About Unnatural

Unnatural follows Mikoto Misumi, a seasoned forensic investigator who leads a small team as they piece together the truth behind perplexing deaths. Each episode pulls viewers into the meticulous world of autopsies, trace evidence, and digital forensics, where a single clue can overturn assumptions about how a person died. The team races against time to reconstruct events from scattered data, interviews, and lab results, all while navigating the pressures of a system that expects clear answers. While the cases test their professional judgment, the characters also carry personal stakes and the toll this line of work takes on their lives. The result is a precise, human drama about seeking accountability. While the pace is brisk, the show never sacrifices character depth, letting viewers see the people behind the cases.

Directed by Kentarō Takemura and Yoshiaki Murao, Unnatural comes from creators Ayuko Tsukahara and Akiko Nogi. Debuting in 2018, the series brings a lean, procedure driven approach to Japanese crime drama, grounded in forensic science and teamwork. The storytelling is tight and clinical, mirroring the rhythm of lab work.

With Satomi Ishihara as Mikoto Misumi and a strong supporting cast, the show earns credibility through performances that feel grounded rather than flashy. Its clinical focus and human stories appeal to fans who like forensics told with calm intensity. Ishihara's performance anchors the series, while Kubota and Ichikawa bring complexity to their supporting roles.

Viewers give Unnatural solid marks, with an 8.417 out of 10 rating from 90 votes, signaling broad appeal. The series centers on the tension between scientific certainty and the questions that data cannot answer, while exploring the emotional strain on investigators and families left behind.
