This one catches you off guard, a show about a kid wandering streets at 3 AM because he can't stand being still, finding someone who actually gets the numbness, and suddenly that purposeless drifting starts feeling like the only honest thing left. Nazuna isn't a prize to win or a salvation fantasy; she's just there in the dark with him, which somehow matters more than any grand vampire mythology ever could. The animation bathes every empty street and quiet conversation in this specific loneliness that makes you recognize yourself in Kou's insomnia, even if you'd never admit it out loud.

Kou Yamori is a middle schooler who cannot make sense of love and has quit going to school. Kept awake by insomnia and a longing he can't put into words, he begins wandering the empty streets after dark. One night he meets a strange, flirtatious girl named Nazuna Nanakusa, who takes him back to her place in an abandoned building and then bites his neck, revealing that she is a vampire. Becoming one himself is not so simple: Kou can only turn if the vampire who bites him is someone he truly loves. Eager to leave his dull human life behind, he sets out to fall in love with Nazuna. Their late-night outings blend comedy, romance and psychological unease, and when a girl from Kou's past appears and vies for his attention, his bond with Nazuna is put to the test.
