I have finished Call Of The Night(my thoughts, maybe spoilers, soooo you’ve been warned)
The ending is honestly really bittersweet in a way that fits the whole series perfectly. It doesn’t go for some huge dramatic climax it stays focused on Kou and Nazuna, and on what “love” actually means for two people who don’t fully fit into normal life. By the final stretch, the biggest conflict is tied to Mahiru and Kiku. Mahiru becomes completely obsessed with Kiku Hoshimi and wants to die together with her in the “romantic vampire” way the series keeps talking about. Kiku herself is kind of tragic because she spent centuries trying to genuinely fall in love with someone but never really understood human connection properly. When Mahiru finally confesses real love to her, it actually works… but instead of becoming her vampire servant, he dies because their relationship was built around escapism and self-destruction rather than mutual understanding. Kiku dies too shortly after, and the whole scene feels less like a villain defeat and more like watching two lonely people collapse together. That moment hits Kou really hard because it forces him to confront what he actually wants from Nazuna. Up until then, their relationship was all teasing, nighttime adventures, awkward flirting, and emotional dependence without either of them properly defining it. Kou realizes that becoming a vampire isn’t just “cool freedom at night” anymore it means changing his entire existence. At the same time, Nazuna starts panicking because she realizes she genuinely loves Kou. The problem is that in the series’ lore, if a vampire truly falls in love with a human they can become vulnerable. Nazuna becomes terrified that being close to Kou could either hurt him or ruin the relationship they already have. So instead of embracing the confession romance payoff most manga would do, she runs away. The final chapters are basically about distance, growing up, and accepting imperfect love. Kou eventually becomes older noticeably more mature and calmer but he never fully gives up on Nazuna. He keeps living his life while still wandering the night. Then years later, Nazuna suddenly returns. Their reunion is quiet and awkward and incredibly “them.” No giant melodramatic kiss, no overexplaining. Just two people who clearly still care about each other after all that time apart. The ending heavily implies they’ll continue their relationship on their own terms. Kou never became a full vampire during the main ending itself, but emotionally he already belongs to the night world. Meanwhile Nazuna finally stops running from her feelings. The manga leaves things open-ended intentionally because the point was never “human boy becomes vampire happily ever after.” It was more about loneliness, freedom, insomnia, adolescence, and finding someone who makes the emptiness of nighttime feel comforting instead of isolating. Even at the end, it still feels dreamy and nocturnal instead of turning into a typical action finale. And honestly, Kou and Nazuna’s relationship staying messy and unfinished feels weirdly realistic for a story about vampires.
