Gnosia

In the anime Gnosia, a spaceship adrift in the void becomes the stage for a deadly game of deception. A mysterious alien threat known as the Gnosia has infiltrated the crew, perfectly mimicking human form. To survive, the humans must vote each day to identify and place the most suspicious individual into cold sleep.

The protagonist, Yuriko (Yuri), finds herself trapped in a confounding time loop, forced to relive the same cycle of suspicion and votes no matter the outcome. Each reset offers a chance to uncover the truth—not just about the hidden enemy, but about the secrets every crew member carries and the greater mystery behind the loop itself.

This anime masterfully blends sci-fi suspense with psychological intrigue, creating a gripping narrative where trust is a luxury and every loop peels back another layer of the haunting truth.
