Vampire Knight has a very unique and good story. it really had me want to see the next episode every time. this was also very much because I was sucked into the anime due a good amount of tension. it sometimes felt like I was one of the main characters. the story is quite serious and emotional, but not at all boring and with some nice humurous parts in it (but they're not out of place). So if you want something else for a try, and you love action, humor and a good story (and are not afraid to see blood), you should really try Vampire Knight
