This reminded me a lot of Cowboy Bebop (An anime SciFi from about 20 years ago centered around a team of shady bounty hunters living in an era where humanity had colonized the solar system) in terms of the general atmosphere, body count, and characters.
The use of confusing flashbacks which are later explained is very similar. Also, Detective Miller losing his job and hanging up his hat before striking out on his own instantly brought back memories of Jet Black, who wore a hat as an ISSP cop, but typically not as a bounty hunter.
Overall an entertaining series.
