Back in the nuclear city of Fuyuki as everyone was doing one single thing, which was running away.

There's a hidden rule in the supernatural side in this world, a rule that is supposed to be very obvious and everyone should follow it, which is keeping the mystery a secret.

Mystery is the source of all supernatural phenomenons in this world, everything grew stronger or weaker according to their mysteries. The oldest and mysterious always get an advantage of strength and power, even if those sitting sometimes break here and there, but there's one thing for sure. Only the higher mysteries can defeat other mysteries in this world.

This rule of keeping the mystery as a secret isn't just a random rule, but it's vital for the magi and other creatures. Mystery, according to its name, is more stronger and alive when not a lot of people know about it.

The condition of mystery in the modern era is weaker than it was in the age of gods. Back in the day, a lot of magecraft could be called True magic, but now, there's only five remaining.

For these reasons, magi won't allow the mystery to spread around the world and be known by all, they did everything to stop it, politics, fairy tails, stupid ideas, and even the magic shows on tv to make the world believe that magic and magecraft is just a myth and illusions.

However, today, two servants decided to make their show global and told everyone that there's a possibility of dragons popping out from anywhere or a light from heaven drop on their heads.

The magic association and church were racking their brains to find a solution to the problem and calm it before their agents delete the memories of most of the people, which will make the others look crazy and shut up about it.

But there was one thing for certain, which is what the hell is happening in Fuyuki?! Was a ritual built by just three families this crazy to destroy the world?

What happened in the sky, left a scare in the mind of magi that would be difficult to heal. It was a war beyond words for magi.

Even if they ignored the mystery exposure and huge damage, they cannot let something like the Holy Grail run wild anymore, be it for magic association future or their greed.

However, before the true force of power was sent to Fuyuki, the magic association and the church suddenly stopped all the preparations and announced it was not necessary. They even decided to wait and see while keeping a close eye on the situation by sending some agents.

The huge change in decisions made everyone baffled beyond words, even if the decision was from the Lords of the clock tower and some special members of the church.

However, this didn't stop the magi from figuring the situation, but they received some information that made them pale and extinguished all thoughts of going to Fuyuki.

You can't blame them because the Holy Grail and what happened in Fuyuki was announced as the magecraft experiment of a very important figure in this world and nobody wants to mess with him without preparation.

Meanwhile, in a spherical room with the view of the starry sky, a wooden chair was floating.

However, even if the chair was mysterious and weird with its design, it was completely overshadowed by the man sitting on it.

The man was old and had a beard on his face. His clothes were like a wizard robe, but it was fancier, however, the unique thing was his aura that didn't look like a human at all.

"Hm… This is wrong" the man waved with his hand as a book was floating in front of him and its pages were turning with a quick speed.

"All axis, points, lines, and even possibilities of the timelines were annihilated from that part of the world" the man touched his beard as he was in deep thoughts about the situation.

"Usually when this happens, the 'world'(Gaia, Alaya, and Root) won't interfere and let it die for good, but it seems something is special about that one" the man looked at his book before he sighed and said "Is it because of those unusual readings I received lately?"

Kischur Zelretch Schweinorg, the Wizard Marchal, is in a slight dilemma about what is going around because this has already surpassed his 2nd True Magic calculations.

"What do you think about the situation?" Suddenly, Zelretch said without looking behind him.

"I've to say that I'm surprised that you're the first one to interfere" There was an old phone on a small table behind Zelretch as it started talking suddenly.

"Oh, even if I'm old, I can't just miss all the fun" Zelretch stroked his beard before he said " And if I don't then those kids will send the association to its death while you try to play around"

Zelretch was one that calmed down the situation around the world by making a phone call to the church and the magic association. He announced to the world that the Holy Grail is his magecraft experiment that he was preparing for it for a long time, no one was able to openly deny him because he was a supervisor of the Holy Grail creation.

He pulled the card of 'I'm stronger, so I'll take care of it for you and you don't have to worry' on all the organizations in the world, which made them slightly angry, but more helpless because the Wizard Marchal spoke and there's nothing they can do about it if they care about their lives. Well, some don't care about their lives, but that's a different story.

However, if someone knows Zelretch he'll know that he's trying to protect the association from danger that even he can't contain without paying a heavy price.

"How rude. But you noticed their strength, huh" The man behind the phone, the dead apostle, Caubak Alcatraz, sighed before he said " I don't want to be involved with them, but the situation doesn't allow it"

Dead Apostles were the humans who became vampires by different means, like magecraft or getting their blood sucked by a vampire. Caubac Alcatraz is the twenty-seventh of The Twenty-seven Dead Apostle Ancestors, which Zelretch is in and he's also an old friend of his.

"Solomon and Beast VI, both of them grew stronger to a degree that I don't want them to aim at me" Zelretch tapped his book as the pages started turning again while thinking about the situation.

"Can't they take their personal problems away? One was crowned by God and another by humanity, the amount of contradiction between them is so huge that's ridiculous" Zelretch started to get annoyed by the Christianity related Servants making a mess everywhere.

Solomon, the king of magecraft, from the name you can know that all the magecraft against him is useless and now he has enough power to use other True Magic, even if they are incomplete, which puts Zelretch at a huge disadvantage.

Beast VI, the Beast of Babylon, isn't all that complicated with Zelretch because that Beast can kill him directly. True Ancestors are incarnate natural spirits born from the planet(Gaia) and can be classified as planet-level spirits higher than Divine spirits, however, all these traits of power can count as a huge debuff facing Leo and his planet-killing dragons.

This is a 10x attribute advantage, not to mention the dead apostle like Zelretch, who are weaker against the planet-killing than the True Ancestors.

Zelretch doesn't see any hope for victory in his current condition, which is weaker than his peak, even having clones in parallel worlds is useless if Beast VI 2nd Noble Phantasm was involved, and it's a checkmate across all parallel worlds if the 1st Noble Phantasm caught him. His youth form has a better chance, but those three Noble Phantasms are still a great danger, after all, he was a human at some point.

"I know humanity had the hobby of dooming itself, but for them to allow something like that to exist… I'm totally speechless" Caubak said as he wondered how much humanity illusions and evil can reach to create 7 Beasts of calamity.

"There have been some changes in Beast VI, but those three Noble Phantasm are all linked to each other, they can even be counted as a single Noble Phantasm revolving around the 'Crown' which is very annoying if I might say" Zeltrech remembered Solomon and his rings that can protect him from the Beast VI's 2nd Noble Phantasm as he was speechless again.

"So, did you just come here for chatting because we can do that over a cup of tea or… You're here because of the 'Spider'..." Zelretch said as Caubac was silent for a while.

Spider might be a silly nickname, but that's the nickname of one of the strongest things in this world, the Ultimate One, Type-Mercury, who's sleeping in South America, waiting for the Land of Steel to arrive. Caubac and Zelretch were worried about his awakening because of all the noise Solomon and Leo made.

"The 'Spider' isn't the biggest problem here. Zelretch, do you think we can survive the Forsaken Eden?"Caubac took a while before he said those words that made the expression on Zelretch's face solidify a little.

"No, sorry old friend, but our chances are 0% in the normal conditions, after all, that sealed garden is the biggest rebellion against the Lord and the real authority of Beast VI. Only Beasts, humans, or beings out of the planet can survive" Zelretch stroked his beard before he grinned and said " It's like dropping the Heaven on the mortal world and the thing that Manaka Sajyou was trying to use, which make me wonder what reaction will the church have if they know about his existence"

" That Crown and all the records of evil...*Sigh* I really want to pass because if I'm going to die, I prefer to die by the Crimson Moon" Caubac was having a headache which he didn't have in a lot of years.

"Enough with chatting, do you have anything important because I don't have time to waste with your failed comedian" Zelretch said as it made Caubac almost crash the phone from the other side.

"Look at this…" With those words, the book in front of Zelretch started turning faster before it landed on a particular page.

"This… Might change everything " Zelretch widened his eyes while looking at the page that didn't have any information.

This Book is a mystic code connected with parallel worlds and their information, but there was nothing on this page, no past, present, or future, however, there was one single name… Ritsuka Fujimaru.

Meanwhile, at Fuyuki city, near Mount Edou, there was a group of people walking around… Or floating.

Leo was floating around while talking about something with Archer and Merlin. Nero was still holding Leo's hand with the excuse that my Spirit Origin is still fragile and needs more adjusting, however, she was looking at Rin, who told everyone that they can't stay there, like an enemy.

After everything that happened, the group left the battle scene and proceeded to evacuate because they also don't want to have the unnecessary trouble with the magic association, and the church, even Rin, who was going to get involved anyway, didn't want to be at the scene.

"Hm? I just felt someone was talking about me" Leo looked at the sky as his instincts told him that was someone talking about him, which wasn't strange after all the trouble he caused.

"That to be expected, however, what is the next move in this battle?" Nero nodded for some reason before she asked Leo, this wasn't a question about her actions, but she wanted to hear other opinions, especially her Praetor before taking a step in this war.

"Hunt Solomon down" Leo replied instantly before he said " The smaller time he get to prepare, the better for us, especially for a Caster that has a lot of cards in his sleeve"

"Oh~Umu! Then it'll be a wild attack, no running around and ending with a bang!" Nero said with her exaggerated tone as it made Leo look at her before he said " It seems you're also a supporter of the mayhem route!"

"Mayhem? I don't know about that, but the bigger the shock on everyone faces, the better it'll be!" Nero said as Leo nodded again while Ritsuka was sweating as she was holding the sleeping Fou.

Merlin told her that Fou isn't an adult of his race yet, so he needs some sleep once in a while after some action.

"So, you were sent by Alaya, Archer-san" Ritsuka looked at Archer as Rin was still holding her forehead while she knew that her Servant is a traitor to all magi.

"Ah, at first, it was a normal summon, but then, it became a mission" Archer said calmly while choosing to ignore Ritsuka familiarity with him before he looked at Rin and said " Don't worry, Master, I'm still your Servant, but Humanity survival come first in my job"

"It was just a Holy Grail War, it was supposed to be a battle for the honor of my family, why did the survival of humanity become involved" Rin was having another mental breakdown, maybe that information should be given to her slowly as Ritsuka was tapping her shoulder.

"I see, then the information from Alaya should come from the 4th Holy Grail War" Merlin remembered the time when even he lost most of his Clairvoyance effect on this world before he said " There has been a different summon of a Caster from the last Holy Grail War, but I know nothing except it was close to Berserker( Lancelot)"

"Hmmm… Caster, you say?" Leo tried to look with his Clairvoyance, but like Merlin said, he couldn't see a thing, like something was blocking his vision.

"Yeah, there was a problem in the last Holy Grail, Alaya said it's connected to the Matou's house" Archer stopped for a moment before he said " According to calculations of Human Order, there has been a loss in connection with a human there before it was fixed almost instantly, but Alaya kept it in mind"

"Matou? Archer, what do you mean?!" Suddenly, Rin woke up from her mental breakdown and asked Archer, who sighed because he knew this would happen.

Leaving Archer with a raging Rin, Merlin looked at Leo before he said " Can't you look at the records"

"I can, but I won't, because looking at Humanity sins and flaws all day hurt my brain" Leo rejected the idea before his expression became blank and he said " And… I'm disappointed by her(Root)"

{Disappointed by the Roots, huh… If those magi heard you, they'll question life before hunting you down for their honor} Merlin felt he'd only see new stuff as he was hanging around these guys before he said " That's a shame, it'd be a quick solution if you do"

"....." Leo glanced at Merlin, but didn't say anything.

"Your Servant really loves to talk about humanity and their sins" Rin was trying to shake Archer, but she failed because of his strength before she looked at Leo and Merlin conversation and asked Ritsuka, who seemed the only one who'll answer something even if she was still scared of her.

"Eh? Well, that because…" Ritsuka frowned for a moment before something popped in her head and said "... He's Satan....?"

"Hah…?" Rin raised her voice of confusion before she looked at Leo who was grinning and looking at them.

"Finally, some recognition, and I can finally say this…" Leo nodded with satisfaction at Rin's pale face before he said " You thought it's your regular Servant, but it was me, SATAN!!!"

Archer face palmed himself while holding the fainted Rin, Merlin was whistling, Ritsuka tilted her head at this introduction, and Fou was sleeping.

The Holy Grail seemed to be clouded in more mystery as Satan was happy by finally getting some recognition and making someone faint from his name.
