Ripples a Muichiro tokito x (y/n) story

(Y/n), a 13 year old girl who lost the only people she cared about felt hopeless, until.. Amane Ubuyashiki found her hopeless and scared. Taking her under her wing, what happens when she meets a boy only a year older? Maybe he's cold, but shes determined to befriend him.
(Cover art not mine,
I don't own any of the characters except (y/n) all credits go to Kimetsu no Yaiba)

This isn't just any fanfiction, this is my attempt of creating a character and a good backstory, and a very interesting love life as I want it to be complex, I also will say that it won't be like every chapter is about Muichiro x (y/n) because I want to build a good story. NO SMUT cause this boy is 14! And that's wrong!!
