MIU 404 (2020)

Kai Honma (Kento Nakajima) and Jiro Ichinose (Sho Hirano) are cadets at the police academy. Kai Honma is smart, diligent and has excellent memory. At the police academy, he works on criminal profiling. Unlike Kai Honma, Jiro Ichinose is in excellent physical condition. He has a warm heart and honest personality.

Kai Honma and Jiro Ichinose get involved in cases while at the police academy. Based on knowledge they gained from their training, they solve cases with help of fellow cadets and detectives. During this time, Kai Honma and Jiro Ichinose become best friends.

Both are very fun detective dramas that focus on two male leads with opposite personalities. In Bitter Blood, it's an estranged father-son dynamic where the two end up having to work together. In MIU404, they also have to learn how to work as partners after initially not wanting to.

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.

The two main characters have a very good chemistry and they have a lot of potential. It's a bromance series where the main leads solve mysteries together with a lot of comedy.

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 are detective dramas. In both dramas, the chemistry between the partners is also amazing. In both dramas there is a case which is continued from the past.

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.

These two dramas for one have Suda Masaki acting in them. He's super good!
Next is these both have two guys investigating cases together, though one is a information business and the other involves the police.
And duh, bromance.

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.
