The description says it all so yeah ima keep this short and just announce when my next 'idea' for a possible fanfic will happen.
Yes it will be about Tanjiro and I most likely will make it into a fanfic in the near future. All I need is a ship and other then that I have mostly everything covered.
Hint: "Baba yaga"
"The boogie man?"
"Not exactly, he's the one you sent to kill the f*cking boogie man"
