Yuki and Zero go into town to do some shopping for the Headmaster, and they are attacked by a fiendish vampire called a "Level E". Two Night Class students, Takuma Ichijo and Senri Shiki, come just on time and slay it, and invite Yuki and Zero to their dormitory at midnight to find out why they killed one of their own kind...
Yuki now knows that Zero is a vampire and is trying to come to terms with it. They are out shopping when a Level E vampire appears. Two Night Class students show up and kill it, inviting Yuki and Zero to come to the Moon Dorm at midnight for answers. After all vampires just don't kill each other every day.
So they go to the moon dorm at midnight and Yuki gets her answers, Level E vampires are evil and insane. All they care about is blood. Nothing more. She also finds out that Level E vampires used to be human and all turned vampires will turn into a Level E. Just like Zero. He might one day lose his mind and only care for blood. Yuki also finds out that Kaname ordered the students to kill the Level E to keep everyone safe.
Zero gets overpowered by the smell of blood and takes off. Yuki follows him and he almost bites her again but she pulls them into the pool, hoping he comes to his senses. Then Zero's master shows up and puts a gun to his head.
Yuki makes Zero drink his blood. She won't allow him to die or give up till he's reached Level E. He's so upset at himself for needing blood but he drinks from her.
You can see how much Zero and Kanama love Yuki and both want her to be safe. Zero finally decides not to give in and he will keep fighting until the end. The ending is a huge cliffhanger, with Zero's master telling him 'that woman' is still alive. Who is this woman? I'm sure we'll find out in volume 3.
I love this series so much. It's probably my favorite manga series right up there next to Death Note. None will beat these two mangas to me. I'm so excited to read this again so I can finally finish it. The art is just so stunning and perfect, the plot is actually something thought out and not just silliness. It's just the best.
