"So, you agree to anchor yourself to this world?"
"Yes," Rider agreed to the deal.
"Sakura, when I anchor her to the world. You should lose your command seals. Losing Command seals means you are no longer a participant in the war"
"I accept, I don't care about the wishes. I care more about Rider" Sakura blushed when answering.
Cael could sense love, shyness, and lust from Sakura with his mind's eyes.
'Is this Rider 'Bewitching black serpent' part of Gorgon? That means she must be in love with Sakura and Sakura must have reciprocated. As long as she agreed to me, it doesn't matter how. '
"Very well, go to church and tell that you would like to give up your command seals. Meanwhile, Rider stays with me. Oh, if you encounter anyone annoying like another servant, break this Glass piece"
"Alright" Sakura took the tiny mystic code and left for the church.
Cael stayed along with Rider to create a mystic code with shards of Grail.
"So, what more secrets are you hiding?"
Rider asked as she moved closer to Cael.
'This Grail war is a way to reach third true magic but I won't say it. Also, Reaching Magic can't be that easy' Cael thought but he acted like he was innocent.
"What Secrets?"
"Really? You didn't even say your true name to us and you can do things other magi couldn't. Even us servants need some incantations but I didn't see you use one till now"
"...."
'That's actually a good observation. I should use some bogus Aria to divert this type of attention. I will remember this '
"I'm talented and I'm not bragging. Without my talent, I would probably be just another magus. As for the name, let this war complete"
Rider moved even closer, her chest pressing against Cael's back.
"Oh~, then how about I thank you for everything you have done~?"
However, Cael rejected "No, thank you. I just had an Orgy and I don't think I can go for more sex even if you use your bounded field"
"So, you are even aware of my noble phantasm. As I thought, you are no ordinary magus"
Cael didn't respond to her anymore and Rider also didn't bother him. He created the mystic code in a short time.
"Rider, get naked and Lie down. I need to graft this circuit into your body"
Rider did as told and Cael drew the mystic code onto her back.
After it is done, he asked "So, how do you feel?"
"I don't feel any rejection from the world"
"It's magic we are talking about. No magecraft can do this miracle. So, about the deal, how about we start with an easy experiment?"
"What shall I have to do?"
"I will deploy my reality marble, tell me your experience"
"To think you even have a reality marble. Just how strong are you? Whatever, do it"
"Let's go outside"
Cael and Rider faced each other in the backyard
"Try to resist as much as you can"
"Okay"
Cael began his 'Aria', he can deploy wordlessly but others don't need to know that.
"Domain Expansion : Cosmos of Eternal Stasis"
The entire reality shifted, Cael's Reality marble manifested and then Rider who is about to attack froze on the spot.
"So, even something closer to the Divine spirit can be frozen in time. Since Time is a meaningless concept here. Rider will be sealed here forever with me but only an instant will pass in real life even after an eternity in here, in a way, this is an entirely different world that is ever existing. Not gonna lie, that's a strong Reality marble"
Cael closed his reality marble and Rider who is in a position to attack saw that Cael is still standing there not doing anything.
"When will you deploy your reality marble? Two Arias are not enough, you know "
Cael just smiled and said "Thank you, the experiment is complete"
"What?"
"I deployed the reality marble, it can tamper your memories. I'm sure you don't remember that you said 'I love my master' right?"
"I didn't say tha-..oh, I get it. So, Is there anything else?"
"Yes, I will try to summon you into reality marble. Again, try to resist it"
Cael tried to summon Rider into his reality marble but he can feel resistance.
"That's annoying but it's easy to resist your summoning"
He told her to not resist but even then, he couldn't summon her.
'So, I can only summon non-living things from outside. The Consciousness is resisting my attempt to summon it. So, I am the only one to freely enter my reality marble when it comes to living beings, but If I deploy the reality marble, it will drag others'
"Next, show me how you use mana burst"
After learning a few things, he decided to stop it.
"Okay, that's enough experime-"
Cael paused mid-sentence and said "Rider, stay here"
He changed his appearance into that of masked Jack the Ripper from the record of Ragnarok and teleported.
He blocked the attack from a lance with his cane and stood protecting Sakura.
"My my~, attacking a young lady in the middle of the night is not a gentleman's behavior"
Cael scanned the surroundings, he found Saber, Lancer, Gilgamesh, Kirei, Shirou, and Sakura.
'I expected this to happen and asked Rider to show me how to use mana burst and enhanced sensing. It can be useful just in case'
Cael already calculated that Sakura will encounter Shirou when he sent and the end of this war is near. So, he is not at all surprised.
"Gilgamesh, kill him"
"The Fuck, who are you?"
Gilgamesh tried to use his mystic eyes to discern the true name of the mysterious 'servant' but he couldn't because Cael already hid his being from reality using the Halo of resurrection.
Multiple golden ripples appeared in the sky as Gilgamesh launched multiple Noble phantasms at Mach speed.
But the moment they approached Cael, they all stopped mid-air.
"What?" Everyone is surprised
"Ah, you must be the so-called supervisor. This young lady is no longer a participant in the war, shouldn't the church offer protection?"
Cael said while he held one end of the cane against Kirei.
"You are her servant? Don't you have a wish? Why did you give up? You could still participate in this war and get your wish if you don't want your master to be harmed "
Kirei is certainly amused by this servant who looks strong.
"Wish? I don't have one, in fact, I have many wishes. Those cannot be granted by mere mortals and their pathetic creations, Only someone like a God can quench my thirst for power. "
Cael respected Gods, not because of their existence or worship but he respected them for their power. Some like Odin have omnipotence in this verse which he respects the most.
Heroic spirits are like cheap versions of Gods. They have power but it is very limited.
"That's a pity then, how about I kill your master here since you don't want anything?"
"Your words are enough to discern that you aren't doing your duty anymore. So, I take it I should destroy you and your servant"
Cael didn't plan on a grand fight to defeat Servants.
In his book, it's pure suicide.
And it's Gilgamesh here who is arguably one of the strongest servants, if he's given preparation time and observation time, even a God can be defeated by him.
This Gilgamesh is somewhat weak as he has a physical body and is human in a way.
So, he decided to go all out.
He activated Gravity Jail and used the maximum amount of force on just Gilgamesh. He also used Halo's concealment ability to conceal the attack such that no one can detect it.
Gilgamesh couldn't do anything when facing such intense pressure and died on the spot getting crushed into oblivion.
The Noble phantasms disappeared signaling that Gilgamesh is dead. Cael's focus shifted to Kirei who is still in shock.
The rest of the servants and masters are also shocked by turn off events.
It's Gilgamesh and he died.
"It's time for your death now"
That's what Kirei last heard before he is also crushed into oblivion.
"You are one hell of a servant. To be able to defeat him without much effort, Wish I could battle you"
Lancer stood even after the death of his master due to his battle continuation.
"My apologies, I don't like battles and your master is also the priest? That's surprising, I thought he was only master of the Golden Servant"
"Whatever, He wasn't supposed to be my master anyway"
With that Lancer is dead.
'Berserker, Archer, Lancer, and Caster are dead. Rider is no longer a participant in this war, Saber didn't give into Kirei's temptation so, this is in a way fate route but the reasons may change. I should talk to Assassin"
"Can we go 'master'?"
"Yes" Sakura replied meekly, she still doesn't know what is exactly happening. All she heard is a voice saying just go with the flow and believe in the masked man when she destroyed the glass piece Cael gave her.
"Wait! Sakura"
"Senpai, I'm sorry. I was forced to participate in this war, I didn't want to harm you in any way"
"No, I'm just glad that you are alright"
'Right, I forgot the important part' Cael thought as he turned to Shioru.
"Young man, The war is not over. Not until the vessel of the true grail is destroyed. It's the master of Berserker, you could either kill her or search another way. But as long as she exists as a vessel, this war is not over yet. I don't like this meaningless war. She must be staying with you right now. So, Do something about it.
"Illya? I see, I will ask her"
While Shirou thanked Cael, Saber on the other hand has other thoughts 'When did he spy on us? This Servant must have been the greatest assassin in his life to be undetected even by me'
With that, Cael took Sakura by flying and turning themselves invisible.
"Sensei, is that you?"
Sakura has experienced flight with only the magus who took her as his apprentice. And this 'servant' appeared right when she destroyed the glass price. She is able to identify Cael with that.
Cael's clothes changed to ordinary clothes and his appearance also returned to his disguise of an ordinary-looking man.
"Sakura, I know you gave grown up in Japanese culture. To some extent, I'm Japanese too but please call me Sir. I feel more comfortable like that"
"Y..Yes, Sir"
Sakura isn't surprised by Cael's strength, he's been mysterious since day one.
