Manga / Call of the Night

Go To

Call of the Night (Yofukashi no Uta) is a manga series written and illustrated by Kotoyama, creator of Dagashi Kashi. The series follows a junior high student named Ko Yamori, who has recently stopped going to school and developed insomnia. Ko starts to wander the streets at night, where he meets and befriends a girl named Nazuna Nanakusa, who turns out to be a vampire. After having his blood sucked and talking to Nazuna, Ko asks her to make him into a vampire, only to learn that in order to become one he must first fall in love with Nazuna.

The manga began serialization in Weekly Shonen Sunday in 2019, and is licensed in English by Viz Media. An anime adaptation has been announced for July 2022.


This work contains examples of:

  • Bland-Name Product: Nazuna owns a Buzaar System by Sunn.
  • Blatant Lies: After Nazuna’s first bite on Ko’s neck, he reveals himself to be awake the whole time. Nazuna says it was a really big mosquito, while there is still blood on her mouth.
  • Childhood Friends: Akira, who lives in the same apartment complex, is Ko's.
  • Crash into Hello: Happens in a dating sim that Ko, Nazuna and Akira were playing in Night 10. And it’s lampshaded and mocked by Ko.
    Ko: What the heck?! There was plenty of room on the street! Why’d she bump into me?!
  • Dynamic Entry: When Seri tries to glomp Ko, Nazuna blocks her by flying in out of nowhere, kneeing her in the face and sending her hurtling head-first into a signpost.
  • First-Name Basis: Ko starts calling Nazuna by her first name in Night 3, to make their relationship feel more equal. This gets her flustered.

  • Freeze-Frame Bonus: Nazuna owns a copy of Darkstalkers: The Night Warriors.
  • Friendly Neighborhood Vampire: Nazuna is the prime example, with her charisma, approachable vibes, and social outlook making her easy to get along with, even with three drunk strangers who have no idea who the hell she is in episode 1.
  • Friends with Benefits: A vampiric version in Ko's relationship with Nazuna, who refers to their relation as a physical one. Along with just hanging out, Nazuna feeds on Ko’s blood once a night, something she compares to... coitus.
  • Genre Shift: From a quirky if dark romantic comedy, to a mystery thriller, to superhuman vampires trying to kill eachother, the series can jump its idea of genre and tone even mid-chapter/episode. It never quite settles into one thing entirely, though, besides the comedy at its core.
  • Get a Room!: Akira in Night 10, when Nazuna starts feeding on Ko right in front of her. Ko also calls her out for it.
    Nazuna: But being watched adds spice, doesn’t it?
    Akira: Don’t use me as seasoning!
  • Guy on Guy Is Hot: Implied by Nazuna in episode 1. Ko mentions he doesn't like girls (in his school at least). Nazuna assumes he's gay and outright says she "approves." But he says it's more complicated than just not having a crush on anyone.
  • Healing Factor: Vampires appear to have this: Seri was able to reattach her severed arm without much issue, while Akiyama's vision got better after he was turned.
  • Horror Hunger: Vampires can go for about 10 years without consuming blood before they lose it. Yamori and his friends were unfortunate enough to find out what that looks like when a vampire assaulted Akira.
  • I Always Wanted to Say That: When Ko proposes to exchange contact info (so he wouldn’t have to keep searching for her), Nazuna does this
    Nazuna: Hey, Ko. There’s something I always wanted to say. Are you ready for it?
    Ko: ….Go ahead.
    Nazuna: Like… do you do Line?
    Ko: Nope, don’t have the app.
    Nazuna: Me neither!
    Ko: Then why’d you ask?!
  • The Insomniac: What sparks the series, as Ko has trouble sleeping and decides to wander at night.
  • Knight of Cerebus: The manga gets slightly less peaceful with the introduction of Seri Kikiyou, who has no issues resorting to violence and who ends up introducing Ko to the other vampire girls, resulting in the one year time limit Ko has to become a vampire, lest the group kills him for knowing too much. The danger meter ticks over once again thanks to Anko Ugiusu and her vendetta against the vampires, which results in the darkest plot arc the series has had to date.
  • Kryptonite Factor: Vampires in this universe are almost entirely immortal with one exception: if they encounter something meaningful from their life prior to being a vampire it opens them up to being killed and if they're exposed to it long enough can kill them outright.
    • Due to her nature as a Dhampyr it was believed that Nazuna didn't have this weakness. Somehow Kiku was able to find something that worked for her though.
  • Male Gaze: Nazuna is the series's resident Ms. Fanservice, and in both the manga and the anime, the 'camera' is usually just as enthusiastic about her appearance and clothing choices as Ko is.
  • Our Vampires Are Different: They have the stock flight, super strength, accelerated healing, long life, and desire to drink blood. However, vampires in this series has a number of differences; most notably, in order to change into one a human must have fallen in love with the vampire first or it won't take. Once a vampire has picked a human to turn, they have a year to get them to fall in love after the first bite or they won't ever turn. This is part of why the vampires we meet have turned being desirable into an almost science to make it happen as fast as possible, which just puts off Ko entirely. Also Vampires in this universe don't have to drink blood regularly, just once every 10 years or so or they'll go berserk.
  • Recurring Extra: Those three drunk men from the first chapter? They show up every now and then, utterly plastered every time and ready for another drink.
  • Saying Too Much: Nazuna is perfectly fine with Ko confessing to Akira that he wants to be a vampire in Night 10. But then she tries to shush him when he reveals ‘’how’’ to become a vampire. To no avail.
  • School Is for Losers: Both of the protagonists’ opinion on school. Ko just finds school so boring that he wouldn’t even visit it in a video game.
  • Skipping School: When the series starts, Ko has stopped going to school.
  • Surprisingly Realistic Outcome: Even vampires need money. Nazuna’s "cuddle buddy” business is an actual business. She points out that this is how she and Ko got entry into a pool party and a love motel.
  • Supernaturally Delicious and Nutritious: According to Nazuna, Ko's blood is incredibly tasty.
  • Titled After the Song: The series is named after a single by Japanese hip-hop duo Creepy Nuts (the mangaka acquired permission to use the name of the song for the manga). Said song also serves as the ending theme song for the anime adaptation to acknowledge this.
  • Tsundere: A milder case with Nazuna. She's very much against falling in love, doesn't want to create more vampires (which can only happen if the person she bites falls in love with her as she bites them), and is upfront to Ko about only wanting a physical relationship ala Friends with Benefits. But she's very flustered when Ko talks about falling in love with her, something he notices every time and also finds rather confusing.
  • Vampires Are Sex Gods: According to Nazuna, vampires have an glamour that attracts humans. All the better to feed. Vampires also turn humans on the condition that they fall in love with them. Nazuna, of course, compares this to reproducing.
  • Vampire Hunter: Anko Uguisu, a detective who turns out to have a grudge against vampires.
  • Vampire Vannabe: Ko's desire is to eventually become a vampire.
  • Your Days Are Numbered: The Vampire girls forbid the knowledge of their existence to be known to regular humans, and are willing to kill them to keep it that way. They make a temporary exception for Ko, who is actively trying to become a vampire… however, he only has a year. Once bit by a vampire, humans only have a year to turn.
