Rejoice.

"Well, I guess this is progress" Leo had a weird expression on his face as he realized that even an Angel with a huge calculation power like him can't guess some simple things.

To be honest, he's speechless after figuring out the situation, which was bothering him in this Holy Grail War.

There have been a lot of unexplained events during this war. From 14 summoned servants to attacks that didn't have any reason behind them.

More importantly, who were the masters behind some servants that appeared from nowhere?.

Even more, how did some servants like Medea and Lancelot be summoned to this war? Especially Medea, who was clearly an extra Caster like Gilgamesh, who is an extra Archer.

These questions kept bothering Leo a lot during these days. He guessed it'll be the system user Root talked about, who didn't show himself yet. But he wasn't sure because this war is very complicated and confusing.

It could be a hidden player or maybe someone completely random pulling the strings from the dark. Everything was possible and he can't deny any of those possibilities without proper evidence.

However, today, after checking on the partner of justice, he got the missing piece of the puzzle to connect those events.

At first, when he arrived in this world, there was a hacking in the Holy Grail System, which allowed this war to become a 14 servants battle.

Leo knew from Assassin's mind that the players were the ones that hacked into it and got 5 pairs of command seals to summon servants. But what shocked him was someone stealing their servant, Pale Rider.

Someone stole Pale Rider and made him attack players with command seals before sending him to kill Enkidu.

From Archer, Leo heard that Alaya detected a disconnection from the Human Order in Matou's family during the Fourth Holy Grail War(Fate Zero) before it was corrected immediately.

Merlin also talked about the distribution and how it was close to Lancelot during the fourth war, which means Matou's side. Moreover, Avalon wasn't in Shirou's body and it was taken a long time ago before it was given back temporarily yesterday night.

Cu Chulainn found something in Matou's resident when Assassin was tracking him, which pull the attention towards Matou again.

Leo thought of checking on them, but because everything is happening and the fact they aren't in their residence, he had better things to do.

Now, Rin said that Matou Shinji, who is a waste of a magi, became a first-rate one. Not to forget her sister, whose hair is supposed to be purple became black.

Matou Shinji, who is incapable of performing sorcery because of Matou bloodline training, isn't even a magi in the first place.

Matou Sakura, Rin's sister, was supposed to be adopted by Matou's family, which transformed her element affinity to water via a painful and hellish process of insect's magecraft, so her hair color changed from black to purple.

Well, it's one of the unfortunate events that happened in this dark world. Leo as Satan and Beast VI, can tell you now that what happened to Sakura isn't the worst thing in this world.

There's a ton of things worst, even far worse happened to people in this world, and you say why he doesn't like the current humanity at all.

To be honest, Leo thought of a lot of possibilities. Like a system user to traverse into this world and join Matou's house, save Sakura, kill Zouken, summon a servant, etc… A lot of things that every reincarnator does in this world, but Shinji? Traversing into Shinji's body? He has to admit that he didn't think of that one.

{Note to self, expect more unexpected in the unexpected. Don't think outside the box, but shoot it into space and think from there} Leo gave himself a small reminder for the future.

"This... Shinji is really something" Archer said as he was also surprised by this development. For someone to fool Alaya in the aspect of humanity. He doesn't know if he even should call him Shinji anymore.

"Indeed, 10 years hidden system user" Leo frowned because this was one of the worst developments possible. A system is a trump card that can create trump cards. He can't imagine how many cards Shinji has in his sleeves.

"Then Medea should also be the Caster from the fourth Holy Grail War, and survive until now like Gilgamesh" Leo looked at Merlin because he knows that he has some of Medea's mana, which can be used to track her.

"Do you want to track her? I need to be at a certain distance to work" Merlin said, which made Leo shake his head before he said " I was thinking, do you have any idea why 'this' Shinji actions are all over the place?"

Sending Pale Rider to kill Enkidu during his battle with Gilgamesh, Medea and Lancelot to steal Cu, and giving Emiya Shirou Avalon back to save him before taking it again. Is this a high-level IQ play or something completely stupid, which he can't see through?

"Maybe he wants something with his actions… But most of them are vague or he's just doing things randomly" Merlin shook his head as he was also thinking about the current events.

"Eliminating servants? Obviously that the first goal of every master in this war" Nero raised her eyebrow as she stated some obvious things.

"If he wants to do that, he can just gather his servants and get the advantage of number" Archer shook his head as he denied these casual attempts from someone hidden in this dark world for more than 10 years.

"Maybe it has something to do with the chain of heaven?" Ritsuka said because Enkidu's abilities can be fatal on certain enemies and it might pose a threat to this newly discovered enemy.

The group was thinking about why the new Shinji is throwing his servants around while forgetting someone.

"..." Rin was bewildered while looking at everyone discussing Shinji's subject like he was a final boss or something.

More importantly, her sister is with Shinji, which means she is also participating in this war. She knows her sister's attitude towards Shinji, so she can't think of another thing that will happen.

And now, this group is clearly aiming at him, which includes her sister.

"Okay, let me get this straight, you wan-..." However, before Rin finished. Merlin and Leo realized something before they said " Angra Mainyu"

The completely random name confused the people around, however, before they explained their great wisdom to the others, Leo and Merlin flinched because they felt something weird in the city.

"Rejoicing priest?" Leo's expression became weird again when he saw something with his Clairvoyance, or nothing because Kirei's location became a black screen now.

Leo didn't wait for them to understand as he clapped his hand and said " Rejoice, everyone. Who wants to go to the church with me?"

Satan, with his flesh, blood, and mana actually offered someone to go to the church with him as an awkward silence filled the place.

Kirei, who was in the church, felt a sudden chill as he didn't know the source for it, however, without anyone knowing, a red blood was in Fuyuki's sewer system as it was extending towards the whole city while moving in the church direction.

Meanwhile, 'Shinji' and Solomon were facing each other as they didn't show any particular expression for this event.

"I assume yo-..." Shinji wanted to continue the conversation, but Solomon raised his arm without a warning and shot a huge beam of light at him.

A direct sneak attack without even giving a crap about everything else. This is Solomon in his rationality mode.

The beam of light carried a huge amount of heat while flying towards Shinji, however, he didn't show any care about it.

The beam, which is a partial release of Solomon's third Noble Phantasm, started to become smaller and lose power during its flight towards Shinji. In less than a second, the beam became a spark as Shinji extinguished it with his fingers.

"I guess you aren't friendly, huh" Shinji shook his head before he said " But I think that obvious because we are aiming for the same thing"

"...." Solomon didn't respond to Shinji because he knows that Shinji is delaying the time for some reason, but he is also taking advantage of that to analyze the situation.

"However, now I look at you. No wonder Beast VI chose to attack you despite all other choices" Shinji smiled at Solomon, even if his words carried a lot of sarcasm.

"Alchemy… No, it's something else" Solomon's golden eyes lit up slightly before he looked at Shinji and whispered one-word " Origin"

At that moment, the smile on Shinji's face faded a little as he waved with his hand towards Solomon.

Solomon took a step to the side as something passed next to him before looking at a deep cut that extended for more than 1 kilometers in this reality marble.

"An attack for another, right?" Shinji said casually as Solomon's expression didn't change at all.

"The flow has changed..." Solomon whispered those words, which made the expression on Shinji's face become colder.

The atmosphere of war was boiling in this reality marble as the third day of the Holy Grail War had officially started.
