Anything from Inio Asano. But Oyasumi Punpun would be a good place to start.
Aside from that, I think these are also perfect :

If you would like something school-like with mystery and deep meaning, see Hyouka.
I need recommendations on good series that are deep, & thought provoking (manga or anime). I love Dororo, & ever since I finished watching the series, it left a hole in my heart I need to fill. Genre doesn't matter, I just want something that is profoundly deep, & make me question stuff about life/morality/right & wrong, etc. Anyone got good recommendations?
