The incomprehensible creature's presence contains complete malice towards Yuki and is the true embodiment of the concept.
Its aura was so dark that even realities would collapse just through existing.
Yuki stood up with the gun in his hand, though a singular movement had caused this creature to attack. It had released an innumerable amount of arms and tentacles towards Yuki.
Yuki: If you aren't Lillian... who are you?
There was silence. No words spoken by the creature. Yuki couldn't speak to it. This unknown and incomprehensible 'thing' has no soul nor does it exist in a traditional sense.
Yuki had tried to analyze it with Lucian's ability, 「Heavenly System」, there was nothing. The information on this 'thing' had never existed. There was no truth and lies with this being. There was no origin. There was no logic. It truly was unknown.
Yuki had continued dodging its attack, but it had pierced his body through the tentacle that had changed its form into a katana.
Yuki: ...The fuck...? How did it...? It was in front of me...
It was in front of Yuki. In fact, it never moved once from its spot.
Yuki had collapsed as he started bleeding out on the floor. His organs was punctured out of his body.
Its existence could collapse all three layers of reality. It will soon-to-be a 'thing' that could rival even Azathoth.
「ERROR!: DIVINE ORDER SYSTEM SLOW COLLAPSE BEGINS! 「∅—∑—ℵ₀—𝌆」HAD SLOWLY AWAKENED!」
In that moment, the fabric of existence had started to slowly unraveled each other. It isn't an instant collapse, though everything collapses within a year. The name of "it" was too incomprehensible to everyone, it was like "it" didn't have a name, but symbols.
Samuel: We can't win... the Cataclysm.. it's over. We lost..
He murmured as his eyes widened slightly in shock. He couldn't process everything, it wasn't something that could ever be thought about.
Though, Yuichiro had made his return and appeared in Heaven. He sighed deeply.
Yuichiro: This creature is unkillable. There's no traditional way to kill it. It's impossible. If it can't be killed, then what could it mean to all of Heaven and the Book of Creation?
Samuel glanced over at Yuichiro with a serious expression. He knew they were all doomed for death.
∅—∑—ℵ₀—𝌆: A̶l̶l̶ ̶o̶f̶ ̶c̶r̶e̶a̶t̶i̶o̶n̶ ̶i̶s̶ ̶m̶y̶ ̶s̶t̶o̶r̶y̶.̶
A̶z̶a̶t̶h̶o̶t̶h̶ ̶i̶s̶ ̶m̶y̶ ̶G̶o̶d̶.̶
The voice of the Empty Set or the Origin of Destruction had echoed through all of realities. It had gone through everything that everyone could hear it regardless from where they are from.
∅—∑—ℵ₀—𝌆: E̶x̶i̶s̶t̶e̶n̶c̶e̶ ̶s̶h̶a̶l̶l̶ ̶c̶e̶a̶s̶e̶.̶

I̶ .̶ S̶ H̶ A̶ L̶ L̶ .̶ C̶ O̶ M̶ E̶ .̶ B̶ A̶ C̶ K̶ .̶
It kept speaking, but after it finished, it complete vanished causing reality to shatter and become distorted. The loud, warped voice was the one thing Samuel and Yuichiro never wanted to hear.
Yuichiro: It goes by many names... Lord of Destruction, The Eraser, The Empty Set, The Origin of Destruction, and so on.. it isn't unkillable because it doesn't "not just exist", but it is by definition.. has Perfect Immortality.
While Yuki is dead, Samuel struggles were real. At that point, the Origin of Destruction will cause everything to end if it destroys everything but Azathoth.
Samuel: So... we're dealing with a being who can't be killed in any way possible and shape and form... not unless..
He had hesitated quietly as Yuichiro sat down. Not even he would know how to defeat the being.
In the Sea of the Cosmos, 「∅—∑—ℵ₀—𝌆」, had stood in front of the unawakened Azathoth.
∅—∑—ℵ₀—𝌆: L̶o̶r̶d̶ ̶A̶z̶a̶t̶h̶o̶t̶h̶,̶ ̶Y̶u̶k̶i̶ ̶F̶u̶j̶i̶t̶a̶ ̶n̶o̶ ̶l̶o̶n̶g̶e̶r̶ ̶e̶x̶i̶s̶t̶s̶.̶ I̶ ̶s̶h̶a̶l̶l̶ ̶d̶o̶ ̶t̶h̶e̶ ̶w̶o̶r̶k̶ ̶o̶f̶ ̶g̶o̶d̶ ̶f̶o̶r̶ ̶s̶h̶a̶l̶l̶ ̶a̶l̶l̶ ̶e̶x̶i̶s̶t̶e̶n̶c̶e̶ ̶c̶e̶a̶s̶e̶ ̶t̶o e̶x̶i̶s̶t̶.̶ B̶e̶c̶o̶m̶e̶ ̶c̶o̶m̶p̶l̶e̶t̶e̶ ̶n̶o̶t̶h̶i̶n̶g̶n̶e̶s̶s̶.̶
The Origin of Destruction's distorted voice echoed through the Sea of the Cosmos as each word is distorted and glitched through telepathy to Azathoth. Azathoth didn't respond back. It was silence. Until, Azathoth had slowly woken up from its sleep.
Azathoth: I̴... I̷'̸m̶... n̴—n̶o̷t̸... y̵—y̷o̴u̸r̶... g̴... g̷o̸—o̷d̴... Y̴o̶u̷'̶r̸e̶... n̴—n̷o̶t̸... m̴y̶... s̶e̷r̸... v̴—v̶a̸n̶t̵...

(Translation: I'm not your god. You're not my servant. I exist to sleep and dream. Do my job and you deserve nothing but pain and death.)
It spoke through telepathy as the Origin of Destruction had stayed quiet then vanished. Azathoth slow awakening has fallen back to sleep in a displeasing manner.
Each movement from the Origin of Destruction causes reality to warp in a way that isn't possible. Everything in its presence slowly fades temporarily.
The dimensional spaces between everything in the sea of the cosmos had collapsed just by the Origin of Destruction's presence.
In a black, infinite space in which felt like eternity, Yuki had opened up his eyes. He was unsure his situation and surroundings.
This was within one of the possible dimensional spaces as Yuki floated around in emptiness.
Yuki: ...He's killed me.. it hurts. I can still feel the pain. It's like it never fades away. Oh well...
Yuki's emotionless, exhausted and dead state continued going through the space. Both the Origin of Destruction's and Azathoth's presence were so overwhelming that it had reached Yuki.
Despite the warping fabric of reality, the uncertainty of survival had increased drastically.
Yuki: What if...?
He had tried applying a rule to temporarily bring himself back to life, though, nothing had happened.
「Rule cannot be added.」
To Yuki, it was a system that can be heard through the mind. It was a slight and faint ding, then he had another idea.
He slowly closed his eyes in the infinite dark space as he tries to get comfortable. He inhaled and exhaled deeply then relaxed all of his muscles in his body.
In that moment, his astral soul–a form of conceptual conscience–had exited his body completely. Though it was a smart decision, it has a large flaw to this.
Yuki: ...My Astral Soul. In a plane of higher existence–the Astral Dimension–is a place of those who projects their souls in a form of conscience. Though.. if I stay out of my main body for too long, the punishment is I'll die through fading consciousness and soul.
His internal thoughts had been filled with worry as he remained emotionless. It was a thought that scared him a bit.
His Astral Soul had exited the infinite space and returned to the Physical World. His soul had roamed through the world. In his eyes, he can interact, see and harm other souls.
But to mortals, Yuki phases through buildings like a spirit and can't be seen. That was a problem to performing such feat.
Yuki: From my knowledge... this 'thing' that killed me is the true empty set of all existence. This 'thing' has no solution...
He had murmured, the though, nobody could hear his words.
Yuki: so everything around it reduces to zero, which is how everything is being warped each movement. So everything becomes void... concepts like cardinality, extensionality and algorithm is nonexistent...
His voice echoed through the warped space and time while he analyzes his surroundings. He tries to touch a door, though his hand phases through it.
He roamed through the physical world as an Astral Soul as he continues thinking of how to defeat a being like the Origin of Destruction.
He kept walking around, though there was a thought that occurred in his head.
Yuki: Wait... immortality... I'm sure I hear those saying 'it' contains perfected immortality..
Then reality shifted drastically as laws began to warp in impossible ways. Rules had officially been changed everywhere across many realities.
「ERROR! WARPED UNIVERSES AND REALITY COMPLETE! IMMORTALITY NOW IRRELEVENT TO 'IT' BY DEFINITION! CONCEPT OF IMMORTALITY ERASED FROM ACROSS ALL FRAMEWORK OF EXISTENCE!」
The system blared loudly in Yuki's head causing a massive headache. That was the moment he realized, everyone is now doomed to fail.
Yuki's Astral Soul had went around trying to figure things out while Yuichiro and Samuel the Angel watched over him in Heaven.
Samuel: Immortality ceased to exist across the all hierarchical framework of existence.
Yuichiro: Yeah. Everyone and everything has been transcended by 'it' that isn't connected to dimensionality as a whole, including all three layers of reality.
Samuel's eyes widened in shock realizing their fate. It was the end of the world. The Origin of Destruction is the totality of a metafictional existence that governs everything and everyone excluding Azathoth.
The longer the Origin of Destruction continues to exist, the more damage it would cause to everything and everyone.
Samuel: Everyone and everything will get erased from existence completely. Well... I guess this is goodbye, Yuichiro.
Yuichiro: Yeah.. Yuki isn't winning this fight either, so it's all over. Nothing we can do now.
They both stood in Heaven in silence as they accept their inevitable fate. Yuki's Astral Soul had immediately went back into his body. He could only last five minutes outside of his body as a astral projection.
Yuki started to realize that the true horror will come and that the end of existence will soon happen.
