Rei walked next to Archer as Eve was talking to Rin and Emiya.
"So sensei, tell me. Why do you persist on amnesia when I could tell that you know about the ability I used." Rei said sitting down. Snapping his fingers he isolated the space before gesturing to Archer to talk.
*Sigh
"I'm sure I don't know you and how do you have my personal ability." Archer said serious.
"Well I suppose I know you from a different world. Not the current you but a parallel you if you would say." Rei said looking out to the city.
"That still doesn't explain how you have the ability." Archer turned towards Rei.
"The ability is like a inheritance I suppose, but I should tell you now that killing your present self wont change anything you know." Rei said breaking the news to Archer.
"What do you mean?! Wont killing the cause change the effect!" Archer said frowning.
"No, the throne of heroes is a databank of all the information on heroes. When they are summoned, their data is copied and pasted into the world. Even if you kill your past self, your data gathered from a different timeline has already been stored." Rei said shaking his head.
"No....YOUR LYING!!!" Archer said in denial.
"I am really sensei?" Rei said looking at Archer.
Seeing that Rei isn't lying, Archer sat back down in defeat.
"So I can't be spared of this..." Archer said as he lost his wish of being freed from the throne.
"Not entirely." Rei said rekindling the hope in Archer.
"What? Is there another way?"
"Yes but I can't do it yet. I'll need this grail war to end first, I can then use the energy being returned to the throne to track down the location. With that I should be able to destroy a part of the throne releasing your 'Data'/contract and you should be free." Rei said telling Archer about his plans.
"Why are you telling me this." Archer suddenly said not understanding why Rei would do this even if in he had apparently trained him for 10 years.
"Well, I can't say i'm a good guy so let's just say because it's interesting." Rei said smiling.
"You see, I already know the way this timeline will go, so I thought I'll change it up a bit. Join in the summoning, kill a few trash masters here and there. And maybe take the throne of heroes for myself." Rei's smile grew wider.
"And here I thought I was fucked up...." Archer said looking at Rei.
"??? What do you mean?" Rei said not understanding him.
"You've lost your entire regard for human life or most things for that matter, you only do things for fun now...." Archer said as he walked away.
"Huh.....And what about it?" Rei said not bothering.
Archer turned around shocked at what Rei said.
"You see sensei, Eve and fun are the only things i'm interested in anymore. Pair that with 130,000 years of seclusion resulting in a disregard for most things and getting your nihilism, we then get my current self." Rei said with a smile and a shrug.
"And your fine with that?" Archer said frowning.
"Yes I am, as long as I have my two main interests i'm fine." Rei said accepting how broken he was.
Silence carried on as Archer stared at Rei while Rei looked at the city.
"Hey! Archer, Rei! We're heading over to see the fake priest do you want to come?." Rin shouted towards them as they prepared to head over to the church.
"Hm? Sure." Rei said as he jumped down landing next to Eve.
Archer only looked at Rei with a slight frown before disappearing.
It didn't take long for the group to reach the church as Saber decided to stay outside and keep watch.
"Why do you suppose Saber won't come in with us?" Emiya asked seeing Saber stay outside.
"Well she did say she was in this time period before, so maybe something happened between her and the fake priest here." Rin said as she walked towards the church.
Ignoring Emiya and Rin, Eve pulled on Rei's sleeve.
"Hey Rei, should we kill Kirei sooner?" Eve whispered.
"Hm....Sure, in this timeline he had a small roll after all." Rei said back as he dismissed the space.
"Rin, you have never accepted my repeated invitations, and now, here you are with three unsual guests." Kirei said as he looked back.
"I take it that one is the seventh master and the other two are the half servants?" Kirei continued as he examined Emiya, Rei and Eve.
"Talk to the seventh master first before us." Rei said as he and Eve sat down waiting for Kirei to explain the war to Emiya.
As Kirei explained the war, Rei was thinking about the command seals.
'The command seals work as soul seals. They take a very small portion of the persons soul before converting it into a seal. The person who uses the seal is able to bend the person affected againt their will. But it seems like the seals here allow for three commands....' Rei continued to think about the construction of the seal.
'Now then onto you two." Kirei said as he finished talking to Emiya. Rei stood up with Eve as they walked infront of Emiya and Rin.
"Let's cut to the chase." Rei said as he traced a few blades to float in the air and Kyoki in its first form in his hands. Feeling that they are real noble phantasms, Kireis eyes widened slightly.
'Gate of Babylon?!' He though shocked as the only one who has a similar ability is Gilgamesh.
"Kotomine Kirei, Master of Lancer." Rei said as he walked forward shocking the people behind him and Kirei.
"Die." Rei said as he disappeared from view.
"Lancer come!" Kirei shouted quickly in a panic.
Unfortunately, Rei was faster than the speed of summoning. 5 Blades including the Kyoki in Rei's hand shredded up the body of Kirei causing flesh and limbs to be thrown.
"You....." Lancer said as he finished being summoned. Swinging his spear at Rei, Lancer attacked only for Rei to pinch the blade with ease.
"Your current master wasn't a decent human so why attack me for him?" Rei said to Lancer.
"...." Lancer was silent as he knew that Rei was right.
"Well either way it is no use now. Would you like to stay in this world for now or leave?" Rei asked giving Lancer a chance.
"And how would I stay in this world?" Lancer asked looking at Rei.
"Become my servant." Rei said simply.
"I refuse, just kill me." Lancer said as he didn't want to be beneath Rei who didn't warrant his loyalty.
"As you wish." Rei said as he cut off Lancer's head.
"Why did you kill him!" Emiya shouted as he saw Rei kill with ease.
"He was dead to begin with. By chance he'll probably be summoned again in the future." Rei said as he walked out of the location without worry of what he just did.
Emiya could only watch Rei and Eve walk away.
"Rin chan, you should know that Kirei was also the one who killed your father. How we know? We know the what happened in the 4th grail war." Eve said helpfully to Rin while they passed her, Rin's eyes widened at the realisation.
Walking out, Rei sensed Berserker near by.
"Hou...I do wonder what it feels like to challenge a demigod." Rei said with a smile.
"You know that with your power right now, demigod or not. He will still die you know." Eve said.
"Of course, but I want to see how a so-called demigod matches with me right now...."
