Rin wakes up broken every few episodes, and the show makes you sit with that. Not as spectacle, but as the cost of knowing too much about a world that doesn't want to be understood. The mythology is real enough to hurt, but the plot collapses under its own weight by the middle, leaving you with gorgeous cosmic horror that forgot how to breathe. Watch it for the first three episodes if you want to experience something genuinely unsettling; stay for the rest only if you accept that sometimes the mystery matters more than the answer.
Rin Asogi works as a private detective in a world where the supernatural bleeds into the mundane. She's also immortal, which means death is less of an occupational hazard and more of a recurring inconvenience. Across six episodes spanning decades, Rin finds herself caught in an escalating nightmare orchestrated by Apos, an ageless entity determined to use her as a sacrifice to Yggdrasil, the cosmic tree binding existence itself. What makes Rin's predicament hell isn't just the repeated violence she endures. Apos feeds on her accumulated memories, stripping away pieces of her identity with each cycle of death and rebirth. As Rin pieces together fragments of her past, she realizes the threat extends far beyond personal survival. Apos's obsession with sacrificing her could unravel reality entirely. This is horror dressed in pulp detective noir, where graphic body horror and existential dread share equal weight. The short episode count compounds the intensity, making each installment feel like a compressed nightmare. Viewers drawn to dark supernatural thrillers that don't shy away from visceral imagery will find something relentlessly unsettling here.
