Definitely. The previous installments of Demon Slayer Hinokami Chronicles have been great, so the new story has a high chance of being just as good or even better. With new plot developments and potential improvements in graphics and gameplay, it's a great addition to look forward to.
I think we can look forward to more in - depth exploration of the existing characters' backstories. For example, we might learn more about Tanjiro's family history that we haven't known before. And there could be new forms of combat techniques, perhaps some ancient ones that are rediscovered in this new story.
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.
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.
