One of my favorite aspects of manga is the art work, and on that front Vampire Knight totally delivers. 
 The other thing I love about manga is the imaginative, fantastic story lines. I read Vampire Knight after reading Twilight, and I liked it a lot more for one big reason: the protagonist, Yuuki Cross, is much more than the typical shoujo female lead! Not only is she At Yuuki's school, day-class students are humans like her. But night class students are vampires. So by day, she's a "normal" student, but by night, she transforms from into a vigilant protector. Alongside her best friend, Zero, Yuuki watches over the school's students to ensure that night class students don't overstep their boundaries, and that day class students don't find out about their vampire classmates. All in all, it makes for a great story line with a lot of natural tension. On top of that, of course, is the romantic tension between Yuuki and Zero. 
 I think Vampire Knight is a perfect marriage of shoujo romance and dark, moody action. I would recommend this manga to anyone who typically reads YA fantasy, paranormal romance, or shoujo manga in general. It's well thought out and beautifully illustrated, and I really enjoyed Volume 1. Don't stop there, though - there's so much more to this manga!
