The Chaldea Security Organization is a secret agency founded by Marisbury Animusphere, one of the Clock Tower's twelve lords, and sanctioned by both the Mage's Association and United Nations. By bringing together the most brilliant minds in magic and science, Animusphere aimed to guarantee humanity's existence for at least the next hundred years. The most vital part of this operation is the Animuspheres' crown jewel, the Global Environmental Model 'CHALDEAS', a complete and total simulation of Earth in all eras of history to monitor any anomalies within the timeline.

Within the very confines of this advanced structure holds the remaining members of Chaldea that includes the last two masters of humanity, Fujimaru Ritsuka, Gudako Ritsuka, Mash Kyrielight, Leonardo Da Vinci, Fou, and the staff of Chaldea who survived and witnessed every singularity that was been fix from the very beginning of their journey that also includes the many servants that they've summoned from the Throne of Heroes itself.

Usually, the number of servants that was been summoned created a very good liveliness to Chaldea and it was very eventful every single day.

However this day is not going to be a normal day for the two masters.

It's all because of the last saint quartz that they had in their last summon.

Ritsuka and Gudako are now standing in front of Chaldea's summoning room. After countless hours and weeks of grinding they were able to gather a lot saint quartz from their duo grinding and finally the two of them are ready to summon new servants instead of those accursed Mapo Tofu, Black Keys, and other craft essences.

Ritsuka: All right this is the moment that we've been waiting for sis are you ready.

Gudako: Hell yeah! Lets do it bro time for gacha gacha gacha.

Ritsuka: easy there sis don't get too worked up i know that your excited and me as well but we have to be patient since we don't want to end last time you remember sis?

Gudako: Yeahhhh i don't want to remember that memory again.

(FlashBack)

Ritsuka: What The Fuck!? I Can'T Even Get Single Servant From This Summon This System Must Be Broken You L##sy P##ce Of S##t Give Me Back My Saint Quartz.

The servants look at their two masters the first one was arguing and insulting the summoning system that he was not able to get one servant in his summoning and the Gudako was already throwing a tantrum all over the floor crying, shouting, and spouting offensive words to the summoning system but luckily the servants was able restrain the two of them and knocked them out unconsciously and put the two of them in their seperate rooms.

(END OF FLASHBACK)

Fujimaru: Yeahhh let's not do that type of thing ever again agreed sis.

Gudako: Yeah i agree

Fujimaru: And also sis have you seen Mash i haven't seen her since this morning.

Gudako: Ohhhh yeah she told me that she was busy helping out Da Vinci Chan sorting out some of the paperwork that needs to be finished this week but she's going to arrived here momentarily after.

Fujimaru: Ohhhhh okay

And so the two of them finally started their summoning session using 10 saintz quartz from their first summon and they acquired Mapo Tofu and some Black Keys at the very start of their summons.

After summon and summon they were not able to get one single servant at the end of their summoning spree it was a complete despair for the two of them.

Fujimaru: why why why after countless tries why didn't we get a single servant at the end

Gudako: it's like the universe prevent us getting new servants this is sooooo depressing i think i need to sleep off this horrible nightmare they call reality.

Fujimaru: i second that as well sis i just need some time off from all this heroic summoning spree.

When the two of them were about to lose hope Mash entered the summoning room and asked them what happened they said to her.

Fujimaru and Gudako: the universe hates us Mash we did not get a single servant.

The two of them spoke at once with the same answer to Mash and she was getting worried that her two masters well throw another tantrum in their seperate rooms but she will not let that happened once again and so she reached out in one her pockets that she was able to obtain one saint quartz from their hours of grinding she save that quartz just for this specific moment and gave it too her two masters.

Fujimaru: Mash this is!

Mash: Yes senpai i was saving that quartz just for the two of you.

Gudako: Mash your an angel .

Fujimaru: an angel that gave us her last gift to us and how can we ever repay you Mash.

Mash: just don't do that type of thing were you well start throwing a tantrum and that makes me scared and sad when i look at the two of you.

Fujimaru and Gudako: we promise Mash.

Mash. Okay senpais

And so the two masters and Mash following the two of them they were now using the last saint quartz that was been gifted by Mash to them and in that unexpected moment the blue orbs started connecting to other orbs and it formed a sparked and created golden pillar of light that shined through the halls of Chaldea and the masters and Mash herself were covering their eyes so they won't get blinded by that golden flashed of light but that golden light was been changed into something more extravagant the golden pillar was changed into a cosmic celestial radiance the two masters were in awe that they've never seen the cosmos this up close

Fujimaru: wow it's so beautiful

Gudako: I agree it really is beautiful its like you can easily touch the cosmos itself don't you agree as well Mash

Mash: yes senpai its so pretty

Some of the servants were heading quickly to the summoning room to check out what kind of servant that there masters summoned when the servants arrived they were in shock that there masters was observing a pillar of cosmic radiance that something out of the ordinary could never happened.

Emiya: everyone do you feel that power and magic coming from that pillar.

Medea: yes Archer it seems our masters summoned a powerful servant that i have never felt liked this before.

Arturia Pendragon: and something tells me that this servant is going to reveal itself momentarily.

Gilgamesh (Archer): Hmm if the two mongrels were able to summon a powerful servant that has not been recorded from The Throne Of Heroes then this trip well not be a waste of my time.

Leonardo Da Vinci: i wonder want kind of servant that these two were able to summon and i can't wait for this servant to reveal itself ohhhh im getting goosebumps already.

Jack The Ripper: wow look at those stars there are so many of them.

Nithingale: (Completely observing the beautiful night sky that was been created by that cosmic pillar)

Merlin: well well well it seems this is going to be a fantastic observation towards this new servant. This power and magic it's something unique.

Unknown to them a voice spoke to the two masters.

??? This is rather unexpected that i was been summoned from another universe and it is rather enticing i must say.

The servants were suprize that an unknown voice spoke out of nowhere.

Fujimaru: uhhhh did you guys hear that

Gudako: yeah i heard it too as well

Mash: umm senpais you two should turn around so you can see who made that voice.

And then out of nowhere the pillar of cosmic radiance was been replaced by something extravagant that they've never witness before in their life it was a dragon that has the body of the cosmos itself even his hair was utterly beautiful and also they noticed a golden crown that emits a powerful cosmic radiance to it that he is wearing on his head that has the aura of a respected entity. All of the servants were amazed that they've never seen this type of servant before in their lives.

Cú Chulainn: now that was unexpected don't you agree Caster me

Cu Chulainn (Caster): yeah that was suprizingly cool i might say what about you teach what is your opinion about this new guest we have.

Scathach: hmm based on my observation this new servant is uniquely interesting to say the least it's not just its appearance but also its powerful aura that its emitting its incredible

Cu Chulainn (Caster): yes i can feel it too teach overwhelmingly primordial itself. Hmm maybe i should spar with him so i can test his powers directly what he is capable of what about you Lancer me are you going to challenge this new servant?

Cu Chulainn: im up for any challenge but we still need to wait for our masters to introduce themselves to this new servant in the meantime i just want too observe this new servant carefully

Cu Chulainn (Caster): well if you put it that way i guess your right he is pretty interesting

Scathach: indeed he is

Gilgamesh (Caster): so the mongrels were able to summon an unexpected servant that i was not aware of interesting (looks at crown) and that golden crown its emitting a powerful enchantment.

??? So this is the origin of that source of magic

Gudako: umm what are you talking about Mr. Servant sir?

??? That golden pillar of light that shined upon from the material plane where i currently reside from before ending up in this new universe that you two summoned me.

Fujimaru: where exactly are you from mr. Uhhhhhh?

??? Ohhhhh dear lord i almost forgot the most vulgar of all things introducing yourself to the ones who summoned you.

Every single one was confused about the statement that he responded to the two masters of Chaldea.

??? No matter i shall give you the privilege to witness my True Name.

Every single servants was tense and hype about the name of this new servant literally every single servants from Chaldea was watching and observing this unique servant from the summoning room some of them were asking questions to themselves on where did this servant came from, on what universe did he reside in, what is the name of that universe that he was referring to many theories were escalating from their minds but they were interrupted by the voice of the new servant.

??? Servant Class: Ruler

And then he paused then created something unexpected in his hands it was the birth of a new galaxy swirling in his cosmic hands every single servant was amazed and terrified at the same time that this new servant has the power of creation itself.

Gilgamesh (Archer): so this new servant has the ability to forge the cosmos itself interesting.

In that moment when all of the servants were observing carefully witnessing his might and power. Aurelion Sol spoke once more getting the attention of all servants and the two masters in the summoning room.

??? My true name is Aurelion Sol The Star Forger. One of the most oldest celestial dragon in existence before the birth of creation itself.

The servants were astonished about their new guest that he announced his true name. And his title the Star Forger was a worthy name and a special one as well.

Aurelion Sol: so summoners may i know the names of whom summoned me.

Fujimaru: ohhh right sorry my name is Fujimaru Ritsuka it's a pleasure meeting you Mr. Sol.

Aurelion Sol: Mr Sol?

Fujimaru: did i said something wrong to offend you Mr. Aurelion sir.

Aurelion Sol: no summoner you did not offend me in any way i was just merely suprized that you referred my full name into a singular point of statement. And its something new to begin with but you can call me Mr. Aurelion, Sir. Aurelion, Mr. Sol or Sir. Sol that you referred in your introduction summoner

Fujimaru: ohhhhh okay Mr. Aurelion

Aurelion Sol: wonderful now then what is your name other summoner.
