Nanakusa Nazuna is a vampire who made a deal with Kou Yamori to drink his blood. She is quite short, standing just a head taller than a middle school boy. Nazuna has a laid-back personality; she's not overly friendly, but she maintains a relaxed presence in most situations.
Nazuna loves playing video games, drinking beer, and making dirty jokes. She is very open about sexual topics, has no problem discussing them, and enjoys teasing others with her humor. However, she is very averse to romance and reacts with strong embarrassment when the word "love" is used in a romantic context.
Nazuna is originally blonde, but in the anime, her hair was changed to a pale purple color. Her eye color varies somewhat in Kotoyama's illustrations. Sometimes she is depicted with her typical blue eyes, other times with brownish-grey, and on rare occasions with yellow eyes.
She works as the owner of a snooze shop, where she helps customers fall asleep in order to drink their blood. However, after trying out a job at the Maid Cafe "Vamp", she decided to work there as a maid as well because she liked the salary and the after-work beer.
