Rengoku is a popular character from the manga and anime series Demon Slayer. As one of the powerful Hashira demon slayers, fans are often curious about Rengoku’s personal life and relationships outside of battle. However, Rengoku is never shown to be married or have a romantic partner within the Demon Slayer story. While he is popular with some female characters, any marriage plans or romantic relationships for Rengoku are purely speculative.
Rengoku’s Background
Before analyzing who Rengoku could potentially marry, it’s helpful to understand his background within the Demon Slayer story. Rengoku is the Flame Hashira, having mastered the Flame Breathing combat style. He comes from a distinguished family of demon slayers, being the eldest son of former Flame Hashira Shinjuro Rengoku. Rengoku is known for his sense of duty, honor, and optimism. He also has a love of food, especially beef bowls.
As a Hashira, Rengoku is constantly traveling and fighting demons. He seems devoted to the demon slayer cause, often putting duty above all else. Rengoku does not have any on-screen romantic relationships or love interests. While respected by many, he is also seen as aloof and distant. Rengoku meets a tragic end in the Mugen Train arc, dying in battle against the powerful demon Akaza. Due to his early death, any future marriage plans are cut short.
Potential Marriage Candidates
Given his limited romantic history, who could Rengoku have possibly married if he had survived? Here are some potential candidates:
Kocho Shinobu
Kocho Shinobu is the Insect Hashira of the demon slayers. She initially has an antagonistic relationship with Rengoku, insulting him upon their first meeting. However, they later develop a mutual understanding and respect. Kocho comes from her own distinguished demon slayer family and shares Rengoku’s dedication to destroying demons. While very different in personality, they find common ground in their ideals and duty as Hashira. Some fans see romantic potential in their dynamic if further developed over time.
Shirai Sumi
Shirai Sumi is a female demon slayer introduced in the second season of the anime. She is a Tsuguko, or successor to a Hashira, showing impressive combat ability. Sumi greatly admires the Hashira, especially Rengoku due to his flames and kind personality. When Rengoku saves her life, Sumi develops a deep respect and crush on him. If Rengoku had survived, some believe Sumi would try to romance him. Their relationship had a foundation of adoration and gratitude.
Mitsuri Kanroji
Mitsuri Kanroji is the Love Hashira, fitting her caring and romantic personality. She thinks Rengoku is handsome upon first meeting him and tries to get closer to him. However, Rengoku maintains professionalism and distance. While not direct love interests in the story, some fans think Mitsuri would continue trying to get Rengoku’s affection due to her interest and see potential in a future relationship between the two Hashira.
Kanae Kocho
Kanae Kocho was Shinobu Kocho’s older sister and the previous Insect Hashira. Though she died before the events of the story, some fans like the idea of Rengoku and Kanae as a possible romantic pairing. They were around the same age and both came from prestigious demon slayer families. As skilled Hashira, they could bond over their talents and experiences. This is entirely hypothetical, but makes for an intriguing story possibility.
Sanemi Shinazugawa
Sanemi Shinazugawa is the antagonistic Wind Hashira. Though they clashed upon first meeting, he and Rengoku developed a mutual understanding. Sanemi gave a degree of praise and respect to Rengoku’s fighting skills. While an unlikely couple due to their harsh relationship, some fans entertain the idea of them bonding more deeply over time through their warrior natures. Their philosophical differences could complement each other.
Nezuko Kamado
Nezuko is Tanjiro Kamado’s younger demon sister. She has a close relationship with Tanjiro. Some fans speculate on a potential NEzuko x Rengoku pairing, with Rengoku helping bring Nezuko back to humanity. However, their limited interactions and age difference make this unlikely. Still, some find the idea of the kind Rengoku helping Nezuko recover her human side through romance imaginatively appealing.
Kanao Tsuyuri
Kanao Tsuyuri is a demon slayer introduced early in the story. Some see potential between her and Rengoku due to their personalities balancing each other out well. Kanao’s reserved nature contrasts with Rengoku’s fiery passion. However, they had minimal interactions, making a relationship difficult to develop. But some enjoy the ‘opposites attract’ dynamic these two could possibly have.
Analysis of Options
Reviewing the potential candidates, Kocho Shinobu seems the most likely choice for Rengoku. They share similar backgrounds, duties, and a developing understanding. Her initial distaste of him could gradually turn to affection through increased contact. Kanroji is a possibility as well, though Rengoku didn’t reciprocate her interest. Sumi’s admiration of Rengoku could also be a foundation for a future bond.
However, many of the options are purely hypothetical and rely on circumstance. Rengoku having limited screen time makes it difficult to conclusively analyze his romantic possibilities. His solitary personality and focus on the demon slayer role gave little indication he sought a relationship during the story. But his tragic early death left his full character potential unexplored.
Conclusion
In summary, Rengoku has no clear canonical romantic relationships or marriage partners in Demon Slayer. His most likely partner would be Kocho Shinobu based on their dynamic and similarities as Hashira from distinguished families. However, Rengoku’s early demise prevented seeing how he developed. Any demonstrations of interest from female characters were mostly one-sided. While fans enjoy speculating about who a surviving Rengoku could marry, his canonical fate left any future relationships tragically uncertain. The question of who Rengoku marries will likely remain a mystery within the Demon Slayer universe.
