Day 0

**Day 0** (A World Without Gnosia) is a Setsu event. Day 0 refers to the day when in the universe Player and Setsu comes from, Player gets annihilated by the Gnosia, and thus occurs one day before the Day 1, the usual starting point of a loop. The two hosts of the Silver Key manage to go back in time to the Day 0 only by transferring to an alternative universe, where no one from the crew gets infected by the Gnos before entering D.Q.O., and so, the Player from this universe, who doesn't have the parasite, is still alive. Unlike the prisoner of loop, they got injured during the evacuation from Liu-An, and so they are in a pod in the Sickbay to receive medical treatment when Setsu and their ally arrive.

An encounter of the two alternative Players results in inconsistency, that causes the whole parallel universe to get destroyed due to the overlapping existence of the very same person. This leads to allowing the hosts of the Silver Key to start their loops only at Day 1, in an universe, where Gnosia is onboard the ship.

## Script

[player]: This place...

Setsu: A universe beyond the reach of the Gnosia. The only universe in which not a single crew member is infected. [player], so you made it here, too. To this... world of yesterday. That's right – this loop begins one day before our usual starting point. I don't know why, though. Alright, [player]. Let's see what happens...

**Day 0**

Comet: Hey, [player]! You're awake. And Setsu, too, huh? Everyone's eating in the cafeteria. You two wanna come?

Setsu: Oh, uh... Sure, thanks. Let's go check it out, [player].

**– Cafeteria –**

*The table in the cafeteria is covered with all different kinds of foods.*

Chipie: Hey, [player] and Setsu are here. Sit down and have a bite.

Shigemichi: Hey, Setsu! I wanted to say thanks, actually!

Setsu: Hm? Did I do something to be thanked for?

Shigemichi: What're ya talking about?! You saved us, bud!

Comet: Yeah! „Liu-An”, was it? That planet was full of Gnosia! If you hadn't led us out, we would've been annihilated.

Gina: Yes... thank you, Setsu.

Setsu: Oh yeah... Hehe, I guess I did, huh...

Sha-Ming: Even I'm grateful for that, ya know? My appreciation just kinda morphed into desire, is all. You know what they say. Something about a drowning man grasping at straws or whatever?

SQ: Hey, Setsu... Maybe you should've, like, not save Sha-Ming, too?

Setsu: Seriously.

*Everyone is eating and talking pleasantly. Even Setsu flashes a smile here and there...*

Gina: [player]... Are your injuries healing alright?

[player]: Injuries...?

Chipie: Oh, yeah, [player], you did get banged up real bad, huh?

Comet: Yeah, it was pretty terrible.

Shigemichi: I was sure Dergy was gonna end up lookin' like me...! Anyway, glad to see you're OK, bud! Here's to you, my man!

*After staying around for a bit, you and Setsu leave the cafeteria.*

Setsu: [player]... I had no idea you'd been injured. But.... everyone else seems to know about it. It's not just that there Gnosia are not here. This loop seems completely different from the others. Also, hehe, it's strange.Till now, everyone has been suspecting and lying to each other... It's strange seeing them all getting along together like that.

Setsu: …

Setsu: If... if we keep on... Sorry, never mind. Let's go, [player]. We should talk to the rest of the crew, too.

**– Main Control –**

Raqio: How many times must I say this? Setting course for Gliese is clearly the most efficient way to go. Why can't you understand this?

Remnan: Raqio... that's enough, OK...?

Jonas: But I – JONAS! A captain of this ship, say that... Ah! Hehe, speak of the devil!

Stella: Hm...? [player]...?

Jonas: Setsu, we were just discussing plans for the future of this ship. As you have ties to the military, let me ask... We, having escaped from the Gnosia-ridden Liu-An galaxy, are refugees. And it would appear that there are no other survivors. Therefore, our duty is to report the status of Liu-An to the proper authorities. I submit that we should head for Oudan Base, which is not far from here, but...

Raqio: That's foolish. Who knows how long we'll be held up with reports and examinations if we go straight to the military...? I cannot abide this.

Jonas: As you can see, this is where we now stand. Setsu, your thoughts on the matter?

Setsu: I see...

Otome: Yeah, I think Setsu should decide for us. We don't have to fight like this...

Kukrushka: [Kukrushka nods in agreement.]

Setsu: I'll submit a report on the situation in Liu-An. So we won't need to go all the way to the base.

Stella: Is this acceptable...? According to the interstellar travel rules, when Gnosia infection is discovered, it must be reported immediately to...

Setsu: It's fine. As long as we know nobody onboard is infected, we can ignore the rules.

Raqio: Haha, what a surprise! Setsu, you've got quite the head on your shoulders.

Jonas: Hmph... Understood. In that case, we'll head for Gliese, as Raqio wants...

Remnan: Great...! Thank you, everyone. Also, Raqio...

Raqio: No need to thank me. I just want to get back on Gliese quickly.

Remnan: No, I... I know. It's just that, if we go to the base, then I'd have to see... uh... Anyway, thank you for thinking of me, Raqio. Many of you seem to misunderstand this, but Raqio is... actually a very good person.

Raqio: I'm sure everyone here would agree. Remnan, you're crepping me out.

Remnan: …

Otome: Um... Jonas? If we're going toward Gliese, I'd appreciate it if you could drop me off on Planet Nada along the way. My home is on Nada, so...

Jonas: But of course, that will be no problem. Hehe, 'tis a gentleman's duty to escort a lady, after all.

Otome: Yay! Thank you! I wonder how Dr. Yoshikado is doing...

Kukrushka: [Kukrushka smiles at Otome, as if to say „Good for you!”]

Otome: Oh yeah, Kukrushka! What will you do from here on?

Kukrushka: [Kukrushka waves her hand slowly.]

Otome: …

Setsu: Otome. What did Kukrushka say?

Otome: Um... she says she hopes to get some sleep, wake up, and just have fun till she dies.

Setsu: Oh, I see...

Otome: \*SQUEAK! Oh yeah! Kukrushka, would you like to come to Nada with me? I'm sure you'll be able to make a lots of friends there! What do you think...?

Kukrushka: [Kukrushka simply smiles quietly...]

Setsu: „From here on”, huh... We've got a future ahead of us, don't we? Hehe, I had sort of forgotten. It's something that was always out of my reach. So, [player]. If we're able to stop the loop... I want to stop the loop here, in this world. In this world without Gnosia. In this world, we all have a future ahead of us...

Yuriko: But, [player]... You have no future.

[player]: Yuriko...?

Yuriko: Do you know why, [player]? Because you're something that should not exist in this universe.

Setsu: What's wrong with you, Yuriko? Why would you say...

Stella: No, Setsu. Yuriko is correct.

Setsu: Huh?! Stella, you too?!

Stella: When we escaped Liu-An, [player] was badly injured in an accident. Since then, we've been providing treatment in the medical pod, but...

Setsu: The treatment has finished, and now here we are. That's all, right?

Stella: But...

Yuriko: Hmph, Setsu. Of course you don't understand with just an explanation. See with your own eyes.

Setsu: Fine... Let's go check the medical pod, [player].

**– Sickbay –**

Setsu: Here it is... There is someone in this pod... The status reads... „In Treatment”. It looks like it's almost complete. Let's wait here.

Setsu: …

Setsu: To be honest, I'm... scared. But... Do you remember? „Don't doubt. Don't be afraid. And know. Knowledge will save all.” You told me that, [player], long ago. And I agree. We must know.

[player]: But... That was what you had said to me in the first loop...?

Setsu: Huh...? You... you don't remember...? Ah, I see... Heh, hehehe. I get it. No, it's nothing. Never mind. More importantly, look... It looks like the treatment is complete. The pod... it's opening up... [player]... [player], if you were... Whatever you may be... I will...

*Inside the pod was... Another „you”. And then... The instant the eyes of this other „you” open...*

**Due to a fatal error, this universe has been annihilated.**

[player]: I can't see anything. Just what is...

Setsu: This world is terribly unstable. Apparently, we ended up here due to the disappearance of the universe. I don't think it will hold out very long. This could actually be a good opportunity... Let's talk and gather our thoughts. In that last loop, the world without Gnosia, there was one more „you”. So... what exactly does that mean \*you are? Are you the real [player]? A clone? Or possibly... a fake, posing as [player]?

- - > The Real Thing

*You answered that you're the real thing.*

Setsu: Yeah... You, and one more „you”. Both are the „real” [player]. That's what I think. Overlapping existence caused inconsistency, which in turn is causing pair annihilation. This is likely what caused the universe to disappear.

- - > A Clone

*You answered that you may be a human clone.*

Setsu: So that's what you think? I see... Wait, but you don't have any memories, right? Listen to me... Considering the timing... You, and the other [player]... This double existence caused inconsistency, causing pair anihilation. This may be the cause of the universe disappearing. Therefore... I think it's safe to assume that you're the "real" [player].

- - > A Fake

WIP

Setsu: In that case... Then, the universe of the loops you've experienced up to now... Was there another [player] there as well? What do you think?

- - > Yes

*You answered that there probably was.*

Setsu: Hm. So, that means... Just as Raqio said, there was one more [player] onboard this ship.

- - > No

*You answered that there probably wasn't.*

Setsu: The universe as we knew it hasn't disappeared. So, there wasn't one more [player]. Maybe, but... Try to remember. What Raqio said before. That there was one more [player] onboard the ship.

Setsu: And  so... what happened to the „other” [player]? Raqio spoke about this as well – do you remember?

- - > They Disappeared

*You answered that Raqio said they disappeared.*

Setsu: That's right. They disappeared, before we awakened after looping back.

- - > I Forgot

WIP

Setsu: In that case... who erased the other [player]? So, if the other [player] was erased... Who do you think did it?

- - > Gnosia

*You answered Gnosia.*

Setsu” Exactly. The Gnosia onboard the ship erased the other [player]. Because of this, with you and the other [player]... The problem of this overlapping existence hadn't previously occurred. But without anyone infected by Gnosia... the universe disappears. That's why up to now we were only able to loop into a universe with Gnosia present. That was the only universe in which we'd be allowed to exist.

Setsu: …

Setsu: Listen, [player]... I thought of something when we were in the universe with no Gnosia onboard. If possible... In that universe... Where nobody would have to be sacrificed, where we all had hope... I wanted to end the loop here. So... [player], the „Key”. We need the „Key” to solve this. The „Silver Key” needs to be filled. Gather as much information as you possibly can. Information we don't yet know, about everyone onboard, everything... If you can do that, then I'm sure... [player]...

**This universe collapsed.**

### Day 0 - Unfilled Key

There's alternative dialog if the player attempts to re-visit the world without Gnosia but lacks some of the Notes.

## Trivia

* If the player checks the status menus during the segment where the world has collapsed, they'll be glitchy. The character status menu will be filled with Setsus of various status that change every time the menu is brought up, though it seems the Setsu closest to the player will always be alive. The parameters in the loop settings menu, meanwhile, will constantly and rapidly change.
