If you’ve read Assassination Classroom or watched the anime, then you know Nagisa Shiota is one of the most fascinating characters in the entire story. With his calm personality, sharp assassin instincts, and androgynous appearance, he quickly became a fan favorite. But outside of all the action and life-or-death tension, fans often wonder about his future. What happens to Nagisa after Class 3-E graduates? And most importantly, who does Nagisa end up marrying? Let’s take a closer look.
Throughout most of Assassination Classroom, romance isn’t really the focus. The story centers on the students’ growth, their bond with Korosensei, and their mission to prevent the destruction of Earth. But even within all that, we see hints of relationships forming between classmates.
Nagisa, despite his reserved nature, stands out because of his close connections with Karma Akabane and Kaede Kayano. Both relationships fuel endless fan debates. Some fans swear by the intense bond between Karma and Nagisa, while others point to the more romantic undertones between Nagisa and Kayano.
Kaede Kayano is probably the most obvious romantic possibility for Nagisa. Their relationship develops naturally over the course of the series. While Kayano starts out hiding her true identity and motives, her friendship with Nagisa grows deeper after her backstory is revealed.
The turning point comes when Nagisa kisses Kayano in an attempt to calm her down during a critical fight. While this moment is more practical than romantic in context, it still plants the seed in fans’ minds. Could these two end up together after graduation?
Nagisa’s kiss with Kayano is often discussed among fans as one of the rare overtly romantic scenes in the manga. But was it truly about love? On one hand, it was Nagisa’s quick thinking to stop Kayano from losing control. On the other hand, it shows that their relationship had a closeness that went beyond normal classmates.
Some readers interpret this as a sign that Nagisa may have romantic feelings for Kayano, even if he doesn’t realize it himself in the moment. Others see it as an act of compassion rather than love. That ambiguity is part of what makes Nagisa’s future such a mystery.
The original manga doesn’t give us a detailed breakdown of everyone’s married life or long-term relationships. For Nagisa, we know that he becomes a teacher, following in Korosensei’s footsteps. This makes sense, as he always had a natural ability to understand and guide others.
But when it comes to marriage, the manga leaves things open-ended. We don’t get an official confirmation of who Nagisa marries. This lack of closure is exactly why fans continue to speculate and create theories.
So, who does Nagisa marry? Let’s go over the most popular theories:
Nagisa marries Kayano
This is the most widely accepted theory, supported by their kiss, their strong bond, and Kayano’s affection for him. Many fans believe that if any relationship were to become canon, this would be the one.
Nagisa and Karma as a possibility
While not canon in the manga, the strong chemistry between Nagisa and Karma has fueled countless discussions. Their deep trust and playful yet intense relationship make them one of the most shipped pairs in the fandom. For LGBTQ fans, this interpretation is especially meaningful.
Nagisa remains single or ambiguous
Some fans argue that leaving Nagisa’s marriage open-ended fits his character best. Instead of focusing on romance, the story ends with him dedicating himself to teaching, carrying forward Korosensei’s legacy.
What’s interesting is that the creator, Yusei Matsui, didn’t feel the need to resolve every romantic question. Assassination Classroom is about growth, self-discovery, and acceptance. By leaving Nagisa’s marriage unanswered, it allows fans to interpret his future however they like. Whether you see him with Kayano, Karma, or living happily on his own, the choice is yours.
The reason “Who marries Nagisa?” keeps coming up is simple: Nagisa is a character who resonates deeply with readers. His struggles with identity, his unique assassin abilities, and his kind heart make fans invested in his future. Romance is just one way of imagining how his story continues beyond graduation.
Plus, when a character is written with so much nuance, it’s natural for fans to want more closure. The manga may have ended, but the conversation about Nagisa’s life hasn’t stopped.
If you want to revisit Nagisa’s story and re-experience the journey of Class 3-E, you can check out the full series and fan discussions at Assassination Classroom manga. It’s the best way to dive deeper into his development and see why he continues to spark so many questions about his future.
So, who marries Nagisa? The honest answer is that the manga never confirms it. But that’s not necessarily a bad thing. The open ending gives fans the freedom to imagine their own version of Nagisa’s happily ever after. Whether you believe he ends up with Kayano, Karma, or remains dedicated to his career, the important part is that he’s grown into someone who values his own identity and follows his own path.
At the end of the day, Nagisa’s story isn’t just about romance. It’s about transformation, acceptance, and carrying on the lessons of Korosensei. And that’s why his character will always be remembered, no matter who he marries in the hearts of fans.
