~!Died with [Kiku Hoshimi](https://anilist.co/character/269128/Kiku-Hoshimi) at the sunrise after she turned him into a vampire!~

Wracked by insomnia and wanderlust, Kou Yamori is driven onto the moonlit streets every night in an aimless search for something he can’t seem to name. His nightly ritual is marked by purposeless introspection — until he meets Nazuna, who might just be a vampire! Kou’s new companion could offer him dark gifts and a vampire’s immortality. But there are conditions that must be met before Kou can sink his teeth into vampirism, and he’ll have to discover just how far he’s willing to go to satisfy his desires before he can heed the Call of the Night!

One sleepless night, Ko slips out to walk the streets. Life after dark is a revelation! When flirtatious 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 Ko’s past shows up and competes for his attention, his budding relationship with the undead is put to the test!

Ko overcomes his confusion about becoming a vampire and decides to "like" Nazuna, while Nazuna resolves to make Ko "fall in love" with her. Without understanding what "love" even is, the two of them spend their nights together in a frenzy. Meanwhile, Detective Uguisu Anko is closing in with her plot to kill vampires, not just Nazuna. A vampire's weakness is "anything they were attached to when they were human" and so they all try to get rid of this weakness before it's too late. But, Nazuna has no memory of her human life. What is Nazuna's hidden past? Why did Anko start killing vampires? And what is the "secret" that Nazuna and Anko share? For Ko, Nazuna, Anko, a fun "late night" doesn't end here... a new "night" begins!
