Keizoku is a Japanese mystery thriller created first as a TV drama and later as a film. It is about Detective Jun Shibata, who handles unsolved cases with her hardened partner Tōru Mayama.

The television series was broadcast in eleven episodes between 8 January and 19 March 1999. A two-hour "special drama" was then broadcast on 24 December 1999. The series has been called "epoch-making" in the police procedural genre on Japanese television.

Jun Hashimoto is a sci-fi novel writer, but he isn't popular at all. He lives off of his savings. One day, his editor Tateyama assigns him a job: he is to write a "love" themed short story for a web magazine oriented towards youths. At first Jun refuses, because he has never written a love story before, but Tateyama pushes him to write one. The deadline is imminent. Jun's childhood friend Keisuke Murata then appears in front of him. Jun complains to Keisuke that he can't write, but while talking to him, he comes up with an idea.

Like the original series, "SPEC" will revolve around a pair of police detectives as part of a special division solving difficult cases (Mishou). Touma Saya is a woman with an IQ of 201 and an inability to "read the atmosphere" in social situations. Due to a previous case, her left arm is in a sling. Her partner Sebumi Takeru used to be the star performer of the Metropolitan Police. After some incident however, he was transferred to Mishou. Those two track down offenders with special abilities(SPEC) who managed to get away with their crimes.

When easy-going Aoyagi meets an old friend for a fishing trip, he ends up drugged, framed for the Prime Minister's assassination, and on the run from corrupt cops. It's only the beginning of what quickly becomes the worst, weirdest day of his life. But he'll get by with a little help from his friends, who include a famous pop diva, a rockabilly deliveryman, a crippled old gangster, and the world's most cheerful serial killer.

Again we follow a pair of police detectives as they track down offenders with special abilities (SPEC). However, since the events of the previous chapters, MPD Public Security's special division for solving cases involving unknown circumstances (Mishou) no longer exists. Instead, there is now an exclusive special division (Tokumu) as part of the Cabinet Information Research Office that only deals with cases involving SPEC holders led by Nonomura Koutarou's younger brother, Nonomura Koujirou
