The three legendary demon slayers

all of us knows the story of a boy who lost his family from a demon attack and is left with a demon for a sister then he goes on adventure to find a cure to change her back to a human and kill demons along the way...... But this story isn't going to be about him instead we are going to focus on these three people who's names are Daiki, kyoko, and Yurei who will be legends in history

Kyoko and yurei are oc's to two of my friends and they let me use them in this story and Daiki is my oc

(P.S. I'm going to ship kyoko and Daiki in this story and ship tanjiro with yurei and the story of demon slayer goes to the person who made it so don't comment that tanjiro is straight Ik he is but just for now he isn't this is not the actual story ok? Also I will be covering the whole story so spoilers if u don't want the whole story ruined by me then don't read this)
