If you loved La ritournelle du démon, try The Inugamis

Ce qu'ils partagent
Both films are directed by Kon Ichikawa, and they both carry the dread, paranoid, slow burn mood tags, and they sit in Horror / Mystery territory. If that's the register that drew you to La ritournelle du démon, the second film will land in a comparable space — through a different lens.

What The Inugamis is
A mountain villa, winter. A single chrysanthemum wilts on a shrine shelf. Tamayo arrives, summoned by the dying patriarch. His four grandsons circle, their good manners brittle as old lacquer. A festival drum begins muffled beneath the floorboards.
