Welcome to the Moon Cell's core, Haru Kishinami.
This voice sounds familiar, yet so alien. A close relative, yet another species. Like coming from my own mouth, yet not necessarily a human language.
I am no voice. I am the Moon Cell Automaton.
Is… this the part that I tried to hack? The one that is supposed to grant these wishes of mine?
No, that is inaccurate. I am the Automaton, I run the Moon Cell's core, the whole Moon Cell and the world as it is.
This is the higher logic behind it all? Behind the whole world? It can read my thoughts and answer me, so that does not seem too far off. Or maybe, my whole life is just a program being run by this very "Moon Cell Automaton".
Your assumptions are as correct as they are not. Everything that happens, every possibility along with every timeline, I run them. I calculate them. I dictate them.
That means, this is a God talking to me. But…why? Was I not supposed to win the War? But, as the Moon Cell Automaton controls everything, would it not choose its victor beforehand? How could Twice meddle with it?
I do not choose a victor. I run the Holy Grail War, in a place within this very Moon Cell—which you called a "simulation". However, I have no control but the SERAPH over any events. Despite hardships and being unfit, you have won with your own might. It was not my decision.
But, then why am I here? Why am I neither deleted, nor back alive? What happened to Saber… to Mordred ?
This is something you have yet to find out.
I won. If I am not being deleted, the changes I made should be compiled and processed, leading to their fulfilment, right?
Yes, they should. They would. But, I, as the Moon Cell Automaton, do not possess the capacity to run your changes at this time, I am afraid.
The Moon Cell Automaton that runs the whole world is out of capacity ? This must be a joke. Why? How can this happen?
A threat has appeared, for myself and the whole world. The complete universe is in danger. My full capacity is needed to prepare a way to remove this threat. However, this is futile. I cannot be saved, and thus neither can your earth.
Wait… The whole world is doomed? And I do not even get to spend the remaining time anywhere but here? This cannot be true…!
It is true.
Can I do nothing to change this? Just… anything. Everything Mordred and I went through cannot go to waste. I cannot leave her abandoned!
There may be a way. You are unfit as Master, yet you possess a very special quality. Haru Kishinami, with your aid there is a small possibility of success.
I will do it. Whatever it takes. For the world's future, for my own… And for Mordred's. Or hurting her was for nothing.
You will have your consciousness transported into a place within the Moon Cell's highly sensitive core. I will summon Heroic Spirits to support you, from timelines this version of you have never seen.
Mordred…might be one of them, right? I could see her again.
Before you make your decision, Haru Kishinami, there is a crucial effect to consider: The port will not necessarily be without fail. Your cyberframe may be destroyed in the process, or split again. Even I cannot foresee the exact risk as the Umbral Star itself already infiltrated my core.
I do not mind. This is the only chance I have to give myself and Mordred and even the whole universe a future—whatever the risk, I will take it. I seem to be the only one able to do so, and I owe it to Mordred. And Rin.
Very well. Haru Kishinami, you will gain your consciousness after the port has been successful. I will be able to process and thus grant your wishes only should you be successful.
And with that, I black out.
