Kitami Makoto

Tenshu is imprisoned and sentenced to death for murdering the men who raped his girlfriend. However, he manages to survive his execution and is presented with an option: face another execution attempt or subject himself to their bizarre and dangerous experiments.

The show is based on the "Jiu" suspense novel series by Honda Tetsuya. Motoko (Kuroki) is a fierce, physically capable investigator with a strong battle instinct, while Misaki (Tabe) is more intellectual, kind-hearted, and naive. The two of them are both working to track down Jiu, the ringleader responsible for a series of brutal crimes.
