There are worse things than being a vampire. For recently turned vampiress Minato Misaki, there is nothing more painful than watching her human companion, the former vampire hunter turned investigative author, Kurose Kuroe, risk his life to protect her.

For Misaki, vampirism and the beastly powers that come with it are something that she wouldn't wish on her worst enemy, let alone her beloved Kuroe. But Kuroe's supernatural investigations make him a regular target of vampires and all sorts of undead creatures of the night. The only way to save him from these deadly threats may be to do the one thing that Misaki fears the most: to turn Kuroe into a vampire for his own protection.
