Chapter 5. My omnipotence Mom(?) expects to much

The ride was relatively smooth moving at a fast pace, could've been to Antarctica within an hour or actually 20 minutes based upon how fast Gilgamesh has said the top speed can go, it was truly unbelievable.

During the ride Gilgamesh told stories of an event called the Grail War where there are usually around 21 participants, masters each with a servant fighting for the Grail, although in Izuku's world there was only one Grail War the one in Fuyuki back in Prequirk time of 2004 with 7 masters and 7servants.

Some timelines it happen either later or earlier and was actually the 5th or 6th Grail War, but all of this was fought over some Grail that can grant the person any wishes they wanted.

In other timeline and universe there were horrible consequences to those who won, while in their world the winner got their wish Granted.

Izuku liked the stories, but he hated one part, summoning servants to fight and destroy one another, sure their were some form of comrades but some servants and master were horrifying individuals.

All of this was done in promise of a wish fulfillment.

Izuku decided what he would do if there was a grail war he doesn't know if it'll work but he'll try, he doesn't want the servants to fight each other, for their masters own personal wishes, but then isn't this what he was doing summoning these heroes here to be his servants for his goals, doesn't this make him a horrible person, a hypocrite, isn't this like slavery...

A light chop was delivered to Izuku head, "Izuku, you gotta calm down a little, stop muttering so much, I understand this is a habit but at least separate them from words you want to speak, and words you want to keep quiet."

"Now from what I can gather your feeling guilty isn't it, you feel wrong for summoning us making us do your work for you like slaves... well Izuku you have nothing to feel guilty about this." Gilgamesh says patting Izukus head, while they glide across the surface Indian ocean, as some flying fish were coming out the water.

"Wh..what?" Izuku choked out.

"You heard me, summoning servants has been around forever and it's been used for many things, some for ambition of their own, some for a wish that benefits all or just one, but ultimately Servants aren't slave they have their own free will, even though we are summon to fulfill masters orders, but we don't have to follow through those master orders."

"For example like some Master who are incompetent or hasn't earn a servants trust, loyalty, or even companionship which led them to use the command seals to forces obedience..."

"and I don't see you becoming or doing those things, you have a goal and Noble dream to carry out despite how foolish the aspect of your Dream are, I still believe you'll make it a reality, and with all your Servants wholehearted support, so don't look down but look forward with your chest out because you'll bring the world to a new age."

Izuku wasn't used to being praised so much so he felt embarrassed that someone was praising him other then his parents, but he did as Gilgamesh said, stood up with his chest puffed up, and was struck in the face by a flying fish who just flew out of the water.

This scene didn't go unnoticed by Gilgamesh who just started laughing

"Fuhahahahaha"

"It's not that funny," Izuku says while rubbing his forehead and releasing the lost fish. Soon the laughter died down.

"Well, Izuku I am quite glad your so considerate, my time here in this world I only had a few master, they were mostly considerate people like yourself, very thoughtful and treated servants like friends or compatriots,"

"My Archer class was a summon of my youthful years so I was quite arrogant, but I did meet masters and humans who were definitely mongrels in which I despise, but that's in the past now let us continue watching the view shall we?"

"Fine, but can you fly a little bit higher because that's a lot of flying fish coming towards us" Izuku asked.

"Very well then"

And Vimana flew just a bit over the flying fishes range.

"Did you fly so close on purpose"

Silence~~~~~~


Back at the Midoriya Residence

"So they really did just leave, without asking me huh,"

"Yes"

"Why didn't you leave with them Nightingale, you seemed like you were ready to go on this trip"

"Well, that's where Gilgamesh got me, he knew I would stay behind to look after someone, and it's not like Commander can't summon for me when they need help, but they may not need it since Gilgamesh is with Izuku."

"I see you have quite the faith in him, is there a reason why?"

"Simple, most servants during their time of summoning have probably met each other a few times, so since now we have retain those copies memories I have seen him in action, I mean you too haven't you Mrs.Midoriya?"

"You can call me Inko, I mean Gilgamesh does it anyways, and yes I understand where you are coming from."

"Understood, so how goes the process of trying to begin homeschooling commander?"

"It will be a bit tough, but shouldn't be too hard after all I did finish my degree before deciding to just settle down, and being a housewife to spend time with Izuku."

"I see"

To say the least Inko maybe adjusting a little bit better then what most would expect, and the conversation was quite normal as they enjoyed the afternoon tea.


Antarctica

"Wow, it so cold here what are we looking for again Mr.Gilgamesh?"

"We're not looking rather we're going to a location to get our answers, and there it is," soon Vimana lands in front of a large snow pile in the mountains.

If one were not to take a closer look no one would notice the odd shape of the snow pile but when getting closer it would seem to be to symmetrical.

"This won't do"

"What do you mean Mr.Gil? Ahhhh"

Without finishing his question Gilgamesh set the surrounding snow on fire melting it to reveal a building and an entrance.

"There much better, Izuku I present to you Chaldea Security Organization, a place where I met one of my masters within such timeline anyways let's head in shall we?"

"Oh the door is locked well then that won't do"

With that a explosion rang out, the door was blasted off its hinges, and Izuku could only stare in shock,

"Mr.Gilgamesh why? Wouldn't this alert the Government or related officials"

"Calm down, I made sure to check the facility earlier, and made sure it won't alert anyone of my return or rather Our intrusion, additionally Izuku don't remove your scarf this building hasn't been touched in a hundred years or so, the inside definitely has collected quite the Dust, another good reason why Nightingale wasn't brought along she may have insisted on cleaning this whole place by herself."

"Sigh* the throne give us knowledge of the era's but I guess not the the extent of everything huh, but it seems like they just left, this place while dirty was just dust and grimes collected over the years no trash, no items or material scattered so what happened here I imagine humanity would want Chaldea to stay open in case more threats to humans so..."

Before Gilgamesh Completed his thought Izuku ran forward like something calling for him,

"Izuku wait, don't go running ahead it's dangerous"

"Scratch that this is an empty abandoned facility what dangers could there be?"

After what seemed like tens of minutes the pair arrived at a door, and Gilgamesh couldn't help but wonder how did Izuku get led to this place this place is...

"Da Vinci's workshop" Izuku says out loud.

"Izuku how did you?!" Gilgamesh ask in surprise while yes he thought Chaldea would hold some answers and through his premonition he was able to see them getting answers, but it didn't show Izuku's sudden revelation.

"I...I don't know, but should we head in?"

"Sigh* I don't see why not, you problem child"


~Somewhere in a Japanese Agency~

Achoo*

"Oh, Eraser you got an secret admirer out there for you? Or maybe right here, it me now let get married!!" A women with sea foam green hair calls out to the tired scraggy looking homeless man

"No,and big no for that last one Joke, I feel like someone just stole my future catch phrase tsk*"

"Is that Joke?! Eraser have you finally followed my footsteps?!"

"No stay back Emi you are not doing that again, nooooooo!!"


~Back to Chaldea~

"Wow this place is amazing, wait Da Vinci as in Leonardo Da Vinci, he worked here wait he was summoned here?!"

Izuku yelled in suprise, as one of the master of the renaissance was a summoned servant here, but at the same time that explains so much of the items that were all over this room.

Gilgamesh couldn't hide his smirk, this kid summoned the King Gilgamesh and a Legendary Nurse Nightingale and he was now going crazy over Da Vinci so he decided to play a joke on Izuku or rather something he'll learn soon enough,

"Ah, Yes indeed, they indeed did summoned "He" the legendary artist "himself" to Chaldea to help humanity two hundred years ago "he" was of great help"

"Umm.. Mr. Gilgamesh why are you emphasizing he so much, is there something I am missing," Izuku asked worriedly.

"No worries, oh and it looks like we'll have our answers soon enough," a staff that looks like a piece of art work was picked up and handed to Izuku.

"Izuku, as I said before we servants aren't slaves so don't feel guilty of summoning us, you can return those servants that don't want to come along with you back to the throne but I believe you have what it takes to unite servants under your ideals and goal to change humanity... no this society into something the humans are proud to live in so go ahead, and summon this servant to find out the answers to our question,"

Izuku nodded as the same set up was placed, and payed down the staff.

"Throne of Heroes please answer my calls"

The familiar blue light surrounded the room and swept up the papers leaving a mess, and from this a beautiful women appears wearing a beautiful dress of blue and violet red, her appearance reminds Izuku of the Mona Lisa,

"Wait did I somehow summon Mona Lisa is she a heroic spirit?" Izuku thought to himself and the figure soon spoke.

"Nice to meet you once again(?).

I am servant Leonardo Da Vinci.

Yes, from now on, I will be Da Vinci-chan only for you!"

"Oh so I just summon Leonardo Da Vinci that's all, wait... Da Vinci's a women?!"

With that a light tap on Izuku's shoulder woke him up from his muttering.

"Izuku you see the throne hero are at time based upon legends and myths the genders at time are either hidden, or changed due to different events, so not all servants will be summoned in the Genders that you know, at times it's based on true history that humanity either hides or doesn't know, but Da Vinci case it just because he chose his ideal beautiful form, so he is an exception to that rule."

"Indeed I am,King Gilgamesh, as this body is the perfect and most beautiful one could be, but that's beside the fact my experiment and planned work"

in which she hurriedly grabs Izuku into a hug and spun him around, who was very Shocked at what happened just now.

"So it was you, what purpose or rather how and why did you create Izuku's Magic Circuit and command seal?" Gilgamesh asked a serious tone.

"My purpose is simple and complex at the same time, why don't we have a seat I'll go make some tea and I'll tell you from the beginning."

"Izuku's mother will have my head if I allow you to make anything here for Izuku to consume, that's been sitting here for over a hundred years." Gilgamesh says while watching Da Vinci opening a containers.

"Oh please who do you think I am, I prepared for this moment, so I have some nice Chai Tea I stored away safely here I'll be right back."


Few minutes Later

"Um... thank you Mr.. er Ms.DaVinci?"

"Your welcome Izuku you can call me Da Vinci, but I am pretty sure you guys wanted the answer by now,"

"So I won't cut corner but two hundred years ago servants were banned from being summoned after the world erupted into chaos with widespread of quirks appearing,"

"The officials and mages feared that the existence of servants would have the danger of exposing the two or rather three different side of the world, which would bring in more chaos where we have regular humans, Quirks, and Magic. I am assuming you know the dangers of exposing Magic's to public right?"

"So one by one we were sent back to the throne and Agents of Chaldea basically lost their jobs and I was the last to go, seeing everyone leave, we couldn't do anything with the original director and family head of Animusphere deceased, funding were no longer available and no voices of support we lost our grounds." Da Vinci spoke in a tone that was slightly sad but still seemed to continue on.

"I don't blame the officials the appearance of quirks was already a issues of it own, no one knew what to do,"

" there were calls of putting people with quirks down, locking them away, or even experimenting on them, it didn't help that crime rates sky rocketed for people with quirks they used those powers to harm others weaker then them, while some quirked people were ostracized by family and friends,"

"Izuku you probably understand where I am coming from, but the history of how quirks started wasn't pretty, so the Government who knew of our existence shut us down as the exposure of more unknown would only bring more instability to society, of course the Mages who doesn't want to loses power due to Servants."

Da Vinci finishes with another sip of her tea.

"That being said I didn't just want to disappear back to the throne, when I was first summoned I was told that I wouldn't be here for long, as there was no way to maintain me here, so I founded a way to become a permanent servant because I don't know when will I ever get a chance to be summon again so I took matter into my own hands, and well I felt the same way when I was told to be returned, but it felt worse, as I won't be able to see the Staffs, other servants,my fellow artists, Mash, and Chaldea's Masters Fujimaru Ritsuka and Ritsuko."

"All things must come to end just like in life but what if it didn't have to be, so I went straight work before I was returned, I began to experiment on Ritsuka and Ritsuko's magic circuits and command seals, it was indeed a gamble as unlike the mages bloodline this will be completely new form of hereditary abilities,"

"but since this would be all new there won't be anyway to tell if it works, to put it simply I was able to make the magic circuits of the Fujimaru Siblings into a hereditary form that would gain more mana over time and would be more connected to the throne in order to be able to summon servants,"

"so judging by this you must be one of their descendants, I already knew that from when you summoned me but nice to meet you again Izuku, no worries Mash and Fujimaru's were on onboard with the idea to meet again."

Da Vinci calls out in A very happy tone as she shook his hands.

"The same for me Da Vinci, but I have a few worries, wouldn't the government be mad that we broke the law, and wouldn't this cause trouble if more people are aware of magic making you guys disappear, and well the last one isn't a concern but is there more people like me in the family?"

"Well Izuku, you don't have to worry about the government you see while they have banned the servants summoning they never have banned magic itself and well since it's technically not a law so they have nothing to be mad about,"

"secondly this is actually something I have discovered about quirks, they aren't as natural as it seems, they are by products of Goeita one of the demon god of Solomon,"

"they twisted Solomon idea into a goal in which almost forced humanity into extinction and Chaldea solved it by going into the past and solving histories crisis caused by the Demons called singularity with each one solved we were closer to ending Goeita's plan on incinerating humanity,"

"we thought that by solving a singularity we would fix all the problems, while it did fix it was to an extent, as it turns out and what remains of Solomon goals of a perfected humanity (although by incineration) was turned into the forced evolution, that slowly came to be Quirks of today,even if magic was revealed it won't weaken our existence but we are still no at the level of the Ages of Gods"

"Wait so is quirks Magic then?"Izuku wonders before starting to mutter

"Well that's a no it's more of a by product, the forced evolution to become the perfect humanity that the demon gods were trying for as they believe that it was their goal,"

"but it does mean that people with quirks can't use magecraft, and the potential of magecraft are in the quirkless population, it essentially like a trade off."

"Although it seems that magecraft potential is still rather low even with these changes, I guess we'll have to go to the Clock Tower to see what are the changes, oh and to answer your last question no, I made it so specifically would only allow one individual to be able to bare both Magecraft potential of a magic circuits and the connection to the throne, so when one appears the others would disappear if they were born quirkless, if they had quirks, well they would've never experienced anything."

Izuku tools out a notebook from somewhere and begins to furiously take down notes, which made Da Vinci chuckle,

"Oh, I can tell we're going to get along just well"

"Da Vinci, we should probably head back it's getting pretty late and I would prefer not to get on Inko's Bad side for when you two mother meet one another" Gilgamesh says while arms folded.

"Mother?" Da Vinci and Izuku asks in a confused tone.

"In a way Da Vinci like your mother although not birth mother, she was the one one who gave you these abilities through your ancestors, actually wouldn't that make you a great grandmother, hm well we should hurry up."

"Well I am more into idea that Izuku would be my student while I am his mentor, but I wouldn't care if he was my son I'll still teach him the same."

Izuku meanwhile didn't know what to do, was Gilgamesh and Da Vinci joking what going to happen when he gets home, how will he explain to his mother.

"The same now, is there anything you need to bring?"

"Oh, if you would be so kind, this whole workshop please."

"Sigh, if this wasn't for Izuku I would've never agreed to allow my gate to be use for such task."


After an Hour Later

on the Ride over the Indian Ocean

"Da Vinci, Izuku has fallen asleep, no?"

"He has indeed, and how may I help you Gilgamesh," Da Vinci answered while Izuku slept on her lap.

"Cut to the chase then, there is more your not telling us Am I correct" Gilgamesh asked in a slightly tired voice.

"You are indeed, while I am telling the truth about wishing Servants like us get a chance to comeback to earth again that's only half of the reason, some of the Past events may not have been wipe up completely and are to possibly return to ruin humanity once again, The reason why I didn't say so was because Izuku is so young,"

"just like Mash she was young along with the other Children that were made to save humanity, I couldn't possibly stomach the idea of doing it again I didn't think that fate would have it once again to give such task to a young boy..." Da Vinci says with a bit of sorrow in her voice.

Then Gilgamesh spoke,

"While it is true Chaldea did many horrible things in order to save humanity, hasn't history always been like that through wars, battle, conquest,and much more,

"and before you say anything else that boy your holding in your hand has potential he is stronger then he seems and will be up for any task if it means to save another life."

"Also, Izuku your Not good at Lying nor pretending, so you might as well get up" Gilgamesh said bluntly.

"I still don't know how your mother is so easily fooled by your 'I am okay,' but that doesn't work on me, and Da Vinci how did you not notice."

"Was... was it that bad?" Izuku ask

"Yes it was,"Gilgamesh answers.

"Oh, but I was sure that you were asleep when did you wake up"Da Vinci asked

"Uhm around ruin humanity portion, but Da Vinci don't worry I'm not afraid, I will train my hardest so that I don't disappoint you or any of the servants that I would summon in the future,"

"together or even if it's just me I will do everything that I can to defend humanity or as much as I can with my abilities, I won't make you regret making me the inheritor of this magic circuits and command seal I promise." Izuku tells Da Vinci in full confidence.

"You know, Izuku I feel quite proud already, like a mother watching her son growing up so fast, hmm let's sign you up for a university!!"

"I am sorry your doing what now? But I am only 9!"

"No worries we'll work hard"Da Vinci says while winking and holding a thumbs up to Izuku.

As the conversation begins, Gilgamesh could only shake his head and laugh tirelessly as he look forward as he piloted Vimana back home to Musutafu, while holding a picture of Him, Izuku, and Da Vinci posed with a colony of Emperor Penguins, he smirked.
