Season 1

Unnatural (2018), Season 1 is a Japanese forensic procedural you can watch online on iFILM — 10 episodes built around a private lab where examiner Mikoto Misumi and her team dig out the truth the police were happy to file as a natural death.

The season works case by case, and each one opens on an autopsy table rather than a chase. A nameless poison. A suicide that doesn't add up. A witness who shouldn't exist. A killer who leaves his puzzles inside the bodies. Underneath the standalone files a longer thread surfaces, tied to Mikoto's own old wound — the reason she chose to work with the dead in the first place. The lab argues, gets things wrong, and carries other people's grief instead of just signing off reports.

Akiko Nogi's writing keeps the cold precision of the morgue tied to the living people behind every case, and Satomi Ishihara carries it all without melodrama. Stream all episodes of Unnatural Season 1 on iFILM.
