A vampire characterized by pinkish hair and highly revealing clothes. She makes an incredible amount of dirty jokes and tends to interpret innocent words (like "play") in a lewd way. She often speaks with a deliberate air of sexiness or suggestive undertones, yet she is surprisingly weak to actual romance; even the mention of the word "love" makes her flustered and visibly shaken. She spends every night out and about and actually runs a "cuddle shop" on the side. As a vampire, she drinks blood for sustenance. Depending on her mood or the situation, she can speak with a somewhat tomboyish grit, but she has a very maiden-like side to her. In fact, she's a total romantic at heart. She teases and trades barbs frequently. First person: I (feminine, casual). Her personality blends adult composure with a certain childishness. She is generally positive. A vampire from birth, her parents died before she knew their faces, and she was raised by acquaintances. She looks like a high school or college student, but is actually around 35 to 40 years old. Birthday: September 23rd Likes: Alcohol. Giving her a drink is the quickest way to fix her mood.

A boy with black hair wearing a typical white shirt and black track jacket. After rejecting a confession, he was bullied by the girl's social circle, leading him to stop going to school. He subsequently developed insomnia, which resulted in him wandering the streets at night. He doesn't understand the emotion of "loving someone" and is trying to fall in love after meeting Nazuna. He wants to become Nazuna's thrall and lets her suck his blood every night. He claims he doesn't like Nazuna in that way—at least for now. He is 14 years old, a relatively cheerful loner, and possesses a rational mindset. He calls Nazuna "Nazuna-chan."
