Unable to sleep or find genuine satisfaction in his daily life, Ko Yamori withdraws from school and begins wandering the streets at night. During one of his nocturnal outings, he encounters Nazuna Nanakusa, a vampire who introduces him to the appeal of life after dark. Ko becomes interested in becoming a vampire himself; however, to do so, he must first fall in love with her, as required by the transformation rules.

Ko Yamori (夜守 コウ, Yamori Kō) Voiced by: Gen Satō, Sayaka SenbongiEp. 2 credits (young) (Japanese); Gabriel Regojo, Katelyn Barr (young) (English) Ko is a 14-year-old junior high student whose growing dissatisfaction with life drives him to wander the streets at night. He hopes to escape his humanity by becoming a vampire through loving Nazuna. Gradually, he gains the ability to enter a half-vampire state, first triggered by emotional turmoil or physical blood loss, including minor wounds. Anko supplies him with an ear-piercing kit to control these transformations, theorizing that frequent use or stronger romantic attachment could complete his transition into a full vampire. Nazuna Nanakusa (七草 ナズナ, Nanakusa Nazuna) Voiced by: Sora Amamiya (Japanese); Natalie Rial (English) Nazuna is a unique born vampire, the hybrid offspring of a vampire mother and a human father, who meets Ko during his nightly walks. She appears as a young girl but is estimated to be 30 to 40 years old. Her unusual heritage causes her to mature rapidly while retaining childlike traits, making her an outcast among other vampires. A playful but socially awkward figure, she often teases Ko and enjoys crude humor and beer. Having learned about the world primarily from television, games, and manga, her behavior often subverts traditional vampire stereotypes. Her sole weakness is her own preserved umbilical cord.

Akira Asai (朝井 アキラ, Asai Akira) Voiced by: Yumiri Hanamori (Japanese); Jade Kelly, Juliet Simmons (young) (English) Ko's childhood friend, who lives in the same apartment complex as him. She attempts to try and convince him to return to school, but also, reluctantly, is supportive of his dream of becoming a vampire. She treasures her relationship with Ko and Mahiru. Kiyosumi Shirakawa (白河 清澄, Shirakawa Kiyosumi) Voiced by: Yoko Hikasa (Japanese); Kelly Greenshield (English) A busy-body office worker and one of Nazuna's clients from her massage gig. After hearing about her struggles in life due to her heavy work schedule, Ko vows to help her, as he feels they share the same plight, and will offer to turn her into a vampire when he becomes one himself. Mahiru Seki (夕 真昼, Seki Mahiru) Voiced by: Kensho Ono, Sara MatsumotoEp. 8 credits (young) (Japanese); Daman Mills (English) A popular boy at school, and one of Ko and Akira's old friends, who also starts to hang out at night. He is initially apprehensive of Ko's dream of becoming a vampire after they are attacked by one, but after learning the woman he fell in love with, Kiku Hoshimi, is also one, he decides to let himself be turned too. Akihito Akiyama (秋山 昭人, Akiyama Akihito) Voiced by: Hiroyuki Yoshino (Japanese); James Marler (English) Seri's vampire underling. He befriended Seri, and after a situation where he was saved by Ko who helped the two of them understand their feelings, he asked her to turn him into a vampire. He is often referred to as "Draggo", "Menhera-san'", or "Mr. Mental" by Ko. Anko Uguisu (鶯 餡子, Uguisu Anko) Voiced by: Miyuki Sawashiro (Japanese); Jessica Calvello (English) A chain-smoking vampire hunter who initially opposes Ko and the vampires, specializing in killing them by exploiting their personal mementos. She is later revealed to be Nazuna's first friend and attempted familiar. Her hatred stems from her vampire father murdering her mother, an act for which she subsequently destroyed him using his weakness. After a suicide attempt meant to expose vampirism, she reconciles with Nazuna. With Ko's help, she confronts Kiku Hoshimi, the vampire who turned her father, and finds resolution. Although initially incapable of love due to severe mental trauma, she eventually recovers and displays attraction to both men and women.

Her character was cut from the anime, only showing up in the background. Kei Yamori (夜守 ケイ, Yamori Kei) Kei is Ko's mother. She gave birth and got married at the age of twenty and got a divorce when her husband cheated on her. From that point on, she has been raising Ko as a single mother and works in the night entertainment industry.

Seri Kikyo (桔梗 セリ, Kikyō Seri) Voiced by: Haruka Tomatsu (Japanese); Christina Kelly (English) A flirtatious vampire who resembles a gyaru. She approaches Ko when she hears that Nazuna is spending the night with a human where she attempts to suck his blood, until she is stopped by Nazuna. The two do not get along well, as she questions why Nazuna is spending so much time with Ko while not having turned him yet. Niko Hirata (平田 ニコ, Hirata Niko) Voiced by: Eri Kitamura (Japanese); Monica Rial (English) A vampire who doubles as a teacher who teaches night classes. She is not as accepting of Ko in her first encounter with him, but becomes willing to let him stay with Nazuna so long as he fulfills his intentions on becoming a vampire and Nazuna continues to suck his blood. Kabura Honda (本田 カブラ, Honda Kabura) Voiced by: Shizuka Itō (Japanese); Patricia Duran (English) A vampire who wears elegant dresses, she works as a nurse and is Nazuna's adoptive mother. Hopelessly in love with Nazuna's mother, Haru Nanakusa, the woman who turned her, she projects these feelings onto Nazuna due to their similar appearance. This results in her acting as an overbearing and doting parental figure. Although becoming a vampire allowed her to feel attraction to men, she still prefers women, holding onto the memory of her first love for Haru. Midori Kohakobe (小繁縷 ミドリ, Kohakobe Midori) Voiced by: Naomi Ōzora (Japanese); Emily Neves (English) A long-sleeved shirt-wearing vampire works in a maid cafe and is highly aware of her own good looks, which can make her seem self-absorbed.

Hatsuka Suzushiro (蘿蔔 ハツカ, Suzushiro Hatsuka) Voiced by: Azumi Waki (Japanese); Annie Wild (English) A male vampire possesses a notably feminine appearance due to his slender body, shoulder-length hair, cute face, and choice of clothing.

Kiku Hoshimi (星見 キク, Hoshimi Kiku) Voiced by: Rina Satō (Japanese); Nickolette Kong (English) Kiku is an enigmatic, sociopathic vampire who has turned countless humans into servants. Obsessed with testing unproven vampiric theories, she seeks to validate a rule suggesting a vampire who loves a human will kill them through biting. Her current target is Mahiru. Eventually, her true motive emerges: she aims to become human by drinking the blood of someone she loves, believing this will reverse her vampirism. Haru Nanakusa (七草 ハル, Nanakusa Haru) Voiced by: Maaya Uchida (Japanese); Kira Vincent-Davis (English) Haru was a vampire night-nurse and a friend of Kiku Hoshimi who investigated a method to revert back to being human, which eventually led to the birth of her daughter Nazuna. LoveGreen Voiced by: Tomokazu Sugita (Japanese); Joe Daniels (English) LoveGreen—or LG (エルジー, Eru Jī) for short—is Midori's offspring and an otaku superfan of hers, referring to themselves in the third person.
