A drama in typical J-fashion that was written and directed in a focused manner, yet never fail to deliver a connection with the task force (main cast) and even the guest stars (each crime in a new episode).

The positives:
Plot
Each episode but one delivers a new cold case that needs solving. Unwavering each episode starts moments before a crime took place. The writing dives straight into the task force gathering clues, gathering info, meeting potential suspects. Unlike C or even K dramas that take time (or too much time) developing individual characters of main cast, this drama lets you observe their characters as they so the job. And through each case, we saw how it may connect to the main cast member. How it effected them and drop hints of the ghosts in their closet. Simple interactions as they meet at work or after work allows you to peek into their lives. Its something to pick up on your own, yet its purposeful and never as afterthought.

Character
Captain Ishikawa is like that woman you admire. Who is proficient, efficient and sometimes blunt. Who seems to be steadfast yet rigid in her stance. Who looks calm on the surface but like a deep pool of water, you are attracted to find more about her and indeed theres much in her past that made her the way she is now.

Takagi, the new guy who quickly found his groove with the rest of the team. He seem to see thing on the surface but you come to find out his many strengths, not just as a member of the taskforce but as a person. I find his nature sometimes sweet, sometkmes gullible. But he forms a fascinating contrast to Ishikawa

Motoki, the vice and moat senior from appearance to demeanor was always in control, dependable and conducts his team in a soft leader manner. We also saw a bit of how his work ate away on his personal life and family.

Tachikawa and Kaneko rounds up the team and both are very likable. Tachikawa exudes a sometime male egoism and biasness but hes a good cop that gains your favor as the drama progresses. I look forward to knowing more of them as character and their own background story in Season2.

Acting
The actors playing the main casts were all spot on and effective in their roles. Yoshida You is new to me and she amazes me with her own screen charisma. Shes the type of actress that draws you in from both performance and appearance. Not just attractive appeal but her portrayal of Ishikawa was multi facet, sometimes strong and tough, sometimes calm and sharp, sometimes bias and emotional and when she cracked, vulnerable and even broken. Exceptional is the only word i can sum up for both the actress and her character.

Music
Opening theme and songs used were very nice. A lot of nostalgic english songs used too.

Crime and story range
Almost every theme, with different victims in different background, decade, was explored. Suspects, motives and culprits were variable too. Cases involving kids were particularly emotional for me. Most of the cases gets you emotiobally invested and a few makes you put not just your detectice hat on but criminalpsychology too.

The negatives
I wish the season is longer. 10 episodes wasnt enough for me. The other was tje development in Cap Ishikawa's sister while i dont hate it, i didnt particularly like it either.

Verdict
If you enjoy the genre of crime, investigation,detective and mystery, this drama tick all the boxes. Theres not much frills and diversion, a major plus in my book. Im amazed that even though each episode isnt long and total episode count isnt alot, it manages to develop the main cast with the limited screentime on their personal lives. Season 2 will be out in less than a week at the time of writing this review. My suggestion is binge watch this drama's season 1, you wont be disappointed.
