Tanjiro and Kanao's love is a slow - burning and sweet one. They first meet as comrades in the fight against demons. Tanjiro's kind heart and strong will gradually draw Kanao out of her shell. Kanao, who was initially rather reserved, starts to open up more because of Tanjiro. Their relationship develops as they face numerous challenges together, and their mutual respect and growing affection for each other are heartwarming to watch in the series.
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.
In fanfiction about Naruto and Demon Slayer with magic, one interesting aspect is the potential for new power - ups. For instance, a character could combine the Sharingan from Naruto with a Demon Slayer's special vision ability and create a super - powered form of sight. Also, the magic could be used to explain some of the more mysterious elements in both series. Maybe the curse marks in Naruto are actually a form of suppressed magic, and in the fanfiction, a character figures out how to fully utilize this magic, taking on a new and powerful form inspired by Demon Slayer's demon - slaying forms.
Magic in this type of fanfiction can be used to bridge the gap between the two universes. It can make the transition of characters from one world to another more believable. For example, if Naruto characters enter the Demon Slayer world, magic could be the reason they can adapt to the new rules and powers there.
