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.
Considering that genies are a "magical spirit believed to take human form and serve the person who calls it", I would say that a title which has a character who fits this description would qualify. Some people have said that Aa! Megami-sama! OVA and Shinpi no Sekai El Hazard are genie titles.
