-Relationship between a human and a vampire

It follows the trouble-filled daily life of a mysterious and strikingly beautiful vampire novelist who assists the police in criminal investigations, and a rookie editor who finds himself at the mercy of a non-human existence.

Zen Misaki is a wildly popular bestselling author whose true identity is, unexpectedly, that of a vampire. Using supernatural abilities unique to his inhuman nature, such as nensha (the power to read a person’s memories from their blood), mind reading, and hypnosis, along with his sharp deductive skills, Misaki stylishly solves difficult cases that have left the police at a dead end.

Having long since abandoned his life as a human, Misaki begins the story having lost his sense of purpose, lacking the passion to write new novels and harboring a cynical, world-weary outlook. However, through his interactions with a young editor and an up-and-coming detective, and by solving case after case, he gradually rediscovers his capacity for love, friendship, and the very emotions that make him human.
