Sakuya used to be a fearsome high rank vampire until he fell inlove with Atsumi. Now, he's fallen so low that he can't even drink other people's blood because only Atsumi's blood suits his taste. The problem is, Atsumi is not only a guy, but also a vampire hunter... Their love is more than just complicated, it's a game of life and death for them both!
