Not sure for those into vampire stuff. But...basically the story revolves around 2 characters that are part of a disciplinary committee and are supposed to protect the secret of the night class. (There's basically 2 classes in Cross Academy. Day and Night Class). Secret of the night class: the students are all vampires.
The main heroine, Yuki Cross, and her childhood friend Zero Kiryu, are the ones responsible for not letting the secret of the night class slip and have the day class students know. However...the pureblood vampire Kaname Kuran...who is the main reason the rest of the night class students are there, has an interest in Yuki.
(Any other stuff you want me to elaborate on...I'll try my best).
It's a pretty interesting read. (Though the next volume, #3, comes out in 2 months).
