We've got a boot strap paradox here Setsu gave Yuri the silver key and Yuri gave Setsu the silver key, so who got theirs first and how?

I thought the silver key was going for the obvious opening to avoid the double existence find a world in which either Yuri wasn't born or dead and not on the ship. We see worlds where others weren't there why not real Yuri.

Others weren't there because they don't make it onto the ship, not that they never exist. Original Yuri dying is the fixed point for the ship now since that is the originally how people knows there is a Gnosia on board even before anyone gets the Silver Key, so original Yuri would always be there.

We don't expressly know why they weren't there and no one mentioned that so and so didn't make it aboard so we can't say for sure. Original Yuri wasn't how people knew about Gnosia the ship scans for them and as we've seen in the past couple of episodes the original Yuri doesn't have to die which became the problem. So there are worlds where Yuri dies and worlds in which he doesn't, worlds in which some people are around and worlds in which people aren't, we also have other things like SQ and Kukrushka having a different person inside them, as well as worlds with no Gnosia onboard. So with all these variances and the silver key the dimensional hopping parasite opening something for the person who filled it, finding a world where Yuri either died, didn't make on the ship, or wasn't around be on planet or born seem possible.

We know Jonas mentioned Kukrushka and Yuri deduces that in some world lines she just doesn't make it onto the ship, they specifically do mention people that aren't there simply because they don't make it, not that they don't exist. The DQA is always Jonas's ship.

No, like we see in this episode, everyone getting into their room so the ship could do a safe warp, the fact is simply because there are no Gnosia on board so original Yuri gonna live but it makes the universe collapse from 2 Yuri existing in return. When there is Gnosia in board, original Yuri has to die during the warp before Day 1, which help the warp scan and caused everyone to know there is a Gnosia on board because of original Yuri's death, in episode 1 when Yuri starts their loop, original Yuri already get attacked. There is no way to change this. It is already like that. It is either 2 Yuri world line or Gnosia world line.

In world where original Yuri lives and no Gnosia on board, it makes the universe collapse. Some people just don't make it onto the ship in different world lines. Kukrushka and SQ is simply because of Manan's past choices (which is still in character) because Manan controls both of them but their bodies still gonna make it onto the ship or not.

So no, the Silver Key can't do that. Original Yuri needs to always be there on the ship, which Gnos creates Bug Yuri's body to replace the original Yuri in the first place. Which is why Yuri is a Bug, they aren't supposed to exist but they do exist, their existence needs to be on the ship.

We know in that one instance which makes sense since Kukrushka is with Jonas and exists because of him. If they aren't on the ship and it's not stated it could be for a number of reasons like not making it, dying before hand, not being on world we don't know. Jonas, Kukrushka and Stella are the only ones we can say with any certainty are on world because as you said it's Jonas' ship and he is the reason Kukrushka exists and Stella is part of the ship.

We see in this episode that Yuri wakes up goes to the room that the vote normally is in where people are discussing what to do, the topic of a Gnosia being onboard comes up and Setsu specifically asks the ship if any are on board and the answer is no. This happens on day 0 before they even take off, so no it doesn't require someone dying first.

I'm not saying Manan being one of them is out of character I'm saying it's a past action causing a variable in the present, because that's what this is about changes and variables in which the pasts of character including who they are if they make it or even if they know each other changes between lines. Manan doesn't control both of them only 1 and even that's a maybe. SQ is priority but if that fails the Kukrushka but we also don't know it that's always the case. Without confirmation we can't tell if Manan is either of them but she can only ever be one of them.

How is it you get to say what the key can and cannot do? We see that Gnos creating the bug isn't always consistent so why is the original being there? Gnos had bug Yuri take original Yuri's place in the pod but when the original was still there the bug simply was displaced into Yuri's bed and in this episode Yuri ended up being taken back to before he existed since bug Yuri was made on day 1 but the silver key took him to day 0. So the silver key has shown the ability to displace bug Yuri outside his normal space and time so why is this outside the realm of possibility?

We already know all of them exist, they simply don't make it onto the ship. The anime states to our face that Kukrushka doesn't make it onto the ship, not that she never exist in world lines she isn't there. If we follow you, why couldn't the Silver Key jump to world lines where Jonas never met her? Because it wouldn't, the Silver Key wants their backstory in their characters.

No, Yuri wakes up in their own room then run to the voting room. Everyone already going into their own room and the ship does a safe warp. If there is Gnosia on board, original Yuri would already be dead before Day 1. It absolutely needs someone dying if there is a Gnosia on board.

The Silver Key can't make them act out of character because there would be no informations in world lines where Raqio is a dictator or Stella is Skynet. The Silver Key won't go into world lines where they don't exist. Manan controls both of them, they are her or not depends on her choices.

Because that is what the anime says. Gnos creates the Bug is consistent. What? Original Yuri is victim no1 before Day 1 happen in all world lines with Gnosia on board, because once Yuri starts looping original Yuri is already attacked before Day 1 in episode 1, it can't be changed. Gnos only creates Yuri's body specifically to replace original Yuri because the Silver Key jump to these world lines but Gnos doesn't expect original Yuri still being alive in these Day 0 world lines as original Yuri always get attacked, Bug Yuri is only created because original Yuri is on the ship in the first place, if there is no original Yuri then Bug Yuri wouldn't be there. No, original Yuri was attacked before Day 1, that is why the meetings always happen on the start of Day 1. That is not outside normal space and time, it is within Yuri's space and time. Nothing can change that original Yuri is always on the ship because they are why Bug Yuri is there in the first place. It is either 2 Yuri existing or Gnosia on board world lines.

We know in that instance that's what happened, and it wouldn't state if they weren't there or didn't exist because that's proving a negative, no one is going to say, 'this person that never existed isn't here,' because of the simple logic of they can't. We also aren't seeing this from an omniscient position so if they weren't alive or on planet we would have no way of knowing, so you're simply using one case and then using a negative as the affirmative aka no one said it didn't so it must be.

For Jonas and Kukrushka that is a terrible example he had he built she wouldn't exist if Jonas didn't so in no universe could they not meet. A better example would be Comet and Chipie since he's the reason why she's there but not the reason she exists. We do also have an example with Jonas and Kukrushka showing that not everyone has always met, when we had female Yuri he asked Jonas about Kukrushka and he words were, "I never introduced you to her," causing him to become suspicious.

The haven't even taken off before the scan happened they are literally talking about whether or not to take off this is on top of it being day 0, Real Yuri dies on the transition from day 0 to day 1 as it is with all others it's during 'night' just like the game it references werewolf. You can't have them talking about taking off after going through a warp jump.

You have no proof about any of that just an absence of confirmation, we don't know what's going on with them when they aren't on aside from anytime it's mentioned. You are correct it can't change personalities it only has the ability to change where in time and world line the host is but it can go to timelines where they don't exist unless you can show me something to the contrary. From the sounds of it Manan doesn't make the choice if she's SQ or not since SQ says that something went wrong and that's why she isn't Manan so Kukrushka is plan B meaning it's out of her hands.

You do know that only this one was day 0 right? the others with the universe destruction loop was day 1 the day 'Yuri' always wakes up form the pod. As stated original Yuri is attacked on the 'night' of day 0 going into day 1 so bug Yuri is made at the start of day 1 so him being in day 0 before Yuri was attacked since the Gnosia can only attack during a warp and they had yet to take off they literally couldn't have attacked Yuri yet in any timeline. This is on top of Yuri being displaced spatially both in the double Yuri day 1 loops and in the day 0 loop he was in his bed not in the pod.

As far as where the silver key would take him Yes it was aiming for information which it got from backstories however what I'm talking about is once it is satiated and moving on from Yuri that qualifier goes out the window since it's not taking in more information, that would be like being full but choosing the restaurant someone else is going to. I'm saying that due to multiple worlds theory which this uses any world that is possible exists so a world in which there isn't an original Yuri on board must exist and it could have taken him there. Narratively it would have been better as well because Yuri started not knowing anyone but everyone knew him now thanks to the silver key he knows everyone but without an original Yuri no one would know him it would be narrative symmetry.

Let's pretend that is the only case. So what? That meant the only evidence we have is they simply exist but don't make it onto the ship and you have no evidences that they don't exist. In fact, the only evidence is they exist, they simply don't make it onto the ship. Yes, I can't prove a negative. I can just state the truth. The anime states the truth that they exist, they don't make it onto the ship. If you can't disprove this or prove otherwise then why even brought it up? Best case scenerio, you just say nothing. Fact of the matter is they exist, that is that.

What? Kukrushka is just a doll Jonas bought. If Jonas exist then Kukrushka could just not exist. But fact is she does, she just doesn't make it onto the ship sometimes. Chipie is the reason Comet was on Liu-An. But Comet could just ask another driver to smuggle her out even if we follow you. World lines are infinity after all. But that is not the case. Everyone never meet, in episode 1 everyone says this is the first time they meet (other than special case like Jonas/Kukrushka/Stella or Chipie/Comet, etc). They exist, that is that.

....They already taken off when the scan happened, what? They literally speed up into space and only ask Levi when they leave the room again. Did you watch. "Day " just meant the time between warp, they call it for convenience, Original Yuri always get killed, everyone knows it and prepare for the meeting. There would only be "Day 1" if there is Gnosia on board. If there is no Gnosia then it would always be Day 0 since there is no werewolf, in fact Levi didn't even call it "Day 0", Yuri just calls it for convenience.

You didn't say any proof so you assume from nothing in the first place. I just repeat what the anime says and shows. "but it can go to timelines where they don't exist unless you can show me something to the contrary." No? I can't prove a negative. You are the one who need to prove or bring up statement that they don't exist. Bring me proof. While I actually have an example they do exist, they just don't make it onto the ship. Manan isn't SQ because it is an accident sometimes, but Manan becomes SQ is still her choice.

Yeah no. There is a reason why Comet feels like Yuri shouldn't be exist in episode 5, everyone knows Yuri is dead but can't remember. Everyone prepares for the meeting, they need to negotiate with Levi and choose a specific time to call it Day 1, then Bug Yuri wakes up, which meant original Yuri would wake up earlier than Bug Yuri with Gnosia board. There is no "Day 1" when the universe collapse. Original Yuri always get killed before Day 1 with Gnosia on board.

What does that have to do with anything. It is full meant it would leave Yuri in the first place and still jump to where it could stick to a host that get informations to continue its shenanigans. The Silver Key transfer consciousness so Yuri would still need a body on the ship, which couldn't happen if original Yuri doesn't exist on the ship. Original Yuri needs to be killed for another Yuri to go there safely. But there is no reason for Bug Yuri here to continue risk their life in another "Gnosia on board" situation when they live in a world where everyone is alive. If everything is possible then it can jump to a world where Stella is Skynet, might be it is possible, there are infinity worlds after all. But no, the Silver Key only transfer them to worlds where they exist and make in character choices (aka just don't make it onto the ship. Not "their parents never meet", that isn't how that works even if we follow you). So no, original Yuri must exist and be on the ship. It is either the universe collapse or Gnosia on board. It isn't good narratively, this original Yuri becomes Bug Yuri. Bug Yuri couldn't just let original Yuri doesn't exist. Yuri and Setsu make each other exist by Setsu helping this original Yuri starts the loop and Gnos makes a Bug body for them. Anyway, it is either the universe collapse or Gnosia on board world lines, that is that.

So in a series using the multiple worlds theory, involving hopping through both space and time, with mind swapping (Manan), gender swapping (female Yuri), seeing outside space and time (during universal collapse), a living doll that can predict the end of the universe (Kukrushka told Yuri the universe was going to end before he met himself) a priestess that can see outside spacetime and see other world lines and understand (to a limited extent) the will of an outerversal god, a boot strap paradox, and someone moving outside reality removing themselves from the current existence and rewriting the current history (Setsu taking real Yuri and going through the silver key door causing everyone to forget her but remember Yuri as the one that saved them) you think A) we've seen everything and B) that there are hard limitations based on the single perspective we've seen? (bug Yuri's) because that's what this comes down to what is possible and based on what we've seen I'm not putting anything outside possibility.

But if you want to think what we've seen is all there is feel free, it's a lot less interesting and I'm not sure that's what the author was going for but you have free will and can limit your imagination if you so choose.

Mind swapping (what does that have to do with anything, it is Manan's choice), gender swapping (Gnos creates Yuri's body and there might be world line where original Yuri's choice is to change gender so Gnos just does it as fit for the Silver Key's data. It needs to be in character), seeing outside space and time (because the universe collapse, what does that have to do with anything), a living doll that can predict the end of the universe (the reason is actually really simple and we will know) a priestess that can see outside spacetime and see other world lines and understand the will of an outerversal god (she literally touch the light of Gnos when Yuri's body is created so she knows why this is happening), a boot strap paradox (it makes sense, what does that have to do with anything), and someone moving outside reality removing themselves from the current existence and rewriting the current history (yeah so? Because they literally jump out of the world line).

"we've seen everything" yeah we do. Yuriko already says these are the only 15 people that could escape. The Silver Key wants informations on these specific 15 people so these 15 people exist and has a chance to escape onto the ship there shall be. There won't be world lines where Stella is Skynet because it would diverge too much from what is happening and what it wants, similarity, there is no such thing as "They never exist" when the Silver Key wants their informations.

"B) that there are hard limitations based on the single perspective we've seen? (bug Yuri's)", there might be world lines where Raqio is a dictator, we won't ever come to that world lines, it won't happen. Because the Silver Key won't jump to these world lines. It wants these 15 people. It is just how it works.

It is what is explained and how it works. If you think otherwise, it isn't my business. I'm just saying what it is.
