Blood Alone

In BLOOD ALONE you will be drowned by the little vampire Misaki innocent but strong feelings regarding the human Kuroe, the man she likes. In this manga there are some action, romance and lots of mystery...From Wikipedia: Kuroe Kurose is a former vampire hunter, turned private detective and best-selling author. He lives in a modern-day city with Misaki Minato, an adolescent girl who has recently been turned into a vampire. Kuroe's investigations often lead him to battle vampires and other undead creatures, sometimes with the support of Higure, a leading figure in the vampire world. Misaki meanwhile struggles to get to terms with her vampire nature and her love for Kuroe.From Infinity Studios:Enter Misaki, perhaps the most innocent and most sincere young lady there ever was. It’s almost inconceivable that she could be a vampire. And with her powers as a vampire, she could easily entice any human to do her bidding…but she chooses not to. Especially when it comes to Kuroe, a young author who has a deep running past with vampires. This wonderful story of pure innocent love charmingly bonds Misaki to the readers. She’ll absolutely delight you with her earnest love for a human and her resolve to protect a willing mutual relationship versus turning Kuroe.
