Jesus Christ, why is there nothing for flame daddy? We're fixing that today. Requests are open, smut and fluff accepted. God wanted me dead and now you get to find out why.

This started as a small idea. Just a bit of a "what if..." but since I love Kimetsu no Yaiba too much, it spiralled out of control and well... I have a lot planned, but I'll take it one at a time. So! This is a Reader x Rengoku au story. Of course, there's scenes with other characters and a whole plot I kinda have planned out but Rengoku is a bab so I'll try to focus mostly on him. The au affects him too so- Ahem! Anyways, it'll start a bit slow and I don't have a set update schedule so I hope you'll bear with me. Hope you enjoy the story! Disclaimer! Kimetsu no Yaiba and all it's characters belongs to Gotouge Koyoharu, the only thing I own is this plot and the Breath of Sparks. Warnings/Triggers : MANGA SPOILERS, violence, blood, death, language(mostly cuz Sanemi), angst, dismembered demon parts(?), idek what to put in this, crippling diabetes (I hope), and Rengoku's overwhelming fabulousness.

At a very young age Rina has had a rough knowing nothing but being chained down by her own father but one day she gets the courage to do something for freedom and along the way by chance she meets a young boy by the name of Kyojuro Rengoku and there relationship blossoms from there
