MIU 404 (2020)

The Mobile Investigative Unit (known as "MIU") of the Tokyo Metropolitan Police Department attempts to solve cases within 24 hours.

Detective Kazumi Shima (Gen Hoshino) is selected as a new member of MIU. He is intelligent, with excellent observation and communication skills. Yet, he does not trust other people. He is unable to find a partner in MIU and is ordered to partner with Police Officer Ai Ibuki (Gou Ayano), who works at a police substation. Ai Ibuki applied for MIU, but he failed. He is in excellent physical condition, but he lacks knowledge and experience as a detective. Kazumi Shima learns about Ai Ibuki's background and he becomes more nervous. Finally, Kazumi Shima has his first meeting with Ai Ibuki.
