One popular 'zenitsu x nezuko fanfic' is 'The Unlikely Bond'. It beautifully portrays the relationship between Zenitsu and Nezuko. The author does a great job of showing Zenitsu's protective nature towards Nezuko and how Nezuko's presence calms Zenitsu in his often-fearful state.
Nezuko remains alive in the Demon Slayer manga. The author chose to keep her alive as she is an important character with a vital part to play in the overall narrative.
A simple Nezuko and Zenitsu fanfiction could be that they go on a journey together. Along the way, they encounter other demon slayers who are initially skeptical of Nezuko. But Zenitsu stands up for her, explaining that she's different. This shows the depth of their friendship and how Zenitsu has come to trust Nezuko completely.
Definitely not. In the manga, there's no such plotline of Zenitsu and Nezuko getting married. Their relationship is more focused on being comrades in the fight against demons rather than a romantic one leading to marriage.
One common theme is the development of their relationship. It often shows how Zenitsu's initial fear or admiration for Nezuko turns into deeper feelings. Another theme could be their adventures together, fighting demons side by side in some fanfictions.
Well, a lot of it has to do with the potential for character development. In the original story, their interactions are limited, but in fanfics, authors can explore how they would grow closer and influence each other. For example, Zenitsu could become more confident because of Nezuko, and Nezuko could learn more about the human side of relationships through Zenitsu. It's also about the fans' love for the two characters and their desire to see them in different scenarios together.
You can try looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms usually have a large collection of fanfictions, including those related to Nezuko and Zenitsu.
A Nezuko and Zenitsu fanfiction might explore the concept of Zenitsu teaching Nezuko about the human world. Since Nezuko has been a demon for a while, she may have forgotten some aspects of human life. Zenitsu could show her simple things like how to enjoy a flower's beauty or the taste of human food (in a non - harmful way for her). This could create a really sweet and heartwarming story as they bond over these new experiences.
