Even though Angra Mainyuu already been sealed by Adult Rin. The darkness that lingering around the All World Evil wasn't sealed along with Angra Mainyuu because the darkness was had a chance to escape a moment before Angra Mainyuu completely sealed. And the darkness was itself are hiding inside the shadow of Shirou without him knowing about it at all.
But there is one thing that the darkness was expect at all. And that thing was there was something that more terrifying and more dark than the darkness it self that already staying inside Shirou shadow, something that only would active if someone was trying to tainted Shirou soul with a pure darkness.
Something that was prepared by Shirou real parent just in case something bad are happed to Shirou. But to active the protection there are condition that must to follow. First Shirou mind must be healthy and didn't have any obssesion to something or evil intention to anything lastly the protection can only protect Shirou soul from being tainted if his soul and mind already being tainted with unhealthy obsession to something or he have a darkness inside his heart then the protection cannot be activate and Shirou cannot be protected by it.
Almost every Emiya Shirou in the multiverse have that protection but because almost every Emiya Shirou in the multiverse was fall into a darkness because of his stupid obssesion to became a Hero of Justice and saving everyone in the world alot of Emiya Shirou in the multiverse cannot activate the protection. The Shirou who going back to the past was lucky that he already let go of obsession for the sake of his love to Sakura and to save her from the darkness. And because of that he can activated the protection even though he doesn't realize at all.
Right now the thing inside his shadow was consuming and absorbing the power that the darkness have. And slowly and steadly the thing was starting to evolved and awakaned the sleeping consciousness that already sleeping for a very long time.
And when the consciousness awaken fully Shirou would got a power beyond what he cannot imagine. And he would have a power that on par with his two other self that was living in the dimension that free from Gaia or Alaya.
Inside Shirou shadow...
"To put a lot of copy of me in almost every version of his son, that houjitsu user was really insane. How he can achieve that was beyond what can I think of more rightly more than I can capable of. But because I have a job to protect his son from any harm then I will do the job because I cannot denied the order from him. Beside that if Emiya Shirou die, I also would die even though I only a copy of my original self that doesn't have a full power of the original but as long as I have all the abilites of the original even though it only a weaker version. That was more than enough for me."

"Fyuuh because we already sealed Angra Mainyuu one of our problem already solved, and now what we must do is waiting for my husband to kill Gilgamesh," Adult Rin said who feel relieved that she can get her job done succesfully. "Even though I my self didn't know how long the time that my husband need to kill the King of Heroes."
"Gilgamesh was insanely strong so even though Archer are having a very good chance to kill that bastard. I think it would difficult for him to kill that arrogant King," Saber said with an angry look on her faces because she remember the hard time that she got when she was fighting Gilgamesh. "If I have an unlimited amount of magical energies then I my self can beat him by using a rapid energy blast, from Excalibur!"

"Eh, Saber, aren't that was too much?" Asked Shirou who questioning the sudden brutality that appear on Saber.
"If the enemies was that goldy that kind of attack was the most proper attack to kill him," Saber replied while sparking an angry aura from her body.
"Yeah, but infinity magical energy can only be achieved if someone was having a True magic like Zelretch or Emiya-kun," Rin said while sighing. "Because Zelretch the wizard marshall can open a portal to a parallel world and then gathering infinity amount of magical energy from there while Emiya-kun can just the Denial of Nothingness to
make a magical circuit that act like a nuclear reactor so that he can have endless magical energy or atleast a very big magical reserve!"
"Eeeh, I cannot make something like that, Tohsaka, I didn't know how nuclear reactor was working! So how can I make a magic circuit that act like a nuclear reactor!" Shirou said with a confused look on his faces. "It was impossible for me to make it!"
"You don't have to worry about that Emiya-kun, because I will make sure that after the fifth Holy Grail Wars ended completely I will force you to learn alot about physics and nuclear theory so that you can make the new magical circuit for me, you and also Sakura," Rin said with a greedy look on her faces.

"Ne-Nee-san your faces was look very scary," Sakura said whose faces are became pale right after she saw Rin greedy look. "Please back to your usual self!"
"Your sister was right Rin, you look like a greedy demon right now," Saber said who doesn't like the look on Rin faces. "please stop being greedy like that!"
"My younger self was more greedy than me because she having a money problem, huh? Unlike me who have an alchemy to make infinity amount of a gold or jewel so I didn't have any money problem at all," Adult Rin said who feel a bit sad seeing her greedy younger self. "Well but her idea by making a new kind of magical circuit that act like a nuclear reactor was very interesting, theoraticly it was not impossible to achieve at all as long you have the right tool to achieving it. And that tool was Denial of Nothingness."

"So you damned faker you would be the one who fought me, huh?" Gilgamesh said while wearing his golden armor. "Did you think that you are strong enough to beat me, mongrel!"
"I maybe not as strong as you in the term of raw power Gilgamesh," Archer said while already tracing Kanshou and Bakuya. "But this is not the first time for me fighting you. Because in another timeline and in another Fifth Holy Grail Wars I already fighting againts you for a countless time. So by using the experience that I have fighting you, I think I had a chance to won againts you."
"So you are a trype of Servant that remember the experience that you have in a Holy Grail War huh? That type of Servant is very rare," Gilgamesh said who feel a bit surprised when he heard Archer words. "But let me guess, you never win againts me even once right in your countless experience to fight me in every fifth Holy Grail Wars."
"Sometimes I lose, sometimes I fight evently fighting you and everytime I had a chance to beat you. That bitch Alaya disturb me and summon me back to the Throne of Heroes," Archer said with an angry look on his faces. "Alaya don't want me to win againts you, because if I beat you then I can become a Transendence and then free from Alaya grasp. Because one of the hidden condition for me to free from Alaya was to beat the strongest Servant in the throne of Heroes. In other words I must to beat you. I took me a very long time to realized that beating you was mean that I can free my self from Alaya."

"Sadly it's too late for you to realized that thing," Gilgamesh said opening a lot of divine gate that surrounded Archer. "Because today was the day you will be back to the Throne of Heroes and became Alaya lapdog once more!"
A lot of Noble Phantasm was coming out of the Divine Gate and shoot out to Archer with a super sonic speed. Fortunately before Gilgamesh was opened the Divine Gate, Archer already changing Kanshou and Bakuya with Ensui and then he making a Mizu kugutsu by using the water that he collected in the air using Ensui power.
All the Noble Phantams that shoot out to Archer was stabbed into the Mizu kugutsu that replaced his real body. While Archer himself was appear behind Gilgamesh and then stabbed the back of his golden armor using a Noble Phantams that strong enough to destroy the protection from the Golden armor.
The spear that he used to destroy Gilgamesh armor maybe not having a special power like Gae Bolg. But the spear was very sharp and if Archer was reinforce it using magic power the spear was more than enough to penetrate the defense of Gilgamesh armor.
