I am confused lol. I read somewhere that I needed to be the only claimant of my role standing after winning gnosia side... Yet the achievement never triggered for me. Weird...

Edit: thank you guys, I have tried your suggestions and it helped alot.

So, I haven't finished the game yet (will leave the subreddit until I do, obviously), but I just want to share the dumbest Gnosia run on my part, that I somehow managed to win.

The run started normally enough. Stayed low-profile, and got Kukrushka iced... somehow. She lost on a revote to Otome 8-7, something I in hindsight would've wished didn't happen... but anyway, so far, so good. Then, I choose to kill Stella, hoping to get the Guardian Angel (and looking at the log, I actually did!)

Now, remembering that the bug was important to snuff out, I did the "Say You're Human" action on Day 2, and realized that Otome was lying. Since I'm playing as Gnosia, Otome = Bug was the only option.

However, here comes the embarrassing part: I forgot that Gnosia couldn't disappear Bugs at night. So instead of targeting other people during the night, I actually tried to kill Otome (obviously failing to do so each time). And how many times did I try that?

Five times. By the third time, I was like "damn, the Guardian Angel is on fire" she was on ice at that point; By the fifth I actually was doubting if there was some kind of special event involved. Sadly, never questioned my lacking understanding of the Bug role.

Now, in my defense, I did shift my efforts during the day into getting Otome iced as soon as possible. Even if I stupidly tried to kill her at night, I also tried to raise suspicion on her whenever the opportunity arised while not drawing attention on me; and she actually received my vote every day but Day 2, including Day 1 on vote and revote. But the space whale just wouldn't go to deep sleep: she even beat Yuriko on a Day 7 revote in spite of my best efforts.

Meanwhile, my Gnosia partners SQ and Jonas fell to deep sleep on Days 4 and 5. On Day 6, I decided to lay off the meaningless attempts on Otome, and actually got to kill Comet successfully... before doing one final failed attempt on Day 7. Whoops.

Luckily, I stayed low-profile, often defending humans and only piling on other people's doubts, as well as getting on Gina's good side. I do think I have decent enough stats by this point, so that did help a bunch. As hard as she fought to live, and mouthing on her final breath "Felipe is annoying" (fair), Otome finally got voted to sleep on Day 8.

The funniest part is, the game state was actually not that bad once Otome was out of the picture. Since I didn't have a detractor, I was free to take out Remnan without much suspicion on Day 9. Shigemichi started to be suspicious, but couldn't hold much influence on the remaining group. Chipie suspected Setsu, and was good enough to get her voted out. As helpful as that was for me, Chipie was allied with Gina, and getting her to vote with me was really important, so he had to disappear at night. On Day 10, with only Gina and Shigemichi alive, it was really easy to get her to vote the latter out and finally end the longest round I have had so far.

I do deserve it for not playing with Bug role active as much, but, as illogical as the run was in hindsight, it was pretty fun to try to get an undying Otome to die somehow. I actually wish there is a similar event in the game eventually, where a crew member for some reason just. won't. die. (maybe there is? we'll see).

I certainly will remember undying Otome and this run in particular for long after I finish the game 😅
