not expected the result to turn out like this.

The Dimension God sighed as he noticed this and began thinking back to everything that happened, before proceeding to explain to his successor exactly what had taken place back then.

"You see, as long as one reaches our realm of power and divinity, you are able to create dimensions which essentially becomes connected to you as a part of your own being.

The dimension created comes with many perks to which the main one enables the creator to become stronger the more developed his/her dimension is and this entirely depends on the strength of the living beings within the dimension, regardless of their race.

Whether they be gods or mortals, monsters or beasts, devils or angels, etc… you get the gist.

Anyway, it might've been because we were twins, but when our two siblings had created our own dimensions, a peculiar situation had appeared.

The dimensions we created turned out to be parallel to each other, but in a rather strange way one might say."

The god paused for a moment, allowing time for Zero, who was now rather curious about all this dimension stuff, to urge the man on by quickly inserting a question of his own.

"Strange? What do you mean by strange?"

"You see, there wasn't really anything wrong with how our dimensions developed at first.

But that was until I found out that except for one location present in my own dimension, the rest of the worlds I had created just weren't able to host living beings no matter how I tried to change the environment.

To make it even worse, the creatures that lived in that world became extinct before a new species emerged and even then, it still took them a couple of hundred thousand years before they gained the intellect they have now.

Though what irritated me the most was just how they weak they were.

Their strength was close to nil and for some reason, I couldn't change it, almost as if there was a higher rule applied to my dimension which had stripped me of my god's authority. Pretty frustrating if you ask me."

God explained in slight annoyance.

'Eh…? How come that world sounds strangely familiar… almost like…'

The raven-haired teen was lost in his thoughts before getting pulled back to reality by a deep voice which practically solved his doubts in one sentence.

"Before you say anything… Yes, that world is the Earth where you had lived all your life."

"Uh huh… So those creatures that became instinct were dinosaurs then?"

Zero asked after nodding.

"Yes kid, but that's not the point here."

God started to sound slightly impatient.

"Ah, my bad my bad. Please continue as you like Sir."

Zero indicated the god could continue while having an embarrassed expression on his face to which the deity just shook his head in defeat before speaking up again.

"Anyway, unlike my dimension which seemed to have a ton of unfixable problems, my sister's, on the other hand, was blooming with every passing millennium.

The dimension consisted of various worlds and each included several developed civilizations of different races. Whilst the majority of them were only of meager strength, there were still numerous worlds with advanced civilizations and decent power.

Certain worlds even contained beings whose power even rivals that of two to three realms below me. Unfortunately though, those guys are bound by the dimensional laws and have to rely on themselves to break free of the shackles which in other words is a breakthrough in realm."

"Interesting, so how are you and your sister's dimensions even considered parallel to each other, if the differences between the two were that far apart?"

The teen asked again, though it was a proper question this time.

"Good question, this god was just getting to that."

The middle-aged looking deity nodded his head in approval.

"Since you are someone who has watched a lot of anime along with having a considerable amount of manga and novels read, I'm fairly certain that you can basically guess the situation between both dimensions, now that I've revealed a couple of things to you that is."

God glanced at Zero with a knowing eye, which confused the teen. The fuck did watching anime and reading novels have to do with different dimensions?

Wait a minute…

Zero's eyes which had a trace of confusion had now turned bright with clarity as he finally thought of something.

Parallel Dimensions…

Anime… Manga… and Novels…

Add in the fact that one Dimension is severely weaker than the other…

"Don't tell me… that the various worlds in your sister's dimension… are actually anime worlds… along with all of the possible novel and movie worlds from Earth?!"

Zero's eyes shined with stars at the possibility. Wouldn't that mean he'd be able to go to all those worlds in the future?

'How interesting!' He thought with excitement.

"Mmm, that is true… though it is quite intriguing to know that some of those worlds in that dimension are basically just different variations of the Earth from my own dimension."

The supreme being nodded and then proceeded to explain further.

"Time runs differently between the two dimensions so my sister and I were able to notice and figure out the similarities quickly.

Now I know what you're probably thinking - that the multiple worlds in my sister's dimension were created by the human imagination originating from the parallel dimension, but that's where you're wrong.

The worlds residing in my twin's dimension had already existed in the first place as they were created by her, long before those anime and novels in my dimension were written and produced.

In fact, even I don't know why, but the mortals in my dimension seem to be able to depict the future of the worlds within my sister's dimension through the form of an anime, novel, manga or movie, whatever it may be. Even games are included.

In short, the different scenarios present in those anime and novels are actually like a set future for those worlds.

This means that it is highly likely, and almost certain, that the path of each world will follow what is specifically shown or mentioned in the anime or novel, that is, if nothing external to the world interferes with the particular timeline."

'Well, that's actually pretty fascinating now that I think about it. Doesn't all of that just prove that fate is a real existence? Doesn't that also mean that my meeting with the Dimension God is also a kind of fate? Then is it possible for someone to escape their fate? I mean, all those protagonists from different anime/novels can do it… Hmm... maybe that's what it means by breaking the shackles and moving up the realm? Ah, never mind. My head hurts just thinking about it, I better stop.'

Zero thought in confusion as his brain kept coming up with different theories and solutions. He was quickly pulled out of his thoughts though and came back to reality after hearing God continue to speak.

"Anyway, we're starting to get slightly off track here. The real reason why I mentioned all of this is because I wanted to tell you the reason I started envying my sister, which had later become unconcealed jealousy, leading to her undeserved death."

The deity's voice turned grim at that.

"Jealous? Of what? How she was more accomplished in developing her dimension?"

The raven-haired teen asked, raising an eyebrow at the god, which was honestly considered rude, but as they've been talking for a while now, the deity, on instinct, had already learned to ignore his successor's discourtesy.

God sighed.

"Yes, sort of. Although at first, it wasn't really anything major. In fact, I was honestly happy that my sister was able to get stronger as she was always the weaker of the two of us. I even took part in helping her manage her dimension, as I couldn't really do much with mine no matter what I tried.

But it started to hit me eventually, that I was going to be overtaken by my sister in terms of strength and my pride as a man didn't want such a thing to happen. When you add in the fact that I was her older brother and the one who was supposed to be stronger, in order to protect her, it didn't exactly soothe the problem down either.

Many actually don't realize that even gods possess emotions and whilst a certain rumour of how gods discard some of their emotions, due to being deemed a liability and something useless, was somewhat true, only a select few choose to do it. Most gods including us, the dimension gods, retain our emotions since they are one of the very essences that make up our soul and without them, the soul becomes incomplete.

And so my pride, coupled with the frustrations originating from how underdeveloped my dimension was and not being able to do anything about it, made my desire for power, which I thought had long been lost since I had reached the realm of dimension god, sprout again. This further pushed me to make a crazy decision - to occupy my sister's dimension for myself..."

The Dimension God paused for a bit, before opening his mouth once more.

"...and you can basically guess what went down afterwards."

"That…"

Zero frowned. He was perplexed by one thing.

"...how exactly did you… eh… you know… when your sister clearly seemed to be stronger than you at the time. After all, her dimension was grander than yours and going by what you had told me previously, doesn't a dimension god become stronger the more their dimension is developed?"

The deity shook his head at that.

"Dimension gods have different levels of strength too, from low to high-tier with mid-tier being in between the two. The different tiers are subsequently divided into three also, from the beginning-tier to peak-tier, likewise, with the late-tier in between.

My sister was at the mid-peak-tier of the dimension god realm at her bottleneck. Even when borrowing powers from her dimension, my twin sister at most had the strength of someone who had just broken through to the high-beginning-tier compared to me who had long broken through to the high dimension god realm beginning-tier and stayed there for quite a while already.

Although it might only seem like a tiny difference, when someone reaches our level of strength, just a minuscule amount would be enough to dominate the other side in a fight."

God explained patiently once more.

"Even then...the disparity shouldn't be that much, right? Dimension Gods couldn't possibly be that fragile, otherwise, wouldn't having all that power and authority be a joke?"

The raven-haired teen retorted.

"Of course they're not that fragile. What do you take us for?"

God rolled his eyes at his successor.

"Despite the fact that I didn't have any concept of time when I was battling my sister, I still remember fighting her for a great deal of it. Maybe a couple of months of so? We dimension gods obviously don't need to sleep so battles could last up to years even.

Anyway, after an unknown amount of time had passed, I recall myself becoming impatient which had eventually turned into anger. Overcome by rage, I was later woken up to see my sister's apologetic smile whilst telling me through her sorries that she was going to be the first one leaving.

Startled by this, it was only then that I had noticed a fatal injury to her divine soul, something which I had inflicted on her. Usually, if this happens, there is still a possibility of reincarnation due to the degree of our powers… but the wound she was inflicted with was a kind of deadly poison that I had concocted in case there were some unexpected circumstances.

This poison acts fast and is extremely potent against us divine, especially since it was made by a divine who had reached the realm of dimension god. It essentially corrodes the very essence of someone's soul, which means that there is no chance of reincarnation. In simple terms, their entire existence will be removed from the multidimensional universe."

As he listened up to here, Zero felt a chill up his spine and looking closer, one would notice the teen's hands shivering. Fuck man. Although from an outsiders point of view, they could simply say that he was the future dimension god and shouldn't be scared of something like this, he was still technically a mortal at the moment. When had he ever heard such a terrifying thing?

'What a frightening existence to be able to create such a poison.'

Zero thought with terror. The teen after getting a reality check, finally understood how naive his previous ideas were.

He realized that even though the existence in front of him might've seemed chill and extra patient when it came to him, this being was still someone who had gone through wars and a fair share of experience when it came to killing someone.

He was literally talking with a seasoned murderer!
