Looking for something

+Minimal amount of "Ecchi fanservice".
+A good plot that isn't shallow.
+Murder. (Yes I like murder in fiction)

Perhaps some magical elements or robots n stuff if that's what it is about. I'm fine with anything as long as it fits the three criterias above.

Also,I loved Code Geass,Future Diary,Death Note,Guilty Crown,Angel Beats (okay that one tapped my emotional side a bit instead but I liked it),Zipang,Pumpkin Scissors,Area 88,etc.

Basically,I am flexible,but I would prefer if there were suggestions that are similar to these.

Thanks in advance.
