Gnosia

Yuuri comes to on a drifting space cruiser with no memories, and that's already a bad day. Then it gets worse — one of the four other crew members is secretly a Gnosia, a human infected by a virus that compels them to wipe out everyone else. The catch is they look and act completely normal. The only option the crew has is to debate and vote on who they think the enemy is, then put that person into cold sleep. Get it wrong, and someone else disappears after the next warp jump. This is a TV series from domerica, 21 episodes, adapted from a game that played like a single-player Among Us with a time loop twist. Yuuri keeps reliving these deadly social deduction rounds, and each loop peels back more about the crew — Setsu, Racio, SQ, Jina — and the mystery of what actually happened to the planet Liu-An. The vibe is dark and paranoid, heavy on psychological tension rather than action. Think The Thing meets a Werewolf Game, except the setting is a claustrophobic spaceship and nobody can leave. What makes it stick is how the time loop isn't just a gimmick — it changes what Yuuri knows about each person, which shifts alliances and suspicions in ways that feel genuinely unsettling. If you liked the mind games in something like Danganronpa or the slow-burn dread of sci-fi survival stories, this one's worth your time.
