Heres A Interesting Idea What If Tanjiros Father Was A Hashira Before His Illness Became So Bad He Was

Here’s a interesting idea what if tanjiro’s father was a Hashira before his illness became so bad he was forced to retire?

I agree, that is a very interesting idea! I've seen some fanfics use the idea, and I love the story potential.

Especially the comedy that can come from Urokodaki and Shinjurou looking at Tanjirou(AKA Tanjurou's carbon copy/Mini Me) and having to do a double take like, "WHAT DO YOU MEAN THIS IS HIS OFFSPRING AND NOT JUST HIM UNDER A BLOOD DEMON ART?!" A very confusing moment for both of them, when they meet Tanjirou.

And if Tanjurou faced one of the Upper Moons at any point during his career? Demons are either gonna be trying really hard to kill Tanjirou, or they're gonna be running for the hills the second they spot him. Which could prove helpful during a certain train-related incident!

But another interesting facet would probably be the expectations placed on Tanjirou, whether by himself or by anyone who knew his father as a Demon Slayer. Since it's mentioned Tanjurou's potential was on par, or at least close to Yoriichi, I imagine there would be a certain degree of pressure on Tanjirou to live up to that. Maybe not intentionally, but hearing the stories might give him that idea. And who knows how that would affect him during the series?

...

Meanwhile, Tanjurou's in the afterlife thinking about how he left the Corps both due to his illness and to protect his family(if he didn't retire right away after marrying Kie, then I imagine the latest would have been while she was pregnant with Tanjirou). And now his two eldest kids are in the field, Nezuko's a demon, and Tanjirou is fighting.
