The Outer World was visible in front of Zerathis and Azathoth. It was a large bubble while Aster was kept in it.
Despite all that, Aster kept boosting up his power, now at 50% where his perception over everything had came to a halt.
Concepts, laws, nothing moved. In this state, Aster is now able to set his mind into the future, now allowing him to predict each attack movements and patterns.
That was when the Outer World shattered like glass.
Aster: Hey... that was pretty rude, don't you think?
Azathoth: Knew you'd escape. I see your mana is now at 50% of its true power...
Aster sighed in relief as he nodded, but also noticed how everything is gone. It's just the void itself that's left standing.
Azathoth glared at Zerathis, gesturing him to attack, and as it attack, the attack output from Aster was too immense that—with little difficulty—had completely annihilated Zerathis and everything that makes Zerathis, it.
Aster: Killing Zerathis was simple... I got rid everything that made it, it. That even includes completely getting rid of its immortality and all the split-souls. Though, it's still not dead. Not yet at least. It will revive again in another thousand years.
Azathoth: How poetic. So you made it mortal again by removing the concept of immortality from it, then killing it... such a smart move..
Their banter were quiet as they stood there in the void within six feet.
Azathoth then attacked with beams of darkness that is capable of destroying any and all things instantly. Though Aster had completely nullified that.
Of course, it was part of the plan as it cleanly sliced Aster in half with a quick and much faster slash. It had less power, but it was much quicker than before.
Aster could barely evade it.
Aster: Damn! Even with this much power, I can't outclass him!
Aster shouted to himself in his head as Azathoth had then changed the plot and its script entirely, making it so that Aster's ability was completely nullified permanently.
Though, nothing happened. Aster wasn't affected by the effects of the plot being changed and rewritten.
Azathoth was now recognizing Aster as an opponent who won't die.
Azathoth: Truth and Falsehood... both binary 1 and 0.. our existences Aster, haven't you realized that your existence and mine are almost similar in a way...?
Aster glanced at him with uncertainty as he unsure what he meant. He understood the term binary 1 and 0 though he couldn't make out what he meant by their existences being similar.
He had thought about it for some time, and that was when he remembered.
Aster: Ah... right. Both of those concepts aren't applied to us gods. Like how both Yin and Yang was never something that applied to us since the beginning.
Azathoth nodded as an enhanced beam of darkness was now surrounding Aster.
He was put off guard for a second as he vanished out of the trap. The beams hadn't land, but Aster had swung the blade which missed.
Azathoth: Existence and Nonexistence... those binaries don't apply either.
Aster: Obviously...
He kept swinging his sword towards Azathoth which landed some deep cuts, completely stopping his immortality and everything he has.
Azathoth then grabbed the blade and had thrusted the sword towards Aster while he blocked it and kicked Azathoth.
His aura was fluctuating a bit more, which had completely hit Aster. Azathoth was just toying with him.
His body had completely changed and had taken a form of Zerathis. This had shocked Aster while Azathoth was too calm.
Aster: Shapeshifting and taking forms of others.... dammit this is stressful!
He yelled to himself as Azathoth started summoning out and using Zerathis' infinite split-souls and used it against Aster.
He was dodging all their attacks and destroying all the souls as Azathoth kept using all of Zerathis' attacks.
Azathoth (in Zerathis' voice): Keep trying...
At this point, Aster couldn't do it anymore. All the split-souls had attacked while he stood there. They started piling up on each other and as they do, Aster had immediately went straight to 100% of his power.
Aster had reached his peak. His final state in the fight.
Azathoth: Aster Solis... 100% of your power. You're truly revealing to me why you're called the Strongest Outer Guardian...
Azathoth had shapeshifted back to normal as Aster he stood there. The Divine-Destroying Sword had disappeared completely from his hands.
Aster: Let's finish this...
Due to now reaching 100% of his full power, his soul will now be affected and has only an hour to end the fight.
To Aster Solis, distance and speed didn't matter as a concept, as he rewritten the plot and script in a way that Azathoth never existed. Though of course, that didn't work.
Azathoth: What a state...
Aster: When I use 100% of my power... it takes a large toll on my soul plus gives me an hour of not being limited by any means. So I'm free to do whatever I like.
His hair was flowing white color as his eyes had completely changed to yellow. He had looked more divine as his outfit was changed to a divinity white coat that moves down to ankle-length with a black waist band over it, gray shirt and a lovely gray pants of white gaiter-style boots with black fabrics under the white sleeve-like part of the v-shape cut.
Azathoth sighed as he chuckled slightly, but it had seemed that Aster had already attacked. His long flowing hair moved one with the void while Azathoth had stood there, unable to heal.
Azathoth: ...I see. In that state, you've reached complete freedom and omnipotent.
In a way, Aster had completely annihilated Azathoth's metaphysical body. There were wounds blown into his body.
Aster: Well... it's conditionally. I only have omnipotence and only reached the state of Nirvana completely only at full power.
Azathoth had tried to heal, but he just floated in the void.
The Ephemeral God is a form and state that only Aster could achieve, though it requires to use the soul as a life force which is why it takes a large toll. It was a state that removed all limits from him and his abilities itself conditionally.
He had sighed in relief as he noticed Azathoth still had his wounds blown from his attacks and sealed him off completely for eternity.
Aster had reverted back to his usual and normal form as he feels a little sting from his soul, though due to his infinite stamina, he wasn't exhausted.
He snapped his finger reversing time completely to rebuild it again. This would also mean everything that was destroyed had been rebuilt, Yuki being resurrected as well as Kris.
Though, this even meant that Arthur—father of Yuki—was also resurrected and back alive.
Yuki immediately snapped awake, seeing he's laying bed, and had noticed he's still looked like a fifteen year old.
Aster appeared in front of him with a gentle smile.
Aster: Hey! You're awake. How'd you sleep?
He asks with gentleness and kindness as Yuki examined the room, seeing everything looked the same.
Yuki: What happened...?
Aster: I resurrected you, plus rebuilt everything through reversing time!
He said with some excitement while Yuki glanced at Aster, seeing his feminine appearance.
He was unsure why Yuki is staring at him like he had seen a ghost, though he was still disoriented.
Kris, who is now laying next to Yuki, had woken up and noticed Aster.
Aster: Good morning to you too.
Kris: Hey... what the hell! Why am I in bed with Yuki! What did you do!
Aster raised his hands up surrendering as he chuckled nervously.
Aster: Nothing! Definitely wasn't the author's plan to do this! Anyways, I just reversed time to rebuild everything.
Of course, his claims were a lie. Despite being the one who reversed time, he sat down quietly as he tries to figure out a way to expand the limit and fix the consequences when going 100%.
Yuki: Hm..? What is it...?
His soft, quiet tone reverbed through the entire room.
Aster: Eh? Nothing to worry about Yuki. Besides, let's all head out before I perform one last thing to the world.
Yuki and Kris both glanced at him with uncertainty on their face. They both sighed in unison as they stand up from the bed.
Aster's magically changes clothes into his "Ephemeral God" outfit, though with an updated version of a white and yellow cloak draping from the shoulders with a popped collar, yellow tie and white shirt, gray pants and the same gaiter-styled boots with white hair and yellow eyes, and black waist sash over the coat.
Hours went by as they had left, they had chatted while sharing different information. Aster, Yuki and Kris smiled at each other while they roam through Star City.
Aster: Well this is my time to head out. I'll uhh... see you guys later.
He waves as Yuki and Kris waved back.
That exact moment is when everything was resetted. Yuki lived a normal life as a fifteen year old while Kris lived as the Queen of Hell still.
Aster was happy with himself.
The End.
