Overluck MC

After Sai finished overwriting Shigure, the next he needs to do is help with the preparations.

"Can you remove this Domain, Shigure? We need to help the others with the preparations." (Sai)

Upon hearing Sai's request, Shigure removed the domain immediately.

"Since you already finished reading the books, I gave you about modern technology and Erdmitte's crafting arts, can I assume that you mastered them?" (Sai)

"Yes."

"Very well. Shigure, help Da Vinci to setup the defense mechanisms, after that help Yukina and the others in setting up the offensive mechanisms."

"How about Father?"

"I will do my preparations as well. Since everyone will be working without sleeping and eating, I need to match up with the pace."

"But Father didn't sleep nor ate in the past days! Even if Father's body is fine but you have been using Creation Magic without stopping your mind must be extremely fatigue. Not to mention Elder Sister (read as: Onee-sama) (Author's Note: Shigure is talking about Jenseits) told me that you are using Time Wheel Pearls consecutively. And since Father is using the Time Wheel Pearls in the past sixteen days, converting that to hours it will be three-hundred and eighty-four hours, considering that two hours outside will be one month inside, it will be one-hundred and ninety-two months inside the Time Wheel Pearls. You are extremely tired now!" Shigure explains sternly to Sai.

"Oh, so you knew it. That's why you determined that I'm currently at my weakest and took that opportunity to attack me earlier. Indeed, in my current state, my mind is exhausted the same with my magic circuits. I would not be able to process my situation properly, nor use Magecraft properly. That will give you a 65% chance of killing me. That is the highest chance of success even in my past life." (Sai)

"I will not do such thing from now on!" Shigure speaks with agitation.

"Haha, don't take it seriously. With seriousness, I'm really impressed, you know. With this, I'm able to determine your skill level. Umu, I can entrust you with scouting and assassination." (Sai)

"Father is lying. You already predicted what I will do and lured me out by going to the garden where no one is present. My real chances are at 5% since Father's estimate is under the assumption that Father is unaware of my intention. It is also a part of your plan to send me the katana and let me recover my memories. How can I assassinate such a cunning Father?" (Shigure)

"Now, now. There is no need to underestimate yourself. You mastered Umbra's Veil to this extent, it is no exaggeration to give you the title Reaper. You will become my shadow after this, so you must know well your capabilities without underestimation nor overestimation." (Sai)

"I understand, Father. I will do my best to eliminate anyone and anything that threatens Father." (Shigure)

"I have expectations for you. On that note, catch." (Sai)

"Y-yes." (Shigure)

Sai tossed a black pearl to Shigure.

"This is…?" (Shigure)

"Primordial Death Goddess' Core. With the rankings of Gods, Primordial Rank is the highest since the order is based on the time they were born. In the past, there were Death Gods with each rank, well this could be applied with all concepts that a god can be born from. Anyways, the only difference in the rankings are innate power, authority, and divinity. The Grim Reaper or also known as Primordial Death God is someone that is very capable, even without his powers as a god, there is a case where he can kill a god with the same rank only using the Umbra's Veil. He didn't get arrogant with his Primordial Rank and polished his skills to perform his duties. Without a doubt, he is a God that deserves respect, even I respect him." (Sai)

"You have learned Umbra's Veil but your mastery is mediocre compared to the Grim Reaper. Swallow that core and practice Umbra's Veil in your free time." (Sai)

"I'll be going now." Sai vanished after speaking.

"In the end, Father changed the topic and ran away." (Shigure)

Meanwhile in the side of the Preparations

Currently, Yukina and friends are doing the preparations for the Raid Event.

"Yukina-san, what should we put in the front gate?" (Miu)

"Spell Canons with Explosion Spell and Disintegration Spell, link the power source with the Mana Core inside the Mansion."

Spell Canon. A canon designed to release spells that is imprinted in the Spell Stone inside it. It can contain two Spell Stones. A normal Spell Canon can fire a spell with the spell's power multiplied by three, but the one that Sai made multiplies the power of the spell by ten times.

"In that case, I will go and talk to Nagato-san. Since she asked me to help her with the monitoring system." (Sayo)

"I'll trouble you, Sayo." (Yukina)

Sayo nods, and uses the wind to fly towards the Mansion.

"Saaya-san is manipulating many golems to set up the heavy equipment, Rinko-san is connecting the equipment's power source to the Mana Core, Chisato-san is checking the condition of weapons, Sayo-san travels back and forth to see if everything is fine with the Mansion and the mechanisms, and Yukina-san is the leader that makes sure everything is going smoothly. Everyone is amazing. Just a message from Sai-san and everyone immediately followed. I wish I can also do the same." (Miu)

"Thank you for the compliment, Furiniji-san. But there's no need to feel frustrated. It just happens that we have the knowledge and the processing to do it. If you want, I will give you a lesson after this raid." (Yukina)

"Really? I will have to trouble Yukina-san. By the way, Yukina-san and the others are not humans?" (Miu)

"Why do you ask?" (Yukina)

"Because it feels like the five of you can think effectively than humans?" (Miu)

"I see. Indeed, the five of us are not humans. We are Artificial Intelligence given a body that bears semblance to a human. Our current state is a miracle that is caused by Sai. As for the feeling you get from us, it might be due to this." (Yukina)

Yukina created a holographic screen that shows a skill description.

•Wisdom Core [Allows Multiple-Thinking. Drastic increase in Calculating Speed. Drastic increase of speed in Thought Processing.]

•Experience Core [Outstanding data processing. Infinite data storage. High speed analysis and synthesis. Organized filing of data. Perfect Recollection.]

•Excellence [Improves the body's qualities. 100% control of the body. Perfect Synchronization of body and mind. 0.0001 second reflex speed. Unique Vessel.]

"See? If it weren't for our physical bodies that greatly resembles a human one, we would be mistaken as robots. Although, that is what we are originally." (Yukina)

"But I don't think Yukina-san is a robot." (Miu)

"Let's get back to work, the Raid Event will not wait for us." (Yukina)

"Yes!" (Miu)

Back to Sai's side.

Cutting off the telepathic link, Sai took out the Eternal Holy Grail.

Eternal Holy Grail. A diamond version and better version of Holy Grail. An obviously cheat item no matter how you look at it. But it is useless once there's no cooperation.

Sai is holding the Eternal Holy Grail playing around with.

"This Grail looks like the Lesser Grail, but in fact, this is equivalent to the Greater Grail. The terrifying aspect of this Grail is that it has infinite energy. I can't believe it at first, but when I asked Mentor and Da Vinci, they said that they were incarnated."

"If there were things to be cautious of, there are two."

"First, the Servant I will summon. It is not guaranteed that the one I will summon will obey, no, they might even attempt to kill me on the spot. I cannot rest assured even if I had forty-two Command Seals."

"Second, is this Grail itself. This Grail has a will of its own. Worst case scenario is that it might took control of the Servants and rebel against me."

"This item is excellent but it carries the risk more fatal than the benefits it provides. What should I do about this?"

While Sai is pondering what he will do, the Eternal Holy Grail shine brightly in his hand. The light only lasted a moment.

[Congratulations! New Features added to Eternal Holy Grail!]

"Hmm?"

[Eternal Holy Grail]

[Eternal Possession of: Sai Kaiku]

[Feature:

1.Throne of Heroes

2.Resurrection of Servants

3.Command Seal Restoration

4.Absolute Loyalty Imprinting (NEW!)

5.Neutrality (NEW!)]

Sai heard footsteps and the last footstep was irregular.

"Mentor…or not. Who are you?" Sai looked at the Scáthach with diamond-colored eyes.

Scáthach kneeled on one knee and speaks.

"I hold no ill will. I am the will of the Eternal Holy Grail." (Scáthach/Eternal Holy Grail)

"It turns out you can possess Servants as well. So, what are planning to do? Don't tell me are you going to play the submissive one after you noticed that I'm planning to destroy you?" (Sai)

"I only d.e.s.i.r.e to serve my master with the best of my capabilities. Master d.e.s.i.r.ed his Servants' loyalty and I granted it. My Master d.e.s.i.r.ed the proof that I will not harm Master and I showed it." (Scáthach/Eternal Holy Grail)

"Is that so. I'll leave it to that for now." (Sai)

"I'm very grateful for your trust." (Scáthach/Eternal Holy Grail)

"What is this Absolute Loyalty Imprinting and Neutrality?" (Sai)

"Absolute Loyalty Imprinting is where the Servant that you summoned will never have the intention or thoughts of harming you. The Servant will also have the d.e.s.i.r.e to fully devote themselves to you. The Servants you summoned earlier have their imprinting done." (Scáthach/Eternal Holy Grail)

"Neutrality is the imposing of Neutral Alignment on all Servants that Master summoned. Leonardo Da Vinci's alignment is currently Chaotic Neutral and Scáthach's alignment is currently True Neutral." (Scáthach/Eternal Holy Grail)

"Will Absolute Loyalty Imprinting work on cases like Brynhild and Gilgamesh? One is cursed and the other possess an ego that even made the All World's Evil's corruption useless." (Sai)

"Yes, it will work without fail." (Scáthach/Eternal Holy Grail)

"Another question. Can you grant wishes?" (Sai)

"Yes. However, I will not be able to grant a wish that Master didn't know how to be achieved. I apologize for the inconvenience that I caused." (Scáthach/Eternal Holy Grail)

"No need to apologize. I already expected that. Can you return to the Grail? I want to start the summoning." (Sai)

"Understood." With that Scáthach's eyes returned back to its normal color.

"Ugh, did I lose my consciousness?" Scáthach groans while holding her head with her left hand.

"Welcome back, Mentor. How's the feeling when the will of the grail possessed you?" Sai greeted Scáthach with a smile.

"So that's what happened. I'm okay, you can tell me what happened later." (Scáthach)

"Since Mentor said so, I will start summoning." (Sai)

"My will creates your body, and your sword creates my destiny." (Sai)

"If you heed the Grail's call and abide by this will and reason, then answer me." (Sai)

"I hereby swear." (Sai)

"I embody all that is good in the world." (Sai)

"I shall defeat all that is evil in the world." (Sai)

"Seventh Heaven clad in three words of power! Come forth from the circle of binding, Guardian of the Scales!" (Sai)

A great cyclone of Mana and shockwaves surrounded the magic circle. This shows how great the Mana that is being poured by Sai in the Ritual. The cyclone gathered in one point and disappeared.

Then, a woman clads in golden armor appeared. Her red eyes are similar to a snake and her golden hair is very long that it reached her ankle.

She looked at me and speaks:

"Fufuhahahahaha!" (Golden Woman)

"Being able to summon me means that you've used up all of your luck, mongrel!" (Golden Woman)
