So, remember when I said that this was supposed to be a one shot? A story that shouldn't have gone beyond just one chapter? Well, I wasn't kidding.

I was coming up with shit on the fly, and I didn't even really have a direction or an ending towards which the fic was going. Hell, I didn't even know who was behind Subaru's looping!

Now though... I thought of an ending that 99% of you will hate, and I am planning on going in that direction. So prepare to be disappointed.

His meeting with his parents didn't end too well, all things considered. Even though he had that heartfelt talk with dad at the end... killing millions is not something easily forgiven.

But that was fine, that was what he expected in the first place.

He managed to shed a tear - that was more than enough for him. He wasn't solely capable of anger and jealousy, sadness was something within his reach too.

'I should make that a permanent memory.'

Using some simple spells he made, he permanently engrained that moment in his mind. Now, no matter what happens to him, he will be able to recall it.

It was a trick he had been using a lot during these loops. After all, his mind was not perfect, he couldn't recall everything he saw.

For the very important moments, he had specifically made a spell to graft them into his mind.

The reverse was also true. He had been deleting some of the memories that were useless to him, so that they wouldn't clog up his thinking. A memory-wipe, so to say.

In fact, during the loop where he made himself immortal and waited for the end of the universe, every single minute, he deleted the last minute of his memories. That was the only way he could deal with the loneliness during that restart.

'I should stop with that. I have things to do, it's no time to daydream.'

With another classy snap, Subaru reappeared at the circle connecting the two worlds.

And then, he just stared.

He stared and stared and stared. For hours, for days, for weeks, for months, for years.

'...What do I do?'

―That was the question that has been tormenting him for the last hundreds of loops.

He had already done everything, he had already made everything, he had already explored everything and he already knew everything.

For the last couple of loops, he had been doing nothing but grabbing at straws, hoping for something to happen, even though he knew it wouldn't work.

All he did was optimize on the paths he already tread. There's no way something like optimization would stop the loop and yet, he tried, because he had already tried everything else.

'What do I do?'

So what was he supposed to do now? What had he not tried yet?

'...Only that? Really?'

He knew what he could do, hell, he had made a plan for himself at the very start of the loop, but he still decided to take this time to think. He could never have too many plans.

He was in no rush after all.

With a sigh, Subaru started modifying the city-wide magic circle.

Since this time the circle was nothing more than a mana-construct, he had no need for Invisible Providence, and he just used his mana to affect the circle.

Using Beautiful World, he could easily have the entire circle in his senses, and he could see every single nook and cranny of it.

Using Hopeful Preservation, he made sure that the world couldn't take away his mana and that he was always in top shape.

Using all sorts of magic spells, he sped up his thinking and fragmented it. He was now thousands of minds in a single body, all of them enhanced.

Slowly, making sure not to waste any mana, over several months, he worked on the circle.

'...All done.'

At the end of it all, the circle's diameter doubled in size.

Now, this was not just a circle to travel between two dimensions, but a circle that could find dimensions, connect to them, and make a bridge between them.

'Now... let's see if there are more than two universes out there.'

He activated the magic circle while using Unstoppable Escape to escape from the world's laws and limitations, and he started searching for other universes.

At first nothing popped up, but then, slowly, Subaru could feel other universes.

There were countless of them, which was no surprise. There should be infinite universes after all.

He wasn't even surprised about the fact that some universes were very similar to his, or very different.

No, what he was surprised about, was that countless universes were being destroyed and rebuilt every single second.

'I see. So that's how my looping works.'

There was no doubt that there were other versions of him. Which meant that there were also versions of him that could loop.

And the universes being destroyed and rebuilt? That was just how his 'looping' worked.

This made sense. After all, time travel comes with all sorts of paradoxes, so there's no way he was actually travelling back in time.

With all the knowledge Subaru gathered, he could definitely say that destroying and rebuilding a universe was easier than time travelling.

Another interesting note was that Earth and the other world weren't actually different universes like he thought at first.

They were just different dimensions, all trapped in a sort of bubble called a universe.

"So dimensions and universes are different things, huh? And dimensions are lower on the hierarchy."

Subaru got... stupid lucky.

He did not consider that dimensions and universes were different things, so the fact that he could feel universes at all with his magic was a miracle.

This magic circle was made while studying the connection between Earth and the other world, after all. Which meant that - logically speaking - it should've only been able to see other dimensions.

'Did I roll a nat 20 or something?'

With a stupid thought like that, Subaru tried to build a bridge to the other universes... but failed.

"Well, no shit. With my knowledge, travelling to other universes is still out of reach."

A glint of determination appeared in his eyes.

"Dimensions on the other hand..."

His own universe contained thousands of dimensions. How much will he be able to learn from them? Just what kind of insights could he gain there?

Perhaps... he will even find something that could help him excape the loop.

This is a very short chapter all things considered, but I think that's fine. I'm the type of person to not care about the length as long as the meaning is transfered.

Now, a very important question. There are three things I can do with Subaru's travels to different dimensions:

1. I can skip them. 2. I can skim over them. 3. I can write them (comparatively) fully. Like, every dimension having a couple of scenes connected to it.

Of course, no matter the option I won't talk about all the dimensions (that would be hell), but I just want to know your opinion on how much I should write. I don't want to make this story too bloated, considering the fact that I take pride in how 'bite-sized' this story is.

Your opinions will be greatly appreciated.
