Tokyo has suffered a truly intense terrorist attack that has left its marks on all aspects of society. When a nuclear weapon is stolen from a secret military base, and soon after, an attack is launched by two strange individuals who have taken responsibility by posting a video on-line, the whole government mechanism has a fit. Soon, a task force is assembled, headed by Kurahashi, with a mission of solving the enigmas the two perpetrators leave, but it is Kenjiro Shibazaki, an ex-detective who has been demoted to the records division, that has the most success in solving them. As we learn more about the two "terrorists," Nine and Twelve, another agenda comes to the fore, while Lisa Mishima, a student, gets tangled with them by chance, and Five, an agent of the FBI takes over the investigation.

I loved this show. It had just the right amount of suspense and character development to make something that just strikes the heart. The story for me was bit slow but ending made it worth watching.. the characters are interesting nicely depicted..
