The cutest couples in Demon Slayer
From tragic love stories to unexpectedly sweet pairings, Demon Slayer has given fans plenty of romance to root for.
Some couples had their love cut short by battle, while others were lucky enough to build a future together. Let’s dive into the cutest couples in Demon Slayer and what made each relationship so special.
5. Mitsuri Kanroji and Obanai Iguro
Mitsuri Kanroji, the Love Hashira, and Obanai Iguro, the Serpent Hashira, shared one of the most emotional and tragic romances in Demon Slayer.
While their love story was subtle throughout the series, it was clear that Obanai had deep feelings for Mitsuri, always looking out for her from the shadows. Mitsuri, in turn, found comfort and safety in Obanai’s presence, though neither of them openly confessed their love until the very end.
Both fought bravely during the final battle against Muzan Kibutsuji but suffered fatal wounds. In their last moments, they finally acknowledged their feelings, with Obanai promising that if they were reborn, he would make sure they lived a happy life together.
Their love, though brief, left a lasting impact on fans, making them one of the most beloved pairs in the series.
4. Zenitsu Agatsuma and Nezuko Kamado
Zenitsu Agatsuma was head-over-heels in love with Nezuko Kamado from the moment he first saw her, even though she was a demon at the time. While his affection for her often came across as exaggerated or comedic, there was no denying his devotion. He constantly dreamed of protecting her and proving himself worthy, even when others doubted him.
Nezuko, on the other hand, never spoke much during the majority of the series, leaving fans unsure of how she truly felt. However, by the end of the story, it’s revealed that Zenitsu’s persistence paid off—he and Nezuko ended up together, living happily after the Demon Slayer epilogue.
While their relationship had a humorous start, it ultimately turned into one of the sweetest love stories in Demon Slayer.
3. Inosuke Hashibira and Aoi Kanzaki
Inosuke Hashibira and Aoi Kanzaki first met at the Butterfly Mansion, where Aoi oversaw the rehabilitation of injured Demon Slayers. Unlike Tanjiro and Zenitsu, Inosuke struggled with Aoi’s strict training and was more aggressive toward her. However, he eventually adapted and surpassed her in various tasks, proving his growing ability.
When Tengen Uzui needed volunteers for a dangerous mission, Inosuke stepped in so that Aoi wouldn’t have to risk her life. After the battle against Upper Rank Six, Aoi was deeply worried about Inosuke’s condition, believing he wouldn’t survive his injuries. However, when he recovered and reappeared unscathed, her concern quickly turned into frustration as they resumed their usual bickering.
Inosuke and Aoi’s relationship took a softer turn when Aoi caught him stealing food but instead gave him a special tray prepared just for him. While their interactions were subtle, the manga’s epilogue confirms that Inosuke and Aoi eventually married and had a great-grandson, Aoba Hashibira.
2. Tanjiro Kamado and Kanao Tsuyuri
Tanjiro Kamado, the compassionate and determined protagonist of Demon Slayer, shares a meaningful relationship with Kanao Tsuyuri, a quiet and disciplined member of the Demon Slayer Corps. Raised in harsh conditions, Kanao was taught to suppress her emotions and rely on a coin flip to make decisions. However, Tanjiro’s kindness and determination slowly helped her break free from this habit, allowing her to express herself more openly.
Over time, Kanao’s feelings for Tanjiro became clear, and she showed deep concern for his well-being, even crying with relief when he recovered from life-threatening injuries. Their bond reaches its most pivotal moment during the manga’s final arc.
After Tanjiro is turned into a demon, Kanao risks her life to save him, using the last of the rare medicines created from Wisteria flowers to restore his humanity. This selfless act highlights the depth of her love and admiration for him.
The manga’s epilogue reveals that Tanjiro and Kanao end up together, with their descendants, Kanata and Sumihiko Kamado, living peacefully in a world free from demons. Their love story, built on quiet moments and unwavering support, adds a heartfelt layer to Demon Slayer’s conclusion.
1. Tengen Uzui and his three wives
Tengen Uzui, the flamboyant Sound Hashira, shares a unique and profound bond with his three wives: Makio, Suma, and Hinatsuru. This polygamous arrangement stems from his shinobi background, where such practices were customary. However, Tengen’s relationship with his wives transcends traditional norms, highlighting mutual respect and affection.
Tengen holds them in the highest regard, often expressing his admiration and ensuring they prioritize their well-being over missions. This approach contrasts with their upbringing as kunoichi, where the mission often precedes personal safety. Tengen’s insistence on valuing their lives first underscores his profound love and respect for them.
Throughout their journey, Tengen’s dedication to his wives is evident. During the Entertainment District Arc, he infiltrates the Yoshiwara District to locate his missing wives, displaying unwavering determination to ensure their safety.
Upon reuniting, he reassures them, acknowledging their efforts and expressing relief at their well-being. This deep connection and mutual care make Tengen and his wives one of the most compelling and heartfelt relationships in the Demon Slayer series.
