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. But Kuroe's supernatural investigations make him a regular target of the 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!
