Kiriyama Renn is an enigmatic and super cool assassin named Mirage, in this almost Bond like thriller, with a unit called K13 in Japan who has the license to kill and clean up messy organizations and people. The police system seems corrupt and vile enough as always, and the villains are mysterious. The main antagonist listens to this recurring opera and each time you hear it, you know the villains are gaining an upper hand. Watch this for the cool music, a very well choreographed set of fight scenes in each episode, and Kiriyama who has little speaking parts but lots of fast action, and a cool car. In fact, the action scenes are short and swift but that is what one looks forward to each episode. They are almost movie quality choreography and design, with each fight scene showing off Mirage's empty hand, or weaponed, or shooting prowess. Mirage is a mysterious killer who dispenses with his missions efficiently, stylishly, and without fail. Even though Kiriyama is not a martial artist, the fight scenes are quite convincing and intricate. And if you can ever figure out who really are the good and bad guys in the Japanese government/police force, good luck...
