Antisocial, dorky boy seeks fun-loving, sexy vampire for blood-sucking and transforming into her minion.

Nanakusa is a vampire. That’s okay with human Ko. He wants to be one too. But transformation doesn’t come that easily...

When Nazuna invites Ko to spend the night at her place in an abandoned building, he's stoked! But then he awakens to kisses on his neck with a little too much bite to them... Is it just the delicious taste of his blood that makes her meet him night after night for late-night adventures, conversation and...naps? Or something else? Then, when a cute girl from Yamori’s past shows up and competes for his attention, his budding relationship with the undead is put to the test!

What’s the difference between desire and love? Does Nazuna know any better than Ko? What about Ko’s childhood friend Akira? Unable to answer these romantic questions, Ko and Nazuna go swimming. Turns out bathing beauties at pools are just as hot at night as in the blazing sunshine at the beach... Then, Ko gets jealous when he learns about Nazuna’s night job. But after she drafts him into temping for her, the two of them join forces to save a client from her boss—and herself.

But only to a certain special someone. Unfortunately, there’s a time limit on being "turned," which raises the...uh...stakes. Then, Ko follows some dating advice that backfires. Undeterred, he tries to help another vampire and mortal mend their love/hate relationship.
