Self-explanatory. Series who's primary focus is fighting would fit into this segment. Yu Yu Hakusho and Ranma 1/2 are classified as fighting series. But if you can, then please select a more specific keyword instead, such as "Gun-Action" or "Swordplay"; maybe some day we'll completely split up this category into some more terms of this sort.
Titles that contain characters who suffer from depression would fall into this category if this is of significant importance for the storyline.
