This drama was awesome! Short - only 5 episodes 45 or so minutes each - but so good! It told the story of a special unauthorized police unit nicknamed Diver and the cases they solved.

For me, the main draw was Fukushi Sota as Kurosawa. His Kurosawa was a ruthless genius who had no care for his life or his safety, who focused solely on "eradicating evil" at any cost, including dead bodies if need be. Because once, in the past, he made a mistake and it cost someone dear to him his life. And since then, he had no tolerance for mistakes or bad guys - or corrupt cops.

One thing I didn't like much was the very abrupt ending, that there was no "bridge" between the pier scene and the last scene. It felt like there was so much that the drama skipped. I really wanted to see Kurosawa and Sho bond, Kurosawa telling him the truth about what happened back in the past... And also - how was Kurosawa saved, considering he got shot twice?! Argh!

Overall, a great drama with no fillers. Loved it!
