The 'Subliminal Man Story' may focus on the journey of the main character, the subliminal man. It could be set in a dystopian future where subliminal messaging has become a powerful tool for those in power. The man might be an ordinary person at first, but as the story unfolds, he becomes aware of the subliminal world around him. This new awareness could lead him to fight against it, or perhaps try to use it to his advantage in some way. It could also delve into the moral and ethical implications of using subliminal messaging in society.
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.
It could be a theme of self - discovery. The subliminal man may initially be unaware of the hidden forces affecting him. As the story progresses, through his experiences and encounters, he discovers more about these subliminal aspects within himself and the world around him.

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.
