Gnosia

Saddled with amnesia, Yuuri awakens on an interstellar cruiser drifting through space. Unfortunately, a lack of memories is the least of Yuuri's problems. Among the four other crew members is a Gnosia: a Gnos infectee whose goal is the eradication of humanity. The Gnosia appears human in all other respects, so the uninfected have little choice but to vote on whom they suspect to be the enemy, hoping to neutralize the Gnosia by putting them into cold sleep. If the Gnosia survives the vote, they will eliminate one crew member during the cruiser's following warp, when only the Gnosia remains conscious.

Voting quickly proves to be an unreliable strategy, and Yuuri is left one-on-one with the Gnosia. Just when all hope seems lost, time seemingly loops back to when Yuuri first awakened. With each time loop, however, conditions aboard the ship change—neither the size of the crew nor the members' identities remain constant. Trapped in both time and space, Yuuri must figure out how to escape the loops and save humanity from the Gnosia.

Preliminary (3/? eps)

A surprisingly competent adaptation of the VN gnosia. It's based on social deduction game and it pours another mystery after another as you go through the episodes.

People might consider this as just another amogus rip off, but it's more than that. The loop itself is interesting because it randomly generated a new world or in this case "timeline," where the past differs from each iteration of the loop.

As Yuri progresses through the loops, they'll meet more characters and new roles will be introduced. It's far from simple. 3 episodes in and this is what people would consider the tutorial stage in the game. ... Yes, it hasn't started to get crazy yet. There's tons, and I mean tons of content to be explored and added. It's anything but repetitive.

It's definitely too 'easy' to guess who the Gnosia is in these earlier episodes. But could you believe it'll get more complicated, complex, and some might say 'convoluted' in future episodes?

Would recommend for those who crave sci-fi mystery with hot momm- I mean great design!

Mixed Feelings

Preliminary (6/? eps)

I'm calling a meeting, this anime is sus as hell. I just saw Gnosia come in through the vent and they're trying to convince me they're Kino. But actually, I can tell Gnosia is Mid from a mile away. So while I enjoyed the company of Gnosia to some extent, I still say it's for the best if we eject them out deep into space, never to be seen again.

Jokes aside, Gnosia is very...okay. While I'm happy to see a social-deduction game-themed anime, Gnosia feels like it misses a lot of the potential that it could have had. With shows like these, where they ... are meant to cater to a certain kind of person (deduction game enthusiasts), I'd say you would enjoy it more because you're already a fan of parts of it, but actually here I think it might be the opposite: I think the more you know about social-deduction games already, the *less* you'll enjoy Gnosia, for reasons I'll get into shortly.

First off, the good: I really like the colorful character designs, and while some people will be bothered by the psuedo-3D animation, I actually think it looks pretty good for what it is. Characters are very distinct from each other, which is an important part of any mystery story where you need to keep track of many different people. Sometimes characters will drop breadcrumbs of who they are or what kind of world they came from, which does a lot to make the world of Gnosia feel fleshed out and real. Characters will have their own strategies through which they play the game of Gnosia, but given the ruleset there's only so much a certain kind of person can do to make this engaging.

My main problems with this show come in two varieties: gameplay issues and story issues. Let's start with gameplay. In Gnosia, the main character, named Yuki, awakens on a spaceship and they are tasked with finding which one of the crew members is the imposter, otherwise known as the Gnosian. If you are familiar with a game called Town of Salem, the rules of Gnosia are basically identical to that game. And while I think Town of Salem can be fun in casual social environments, I think as a game it has serious issues that only become more noticeable when it's turned into an anime.

Town of Salem, as well as Gnosia, are games where the winner is effectively decided by who can lie the best. Games like Among Us also suffer from this problem, but it's exasperated here because there are absolutely no additional gameplay elements aside from meetings with the crew. There are no tools players can use or ways you can contradict stories people have told. In later episodes roles are introduced that add some complexity, but these roles still do not change the fundamental problem. There is absolutely no way to ever tell for certain when someone is telling the truth, because nothing in the game is ever verified except for the person accused of being the imposter after the fact.

This might not be an issue if the main character was actually capable of lying or otherwise competent at deductive reasoning. But Yuki is, for at least the 6 episodes I watched, so unfathomably stupid and bad at this game it is just agonizing for someone like me to sit through. I'm not claiming to be a genius, but there are so many moments where someone will say something crazy or revealing, and Yuki will just let it pass by without question. Their character has amnesia, so while being cliched it at least explains them lacking awareness, but regardless it's still frustrating to deal with. It feels like watching a show about Sherlock Holmes except the twist is that Sherlock is an idiot and the audience can do his job better than he can.

I also mentioned earlier that the overarching story is something I also take issue with here. Because when the premise is "Among Us the anime", you can either have one extremely long game for the whole season, or one game per episode, and they decided to go with the later. In order to justify this premise, Yuki is given the ability to timeloop into essentially infinite games of Among Us, which begs the question...why? What am I getting out of this as an audience member? What are the stakes?

Yuki is told that they need to do this to "gather information" over many loops, essentially mimicking the structure of a video game, but again, why? As an audience member I have no reason to be invested in any of this. Yuki, as a character, is quite boring and not particularly likeable. For all intents Yuki is just stuck in hell and if you like watching them play social deduction games forever I suppose you might have fun. But personally I found this lack of direction, purpose, or meaningful progress frustrating. The information being gathered is vaguely interesting, but none of it feels critical to me as a viewer, it's all very shallow.

I think a show like Gnosia can work, it just doesn't in this case, at least not within the 6 episodes I watched. Gnosia needs a better foundation; it wants to be a social-deduction anime without having the fundamentals of a proper mystery or suspense anime first. Gnosia never offers the viewer any "ah-ha" moments, because everything is vibes and nothing is certain. And while themes of trust can be interesting, it's also undercut by how unimportant and impossible it is to trust anyone when, not only do you have amnesia, but in a few moments the game will be wiped and you'll be starting a new game anyways, so who cares? Shows like Squid Games do a much better job exploring these themes than Gnosia does.

And for those reasons, I'm activating the airlock. Good luck navigating the vastness of space, Gnosia, hopefully you come back a better version of yourself some day.

Preliminary (3/? eps)

Premise: This show is Re:Zero meets Among Us, for toddlers. A bunch of people on a spaceship are trying to figure out who the Gnosia/body snatcher thing is. The MC has the-amnesia-trope (sigh) and is just not smart. The ship has an AI which knows that there's a Gnosia inside the ship (hold onto this clue for later) but can't pinpoint where.

Let me preface this review by saying it's becoming so hard for me to trust reviewers from TikTok, and I REALLY should know better. I saw a flood of comments on a fall lineup video asking, "Why isn't Gnosia on this list??" Me, being ... the ever-curious new fire-anime seeker, had to go see what these people were yappin' about. Side note: that particular list included Sanda as a top fall anime, and I should block them for that shit, frfr.

First: I didn't find the art that bad. It's colorful, it's enticing, and it's clean, although it's mostly CGI. It's not bad, but I guess anything compared to OPM S3 is going to be fire. SMH. I'm so heartbroken.

And... that's actually it. Seriously, that's all there is to this anime. Everything else falls to shit after episodes 1 and 2. You have to turn your mind completely off to get through this nonsense lol. But maybe it's not about the writing, plot or execution; it's about the brain tumors you gain along the way =D

If I can figure out how to solve the mystery of the Gnosia in the first episode, that's a fcking problem. This show presents plot holes as if... well, as if there is no war in Ba Sing Se—if you will.

For example: Two characters go out into space to do maintenance on the ship. The show explicitly states that the AI can tell if there is a Gnosia *ON THE SHIP*. Ummm, hello? Wtf are we doing here, chat?? This means the crew could use the process of elimination: send people out in space suits, while the other crew member(s)—wait for it—have the AI scan the ship from the inside! Genius, right? I know! But the show just glosses over this like it's not common sense! How anyone can give this a rating of 10 is beyond me.

And that's only one of the ways to solve the Gnosia problem. The show also lets us know that the crew has to vote for who they think is the Gnosia, and that person gets put into deep freeze. After they're in the freezer, the AI scans the ship. AGAIN, why not just cycle each member into deep freeze? Probably because it's not something that's easily undone, but the show doesn't explicitly state that, so the question still stands.

One last thing... and this is what made me drop this anime. I'm big on contrivances. I do not like it when a show forces something on me that I know is illogical/wrong and tries to pretend it's not. I hate that. I'm not saying I don't let it slide every now and then, but this show tried to ham-fist the weakest explanation of time travel into the plot that I have ever seen.

Some character named Rocio, or whatever, says this about time loops and time lines, "There's no way to know if there's a cat in the box until after you've opened it; it's a law of cause and effect that was proven thousands of years ago."

— HUH???

Schrödinger's cat is a critique of the nature of reality, not an explanation of time travel or the reason why a fucking grey alien appears at the end of episode 2, FFS!

EXAMPLE: You don't know what's in your birthday present box, right? But, you have an idea that it might be a cat.That is NOT the same as the cause (someone putting the cat in the box) and effect (you opening the box). This show tries to say that instead of someone giving you a cat as a birthday present and you not knowing whether it's alive or dead, there's a goddamn watermelon with grey sweatpants on inside the box BECAUSE time travel--- 🥷🏾 WHAT?. I cannot roll my eyes any harder.

I guess this is fitting for this show, because you think you're getting an anime with the premise of Among Us, but instead you've gotten a big fat pile of dog shit. Happy birthday!
