hello, I'm looking for a more serious police/detective manga, something similar to the real world.

Preferably if it follows the person as he gains reputation and where his career actually moves forwards, and doesn't just stay the same throughout the whole manga

when I mean serious its more that it is realistic, no supernatural or the such please

Thanks! 😀

I liked Until Death do us part.

Lego & manga. The building blocks of life.

I liked Until Death do us part.

The detective is only a side character and it's not what I'd call realistic.

Jiraishin

Maybe Remote.

Shibatora is about a police who deals with crimes involving minors. Although it has a little bit of supernatural in it (really, just a little), it's an awesome police/detective manga as a whole.
Ottori Sousa also works as a police/detective manga, not so sure about the moving-up-the-ranks bit, though.

Maybe Domu, but its a oneshot so there's no 'moving up the ranks' involved. There's two characters with psychic abilities, but its done in a realistic manner so it shouldn't bother you.

Thank you all for your replies, really helpful 😀

I'm about to give Shibatora, Ottori Sousa, Remote and Jiraishin a try right after I'm done with this reply

I forgot to specify, no one-shots, they are what i call an emotional suicide, if its good, i just want more of it, but can't get it 😢 but thanks anyways highway-star!

maybe you could also try manhole. even though it follows only one (main and only) case, it is solid police work.
perhaps also Seizon - Life. father decides to solve the dissapearance of his daughter. what you have in the story is also fairly realistic detective footwork.
