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.
One possible analysis could be that it allows for a more personalized take on the 'Owari no Seraph' universe. OC (original character) fanfictions often bring in new storylines and character dynamics. It might explore relationships between the existing characters in the series and the newly created OC in unique ways, such as a romantic relationship or a friendship that changes the course of the story.
It's mainly about the story in the 'Owari no Seraph' universe presented in a visual novel format. It likely involves the complex relationships between the characters, the battle against vampires, and the struggle for survival in a post - apocalyptic world.
One possible fanfic could be about Mika and Krul forming an unexpected alliance. Maybe they have to work together to face a common enemy that threatens both of their existences. In this story, Mika might start to see Krul in a different light, not just as a vampire but as someone with her own motives and desires.
Their relationship can be further explored by focusing on their non - verbal communication. Since Nezuko can't speak much as a demon, the looks they exchange, the way Tanjiro gently touches her head to reassure her, these small gestures can be delved into. For example, in a dangerous situation, Tanjiro's glance at Nezuko could convey a whole world of trust and protection.
A great plot idea could be that Nezuko develops a new power that only works when she and Tanjiro are in close proximity. This power could be crucial in fighting a powerful upper - rank demon. For example, she might be able to create a protective shield around them both. Another could be a fanfiction where Tanjiro and Nezuko are invited to a demon slayer gathering in a far - off land. There, they meet other slayers from different regions and learn new techniques. Along the way, they also have to deal with some demons who are trying to infiltrate the gathering.
Well, Nezuko passes Sanemi's test through a combination of factors. Firstly, her strong willpower helps her stay calm and composed. Secondly, her bond with Tanjiro gives her the strength to overcome the challenges. Finally, her inherent kindness and desire to protect others shine through, convincing Sanemi.
