Sure. There are quite a few. Some fanfictions might be centered around their growth as characters. Tanjiro's journey to become a stronger demon slayer while protecting Nezuko, and Nezuko's own development as she tries to resist her demonic instincts. They could be in various genres like adventure or even some light - hearted slice - of - life stories within the context of the 'Demon Slayer' universe.
It's not easy to say who has the upper hand. Archer has the advantage of experience and a more complete set of skills. But Shirou has his own tenacity and the ability to surprise. In different situations during the battle, either of them could seem to be in control for a while.
Tanjiro might use his sense of smell to detect hidden threats. Since his sense of smell is super - enhanced, he could sniff out any demons or traps in the way of saving Rengoku. For example, if there are demons disguised as allies, Tanjiro would be able to tell by their scent.
Well, it varies. In some stories, the Daleks' sheer power and ruthlessness give them the edge. But in others, human ingenuity, courage, and unexpected alliances can tip the scales in their favor.
Yes, in some fanfictions, Tanjiro is depicted as the reincarnation of Yoriichi. This concept adds an interesting layer to the story as Yoriichi was an extremely powerful and legendary figure in the original lore. The idea allows for new storylines where Tanjiro might inherit some of Yoriichi's skills or have a deeper connection to the past events related to Yoriichi.
Tanjiro's fate in the manga is that he ultimately passed away. This event was a significant part of the story's development and had a profound impact on the other characters and the overall plot.
