Pretty much what FTGM said, though I'd like to add on it.

I also like how the characters (including the mains) are not perfect. They all have their little or not so little flaws, which makes them more believeable and easier to relate to.

And the antagonists have a clear motivation for the things they do. They don't go around killing people just for the hell of it.

On the con side, even the manga occasionally has misplaced comedy that does more to disrupt than enhance the immersion into the story.
