Hello, I'm searching for some thriller anime.

I saw Monster which is the best thriller anime in my opinion (and probably my best anime i ever watched in my life).
I saw a lot of thriller animes but none of them are very good. I'm searching for an adult thriller with a mature design and good plot of course (for exemple, i don't want animes like Higurashi no naku koro ni with that ridiculous loli design; i already saw it and it wasn't very good except first episodes). I like Gankutsuou too. I don't want animes like Noir, Witch Hunter Robin, Darker than black... I like detective anime too like Detective Conan but it became boring and chara design isn't good. I watched Gungrave and it was very good. AND I DON'T WANT COMIC/FAN SERVICE/ECCHI/LOLI thriller anime -_-. I hate that!

I watched Death Note but it's a shonen and not as powerful as Monster. It's not bad but I want more! I already read 20th Century Boys and Pluto of Urasawa (Monster autor) and it was incredible. But i'm searching for a thriller anime.

Well if you have some suggestions, please tell me ^^. I hope there is some anime like Monster...
