Nazuna Nanakusa's character and role in Call of the Night isn't just important, she's the entire gravitational center of the series. Without her lazy, beer-drinking, game-playing presence, this anime would be another forgettable slice-of-life with a moody teenager wandering around at 3 AM. She's a born vampire who breaks every rule in the book, and she's the reason the show works at all.
Most vampire stories give you brooding immortals in castles or high schoolers with glitter skin. Nazuna subverts all of that by being a complete slob who happens to have superhuman strength. She lives in a barely furnished apartment, plays video games until dawn, drinks cheap beer from convenience stores, and makes dirty jokes that would make a sailor blush. Yet she's also got this weird fear of genuine romantic connection that creates the central tension of the entire plot. She's messy, contradictory, and way more interesting than the protagonist she's supposed to be supporting.
She's a Born Vampire Not a Bitten One
Here's the thing most casual viewers miss about Nazuna Nanakusa's character and role in Call of the Night. She isn't some human who got bit and turned into a creature of the night. She was born this way. Her mother Haru was a full vampire and her dad was human, making Nazuna a rare hybrid who inherited powers without the trauma of transformation. This matters because it explains why she's so casual about being a vampire. She didn't lose her humanity, she never had it to begin with, at least not in the traditional sense.
Because she's a born vampire, she has inherent mastery over abilities that turned vampires have to learn. She can phase through walls, regenerate from gunshot wounds, leap across buildings like she's flying, and rip concrete apart with her bare hands. Apparently she's rated at building-level destruction in terms of raw power, which puts her above most of the cast. But here's the kicker, she doesn't take any of this seriously. She's lazy about her powers, barely trains, and still manages to be one of the strongest vampires in the series because she was born with potential she hasn't even scratched the surface of yet.
Her upbringing explains the laziness too. Her mother Haru disappeared when she was young, leaving her with Kabura Honda, another vampire who acted as a foster mother. Kabura taught her the basics but didn't impose any strict vampire code. So Nazuna grew up doing whatever she wanted, developing this free-spirited personality that rejects the gothic tragedy stereotype. She's been alive for decades, probably in her 30s or 40s despite looking like a teenager, and she spends that time playing fighting games and sleeping through the day.
The Visual Design Actually Works
Let's talk about her look because it's distinctive for a reason. She's short, barely taller than middle schooler Kou Yamori, with these twin braids tied into ring shapes on each side of her head. In the manga she was originally blonde, but the anime changed her hair to this pale purple color that matches the show's nighttime aesthetic. Her eyes have these weird concentric circle patterns that make her look slightly off, like she's not quite human, which fits perfectly.
The design makes her seem slightly older than Kou despite her height, which adds to that age-gap dynamic that makes some viewers uncomfortable. But visually, she stands out. While other vampires in the series dress like they're trying too hard, Nazuna wears a black coat over a revealing top and shorts, looking like she just grabbed whatever was clean. It's sloppy but intentional, reinforcing that she doesn't care about appearances despite being objectively attractive.
The anime's color palette, all purples and blues and neon city lights, was built around her nighttime wanderings. When she floats upside down with Kou against the starry sky, it creates these gorgeous visuals that became the show's trademark. The artwork gets described as a moving painting by viewers, and Nazuna is usually the focal point of those beautiful nighttime scenes.
She Works Minimum Wage Jobs Despite Being Immortal
One of the weirdest details about Nazuna Nanakusa is that she has a day job, or rather a night job. She runs something called a snooze shop, which is basically a service where she helps insomniacs fall asleep so she can drink their blood. It's a weird business model but it shows she needs money like everyone else. Later she picks up a second job working as a maid at the Vamp Maid Cafe, not because she cares about the work, but because the salary is good and they let her drink beer after her shift.
This is hilarious because she's functionally immortal with superpowers, yet she's worried about rent money and paychecks. It grounds the character in a way that makes her relatable despite being a vampire. She's not living in a castle with piles of gold, she's scraping by in a studio apartment worrying about utilities. She's been described as having a laid-back neutral-good personality which fits someone who works service jobs but uses the position to ethically source blood without killing people.
The Romance Rules Make No Sense But Drive Everything
The central plot mechanic of Call of the Night is that Kou Yamori wants to become a vampire, but the only way to turn is to fall in love with the vampire who bites you. This creates a weird tension where Nazuna is drinking his blood regularly, an act that's portrayed with heavy sexual undertones and embarrassment for Kou, but she absolutely freaks out if anyone mentions actual romantic love. She'll make dirty jokes all day long, tease him constantly, sleep in the same bed, but say the L-word and she melts down.
This contradiction is the heart of her character. She's bisexual, shown to have interest in both Kou and the detective Anko Uguisu, and she's incredibly open about sexual topics. She's very open about sexual topics and enjoys teasing others with her humor. But genuine emotional intimacy terrifies her. It's suggested that her decades of isolation and her abandonment issues from her mother created this defense mechanism where she can handle physical closeness and blood drinking but runs from love.
The age gap makes this weirder. She's physically young-looking but mentally in her 30s or 40s, while Kou is 14. The show tries to handwave this by saying she's emotionally stunted from her vampire upbringing, which keeps her at his mental level, but it's still sketchy. However, some analyses suggest that this arrested development is real, not just an excuse, making her act more like a peer than a predator. Either way, the dynamic drives the story because Kou has to figure out if he can even fall in love given that he's heavily implied to be asexual or aromantic.
Her Powers Are Broken But She's Lazy About Them
Nazuna could be one of the most dangerous characters in the series if she tried. She has superhuman strength that lets her casually destroy concrete, speed that makes her faster than the human eye can track, and regeneration that lets her survive gunshots or severed limbs. She can phase through solid objects by vibrating her molecules or something, though it requires concentration. She can even manipulate memories through blood consumption and has a supernatural charm effect that draws people to her.
But she doesn't train. She doesn't practice. She spends her nights drinking beer and playing games instead of mastering her abilities. She has the highest potential for growth among her peers because she's only scratched the surface of what she can do. Other vampires who are centuries old and have trained properly can beat her in a fight because she's complacent. It's frustrating to watch because you know she could be unstoppable, but she's too busy being lazy.
She does have weird weaknesses though. Every vampire has a preserved umbilical cord that can be used against them, and weapons from their human past can hurt them. Despite being a vampire, she's also anemic, which is ironic and probably related to her half-human heritage. These limitations keep her from being completely overpowered despite her birth advantages.
Why She Carries the Entire Show
Let's be honest about Nazuna Nanakusa's character and role in Call of the Night. Kou Yamori is fine as a protagonist, he's relatable, antisocial, poetic in his internal monologue, and going through a coming-of-age arc about accepting his introversion. But he's boring compared to her. She outshines the main character in popularity despite his own significant fanbase because she's the one doing the heavy lifting in every scene.
She's funny, teasing, mysterious, vulnerable, and dangerous all at once. When she's on screen, the show has energy. When it's just Kou wandering around thinking about his feelings, it drags. The anime is at its best when they're together exploring the city at night, her floating above him while he walks, trading banter about video games or the nature of humanity. She's the one who introduces him to the vampire world, who teaches him about love and loneliness, who creates the atmosphere that makes the show worth watching.
Nazuna serves as the deuteragonist but functions as the mentor, the love interest, and the comic relief all in one. She's the supernatural element that makes the slice-of-life parts work, and the slice-of-life elements that make the supernatural parts grounded. Without her, Call of the Night is just a show about a kid who can't sleep. With her, it's a story about finding freedom in the night and figuring out if connection is worth the risk of heartbreak.
The Supporting Cast Can't Compete
Other vampires show up eventually, Detective Anko Uguisu gets involved, Kou's friends from school appear, but none of them hit the same way Nazuna does. Anko is interesting as a foil, a human obsessed with hunting vampires who has her own complicated relationship with Nazuna, but she's not the focus. The other vampires like Seri or Midori have their own gimmicks but lack the screen presence.
This creates a problem in Season 2 when the world expands and other characters get development. Some viewers noted that while the main characters are good, the supporting cast are even more interesting, but I disagree. Nazuna remains the anchor. When the plot gets convoluted with vampire politics and Kou's impending deadline to either turn or die, she's the emotional core that keeps you caring. Her fear of love, her growing attachment to Kou despite that fear, her struggle to understand her own humanity after decades of detachment, these are the stakes that matter.
Nazuna Nanakusa isn't just a cute vampire girl with funny hair. She's a fully realized character with abandonment issues, a fear of intimacy, immense power she doesn't respect, and a lifestyle that rejects traditional vampire tropes in favor of modern slacker culture. She drinks beer, plays video games, makes dirty jokes, and happens to be one of the strongest creatures in the city. That's why she's the real reason Call of the Night works. Kou provides the point of view, but Nazuna provides the reason to keep watching.
