This drama is set in the same universe as Unnatural (directed and written by the same team). So if you like Unnatural, I’m sure you’ll love MIU404 instantly! Somehow the atmosphere and style of these two are very similar. Each episode of MIU told different cases and story but it also carried a big case(s) that linked all episodes or at least from episode 3 onwards.

Both are Japanese Crime Drama Thrillers solving ONE CASE per EPISODE.
Both have team work / Police Officers duo working on the cases.
For both dramas, in the duo :
One uses intelligence n the other uses physical strength.
One is serious n the other is silly, haha.
Crime drama ardent lovers will definitely enjoy both and crave for more seasons and more cases for both the dramas.
I miss both the duos from both the dramas
(My rating for both is 9.5 ?)

The biggest similarity between the two shows is the dynamic between the two leads, who are police officers tasked to work together and solve cases. One of the officers is very serious and has a mysterious history whereas the other is more outgoing and 'fun'.
In both shows, the two leads are reluctant to work together but over time, become very close and work well together.
The biggest difference in the shows is that MIU404 is more comedic and wholesome than OS, which is grittier and deals with more serious crimes.
Both are good watches if you are looking for a crime-solving duo that has good chemistry.

Both drama are detective-based. But in 99.9 Keiji, the protagonist is a lawyer(yet, most of the job he does is detective-work). Like Ibuki in MIU 404, Miyama in 99.9 Keiji is a funny guy. Moreover Miyama's partner is even dumber and funnier in contrast to Ibuki's partner who is not always funny. If you like the humour part of MIU 404 then 99.9 Keiji must be your next stop, as it delivers humour at an even higher level.




Both are comedies with a male duo and a great cast list and plots. With MIU404, it's slightly more serious, yet it's still a comedy (at least the beginning is) and like Dangerless Detectives, the 'real' story doesn't start until around halfway through. MIU404 has more and longer episodes so there is more depth to the characters and their backgrounds, as well as having more time to explore various stories. Though a bit different, both shows are great with good acting and screenwriting.
